Lin Mo, a young man from the Bone Collecting Village, has carried secrets with him since he was born - the hot piece of weeping jade on his chest, the blurry afterimage of his mother in the mirror, and the strange power that goes out of control every blood moon. When the Tao Eater Zhao Kui tore open the seal of the ancient tomb, he realized that he was the legendary "Chaos Fetus", with the dual bloodline of gods and demons sleeping in his body, which was the only key to breaking the curse of the blood contract.
The puppets in the Abandoned Treasure Cave, the water ghosts in the Forgotten River Palace, the mountain spirits stealing memories in the shadows, the residual eyes of the ancient gods in the forbidden land... He is struggling between the afterimages and the real world. He is surrounded by Axiu, who uses his memories to find a way out, Feng Li, a descendant of the Wind Guardian, and Chen Jiu, the former tomb guardian who protects him with his life. They weaved a path with their sacrifices, allowing him to see clearly the third path of the Chaos Fetus - neither becoming a god nor a demon, but just a "human" guarding the fireworks of the world.
When the blood moon hangs high, the remnant soul of the ancient god awakens in the forbidden place. The rusty iron code of the Eternal Night Army still enslaves people's hearts, and the smoke from the Bone Collecting Village and the sound of children's books have become his strongest armor. The seven soul-suppressing fragments are finally gathered in the hand. What is reflected is not the ferocity of gods and demons, but the obsession of countless ordinary souls:
"The so-called true self is only in blood and fire. I still remember to plant the seeds into spring."
