After losing her job, Jiang Ning unexpectedly discovers that her family's ancestral celadon jade vase can swallow real-world supplies and even send back bloodstained pleas for help from another time and space. On the other side of the vase is Prince Xie Linyuan, who has been driven to the brink of despair by severed food supplies, poisoning, and the ravages of war. At first, she only intends to send him a few bags of grain and several boxes of medicine, but gradually becomes entangled in a crisis threatening an entire city across time and space. He only wants to protect the soldiers and civilians behind him, but gradually entrusts his life and death to this modern woman he has never met. One gathers supplies in the modern world, while the other defends a city in ancient times. Two destinies that should never have crossed paths are now tightly bound together by a single jade vase.
