Zombie apocalypse, order collapses. The biggest existential crisis faced by Lin Xiangyang, a former programmer at a major manufacturer, is not the bloodthirsty monster, but his eight-year-old son who cannot move without a tablet. While other survivors were fighting for food, he was worried about his children's "quality education" in the ruins. Until they meet a group of animal allies who have awakened their wisdom due to the virus-a German shepherd who can build walls with vines, an orange cat who can prepare herbs, and a red panda who is proficient in circuits. Thus, a doomsday survival with a strange style unfolds: using mathematics to distribute materials, using physics to create traps, and using programming to solve crises. Lin Xiangyang gradually understood that on the ruins at the end of civilization, what he had to rebuild for his son was not only a safe home, but also a future worth growing up. This is a survival guide for hard-core dads and the ultimate answer to love and education in the apocalypse.
