Surrounded by all kinds of beauties, including the cold female doctor, the tyrannical female special police and the pure little Daoist nun, Geng Yun was growing up in pain and happiness.

Advancing from a small police officer to the deputy chief of the police department of the Underworld step by step, he completed the magnificent transition from a little otaku to the most ferocious man in the Underworld.
