After unexpectedly awakening in a bandit dungeon, Xie Xun unlocks a reincarnation system with one strict rule: he can only restart his life after dying of natural causes. Each reincarnation grants him an exclusive mark that strengthens him. He encounters the spirit dog Xiaotian and, while diligently cultivating various martial arts techniques, travels far and wide to help others overcome their troubles. Along the way, he meets a reclusive Taoist master, gets caught up in conflicts among the martial world, and encounters all kinds of bizarre evil entities. As he steadily accumulates power, he heads to Northern Qi to fulfill the last wish of an old friend. Meanwhile, powerful factions lurking in the county town are secretly plotting, and the road ahead holds even more unknown opportunities and hidden trials.
