Chapter 676: Five Thousand Years of Opening Up Wasteland, Amazing Harvests
Chapter 676: Five Thousand Years of Opening Up Wasteland, Amazing Harvests
It’s okay if it doesn’t break out.
Wu Yuan's sudden outburst revealed far more strength than the saints of the Abyss Alliance had expected..
“How can it be so strong?？”
“In these billions of years, he has obviously been taking action and has never shown such terrifying strength.！”
“He has actually cultivated the eternal divine body to the perfect level, which is truly terrifying." Many true saints were shocked and unbelievable..
The material way is very difficult to cultivate.
Many true saints have not even cultivated the eternal divine body. It is considered good to be able to cultivate to a small degree..
The attainment of the Eternal Divine Body is already at the level of most true saints and perfect strong men..
As for the perfection of the eternal divine body? Even if you are the Holy Saint, not everyone may be able to practice it..
But how did these true saints know that compared to the laws of his own way, Wu Yuan had an earlier breakthrough in the way of matter, and he had incredible talents on this path?.
the most important is.
As the master of the Tao of Creation, he has unique advantages in cultivating the way of matter..
Just like the previous Taoist Master of Creation, the Taoist Mountain, the way he opened up was not very strong, but he cultivated it into a black and yellow body and gained an astonishing reputation..
Whoosh！
Wu Yuan's speed was astonishing, and the innate treasure wings on his body made his already exquisite body skills even more terrifying. His body was majestic but extremely flexible. He caught up with the fleeing true saint in just a few moves..
Wu Yuan's eyes were cold, staring at him as if staring at a dead person.
“Not good." The true saint was indeed panicked and furious: "Save me! help me！”
It's just that the battle situation changes too quickly.
From Wu Yuan suddenly bursting out and sweeping away more than a dozen true saints, to specifically hunting down one true saint, it all happened in the blink of an eye..
At this moment, the true saints who were close were just blasted away, and they were all afraid. As for the ones who were far away? It's too late to save.
suddenly.
“Fellow Taoist Wu Yuan, there is a misunderstanding! Misunderstand! Stop looking at your hands." A rapid voice sounded from the side of the void, and it instantly resounded through the endless void through the fluctuations of time and space..
Whoosh! A black-robed figure was flying through the formation full of hazy light, flying over quickly.
“It's Mo Linzhensheng.”
“He's still here? With such great strength, he didn't even break into the Tenth Ruins Realm? "The other true saints who were fighting against the true saints of the Abyss Alliance immediately noticed the coming person..
“True Saint Mo Lin is here, be careful." True Saint Tianpeng also sent messages to Wu Yuan. With his strength, it is easy to resist the attacks of nearly ten true saints, but it will be difficult to escape even for a while..
but.
Wu Yuan simply turned a deaf ear to him. Hundreds of thousands of miles away, he passed by him in an instant, as easily as if he had taken one or two steps in ordinary life, and caught up with the true saint of the strange beast..
The dazzling sword light erupted immediately after！
“ah! ! Damn it! "The True Saint, a strange beast from the Abyss Alliance, roared angrily. He suddenly waved his hoofs and claws and attacked fiercely, trying to block Wu Yuan's attack..
“block him.”
“quick! "Other true saints are also coming quickly..
“Wow!~”
Wu Yuan flew directly past the True Saint of the Alien Beast, and saw the mighty sword light directly drowning his opponent. The terrifying impact contained in the sword light directly bombarded the eternal heart of the True Saint of the Alien Beast to pieces. Cracked.
Two fights.
A true saint fell！
Even Wu Yuan did not have to use the Chaos Spiritual Treasure Saber. This is because the strength of the alien beast True Saint is too weak, and it is not even the peak strength of the True Saint..
“What？”
“This sword technique! It’s so scary, I’m afraid it’s almost at the holy level..”
“Even if he has not reached the threshold of the Holy Saint, he is definitely not far away. Run away! "This group of true saints from the Abyss Alliance were frightened..
It's really scary！
“escape！”
“Leave quickly." The other Abyss Alliance True Saints did not dare to stay any longer and fled in all directions. They really did not dare to stop them anymore..
They had only been fighting for a long time, and one of them died.？
If we continue to fight, I'm afraid they will all die..
“Wu Yuan, you are too bold." True Saint Mo Lin, who was coming from a very far away place, shouted angrily: "Stop immediately, we will let you pass. If you continue to kill, you will force hundreds of us True Saints to go. Surround you with all my strength.”
Zhensheng Mo Lin is indeed in a hurry. He was ordered to guard the formation. Logically, there is not much danger..
What if you meet someone with super strength? They just let it go. For example, Qingyan Zhensheng was let go by them..
Then, when there are too many true saints who have invaded here, and they reach 200, the formation will be withdrawn..
In essence, it is to delay as much time as possible and create more conditions for the true saints of the Abyss Alliance who have broken into the Tenth Ruins Realm..
Where can I think of it.
Wu Yuan, who was described as "attack-like" in Wanyulu's intelligence, was actually so powerful in battle..
“Surround and kill？”
“At this point, you still dare to threaten me? "Wu Yuan's eyes were cold, and he glanced at the dozen or so escaping true saints. He suddenly became murderous..
Wu Yuan's principle is to repay grudges tenfold.
It’s just that it’s not easy to kill.！
If the Dharma Body were to take action, using the Chaos Spiritual Treasure 'Original Golden Lotus' to control a space and time and suppress dozens of true saints would be ordinary, allowing Wu Yuanyuan to kill with ease..
However, Wu Yuan has not even entered the tenth ruin realm yet, and Wu Yuan does not want to reveal his trump card now..
The purpose of exposing the perfection of the eternal divine body is to scare Xiao Xiao, there is no need to expose more methods..
“Use another move." Wu Yuan thought, and immediately nine swords flew out from his palm at the same time..
Flying to the void in all directions.
Wow! Wow! Wow! The nine innate treasure swords flew tens of millions of miles in the blink of an eye, instantly causing the 'black and white field' to change and become even more terrifying. A stream of terrifying sword light was born in the field..
This is the world of knives！
The world of knives.
The change of moves was too fast. Under the suppression of the domain, eight of the twelve true saints who fled had not had time to escape..
These eight true saints all felt the amazing oppression of the black and white realm, and they were much stronger than before..
“field？”
“The secret technique of long-distance attack? When Wu Yuan was born in Changhe, he was originally a body refining stream. His secret technique of long-distance attack is not worth mentioning, and his power may be limited." Zhensheng Mo Lin thought this in his heart..
There are many true saints who think the same way as him.
Everyone’s energy is limited, and the most important thing is that one’s own path is hard to change. The experience of a long life stage will greatly affect one’s own path forward, so most of the eternal strong men are only good at one or two aspects..
Even if you study concurrently, it is difficult for most people to reach the top..
“Black and white knife field, explode! "Wu Yuan's eyes were cold, and he had already activated the nine-handed innate treasure sword that was integrated with the black and white domain..
In an instant.
The sword light in the entire field exploded, like a budding flower suddenly blooming, emitting a dazzling light.
It was as if a star filled with blades exploded, impacting in all directions..
Nine swords！
Mainly attacking the three weaker true saints. They are all ordinary true saints..
Poof~
Peng~
Pfft~ The eight true saints had no time to escape, and they were hit by the overwhelming sword light impact. Only two domain sword light impacts caused the three true saints who were severely attacked to completely fall..
As for the other five true saints, they were also severely injured, but they finally escaped from Wu Yuan's domain..
So far.
Of the thirteen true saints who besieged Wu Yuan, four fell..
“Sure enough, I'm still not very good at long-range attacks. If I were controlled by the Dharma Body, it would only be more terrifying." Wu Yuan frowned slightly..
It’s hard to take care of other true saints.
But they are different. Although the two deities have unique ways, they have many insights and cultivation experiences in common. The most important thing is that the eternal powerhouse has unique magic power. In essence, it can control both melee and long-range attacks at will..
so.
In addition to deducing his own way, Wu Yuan, the body-refining deity, would occasionally combine domain secrets and long-range attack sword formations to form a long-range attack killer move 'Black and White Sword Domain', which would naturally not work against super strong people..
A move like Wu Yuan's is very difficult to deal with the peak True Saint, and it is difficult to kill him quickly..
But if you want to kill some ordinary true saints, it is easy. You can kill them with the flip of a palm..
“It's a pity that my mental capacity is limited.”
“You have to go all out to use the Black and White Sword Domain, and it will be difficult to maintain the peak of melee combat." Wu Yuan thought thoughtfully..
For the strong, to manipulate powerful magic weapons and perform powerful secret techniques, consuming mana is only one aspect..
The most important thing is that it is mentally draining.
……“this？
“Such a secret skill, Wu Yuan's long-range attack is actually so terrifying！”
“How is it possible? Doesn't he have any shortcomings? "The scene of Wu Yuan turning his palm to kill the three true saints made the many true saints in the void in all directions even more shocked..
As true saints, they have a good vision and can all see that the secret technique of long-distance attack that Wu Yuan just performed can definitely be regarded as the perfect level of true saint..
If not, how could we quickly kill several true saints?？
Melee combat is almost at the level of the Holy Saint, and long-distance attack is also at the Perfect Saint level? The material defense is incredible.
Just thinking about it makes these true saints tremble with fear.
So perfect, no flaws*.
Wow~ Wu Yuan did not continue to chase, but waved his hand and quickly collected all the treasures left by the three true saints, dedicating a little of his energy to exploration..
The rewards of adventure are not as fast as the killings.？
call！
A black stream of light passed through the void and landed not far from Wu Yuan. It was the True Saint Mo Lin..
“True Saint Wu Yuan, your murderous intention is too serious." True Saint Mo Lin stared at Wu Yuan and said in a low voice: "I told you to let you go, why bother to kill again?？”
“Revenge of the fall, these true saints will eventually revive.”
“Why should we have such a big hatred? "Zhensheng Mo Lin said in a low voice, seemingly angry, but also a little puzzled: "We have hundreds of real saints coming together, you may not be able to kill them all, right?.”
Whoosh! Whoosh！
Not far away, the True Saints of the Abyss Alliance who were besieging True Saint Tianpeng were quickly retreating..
At this moment, hundreds of true saints in the void were all looking at True Saint Mo Lin and Wu Yuan..
“Murderous？”
Wu Yuan suddenly smiled, then his smile faded, and his voice was cold: "I have said long ago that anyone who blocks my way will die.！！”
“Mo Lin, I have only killed four now, so I have shown mercy. If you, the Abyss Alliance, are not convinced, you can fight again..”
silence.
True Saint Mo Lin stared at Wu Yuan with great reluctance. He was also one of the top 100 true saints and commanded hundreds of true saints to guard here..
He really wanted to give an order to besiege Wu Yuan with all his strength..
But he knew he couldn't！
Regardless of whether Wu Yuan can be killed or not, after Wu Yuan showed such terrifying strength, few of the hundreds of true saints on the Abyss Alliance side were willing to continue to kill him..
True saints are not willing to give away their lives in vain..
After half a breath of silence.
True Saint Mo Lin took a deep breath and forced a smile: "Okay! True Saint Wu Yuan, I respect you. This time it is our Abyss Alliance who is at fault, but the several true saints you killed, can you return the treasures they left behind?" Give us？”
“This is my trophy." Wu Yuan said indifferently: "I have never been in the habit of returning treasures..”
Mo Linzhensheng became more and more angry in his heart, but also felt a sense of powerlessness. He could only try to suppress the anger in his heart..
quite a while！
“good! "Zhensheng Mo Lin gritted his teeth and almost said a sentence from between his teeth: "Make way for Zhensheng Wu Yuan..”
Rumble~
Like a tide, the true saints of the Abyss Alliance who had long been unwilling to fight with Wu Yuan immediately made way for a passage in the void..
“Tianpeng, let’s go.” Wu Yuan greeted.
“good.”
Whoosh! Whoosh！
Wu Yuan and Tianpeng True Saint turned into two streams of light, and rushed into the depths of the space-time rift, quickly disappearing from all the True Saint inductions..
“Stop the rest of them." True Saint Mo Lin said in a low voice, his eyes fiercely swept over True Saint Kuang She and the others..
It seems like he wants to vent his anger.
“This sage Wu Yuan actually doesn’t want to take us with him.”
“The Abyss Alliance actually surrendered.”
“This group of bastards bully the weak and fear the strong." Kuang Sheng Zhensheng and the others all felt aggrieved and a little helpless..
Wu Yuan didn't want to take them with him. As they expected, they were both competitors. It would be fine if they didn't kill them. How could he be willing to help them?？
However, they did not expect that after the Abyss Alliance lost four true saints, they would actually bow their heads..
If the two sides continue to fight, they will have an opportunity to take advantage of it..
……
This battle broke out at the entrance to the Tenth Ruins Realm. Many true saints watching the battle came from many major forces..
Wu Yuan has exploded with such terrifying strength, and the Tenth Ruins Realm is now the focus of many powerful forces in the sea. Therefore..
Very quickly, news about this battle spread like a hurricane.
“Eternal Divine Body Perfection？”
“The strength of True Saint Wu Yuan is even more terrifying than imagined! His material attacks have actually risen to this level.”
“Billions of years ago, when he fought against True Saint Yanhuo, he would still be suppressed by the opponent. In the blink of an eye, he might be more terrifying than True Saint Yanhuo..”
“The speed of progress is terrible.”
“The original number one genius, he is truly worthy of his name." The true saints and holy saints from all forces were quite shocked and sighed..
“In terms of material defense, billions of years ago, he was ranked among the top ten or even the top five true saints. Now that the eternal divine body is perfect, it will only be more terrifying. He can definitely hit the top three or even the first place in material defense..”
“indeed！”
“True Saint's material defense is number one, he has hope！”
“In terms of attack, it is definitely among the top ten. So, how high is True Sage Wu Yuan ranked? top ten? Or the top five? "You Zhensheng raised a question.
“Definitely can break into the top ten.”
“But it’s hard to say whether it ranks among the top five..”
“Look! This time when the tenth Ruins Realm opens, many powerful true saints will appear and burst out in strength. It is destined to be a storm. When the Ruins Realm ends, there will probably be several Holy Saints born in the Endless Realm." Powerful people from all sides argued endlessly..
But there is no doubt that with Wu Yuan's strength, it is certain that he will reach the top ten of the True Saints List..
but.
Perhaps it was because the Tenth Ruins Realm had just opened and the battle between the top true saints had not yet begun. Therefore, it was rare that Wanyu Tower did not immediately update the ranking of true saints..
……
The Ninth Ruins Realm, an inconspicuous void.
A man in a blue robe, with extraordinary bearing, elegant and free-spirited long hair, is strolling leisurely.
He seemed leisurely, but his speed was astonishingly fast. He easily broke the limit of Yuhe's rules and reached a thousand times the speed of light..
Such speed is terrifying in the Ninth Ruins Realm.
he！
He is the True Saint of Luanhai. He has experienced many bloody battles and finally stood at the top of the True Saint of the sea. He is recognized as the "No. 1 True Saint on the True Saint List"..
“Haha, interesting and interesting.”
“With such strength in just a few billion years, this True Sage Wu Yuan will probably reach the pinnacle of sainthood soon, and he may not even be able to match the Great Emperor in the future." True Sage Luan Hai smiled slightly: "You have to hurry up. Time, hurry up and bully him.”
“Otherwise, when he breaks through, he will only be ravaged by him..”
“There are also Yunsheng, Yinyu, Dongyi, Mengguan and the others... Haha, they all ravaged them one by one before they broke through..”
His mentality is very good.
As a direct disciple of Emperor Yantuo, he has always targeted Emperor Yantuo..
“Chaos source heart？”
“Tsk tsk！”
“According to the Master, there are great secrets behind the eight dangerous places in the Endless Sea... What are the secrets behind the Nine Ruins of Chaos, no, I should say the Ten Ruins of Chaos.？”
……
more than ten years later.
call! call！
Wu Yuan and True Sage Tianpeng easily broke through the rift in time and space and arrived at the Tenth Ruins Realm..
What caught their eyes was the endless dark void, like a ruined universe..
The dim void, the ferocious cracks in time and space.
In the endless void, there are vaguely huge stars.
Some stars are very dazzling, like stars, giving people a sense of endless vitality.
But most of the stars look very old and full of vicissitudes of life..
“The suppression of the Tenth Ruins Realm is even more terrifying than that of the Ninth Ruins Realm! "Tianpeng True Saint couldn't help but said: "However, I haven't seen a single True Saint..”
“The true saints who came in first are probably scattered in all directions, searching for their own treasures." Wu Yuandao.
According to Wu Yuan's estimation, except for the strong men of the Abyss Alliance, there are very few true saints from other major forces who have broken in..
They are those who entered very early.
“Tianpeng, you have to be careful in your next foray." Wu Yuan said: "This tenth ruin realm is no better than the first nine ruin realms. It is completely unfamiliar. There is no information in the witch court. We are already the first batch to break in..”
“We don’t know what kind of killing formation or special ruin spirit there is.” Wu Yuandao.
“I understand." True Sage Tianpeng nodded and said, "We are the ones who opened up wasteland..”
open up wasteland！
Like the first nine major ruins, over the long years, one true saint has traveled through the other, gathering together to form a large amount of information..
Latecomers can avoid most dangers as long as they rely on intelligence.
For example, if Wu Yuan didn't know about the Nine-Chen Heavenly Tree when he first encountered it, he would probably just think it was a place of treasure. Once he broke in recklessly, he would be killed by the terrifying Ruins Spirit..
In the Tenth Ruins Realm, everything is unfamiliar. In a sense, we need pioneers like Wu Yuan and Tianpeng True Saint to provide information for the later True Saints of the Witch Court..
“OK.”
“I always take advantage of the witch court, this time, I will be a pioneer." Wu Yuan felt quite calm in his heart, and since he was powerful, he had to admit the corresponding responsibility..
Now in terms of strength, he is the number one true saint in the witch court, probably no less than the true saint of the East Wing..
Naturally, we must admit corresponding responsibilities.
“Wu Yuan, I thought about it, why don’t we just separate and go on our separate ways." Tianpeng Zhensheng suddenly said.
“separate? "Wu Yuan was stunned for a moment, thinking deeply in his heart..
“You are extremely powerful, and it will be extremely safe to follow you." Tianpeng Zhensheng smiled and said: "But it is precisely because you are so strong that even the secret techniques of long-distance attack are so terrifying... I am completely a burden when I am with you. Can't help you with anything.”
“Then, it is better to separate." Tianpeng Zhensheng said: "And if we attack separately, we can explore more areas faster. If we need support, we can just send messages to each other..”
“good.”
“If you want to go separate ways, I have no problem with it." Wu Yuan smiled lightly and said, "Maybe you can get double the harvest..”
“Then I will take the first step." Tianpeng Zhensheng handed over his hands and left quickly..
The sight of Tianpeng Zhensheng is far away.
“Break out separately？”
Wu Yuan shook his head slightly and said secretly: "I'm afraid, Tianpeng Zhensheng is worried about encountering a valuable treasure and won't fight with me..”
With the strength of Tianpeng True Saint, he can protect himself enough. When facing the top ten strong men on the True Saint List, he is sure to protect himself..
He came here for the important treasure. If he and Wu Yuan met the source of chaos together, would they be able to compete with Wu Yuan?？
People are all selfish.
Wu Yuan knew this very well and was unwilling to point it out..
“That's fine, I'm more free to wander alone." Wu Yuan was very calm, and following his vague feeling, he quickly chose a route to explore..
……The tenth ruin realm is huge and vast.
At the beginning, the areas Wu Yuan explored were all the areas that the True Saint had already searched..
So the gain is small.
But decades later, Wu Yuan quickly became 'rich' through the route he chose..
Obviously, the Tenth Ruins Realm is too vast, and no one has passed through most of the areas..
“These plants are all of the eternal level and can be used to refine eternal level elixirs.！”
“An incomplete middle-grade innate spiritual treasure? receive！”
“This star? This is not a star. It is an abandoned war fortress. If it is refined again, its value may be comparable to that of a low-grade innate spiritual treasure..”
“This palace is also a treasure! All collected！”
“What a huge vein of Chaos Adamantite! ! Sent! "Wu Yuan was quite excited and frantically collected the treasures..
Although most of the treasures are of very low value, they are only worth a few points or dozens of Xuanhuang merit points..
Occasionally, some treasures worth tens or hundreds of thousands of Xuanhuang merit will appear..
But Wu Yuan doesn’t dislike it at all.
Secondly, I can’t stand the fact that there are too many treasures in the Tenth Ruins Realm..
In just four thousand years, Wu Yuan collected treasures worth hundreds of millions by picking up rags along the way..
“The speed of harvesting wealth in this way is no less than killing, and it is much safer." Wu Yuan was quite happy..
You know, before he spent billions of years in the Ninth Ruins Realm, his gains were not as good as those in these thousands of years..
certainly.
Wu Yuan knows.
This is because I can fly so fast that I can gain so much.
Those ordinary True Saints and peak True Saints who entered the Abyss Alliance may not have gained so much, but at least they have gained millions of Xuanhuang meritorious deeds..
Secondly, it is strength.
“In these thousands of years, I have only encountered two true saints. They both stayed far away and no conflict broke out." Wu Yuan said secretly: "But I encountered a lot of dangers along the way..”
It was too unfamiliar, and there was no information provided, so Wu Yuan could only force his way in..
Wu Yuan broke through several killing formations with his absolute strength..
The most dangerous time was when I encountered a strange and unpredictable ruin spirit, which was in the shape of a river. Its strength was terrifying to the extreme, and it had definitely reached the threshold level of the Holy Saint..
In the end, it was Wu Yuan's Law Body and Origin Body who joined forces to escape from the river..
“According to the information, the Abyss Alliance may have lost more than a hundred true saints now." Wu Yuan secretly said: "There are four true saints who have fallen in our Wuting Court..”
Even though forerunners such as Wu Yuan and Tianpeng True Sage provided information, the subsequent True Saints were generally weaker and could not escape some dangers..
It is easy to fall.
As time passed, a large number of true saints poured into the Tenth Ruins Realm.
According to the Wuting's estimation, over the past few thousand years, more than 6,000 true saints have broken into the Tenth Ruins Realm. On the one hand, the 'land reclamation' is almost over, most areas have been initially explored, and most of the easily obtained treasures have been Has been collected by the eternal strong men.
On the other hand, with the large amount of intelligence, the understanding of the Tenth Ruins Realm by the major forces in the region and sea is also rising sharply. The probability of the true saints falling due to the Ruins Realm itself is constantly decreasing..
“Keep exploring.”
“Although most areas have been explored, no one has dared to enter some truly dangerous places." Wu Yuan secretly said: "Secondly, so far, no real treasure has been discovered..”
Like incomplete innate treasures, Wu Yuan collected two pieces.
But Wu Yuan could not find any trace of the incomplete Chaos Spiritual Treasure or the super-large Chaos Fine Gold veins..
I haven't heard of anyone getting it.
There is also a possibility that the Eternal Powerhouse has secretly obtained a valuable treasure, but if he harvested it alone, he would naturally not be exposed..
“but！”
“After all, no one has harvested the Chaos Jade Crystal and Chaos Source Heart yet." Wu Yuan said to himself..
different from other treasures.
Like the emergence of a super-large Chaos Fine Gold Vein, although the movement is large, it is within a controllable range..
Based on the experience of the births of several major ruin realms in the past, when the Chaos Jade Crystal and Chaos Origin Heart were born, the noise was so great that it could alarm at least half of the ruin realm..
I can't hide it at all.
It will cause a large number of true saints to gather together. Not only does it require a certain amount of luck, but also strong strength to seize the treasure..
And even if you want to seize the treasure, you have to be able to avoid the encirclement and interception of a large number of true saints and escape from the Tenth Ruins Realm to be considered a success..
“Walk！”
Wu Yuan chose a direction and continued to move forward in the dark void. In the blink of an eye, another thousand years passed..
There are more true saints entering the Tenth Ruins Realm. According to the statistics from the Witch Court, there are probably tens of thousands of true saints. The Fallen Ruins Realm itself is in danger and there are more than 400 true saints who have fallen in battles..
The tenth ruin realm has been basically explored.
It can be said that the land reclamation stage is basically over. There are already many weaker True Saints who, after gaining huge harvests, began to consciously want to leave the Tenth Ruins Realm..
this day.
“Um? "Wu Yuan is moving forward in the void.
Suddenly, he sensed an astonishing wave of time and space erupting in the void far away..
Rumble~ Terrifying fluctuations in time and space sweep across the void in all directions.
“Heavy treasure！”
“Incomplete Chaos Spiritual Treasure? It's still a super large Chaos Fine Gold vein." Wu Yuan thought in his mind: "It's really weird. During the land reclamation stage, I haven't heard of any important treasures being revealed..”
“Now, such a valuable treasure is born on its own initiative? "Wu Yuan didn't have time to think about it carefully..
Whoosh！
With a movement of his body, he quickly rushed towards the source of the fluctuations in time and space..
