How did princess royal's own daughter die?

In the latest plot of "Swing", a key figure appeared, and that is Xuanyuan Xiao played by Hook. It seems crazy, but in fact it hides a huge secret, that is, the mystery of the life experience of the grandson Wuji. No wonder Wuji was very excited when he learned that he was princess royal, and he was eager to solve the mystery of his life.

So what is the secret of Sun Tzu Wuji? In fact, Emperor Tianquan has long known the life experience of his grandson Wuji. XuanYuanXiao and King De are husband and wife, and they gave birth to Lianer. The King of Germany likes the Queen of Yuan, and the King of Germany and the Queen of Yuan gave birth to the grandson Wuji, who is not the son of Tianquan Emperor.

Due to some people's informers, some empresses in the harem learned the secret at that time, but although Tianquan Emperor knew this, he still insisted on supporting Sun Chang Wuji as a prince, ignoring the words of the empresses, and this scene happened to be seen by XuanYuanxiao at that time. Tianquan Emperor naturally did not allow others to know this secret, so he sent someone to kill XuanYuanxiao to cover it up.

After XuanYuanXiao knew the secret, it was a rude awakening, and he realized why he was Wang De's legally married wife, but he could not get Wang De's love. It turns out that the person I love is Queen Yuan, which is why Xuanyuanxiao always says those words after he is crazy.

However, before Xuanyuanxiao could react from grief, the suitor of Tianquan Emperor had arrived. XuanYuanXiao realized that protecting LianEr is the most urgent thing now. In the pursuit of Tianquan cavalry, XuanYuanXiao took his daughter to hide in the bamboo forest. Hiding in the grass, afraid that her daughter's crying would attract the attention of the cavalry, princess royal covered her daughter's mouth, but she didn't want to take Tian Quan cavalry to set fire to the bamboo forest. princess royal was so scared that she forgot that she was still covering her daughter's mouth. In this way, her daughter died in her arms.
