Da Qin: The First Emperor was reborn and made me the crown prince at the beginning

Chapter 299

Then the work of the entire library began to get on track.

In this case, Yingchen's eyes began to focus on other aspects.

Among them, it was at this time that good news came from Yanmen County.

But Yingchen had been thinking about how to push the border of Great Qin to the north~.

Sometimes, we have to understand a question.

Sometimes, it's not that our ancestors were unwilling to expand, but that they couldn't do so.

In the era when there was no coal for heating, especially during the Qin and Han dynasties.

With the Great Wall as the boundary.

The area south of the Great Wall is also very cold in winter, but it is still barely able to be carried down.

However, after crossing the Great Wall, once the grasslands of the northern land and the northeast region get cold, the temperature may reach more than minus 30 degrees.

In this case, if you don't have enough heating equipment, you can't survive the winter.

This situation is called "white plague" in the grassland!

So this is also the reason why in all dynasties, the peoples on the grassland will do their best to enter the Central Plains.

Can't live!

It is precisely because the conditions for survival are extremely difficult that in this case, they will desperately attack the Central Plains!

On the other hand, because of the difficulty of survival, the cold-blooded and murderous side of the people on the grassland has been cultivated.

Because for the people on the grassland, from the moment they are born, they face various challenges to survival.

This extreme living environment can cultivate soldiers who are not afraid of death.

It can also cultivate beasts whose animal nature is greater than human nature!

It is precisely because of this that Yingchen has been thinking about how Daqin can completely solve the grassland problem.

Among them, the most important thing is undoubtedly coal!

With coal, it is possible to heat the heat in the winter.

In the bitter cold of more than minus 30 degrees outside, the tent is tightened, and then the coal is lit, and the indoor temperature can be increased by more than ten or twenty degrees, which is undoubtedly a paradise life for the vast majority of grassland people.

So since the victory of the Northern Expedition, Yingchen has been searching for coal.

As a person who traveled from the afterlife, he naturally knew that in the entire East Asian region, the place with the most coal was in Yunzhong County.

There is a very famous coal mine here, Datong Coal Mine!

This is also the largest coal mine in China!

Therefore, Yingchen has always asked the children of the Mo family to bring professionals to explore here.

Although the coal in Yunzhong County can also be called the best coal mine in the country.

But even then, it is more than thirty meters above the surface.

This kind of distance is also difficult to find in the Qin Dynasty, where productivity is extremely backward and the level of exploration is not high.

And Yunzhong County is not small.

It is not so easy to find coal in a short period of time.

Of course, under Yingchen's golden finger, recently, there has finally been a breakthrough in this matter.

In Yunzhong County, the children of the Mo family led a group of soldiers to dig a large coal mine.

When the news reached Xianyang, Yingchen was immediately overjoyed.

At the same time, the technology that Yingchen has been pinching in his hands and signing in from the system can finally come in handy.

This is coal washing technology!

Coal is not the first thing that Yingchen has discovered its burning and heating functions.

There is no shortage of smart people in the world.

But the coal dug directly from the coal mine is called raw coal! (Read violent novels, just go to Feilu Fiction Network!) ）

Raw coal has an extremely serious flaw.

That is, raw coal will have many impurities in the mining process and in itself.

When these impurities are burned, they release toxic gases!

These gases can be much more serious than the carbon monoxide poisoning caused by our daily use of coal.

So in the beginning, coal was also called toxic carbon.

If it weren't for the complete helplessness, in the case of the need to choose between being cold to death or being poisoned, even in the Tang Dynasty, the people would not use coal for heating.

Now, Yingchen has a way to wash the raw coal and then clean the impurities in the coal, which undoubtedly greatly improves the possibility of the people being able to use coal.

Of course, if it was just to keep the people warm, Yingchen wouldn't care so much.

Crucially, coal is the food of industry.

With coal, Daqin was able to start the first industrial revolution!

But anyone who knows history knows that without the success of the first Industrial Revolution, no British Empire would have been the foundation of the empire on which the sun never sets.

Nor is it possible for Westerners to dominate the world for 400 years or more.

And as a person who understands the future, if Yingchen is just satisfied with being a Ming monarch and holy lord in the feudal imperial era, and does not want to push Daqin into the industrial age, it is undoubtedly short-sighted, and even despicable!

It is as if Kangxi knew that the industrial level of the West was improving rapidly at that time, but he deliberately concealed these technologies and did not let the people come into contact with them.

Kangxi himself can be called a scholar of China and the West, and there are many science and technology in the Western astronomical calendar!

And Qianlong himself knew France.

Even he knew what was going on in France at the time.

But he was afraid that the Han people at that time would learn this kind of thinking, so he deliberately concealed all this information.

This was the greatest sin of the Qing rulers.

Bad!

This is extreme selfishness!

In order to maintain their own or the rule of the Qing Dynasty, they deliberately fooled the people.

Therefore, this kind of thing, Yingchen will never do.

No, the role of coal, the first part is used in cement manufacturing.

You know, if you want to make cement quickly, you need to fire.

When there was no coal, it was basically only possible to burn it with firewood.

Well, now there is coal, and coal burns far more efficiently than firewood.

Therefore, the cost and time of manufacturing cement in Daqin have undoubtedly been greatly reduced.

From this point of view, it is all incomparable, a great credit.

Of course, in addition to this, Yingchen also deliberately made a non-toxic coal.

This coal, in later generations, was called honeycomb coal!.
