After Qin Shihuang Lived for A Long Time, All Human Beings Were Looking for Me Madly

"Please immortal teacher to teach Da Qin!" Meng Tian and Qin Shi Huang hurriedly asked Su Tian for advice.

As long as the transportation capacity is improved, the benefits to Da Qin are obvious.

As far as Wang Ben's expedition to the Western Regions is concerned, the materials that he will return in the future are now the biggest problems of Qin Shihuang.

Xisu, or the Hexi Corridor, is too long.

With the current supply of grain and grass, if you want to transport the grain to the Western Regions, I am afraid that there will only be less than half of the grain left.

That's it, under the premise of streamlining the escorts and using firearms to guard against.

Su Tian smiled lightly and explained: "Well, there are actually several aspects to improving the capacity, which can be regarded as several steps."5

"The first is to build the road. At present, Daqin has no way to get the asphalt, and that needs to be developed together with the fuel.

"The easiest way is to calcine cement, you only need to build a kiln, and I will give you a plan for this.

"Cement?" When Meng Tian heard the name for the first time, he was a little confused and didn't understand what it meant.

Su Tian smiled, pointed to the road at the door and said:

“Cement is these things that make hardened pavements, and specific 07 stones are burned into ashes in a high-temperature furnace. 35

"With water and gravel, it only takes 1 day to lay on the ground to become so strong! Of course, it needs to be sprinkled for maintenance in the next few days."

hiss~

Qin Shihuang and Meng Tian became slightly excited while being shocked, as if they had discovered a new great land.

So solid in one day?

Wouldn't the speed of Daqin's paving be several times faster?

What's more important is that the current dirt road in Daqin, even if it is repaired, is more difficult to walk.

The reason why the car is coaxial is to make the wheel resistance less in the two pressed grooves.

But all this, with this kind of ying road, everything becomes simple.

"I don't know how much the cement can be produced? Is it convenient to obtain materials? Meng Tian asked the questions he is currently concerned about.

During the Shang and Zhou dynasties, there were materials that could harden pavement.

It's just that it is very difficult to obtain materials, and it is generally only used in palace construction, or imperial tombs and other places.

"It's very simple, you can get materials on the spot at any time, and even the transportation can be omitted." Su Tian smiled when he heard his question.

Meng Tian was shocked when he mentioned the material for calcining cement.

Is it a limestone that can be seen everywhere? Add some auxiliary materials such as clay, iron ore, coal mine, etc., and break it and burn it twice?

Su Tian said to Qin Shi Huang again:

"Your needs are not really big, you can burn them manually."

"I won't ship any mixing stations and equipment to you, it's useless if there is no electricity there.

Qin Shihuang was mainly used to connect the roads between major counties, so to be honest, it is not used too much for the time being.

Even if the road was repaired all the way to the Western Regions, and a road was only accessible by carriages, it would not cost much to Da Qin of Binuo.

"It seems that this trip is worthwhile!" Meng Tian continued:

"This cement can be called a fetish. With this thing, won't it be faster to build a city in the future?"

Qin Shihuang didn't even think of this, it turns out that there is such a wonderful effect.

The role of cement is great, Su Tian asked them to go back and think about what else they could do.

Then go on to say:

"Okay, after talking about this road construction, it's about improving the carriage!"

"At present, the two great transportation artifacts, the car and the train, cannot be done by Da Qin for the time being. They can only work on the carriage.

Meng Tian wondered, how else could the carriage work?

"It's enough to change it to a 4-wheeled carriage, the capacity can be doubled, and the road is easier to walk, which can indirectly increase a lot.

Four... four-wheeled carriage?

Qin Shi Huang also showed a strange expression.

China was not without four-wheeled carriages in ancient times, and even more sixteen-wheeled carriages appeared.

But until it was replaced by trains, it did not become popular.

The point is that the four-wheeled carriage is not practical for the roads of China.

Dirt roads are driven in the two grooves pressed out, even if it is a stone road for a long time, there are still two grooves.

The biggest problem of China's four-wheeled carriage is that it is particularly difficult to turn in this groove.

It needs high horsepower to pull, so when there is such a four-wheeled vehicle, at least 2 or more horses are used to pull the steering.

Vigorously perform miracles, that's what it means.

Obviously, Su Tian is not talking about China's primitive single-board 4-wheeled carriage.

"It's not the same, now Daqin's iron and steel production has reached the standard, and the steering of the four-wheeled carriage I'm talking about is no longer a problem. 99

Su Tian saw that their expressions were misunderstood, and explained with a smile.

Then the two people took a look at the picture and the original, and it was very simple to make 4 rounds of the original veneer.

It was changed to two front and rear boards, and the middle was linked by a steel shaft.

In this way, the steering problem can be solved perfectly, and the capacity of the same horse can be at least doubled.

"It turns out that it's as simple as adding a shaft..."

After understanding the operation, Qin Shihuang understood what Su Tian meant.

Sure enough, technology is productivity.

"Then I will go back and let the domestic craftsmen start to build cement roads and make four-wheeled carriages. 35

"When will I, Daqin, have the other ways to improve the capacity that the immortal master said?"

After Qin Shihuang got the formula for firing cement and the design of the four-wheeled carriage, he was concerned about several other ways.

"Naturally, the next one is water transportation. Together with large waterways such as the Yellow River, Huai River, and Yangtze River, artificial canals are built.

hiss

Build artificial canals?

Qin Shihuang and Meng Tian were stunned when they heard it. How much manpower was needed to dig out the water conservancy connecting the north and the south?

They can naturally understand the canal. As early as the Spring and Autumn Period, the concept of the canal was already in use for the convenience of irrigation.

Qin Shihuang was actually no stranger to building water conservancy. During his reign, the Zhengguo Canal was built to irrigate the grain in the Guanzhong area.

But the Zhengguo Canal could not be transported by water, and it took tens of thousands of people and 10 years for the length of only 300 miles.

Now it is necessary to build a 2,000-mile-long ultra-wide river channel that can transport goods from north to south. Qin Shihuang's mind seems to be unable to turn around.

Su Tian naturally knew that building a canal was not something that could be accomplished in a short time.

Even the Grand Canal of the Sui and Tang Dynasties was connected by Yang Guang on the basis of the existing part of his predecessors, and it took a huge amount of manpower to connect it. It can be said that it was replaced by Guozuo.

"Of course, this is the next stage, and the Qin Dynasty's national power does not support it for the time being~" Su Tian said with a smile, this is what you asked first.

"Oh, what the immortal master means, can I see my Daqin connecting the north and south water conservancy in my lifetime?"

Meng Tian took a deep breath and seemed to hear some extra meanings from Su Tian.

Su Tian explained:

"Of course, I estimate that after you have built the cement road to the Western Regions and popularized horse carriages, you can start preparing for the canal."

"So soon? Isn't the immortal master comforting me?"

Qin Shi Huang didn't believe that Da Qin could repair this terrifying canal so quickly.

"Of course not. If you want to quickly repair the canal, I can provide you with some equipment support. 99

"Then more, you may have to rely on Daming..."

Su Tian smiled, modern equipment can support some, and then there is strong support from Chongzhen.

what?

Qin Shihuang and Meng Tian were stunned, thinking that what happened to Chongzhen?
