In the temple on the border of the Great Yong Dynasty, Chen Mo, an orphan who was eating and waiting for death, accidentally activated the "All Souls Illustrated System". The system requires him to collect rare objects from the world to avoid sudden death. Chen Mo, who originally wanted to lie down, is forced to start a "paddling" adventure - casually saving an injured spiritual beast and being treated as a living god, casually digging up a weed turns out to be a lost spiritual grass, lying down and sunbathing can trigger a secret realm. The more he behaves, the more outrageous he becomes. From being regarded as a liar by mortals to being treated as a guest by immortal cultivators, from a street beggar to the "Lying Ying Immortal" who stirs up the turmoil of the nine sects, he finally reveals the secret that he is the reincarnation of an ancient true immortal, and all of this is just the result of his "casual doings".
