Use mobile phones to teach the ancients to do infrastructure

"Do you know what cement is?" Chen Bai's voice was clearly agitated.

Qi Zheng: "..."

Looking at those students, a group of several people, each with a pile of mud in front of them, was stirring vigorously with a small shovel, and one of the students was asked to record something while stirring.

He is familiar with this scene. Every time the college conducts an experiment, it will be divided into experimental groups. During the experiment, any changes will be recorded.

It's just...it's obviously a pile of mud, what's there to study?

How is it different from the ignorant children playing in mud on the street?

Chen Bo said, "Most of the roads we drive are dirt and gravel roads with potholes and difficult maintenance."

"And like the streets paved with stone slabs in the city, it is difficult to mine the stone, and cutting the stone is even more labor-intensive. With such a large cost, there will still be uneven roads."

Qi Zheng: "..."

Could it be that even the streets they went to the capital were not flat?

It is really impossible to imagine what the flat road Chen Bai said would look like.

Chen Bo continued, "But with the cement in front of us, all the problems are no longer a problem. The cost of cement is low, the transportation is convenient, the production is simple, and the scope of application is also very wide..."

Looking at Chen Bo who was talking eloquently, Qi Zheng couldn't hold back and asked, "Could the cement you're talking about be...these mud?"

It's really hard to imagine, Chen Zifu meant to use this mud to make roads, so that people and horse-drawn carriages can walk on such muddy roads?Just by imagining such a scene, one knows how weird it is.

Chen Bo also laughed. Indeed, to introduce a new thing, he just explained it in this way, which is really exhausting. According to other people's imagination, I don't know what it will be.

Chen Bo said, "Come with me, and I'll take you to see the finished product."

These days, he led his students to make cement, and he was not just working on the formula, but also made some experimental products.

As a result, Gan Xin, who was playing with mud, stood up shyly, waving his hands, "Don't look at mine, don't look at mine, mine is just out of proportion, when I adjust and adjust, I will be able to make a good cement road... ..."

Make other students laugh.

"The roads built by Gan Xin and his team are full of potholes and meat eaten by rats..."

Gan Xin kept denying it, "It's just that I didn't adjust the water ratio properly, everything else is correct..."

Chen Bo didn't go far with Qi Zheng, because the experiment place was nearby.

There are many roads there, each of which is only about 50 meters long, and the quality of each road is also different.

"Your Highness, I am the one who repaired this one."

Without Chen Bo's introduction, some students have already pulled Qi Zheng to show off.

"On... Please ignore the small holes on the top, it's because the cement is not mixed well..."

There are some problems with the roads, some are even cracked, and some potholes are beyond recognition...

But with so many white roads, Qi Zheng was stunned for a long time.

Even if it's a bad road, it's better than the mud road they used to make their way to officialdom. "Are these built with the mud you just bought?"

The corner of Chen Bai's mouth twitched, and he corrected, "It's cement."

"Your Highness, please look at this one over here." Chen Bo pointed to one of them.

This one should be the most successful, whether it is the proportion of the formula or the process of construction.

The flat concrete road, except for some jagged corners, is completely the same as tofu blocks.

"Look at the smoothness. Is it better than the cobblestone road we went to the capital?"

Not only is it good, but its value is integrated. No matter how flat the stone slabs are, they are also artificially punched out. On the slate, you can still feel the shaking.

Qi Zheng stepped up with some surprise.

Chen Bo continued, "Before the cement is mixed with water, it looks like sand, which is very convenient for transportation, but once it is mixed with water, it can be shaped into any desired shape, such as the road we see now, waiting to dry After that, it will form such a hard block with extremely strong load-bearing capacity, at least the horse-drawn carriage will run on it, and it will be difficult to cause damage.”

Not to mention horse-drawn carriages, even more cumbersome cars are no problem at all. In this way, if the cement roads are well maintained in ancient times, they will be more durable than in modern times. No matter how busy the ancient times were, it is impossible to compare with the congested traffic of modern times environmental.

In fact, it doesn't need to be said by Chen Bo, Qi Zheng has already felt the advantages of this road with his feet.

"The roads built with good cement are as milky white as they are now, beautiful and generous."

"Your Highness, imagine what it would be like if I worked hard to build such concrete roads."

Compared with the current potholes, I don't know how much maintenance costs I have to invest every year, it must be a world of difference.

Of course, it is too much work, and it is not possible with the current financial resources and manpower.

However, it doesn't cost much to think about it.

Qi Zheng's eyes lit up, and his mind was full of criss-crossing white jade dragons, and then he pointed out the key point, "How much does this cement cost?"

Chen Bo laughed, and moved closer to Qi Zheng, because it involved a recipe issue, and it was impossible to disclose it to others.

"As your Highness can see, the material with the largest proportion of cement is fine sand. We have a lot of rivers, and the sand beside these rivers actually meets the requirements. You only need to pay attention to reasonable mining. The main cost is on the contrary. On transport."

"The rest of the ingredients are relatively troublesome and need to be mined, such as..."

Chen Bo mentioned several chemical components, which materials need to be mined contain these components.

Fortunately, Qi Zheng took Chen Bai's chemistry class, otherwise it would be like listening to heavenly scriptures.

"As long as large-scale mining is formed, in general, the cost of building a cement road is higher than that of the previous mud-rock road, but it is far behind the cost of building a stone road, but the quality of the road can be improved by a thousand times. times..."

"I can give you an approximate budget later."

In fact, without a budget statement, Qi Zheng could also calculate an approximate price based on what Chen Bo said. The light in his eyes flashed. He probably understood why Chen Bo was so excited when he talked about cement just now. From now on, it is likely to change the habit of Dagan road construction.

Roads are very important to a country.

Chen Bo continued, "Although the price of cement is reasonable, it is impossible to renovate roads in various places under Daqian's current situation, so I plan to use it in the construction of our new fiefdom."

Anyway, new roads have to be built in the fief, which happens to be put into use, and serves multiple purposes.

"And there's more to cement than that."

"We mainly use stone buildings and wooden buildings, but the windproof and moisture-proof ability of the houses has always been insufficient, resulting in serious corrosion of the houses by wind, rain and humidity, and the new houses built have to be repaired in less than a few years. refurbished."

"We only need to adjust the cement formula a little bit, and it can be used to fill the gaps between stones and wood, etc., to achieve a certain purpose of wind and moisture resistance..."

Of course, the main thing is to build roads. This is the road planned by Chen Bo for the construction of the fief.

Qi Zheng suddenly said, "Why do you let a group of students experiment with cement in the hall, and let people see it?"

This Chen Zifu, does he know how precious and valuable the things they have produced now are.

Let's talk about Chen Zifu, smart is smart, but when it comes to some things, he is always a little less guarded against others, and he feels quite careless.

Chen Bo was taken aback, "Others looked at it, and they probably couldn't make it without a specific formula. Even if some materials are mined, they can't be used directly, so they need to be processed a little..."

As for the way the students record their assignments, it may be difficult for anyone other than the academy to understand.

Qi Zheng interrupted directly, "That can't be seen by others."

Then he took people and surrounded the piles of mud, and the guards looked serious.

A group of students waved their shovels, blinking their eyes: "..."

What's wrong?And let so many people watch them play mud?

The others were even more puzzled. It was just a group of urchins playing in the mud. How could this battle look like something important happened.

Qi Zheng said, "Isn't there an open space behind the college? I'll have someone tidy it up a little and it should be usable. In the future, the college will carry out research like this in that open space. I'll send someone to protect it."

Chen Bai nodded. The open space that Qi Zheng mentioned should be the place where he used to raise turtles. Because no one took care of it, few people went there.

Qi Zheng asked, "Didn't Mo Qianji of the Mo family build the fief with you, why didn't he see others?"

Chen Bai smiled, "Since I drew a fief plan for him last time, he hasn't come out of his room for several days except for necessary things such as eating."

Qi Zheng was stunned for a moment, Mo Qianji is a direct descendant of the Mo family, and his attainments in architectural ingenuity can be said to have reached a very high level.

What kind of plan did Chen Zifu give him to make Mo Qianji study so hard?

Qi Zheng actually looked forward to what his fiefdom would be like.

Chen Bo accompanied Qi Zheng into the academy.

In the elevator, Qi Zheng suddenly said, "Last time I asked you to come to the Prince's Mansion every day to learn swords from me, why didn't you come? Look at your sword skills, what a mess."

Chen Bo straightened his body calmly, and then said with a look of surprise, "Did Your Highness tell me so? I guess I was careless at the time, so I didn't hear it."

Damn, he is still waiting to be his second generation ancestor, what kind of sword to learn, although the meaning of ancient swordsmanship and modern swordsmanship is completely different, modern swordsmanship is for performance, and ancient times, because there are only cold weapons, so the use of cold weapons Played to the extreme, it can be said that the ancient swordsmanship is really specially used for fighting, which is very interesting.

Although Chen Bo was also quite interested, but looking at Qi Zheng's appearance, he was going to urge him to practice sword every day.

Moreover, how can there be a subject who asks the prince to train the sword every day? Although he wants to be a favorite, but if this honor is passed on, it may not be as simple as a favorite. What kind of rebellious officials and thieves who are disastrous to the country and the people, who are arrogant and arrogant.

Qi Zheng's status is different now, and I don't know whether Qi Zheng really doesn't know, or if he doesn't know, whether he realizes this or not.

All he needs now is to give him enough face on important occasions, such as arranging him a good seat, so that he can show everyone how much he is valued.

But if he just refused, wouldn't it be too ignorant of flattery in Qi Zheng's opinion?

Chen Bo was also worried, and he didn't expect that Qi Zheng, who used to frown when he looked at him, would now take the initiative to teach him how to learn swordsmanship, and he didn't know which muscle was wrong.

Chen Bai thought for a while, and continued, "Besides, I am not concentrating on building a fief for Your Highness. I have a heavy responsibility, and I can't spare myself."

Qi Zheng replied, "A combination of work and rest."

Chen Bo: "..."

This is what he himself often says.

Qi Zheng continued, "Besides, who is urging you to rush to work? Someone thinks that you are slow in building and will ask you to blame?"

Chen Bo: "..."

Chen Bo was stunned for a long time without saying "this is not appropriate".

In the end, he said tactfully, "I didn't worry about His Royal Highness being made the crown prince. I'm busy with state affairs, so I don't have time to teach me how to practice swords without talent. The trick is the same, how about showing it to His Highness after I have practiced it? The instructor of our Tingwei Mansion is also a well-known swordsman..."

Qi Zheng suddenly narrowed his eyes and looked at Chen Bo, as if he was observing something, making Chen Bo's hair stand on end.

For some reason, Chen Bo couldn't help swallowing a mouthful of water, what's going on?This deadly atmosphere?

Chen Bai performed a kind of ability called survival instinct to the extreme, his body was clever, and he hurriedly said, "Of course, I am flattered that His Highness is so important. From now on, no matter how busy I am every day, I will go to His Highness's house to learn swords. Luo Luo, learn the Bafang sword style to perfection, and promise not to embarrass His Highness."

He felt that if he didn't say a few words like this, he was afraid that blood would be splashed on the spot the next moment.

This Qi Zheng is getting more and more strange.

How to put it this way, it’s like I’m kind enough to treat you as a donkey’s liver and lungs, and I won’t give it to you when I throw it in the trash can.

Chen Bo blinked his eyes at Qi Zheng very "sincerely".

Only then did Qi Zheng look away, "Don't forget again."

Really, what kind of coach from Tingwei's mansion, can you compare him with him?In Chen Zifu's eyes, his personal teaching is not as good as a coach?

Chen Bo heaved a sigh of relief, and secretly glanced at Qi Zheng's emotionless expression. Could it be that he had read it wrong just now?

Was Qi Zheng angry just now?

But why?He showed his obvious humility, teaching him how to learn the sword was simply a waste of time.

Chen Bo sighed, only pay attention to himself in the future, don't let others think that he is charming, and take up the precious time of the dignified prince for a little thing.

When the elevator stopped, Chen Bai was going to take Qi Zheng to find Mo Qianji to see his fief planning map.

In the end, he knocked on the door, and Mo Qianji greeted him twice in the closed room, but there was no reply.

Chen Bo shook his shoulders, "You saw it too, it's in this state."

Chen Bo is not an architect, so the drawings he draws are completely different from architectural construction drawings. What he draws are more like renderings, such as a house, which is a beautiful house without any construction lines.

So after Mo Qianji got Chen Bai's drawing, he was converting it into a usable construction drawing.

It's just that he didn't expect that Mo Qianji would be out of control like a demon.

Chen Bo can only think so, maybe a person with a craftsman spirit is like this.

Chen Bo said, "It seems that we have to wait for His Highness to come to see the plan next time."

It is impossible for him to draw another one now.

Qi Zheng didn't care, Chen Bai thought that Qi Zheng came this time to see the planning of the fiefdom construction, but now it seems that he didn't, and he didn't know what the other party was thinking, he was completely unpredictable people.

Now that the students are playing in the mud below, Chen Bai is still a little embarrassed to be alone with Qi Zheng, "How about playing chess online?"

Chen Bo and Qi Zheng are playing chess.

Downstairs, a group of students were also playing chess with others.

Originally, Ruohong watched Chen Bai enter the academy thoughtfully just now, "Young master of Shangjing, Bai? A person who has reached a dead end has miraculously reached the position of the current number one son of Shangjing in a short period of time, and I What this person most disbelieves in is miracles, and all miracles are nothing more than the veil that hasn't been unveiled yet."

"What an interesting person, and interesting people are often the best pieces."

In the end, he was muttering, and found that something tugged on his sleeve, and when he looked down, he saw a small head, and the younger sister's head on the forehead was particularly conspicuous.

"Chess pieces? Do you know how to play chess?"

"Why don't we play chess"

Chen Xiaobu has been a little drifting lately, his eyes are flickering, and he turns around. He knows this person, Ruohong, the former prince of Yan Kingdom, was once known as the first prince of all countries. When he went to Beijing to watch the excitement, Saw this guy once.

If he wins the opponent in chess, he, Chen Xiaobu, will cheat, and he has to brag to his classmates every day that he has won the first prince of various countries.

Ruohong looked at Chen Xiaobu's flickering eyes, he was also taken aback, and then the corners of his mouth raised, if he saw it right, this kid... is actually digging a hole for him?

It was the first time he met him so blatantly, digging holes for him face to face, which was quite interesting.

And this child should be Chen Zifu's younger brother, so it really didn't take much effort to get here. .

Glancing at the tower, he didn't know what to think, but actually found a place to play chess with Chen Xiaobu.

Lan Ruoyun next to him frowned. The first prince of all countries actually agreed to play chess with a naughty boy?

For some reason, he was not surprised at first, but frowned. Ruohong couldn't be such a boring person, but what meaning could there be?

Chen Xiaobu's eyebrows turned crescent into a smile, "How about we play backgammon? I just learned it too, it's very simple."

This guy plays backgammon with others every day, because he can play it anytime and anywhere, so he just learned it.

Ruohong glanced at it, then nodded amusedly, "Tell me the rules first."

Thus, a weird gamble began.

However, Chen Xiaobu was surprised, because no one who only learned the rules could beat him, but now he met him.

Chen Xiaobu frowned, and set up a trick, but he didn't win.

Ruohong shook his head amusedly, the children nowadays are really...

But at such a young age, he is actually like a clever ghost, with a flexible mind.

Chen Xiaobu pouted his mouth, "It's not that I'm capable of downloading it, but I'm capable of downloading our college's computer."

But before he finished speaking, Gan Xin, who saw the whole process, squeezed in, "His Royal Highness Yan Guoruohong, do you dare to play a game of chess with me? Go to Shangjing Gan Shisan."

It was the first time that Ruohong's identity was revealed.

Ruohong was also a little surprised, it was such a little guy who caused heavy losses to the Ba Kingdom and gained a great reputation, now in all the countries, there are probably portraits of this Gan Shisan circulating, fearing that he will enter the country to inquire about news.

Ruohong nodded thoughtfully, no matter how you look at it, he is just a weak child.

Gan Xin had already taken out the chess, and began to explain the rules to Ruohong, "My chess is much more complicated than Chen Xiaobu's backgammon, and it is also much more difficult to play. On the border of the Chu River on the chess, every game is equivalent to a big battle. There is no doubt that I will personally lead the army to fight, and I am not that little rascal Chen Xiaobu, I have been practicing chess for some time, you should be careful..."

Gan Xin began to introduce the chess pieces one by one, and introduced its rules.

Ruohong didn't care about it at first, it was no different from a real battle of leading troops, to put it so mysteriously, it was just playing chess.

Just listening, Ruohong glanced at Gan Xin in surprise.

There are distinct types of arms, and the walking rules of each chess piece contain the characteristics of this type of arms. This chess actually shows the military science in a strange way.

A game of chess is different from a war. It actually moves the smoke of the battlefield directly onto paper. Although this chess may not be as flexible as a real battlefield, it is definitely enough to give people some inspiration and ideas, and it can even be called a strategist treasure.

It's so easy to take it out and play against others.

He suddenly understood a little bit why all the schools of thought gathered here suddenly. At least from this chess game, it can be seen that this Yunshang Academy has something that can attract military strategists.

After Gan Xin placed the chess pieces and explained the rules, he looked at Ruohong.

Ruohong nodded, "Let's begin."

Gan Xin was stunned for a moment, most people might not even remember the rules after listening to it once.

Gan Xin also performed a formal etiquette, and this was the beginning, because he felt that he had taken advantage of it, and his chess skills had been practiced for a long time.

Just doing it, Gan Xin was stunned.

There were quite a few other students gathered around to watch the fun, and they could also play chess, but they were not as good as Gan Xin.

As a result, Gan Xin almost lost to Ruohong, who was playing chess for the first time.

After a while, Gan Xin said, "The first prince of all countries really deserves his reputation, Gan Xin lost."

After finishing speaking, he added, "It's not that I am inferior to your Highness in Yunshang Academy, it's just that Gan Xin's skills are not as good as others."

Since it is a game of chess, even if it looks a little casual, it is still gambling with people with the halo on it.

Although they are small, they also represent the strength of Yunshang Academy.

It's really embarrassing to play chess with people who have never learned this kind of chess in public, and lose all of them.

These students actually began to think about the reputation of the college, and they really regarded themselves as part of the college.

"If it is played against our college's computer, no one should be able to win."

Ruohong moved his eyes, who is this computer?

But before he could think about it, two more students came up holding a strange chessboard.

"Shang Jujiu of Yunshang Academy and Shang Zhizhou asked His Royal Highness Ruohong for advice."

Ruohong: "..."

This Yunshang Academy really has some strange and good things, "This is He Qi?"

"There are nineteen horizontally, nineteen vertically, criss-crossing, encompassing the world and the world, and all the ever-changing ones, this is the game of Go."

I don't know when, there are more and more people watching chess. The black and white chess pieces and the dotted chessboard have caught the eyes of many people.

This competition is easy to say, but one side is Yunshang Academy, and the other side is Ruohong, the former first prince of various countries. This is a bit different, so there are so many people watching.

Chen Xiaobu was also a little dumbfounded, he just drew random pictures on the ground with others, and played backgammon, how did it become like this?
