Apocalypse: More Children, More Blessings? But I'm a Zombie!

The red moon hangs in the sky, and the apocalypse descends. Li Haotian wakes from a coma and discovers that he has become a zombie. As he stands there, utterly baffled, a status panel suddenly appears before him: [Ding! SSS-rank ability, More Children, More Blessings, activated!] Li Haotian: ??? Wait, is this for real? I’m a zombie, and you want me to have kids?! The beautiful older girl next door: “Haotian, I’ve run your bath. Hurry up and wash, then change your clothes!” The dashing swordswoman: “Captain, I’ll stand watch tonight. Tomorrow night, you can stand guard over me.” The aloof doctor: “Li Haotian, your genes are extremely valuable. Please cooperate while I take a sample!” Li Haotian finally understood. His mission wasn’t to survive. It was to reproduce, revive the world after the apocalypse, and save all of humanity!
