After returning from the British Embassy, the next day, Xie Dongfa also came to visit Chen Muwu's residence.

He made a special trip to deliver news for the Chinese People's Legation in France.

Chen Muwu has made such great achievements in the Paris Olympics, and Chen Zheng, as the minister to France, thinks that he must also meet with this hero and take two photos.

This is his great achievement in office, and when he returns to China in the future, he can also become a capital when competing in the officialdom and political arena.

So he found Xie Dongfa and asked him to invite Chen Muwu to meet at the legation on his behalf.

When he received this invitation, Chen Muwu's first reaction was that he didn't want to go.

When he was still in the UK, he sent a telegram to the legation in France and did not reply, and even asked Zhu Zhaoxin of the legation in Britain to inquire about how to register for the Olympics through diplomatic contact, but your old gentleman still pretended to be dead.

Now that I have won the gold medal, I want to come and pick peaches, what have you done earlier?

But it was Xie Dongfa who came to the door, during the Olympic Games, this person helped him run before and after, and never cared about the return.

Chen Muwu could pat his ass and leave, but this guy will still have to mix in France in the future, and if he doesn't go this time, it will not be appropriate for him to be implicated.

So Chen Muwu still agreed to this invitation, and asked people to pick up Ye Gongchao from the villa in the suburbs in advance, and prepared to take him to meet the minister in France.

Establish a relationship with the minister in France, if Ye Gongchao encounters something in Paris in the future, he can also make it convenient for the legation.

When I saw Ye Gongchao again, he had long lost the graceful demeanor of a gentleman, his beard was unshaven and his eyes were blank.

The last time he took the drunk away from Chinatown, Chen Muwu told him and de Broglie to learn French.

However, De Broglie's identity, although he can't deign to teach him personally, it will definitely not be a problem to find a few teachers.

And in aristocratic families, it should be a normal thing to find a few old-fashioned governess teachers who are knowledgeable but have a strict teaching style, right?

Therefore, in the past few days when Chen Muwu was in the Olympic Games, Ye Gongchao ate and drank well in the suburban villa, and he was dedicated to learning.

"Gongchao, I haven't seen you for a few days, how are you doing in your French studies, and have you made any progress?"

When Ye Gongchao saw Chen Muwu, it was like seeing a savior, he finally called the right generation this time: "Han...... Third Uncle Chen, Third Uncle Chen, I really know that I was wrong this time! I'm not going to hang out with those fox friends anymore! ”

"If you know your mistakes, you can change them, and you can do good! Go shave, get a haircut, change into clean clothes, and accompany me to the legation tomorrow to meet the minister. ”

After meeting the minister the next day, Chen Muwu heard another compliment without any new meaning.

Chen Muwu had heard these words countless times at the party that De Broglie held for him after the game, and his ears were so hung that he couldn't grind out his ears.

However, Minister Chen has also found a fairly novel entry point.

He and Chen Muwu climbed up relatives, and said unashamedly that his surname was Chen, and his surname was Chen, and the two of them were one family five hundred years ago.

Who's with you is a family!

Chen Muwu, this Chen is from Jiang, and Chen Zheng, this Chen is from Wei Jian.

Thanks to his rich imagination, he was able to come up with such a ridiculous approach.

After a few words with the minister, Chen Muwu and Ye Gongchao were left in the legation by Chen Zhengqiang and had dinner together.

"Hanchen, you have been in Europe for more than a year, and during this time, you must not have eaten many hometown dishes. In my legation, it just so happened that there were a few cooks brought from China, and Ling and Gongchao stayed here tonight, and we had a family dinner, which by the way was also a celebration for your four gold medals in one fell swoop. ”

Chen Muwuxin said that the buddy ate a meal of Chinese cuisine almost every once in a while, and the person standing next to him should have a higher cooking level than his academic level.

When it was time for dinner, Chen Muwu knew why Chen Zheng said that he wanted to keep him for a family banquet.

The so-called family banquet, then there will be other family members of the host.

So during the banquet, Chen Zheng naturally introduced his wife and daughter, to Chen Muwu.

Chen Muwu felt that he had been committing a peach blossom in the recent period, first Cai Yuanpei wanted to accept him as a son-in-law, and now Chen Zheng wanted to introduce his daughter to him.

In Chen Muwu's heart, he is only twenty-two years old this year, just past the legal age of marriage stipulated in the "Marriage Law", and he can still be regarded as a young man.

But in the eyes of the people, he is not married at the age of twenty-two, and he is already a bit late in marriage and late childbearing.

What can I say about the appearance of Chen Zheng's daughter, it can't be said that it is good-looking, nor can it be said that it is called a middle-aged person, but it can only be said that it is quite ...... Rich.

Of course, even if this eldest lady of the Chen family fell into the fish and fell into the wild and the fairy descended to earth, Chen Muwu didn't want to have anything to do with the minister in front of him.

One of the most famous things in Chen Zheng's life was not because he signed the unequal "Sino-Russian-Mongolian Entente" in Kyakhta on behalf of the Chinese government.

It was because he himself was the highest-ranking official who was shot by the military commander during the entire War of Resistance Against Japan.

And the reason why Chen Zheng was shot by the military commander was because he became a traitor and became the foreign minister of Wang's puppet government.

To be a traitor's son-in-law?

How much can't he Chen Muwu think about it?

……

A few days later, the heat of winning the Olympics finally faded.

Chen Muwu wanted to take advantage of the time before the closing ceremony to write the remaining two papers on wave equations.

But although he wanted to write, some people didn't want him to write.

De Broglie has been in a good mood these days.

Because after matrix mechanics bothered him for more than half a month, de Broglie finally relied on the wave equation given by Chen Muwu to find another way to solve the problem.

So now every day he always "tortures" Chen Muwu in different ways, either to take him around Paris, or to take him to a winery in the countryside to see the precious red wine in a cellar where he is stored.

Chen Muwu really bothered, it seems that if he wants to settle down to write his thesis, he must first help De Broglie distract his excess energy.

Soon he came up with a solution, took out a blank piece of paper, and drew a nine-by-nine nine-by-nine squares on it.

And the third column, the sixth column, and the third and sixth rows of the dividing line were bolded, and the 81 squares were divided into three rows and three columns, a total of nine nine-square grids.

Then Chen Muwu casually filled in a few numbers, and then called De Broglie, asking him to fill in the nine numbers from one to nine in these eighty-one squares, and it was necessary to make each row, each column and each nine-square grid, the numbers only appear once.

Sudoku is a thing that has been rotten in the streets for a long time in later generations, but it is still a new thing.

It's a good idea to let Debroyi use it to pass the time and stop bothering himself.

Sure enough, using Sudoku, Chen Muwu successfully hid from Qingxian.

De Broglie was obsessed with these eighty-one squares, and Chen Muwu could also step down and write his dissertation quietly.

As for Ye Gongchao, who finally returned to human society, he was once again locked up in an empty room in this residence, and a new round of revisions was made to the first draft of "No One Left Alive" according to Chen Muwu's opinions.

Two days later, De Broglie, who had dark circles under his eyes, found Chen Muwu again.

"Chen, I have made a lot of the problems you gave me, but there are a few of them, and there doesn't seem to be the only solution."

There is no single solution.

It is said that at least seventeen numbers are needed for a unique solution to Sudoku.

But when Chen Muwu came up with the problem, he didn't have time to help De Broglie verify whether it was the only solution one by one, but just filled in a few numbers casually.

"Chen, this very novel puzzle is very interesting, does it have any name?"

"It's called su...... No, no, this thing is called Magic Square, Chinese Magic Square. ”

Since he gave Bohr a career plan, the Duke of York and the Crown Prince of Sweden to Zhuang Zhou Mengdie, Liang Shanbo and Zhu Yingtai, Chen Muwu feels that he has gradually become obsessed with cultural export.

Since I've designed the game mode of Sudoku in advance, it's absolutely impossible.,Put a sudoku name on it that you know at a glance.。

So he continued to flicker: "Louie, this kind of game of filling one to nine into the square has appeared in China thousands of years ago, our ancestors first called it 'Hetu' and 'Luoshu', and then called this kind of thing 'magic square'.

Later, with the trade between the East and the West, the Arab merchants also introduced the magic square to Europe while transporting Chinese goods to Europe.

"In the eighteenth century, the great mathematician Euler created a mathematical model called the Latin square on the basis of the magic square.

"Then, one day last year, I stumbled upon this research conducted by Euler in the library of the University of Cambridge, and I thought it was the same as the ancient Chinese game called the magic square, so I improved on both of them, and it became what you have now on the piece of paper.

"What do you think, is it still fun?"

"Absolutely, I've found that from mahjong to magic square, you Chinese seem to be very good at number games."

How did de Broglie come together?

Aside from the fact that they both use the numbers one to nine, there should be no other similarities, right?

However, he has been talking about the word magic square, and Chen Muwu suddenly thought of another similar phrase, that is, magic cube, Rubik's cube.

Fortunately, he couldn't live in France for a few days, otherwise when De Broglie got tired of playing with this magic cube, he would have to get the Rubik's cube out of the high, which once again made Monsieur Duke fall into deep self-doubt.
