Cheng Fei was originally the "leg pendant" of the strongest zombie on Star A. He was involved in the time and space vortex during the battle between the Zombie King and the superpowers. He traveled to the northeastern countryside in the 1970s, lost his combat power and was covered in dirt. Cheng Qiuxia mistakenly thought that she was adopted by a "silly girl", doing laundry and cooking. Cheng Fei still drooled when seeing blood, but could only chew vegetables. He was often chased by dogs, chased by chickens, and fell into pig pens and sauce vats. He used his special sense of smell to identify human traffickers, and accidentally cured the dying uncle after being bitten. There was a rumor in the village that "one bite can cure the disease." Cheng Qiuxia made a rule of "biting three people a day" and acted as a manager.
