The ancient immortal Lord {Ling Xuan} was betrayed by his henchmen when he was going through a tribulation, and his soul traveled to the modern age to become a helpless old man. He was also "picked up" and brought home by the sinister girl Su Qiaoxia, and was forced to become a "cheap grandfather". Su Qiaoxiao seems to be well-behaved, but in fact he is full of counter-tricks and specializes in tricking school bullies and hypocritical villains. Facing the street bully who was trying to steal money, Ling Xuan secretly sent a "bad luck charm" with his fingertips; when he met the hypocritical school boy pretending to be a good guy, Su Jiaoxiao backhandedly exposed his dirty information. One man and one old man are playing with the modern world, using fairy tricks to defeat modern villains, and using counter-routines to unravel conspiracies. The immortal grandfather, who is both good and evil, teams up with a sinister girl, causing chaos on campus and on the streets. They are looking for an opportunity to return to the fairy world, but they don't know that a bigger cross-border conspiracy is quietly approaching!
