After returning to the camp, Chu Jungui began to cut two animal skins that had just been processed. Both goats were hunted, but the cactus branch did not make a contribution this time. Chu Jungui has already discovered that the creatures in the real dream have a natural perception of the radiation of the cactus. Every time the branches are taken out, the surroundings are full of chickens and dogs, and all kinds of birds and animals are far away. But explorers don't have this ability.

Chu Jungui cut the animal skin and tied it to a wooden stick to make a primitive blower. At this time, a taller and larger smelting furnace has been built next to the original smelting furnace. The proportion of charcoal piled in it is far higher than the original smelting furnace. With the addition of a blower, the furnace temperature is bound to be raised to a higher level.

Items in real dreams are generally rich in energy, and the heat energy released by charcoal far exceeds that in the real world. The furnace temperature of this new furnace should be able to reach over 1500 degrees, which is barely enough for steelmaking in the real world, but here, I am afraid that it can only refine ordinary metals.

At this time, there was already a small pile of ore beside the new furnace, about dozens of pieces, but it was not iron ore. These ores are screened out one by one by Kaitian, there are some copper, but more are various rare elements.

Chu Jungui put these ores into the furnace, ignited the fire, and when the temperature of the furnace rose above 1000 degrees, he began to manually control the blower to supply air, and then judged the temperature by staring at the fire. Kaitian is on the side to assist in temperature control. It projects a model of the smelting furnace and uses different colors to mark the furnace temperature in different areas of the furnace.

Both it and Chu Jungui can only see the outer flame, but there are still a few iron bars inserted in the furnace, and one will be pulled out from time to time. The temperature at the end of the iron bars is the temperature of the furnace core. After obtaining several data in this way, Kaitian's smelting furnace model became quite accurate, with an error of no more than 3 degrees.

When the temperature is low, Chu Jungui blows harder, and when the temperature is high, he blows more slowly.

In this way, relying on the primitive means of eyesight and manual blower, Chu Jungui realized the precise control of the furnace temperature, with a temperature difference of 3 degrees up and down.

The furnace temperature was maintained at 1150 degrees for a period of time, and a batch of molten metal flowed out, which was basically copper.

When the copper was almost harvested, Chu Jungui continued to increase the furnace temperature, gradually climbing to 1500 degrees. At this time, a large amount of non-metallic materials begin to melt and flow out, the main body is silicon. When all these were finished, Chu Jungui began to increase the blast, and the flames spewed out from the furnace mouth for several meters. Under this brutal pressurization, the furnace temperature gradually rose to 1700 degrees!

This time, a small ball of molten liquid flowed out, which condensed with a dark silvery light.

Chu Jungui let out a hot breath, and withdrew his hand. This kind of original stove is just like this, and it cannot meet higher requirements. However, his real harvest is not the small group of titanium-based alloys, but the last remaining slag in the furnace. Some rare elements with high melting points are in the slag.

Finally, after cleaning the furnace, Chu Jungui recovered a mass of slag about 5 kilograms. Chu Jungui knocked open the slag, crushed it, and then observed the particles, first using the spectral view, then switching to the magnetic field view, and finally judged that the slag particles contained a lot of rhenium, niobium, tantalum and tungsten. The content of these elements in the slag actually exceeds 20%, if it is in the real world, it is a rare super rich ore. And these ores, which can be seen everywhere in real dreams, are ordinary stones. It's just that they are scattered, and no veins have been found yet.

The purification of each of these elements is a great science, but Chu Jungui's demand for purity is not so high, and the demand is not large.

The second smelting furnace took much more work than the first one dedicated to ironmaking, but in fact it was only used this time, and the local metallurgy basically came to an end at this point. It is impossible to rely on this kind of furnace to separate and purify these rare metals with high melting points.

But since the amount is not large, Chu Jungui has his own way.

He ground the slag finely into powder, then spread it flat on an iron plate with a polished surface and sealed with a layer of wax, and waved to open the sky.

Kaitian sighed, covered it, and saw the slag particles floating up and entering Kaitian's body, and then there were fine powders falling down continuously, and those particles became smaller and smaller until they became invisible to the naked eye.

With Kaitian's cell-level phagocytosis ability, it will eventually chew off all the impurities attached to the surface of the metal particles, turn them into waste and throw them out, leaving high-purity metal particles in the end.

An hour later, a thick layer of gray-white powder appeared under Kaitian's body. Chu Jungui poured the powder away, and then Kaitian sprinkled a piece of metal particles. Most of these particles exist in the size of hundreds of molecules, which can basically be used directly.

Chu Jungui had turned the smelted copper into three thin copper plates, and then gave Kaitian a design drawing.

Kai Tian swallowed a mouthful of rare metal powder, and then covered the entire copper plate. The copper plate made by Chu Jungui is not big, it is 30*30cm in size, and its thickness is about one millimeter.

After Kaitian wrapped the copper plate, the whole copper plate slowly changed, Kaitian swallowed some copper continuously, and then secreted new metal to replace the original copper.

This time the processing was much slower, and it took a full 2 ​​hours before Kai Tian finally spit out a 20*20 metal mesh. The grid is very fine, and the whole body is dark yellow. It is actually a copper alloy mixed with rare elements.

Chu Jungui was very satisfied. He put the copper mesh into a special small furnace, connected an electrode to one end, and then raised a fire in the furnace. After burning for a while, Chu Jungui picked up the electric needle, approached the other electric needle, and with a snap, an electric spark lit up between the two electric needles.

"It's done." Chu Jungui put down the electrodes in satisfaction.

Converting thermal energy directly into electrical energy is a basic operation for human beings, and everyone understands the principle, but there is no processing condition in real dreams. Chu Jungui directly took away the Tiandang Bio Refining Machine and Manufacturing Machine to create the most critical conversion network.

Chu Jungui asked Kaitian to continue processing the remaining two copper plates, while he processed the parts himself, preparing to turn the small prototype furnace into an original thermal power furnace. After installing a three-layer conversion network, the power of this small power furnace can reach 10KW. Although it is a little weak, with electricity, there are more possibilities.

In the blink of an eye, the night passed.

In front of Chu Jungui was a small smelting furnace, which was actually only the size of a bucket, and the furnace cavity was about the size of a large teacup. The difference in this pocket version of the smelting furnace is that it uses electricity and the temperature inside the furnace exceeds 2,500 degrees.

Now the result of the first furnace is in Chu Jungui's hands, it is an irregular red crystal, like a gem. Chu Jungui was carefully polishing this nail-sized crystal. Although he only had a primitive file in his hand, the processing accuracy was no worse than that of a high-grade machine tool.

Finally, the crystal was processed and turned into an extremely complex polyhedron. Chu Jungui put it in front of his eyes, carefully observed the interior, then sighed and shook his head slightly.

"Failed?" Kai Tian asked.

"It doesn't count, it barely works." Chu Jungui looked up at the sky. A ray of morning light has appeared in the sky, and a new day has arrived.

Chu Jungui sighed, and said: "It's already the eighth day, it seems that our progress is seriously behind."

Chu Jungui shook his head slightly, threw the red crystal to Kai Tian, ​​and said, "Try charging."

Kai Tian transformed into a human figure again, placed the crystal at the position of his right eye, and then saw the core of the crystal light up, and a hot, thin light beam shot out, piercing through an iron plate in an instant.

At this moment, there was another small commotion at the Federation Moonlight Unicorn Base. The reason was that an explorer returned on his own initiative and brought back multiple materials with a specially strengthened memory area.

He was half lying in the medical cabin, countless data were being transmitted from the neural interface to the main brain, and then a clear image was projected on the big screen.

A ruin appeared in the image, like a small village, but only a ruined wall remained. There are roughly seven or eight houses in the ruins, and civil structures and fired pottery have already appeared. At the back of the village is a cave with a cavern. At the end is a hall, and at the end is an altar with several weathered beast skeletons placed on it.

There are many murals on the cave wall, one of which depicts several humanoid creatures, one in the middle points to the sky, and a complex pattern composed of dots and lines is drawn where he is pointing.

This pattern is very abstract, but it caused a lot of exclamation when it fell into the eyes of many scientists in the research center.

"This is a molecular structure diagram! Quickly compare and see what substance it is!"

"There is no result for matching, it is a brand new structure diagram!"

"Experiment now, edit the atoms according to the structure diagram, and see what you can create!"

The next few murals are similar in style. In the second picture, people have created weapons similar to spears and shields, and are fighting wild beasts.

The third mural is people building houses and building sculptures.

The third painting is that people are trying to build a tall tower, which is only half built, but calculated according to the scale in the picture, it is already dozens of times the height of those humanoid creatures. Under normal circumstances, primitive humans would not be able to build such a tall building, or even if they built it, it would have to be a structure similar to a pyramid. It cannot be such a thin and long pagoda structure, because the strength of the material cannot be increased. , but also lack of knowledge such as mechanics.

The last picture is above the altar, and it is also the largest and most colorful one. In the picture, hundreds of little people are painted, worshiping a plant in the center. It looks like a cactus.

In front of the chief scientist of the research base, there were four murals extracted from memory, and they were displayed dozens of times. The reason why the explorer used up a precious opportunity to return was that the research center required that once a large-scale civilization relic was discovered, he had to come back and report it.

At this time, an assistant came over and said: "We have successfully edited the substance based on that molecular diagram. It is an alloy with the composition... The characteristic is that the density is slightly lower than aluminum, and the hardness and toughness are similar to steel, but The melting point is only 700 degrees."

The chief scientist looked at the third mural and said, "No wonder they built such a tall tower."

The assistant lowered his voice subconsciously, and said, "Did these people really exist?"

The chief scientist frowned and said nothing, his reason told him that this was not true, but his intuition faintly pointed in another direction.
