Li Wu Jiu struggled to rebuild the "Nine Revolutions of Blood Gang" in his ten-year-old body. Every night, his meridians were like cracks, and he only relied on killing to activate memory fragments. On the surface, Bai Suyuan cooperated with Xie Qianshuang to hunt him down, but in fact, she used his blood to refine the secret detoxification recipe to try to wake up her sleeping sister. Venerable Iron Bones pretended to suppress evil and secretly extracted the evil power from Li Wujiu's body to repair his broken body, causing the righteous sects to go crazy one after another. The child elder in the ghost market used the 'child body life-sustaining medicine' as bait to lure Li Wujiu deep into the old place of the demon sect, revealing that eight sects had conspired to destroy the demon sect, just to steal the true secret of Blood Gang. Before his death, the mute boy Ah Qi drew a map of the truth with his blood. Bai Suyuan was shocked to discover that her sister was the only surviving 'Human Gu Mother', and Li Wujiu's body was filled with the blood of the demon sect leader who had been taken away. Xie Qianshuang cut off the sword sect's talisman and went into the barren valley alone to save him, but the Iron Bone Master threatened the lives of all the sect's disciples. Li Wu Jiu took the initiative to speak for the first time: 'Everyone I kill deserves to die. ' The Blood Gang finally reached its ninth turn, the sky cracked, and the foundations of the eight sects were shaken. Whose sword is the real 'righteous way'?
