Just watch the kung fu in Yingcheng.

The coal in the fire finally burned.

"Look, the black stone is burning!"

Suddenly, the man next to the fire screamed.

Woke everyone else up completely.

In an instant.

Whether it was Guo Huaiyi or Feng Shijie, or the people led by Du Laowu, they all looked at the fire for the first time.

I saw the coal on the fire with yellow-red flames.

There was smoke up there.

But the temperature in the vicinity is rising rapidly, and you can clearly feel the heat of coal burning at a distance of two or three feet.

A whole barrel of coal burned quickly on top of the fire.

This made everyone look at the burning coal in amazement like a curious baby.

"Actually, it really burned."

"The heat of the burn has obviously warmed up the place."

"This is coal?"

Feng Shijie let out a voice of extreme surprise.

I can't help it.

Feng Shijie squatted next to the fire, cautiously trying to touch the red puff coal with water.

But he seemed to feel the temperature of the coal, and before he could get close to it, he was retracted by the hot handle.

"Indeed, this seems to be much, much higher than the heat of charcoal."

Feng Shijie couldn't help but sigh in amazement.

After participating in the whole process of searching for coal, and seeing that there is a lot of coal underneath the ground.

It's for him.

It was deeply shocked.

Seriously, coal is many times more convenient than charcoal.

The production of charcoal is also a costly undertaking.

That's it.

Many people can't afford to use charcoal in winter, and even if logging is repeatedly banned in autumn and winter, there are still many people who cut down indiscriminately, all so that they can heat their homes in winter.

That's it.

Many people spend the winter in the cold.

And now.

This coal.

If there are abundant numbers, the people's winter will really be over.

Right next to the burning coals.

The faces of the young men were burned red and red, but none of them stood far away, eager to get into the fire.

"Childe, how did you do this!"

Guo Huaiyi stared at the burning coal in great amazement, the red bumps were very hot at first glance, and he couldn't help but ask.

It's really this scene, it's so magical.

Especially for those who have studied black stones...... Coal for him.

He couldn't figure it out.

Why did he light it at the beginning, but now the coal is on fire.

"Oh, you don't understand, maybe, one day someone will find out about the problem." Yingcheng smiled, and did not directly tell Guo Huaiyi to answer, but said: "Now, you just need to know that coal will gradually replace the status of charcoal, and that's it!" ”

Yingcheng didn't have so much leisure to explain the problem of the burning point to Guo Huaiyi.

This issue is not a complex one, though.

The burning point of each thing is different.

Anthracite burns at 500 to 700 degrees, bituminous coal at 400 to 505, wood at 150 to 300, and at a temperature of 800 to 1,000.

It is normal for the same temperature to ignite wood but not coal.

Once the combustion point is explained, it involves physics such as neutralization and heat of combustion.

If it is more complicated, it will involve the problem of the chemical heat of reaction.

Why does combustion release heat.

This requires a whole set of theories, and someone has to study and understand the basic theories.

Arguably.

He believes that after using coal to forge more things, someone will understand the key to this.

The problem of the burning point can solve many, many things about elemental separation!

That's physics!

Similarly, the problem of coal desulfurization must always be studied, and it cannot be all up to him!

Finding problems and solving them is the normal operation of this society.

Feng Shijie didn't understand it after repeated research, so he reluctantly got up, came to Yingcheng's side, and said:

"At this time, the lower officials admired the Great Law Order more and more, and the foresight of the Great Law Order really convinced Feng."

"I'm Daqin, and I've added another artifact!"

"Xiaguan will go to gather the villagers and start digging this area, emptying all the floating soil on the surface."

Let's talk about it.

Feng Shijie turned around confidently and left quickly.

This search for coal can be said to be a full return.

As soon as Feng Shijie left, Du Lao Wu rushed to Yingcheng.

Hehe smiled, and he looked a little shameless.

"Childe, childe, this is it, bounty, grass people......" Du Lao Wu hesitated but firmly stepped forward.

Yingcheng is an existence that he can't hope for.

Even if Yingcheng didn't give him the bounty he promised, he didn't have any way.

I only hope that Yingcheng will speak for granted.

"I promised you, you are indispensable, when I go back, I will go to Feng Shijie to ask for it, just say that I said it from Yingcheng, one hundred gold, not a penny!"

Yingcheng didn't carry a hundred gold, let alone take a hundred gold and hand it over to Du Lao Wu.

Just grab an official and tell him to go on, there is no need to waste time on such a small matter.

"Grass people thank Gongzi for his great kindness!" Du Lao Wu was grateful.

Yingcheng waved his hand, no longer caring about Du Lao Wu, but instructed Guo Huaiyi again: "Send someone back to report to Your Majesty, and bring my report by the way!" ”

Naturally, he does not forget the problem of horses that did not pull carts.

It's not hard to make a choice, either a human or a beast.

Man can't be used as an animal!

"The last general obeys!" Guo Huaiyi quickly received the order and arranged the matter.

"Da Lu Ling, let's talk about it!" Yingcheng was arranging the general direction of many things, but Bai Lang, who was tied up on the side, couldn't stand still.

Yingcheng looked over suspiciously.

"Give the coal here to my Bai clan to manage, and my Bai clan is willing to obey all the arrangements of the son!" Bai Lang said calmly.

It seems that as long as Yingcheng agrees, he can carry the entire Bai clan to Yingcheng.

After listening to this, Yingcheng twisted his head and didn't even want to answer half a word.

The old thing is very clear.

Coal is a profiteering industry that has made countless coal bosses.

The value of coal was seen at a glance.

However, what kind of green onion is your Bai clan!

"It was my Bai clan who was wrong before, and I hope that the prince of the city will not be angry!" Seeing Yingcheng like this, Bai Lang's face turned cold, but he still smiled and said:

"As long as the prince of the city agrees, what does the prince of the city want my Bai clan to do, just ask."

Seeing that the Bai clan would not give up, Yingcheng opened his mouth and said with a smile: "One hundred thousand Yi gold, bring it, the Pinyang Boundary Coal Mine, all of it will be handed over to your Bai clan to operate!" ”

"Take the money to humiliate me, I don't care about all this red tape!"

Bai Lang frowned and said angrily: "Is there really no room for negotiation?" ”

Are you kidding.

100,000,000,000 gold, that's a figure that can't be made up for a hundred Bai clan's entire industries.

Yingcheng shook his head with a smile and commanded Du Lao Wudao: "Dig down that place and see!" ”

Yingcheng wanted to determine how large the shallow coal range was and what direction it was heading.

Although coal was found.

But knowing the entire history of coal mining, he knew that coal mining was a more dangerous thing to do than his other mines.

The shallow layer is fine.

Once the tunnel is mined deep, it is mined 100 meters underground.

A slight collapse, that's a very heavy accident.

Meantime.

Because the location of discovery is next to Qin Zhidao.

If necessary, Qin Zhidao may have to be rerouted, which is all a problem.

Once you've identified a specific location, it's much easier to dig out the coal.

Really.

According to Yingcheng's instructions, Du Lao Wu and his people also dug up coal on the side of the mountain.

"Dig into the valley!"

Digging out the coal again, it was probably more than three feet, and Yingcheng probably understood what was going on, and ordered again.

Du Lao Wu led people to dig in the valley again.

But this time.

Layers of hard rock were dug up, which were sedimentary rocks.

The flat valley floor has a layer of floating soil more than a foot thick on the surface, and under the floating soil is a hard sedimentary rock, which needs to be excavated with a chisel.

In fact.

The site itself is an open-pit coal mine.

But it was covered by wind, sand and dust.

Meantime.

Although the terrain is high, it is a trough compared to before, and a large amount of coal gradually emerges under the pressure of the terrain.

This led to the emergence of coal dug up on the mountain.

Although the valley grows with the topography, it grows more slowly because of the heavy rocks, forming a flat valley topography.

Other words.

These two mountains are the entrance to the underground coal of the entire Pinyang territory.

Digging from here, you can dig out all the underground coal in Binyang.

The reason why you can't find coal anywhere else is because the depth is not enough, and if you dig down hundreds of meters, you can still dig coal.

Got it.

Yingcheng will no longer be explored.

Soon there were young people coming one after another.

One by one, they came with very painful faces.

Look like that.

It must be because he didn't get the bounty.

Lost 100 gold!

How can it not be painful.

Yingcheng naturally didn't care what these people thought.

When a group of people came, they ordered a group of people to start digging the coal seams.

The surface coal mine is much easier to dig.

It's good to encounter a large piece of smashing open.

There is no need to worry about the coal mine.

Slowly.

Next to the Yingcheng fire, more than a dozen tons of coal have been piled up.

Anthracite is coal with a very high degree of coalification, and it is difficult to see the surface layer.

Meantime.

Look at the pile of coals high up.

In his mind, honeycomb coal, coal lumps and other products of coal have been sketched.

Although the population of this era was not as large as that of later generations.

But again, the mining technology is also one thousandth of that of later generations.

Coal is not enough to heat all the people.

And this, honeycomb coal is used with a little money, and coal is used without money, which are two derivative industries.

It can feed a lot of people.

The work of coal mining was handed over to slaves and yi, and the derivative industries were handed over to the people, and this was the social structure under the fifth class and the ninth stream.

Today's late night, Yingcheng no longer feels cold.

It seems to be a psychological effect.

The burning coal warmed his heart, and his body was not cold.

Piles of coal burned around in the open mountains.

The surrounding temperature is also gradually rising, and the cold wind is fighting fiercely.

And at this time.

Xianyang City, inside the Imperial Palace.

The First Emperor, Li Si, Feng Quji, and Meng Yi sat next to a brazier, like a bitter haha, stretching out their two hands to bake the fire next to the brazier, feeling the heat from the coal in the brazier.

The warmth that comes from the pavement.

The First Emperor couldn't help but admire: "This grandson of mine is amazing! ”

Li Si couldn't help but echo and praised: "It's strange to say, Lao Chen has seen this thing many years ago, but it wasn't until this time that he realized that it was actually used like this." ”

"The intelligence of the city prince is really far greater than that of the old minister!"

Meng Yi also exclaimed: "This thing is really a divine object, born between heaven and earth, it is much more crisp than a rock, but it is so convenient and simple to burn, and so warm." ”

"Before, I didn't even find that there were such divine objects in heaven and earth, thanks to the prince of the city!"

Feng Quji also exclaimed: "If this thing is produced between heaven and earth and buried deep underground, it must be more than this, if it is a large-scale mining." ”

"Then it will be much easier for all the people in the world to survive the winter in the future."

"The minister is here to congratulate Your Majesty, with Your Majesty's blessing, my Great Qin will be passed on forever!"

The First Emperor smiled with satisfaction and said, "So, what do you think should be done with this coal mining." ”

Feng Qujian thought about it for a while, and took the lead in replying: "This thing is related to people's livelihood, if it is according to Lao Che's previous thoughts, it will definitely not be touched by private individuals." ”

"However, according to the new Qin law, this property will be partly operated by the government, and partly it will be handed over to individuals to operate."

"However, since this thing is related to people's livelihood, this price must be limited, and how constant this price depends on the cost of mining and the speed of mining."

"The specific details still have to be investigated first."

The First Emperor nodded, agreeing with Feng Quji's way of dealing with it, but shook his head again and said: "This coal appears in Pinyang, as long as the Bai clan is not stupid, he will definitely seek coal mines." ”

Li Si took the order and said: "The old minister is willing to take the order and deal with the affairs of the Bai family, just a Bai family, if it turns the clouds and rain in the Xianyang realm, it will really make the world laugh at the old minister!" ”

The First Emperor nodded and said: "Well, the Bai Clan's merits to my Qin State for generations still can't make it chill, however, we still have to give the Bai Clan a little warning, we can't ignore the national policy in the county and township pavilions because they have meritorious deeds for generations, the Qin State has no fiefdom, and all the meritorious clans must understand this truth." ”

"In addition, Wang Li is going to come down from Daijun and take the Qin Straight Road, it should be fast, send an order to Wang Li, and ask him to bring the horses he needs to Yingcheng!"

"This kid is smart and smart, but his ability to make trouble for others is not small at all, but if this is another official, he doesn't solve the trouble himself, and throws his hand to me to find this trouble, I will never take him lightly."

"Hmph, he's good, he needs five thousand horses of horse-drawn coal, just open his mouth and come, really think this Qin country is his, everyone has to revolve around him?"

Li Si, Feng Quji, and Meng Yi listened to the complaints of the First Emperor.

Look at each other.

What is the specific situation, do you have no points in your heart?

Still complaining here.

If you are really dissatisfied, won't there be nothing to do if Yingcheng is arrested and locked up?

It's good that you don't even give a word of reprimand.

Who would dare not cooperate!
