Did I Get My Hands on a Magical Plant Today?

The title sounds cute, but this is actually an infinite game! I returned after clearing an infinite game. But the real world was shrouded in eerie energy, and all the plants withered and died. If people wanted food and a chance to survive, they had to enter a new game and fight for a slim chance at life. The apples growing on an apple tree blossomed into chunks of meat? A little lotus flower condensed clean water every day? Grapevines grew household goods? Brought to you by the Infinite Game, with quality guaranteed. All the plants brought out of the instances could absorb the eerie energy and give everyone a safe home again. To purify the environment, I still have to work hard today, bashing ghosts in the instances. [Third-person narration, nonsensical logic, male lead, strongest heroine. Enjoy without worry.]
