In Tianqiong City, where neon lights flash, technology and martial arts coexist, there are two completely different worlds.
The outer world is a steel forest where mortals live in order, while the inner world is a dark jungle where Yuanli warriors run rampant and the weak eat the strong. The rules are written by the strong.
Chu Yunshen is a feared underground overlord in this world, codenamed "Yan Jun". He single-handedly established an underground order that no one dares to challenge, and his name can silence the most fierce warriors.
However, in the outside world, he is just a taciturn and gentle bartender in the "Forget River" jazz bar. He seems to be powerless and leads an ordinary life from nine to five.
When Qin Wanyan, the elite female guard of the Zhenwu Division who is responsible for handling extraordinary events, walked into this bar for a bizarre case of missing warriors, the gears of fate began to turn.
One is a sharp blade that walks on the tip of a knife and vows to maintain the order of the world.
One is a king who lives in the center of darkness and creates peace through killing.
When she began to doubt this "ordinary" bartender, when his peaceful life was torn apart bit by bit, a storm sweeping the entire city was quietly brewing.
What is the purpose of his hidden edge to protect? And where will the truth she seeks lead to?
