Traveling through Great Qin: Father Qin Shihuang!

"This is the teaching building, and inside it is the classroom for the young students. Because there are not many people in Zhuangzi, it is relatively simple!"

"Is this still called crude?"

Ying Zheng couldn't complain.

The construction method of this private school is different from most of the buildings that Yingzheng has seen, and it can even be said to be unheard of.

A general house is basically composed of many independent rooms.

As for Zhao Che's house, it seems that a huge room was directly built and then separated.

The outer wall is painted with a layer of white paint, which looks simple and clean, simple and generous.

Moreover, there are many windows on the wall, all of which are made of crystal clear glass, allowing sunlight to fully shine in.

Through the glass, you can see small rooms one by one, and different signs are hung on the door of each room.

Not to mention the planning inside, the appearance alone is very high-end.

"Boom boom boom!"

Ying Zheng walked to the outer wall and hit it a few times with his fist.

"Che'er, what is your house made of? It seems very solid!"

Ying Zheng said with some surprise.

The surface of the wall is smooth, thick and solid, but it is not the effect that any kind of construction material Ying Zheng has seen can produce.

"Dad has a good vision. This building is made of reinforced concrete. It is absolutely reliable in terms of its sturdiness. I originally planned to build a three-story high-rise building, but I don't have much concrete output, so I temporarily built the first floor. , but enough."

"RC?"

Ying Zheng was taken aback, as if he had heard this before somewhere.

"By the way, the bridge!"

Ying Zheng had a flash of inspiration and remembered the bridge construction guide that Zhao Che had given him earlier.

At that time, Yingzheng wanted to build the bridge on it, but was told by Zhao Che that there was no reinforced concrete, so he gave up temporarily.

"Cher, could it be that you have already researched that reinforced concrete? Can it be manufactured on a large scale? Can you build bridges?"

Ying Zheng quickly asked.

"The research is naturally done, but the output of steel bars is still low. The main reason is that the current iron smelting technology is so bad that the progress of steel bars is far behind the consumption. However, concrete is very simple and can be used to build bungalows. not bad."

"Oh? How does this concrete house compare with adobe bricks?"

"adobe?"

Zhao Che pursed his lips. In his eyes, the earthen bricks produced by Daqin were of poor quality, the kind that would break when touched.

When Ying Zheng saw Zhao Che's eyes, he almost understood what he meant.

"Is it easy to produce with concrete? How much does it cost? Can it be used on a large scale?"

When Ying Zheng heard that the concrete could be used to build a house, a bold idea suddenly came to his mind.

If this concrete is really as powerful as Zhao Che said, maybe in his own hands, it can play an even more powerful role.

"The production of concrete is very fast, and the cost is much cheaper than that of earth bricks. Moreover, the quality of earth bricks produced by Daqin is too poor. I have a way to produce more durable bricks, which can be combined with this concrete. , enough to repair the city wall.”

"How did you know I was going to build the city wall?"

Ying Zheng was taken aback for a moment, he had just had this idea, and Zhao Che actually brought it up on his own initiative.

"Huh? Do you really want to build the city wall? Where is the city wall?"

Zhao Che was taken aback for a moment, he just said it casually.

"You said this concrete is so cheap and easy to use, how about we use it to build the Great Wall?"

"Pfft! Build the Great Wall?"

When Zhao Che heard this, he almost didn't spit it out.

The Great Wall is the most legendary building in the history of China, and it is even called the Dragon Back of China.

Of course, when building the Great Wall, Yingzheng used a lot of labor and resources, which became his most criticized black spot.

However, if concrete is really used to build the Great Wall, it seems that it is not impossible.

The service life of concrete in later generations is about 100 to [-] years.

But if the concrete is not forcibly removed, there is no problem in preserving it for thousands of years.

For example, in ancient Rome at the same time as the Great Qin Dynasty, some people were actually building houses with volcanic ash and other materials, which were basically similar to cement.

In the era after more than 2000 years, those buildings in ancient Rome are still very well preserved, which shows that concrete buildings can be preserved for a long time.

"It is possible to build the Great Wall with concrete, but the key question is, why do we build the Great Wall?"

Zhao Che pondered for a while, and then asked such a question.

"Of course it's to defend against the attacks of foreign races on the frontier..."

Ying Zheng suddenly got stuck at this point.

The original intention of building the Great Wall was to resist alien races, but the problem is that now that the Great Qin Dynasty is so powerful, as long as Ying Zheng orders it to go down, those alien races can be wiped out at will, so what's the point of building the Great Wall?Resist ghosts?

"It seems that you understand, Dad, so I won't say more."

Zhao Che smiled. The best defense is offense. After you have conquered all the enemies who dare to invade you, there is no need for defense.

Zhao Che, as a time traveler, let alone a system, came to this world, not just to overthrow Daqin and build a stronger country.

"However, sooner or later, concrete will be popularized. Houses built with concrete not only reduce costs and speed up construction efficiency, but are also durable and have good thermal insulation performance. It is worth promoting."

"Okay, I'll listen to you!"

Ying Zheng nodded, stopped talking, and was led by Zhao Che to continue to visit the teaching building.

"This is the classroom where young students attend classes."

Zhao Che pushed open the door of the first classroom, and what he saw was a clean, tidy and bright classroom.

The floor of the classroom is also plastered with cement, and tiles are also laid. The floor is wiped clean, and even the shadow of people can be reflected.

"Cher, this is..."

Ying Zheng felt like a bumpkin who had just entered the city. His magnificent Xianyang Palace could be said to be the most luxurious building in the world, but compared with Zhao Che's construction here, it felt like it was lagging behind by many grades. .

Of course, Yingzheng's worth is only a matter of decoration. When it comes to architecture, there is naturally no place in the world more luxurious than Yingzheng's Xianyang Palace.

"The thing on the ground is called a tile. It is waterproof and moisture-proof when laid on the ground, and it is also resistant to dirt and easy to clean. After all, the classroom is a place for teaching and educating people, so it is natural to keep it clean."
