On the eve of the Jingkang Incident in the Northern Song Dynasty, Bianjing was peaceful on the surface, but in reality there was an undercurrent. In the court, the Qingliu Party and the Pragmatist Party are fighting fiercely; in the rivers and lakes, the Cao Gang monopolizes the canal trade, and the Shadow Pavilion Killer is like a ghost seeking his life; in the market, Liu Qiniang, a tooth man, travels between black and white, conveying information with coded poems.
Liu Qiniang, a native of Bianjing West Corner Tower, appears to be a broker of business, but is actually a master of intelligence trading. He was orphaned due to party strife when he was young. He was adopted by the Cao Gang and later escaped, adhering to the bottom line of not harming innocent people. She accidentally got involved in a secret conversation between Cui Mingyuan and the elders of the Qingliu Party, and discovered clues to the "Mountains and Rivers Map" - a secret map marking the northern passes, involving a conspiracy of alien invasion.
Cui Mingyuan, the shopkeeper of the Qingfeng Pavilion tea shop, appears to provide a place for literati and refined scholars to have confidential discussions, but in fact he is an orphan of the Qingliu Party and collects information on the party's struggles. He approached Liu Qiniang to test her background. The two went from use to appreciation, and cooperated for the first time in the operation of forging secret messages from the Cao Gang and misleading the killer Zhao Jiulang.
As Mr. Lu's conspiracy to collude with the foreign races in the north came to light, Liu Qiniang and Cui Mingyuan sneaked into Qingfeng Pavilion for secret talks and obtained the Shadow Pavilion assassination list. Cui Mingyuan faces the dilemma of Qingliu Party restoration and northern invasion, while Liu Qiniang sticks to her position in the market. When the two were having a drink by the Bian River, Cui Mingyuan lamented that the world was supported by people in the market. Liu Qiniang laughed and said that the people only brokered business.
In the end, Liu Qiniang used the Yaren network to deliver false information, and Cui Mingyuan instigated pragmatic officials to act separately to prevent the coup. Mr. Lu was exiled, and Zhao Jiulang died in internal fighting. Cui Mingyuan refused to be restored and continued to operate a tea shop; Liu Qiniang expanded her intelligence network and became an underground hub in Bianjing. How little people change the course of history.
