Xu Huai's colleague from the Third Division of the National Security Special Protection Department. He is nearly 1.9 meters tall with an imposing appearance and a strange snake-shaped tattoo pattern below the corner of his left eye. Although he looks fierce, he is actually easy to talk to. He has a black snake that he refers to as his son, which has romantic feelings for Xu Huai. Fu Cang is dedicated to his job and came to help Xu Huai when he heard about trouble with his commission.
