Haicheng, a city of sex where neon lights and shadows intertwine. Here, order is the thread of the powerful, while the laws are written with blood and loyalty by the people hidden in the deep gray zone.
Chen Mo, a humble forty-nine boy in the Bamboo Federation, spends his daily life collecting accounts, playing cards, and using his mean mouth to barely maintain a delicate balance amidst the light and shadow of swords. He has no big ambitions, he just wants to make some money safely in this gray area and live like a human being.
However, a seemingly ordinary debt collection task and an inconspicuous mahjong tile, like a stone thrown into a stagnant pool, stirred up a shocking whirlpool that could swallow up the entire city under his already bumpy boat of destiny.
When loyalty encounters betrayal, when passion meets cold conspiracy, when former brothers become life-threatening enemies, Chen Mo is forced to change from a gambler who just wants to "goof around" to a player who bets his life against the entire gray area.
His only bargaining chip is his life and his set of survival rules that he learned from the streets and cannot be put on the table.
"In this gray area, being reasonable will lead to death," Chen Mo lit a cigarette, and the smoke blurred his cynical face, "So, I chose... To give my opponent no chance to be reasonable."
