"As the Taishi said, I have made a little success in arithmetic, since the two of you came to my Datang to learn culture, it is inconvenient for me to cherish myself, so I will say something simple, let you listen to it first."

Jia Yi saw that the two Tang envoys really looked at him, and chuckled lightly in his heart, and first briefly explained the points in the high number.

This kind of knowledge, which is so profound that it is almost impossible to be of any use in the Tang Dynasty, not only made the two Tang envoys dumbfounded, but even Mr. Li Gang widened his eyes and didn't know what Jia Yi was talking about.

"What, don't you understand?"

"Sir, I can't wait until I can, please don't hesitate to give advice."

Pharmacist Huiri bowed to Jia Yi to the end, his attitude was extremely good, this kind of profound knowledge, he heard of it for the first time, since he came to Datang to study, then he naturally had to learn the best, Jia Yi said that he couldn't understand, and he observed, and found that the prince and master Mr. Li Gang couldn't understand either, that must be the most profound knowledge, and learning to hand is of course an inevitable thing.

Jia Yi smiled, and told the two people about the calculation method of the integral, when the formula of the integral was presented on the paper, the two people naturally knew what it was, but the reason for it was still not clear, just wanted Jia Yi to give a detailed explanation, but Jia Yi's mouth was changed to a different channel.

"You see, I have already shown you the arithmetic of the supreme god of the Tang Dynasty, should you also express it?"

The most important thing for people who do learning is to only talk about learning and not talk about anything else, if you add chips to the body of learning, then learning will change its taste, plainly let the high learning in the clouds be contaminated with dust and mud, in the cognition of the pharmacist Huiri, this is a blasphemy of learning, but these words really came out of Jia Yi's mouth, so that the corners of his mouth couldn't help twitching fiercely, but he could only say helplessly: "I don't know what the lord wants to know from me?" ”

"I know that there are thousands of miles of sea between your Wa Kingdom and my Datang, to be honest, I am very curious why your ship did not capsize in the waves, you must know that the sea breeze is not a little bit more violent than the river wind, can you share your shipbuilding skills with me, of course, I can also share with you my supreme arithmetic here."

Speaking of the art of shipbuilding, Yakushi Huiri's head suddenly raised, they are surrounded by the sea, it can be said that they live on the sea, since they live on the sea, then they will inevitably build a sea ship that is difficult to capsize in the sea, this is their strength, of course, they should be proud.

"When it comes to shipbuilding, our country is naturally a hundred ......times more than the Tang Dynasty."

Jia Yi really doesn't want to listen to this kind of nutritious bullshit, but people really have a way at hand, so they have no choice but to listen to it when they are farting and when they are serious.

Pharmacist Huiri said that the art of shipbuilding was endless, from the overall structure of the ship, to the local internal facilities of the ship, in short, in Jia Yi's mind, a sea ship slowly showed its proper appearance, asked Li Gang for a blank paper, and found a charcoal pencil, and the ideas in his mind were directly presented on the paper, this year there is no such super-developed engine, everything still needs manpower and wind power, so the ship is relatively simple, and soon Jia Yi drew a picture of the structure of a ship, Let the pharmacist Huiri take a look, and immediately let him treat Jia Yi as a celestial, because this method of drawing is definitely a profound technique.

Pharmacist Hui Ri was just about to ask Jia Yi for this drawing method, but Jia Yi wrote the formula of calculus on a piece of paper, telling him that this is a more advanced knowledge than the integral, seeing the two Tang envoys of calculus, he was immediately attracted by this inexplicable thing, and he studied for a long time without any clue, and saw that Jia Yi was chatting happily with Li Gang, so he was really embarrassed to disturb, so he could only say goodbye and prepare to go back and study it again.

After the pharmacist Huiri and Inugami Mita left, Jia Yigang was about to say goodbye and leave, but was stopped by Li Gang.

"Jia Yi, the integration and calculus you just mentioned, although the old man can't understand it, but he also knows that this is definitely the most advanced knowledge, why did you tell the two Japanese people so simply, you need to know that the heart of the non-my race must be different."

Li Gang frowned and looked at Jia Yi, expressing great dissatisfaction with Jia Yi's behavior.

Jia Yi smiled slightly and explained to Li Gang: "Old gentleman, these integrals and calculus are useless at all now, if they are placed in thousands of years later, they may still be able to make achievements, now, take them back and study them as knowledge, it is okay, if you want them to work, it is impossible at all, but the mathematics that the kid gave to Xin Guangmao and Ma Zhou at the beginning is more practical." ”

Although Li Gang didn't know why Jia Yi opened his mouth to say thousands of years later, he also felt that what Jia Yi said made some sense, at least with his experience, he didn't understand what the use of these two kinds of knowledge was.

"It's good that you know, you need to know that the cultural inheritance of my Han nationality for thousands of years is to pave the way for my descendants, and we must not let these foreigners go, otherwise it will be harmful to my Datang and not beneficial."

Although culture knows no borders, there may still be 90 percent of the people in the Tang Dynasty who do not know how to write words, and the people of their own country have not yet fully exposed to the huge benefits brought by culture, so how can they let foreigners taste the sweetness first, Li Gang's insight has no problem with this.

"The kid was taught."

"Well, the old man thinks that you can start a sect on the way to arithmetic, but I heard that you have only accepted two disciples so far, if you can, don't learn from those old pedants and cherish themselves, and regard your own knowledge as more important than your life, wouldn't it be better to teach more people and let them benefit the Tang Dynasty and benefit the people?"

"Well, old gentleman, the boy, take it to heart."

Hearing this, Jia Yi's respect for Li Gang is already from the heart, in Datang, a family that will be stuffed under his bed as long as there is an uncommon book, Li Gang can say such a thing, which is enough to get Jia Yi's respect, and there are people with this kind of opinion, and it is estimated that there are only two of them left in Datang.

In ancient times, it was said that their own knowledge was inconvenient to pass on, but if you look at Confucius, and then look at Mencius and Laozi, which of them did not receive countless disciples, and spread their knowledge throughout the world for talented people to learn. It also made these cultures, which should have left a strong mark in the long river of history, come to naught, disappear without a trace, and waste the summary of the ancestors.

If everyone in the ancients had this opinion of Li Gang, why worry that the Tang Dynasty is not rich, and why worry that the Tang Dynasty is not strong.

"The old man heard that you don't have a table word yet, although the old man is not your teacher, but he wants to give you a table word on his behalf, what do you think?"

The table word refers to a person's words, let's say Qin Qiong, the surname is Qin, the name Qiong, the word Shubao, which is why some people call Qin Qiong Qin Shubao.

Being able to get Li Gang's words, which is also an honor in itself, how could Jia Yi have a reason to refuse, and immediately bowed to the shrine and thanked Li Gang for giving words.

"You are still young, although you are an adult, but your heart is not stable, the old man will give you words to cultivate the truth, take a solid heart, seek truth and pragmatic meaning, what do you think?"

Jia Yi heard what Li Gang said, and knew that this word was not ordinarily good, and immediately bowed again, and then left Li Gang's mansion with the drawings happily.

The carriage was halfway through, and Jia Yi found out that this word is really not half rotten, fake one pays ten, isn't this an advertising slogan, Li Gang is the rhythm of making us a businessman.

It's impossible to change it now, and I believe that this word will spread throughout Chang'an in a short time, I hope no one will find out the secret, and Jia Yi can only pray in his heart.

The drawings are in hand, then the next thing is modeling, it is not enough to have graphics, there must be a corresponding model, Datang's battleship is destined to be the kind of huge existence, so Jia Yi will also make some changes to the sea ship to make it more in line with the needs of combat at sea.

When I got home, I saw that it was still a group of friends, Jia almost turned his head and ran, the matter of the Hundred Flowers Race has been arranged, everyone has a place to be responsible, are they really so idle?

"I said that if you don't come to my house, you won't be able to live, right?" Jia Yi tightened the drawings in his hand, and said speechlessly to the group of friends standing in front of him.

"What's in your hand?" The eldest grandson rushed over with an arrow step, and reached out to snatch the drawings in Jia Yi's hand, but was flashed by Jia Yi.

These turtles know a fart, how can they master such a profound skill as looking at the picture, there is only one ending if they fall into their hands, that is, it will be damaged, the ship model has not been built, and now it can't be destroyed anyway.

"Give you five counts of time, give me the fuck off, otherwise if you build a ship in the future, 100% nothing will happen to you, start now, five ......"

Seeing Jia Yi's black face, all the friends suddenly dispersed like birds and beasts, in order to prevent these bastards from disturbing again, Jia Yi decided to return to Jia's Manor immediately, when will the Hundred Flowers Fight bloom, and when will he come back.
