Shen Guhong, a swordsman who had retired for three years, was bloodbathed by his fiancée Su Qingxue on his birthday night. The ancestral "Tiangang Sword Art" and 1,200 lives were turned into ashes. He climbed out of the ruins, picked up the broken sword and entered the world again. When he exposed Su Qingxue's demonic identity in public at the martial arts conference, his senior brother Ye Hanzhou drew his sword and pointed it at him. Intelligence dealer Bai Fengming handed over a blood-stained secret letter, and the disfigured saint Liu Ruyan sneered and handed over poisoned wine. The former love has become a mortal enemy, and the mastermind behind the scenes is dragging the entire martial arts world into a blood sacrifice that has been planned for thirty years.
