Carefully opening the envelope, Xiao Ru'an's elegant and vigorous handwriting came into view.

"I can't express my gratitude in words. Today I would like to express my gratitude to the little princess..."

Xiao Ruyu looked at the contents of the letter and tilted his head in confusion.

She pointed at the word she didn't recognize and approached the boy, pointing at it and saying in a baby voice, "Why is this word so crooked... What does it mean?"

The book boy also came over and burst out laughing.

"Little princess, these are engraved flowers on the letter paper, not words."

Xiao Ruyu couldn't help laughing, her dimples slightly raised, "Is this a flower? I thought it was ink that my eldest brother accidentally dropped on it."

The more she thought about it, the funnier it became, and she burst into laughter.

As Eleven walked in from outside the hall, he saw Xiao Ruyu and the servant boy chatting and laughing.

He paused the lotus seed soup in his hand and quietly hid it behind him.

He had an unpleasant argument with Xiao Ruyu yesterday and was just about to make a bowl of lotus seed soup to apologize, but he didn't expect to see this scene again.

Seeing her smiling face and happily chatting and laughing with others, Eleven retracted his hand and his eyes dimmed.

He stood at the palace gate for a long time, and seeing that Xiao Ruyu was only chatting and laughing with the servant boy and didn't notice him, he turned around and left.

Xiao Ruyu felt a gust of wind blowing and subconsciously looked towards the entrance of the palace, but saw no one.

It’s strange, why did I feel like there was someone over there just now?

Thinking that she was hallucinating, she regained her composure and smiled faintly at the servant.

"May I have your name?"

The boy was younger than Eleven, and a hint of embarrassment flashed across his childish face.

"My name is... Nan Xu."

Xiao Ruyu nodded thoughtfully, put the letter away and returned to the hall.

Just when I wanted to show off the contents of the letter to Eleven, I looked left and right but couldn't find any sign of him.

Where did Eleven go?

She called to the maid who was busy working nearby, and asked with her hands on her hips, "Didn't Eleven come to see me this morning?"

The maid stopped what she was doing and answered respectfully.

"Reporting to the little princess, I seem to have seen him just now, but he left before entering the palace."

Xiao Ruyu became more and more confused. Thinking back to what happened last night, she thought that he was in a bad mood and did not delve into it too much.

The imperial physician looked inside.

Doctor Yang was writing a prescription in the house when he heard some noise in the yard.

He looked up and saw that Eleven had come to his yard at some point and was practicing martial arts.

Looking at him, he was silent and looked unhappy.

Doctor Yang walked out of the room and pressed down the palm of his hand that had been practicing. "What happened to you today? You didn't even say hello to your master, but just practiced here in silence."

Eleven lowered his eyes, suppressed the sadness in his heart, and continued to speak stubbornly.

"Master, Eleven just wants to practice well so that he can better protect the little princess in the future."

After saying that, he pulled his hand away and continued to practice his skills in silence.

Doctor Yang circled around him twice, holding his chin in his hand and guessing, "Did you quarrel with the little princess again?"

Eleven paused and clenched his teeth.

"No."

"Okay, okay, if there's nothing, then there's nothing."

"Master, I can't figure out the temperaments of you kids."

Seeing that he refused to speak, Doctor Yang did not ask any more questions. He smiled and left with his sleeves folded.

The moment he stepped over the threshold, some fragments suddenly flashed through his mind.

Why does this scene seem familiar?

Doctor Yang suddenly turned around and stared at Eleven's movements, and memories came flooding back like a tide -

"Did you make your senior sister angry again?"

Under the fruit trees in Yaowang Valley, he smiled and asked the young man who was practicing martial arts silently.

The young man insisted, pounding the stone on the ground as he spoke.

"How dare I make Senior Sister angry? When I get down the mountain in the future, I will protect Senior Sister."

…

All the memories overlapped together, and there was a hint of inquiry in Doctor Yang's eyes when he looked at Eleven.

Before, he had never thought deeply about why Eleven was also able to enter Xiao Ruyu's space.

Why do the past situations seem so familiar?

Could it be that...

An idea suddenly came to Doctor Yang's mind, and he looked at Eleven in a trance.

Could it be that... Eleven is Xiao Ruyu’s junior brother in the previous life!

When this thought came to his mind, he was shocked by himself, but there was no evidence for his momentary suspicion.

While he was thinking about this, the voices of other doctors working with him came from outside the courtyard, interrupting his thoughts.

"Doctor Yang, there is something wrong with this prescription. Please come and take a look."

"I'll be right there."

Doctor Yang withdrew his thoughts and glanced at Eleven thoughtfully before leaving.

"Eleven, practice well."

Inside the Grand Prince’s Palace.

Xiao Ruyu was taking small steps to go find Xiao Ru'an to play, but she saw that the hall was empty.

Nan Xu, who was standing by, saw her and quickly responded.

"Meet the little princess."

She poked her head into the hall and found that Xiao Ru'an was not there, so she asked casually.

"Big brother is not in the palace? Did he go to the academy?"

"Ah?" Nan Xu was stunned for a moment, then asked in surprise, "The eldest prince went to investigate the Lu family's evil party. Didn't he tell the little princess about it?"

He counted on his fingers and pointed at the luggage in the house.

"I came back today to get some luggage, and will go after the Crown Prince in a few hours."

"So that's how it is..."

Xiao Ruyu nodded, remembering that Imperial Doctor Yang seemed to have mentioned this to her a few days ago, but she was sleeping soundly at that time and didn't hear it.

"Then go quickly. I will come to play with my eldest brother when he comes back."

She turned sideways to let Nan Xu pass, and did not forget to add a sentence.

"Don't forget to tell my eldest brother what I want to say. Tell him to be careful on his journey!"

When he returned to his bedroom, it was already late.

Eleven came back in a hurry, looked at her coming back from outside, and seemed to want to say something but stopped himself.

Xiao Ruyu saw the lotus seed soup in his hand and came forward with shining eyes.

[Eleven, I was wondering why I didn't see you all afternoon. Turns out you went to make lotus seed soup for me.]

Before Eleven could react, Xiao Ruyu's little hand touched the bowl of lotus seed soup.

[Eh——]

【Why is it cold? 】

Seeing her puzzled look, Eleven hid the bowl behind him awkwardly and spoke stutteringly.

"Eleven... go and warm up the little princess..."

After saying that, he turned around and went to the inner kitchen.

Xiao Ruyu looked at his back and vaguely felt that something was wrong with him recently, but she didn't think too much about it. She just thought that he was busy with other things and had forgotten about it.

She yelled at the back, "Add more sugar."

…

Xiao Ru'an had been out of the palace for more than three days to investigate, and the first letter had also been delivered back to the capital.

Nan Xu was standing outside the hall. When he saw Xiao Ruyu appear, he quickly waved to her.

"Little princess, this way!"

As soon as he saw him, Xiao Ruyu knew that it was Xiao Ru'an who brought him the letter, and he came over with a happy look on his face.

She couldn't wait to open the envelope and scan the contents of the letter at a glance.

"Let me see what letter my eldest brother has written to this princess."
