Doomsday is a cruel experiment by high-dimensional "observers". Lu Yan gained the ability to roll back, at the cost of permanently losing a piece of his humanity every time he died. Thousands of reincarnations burned away his joys, sorrows, and joys, and he discovered that he was the only "patch" in the universe against the invasion. In the end, he must set up a dead end, use his own existence as the spear of paradox, complete this unforgettable act of killing gods, and bring dawn to the world.
