Global Survival: I Rule the Universe with Food

[Transmigration + tower defense + worldbuilding + lord + hoarding + adorable male lead] Bai Yexiao woke up one morning to find herself dragged into another world where everyone had to survive the apocalypse. Every night, monsters spawned and attacked the shelters. Even her awful ex was there. Afraid her ex and the people around him might recognize her, she lay low, doing her best to survive alone in this dangerous world. Along the way, she took down one monster lair after another and worked her way up to the top of the rankings. She was also the number-one shopkeeper on the store rankings. Every kind of food she sold flew off the shelves as soon as it was listed. Her regular customers ate through their tears of gratitude. Customers: “Miss Shopkeeper, how about I give you my family’s secret recipe? Please stop torturing our stomachs.” (It tastes awful, but they still want to buy it.) Ex: “The number-one girl is my girlfriend.” The little hedgehog kicked her ex flying. “Shoo, shoo! She already dumped you. Now she calls me Baby every day, says I’m adorable, and wants to kiss me.” Bai Yexiao, who was raising the little hedgehog Charlie as her son, was horrified! The day she met Charlie, Bai Yexiao had simply thought the little hedgehog was cute and wanted to tie it up and take it home as a mount. The antisocial, introverted little hedgehog: “You’re the cute one. Your whole family is cute.” She thought that if she could just survive one world, she’d be able to return to her original one. But it turned out this was only the beginner’s trial. There was a second world, a third, a fourth... Coming in the second world: adorable, soft and cuddly animal subjects + ugly, vicious insect monsters
