Modern delivery station manager Su Xiaoman time-traveled to ancient Great Yong, and right at the start was framed by her wicked stepsister and locked in the woodshed. Relying on five years of delivery experience, she escaped the Marquis's Mansion, founded the Su's Errands Post Station in a dilapidated shop in the west of the city, and used modern delivery management thinking to carve out a world in Great Yong. From breaking a hundred orders a day to securing military grain delivery, from a street-wide joint defense post station to receiving an official plaque personally bestowed by the emperor, she not only ferreted out Marquis Yongchang who colluded with the enemy and betrayed the country, but also won the sincere heart of Prince Jing, Xiao Heng. When the return system lit up, she chose the ten thousand lights of Great Yong, side by side with her lover, opening post stations all across the country—this delivery champion became the "Delivery Queen" in ancient times.
