Chapter 157

Ren 8000 looked at the iron mountain in front of him. He really had some doubts. Is this really a natural product?

Compared with the mine, Ren 8000 is more willing to believe that this is a huge meteorite iron.

Unless you don't know how many billions of years ago, such a large piece of meteorite iron hit the ground, and then after years of crustal changes, the huge basin here should have been turned into a plain, and this meteorite iron became Damo mountain.

In any 8000 hearts, this possibility is greater than natural formation.

Otherwise, this iron mountain is too unconventional.

"Can you make some holes here?" Ren 8000 pointed to the part of the mountain wall protruding from his head and asked the valley dome. His fist should be at least a foot and a half deep.

Six or seven meters above Ren 8000's position, the rock wall began to bulge outward, about three or four meters.

It should be that height has been difficult to mine.

However, if you drill a few holes in that place and then use explosives, it is likely to blow down a large piece.

After all, he is not specialized in blasting. He can only guess where the blasting effect is better.

"Lord Fucheng, although I don't know your plan, I really can't get such a big eye out. At most, I can only make a hole deep in my fist. No matter how deep it is, I have to dig next to it." Gu Qiong said with a puzzled face.

Ren 8000 frowned after listening to this. Gu Qiong's words should be true, but in this case, explosives will hardly have any great effect.

At present, if it is on the earth, there are many ways to think of, such as cutting it piece by piece with acetylene.

But most of them need either electricity or gas tanks. Like acetylene, I can only bring one bottle at a time, and I have to bring it directly here. Otherwise, I'm afraid I'll have to blow it up in the middle of Dayao's road.

However, if you bring it here, your secret will be exposed in the eyes of people other than the female emperor, which is unacceptable.

"Take me to have a look around Damo mountain." Ren 8000 pondered for a long time. Let's look around first. It will be dark for some time now. At least I can look at the iron mountain.

In the following time, they rode along the foot of Mount Damo for a distance before coming back. Ren 8000 found that the mountain was really a huge meteorite iron as he thought, because the structure of the mountain was completely different from the surrounding land. All the iron ores were gathered on the mountain, and only a few plants grew on it, It is full of weeds and other living plants. It should be that the dust that has fallen for many years has accumulated on the mountain, forming a layer of surface soil.

"Lord Ren, what can I do?" On the way back, Tao Jiyuan asked Ren 8000 with a frown.

"Hmm? I have some ideas, but can I do it? I have to try." Ren 8000 was startled from thinking, looked up at him and said.

"That's great. Over the years, countless people have tried to speed up the iron ore mining in damoshan. They can only use manpower to mine a little. If Ren has a way, it must be a great achievement." Tao Jiyuan smiled.

"If I say mining here, it's better to go out and grab it quickly." Gu Qiong muttered on one side.

Ren 8000 rolled his eyes. Isn't this nonsense. Most of the time, looting is faster than mining. The question is, is it that easy?

When they returned to the camp, it was nearly dark, and the prisoners coolies came back in droves, waiting around a few barrels in the middle of the square to make broth, but few people spoke. They had passed many years, and few new people would be sent.

Ren smelled the smell of broth from a distance of 8000. "Good food!"

"If they don't have enough to eat, they don't have the strength to work. After all, this iron mountain has less strength and can't chisel a small piece in a day."

Ren 8000 nodded.

Gu Qiong had cleaned up a wooden house for him, and his dinner was also broth, but he added a little more wild vegetables and two grains. Even Gu Qiong eats this on weekdays. There are no shops in front of the village and behind. Except for the people who send meat on weekdays, even individuals can't see it and can't get anything else to eat.

After a meal, Ren 8000 had a good rest all night. When he woke up the next day, he called Gu Qiong and Tao Jiyuan to his room: "I have an idea. I should try it. Pile a lot of wood to Damo mountain, and then pour water on it. After thermal expansion and contraction, cracks will appear on those iron, which should make it easier to chisel the mountain."

Although Ren 8000 said so, he was not optimistic about this method. After all, it also takes a lot of manpower to transport a large number of timber. Although it is a little easier than now, if you add the manpower for cutting timber and transporting timber, as well as the time consumed by burning mountains and washing with cold water, such efficiency is still too low. I'm afraid it's not much better than now.

He had another idea in his mind, that is, after going back, he made a large number of mirrors and concave mirrors, adjusted the angle of the concave mirror, aligned it with the mountain wall, and then reflected the sunlight on the concave mirror with the mirror.

In this way, the focused light reflected by the concave mirror can melt the iron into molten iron in a very short time, and then it is much easier to mine and separate it.

"Heat expansion and cold contraction? What do you mean?" Tao Jiyuan didn't know Ren 8000's idea, but he was very interested and curious about his statement.

"We can demonstrate it." Ren 8000 pulled the people out of the house.

"Start with a fire." When Ren 8000 ordered him to go down, Gu Qiong immediately called a man to get the wood as Ren 8000 ordered.

A moment later, a fire rose. Ren 8000 picked up two stones and asked people to bake them on the outer flame of the fire with two iron cones.

Others looked at what he told them to do and wondered what he was going to do.

A moment later, Ren 8000 estimated that it was almost time, so he asked people to throw the stone into a bucket of water prepared next to him.

First, some bubbles appeared, and then after a few minutes, Ren 8000 reached in and fished out the stone. There were several cracks on it.

Ren 8000 showed the stone to several people. Others had not found any problems, but Tao Jiyuan suddenly realized: "so it is."

This very normal natural phenomenon is not discovered, but no one summarizes it, and no one investigates the reason. Therefore, there is no concept of thermal expansion and cold contraction. No one wants to apply this situation to Damo mountain.

"Why?" Tao Jiyuan suddenly realized and asked curiously.

"Because an object will expand when it is heated, even if you can't see it with your eyes, it is expanding. And an object will contract when it gets cold. If this expansion and contraction occurs in a short time, this change will occur. Not only the stone, but also the iron."

Ren 8000 probably explained that if he said something about molecules, the other party must not understand.

Tao Jiyuan thought on his face, while Gu Qiong stared and asked, "Lord Ren's idea is to burn this Damo mountain?"

"Just burn one place." Ren 8000 looked around. Although there was no vegetation on Damo mountain, there were other mountains around.

Let someone cut some wood and burn the mountain first. Although the efficiency is still very low, you can try it. It can speed up the mining progress.

When you go back and study how to make the concave mirror, you will be able to completely solve the problem of Da Mo mountain mining.

Unfortunately, the 40 kg TNT brought by myself may be useless.
