Lin Qingyu, a graduate student in ecology, accidentally activated the family's "Symbiosis Evolution Device", which can establish spiritual links with animals. When he tried to sign a contract with "Xuan Mo," a stray black cat that was smart but suffered from eye problems, he discovered that there was a trace of the genetic imprint of ancient creatures sleeping in its body. This is not a tool of slavery, but a gift in both directions. Lin Qingyu used his solid genetic knowledge and CRISPR technology to repair Xuan Mo's defects and unlock his potential (such as precise editing and repair of his night vision-related genes). He teamed up with Su Wanqing, a caring volunteer from the Animal Protection Association, Professor Zhou Ming, a staid genetic ethicist, and Liang Zhe, a pragmatic community planner, to build a "symbiotic community" step by step, starting from solving the problem of a cat and then mitigating the community heat island effect, advocating equal partnership. Amid misunderstandings, doubts, and the temptation of commercial interests, Lin Qingyu adhered to the concept of "complementary ecological niches and emotional symbiosis" between humans and animals, empowered goodwill with science, and ultimately promoted the birth of the "Urban Spiritual Pet Genetic Ethics Law", building green dream homes full of vitality and warmth in bustling cities.
