Lin Yichen accidentally enters the world of immortal cultivation and takes shelter in the Forbidden Demon Forest, an isolated place cut off from the outside world. In this forbidden land, untouched by anyone for a thousand years, he unknowingly cultivates all the way to the peak of the Nascent Soul realm, completely unaware of his own extraordinary cultivation because he knows nothing about immortal cultivation. An unexpected incident activates a teleportation array, transporting him to the main hall of the City Lord's Mansion in Xuantian City. His cultivation is so unfathomable that even Golden Core cultivators cannot see through it. Mistaking him for an ordinary mortal with no spiritual energy, they repeatedly humiliate him and drive him away. While wandering the streets, Lin Yichen is taken in by Su Qing'er, a kind-hearted disciple of the Number One Sect Under Heaven, and becomes an outer laborer disciple. Another ten years pass. He diligently works at the sect, hoping to achieve something great.
