But in this life, all this is destined to be a mystery, because it is impossible for Li Ke to let Songtsen Gampo marry the princess of the Tang Dynasty!

Of course, if you are willing to take the whole of Tibet as a dowry, and by the way, you are in free love with the princess of the Tang Dynasty, and my princess of the Tang Dynasty also takes a fancy to you, then you can, Li Ke has no objection. After all, Songtsen Gampo is only two years older than Li Ke, not those who have already reached middle age.

Let's not talk about whether Songtsan Gampo still has the opportunity to use troops to threaten the Tang Dynasty and marry the princess, even if he takes 10,000 steps back, in history, Lu Dongzan entered the Tang Dynasty to ask to marry the princess, but the matter of the six trial marriage history, as the princess's brother, my Li Ke's debut question is not too much, right? Li Ke has thought about the topic.

The Legendre orthogonal polynomial method is used to find the cubic best square approximation of the function f(X)=X Sin (π/2)X on [-1,1], and the error squared δ²(π=3.14) is kept to four decimal places.

If you want to answer, I, Li Ke, admit it.

"Yang Anning." Li Ke smiled and said, "Go and bring the prepared things." ”

"Yes!" Yang Anning immediately turned around and left.

Li Yan glanced at Yang Anning without moving.

Soon, Yang Anning and Li Changge walked out holding two square boxes of one and a half feet square.

Putting the box on the table, Li Ke said with a smile: "When we meet for the first time, I don't have anything to give to my brother, so I have prepared two gifts for you." ”

"Thank you, brother." Li Yan and Li Xin were both well-behaved, and they both gave Li Ke a salute and said.

"You're welcome, it's all little things that aren't worth much." Li Ke said with a smile.

"Brother, Xin'er and I met my brother for the first time, and we also prepared a gift for my brother." Li Yan said with a smile.

"Oh? What is it? Li Ke was a little surprised, and prepared a gift for him? This is rare, the gifts he received from childhood to adulthood were given by Changle and their sisters, and outsiders never received them, although Li Yan and they are also Li Ke's sisters.

Li Xin next to him blinked his eyes and didn't speak.

"It's a prescription." Li Yan said with a smile.

"Prescription?" Li Ke was stunned, he thought of all kinds of gifts, but he never thought that it would be a prescription.

"Yes, I heard that Tuyuhun is on higher ground here, and the sun is very sunny, and I have seen a classic, saying that if our soldiers from the Central Plains are stationed in Tuyuhun, Tubo and other places with higher altitudes are easy to get altitude sickness, and our Datang also calls it miasma, so I searched for a lot of people with relevant life experience, and then found a prescription."

"Or it can't be said to be a prescription, it is some herders who have lived in the alpine plateau for a long time, and they have similar symptoms and eat some herbs, which have a certain relieving effect. Although it may not be very effective, even if it can cure a person, it is still a hero who rescued my Datang as you said, brother. Li Yan nodded seriously, her delicate little face full of seriousness.

"And this little doll was embroidered by Xin'er herself, because Xin'er didn't know what to give, and asked the third brother not to laugh." Li Yan asked for a small doll from the maid behind her.

Li Ke looked at these two gifts, he was really surprised, and carefully looked at Li Yan again, not to mention that people are beautiful, the point is that they are as careful as a hair, this gift is really attentive.

Although Li Ke may not use it, after all, altitude sickness is a thing that has relevant introductions and medication methods in the barefoot doctor's manual that Li Ke obtained, although altitude sickness is actually a different way of helping, many people are because of different physical problems after climbing the plateau, inducing these diseases, collectively known as altitude sickness, and the cause is not the only one.

But the point is this heart.

Who would have thought of that?

"I have to thank you for tens of thousands of soldiers in Datang." Li Ke said with a serious expression.

"Brother is polite, just like you said, brother, I'm also a long-term border general, and I'm the same as the family of those ordinary soldiers, so I want to do something for them." Li Yan breathed a sigh of relief and said seriously.

His Royal Highness likes it, and it is not in vain that she has been thinking about it for several days.

"Xin'er's is also very attentive, my brother has never seen such a delicate one, thank you." Li Ke said to Li Xin with a smile again.

"What my brother did, Xin'er and I admired it tightly, you are a big hero in both of our hearts! We are new here, and there are no acquaintances here, can Xin'er and I often come to play with you, brother, I have heard a lot of news about Chang'an City, brother, you have a lot of delicious food here. Li Yan asked with a grin.

"Hahaha, no problem, you two can come whenever you want." Speaking of this, Li Ke instantly became proud, just kidding, I have traveled through so many years, that is, I have a little say in terms of food, and everything else is not worth mentioning.

He felt that after the development of his world for more than a thousand years, the number one gourmand evaluated by netizens throughout the ages would definitely not be Su Foodie, but him Li Ke.

Looking at Li Ke's smug appearance, Li Yan wanted to laugh a little, His Royal Highness's personality is really similar to what I judged.

"Oh yes, I've already called someone to call Li Su, and you can meet General Li too." Li Ke remembered something and said.

"It's time for us to go see His Royal Highness King Liang." Li Daozong hurriedly said.

"How can he have that qualification, everyone should sit and wait." Li Ke waved his hand unceremoniously, and since Li Ke came, he was thrown away by Li Ke. Let him do anything, but Li Ke gave him a sentence, you can bully the herdsmen and the like at will, but anyway, if you say that you are the king of Liang, no one will believe you, and no one will listen to you from these soldiers, you can do it.

If he dare, Li Ke would go to find seven or eight herdsman girls who take a bath once a month to accompany him, don't you want to play? I'll let you play.

Taking a bath once a month Li Ke said a lot, and some are estimated to wash two or three times a year, and they are all washed on major shamanic festivals.

It's not that there is no water, but ...... Keep warm, at least there is no shortage of water in places like Qinghai Lake.

That's right, it's to keep warm! Many people think that even if they don't take a bath for decades, they are not like wild boars, how can they keep warm, but anyway, the herdsmen think so, and it seems to make some sense.

Anyway, ordinary herders get sick more often than people who don't.

Li Ke doesn't understand the principle, it is estimated that he understands medicine, or Sun Simiao should understand some, anyway, this thing has a certain scientific basis, the human body does not pay attention to an internal and external balance, you don't see how powerful the nation bathed in the Ganges River is after more than a thousand years, and it is okay for people to toss it. You go to another countryman, you learn to play once, and you don't come to me for seven or eight days.

I don't know if I felt it when I came all the way to the Western Regions, anyway, after coming to the Western Regions, Li Su was quite well-behaved.

After wandering around for a few days, Li Su went to the construction site and found a job as a supervisor by himself, and he did it himself twice when he had nothing to do, I don't know what he was thinking, but the change was quite big.

But Li Ke didn't bother to pay attention to him, it's not free-range, but there is some environment, you can change a person by throwing him into it, let yourself understand, everyone is happy when you understand it, and it's too late to fight if you don't understand it.
