Xuanyuan Chen, the eighth prince of Daqian, pretended to be stupid since he was a child in order to avoid court strife and became the laughing stock of the royal family. With a marriage certificate, he was given a marriage to Su Qingying, the daughter of the wronged general. This was originally a humiliation, but it turned out to be unexpected. After marriage, he showed his true talent to his wife, and the two formed an alliance. Xuanyuan Chen used "stupidity" as a cover, secretly plotted, stirred up the chaos in the court, cannibalized his opponents step by step, cleared the grievances of his father-in-law, and finally pulled down the prince and the second prince, and aspired to the Ninth Five-Year Plan. This is a counterattack that begins with forbearance and ends at the peak.
