Abe the Wizard巫师亚伯

this cheat allows him to go to a dimension where time passes 20 times faster, so everyone thinks that his progress is super fast and that he has an incredible talent, but in reality, MC has many years training inside the dimension.

Besides, when he leaves the dimension, his body adjusts to the time he spent inside the "normal" world.

For example, if he goes to the dimension and spends 200 years there (which he never does, he always spends 10 days inside the dimension, which is 12 hours in the normal world) then, even if he has the appearance of someone 200 years old, when he comes out to the outside world, where only 10 years have passed, his appearance will change according to the time of the outside world, so his body will only show as if he has spent 10 years only.

Something MC tried to do was to go to the dimension to heal, and before leaving, his wound was almost healed, however, when he left the dimension, his body adjusted to the time of the outside world and his wound that had already gone through 10 days of healing, regressed to only 12 hours of healing.
