Xu Shan, an advertising employee, is transported to the world of immortal cultivation and becomes a useless outer disciple of Xinglan Sect with an inferior spiritual root. While everyone else painstakingly cultivates immortal swords, his cheat is a mysterious green seal that can produce all kinds of absurd rule-based magical treasures. From a chef-god towel to a time-stopping subway train, each seemingly ordinary object conceals an unreasonable power governed by its own rules. He establishes an academy and launches marketing campaigns in the cultivation world, using modern ideas and bizarre magical treasures to outwit powerful figures. With one outrageous stunt after another, he rises from obscurity and turns the entire cultivation world upside down.
