Delivery to the Emperor

Evelyn's mother is in hospital and there is no money for the bills. Evelyn works as a food delivery courier, and she has found out what her insulated delivery box can do: an ordinary lunch box packed in a palace kitchen a thousand years ago and carried home inside it turns up in the present as a genuine antique. She sells it to cover the most pressing costs. She got into that palace by accident. She had caught her boyfriend with her adopted older sister, gone straight out on a delivery in that state, and crashed. The jade pendant her family had handed down lit up and dropped her, box and all, into the palace of the Everlasting Kingdom. The founding emperor, Elliot, had lost his appetite entirely, and she got him eating again with a pizza, which kept her from being killed for the time being. From then on she goes back and forth between the two eras, carrying a microwave and bottled water into the palace to help Elliot with food problems and with trouble at the front. The two of them grow close. Later Elliot is pulled through to the modern side, and he proves who he is to the people there with his dragon token and the Xuanyuan sword.
