Hu Changan smiled slightly and said, "I think that this furnace can be raised and then drummed into hot air, so that the efficiency of ironmaking can be accelerated." ”

What?

Raise the furnace and drum in hot air?

Everyone was a little confused.

These two methods are completely foreign to them.

Ma Shi was the first to step forward and asked, "Hu Shilang, I don't know what the purpose of using these two methods is?" ”

At this time, Ma Shi had already shaken off his previous high-minded appearance.

The current Ma Shi can be said to be humble, and he can't be more humble, so he almost offered Hu Changan.

Hu Changan heard Ma Shi's question, and said with a slight smile: "The purpose of using blast furnace to make iron is to fully react with the particles in the air. ”

"We can load raw materials such as iron ore and coke from the top of the blast furnace into the blast furnace, and use a hot blast furnace to blow hot air into the blast furnace from the bottom to help the coke burn."

"When the coke reacts with a particle in the air that is blown in, it can get particles that can react with iron ore."

"When the raw material settles in the blast furnace, it meets the rising gas and reacts to form pig iron."

Ma Shi was also a little dazed when he heard this.

He never imagined that he would be able to sprinkle raw materials from the stove, nor would he ever think of pouring hot air into it to help with production.

However, with Hu Changan's miraculous skills just displayed, all the craftsmen respected Hu Changan.

Although they couldn't understand it, it didn't prevent them from believing Hu Chang'an.

Thus, the matter of renovating the iron-making furnace of the Ministry of Industry was finalized.

Hu Changan handed over the design drawings drawn in advance to Manager Jiang, and then walked out of the workshop.

It's not too early now, and it's time to go back home and prepare for coal mining.

Hu Changan took a leave of absence from Xue Xiang, the secretary of the Ministry of Industry, and rode back to the mansion.

Hu Fuzhong is peaceful.

Seeing that the young master was back, everyone saluted one after another.

Hu Changan hurriedly nodded to these subordinates, and then summoned Steward Chen in.

"Steward Chen, please come with me to Yaxing."

"Yes."

So Hu Changan and Steward Chen rode their horses and ran towards Yaxing.

In the tooth row, it is still a familiar lively scene.

This time, when the little guy in Yaxing saw Hu Changan, he was obviously much more enthusiastic than before.

Now doing business in Yingtian City, who doesn't know the famous name of Hu Mansion?

Twenty thousand taels of silver a month!

This is a number that no one dares to think of, but I didn't expect this Hu Changan to do it!

Everyone, can only sigh that the afterlife is terrifying.

Hu Changan waved his hand at the little guy and said, "I wonder if there is land for sale in Gaochun County?" ”

"Well, yes, yes." The little guy said diligently, turned around and took out a large map, which detailed all the land that the tooth store was selling for Hu Changan to choose.

And Hu Changan also sat down unceremoniously, took a sip of the tea, and carefully selected it.

Before coming, Hu Changan had already redeemed the "Daming Coal Mine Daquan" in the system.

The current Hu Changan has no shortage of worship points at all.

A large number of worship points come into the account every day, and Hu Changan has long been numb to numbers.

Some books and other things are basically just bought and bought.

In the "Daming Coal Mine Encyclopedia", each underground coal mine is marked in detail.

However, it is a pity that the south is not a coal-producing area, and there is only one small coal mine in Gaochun County.

But for Hu Changan, this is also enough.

After all, the industrial system of the Ming Dynasty has not yet been fully established, and the amount of coal used is very small, and a small coal mine is enough to solve the urgent need.

Hu Changan looked at the map and carefully compared and selected.

Finally, Hu Changan was overjoyed.

Got it!

Unexpectedly, where the coal is located, there is a barren mountain!

Bought it, bought it.

Hu Changan did not hesitate to beckon the little guy to come and pay.

After signing and drawing, Hu Changan had another barren mountain under his name.

The little guy looked at Hu Changan's appearance and was quite puzzled.

This barren mountain has been hanging in their tooth shop for several years and has not been sold.

There are no villages nearby, and they can't be planted, but the area is large, and it's just a shame to abandon the chicken ribs of a tasteless piece of food.

Unexpectedly, it was bought by Hu Changan.

Thinking of the wasteland that Hu Changan bought before, the little guy couldn't help but think about it.

Could it be that this is the secret of the big guy's success?

Xiao Wu hurriedly revealed the news to his peers.

Soon after, among the merchants of Yingtian City, there was a small-scale rush to buy wasteland.

But at the moment, Hu Changan has no idea that he has caused a farce.

After getting the title deed, Hu Changan ordered Steward Chen to quickly mobilize some strong men to go to the newly bought hill to open up the wasteland.

......

The next day happens to be a rest day.

Hu Changan took a group of tall men to a hill in Gaochun County.

When everyone saw this, it was simply that the second monk was confused.

What did Young Master Hu bring them to such a remote place for, did he want to open up the wasteland here?

An experienced man glanced at this small mountain bag and frowned slightly.

The soil on this mountain is really not very good.

Not only is it impossible to grow rice and wheat, but even the best fruit trees are difficult to take root on this hill.

Does Young Master Hu want them to plant things on this mountain?

It's a waste of time!

It seems that Young Master Hu is still too young, he was cheated of money in vain and bought a small mountain bag that can't grow anything.

However, Hu Changan didn't know what everyone was thinking.

Hu Changan jumped off the horse, took out a shovel from the truck behind him, and said to everyone: "Everyone, in the next few days, please dig mountains here." ”

"There should be something black that can be dug up on this mountain, which can be lit with fire."

"If you can't dig in the ground, you can choose to dig deep in the cave."

At this moment, everyone was stunned.

What?

Young Master Hu actually asked them to dig something?

Can black combustibles be dug up in the soil? Isn't that ridiculous!

A bold man even said directly: "Young Master Hu, you shouldn't be playing us, how can you dig up such a thing in the soil?" ”

"And the mountain is so big, it's not a matter for us to dig aimlessly like this!"

Hu Changan listened, just smiled slightly and said: "I said that if this mountain can be dug up, then it will definitely be dug up, you don't have to worry about this." ”

"I will send someone to supervise the work, as long as you are not lazy, I will give you a day's wages for every day of digging, you just dig."

Hu Changan is also powerless about this problem of the man.

The map only told him that there would be coal in the mountain, but it didn't tell him where the coal was!

At present, there is only more manpower, so let's dig it up first.
