Liu Qingqing was an abandoned daughter of the Liu family with a Yin evil body. She broke into the ruined temple at the Changpu Reservoir and broke through the Hu family. Hu Fangyun sacrificed blood to open the Yin door, but blocked it with the Qingmu Transformation Technique. Later, he looked for Li Chenzhou, a disciple of Shaoyang, and learned that the Hu family had colluded with the Yin Ghost King to use pure Yang blood to open the Xuandu City through sacrifices of thousands of souls. The two team up to break the crisis in the earth, find the Bai family's immortal sect, and reveal the secret of the corpse demon buried in the immortal tomb, with the help of the craftsman's sect. In the end, Liu Qingqing awakened the bloodline of Xuandu's gatekeeper, and she and Li Chenzhou used heaven's thunder punishment to defeat the Yin Ghost King and prevent Xuandu from opening. After the war, Liu Qingqing refused to be the special envoy of the Netherworld and stayed in the human world. As a flower girl, she protected the peace of the world, realized the true meaning of cultivation in the ordinary, and found happiness in the fireworks of the world.
