Yu Chengfei, who was once the most ruthless person in Beiyuan City, had already washed his hands and lived a stable life with his brothers Wang Hao and Ye Zhan. Unexpectedly, an anonymous bullet broke the calm and "the viper escaped from prison".
Three years ago, Yu Chengfei personally sent a Yunnan drug lord to prison, but he did not expect that it would leave fatal consequences. Now the enemy is back, and the first one to suffer is his pregnant wife Nan Nan.
"If you touch my family, I will kill you!" Yu Chengfei came out of the arena again and wielded the sword again. But this time he was no longer alone: Wang Hao quickly returned home with Arab mercenaries, Ye Zhan mobilized the black and white connections across the province, and thousands of brothers were ready.
Underworld pursuits, police investigations, betrayals... Amidst numerous crises, Yu Chengfei discovered that there was an even more shocking conspiracy behind this revenge.
When the war spread to the kindergarten, Yu Chengfei held his son with a fierce look on his face: "Since the rivers and lakes won't let me go ashore, don't blame me for the bloodbath in Beiyuan!"
