The protagonist Ling Mo travels to the world of immortality and is bound to the "Invincible Self-Discipline System". The system forces him to perform various death-seeking behaviors in order to maintain his invincibility (or obtain rewards). In fact, Ling Mo already had the highest combat power in this world when he traveled through time, but he didn't know it, and his behavior was always imagined by others as a master's demeanor.
