In the 17th year of Yongyan's reign, Crown Princess Du gave birth to a pair of twins. The eldest son was named Yan, and the second son was named Jian. His father, Li Fu, became the empress, and established the eldest son Yan as the East Palace, and the second son Jian was named King Zhao. The two sons had very handsome looks, so they had been wary of each other since childhood. Especially after the death of Queen Du, the two brothers became more and more prosperous. The two brothers plotted against each other, and their successor, Lin's son Li Huo, was waiting for them. The situation is difficult, but only one person knows it.
