[Multiple heroines] [Forced harem collecting] [Endlessly modifying a broken mechanical heart] [Brutal survival] [Harmless-looking but secretly cunning]
The crisis of a meteorite striking Blue Star was averted, but it marked the true beginning of the apocalypse. Zombies, giant creatures, bizarre beings, and prehistoric creatures made survival increasingly difficult for humanity. After an eerie fog began spreading across the world, Zhuang Fanxin used his unique abilities to modify the technology and machinery of the post-apocalyptic age, setting off on a journey of reproduction.
Nurses, teachers, sisters-in-law, professional mistresses, upperclassmen... They all need to be saved.
When the new era arrived, every Federation citizen hailed Zhuang Fanxin as the Father of the Federation! His contributions to the new era truly deserved the title!
