Fantasy apocalypse + rebirth + stockpiling supplies + the uncanny descends
When the Heavenly Dao brought about the end of the world, the spiritual energy across the entire Lingwu Continent vanished overnight. Cultivators became ordinary people who could barely lift a finger, divine artifacts became fire pokers, and elixirs became nutritional pills. Then the uncanny descended.
Lu Yi, the fallen young sect master, was reborn three months before the Heavenly Dao destroyed the world. The first thing he did after being reborn was sell his family's ancestral divine artifact for a fortune in gold coins used by ordinary people, then begin preparing for the apocalypse.
Hungry after becoming an ordinary person? Lu Yi stood with his hands in his pockets, gazing at his countless super grain warehouses, and declared, “I’m not interested in food.”
Unable to beat even a single zombie after becoming an ordinary person? Lu Yi switched from spiritual cultivation to body cultivation. With a peachwood sword in his left hand and black dog blood in his right, he punched the zombie so hard it cried for its mother.
Only now did the people who had looked down on Lu Yi realize that they were the real fools all along.
Holy Maiden of the Skyfire Sect: Give me a bite to eat, and I’ll keep your bed warm.
Ancestor of the Sky Dragon Sect: Lord Lu Yi, please take me on as your underling. I’ll follow you for the rest of my life!
Snobbish fellow disciple: Lu Yi, we’re family! How can you bear to watch us die out here?
Lu Yi smirked and slammed the door shut with a mighty flourish.
“Get lost!”
This kind of book without a female protagonist also has a cuckold plot. It's probably a harem story
