Datang Institute of Technology

"Xiao Langjun, what are you?" Xu Zheng asked suspiciously.

Zu Youming cupped his hands.

Xu Zheng thought, he really is a scholar.

Zu Youming said, "Student Zu Youming, my family ancestor is a Ph.D. in computing from the Imperial Academy..."

When the ancients introduced themselves, there were routines. When introducing themselves, they had to bring people their own sources.

It may be due to this habit caused by the heyday of the aristocratic genre.

"The student accidentally saw a calculation tool called the abacus used by the Xu family's children at the market..."

Xu Zheng was taken aback for a moment, he actually came here for abacus, he only knew that Changsheng drum made up this matter, and he didn't know anything else.

So he beckoned, "Changbai, come here, so I can answer this gentleman's question."

"Oh." Brother Changbai replied, he didn't really want to come to Chang'an, he might as well listen to Changsheng's lecture on Journey to the West at home.

The other children also didn't want to come to Chang'an, which they had rarely seen before. It was Xu Changsheng's repeated promise not to secretly tell Journey to the West that they came.

Zu Youming praised a few words first, "Little brother is really an arithmetic genius, he did the calculations quickly and accurately just now."

Brother Changbai's chest straightened up, he looked a bit like Xu Changsheng, and thought, that is, he is the eldest student of the little fairy, and he is the best at arithmetic.

Zu Youming asked directly after boasting, "I don't know if the little brother's arithmetic was taught by Mr. Xu Wenyuan? It's really a family tradition."

So many Xu family children have unique calculations, which should be learned at home.

Brother Changbai was taken aback, and replied, "It wasn't taught by my grandfather."

I can't learn what my grandfather taught me, and I'm not very good at it.

Zu Youming was stunned, isn't it the great Confucian Xu Wenyuan?There seems to be no famous people in the Xu family, right?

Pointing to the abacus in doubt, "Then where did you learn arithmetic?"

Brother Changbai straightened his chest, and when he mentioned this, he was proud, and said loudly, "Of course I learned it in the Huaguo Mountain Water Curtain Cave, and the little fairy taught us personally."

That is the place where the Monkey King lives. He likes the Monkey King the most. The most important thing is that he was the first to discover the Water Curtain Cave. He is the strongest supporter. Except for the Water Curtain Cave, other places are Mountain Kaka.

Recently, Changsheng was there to teach them numerology.

Before Zu Youming could react, a group of angry children surrounded him, "Our Fangcun Mountain's Xieyue Three-Star Cave is the orthodox abacus. "

Brother Changbai felt restless, "Who are you talking about Shankaka?"

There was also a group of shouts from behind, "Dare to question our Shuiliandong, beat him."

Two groups of children staged a full martial arts.

It didn't stop until Xu Zheng punished them all to stand.

When Zu Youming left, he was a little dazed, because no one answered his questions, and they all went to fight.

However, he also got a lot of information.

The abacus of these children was learned from two great academies respectively.

One is called Huaguoshan Water Curtain Cave.

One is called Fangcun Mountain Oblique Moon Samsung Cave.

However, after thinking about it for a long time, Zu Youming has never heard of these two colleges.

But it must be a great school to create a simple and practical arithmetic tool like the abacus, at least unique in mathematics.

It's just that these two colleges are fighting for the orthodox ownership of Abacus, and I don't know what's going on?

There is also a lecturer named Xiaoxianren who seems to be very powerful.

Zu Youming thought to himself, maybe he would have to tell his grandfather after he went back that he was going to visit these two great academies.

In ancient times, the speed of information dissemination was very slow. Even if you made some great knowledge, it was difficult to spread it in a short time.

In order to learn the strengths of each school, the term "study tour" has been formed. By visiting various colleges, you can learn different knowledge and increase your knowledge.

This is another explanation that it is better to travel thousands of miles than to read thousands of books, because a learned man must gather the strengths of a hundred schools of thought, rather than working behind closed doors.

After Zu Youming went back, he really found his grandfather, the old doctor of Guozijian.

Old Dr. Fang was taken aback, "It's really an amazing subject of mathematics, but the roads have been blocked by heavy snow recently, making travel inconvenient. If you really want to visit these two academies, you can wait until spring begins."

Zu Youming nodded, it is indeed a bit inconvenient now.

Zu Youming also told his grandfather about the little fairy, "I don't know what kind of great arithmetic master this little fairy is?"

Dr. Fang Lao smiled, "It's actually easy to know."

Zu Youming was slightly startled, what do you mean?

Dr. Fang Lao pointed to a piece of paper on the table, on which was Xu Changsheng's arithmetic problem that made the Imperial College restless, "You can write to him and bring this problem."

Zu Youming's eyes lit up, that's right, he can write a letter for the children of the Xu family to take it with him.

Dr. Fang Lao is also a math fan. After learning about this pioneering math tool, he couldn't help but tell his other colleagues, that is, other doctors from the Imperial College.

As a result, the reputation of the two colleges of Huaguoshan Water Curtain Cave and Fangcun Mountain Xieyue Sanxing Cave spread like wildfire in the Imperial College.

But what they don't know is that the two names of Huaguoshan Water Curtain Cave and Fangcun Mountain Xieyue Sanxing Cave are being circulated in Chang'an City in other ways.

Because after the people of the Xu family sold out their gasoline, both adults and children were enjoying their rare leisure time. In their spare time, they had to put on a dragon gate array, and the one on display was Xu Changsheng's latest Journey to the West.

The point is that they discussed it in the shop, and they didn't avoid suspicion or anything.

Then, from time to time, people gathered around to listen, and they couldn't walk when they heard it.

Xu Changsheng just talked a little bit, and he finished listening to it very quickly.

Why not share such a wonderful story with three or four friends?

So one pass ten, ten pass one hundred...

"Journey to the West" somehow became popular in Chang'an, and...it became popular, even if it was just the beginning, it was so popular that it exploded.

When "Journey to the West" spread like wildfire, Xu Changsheng's letter was also sent to Li Chengqian.

Above the Golden Palace, the attitude of the Turkic envoy A Shina became more and more tough.

A group of courtiers are ashamed and depressed to death. They are absolutely not afraid of anyone when they are scholars, but such a difficult problem...

Li Shimin also had a dark face. He tried his best to delay for so many days, but he couldn't solve any of the two problems of the Turkic people. He was manipulated time and time again by the other party.

Today, Ah Shina is obviously ready for a showdown.

The whole hall was full of sorrow.

A Shina stepped forward with a smile, "Your Majesty the Tang Dynasty..."

Before he opened his mouth, Li Shimin said, "It's already noon, Turkic envoy, let's discuss after lunch."

Li Shimin lowered his face and delayed one last time, although he no longer had much hope.

How long can lunch be?

No matter how delayed it is, it is impossible to have a lunch from noon to night.

But at the end of lunch, Li Chengqian also received a letter from Xu Changsheng.

Above the main hall, Ah Shina straightened his clothes and put on a formal appearance. It was time for him to ask for a loan. Tang people pay attention to the right time, place and people, and now is the right time. "Your Majesty the Tang Dynasty, I only represent the Turkic Khan Towards……"

Li Shimin couldn't help it, his face was so black that he couldn't solve other people's problems.

"Wait a minute."

Suddenly, a voice sounded.

Everyone was stunned and looked in the direction of the voice. Would the prince still delay?But the matter has come to this point, no matter how much delay it will be of no avail.

Li Chengqian came out, "Turkic envoy, don't you think that the tricks of the two Jianghu people are all about me, Tang Dynasty?"

The corners of Li Chengqian's mouth twitched a little, because Xu Changsheng's letter said so, and he was just about to put these two questions on the ground and step on them, as much disdain as he wanted.

When Li Chengqian spoke, he was inevitably misled by the tone of the letter.

Baiguan looked at Li Chengqian with weird eyes, and called the two problems a trick of the rivers and lakes with such disdain, but they were indeed stumped.

But they also agree with this statement, what kind of knowledge are these two questions?It's obviously a strange and obscene skill.

In ancient times, people didn't pay much attention to strange and obscene skills, only reading was high.

Ah Shina frowned, "I don't know what the Great Tang Prince thinks?"

Li Chengqian did not answer, but said to Li Shimin, "Father, my son was discussing academics with my friend recently, and I accidentally mentioned two problems with the Turkic envoys. I didn't think about it, but my friend ridiculed me and said Is this also called learning?”

He really didn't talk nonsense, he almost said directly in the letter, why are you so stupid, you don't know such a simple question.

When Li Chengqian read this letter, a short-legged figure with upturned nostrils, flaunting his might, and lawlessness appeared in his mind.

All the officials in the palace were stunned, mocking His Highness the Crown Prince?Prince this friend is really...

But listening to the tone, the prince seemed to be able to solve these two problems, so he couldn't help discussing in a low voice.

"Your Highness, the friend you mentioned is the Xu family's son who stumped the Imperial Academy with a calculation problem mentioned last time." Kong Yingda, who was offering wine to the Imperial Academy, asked.

"Exactly." Li Chengqian replied.

I don't know why, as soon as he gave this answer, the corners of Li Shimin's mouth kept twitching.

Li Chengqian took out a letter from his arms, "Father, the answer is on it."

When the prince took out the letter, he seemed to avoid everyone's eyes on purpose.

Is there something shady on the letter?

Li Shimin shuddered a little when he thought of the chicken claw writing, and he couldn't be blamed for it. None of the folds and the like that he came into contact with were written by officials who were successful in calligraphy.

He said directly, "Since the prince already knows the answer, there is no need to show it to me, just announce it."

A group of officials who are very familiar with His Majesty couldn't help being taken aback. Why does His Majesty seem to be avoiding it?

What kind of monster is that letter? I have to go and see it later.

Li Chengqian looked at the Turkic envoy, pointed to the oil pan on the hall, and said directly, "Turkic envoy, is this really an oil pan? Or is it just a thin layer of oil on top of the vinegar?"

Everyone was stunned, and their noses couldn't help moving. It really smelled like old vinegar. Affected by the oppressive atmosphere before, they didn't notice this, but so what?

Above the main hall, only the voice of Li Chengqian talking peeping was left.
