Cheng Ning, a wild child picked up by a Taoist master, only wanted to lie down, but was dragged by the master to hunt ghosts in the rivers and lakes. When she first entered the supernatural world, she was extremely frightened and unfamiliar with her skills. When faced with the hanging female ghost in red, the ghost-catching props thrown out in a panic were useless. As her experience increases, Cheng Ning gradually adapts, but the villain forces covet supernatural resources and continue to secretly destroy her opportunities to obtain resources and grow. Once, Cheng Ning was targeted by a ghost and wanted to be arrested for a dark marriage. The male ghost was so powerful that the master was seriously injured trying to save her. If he cannot improve his strength as soon as possible to kill the ghosts, his master will be seriously injured and die, and Cheng Ning will lose his only relative. In the process of fighting various ghosts, zombies, and goblins, Cheng Ning mistakenly believed in the ghosts' disguised goodwill, which put the master in danger. The swinger character betrays the protagonist for profit, causing her to suffer a crisis of trust. But Cheng Ning relied on his tenacity and continued to grow with the help of the system. Although she can protect the world every time she defeats ghosts, her master's injury makes her feel painful inside. Under the time pressure of increasingly rampant ghost activities, Cheng Ning worked hard to break through his own strength, stop the ghosts from wreaking havoc, and protect the world.
