Qiu Yingying was bought from one cage and placed in another. Chen Mo paid 100,000 yuan to buy her from human traffickers and put her to work as a non-staff member in the Demon Division. She had no combat skills, so all she could do was run errands, handle odd jobs, and deal with the cleanup. But she endured. She endured the terror of seeing a demon for the first time, the night she was nearly lured away by a disguised demon, and mission after mission in which she came within a hair's breadth of death. Gradually, she grew accustomed to the cruelty of this world. Until that night, when a Level Seven demon appeared in an abandoned subway station and devoured everyone who went inside. Chen Mo led the whole team in, then they vanished one by one: Old Zhou was dragged into its mouth by a tentacle, Han Xue was pulled into the darkness, Lin Xiaoguang's scream cut off abruptly, and finally Chen Mo. Before he was dragged away, he said only two words to her: "Run!" She was the only survivor. As she crouched in the darkness, trembling, a voice asked her, "Do you want to live?" Clutching an old chainsaw she had found somewhere, she started the engine and charged at the darkness that had devoured everything.
