Haojiang City, the city of sex where neon lights and dark alleys intertwine, is both a paradise of wealth and a arena of arena. Chen Haonan (Note: This is an original setting of the same name, not a Hong Kong version of the character). His parents died when he was young, and he was adopted by Uncle Long, the leader of the "Yiqun". He grew up in the shadow of swords and swords, and developed courage and fists. He attaches great importance to love and righteousness, treats his brothers with sincerity, and is loyal to Uncle Long. He is the most capable general of Yiqun and the "Brother Nan" in the eyes of the new generation of people in Haojiang.
However, the world is changing. The old society "Lianxing" has been coveting Yiqun's territory for a long time. New forces are also secretly rising. A storm is brewing that will sweep the entire Haojiang underground world. Lianxing boss Sangbiao was ruthless and set many traps in an attempt to annex Yiqun's entertainment city, dock and other core industries. Uncle Long was seriously injured in an accident, leaving the righteous group without a leader. Amid internal and external troubles, Chen Haonan was ordered to shoulder the heavy responsibility of guarding the righteous group and protecting his brothers.
Relying on his extraordinary wisdom and courage, he united his brothers and launched thrilling contests with Lianxing - from fights in the streets to games in the business world; from ambushes at the docks late at night to negotiations under the neon lights. In the process, there is the passionate help of brothers, the stabbing in the back by betrayers, the silent support of confidants, and the deep persistence of the word "friendship".
