Zhang Fan, a deliveryman who was kicked out by his ex-wife, dreams of a doomsday world eroded by black fog every night. Lin Ran, the cold-blooded commander there, relied on the ingredients he picked up during the day to deliver food - the egg fried rice he made could purify the black mist, and the braised pork could repair genes. On the day of his ex-wife's wedding, Lin Ran was dying to protect the base and urgently needed a "Light of Life" main course. Zhang Fan carried the insulated box and crossed the blocked door to propose to his ex-wife: "The order address is in another world." From then on, the back seat of his eDonkey carried the fate of the two worlds, and the kitchen was his place of worship.
