The four major families in City A (Xiahou, Shangguan, Ouyang, and Huangfu) control half of the country's transportation, medicine, ancient martial arts, and military affairs. They appear to be like one family, but in fact they have their own agendas. Until one day, Lingxi, the youngest daughter of a mysterious Ling family in City S, landed in City A. She had the physique of a "walking koi" and was extremely lucky - she won the jackpot by drinking milk tea, picked up trade secrets while walking, and was able to expose conspiracies even by insulting people.
Xia Houjin: "Lingxi, stay away from me, your good luck will be contagious!"
Lingxi (won the lottery jackpot with a backhand touch): "Oh? Then, Third Young Master Xiahou, do you want to be happy?"
Bai Ruowei (tripped by the trap she set): "You... You all bully me!"
Fourth Young Master (eating melon seeds together): "Miss Bai, today's show is more exciting than yesterday."
