He is Chen Yandong, the "Dragon King" who controls the underground order of half the city. From an abandoned baby in the slums to building a business empire with swords and blood, his brothers respect him like a god, and his opponents hate him to the bone. But when his power reaches its peak, he finds himself trapped in the most gorgeous siege - the dragnet set by the police is tightening, the brothers who have followed him for many years have hidden ulterior motives, and even the "weak spot" he only wants to protect has become a sharp knife stabbed at him by others. This is a game about survival and morality, and it is also a hero's last struggle to find a "way back" in the darkness.
