Doomsday Savior: I Become a God With My Ramshackle Stall

Su Qingyan and her scumbag husband, Wang Hu, were both reborn before the extreme cold apocalypse. In their past life, Su Qingyan relied on a system inside her bookstore to resell cheap modern snacks to various realms, successfully exchanging them for vast amounts of apocalypse supplies and becoming the savior of the world. Wang Hu's "street food stall" also awakened a system, but he looked down on it and didn't use it, instead relying entirely on Su Qingyan. She gave him her heart and soul, but Wang Hu, consumed by jealousy, pushed her into a zombie horde to her tragic death. After rebirth, Wang Hu seized the bookstore first and dumped the food stall on Su Qingyan. She accepted it calmly, used her engineering knowledge to modify the stall, and accidentally activated its system ahead of time with her blood. She received rewards and unlocked a massive storage space to hoard supplies wildly. Meanwhile, Wang Hu burned all the books in the bookstore and packed it with cheap snacks like instant noodles and soda, thinking he could copy Su Qingyan’s strategy to become the savior. Little did he know that these cheap snacks couldn't be exchanged for supplies from other realms, and he would end up being devoured completely.
