Wilderness reclamation + farming + food + business + adorable pets + sweet romance + apocalypse + infinite worlds
After a global nuclear explosion, humanity moves into a twelve-level underground city, where the poor on the bottom level aren't allowed fresh food.
Lin Maisui, a timid girl with a sharp tongue and cooking skills second to none, transmigrates here with only a radiation-injured puppy for company.
Luckily, she has a System: even poisoned soil can grow all kinds of supplies! While everyone else gnaws on bland compressed rations day after day, I grow vegetables, stockpile food, and eat meat at every meal, making the whole slum drool!
She gradually clears new land, slowly builds up her resources, runs a little shop, gets rich, and charms all the handsome men. At the same time, she sets out on a culinary expedition through the twelve underground levels to find a cure for her beloved puppy.
