Zombies Broke Out in Ancient Times, and She Led the Whole Village to Fight Through the Apocalypse

[No CP+growing heroine+ancient zombie apocalypse+infrastructure] Cheng Zhiqing traveled through time! She was in her prime in her twenties, dressed as an old lady in her fifties and had just become a grandma. What's more, I happened to encounter a villager who went crazy and bit anyone in sight. What I thought was an ancient version of poor life turned into an ancient version of zombie chasing? The sky collapse begins! In order to survive, Cheng Zhiqing had to use what he had learned in the real world to pretend to be calm and teach other surviving villagers to survive on the edge of life and death again and again. Kill zombies, build walls, build patrols, rescue loved ones... Cheng Zhiqing grew into a leader little by little, leading the villagers to fight through the apocalypse. Let Zhouzhou Village become a steel barrier and a paradise that everyone envies. (PS: There is no system, the heroine is an ordinary person, the ancient version of the zombie outbreak, welcome to watch~)
