Stowaway for Three Thousand Years

The gods plotted, and the protagonist, who was a chess piece, overturned the chessboard, traveled back in time for three thousand years, and returned to the time of the game's internal beta. This is a real game, where people obtain various magic weapons, elixirs, and cultivation abilities. However, great opportunities are also great horrors. What mankind will face is not a vast universe where humans are the protagonists. Without the care of heaven, everything can only be done by ourselves.
