The sky in Jinggang City is gray, and He Chen is the most dazzling red in the gray. As a well-known demon king in the old city, He Chen acts wildly and believes in fists rather than truth. However, when he picked up a stray dog "Heisha" with a black body and blood-like eyes, his originally peaceful street life suddenly collapsed.
Heisha can not only understand people's words, but also smell the sin and fear deep in people's hearts. It led He Chen into a shocking murderous situation against the top wealthy Zhao family. Zhao Ting, the second young man of the Zhao family, looks like a gentle and gentle son of a high-ranking official, but is actually the "sword holder" who controls the underground order in Tianjin and Hong Kong.
When a wild dog smells the blood of a powerful man, He Chen is forced to get involved in this highly intelligent hunting game. Will he become an abandoned son in the hands of Zhao Ting, or will he overthrow this huge power with the help of Heisha's superpower? In this confusing situation, He Chen used his fist to open up a way out: I am a gangster, but I can play with my life!
