In the tenth year of Jiaqing, Prime Minister Situ Lang attempted to rebel. The emperor, regardless of brotherhood, ordered the entire Situ family to be executed. More than 300 members of the Situ family disappeared overnight, except for his son Situ Fengguo, who was nowhere to be found. In the twelfth year of Jiaqing, the Holy Emperor passed away, and Prince Li Buyun ascended the throne. He devoted himself to eradicating the roots, but Situ's son was still missing. When the prince succeeded to the throne, his reign name was changed to Tianyuan. In the third year of Tianyuan's reign, Lan Rushui, the courtesan in Kyoto, refused the emperor's gift and left the city resolutely. It was rumored that Lan Rushui fell in love with a man of the same sex, and this person was also the only true love of Su Cheng, the general who protected the country. What's even more strange is that this woman who overturned history was named Situ Fengguo.
