After the spiritual qi revival, strange beasts sleeping in the shadows of cities begin to awaken. Bound by the Human-Monster Coexistence Management Act, they cannot prey on humans at will and must obtain food through official channels. Lu Chuan, an ordinary delivery driver who unexpectedly awakens the “Hundred Flavors Spirit Body,” becomes the only licensed courier able to transmigrate between the human world and the secret realms of the strange beasts without being corrupted by demonic aura. From delivering spicy hotpot to a nine-tailed fox, to finding chilled brain flower for Xiangliu, to stopping Taotie from going on a citywide rampage after being cut off from milk tea, every delivery could cost him his life. As the orders pile up, Lu Chuan discovers that food can not only soothe the strange beasts, but also awaken their lost memories, and fragments of the Classic of Mountains and Seas are hidden within those memories. As the truth behind the break in the ancient myths gradually emerges, the fragile peace between humans and strange beasts teeters on the brink of collapse. To protect the shared everyday world of both realms, Lu Chuan must deliver one ultimate order that no one else dares accept.
