The good-for-nothing disciple Shen Wujiu had his sword broken in public during the sect competition, but he pulled out the demon sword Duan Cang left behind by his ancestor, and instantly the demonic energy surged into the sky. The genius swordswoman Bai Zhaoxue was ordered to hunt her down, but she heard her father's dying whisper in the sound of the sword. The law enforcement elder, Elder Mo, secretly lays a net, the iron-skeletal monk uses his remains to build a Buddhist formation, the swordswoman Liu Jiuniang burns incense and offers sacrifices to the sword tomb every night, and the deposed senior brother Zhou Bugui is dragging the entire world into a bloody storm that subverts good and evil. The demon sword is not a demon, and the truth is not dead. When the sword comes out, the world will turn upside down.
