Su Zhao, an abandoned disciple of Xuanshuang Sword Sect, was expelled from the mountain gate with his arm broken, and his blood stained the cold steps. When his former sect members were sitting on the altar, he used his broken body to pick up the cold sword and killed all the elders in the sect with one sword. Jiang Jiuci holds a broken glass sword in his hand, secretly tearing apart the hypocritical mask of the sect; Bai Yan sneaks into the situation with half of the Demon Realm Map, the blood moon is about to rise, and the truth is like a blade. Every time Su Zhao struck with a sword, someone would reveal his guilt; every time Jiang Jiuci made a medicine, he would be one step closer to betrayal. Blood ties, lies, lost swords, demonic abyss... They walked forward on a mountain of corpses and a sea of blood, but the real betrayal may have been buried in their bones on that snowy night that year.
