Abandoned by her parents, Chloe inherits a run-down grocery store along with a crushing debt. Hidden in the back storeroom is a two-way time portal — straight into a war-torn medieval world. Leopold, a legendary warrior duke, defends the borderlands through endless battles, starved of supplies and medicine, sabotaged by scheming nobles. His brilliance on the battlefield is matched only by the dangers closing in around him. Chloe becomes the lifeline to his world: she feeds the army with compressed biscuits, sugar, instant noodles, canned goods, medicine, and winter gear, pulling them from famine and plague. In return, she sells Leopold’s jewels in the modern world, clears every debt, and builds a fortune.
