"Brother, am I right?" Seeing that Li Ke was a little silent, Li Yan asked softly.

"Yes, if nothing else, it probably is. But why do you want to take the initiative to get married? Li Ke sighed, not to mention Li Shimin, almost all of the more than 20 princesses in the entire Tang Dynasty who were close to each other were clan daughters.

In fact, not to mention the Tang Dynasty, throughout history, most of the princesses of various dynasties and generations are almost all clan daughters, adopted daughters and the like.

"Because I'm worried about my sister." Li Yan hesitated for a moment, then sighed.

"Why is that?" Li Ke looked at her and asked.

"She has a very good relationship with me, what I just said to my brother, I inadvertently told her three years ago, she was still young at that time, who knew that she remembered, and then she was the same as me, took the initiative to learn the languages of these countries such as Tibet, understand their culture, and Xin'er is actually smarter than me! She learns faster! ”

"The point is that she often says that she wants to protect me, and I'm afraid that one day......," Li Yan paused here when she said this, and then continued, as if she had made up her mind: "Actually, there is another important reason that I am not the biological daughter of my parents. ”

Li Ke: "? ”

He looked at Li Yan with a confused expression, wasn't Li Daozong his own?

"I'm actually the daughter of one of my father's guards, my biological father died in battle with my father in the early years, when my father returned triumphantly, my mother was seriously ill, my father wanted to take care of our mother and daughter, but who knew that I was the only one left, I was three years old at that time."

"My father may think that I can't remember what happened when I was a child, and I never mentioned it, but although I don't remember much, I know that I was adopted by my father."

"And there were a lot of people who knew about this matter at that time, and relatives and other things represent the face of the Tang Dynasty, and the royal family daughter is a princess, even if these countries in Tubo know, they won't say anything, but if it is the daughter of an ordinary people's personal guard, I'm afraid it's not appropriate for this matter to spread out, so if there is really that day, Your Majesty is afraid that Xin'er will make Xin'er and relatives."

"Therefore, the little sister implores the elder brother, if there is a day, I can intercede for the little sister, the little sister boasts that her appearance is not bad, and I have been working hard to learn how to be a qualified princess, I am willing to be a sister and a kiss, please brother to be perfect." Li Yan stood up directly from her position, and then knelt directly on the ground.

"You get up." Li Ke hurriedly sat up and helped Li Yan to say.

"My sister didn't dare to kidnap my brother, I just asked my brother to help." Li Yan stood up along Li Ke's hand and said seriously.

Looking at the serious expression on the little face that had not yet fully opened, Li Ke suddenly thought of a sentence: The history book is very thick, it can fit China for 5,000 years, and the history book is very thin, it can't fit a person's magnificent life.

Li Ke is still not sure whether Li Yan is Princess Wencheng, or Li Xin, maybe she and Li Xin are not, but there is no doubt that the abbreviated words in the history books will never be able to record what they have experienced behind them.

In those seemingly glorious lives, what kind of pain and twists and turns they themselves experienced, and these can never be known from history.

"Who said you were going to kiss?" Li Ke suddenly said with a smile.

"Huh?" Li Yan looked at Li Ke a little blankly, is there anything wrong with this? Datang has already made peace, and His Majesty has not only promised these small countries to be friendly once, although it was not possible in the end for various reasons, but it can be seen that His Majesty does not reject this kind of behavior.

After all, they can stabilize a country with a single woman and buy years or even decades of peaceful development time for Datang, isn't it cost-effective?

Even Li Yan herself didn't think there was anything wrong, although it may not be fair to her, but how can there be so much fairness in life? It is already a blessing that she can grow up safely under the nurture of her father in this life.

So she didn't feel that she had any unfairness and grievances.

"Don't worry, Datang won't be able to get along in the future." Li Ke patted her thin shoulder and spoke.

"This ......" Li Yan was a little confused, but she didn't know where Li Ke's confidence came from.

"So you believe me. If there really is a day when you say, then I will definitely speak for you and let you go to kiss, okay? Li Ke said with a smile, he was afraid that Li Yan would not believe it, so he added.

"Thank you, brother." Li Yan saluted again directly.

"You're polite, you don't have to be so angry, in this way, you and Xin'er will be like Changle and them in the future, just call me the third brother." Li Ke said with a smile.

"Yes, third brother." Li Yan immediately changed her title directly.

"Then the third brother, the little sister won't bother you." Li Yan said softly again.

"What? After the matter of begging the third brother is done, you will run away. Li Ke made a joke.

"No, I'm afraid of disturbing the third brother's errands." Li Yan was a little embarrassed.

"You shouldn't have much to do since you came here?" Li Ke thought for a moment and asked.

"Hmm." Li Yan nodded, but she didn't explain, she believed that the third brother must have understood, like what women like them can do every day.

"If it's okay, you can come to me to help, it just so happens that I still need help with some things." Li Ke said with a smile, Li Yan's knowledge is good, to be honest, Li Ke really hasn't seen her so smart, at least Yang Anning and they are definitely not good, they are not at the same level.

Li Yan can think of these things at this age, she is already very powerful, and she has the thinking of people of this era, and coming to help can also give Li Ke some inspiration.

"If the third brother uses it, the little sister will come over every day." Li Yan hurriedly saluted, in fact, she was also very bored at home, Li Ke wanted her to help, of course she was willing, and she studied these things, isn't it also to do some practical things? Now there is a chance to test her abilities, and she certainly doesn't want to miss it.

Except for Li Ke, no one else was willing to give her this opportunity.

The main reason is that some of His Royal Highness King Qin's ideas and practices are really amazing, she learned a lot from Li Ke's body, for example, that day her father led the army to pick them up, and after Li Yan asked her father, she probably guessed what Li Ke wanted to do.

It's just that what she never expected was that Li Ke did more than she imagined! And it's bigger, too! The point is, the effect achieved is much stronger than she thought!

"So, I'll teach you math first, oh, math." Li Ke thought about it and said, mathematics is something that people pay more attention to in this era, but it is far less important than that of later generations.

In fact, it was said in later generations that mathematics is the foundation of everything, which is really very reasonable.

Therefore, based on this theory, the question he was going to give to the Tubo people was not to embarrass them.
