The Greatest Warrior of All Time Returns

I was born into a prestigious martial family, yet I was nothing but a useless person with no talent whatsoever.
At least, that was the case until I was trapped in a dream.
[You cannot die here.]
[You can not lose your mind here.]
[Time does not move in this place.]
[You cannot leave until you reach the extreme.]
Geniuses and fools—people say these are two unchangeable truths of the world.
They claimed that I could never enter certain realms because I was a complete fool.
But when a human body and soul are thrown into the extremes of time, they adapt.
[Congratulations. You have reached the extreme.]
Now, it is time to leave.
