Lin Xiaole, a loser student at the Magic Academy, was accidentally bound to the "Urban Cultivation Sign-in System". By signing in at a corner of the city every day, he can receive cultivation rewards such as elixirs, talismans, and air control skills. On the surface, he looks like a funny rookie, but in fact, he secretly uses his abilities to treat terminally ill patients, crack metaphysics scams, and crush fake masters, attracting the attention of hospitals, capital, and secluded cultivators. When the richest man knelt down and begged him to save his son, the police asked him to solve the mysterious case, and the cultivation sect sent killers to silence him, Lin Xiaole realized that what he signed was not the city, but the recovery node of the entire cultivation civilization. From a scumbag in magic who was ridiculed to an "urban hidden immortal" who bowed his head to the global cultivation forces, he used the sign-in system to rewrite his destiny, but he always pretended to be stupid and dumbfounded, just because he felt that pretending to be a pig and eating a tiger was the most enjoyable way to cultivate.
