My father, Li Shimin, requests Your Majesty to become the Retired Emperor.

Li Chengan was also very angry when he saw this.

He wondered how Xu Hui could do such a thing.

How could you write this letter?

It seems that Xu Hui has a deep misunderstanding about her mother.

The Empress Dowager was kind-hearted, upright, and very friendly to the concubines in the harem.

Even if the palace maids made mistakes, they would be treated leniently.

She is always approachable and kind to those around her.

As for the claim that the empress dowager seized power and promoted her relatives, that's utter nonsense.

Because, on several occasions, when the Emperor wanted to promote Changsun Wuji to a higher official position, the Empress Dowager absolutely refused.

However, Changsun Wuji could understand, and for this reason, he also resigned from his official post and stayed at home to compile the "Zhenguan Code".

Li Chenggan suppressed his anger and said to Empress Zhangsun, "Mother, don't take these things to heart. Your health is the most important thing. What will happen if you get sick from getting angry?"

Empress Zhangsun sighed: "I have always known that it is not easy to survive in this palace, so I am always careful and walk on thin ice."

But I never expected Xu Hui to attack me like this.

No wonder she moved to the south of the city; it turns out she wanted to use this method to distance herself from the matter, as if she had nothing to do with it.

She seemed so quiet; I never expected her to be so thoughtful.

Empress Zhangsun said a few more words, then coughed again, her face turning pale.

Li Chenggan quickly advised, "Mother, you should rest."

Don't think about anything right now, just focus on getting better first.

Empress Zhangsun nodded: "I understand. You shouldn't tell your father about this. If he finds out, the investigation could implicate many people and cause unrest in the palace."

Upon hearing this, Li Chengan was deeply moved, thinking to himself that even at this point, his mother was still considering others.

After returning to the Eastern Palace, Li Chenggan was in a very depressed mood.

Just then, Su Wan came looking for him.

After Su Wan entered, she noticed that Li Chengqian's complexion was not good, so she asked, "Your Highness, how is your mother's health?"

Li Chengan then took out the letter and handed it to Su Wan.

Su Wan frowned upon seeing this.

She read the letter three times, then asked, "Your Highness, do you really think this letter was written by Xu Hui?"

Upon hearing this, Li Chengan was taken aback: "You mean, this letter wasn't written by Xu Hui?"

Su Wan looked at the letter and said to Li Chenggan, "This letter is indeed flawless. The handwriting is almost identical to Xu Hui's."

However, I have seen Xu Hui's handwriting; I have paid attention to it before.

When Xu Hui writes her name, she emphasizes the dot on the lower right side of the character for "heart" (心).

When Li Chengan heard her say this, he looked closely and realized it was true.

Xu Hui does indeed have this writing habit.

Li Chengan rested his chin on his right hand, wondering if this letter was not written by Xu Hui.

So someone framed Xu Hui. But who is this person?

Thinking of this, Li Chengan felt a tremor in his heart.

He asked Su Wan, "Are you sure this letter wasn't written by Xu Hui?"

Su Wan nodded: "This letter was indeed not written by Xu Hui."

First, the handwriting doesn't match. Second, Xu Hui's wording is very elegant, which doesn't match the tone of the letter.

Therefore, I can conclude that the person who wrote this letter was not Xu Hui, but someone else, most likely someone from the inner palace. This person was scheming to bring down Xu Hui and kill your mother.
