Yu Chengfei, once the toughest man in Beiyuan City, had already left the underworld behind and settled into a peaceful life with his brothers, Wang Hao and Ye Zhan. Then an anonymous bullet shattered the calm: “The Viper has escaped prison.”
Three years ago, Yu Chengfei personally sent a Yunnan drug lord to prison, never realizing he’d left behind a deadly threat. Now his enemy has returned for revenge, and his pregnant wife, Nannan, is the first to suffer.
“Touch my family, and you’re dead!” Yu Chengfei returns to the underworld and takes up his battle blade once more. But this time, he won’t be fighting alone: Wang Hao brings Arab mercenaries racing back to China, Ye Zhan mobilizes connections across the province’s underworld and law enforcement, and a thousand brothers stand ready for battle.
Hunted by the underworld, investigated by the police, betrayed by a mole... As crisis piles upon crisis, Yu Chengfei discovers that an even more shocking conspiracy lies behind this revenge.
When the fighting reaches a kindergarten, Yu Chengfei holds his son, a fierce glint in his eyes. “If the underworld won’t let me walk away, then don’t blame me for painting Beiyuan red!”
