After the emperor finished reading the letter, he indeed went to the princess's mansion late at night and did not return all night.

In the following days, he was not in the palace.

He took the eldest princess out for an outing.

Upon returning to the palace, he unexpectedly told me that he wanted to secretly bring the eldest princess back to the palace.

This was unreasonable.

But I agreed.

I also assured the emperor that I would not let this news leak out at all.

How joyful the eldest princess was at this moment, and how desperate she would be later.

The princess's mansion was no longer suitable for living in, so to avoid suspicion, she stayed in my palace.

Deep into the night, I could often hear the laughter of men and women.

I sat calmly by the window, reading a book.

Everything should not be excessive, moderation is key, going too far is as bad as not going far enough.

As it was late tonight, just as usual, I had just sat down at the desk when Li Huaiyan's personal eunuch hurriedly came to fetch me.

"Your Highness, something bad has happened, the emperor is vomiting blood."

I closed the book, stood up calmly, and walked towards the eldest princess's room.

There were broken teacups scattered on the floor, and the eldest princess stood aside, on the verge of tears.

"How is the emperor?" I asked the imperial physician softly.

"The emperor is suffering from excessive fatigue. I have prescribed a tonic to nourish him. Once it is brewed, he can take it to alleviate his discomfort."

I waved my hand, signaling everyone to leave.

"You, stay." The emperor spoke in a low voice.

Following his gaze, I saw a palace maid trembling as she held a censer.

"Please spare me, Your Majesty," she knelt on the ground, repeatedly knocking her head.

"Physician, please check what is in the censer," I instructed.

The physician examined it, sniffed, frowned, and hesitated, saying, "Your Majesty, this is red lead incense, also a kind of aphrodisiac incense, but this substance is very harmful to the body."

"Princess, save me," the maid crawled to the side of the eldest princess, wailing.

"You wretched thing, stop making baseless accusations," the eldest princess kicked her in the chest.

The maid endured the pain and resentment, saying, "Since you are unjust, don't blame me for being heartless. Your Majesty, it was the eldest princess who instructed me to secretly light this incense every time you visited. Otherwise, even if I had the courage of the heavens, I wouldn't dare to do such a thing. The eldest princess knew that this incense would greatly harm the emperor's body, but she still used it. She wanted to harm you."

The eldest princess approached Li Huaiyan, trembling, and said, "Brother Emperor, I have been framed, how could I..."

Before she could finish her sentence, Li Huaiyan slapped her.

I ordered the maid to be taken away, then led the others out.
