While delivering food, I accidentally travel back in time and become bound to a cross-temporal food delivery system that allows me to duplicate modern meals using my delivery box. With the army running out of provisions, I save the starving soldiers by bringing out braised chicken with rice and spicy hot pot. I earn the general Xiang Yi's admiration and open a shop in a prime location in the city. Recreating modern delicacies such as milk tea and river snail rice noodles, I soon take the entire city by storm. When enemy forces surround the city, I travel back and forth to the modern world to purchase supplies and resolve the crisis. Yu'er repeatedly frames me, but after the truth comes to light, she is driven out. I continue traveling between the ancient and modern worlds, bringing back supplies to help train the troops. When the Hu forces breach the city walls, my delivery vehicle is destroyed, but I unlock an unrestricted time-travel ability and transport enough supplies to defend the city. Eventually, peace returns to the chaotic world, and the general finally confesses his feelings. A cross-temporal romance, with both hearts choosing each other, slowly begins.
