Liu Yu, a graduate majoring in psychology, accidentally traveled through time. His original wish was to become a wealthy family in ancient times just by relying on the knowledge he had learned in modern times.
Unexpectedly, what he traveled to was an extremely dark era, where heroes were divided and bandits were everywhere. In addition, the Japanese and barbarians are also watching from the outside.
The two-legged sheep, the temple with the top of the head, the Wife Presentation Festival, the tomb of sixty-six-year-olds, the leather rugs... Modern man Liu Yu felt that this was simply a purgatory on earth. In order to survive, he had to try to change the world.
But he is not the only one who travels through time. There are demons in the world here, and everyone wants to make the world develop according to their own ideas. However, this world is like a huge poisonous field. In the end, how many people can survive...
