The end of the world starts with only a tricycle food cart? Toxic fog fills the air, and monsters run rampant. While others struggle desperately to survive, modern girl Ling Jing binds a system and opens for business relying on roasted sweet potatoes. A single bite can expel toxins, and attacking monsters even turn into ingredients! The small food cart upgrades all the way, and high-ranking human officials vie to order meals. But when her friend is forced to enter the deadly Kuroda, and a neighboring city is swallowed by a beast tide, a conspiracy that uses ordinary people's lives to "nurture superpowers" surfaces. Ling Jing only wants to be a stable boss, but the hot food she serves has become the confidence of an abandoned city resisting fate.
