At the bottom of Sword Abyss was sealed the ancient sword venerable from three thousand years ago. Su Wen, a youth who had guarded the stele for ten years, wiped the three thousand names on the stele. On the first night of torrential rain, the sealing stone split open, red sword patterns crept onto his face, and the person who woke up reported his name as Tu Xiao. Tu Xiao wanted to take back his sword using this body, but miscalculated one thing: every time his sword intent split, Su Wen recorded a mark on the stele. On the third day at dusk, Su Wen held down the sealing stone and sealed Tu Xiao along with his sword into his palm. Three thousand sunken swords floated to the surface of the abyss, forming a curtain of swords suspended above his head.
