Can't time travelers practice?
Su Hao didn't believe it.
Su Hao traveled to another world and was forced to be a chess pawn. He thought that he was the chosen one to obtain the system, and he was proud of awakening the high-sequence "divine pattern". Unexpectedly, it turned out to be a carefully planned chess game.
The time traveler cannot practice because he has been cursed with a god?
Su Hao didn't believe in this evil, so he had to become a "dual cultivation" wearer who not only had divine patterns but could also practice.
What about being a chess piece? All the consequences of my killing everyone on the chessboard must be borne by the chess player!
