Medicine slave Shen Zhe climbed out of the poisonous pool and cut off the sect's shackles with one sword. Chu Xiu, who betrayed him in the past, now uses erysipelas as a bridge to get closer to the blood-stained truth step by step. Bai Jin controls the black market, Su Tang secretly burns the directory, Mo Wujiu uses his mouth as a knife, and Iron Throat uses his life to store scriptures - when the poisonous sword is unsheathed, all the grievances and hatreds in the world will collapse in the blood mist. They are not knights, but living people who have been made into swords. Every step they take is an echo in the mountain of corpses and sea of blood. Shen Zhe wakes up in a pool of blood and practices with the fragments of the Veins-Eating Sword Sutra, intertwining a legend about betrayal, revenge and redemption with Tiehou, Chu Xiu, Su Tang and others.
