Fifteen hundred years after the war of gods, the heaven declined. Yang Jian, the God of Erlang, made a living by working as a catcher. One day, Yang Jian was ordered to hunt down a young man, his own nephew.

Thirteen years after Yang Jian (known to some as Erlang Shen) imprisoned his sister beneath a mountain, the once powerful god now scrapes by as a penniless bounty hunter. When a mysterious woman hires him for a new job, Yang Jian soon finds himself chasing down a familiar figure. He must stop Chenxiang, his long-lost nephew, who is in search of the magical lotus lantern that will free his mother, even if it will bring catastrophe. As Yang Jian confronts the actions of his past, he must face a host of dangerous vigilantes seeking the same treasure with the power to alter the balance of their worlds.
