Due to Zhao Qian's addition, some equipment, such as the existence of rings, were not displayed in tacit understanding. After arriving at the primitive man's residence, Xiao Wei transported the equipment needed for the research from the space number.

Li Yu was not prepared to keep the existence of robots confidential. Anyway, the current level of robots in the country is not low with the contributions that Li Yu made inadvertently, so confidentiality is meaningless.

Therefore, the installation and moderation of the equipment on site were completed by robots. Li Yu and his team took advantage of this time to visit the primitive people's residence.

"According to the scale of the primitive people, their residence should not be called a village, at least it should be called a primitive town or a city, so that it can meet its development level." Fang Qianmo said to Li Yu.

This primitive town has an area of ​​about five square kilometers, and this area is indeed not small. It is located in the valley between the mountains and the terrain is relatively flat. From a structural point of view, it is roughly divided into two parts, with a fault about ten meters high in the middle. Above the fault is where the upper class live, almost all of which are made of exquisite stone houses, and various facilities are relatively complete.

Below the fault, the house planning is relatively messy and not as neat as the superstructure. However, they look like a more life-like atmosphere, unlike the superstructure, full of religious meaning.

There is also a third part that is not obvious, which belongs to the periphery. Li Yu thinks it is absolutely appropriate to describe it as a shanty town. These three main parts are all separated by a city wall more than five meters high.

In addition, there are Lingsan buildings in the distance, so there is no plan for these, including a bunch of them in the east and a group of them in the west.

"The reason for this city to exist is for special elements." Lin Wanbai looked at the piles of gravel piles piled up in the distance and saw the essence of the existence of this city.

The snow water on the mountains melts and gathers into a river with abundant water. When encountering the city where the primitive people are located, it forms a small impact plain, flows forward, and then forms a waterfall of a large scale.

The snow water flowing down from the mountains has formed a settlement belt of special elements on this small plain for tens of millions of years. Primitive people are like gold digging, sedimentation of ores formed by special elements from rivers.

Lin Wanbai said that this city mainly exists on special elements, and he is not wrong at all.

"By the way, it is possible to naturally form an impact plain in the mountainous area without forming a dam, so it has to be said that the environment of this place is a bit unique." Li Yu also thinks that the terrain here is good.

"Li Yu, I discovered the place where the primitive people made weapons. Do you want to come and take a look?" Xiao Wei stood at the entrance of a cave on the hillside and waved to Li Yu.

Xiao Wei's existence also made Zhao Qian silence. She never expected that the deep-sea organization would have such a powerful artificial intelligence. In her opinion, Xiao Wei could be said to be a life.

Zhao Qian could not have imagined that to some extent, she had guessed the facts. It was not because of Zhao Qian, but mainly because of human understanding of intelligent life. There are many misunderstandings, which is related to the overall level of human civilization.

The weapons of the primitive people were of course the focus of Li Yu and the others. When Xiao Wei discovered the place where the primitive people made weapons, they did not hesitate at all and came to the place where Xiao Wei discovered it.

It can be seen that the primitive people attach great importance to this place. The outer periphery of the weapon manufacturing point is a tall city wall, and there is only a place facing the residence, where there is an import and export of personnel and materials.

If the original man is still there, there should be four more checkpoints here to conduct detailed inspections for everyone entering.

This place, from a distance, seems to be a cave. When you look closer, you will find that it is completely a visual error formed by light.

The place where the primitive people made weapons was actually not a cave, but a huge yard. It was surrounded by high walls up to ten meters thick.

"The productivity of these primitive people is actually not low at all, right? This kind of project is not smaller than the pyramids on the earth!"

Fang Qianmo couldn't understand what these primitive people thought.

When Li Yu came to this place, he temporarily put down his speculation about the behavior of the primitive people. What he is interested in now is how the primitive people made weapons.

But at first sight, Li Yu was a little disappointed.

"What, this is too rough, right?" Lin Wanbai was also very disappointed.

The weapons of primitive people are powerful, so the process of making them should be full of high-tech style, right? Even if primitive people do not have such a level, they should have such a level in the civilization of legacy weapons manufacturing technology!

But after coming to the weapon manufacturing site, Li Yu and the others discovered that the weapon manufacturing process of the primitive people was really primitive.

After the primitive people screened out the rivers for special elemental ores, these ores were sent here for the next step of processing.

The treatment method is very rough. The primitive man put the original ore into a huge stone mortar and used artificial penis to make the penis.

Judging from the situation left at the scene, the whole process should be a process of ten primitive people, using a simple lever to lift a stone pillar weighing about one ton, and like pounding medicine, the raw ore of special elements into pieces.

It is to pound, not to grind, because the special elemental ore has relatively high hardness. If you grind, you cannot easily crush them into powder.

When the cube is fine enough, the cubes are collected and placed in a huge pool, washed with running water, sink to the bottom of the water, and do not merge into the water, and are not washed away, which is the crystallization of special elements with relatively high purity.

These special elements crystallize, after screening and drying, they are poured into a mold and placed in a brick kiln-like kiln for sintering.

You can say that after Xiao Wei's calculations, after a few days of sintering, these modules will be the final product and energy block.

"Is the Primitive Man burning porcelain?" This is the question of everyone in the laboratory.

The energy blocks that come out of the kiln are like transparent glass. The reason is of course that there is no energy in the energy block.

So, the next step is to charge the energy block.

This step is the most like a high-tech place in the entire weapon manufacturing industry. The charging place is a simple fission reactor.

Fission reaction requires the concentration of heavy elements to reach a certain level before it can be carried out. Before entering the interstellar era, there are only a handful of countries on Earth that mastered the purification technology of heavy elements.

Of course, these primitive people did not master heavy element purification technology like the earth, and they did not even master electricity.

So, how do these Yuanru people carry out the fission reaction of heavy elements? Of course, they need to be applied to special elements.

Special elements have good energy absorption properties, so they are a perfect radiation-proof material additive.

In this way, there is no problem in collecting heavy elements. What about extracting heavy elements? It is even simpler. You only need to crush the heavy element ore like a special element raw ore, then mix it with the powder after washing the special element, let it sit for a few days, and then wash it in water.

After this process, heavy elements are perfectly precipitated by special elements and adsorbed on the powder surface of special elements to form reaction core powder.

Haha, there is no problem with nine purity.

Next, the last step for the energy block to be put into use, the sintered energy block is placed in a huge hemispherical kiln like a brick.

In the center of the kiln is a high platform, and there is a pot-like thing placed on the high platform. When the energy blocks in the kiln are all placed, a kilogram of reaction core powder will be placed in the pot.

Next, this reaction core powder will undergo critical reactions like a reactor in the nuclear power department, release energy, and be absorbed by the energy block.
