Ten years ago, he was the feared "Dragon Blade" Li Xuan in the underground world. The "Dark Pavilion" he established single-handedly swept across the world, but was betrayed by his most trusted brother and lover. Not only did he lose everything, but he was also imprisoned with heinous crimes. Ten years later, the iron door of Jiangcheng Prison slowly opened. Li Xuan was wearing a prison uniform that had been washed away, but his eyes hid an all-devouring edge. He was released from prison this time only for two things: one is to make the people who betrayed him pay with blood, and the other is to find his long-lost sister who is now in trouble. But as soon as he stepped into Jiangcheng, he discovered that the city had changed. His former enemies had transformed into business giants and powerful figures, and his sister was being involved in a dark deal. Faced with obstacles and murderous plans at every step, Li Xuan relied on his tenacity and extraordinary skills honed in ten years in prison to regroup his old troops and engage in fierce confrontations with new enemies and old enemies. He used thunderous means to clear away obstacles, and in the midst of swordsmanship and business war intrigues, he tore apart the dark veil of Jiangcheng step by step. Not only did he want to regain his own glory, but he also wanted to carve out a bright path for his sister and those who were loyal to him in this chaotic world.
