Upon hearing Zhu Zhanhe's question, Chen Kan slapped himself on the forehead.
He was speechless. He remembered that he only said once that the Pythagorean theorem was used to screen out the nine leaking fish. Unexpectedly, these little guys remembered it.
From then on, no matter who came to test their knowledge, they would always ask this question.
If the other party can answer the question, they will talk to them well, and if they cannot answer, they will scold them.
Now that Chen Qia was also interested, Chen Kan was really speechless.
However, he had reminded Chen Qia just now. If Chen Qia didn't listen, it would have nothing to do with him.
Sure enough, Chen Qia's hand holding his beard stopped, with a look of confusion on his face.
The Pythagorean theorem is recorded in all major arithmetic scriptures. Chen Qia has read a lot of books, so he naturally knows it.
But what is this inverse theorem?
Noticing Chen Qia's expression, the three little guys looked at each other in tacit understanding, 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 grunted, turned to look at Chen Qia and said: "Since Mr. Chen can't even answer the questions asked by a six-year-old child, I unilaterally believe that Mr. Chen does not have the knowledge to test the three of us brothers. With my ability, let’s stop this matter!”
As soon as these words came out, Chen Qia's face turned red visibly.
Seeing that Chen Qia's old face was a little helpless, Chen Kan coughed twice, turned to look at Zhu Zhanji and scolded: "Don't be rude to Mr. Chen!"
Zhu Zhanji stuck out his tongue and didn't care about Chen Kan's reprimand.
After scolding Zhu Zhanji, Chen Kan turned to look at Chen Qia and said, "Mr. Chen, I'm sorry, these little guys are spoiled by me. By the way, it's about to start later, why don't I give birth to them first?" Wandering around?”
Chen Kan was telling the truth. These three little brats were indeed spoiled by him. Compared with the other well-behaved and stern children of the Ming Dynasty, these three little brats had very out-of-the-box temperaments.
However, Chen Kan did this intentionally.
In his opinion, children should behave like children.
At a young age, he was serious and solemn, like an antique. That was not elite education, it was the product of failed education.
Chen Qia had gained the upper hand, and no longer mentioned the matter of testing the knowledge of the three little guys. He turned to look at Chen Kan and said, "In this case, there will be Lord Lao."
Chen Qia finally realized that the three little guys were playing him like a fool.
But this was his own decision, or he was reminded by Chen Kan. Although he couldn't help it, he didn't have any objections to the three little brats.
Chen Kan had already experienced the Lantern Festival in the north last year, and he was quite familiar with it this time.
The servants of the Hou Mansion prepared clothes to keep out the cold, a snowmobile, and some snacks.
Chang Ning took the three little ones 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 considered unique in Beijing, not to mention that Chen Qia is not the kind of person who likes liveliness. Compared to the lively bobsleigh competition, Chen Qian guessed that he might prefer the elegant ice lantern street.
The two of them were walking among a group of huge ice sculptures. Zhang Dong led a few guards to isolate all the tourists who were pushing towards them. The two of them held paper umbrellas and strolled in an elegant manner.
Chen Qia stared at these ice sculptures with his eyes wide open, and couldn't help but marveled: "They are really miraculous workmanship."
Chen Kan nodded and said with a smile: "You can't see such beautiful scenery in the south of the Yangtze River. The north has a tradition of storing ice since ancient times. These are just part of it. More ice has gone into the ice cellars of various companies."
While the two were chatting and laughing, they walked to a row of ice houses. Even though it was winter, there were many foods made of ice in the ice houses.
Chen Kan put a money bag in front of him, looked at a shop selling popsicles made of sugar water, lined up six big boys and said, "Here are two small popsicles."
The waiter took the copper coins with a smile, took out two tiger-shaped popsicles from the ice cellar and handed them to Chen Kan. He said with a smile: "Guest, there are various pastries and hot drinks in the shop. Please come in and take a rest." .”
Hearing this, Chen Kan turned to look at Chen Qia: "What do you think, Mr. Chen?"
Chen Qia nodded, walked in and said, "Make a pot of tea and bring some special snacks."
"Okay, you two wait a moment."
The two of them walked in and found a table to sit on. Chen Qia couldn't help but marveled: "I've heard that the savages in Mobei have the tradition of building their houses with ice, but I never expected to see it in Beijing."
Chen Kan, a man with a golden sword, sat down opposite Chen Qia. Hearing this, he couldn't help but chuckle and said: "There are many curious things in the world. I also heard that there is a religion in the West that casts stones for courtyards and houses, which can last for thousands of years." .”
Chen Qia stopped and said, "It doesn't matter if we don't mention the place where we grow hair and drink blood!"
"hehe!"
Chen Kan chuckled lightly but didn't say much.
Scholars are so stupid that they think that the Ming Dynasty is the center of the world and other places are barbarian lands. If they want them to accept other civilizations, unless this civilization can be assimilated by the Han civilization, they will always be arrogant.
Chen Kan just followed their words and mentioned them casually.
Anyway, with the advent of the Age of Discovery, exchanges between the East and the West will become more frequent sooner or later. Even if they want to exclude them, the people who have benefited will not agree.
There was no fire in the ice room, but its warmth was no less than that of the warm spring-like Marquis Mansion.
The two of them drank a pot of tea and talked a lot without realizing it.
When Chen Qia was about to refill the second pot of tea, a boy suddenly walked into Bingwu, came to the two of them and cupped his hands and said: "Two adults, my master has invited me."
Chen Qia rolled his eyes at Chen Kan and asked, "Who is it?"
Chen Kan looked the boy up and down, then smiled and said: "Creditor!"
"Credit?"
Chen Qia looked suspicious, and then asked: "Go and take a look?"
"Let's go!"
After saying that, Chen Kan came to the counter to pay, but was told that someone had already paid.
Chen Qia said with a smile: "To show your courtesy for nothing is either adultery or robbery."
The two young men stood respectfully beside the two of them, neither saying who their master was, nor showing any expression towards the comment that the two were either traitors or thieves.
"lead the way!"
Chen Kan waved his hand, and the boy immediately trotted forward and led the two of them to a carriage.
Chen Kan got straight onto the carriage, followed closely by Chen Qia.
The young man drove the carriage toward the restaurant upstream of the Jinshui River.
Familiar places and familiar people. This time, Zhang Guan did not sit quietly and wait for Chen Kan and Chen Qia, but stood at the door of the restaurant with a wry smile on his face.
It seemed that someone was still clearing the scene, because Chen Kan did not find anyone else in the restaurant except the restaurant staff.
"It's my fault that my lord has been working for a long time."
Chen Kan jumped off the carriage and greeted Zhang Guan with a smile.
Chen Qia and Zhang Guan were also old acquaintances, so when he saw Chen Qia, Zhang Guan's face flashed with confusion for a moment.
Didn't it mean that Chen Qia had died in the fire in the Jinyiwei Prison? Why would he still appear here?
But Zhang Guan was a smart man and quickly figured out the connection. He couldn't help but laughed at Chen Qia and said, "I don't know that Brother Shuyuan is here. I am rude."
Chen Qia bowed his hands to Zhang Guangong and stopped talking.
Zhang Guan didn't care when he saw this, he just stretched out his hand and said: "Master Hou, Brother Shuyuan, please!"
Chen Kan nodded and stepped into the door with his hands behind his back.
It's still the elegant room from last year, but this time, there is one more person.
Chen Kan came to sit down in the private room, and said with an unintentional smile: "I just returned home today, and I received an invitation from Master Zhang without thinking. Master Zhang is quite well informed."
Zhang Guan was stunned for a moment, 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.
The fact that Zhang Guan was monitoring the Hou Mansion was not beyond Chen Kan's expectation. What he meant by this was just a casual knock.
Chen Qia, on the other hand, suddenly became confused when he looked at Zhang Guan after hearing Chen Kan ask this question.
He thought that Chen Kan would have no taboos when he arrived in Beijing.
Now it seems that it is different from what he imagined.
But after a moment, he couldn't help but feel pity in his eyes when he looked at Zhang Guan.
He was spying on Chen Kan and was caught by him. Based on Chen Kan's temperament, he could already conclude that this person would not end well.
The three of them sat down with different thoughts. Since their table was the only one in the entire restaurant, the food was served quickly.
But few people used their chopsticks much.
Chen Kan and Chen Qia were not hungry now because they had eaten enough at home, while Zhang Guan had something hidden in his mind, so he had no appetite.
As a result, the atmosphere suddenly became a little weird.
Finally, it was Zhang Guan who couldn't help but speak first: "Master Hou, now the construction of Beijing City has been basically completed, and the amount of cement used has gradually decreased."
Before Zhang Guan finished speaking, Chen Kan waved his hand and interrupted: "It doesn't matter, no matter how much or how little cement is used in Beijing, since I said that it will be provided in full for free, I will not break my promise."
"This is not what I mean."
"That's not what it means. What does that mean?"
Chen Kan looked at Zhang Guan with a smile, which made Zhang Guan feel a little numb.
Now facing Chen Kan, he really didn't know what to say.
Before today's banquet started, he had been mentally building up for a long time, but when he saw Chen Kan, he still felt a little ashamed.
Seeing that he was speechless, Chen Kan was not in a hurry.
He already knew what Zhang Guan was looking for when he came here. It was just for the reputation of royal cement.
A year later, Chen Kan estimated that he could no longer withstand Zhu Di's pressure.
After all, he sold the title of Royal Queen for the price of a piece of cement in Beijing. Zhu Di would be in trouble if he didn't hurry up.
You must know that perfume and soap bring millions of profits to Zhu Di every year, but they cannot be named as royal.
Facing Chen Kan's half-smiling gaze, Zhang Guan gritted his teeth and finally explained his purpose of coming today.
"What I mean is that in the future, I can purchase the cement provided by the Marquis to Beijing City at the market price."
