Princess Anle poisoned her father Li Xian in order to gain power. Princess Anle is the first child of Li Xian and Webster. At that time, Li Xian was in a state of imprisonment, so Princess Anle suffered a lot when she was a child, which made Li Xian feel very guilty about her daughter. Later, after the death of Wu Zetian, Li Xian became king. He immediately named her Princess Anle and gave her many gold, silver and jewels.

In order to make up for the debts of that year, Li Xian loved Princess Anle very much, and he would try his best to meet the demands put forward by Princess Anle. Li Xian's love makes Princess Anle more and more arrogant and psychologically distorted. She began to be unwilling to be just an ordinary princess. She envied Wu Zetian's prestige after he ascended the throne, so she proposed to be the emperor's wife like her father Li Xian, so that she could inherit the throne like a prince.

This request is really unprecedented. After all, the princess will marry when she grows up and let her be the wife of the emperor. This country will change its surname in the future. Therefore, even Li Xian, who dotes on her daughter very much, disagrees. Instead, she was very angry and scolded Princess Anle. Li Xian's scolding not only didn't awaken Princess Anle, but made Princess Anle bear a grudge against him and have a strong revenge.

The next day, Princess Anle took the initiative to apologize to Li Xian, and then she still showed a naive and romantic look. Li Xian also thought that her daughter might just be confused for a moment, so she was relieved. Soon, Princess Anle entered the palace again and brought Li Xian a snack made by herself. Li Xian was very happy and felt that she didn't love her in vain, but Li Xian didn't know that Princess Anle had poisoned the dessert. After eating them, Li Xian died of poisoning, but in the end Princess Anle didn't get the rights she wanted.
