The Reincarnated Villain Makes The Heroines Tearfully Beg for Forgiveness反派：九世轮回，让女主哭求原谅

So the main plot is that he "rewrites" the memory... That is clear from the description. But not really, somehow the memory he writes and shows them is, in fact, what truly happened. So, everyone that saw his memory realized that he was actually their protector, except for the original novel's MC

At the end of the original novel, the novel's MC awakens the soul of previous gods (Author did this randomly because the readers of the original novels kept saying that the MC was a waste and everything happened only because of the strong heroines,) however this also comes as a fluke/twist, our MC using his rewrite system, uncovers that the novel's MC is not the rencarnation of those Gods, or anything similar. But that he is a being from a superior world that kind of stole those souls/essences, and the original Gods are in fact, the previous lives of our MC.

So far, the novel describes all of this in a way that you don't feel that you're being thrown BS at your face, and I love that.... But then! After everything is settled, the MC is revived, the novel's MC is dealt with by the heroines + MC. Our MC realized that one of the heroines (doesn't know which one) is the same as the novel's MC, a being from another world with the aim of conquering our MC's world....

Here comes the twist, he ends up having an or*y with all of the heroines on their first night together and at the end of it, they all turn to light and dissappear. Meaning? All the heroines were beings from another world. So now that other world has their biggest families arguing over who won the "bet" over this lower realm world, and we are told that the "heroines" were soul fragments of important females characters of those big families, and now, although not dead, they are just a secondary soul in the bodies of the original girls, who are at their peak, and have no feelings whatsoever for MC.

So in short, we have 200 episodes seeing the heartwrenching stories of the MC with each girl, only to see him lose all of them right after being reunited. Now the plot changes to him trying to awaken those soul fragments in the bodies of the original girls, before they get destroyed of course.

The dog author who wrote the novel is himself and he has already transmigrate at the start when the upper plane was about to invade the continent. He has the golden finger
named life editor and bound to the continent. If the continent is destroyed, he'll also die. That's why he reincarnates himself nine times to reach the top power like Di Tian from Journey of the Fate destroying Emperor.
