Xu Xian traveled through time and became the brother-in-law of the Prince of Chu. He wanted to continue his life as a playboy, but found that the East Palace was poor and surrounded by political enemies. In order to protect his sister and brother-in-law, he changed his name to "Xi Yi'an" and founded the "Yongxing Escort Agency" in partnership with the emperor "Zhao Guang" who visited privately in Weibo. He also launched "Xu's Candy" and made money every day. While dealing with the Jiaofangsi, the court, and the market, he had emotional entanglements with many women, and finally exposed the conspiracy of the remnants of the previous dynasty, helped the emperor eliminate internal troubles, and consolidated the crown prince's throne. Xu Xian became the "invisible god of wealth" of Chu State.
