Dragon City is an inland metropolis famous for its heavy industry and complex Jianghu forces. During the day, the towering chimneys spit out thick gray smoke, and the torrent of steel rushes along the city's main artery, highlighting the city's ruggedness and vitality. And when night falls, neon lights outline another bizarre scene. In the dark corners of the city, all kinds of desires and sins are like wild weeds, spreading wantonly on the edge of the law.
Xiao Zhengfeng, captain of the Special Service Brigade of the Criminal Investigation Detachment of the Municipal Public Security Bureau, was punching the sandbag in front of him. Sweat soaked his black vest, outlining his angular muscle lines. He was about thirty-five or sixty years old, his eyes were as sharp as knives, and there was an untamable anger between his brows. Xiao Zhengfeng is a well-known "lone wolf" in the police force. He has a fiery personality and hates evil. His case-handling methods often wander on the edge of discipline. However, he has repeatedly solved strange cases because of this. He is the most troublesome evil star for the evil forces in Dragon City. His fighting skills have reached a state of perfection. It is said that he once subdued more than a dozen armed gangsters with his bare hands.
