Lin Xuan, the lord of demons who once conquered the three realms, was stabbed in the back by his best friend and a beauty when he was going through a catastrophe, and his body was completely destroyed. Thousands of years later, he woke up in the body of a "sect's shame" that was despised by everyone. What's even worse is that he discovered that this world is bound by a mysterious [Heavenly System], and all monks have become "players" who must complete "system tasks". And his existence itself is a high-risk BUG in the system.
