That night, the princess built by the prince asked the court painter Yan to paint her portrait, but she was sent by the prince to accompany the king of Qin to drink. Prince Jian, in the name of guarding the border with the King of Qi, mobilized the soldiers and horses of the King of Qin and invited Li Shimin to dinner for the King of Qi in an attempt to get rid of Li Shimin. At this point, Wei Zhi, the counselor built by the Prince, has dug a pit outside the city, waiting to bury Li Shimin. Li Shimin came prepared to expose and denounce the conspiracy of Prince Cheng Jian and Wang Qi Yuanji. After the completion of the Prince, he still refused to give up. He even used the affair between his favorite concubine Dai Ji and Li Shimin to induce Li Shimin to drink poisoned wine.
Li Shimin almost died, so he made up his mind to kill Prince Cheng Jian and Wang Qi Yuanji. Find General Zong, who built Xuanwu Gate for the Prince, and lure General Zong to Xuanwu Gate to coordinate. This scene happened to be overheard by General Zong's six-year-old son. Li Shimin successfully launched the change of Xuanwu Gate, and got rid of Prince Cheng Jian and Wang Qi Yuanji. Before the blood was dried, he went straight to the East Palace to show his mind to Hee Sa, hoping to get Hee Sa's understanding and Hee Sa's body and heart. Strong-willed Su Beiji wants to be a strong woman. Under all kinds of excuses and bewitch, Subei Ji obeyed to make a fifth child on the condition that she didn't kill the prince.
Sun Chang Wuji destroyed the Eastern Palace, but Li Shimin failed to fulfill his promise to Hee Sa. Wei Zhi, the counselor founded by the prince, was fearless in the face of butcher's knife. Li Shimin is so loyal that he hides it under the door. The general zong betrayed the prince and was overwhelmed. Facing the mowgli who came to destroy him, he shot himself.
General Zong helped successfully launch the Xuanwumen rebellion, but Wuji later hacked him to death with the door. Only a six-year-old child survived this robbery by arguing under Xuanzang, the abbot of Jingtu Temple.
After Li Shimin ascended the throne, he wanted to make Hee Sa or Yang Fei queen, but his courtiers opposed him. Because one of these two women is a widow built by the late prince, and the other is the beloved daughter of former monarch Yang Di. The queen's crown is naturally placed on her wife's head. The eldest grandson learned the lessons from the previous dynasty and helped Li Shimin to contain his consorts, which made Sun Chang's infinite political ambition impossible to realize. The veteran minister with outstanding achievements became the prime minister, and even those who were recruited and surrendered were reused. Sun Chang Wuji was very depressed.
Can't let his beloved woman become a queen, Li Shimin can only double his love for Yang Fei as compensation. For the strong-willed Ziji, even if she repents in every way, it will not help. Li Shimin failed to fulfill his promise to kill Cheng Jian's fifth son, which greatly stimulated Xie Ji's spirit and almost collapsed. In her mind, Li Shimin will always be an unforgivable bad king.
After Hee Sa gave birth to Princess Gaoyang for Li Shimin, she was immediately put in limbo.
