Ten years ago, the Jinling Lu Mansion collapsed overnight, and everyone in the family was massacred. The young master of the Lu family, Lu Jiuxiao, escaped with his life and lived in anonymity since then. Ten years have worn away the youthful spirit, and the former master has transformed into a decisive and powerful young warlord, returning to the turbulent Shanghai. This ten-mile foreign land is a mixed bag of good and bad, with warlords and gangs running rampant. The five major families who participated in carving up the Lu family's property and planning the massacre are now all powerful and famous families in Shanghai. Lu Jiuxiao worked step by step, vowing to settle the blood debt and make all enemies pay the price. The road to revenge is unexpectedly full of twists and turns. He reunites with his childhood sweetheart and his fiancée, who has actually married into the family of his enemy's heirs. She also holds the core evidence of the murder case. The entanglement of old loves, the superposition of new enemies, the competition for power among various warlords, and the fighting between rivers and lakes gangs, put Lu Jiuxiao into many difficulties. He peeled off the cocoon in the undercurrent, making a difficult choice between personal hatred and the righteousness of his family and country. He used the power of the governor and iron-blooded methods to set off a revenge storm that swept the entire Shanghai beach, and gradually uncovered the unknown and shocking conspiracy behind the massacre of the family ten years ago.
