Chen Yuan is drinking alone at home after being scammed by a cyber-relationship, when a congenital Dao fetus from the heavenly realm escapes to the mortal world and binds in symbiosis with him. The congenital Dao fetus possesses the law power to enlighten others once, but it is bound by the drunk Chen Yuan with the wish of "never being scammed again." Just as the congenital Dao fetus falls into despair and gives up, Chen Yuan takes out a scam message he received earlier from a little Nezha asking to send money for rescue. After Chen Yuan transfers money as requested, he truly receives Nezha's help, thus starting a path of defying heaven and changing destiny for one man and one fetus.
