Everyone's eyes lit up when they heard this.

It sounds like it can be prevented no matter how strong the wind is?

Unless the wind is strong enough to blow rocks as big as wheels and collapse the roof.

And it’s more than twice as simple as building a house on flat land. You don’t even need to build walls, and you don’t have to worry about finding big trees to build beams and buildings.

Although this was their first time hearing about this kind of underground kiln, they had dug the cellar used to store vegetables in winter in Lijiabao. Naturally, they knew how much less effort it would take to build this kind of underground kiln than to build a house.

Everyone looked at Li Chengzhi with burning eyes, admiring them in their hearts:

Lang Jun is indeed a man ordained by God. He can turn decay into magic with just a finger?

Although this was not the first time he was worshiped by these people, Li Chengzhi's face still felt a little burning.

What turns decay into magic is like forging steel, this is the wisdom of our ancestors.

In later generations, this kind of cave dwelling was commonly known as Diwozi, which was specially designed to solve the residential problems in areas with severe geological desertification. It was extremely common in the northwest.

From here, more than 100 kilometers northwest, is Lop Nur, which will later be known as the Jiuquan Satellite Launch Base. Before it was made public, there was only one name there in official documents and private messages: Diwo Castle (pronounced 'Pu')!<

/p>

Founders such as Qian Xuesen and Qian Sanqiang lived in such dens and built atomic bombs and missiles.

Directly west of this, about two hundred kilometers away, is Yumen, which was also called Diwopu in those days. The iron man Wang Jinxi lived in Diwozi and developed the Yumen Oilfield.

Further west, all the way to Xinjiang, there are not too many places called Diwopu along the road, and they are all named after this.

For example, Urumqi's Diwopu Airport...

It felt like Li Zhang was always a little slower than others. Li Song, Li Liang and others were already planning which battalion would cut wood, which battalion would pull clay, and which battalion would dig kilns. Only then did he figure out this "underground kiln"

"What is it?

He frowned and asked abruptly: "There is no wall outside the kiln. If it rains, wouldn't it all flow in?"

Li Chengzhi is absolutely defeated.

Although the weather is dead, people are always alive, right?

He sighed helplessly: "Dams can be built around the underground kiln to block water, or canals can be dug to divert water... As long as there is breath, who can watch the water flowing into their home?"

Li Zhang was stunned for a moment, and in the blink of an eye his face turned purple with embarrassment.

No one had any objections, and everyone unanimously decided to build this kind of kiln.

Then Li Chengzhi told them how to prevent fire and how to prevent carbon poisoning (carbon monoxide) when heating in winter.

After he finished speaking, he heard the sound of horse hooves hitting the ground. Li Chengzhi subconsciously turned his head and saw a horseman running from the north of the camp.

When I got closer, I saw it was Li Cong.

Wasn't Li Cong sent out by Li Song early in the morning to watch the iron manger (old blacksmith) take his apprentice to build the blast furnace?

It has only been half a day. At most, the furnace has just been built and it will be dark after waiting for the furnace to burn out.

Li Chengzhi's heart skipped a beat: Could it be that the furnace exploded?

Otherwise, it would be impossible for Li Cong to come back so early and still be in such a hurry?

Damn it, it’s probably because the clay’s fire resistance isn’t strong enough...

The journey alone would take ten days. Li Chengzhi did not dare to stay here for too long. Naturally, he did not have time to wait for Li Song to bring high clay from Linze (one of the counties under the jurisdiction of Zhangye, more than a hundred miles away).

Then teach the blacksmith how to set up a blast furnace to smelt iron ore.

As an expedient, he asked the old blacksmith to dig some red soil on the river bank, and mixed some graphite into it to use it to burn bricks and start a furnace.

This thing was washed down from the Qilian Mountains, and the content of kaolin in it is not low, so it should be enough.

But who can guarantee that there will be no accidents?

I don’t know if anyone was hurt, let alone how many...

Li Chengzhi's heart sank slightly, and he looked at Li Cong running closer and closer, feeling suspicious in his heart.

I thought what I heard would be bad news, but looking at Li Cong, his face seemed to be filled with joy?

"Lang Jun, the iron juice is out..."

Li Chengzhi was stunned and almost cursed.

What bird eggs are you talking about?

The furnace has not been built yet, and the ore has not been smelted yet. Where will the molten iron come from?

Besides, it’s iron, not wax?

He has not yet taught the old blacksmith how to make coke or add flux during ore refining. Besides, there is no coal in the camp and only a few handfuls of dry firewood. How can he smelt molten iron?
p>

"Lang Jun, it's true..."

Li Cong bared his teeth and smiled so unhappy, "When the furnace was being sealed, the iron man said he was idle, so he threw a few magnets (ore) in to see if they could be refined...
p>

But who would have thought that in less than half an hour, iron juice actually flowed out from the bottom of the furnace... It was real iron juice. Even the iron waiter exclaimed a miracle, and his disciples almost knelt down..."

Li Chengzhi was shocked: Is it true?

Have you seen a ghost?

He was puzzled.

"Go and see!"
