Biological researcher Ye Fan, due to an experimental accident, travels through time to the 3026 gene-polluted apocalypse, where a virus has turned most humans into zombies. Endowed with space-time symbiotic genes, he can awaken anthropomorphic combat plants. Ye Fan rallies plant partners such as the pea shooter Liu Ruyan and sunflower Xiaokui, establishes a foothold at the Botanical Academy base, fights against zombie forces, and uncovers the tragic past of the zombie emperor Ling Feng. While defending against the attacks of aggregate zombies, he develops a reverse enzyme, purifies the polluted land, heals the infected, and joins hands with survivors to rebuild the symbiotic city of Guiyuan, realizing a new world of human-plant coexistence.
