After the Jinshan Mountain was flooded, Snake Xiao Qing was sealed by Monk Fa Hai and guarded by the Demon Control Department. Five hundred years later, Li Xiu Ning, who came here to take the talent election exam of the Demon Control Department, stepped into Xiao Qing’s sealing area and broke the seal by accident.

As they grew familiar with each other, Xiao Qing found out about another identity of Li Xiu Ning.
