Under the bustling city, there is another world hidden - Jianghu. Warriors fly into the sky and escape from the earth, sects control life and death, and ancient rules maintain a fragile balance. But now, the rules are breaking down. Yan Gui, an antique restorer hidden in the market, inherited the last "Zhenwu Si" and a mysterious artifact called "Martial Arts Code". When warriors kill innocent people indiscriminately, when contracts turn into waste paper, when the lost taboo martial arts reappear in the world... Yan Gui must make a "judgment". He is not a martial arts practitioner, but he can deprive the master of his cultivation; he does not know how to box and kick, but he can make the magic skills self-reflect. Because in this city, he is the iron law of the world. However, he soon discovered that his biggest enemy was not the vicious maniacs, nor the defecting master he was pursuing with all his heart, but the "Martial Arts Code" itself, which he relied on for survival. It gave him strength and regarded him as food.
