"What, you know how to do tai chi?"

Hearing that Qin Tian was going to teach Taijiquan, Mu Ti, Ah Lu and the others were shocked.

And at the same time they were shocked, they were a little worried.

Taijiquan can defeat Ah Lu, so if there are a lot of people in Datang who know Taijiquan, they Persia want to defeat Datang and have the land and wealth of Datang, but I'm afraid it won't be easy, right?

All of a sudden, they felt some fear, a very big, very big fear.

"This Qin Tian is really hateful."

Everyone thought in their hearts, but in the face of this situation, there was no way, Ah Lu was a little depressed, he always thought that he was quite powerful, but he was defeated.

And in the future, there will be more people who Datang can defeat him, right?

However, just when everyone was a little depressed, Numuti suddenly stood up again: "No, we Persia must not admit defeat, even in terms of force, we Persia are not the opponents of the Tang Dynasty, but we must fight for the face of Persia." ”

Persia can be said to be a hegemon-level existence in their region, just like the relationship between the Tang Dynasty and Tuyuhun, and the other countries in their place are all vassals of the Persian Empire.

As a big empire, even if they can't easily use troops against Datang, but they are defeated by Datang, they still want to fight for face.

Persia also had their own Persian face.

After saying this, he looked at everyone and asked: "Which of you has a good idea to make Datang lose face, even if he doesn't lose face, he must make sure that I Persia gets face back." ”

Everyone looked at each other, and at this time, a tall and thin man stood up.

The man was average-looking, but his hair was curly.

"My lord, I have a problem here, and I may be able to stump the people of Datang."

"Oh, what's that?"

The man smiled and took out a plank, which was divided into nine squares, each of which had a small square, and in these small grids were written some numbers, but not much.

"My lord, I named this thing the nine-square grid, in this nine-square grid, I have filled in some known numbers, and what people who play this game need to do is to add other numbers, and make sure that each number from one to nine only appears once in each row, each column and each house......"

This person explained the rules of the game, but after he explained it like this, both Ah Lu and Ma Ti didn't understand how the game was played.

They don't understand it at all.

And looking at these people confused, the man smiled: "This thing is very difficult, I came up with it, others have never played, many people even if they understand the rules of the game, it may take a day, and if you want to fill in all the unknown numbers, it will not work at all in a few days, it is me, if you want to fill a nine-square grid, it will take a day, and others need more, even, it will never be completed." ”

The more this person spoke, the more proud he became, and after listening to it, he was immediately overjoyed, and said: "Okay, this thing is good, then you can go to Datang's arithmetic museum, where people are all studying arithmetic, if they can't play this game, then Datang's face, it's hard to say, but remember, only give them three days, and not more, you this thing, after understanding the rules, try one by one, it may not take much time." ”

After Numti gave the order, the man nodded in response.

--------------------

In the late spring afternoon, the sun is quiet.

The Arithmetic Museum is a place established by Datang specifically to study mathematics, and the people here are indeed people who are very accomplished in mathematics in Datang, and the leader is Li Chunfeng, Taishi Ling.

They were responsible for compiling some mathematics books, and also annotated some previous works, such as the Nine Chapters of Arithmetic, and so on.

Li Chunfeng is usually very slow, and he doesn't stay in the arithmetic hall every day.

But he happened to be there today.

And just as he was discussing a problem with a group of colleagues, a subordinate hurriedly ran over: "Master Li, a Persian named Maas outside asks to see you." ”

"Persians?" Li Chunfeng frowned, looking a little nervous.

The Persians were looking for trouble with their Tang Dynasty, and they all knew about setting up a ring in Dongshi, but they were later defeated by Qin Tian, and now they suddenly came to their arithmetic hall, to say that they were not here to find trouble, Li Chunfeng They couldn't believe it.

The so-called, nothing to do is not to go to the Three Treasures Palace, they have never had anything to do with the Persian country.

It's just that they're very strange, they're just a place for research, what are the Persians doing here?

"Master Li, what should I do, see or not see?"

A colleague asked Li Chunfeng, and Li Chunfeng smiled: "They are obviously not good, if we don't even dare to see it, won't we be laughed at if we spread it?" ”

"That's right, in that case, let's send someone to call that Maas."

The men were ordered to retreat, and in a short time they called Maas.

And this Maas is the tall, thin, wavy man.

When Maas came in, he smiled, "How busy are you?" ”

Li Chunfeng was not in the mood to greet him, and said, "You are a Persian, what are you doing in my arithmetic hall?" ”

Maas said: "Under the name of Mas, is a mathematician in Persia, I like to study some things related to mathematics on weekdays, during this time, I have developed a game related to numbers, but, although the research has been made, but in the next is not talented, can not be cracked, I heard that your Datang Arithmetic Museum is full of talents, a lot of people, so I came to ask for advice." ”

Maas said politely, as if he was really here to ask for answers, but Li Chunfeng, who was not an extremely smart person, heard Maas's words, and then thought of the previous incident of Alu setting up a ring in Dongshi, and immediately knew that this was another provocation by the Persian state to them.

Deliberately brought something to make it difficult for them.

If they can't solve this problem, then Datang's face can't be put aside.

A huge Datang can't even solve such a problem, isn't that a shame?

Moreover, everyone has come to the door, and if you don't want to fight, you can't do it.

Looking at Maas's appearance, Li Chunfeng and the others couldn't help but want to beat him.

However, Li Chunfeng and they still couldn't help it.

Li Chunfeng's cheeks twitched slightly, and he said coldly: "Oh, it turns out that your Persian country also counts, it's really a strange news, but since you can't solve it, then let's take a look, maybe, we can teach you well, what is counting." ”

Since Ma Si said that he was here to ask for advice, Li Chunfeng went back.

When these words came out, Maas's cheeks suddenly became a little ugly, but he couldn't lose his temper.
