Three thousand years later, Demon Emperor Han Mo knelt in front of Dao Yun Peak, looking at the master who loved him the most, and pierced his heart with a sword: "Master, why?" "Because you deserve to die." After being reborn and returned to three thousand years ago, Han Mo found that everything had changed. What was once a close friend has become a life-and-death enemy, and his superior master, Ling Xuewei, the head of Tianjian Sect, actually personally destroyed the entire sect in his previous life. This time, Han Mo decided not to be the waste that was allowed to be slaughtered. He wants to find out the truth, protect the sect, and make those hypocrites pay the price. But when he finally got hold of the truth, he discovered that it was all a chess game that spanned thousands of years. And he was just the most inconspicuous piece on the chessboard.
