In 4000, Bai Cong, an underground boy, lost his body during a space-time experiment, but unexpectedly became the second personality in the minds of people from different eras. He uses future knowledge to help the host counterattack, from the bottom loser to the business upstart, from the rise of technology to controlling the rules, trying to rewrite the destiny of mankind again and again. But when he got closer and closer to the truth, he discovered that the so-called time travel, rebirth and choice were actually super simulations built by the Sky Consortium. Bai Cong is unwilling to be a pawn in calculations. This time, he wants to break through the prison of computing power and prove that his will truly belongs to him.
