Liu Dayong was an ordinary security guard in the community. After accidentally witnessing a supernatural event, he led out the cat demon Wu Mao Mao. Dayong, who was involved in affairs in the spirit world, gradually grew up in a mixture of humor and fear. He met female detective Song Xiaoyu, retired ghost exorcist Lao Wang, and the agent Qi Ye in the spirit world. The small team began to take on various absurd, weird, but heart-warming supernatural cases. In the process of overturning the two realms of spirit and human, Dayong and his teammates crossed the edge of horror and comedy, supported each other, and slowly uncovered the secret behind the abnormal commotion in the spirit world. The three volumes of stories have ups and downs, echoing back and forth. In the process of solving the crisis in the spiritual world and personal growth, the transformation from "coward" to "hero in the spiritual world" is realized.
