Leng Zhao was once the best swordsman in the world, but because of his beloved wife Yu Zheshuang, he was falsely accused of collaborating with the enemy. His entire family was executed. He broke his sword into the snow and vowed to kill everyone who betrayed him in the world. Three years later, he returned to the world in the name of the Demon Lord of the Evil Sect. His sword came out like frost and stained the Nine-Layer Tower with blood. But Yu Zheshuang was not dead. She hid in Xuanyin Pavilion and refined the bone-corroding poison technique, just to wait for him to cut off this relationship with his own hands. When the gentle words of the past turn into sword blades, when redemption and revenge confront each other under the moon, will she exchange her life for his return, or will he use his sword to cut off the rest of her life? When Han Ren broke up with her, he changed his fate against fate, but he didn't know that she had already carved her fate into his scabbard.
