Hearing Zhu Zhanyan's question, Chen Kan slapped his head.

He was speechless, he remembered that he had only said once that the Pythagorean theorem was used to screen for nine leaky fish, but he didn't expect to be remembered by these little guys.

Since then, no matter who has tested them, they have always asked only this one question.

If the other party can answer, they will talk to others well, and if they can't answer, they will scold people.

Now that Chen Qia is also talking, Chen Kan is really speechless.

However, he had already reminded Chen Qia just now, and if Chen Qia didn't listen, it had nothing to do with him.

Sure enough, Chen Qia's hand holding his beard paused, and his face showed a look of confusion.

The Pythagorean theorem is recorded in the major arithmetic scriptures, and Chen Qia is well-read and naturally knows it.

But what is this inverse theorem?

Noticing Chen Qia's expression, the three little guys glanced at each other tacitly, then shook their heads and said in unison: "Nine leaky fish." ”

"Forget it, it's boring, let's go out and watch it later."

Zhu Zhanji muttered, turned his head to look at Chen Qia, and said, "Since Mr. Chen can't even answer the questions raised by a six-year-old child, I unilaterally think that Mr. Chen doesn't have the ability to compare the knowledge of the three of us, so let's stop here!" ”

As soon as these words came out, I saw that Chen Qia's face turned red visibly.

Seeing that Chen Qia's old face was a little unbearable, Chen Kan coughed lightly, turned his head to look at Zhu Zhanji and reprimanded: "Don't be rude to Mr. Chen!" ”

Zhu Zhanji stuck out his tongue and didn't care about Chen Kan's reprimand.

Reprimanded Zhu Zhanji, Chen Kan turned his head to look at Chen Qia and said: "Mr. Chen's forgiveness, these little guys are spoiled by Ben Hou on weekdays, by the way, when the meeting is about to start, why don't Ben Hou lead the students out for a walk?" ”

Chen Kan is telling the truth, these three little children are indeed spoiled by him, compared to other decent and one-eyed children in the Ming Dynasty, these three little children are very out-of-the-box.

However, Chen Kan also did it intentionally.

In his opinion, children should be like children.

At a young age, he looked serious like an old antique, it was not elite education, it was the product of educational failure.

Chen Qia had a step, and he no longer mentioned the matter of comparing the knowledge of the three little guys, but looked at Chen Kan and said, "In this way, there is Lao Houye." ”

Chen Qia could see that the three little guys were playing him like a fool.

However, this is his own way, or under Chen Kan's reminder, although he can't hold it on his face, he doesn't have any opinions about the three little children.

Chen Kan had already experienced the lantern festival in the north last year, and this time he was familiar with the road.

The Hou Mansion prepared warm clothes and snowmobiles, as well as some small snacks.

The three little ones were taken by Chang Ning to play with them, and Chen Kan took Chen Qia to walk alone towards the place where the ice lantern was.

The ice lanterns on the Jinshui River are also a must in Beijing, not to mention that Chen Qia is not the kind of person who loves to be lively.

The two walked among a group of huge ice sculptures, Zhang Dong led a few guards to isolate all the tourists who squeezed towards them, and the two held paper umbrellas, and walked leisurely and elegantly.

Chen Qia's eyes widened as he watched these ice sculptures, and couldn't help but be amazed: "It's really a miracle." ”

Chen Kan nodded and said with a smile: "You can't see such a beautiful scenery in the south of the Yangtze River, the north has had a tradition of storing ice since ancient times, and these are just part of it, more ice has entered the ice cellars of each family." ”

While the two were talking and laughing, they walked to a row of ice cubes, and although it was winter, there were many foods made of ice in the igloo.

Chen Kan cushioned the money bag, looked at a shop selling popsicles made of sugar water, and discharged six big sons: "Two small Xiaoice sticks." ”

The shopkeeper took the copper coin with a smile, took out two tiger-shaped popsicles from the ice cellar made of ice cubes and handed them to Chen Kan, and said with a smile: "Guest, there are all kinds of pastries and hot drinks in the villain's shop, but you have to go in and take a break." ”

Hearing this, Chen Kan turned his head to look at Chen Qia: "What does Mr. Chen think?" ”

Chen Qia nodded, entered the door and ordered: "Make a pot of tea, and serve any special snacks." ”

"Well, you two wait."

The two of them entered the door and found a desk to sit down, and Chen Qia couldn't help but be amazed: "I have heard that the people of Mobei have a tradition of Lei Bing as a house, and I never thought that I could see it in Beijing." ”

Chen Kan sat down opposite Chen Qia, and couldn't help but chuckle when he heard this: "There are many strange things in the world, and Ben Hou has also heard that there are religions in the West that cast stones for the court and houses, which can be immortal for thousands of years. ”

Chen Qia stopped his hand: "Where Ru Mao drinks blood, don't mention it, don't mention it!" ”

"Huh!"

Chen Kan chuckled, but didn't say much.

Scholars are all so urine, thinking that the Ming Dynasty is the center of the world, and other places are barbarian lands, and they want them to accept other civilizations, unless this civilization can be assimilated by the Han civilization, otherwise they will always be this arrogant appearance.

Chen Kan just followed their words and mentioned them casually.

Anyway, with the advent of the Age of Discovery, sooner or later exchanges between the East and the West will become more frequent, and even if they want to exclude them, the people who have benefited will not agree.

There is no fire in the igloo, but its warmth is no less than that of the warm Hou Mansion.

The two had a pot of tea and chatted a lot unconsciously.

When Chen Qia wanted to renew the second pot of tea, a little maid suddenly walked into the ice dance, came to the two of them and arched his hand: "Two adults, my master is invited." ”

Chen Qia glanced at Chen Kan and asked, "Who?" ”

Chen Kan glanced at the little guy up and down, and then said with a smile: "Creditor! ”

"Creditor?"

Chen Qia's face was suspicious, and then asked, "Go and see?" ”

"Let's go!"

After speaking, Chen Kan came to the counter to settle the bill, but was told that someone had already settled.

Chen Qia said with a smile: "Nothing to be courteous, either a traitor or a thief." ”

The two little guys stood beside the two respectfully, neither saying who their master was, nor did they have any expression for the comments of the two who were either treacherous or thieves.

"Lead the way!"

Chen Kan waved his hand, and the little guy immediately trotted forward and led the two to a carriage.

Chen Kan went straight into the carriage, and Chen Qia followed.

The little servant drove the carriage and squeaked towards the restaurant in the upper reaches of the Jinshui River.

Familiar people in familiar places, this time, Zhang Guan did not sit in the private room and wait for Chen Kan and Chen Qia, but stood at the door of the restaurant with a wry smile.

It seems that someone else cleared the scene, because Chen Kan did not find anyone other than the restaurant staff in the restaurant.

"There is Lord Lao Zhang for a long time, and this Hou is also wrong."

Chen Kan jumped out of the carriage and greeted Zhang Guan with a smile.

Chen Qia and Zhang Guan are also old acquaintances, so the moment they saw Chen Qia, Zhang Guan's face flashed a moment of distraction.

Didn't it mean that Chen Qia had already died in the fire of Jinyi Guard's Prison, why would he still be here?

But Zhang Guan is a smart person, and he quickly figured out the joints, and couldn't help laughing at Chen Qia: "I don't know that Uncle Yuan's brother is also there, and the foolish brother is rude." ”

Chen Qia arched his hand towards Zhang Guan and stopped talking.

Zhang Guan didn't care when he saw this, but just stretched out his hand and said, "Master Hou, uncle and brother, please!" ”

Chen Kan nodded and stepped into the door with his hands behind his back.

It's still last year's private room, but this time, there's one more person.

Chen Kan came to the private room and sat down, and said with an unintentional smile: "Ben Hou just returned home today, and he received an invitation from Lord Zhang without thinking about it, and Lord Zhang is quite well-informed." ”

Zhang Guan was stunned for a moment, and then pretended to be stupid and said: "It's just the right time, it's just the right time." ”

Chen Kan smiled slightly, and didn't say much.

Zhang Guan was monitoring the Hou Mansion, which was not unexpected by Chen Kan, and the meaning of saying this sentence was just to knock it with his hand.

It was Chen Qia, after hearing Chen Kan ask this sentence, Zhang Guan's eyes suddenly became inexplicable.

He also thought that Chen Kan had no taboos when he arrived in Beijing.

Now it seems that it is not what he imagined.

But after a while, he couldn't help but feel a little pity when he looked at Zhang Guan's eyes.

Watching Chen Kan, he was also arrested by him, and with Chen Kan's temperament, he was able to conclude that this person's fate would not be too good.

The three of them sat down with different thoughts, and since the whole restaurant was full of guests at their table, the dishes were served quickly.

It's just that a few people didn't move their chopsticks much.

Chen Kan and Chen Qia are not hungry because they are full at home, but Zhang Guan is hiding things in his heart, so he has no appetite.

So, the atmosphere suddenly became a little weird.

Finally, Zhang Guan couldn't help but speak: "Master Hou, now that the construction of Beijing City has been largely completed, the amount of cement has gradually decreased. ”

Before Zhang Guan's words were finished, Chen Kan waved his hand and interrupted: "It's okay, no matter how much cement is used in Beijing, since Ben Hou said that the full amount will be provided for free, he will not break his promise." ”

"That's not what this official meant."

"That's not what it means, what does that mean?"

Chen Kan looked at Zhang Guan with a smile, and Zhang Guan's scalp was a little numb.

Now facing Chen Kan, he really doesn't know how to speak.

Before today's banquet began, he had been doing psychological construction for a long time, but when he really saw Chen Kan, he was still a little ashamed in his heart.

Seeing that he was speechless, Chen Kan was not in a hurry.

Zhang Guan was looking for something about him, he already knew it when he came, it was nothing more than for the name of royal cement.

A year has passed, and Chen Kan estimates that he should not be able to withstand Zhu Di's pressure.

After all, the name of the royal family was sold by him at a low price for the cement of a Beijing city, and Zhu Di would be a ghost if he was not in a hurry with him.

You must know that perfume and soap bring millions of profits to Zhu Di every year, but they have not been able to bear the name of a royal family.

Catching up with Chen Kan's smiling gaze, Zhang Guan gritted his teeth, and finally clarified his intention today.

"What this official means is that in the future, the cement that Hou Ye provides to Beijing City can be purchased by this official at the market price."
