Modern girl Jiang Ning accidentally time-travels to the Aslant Empire with an ancient Greek style, reduced to a hunting ground prey right upon landing. Quick-witted, she impersonates the First Legitimate Princess of Great Tang, overawing the royal family and nobles with her mobile phone, personal storage space, and modern knowledge, and rescues the tragic slave Saien to be her confidant. To raise money to build a ship and return to Great Tang, Jiang Ning exports Chinese cuisine, makeup, and tea art for cultural exchange, selling Tang goods to accumulate capital while maneuvering among multiple factions including the royal family, nobles, and the church. She must conceal her fake princess identity while plotting her survival step by step in a foreign land, staging a power struggle full of comedy.
