In 2008, the northern industrial city "Linjiang City".
Nineteen-year-old Chen Ye graduated from the city's mechanical and electrical technical school. He has no academic qualifications and only knows how to repair cars and fight. His father went missing due to debt, and local snakes forcibly collected protection fees for the small restaurant his mother ran.
Chen Ye originally just wanted to find a job and pay off his family's debts. But on the night he stood up for his mother, he stabbed a local gangster and dragged himself and his best brothers from the technical school into the rivers and lakes.
They started in a repair shop, collecting accounts, visiting venues, and grabbing business, and gradually established a foothold in the old city. At first, everyone agreed that we would make money together and take care of things together. Later, there was more and more money, the enemies became more and more ruthless, and the brothers no longer wanted the same things.
Some people want to quit, some want to be the boss, some secretly betray, and some left their lives in the coldest winter in Linjiang for a promise they made back then.
Be careful with yourself
