Delivery rider Li Xiangbei is buried in debt, three months behind on rent, and his only hope is the battered delivery box at the foot of his bed.
Every night at midnight, the box pops open by itself and spits out orders. All the customers are historical figures, and their addresses span five thousand years.
Emperor Taizong, Emperor Taizu of the Ming, Guan Yu, Cao Cao, Li Bai, Yue Fei... Some order medicine for diarrhea, some want remedies to soothe their tempers, and others request equipment to boost morale. A modern delivery rider, he travels back and forth through five thousand years of history, delivering food to all kinds of immortals and emperors.
One delivery fee is enough to cover an installment payment.
But these historical figures always find a way to take his orders in unexpected directions.
