During the Jiayou period of the Northern Song Dynasty, a strange store - "Wu Qizhai" - was quietly opened on Maxing Street, the busiest street in Bianliang, Tokyo. It does not sell silk, porcelain, rice, flour, grains and oils. It only does one thing: auction information.
The shopkeeper Zhao Yanling, a young man who once did business in the Liao Kingdom, invented a set of "information bidding" tactics that subverted the era based on half of the "Principles of Economics" left by the time traveler. He auctioned off the first oral message of the Liao emperor in the early dynasty, causing civil and military officials of the entire court to compete for it; he released false information to guide Qingyan futures, forcing the Xixia economy to collapse; he even dared to auction "the birthday of the future new emperor" when the kings were fighting for the throne, stirring up public opinion throughout the Song Dynasty.
