Returning to the camp, Chu Jungui started cutting the two newly processed animal skins. The two goats were hunted, and the cactus branches did not make any contribution this time. Chu Jungui had discovered that the creatures in the real dream had a strong influence on the cactus.
There is a natural sense of radiation. Every time a branch is taken out, the surroundings are full of chickens and dogs, and all birds and beasts stay away. But the explorer does not have this ability.
Chu Jungui cut the animal skins and tied them to wooden sticks to make a primitive blower. At this time, a taller and larger smelting furnace had been built next to the original smelting furnace, with piles of
The proportion of charcoal is far higher than that of the original furnace, and 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 is far higher than that in the real world. The temperature of this new furnace should be over 1500 degrees, which is barely enough for steelmaking in the real world, but here, I'm afraid,
Still can only refine ordinary metals.
At this time, there is a small pile of ore next to the new smelting furnace. There are about dozens of pieces, but it is not iron ore. These ores have been screened out by Kaitian one by one. There is some copper, but more of them are various types of ore.
Rare elements.
Chu Jungui put the ores into the furnace, ignited it, and when the furnace temperature rose to above 1,000 degrees, he began to manually control the blower to provide air, and then stared at the fire to judge the temperature. Kaitian was beside him to assist with temperature control.
It projects a model of the smelting furnace and uses different colors to mark the furnace temperatures in different areas of the furnace.
Both it and Chu Jungui could only see the outer flame, but there were still a few iron bars inserted in the furnace, and one would be pulled out from time to time. The temperature at the end of the iron bar was the temperature of the furnace core. After obtaining data several times in this way, Kaitian's
The smelting furnace model becomes 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 slower.
In this way, relying on the primitive means of sight and manual blower, Chu Jungui achieved precise control of the furnace temperature, with a temperature difference of 3 degrees.
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 temperature of the furnace, gradually climbing to 1500 degrees. At this time, a large amount of non-metallic materials began to melt and flow out, mainly silicon. When all these flows were finished, Chu Jungui started to increase the pressure of the drum.
The wind blew out the flames from the furnace mouth for several meters. Under this brutal and brutal pressure, the temperature of the furnace gradually rose to 1700 degrees!
This time, a small ball of molten liquid flowed out, and after condensation, it had a dark silver light.
Chu Jungui exhaled a breath of hot air and retracted his hand. This primitive furnace was just like this and could not meet higher requirements. However, his real gain was not the small ball of titanium-based alloy, but the final product in the furnace.
The remaining slag and some rare elements with high melting points are all in the slag.
Finally, after cleaning the furnace, Chu Jungui recovered a ball of about 5 kilograms of slag. Chu Jungui broke open the slag, crushed it, and then observed the particles. First he used the spectral field of view, then switched to the magnetic field field of view, and finally judged the slag particles.
It contains a lot of rhenium, niobium, tantalum and tungsten. The content of these elements in the slag actually exceeds 20%. If it were in the real world, it would be a rare super rich ore. And these ores can be seen everywhere in real dreams, they are ordinary stones.
.It’s just that they are relatively scattered, and no mineral veins have been found yet.
The purification of each of these elements is a major subject, but Chu Jungui's demand for purity is not that high, and the amount required is not large.
The second smelting furnace consumes much more work than the first one dedicated to iron smelting, but it is actually used only this time. At this point, local metallurgy is basically over. If you want to separate and purify these high melting points
Rare metals cannot be produced with this kind of furnace.
However, since the amount is not large, Chu Jungui has his own way.
He ground the slag into fine powder, then spread it flat on an iron plate that had been polished and sealed with a layer of wax, and waved his hand to the sky.
Kaitian sighed and covered it, and saw the slag particles floating up and entering Kaitian's body, and then fine powder continued to fall. Those particles became smaller and smaller, until they became particles invisible to the naked eye.
With Kaitian's cell-level phagocytosis ability, it will eventually eat away all the impurities attached to the surface of the metal particles and turn them into waste and throw them away, leaving behind high-purity metal particles.
An hour later, a thick layer of gray-white powder appeared under Kaitian. Chu Jungui poured the powder away, and then Kaitian sprinkled a piece of metal particles. Most of these particles were hundreds of molecules in size.
, basically can be used directly.
Chu Jungui had already turned the smelted copper into three thin copper plates, and then gave Kaitian a design drawing.
Kaitian swallowed a mouthful of rare metal powder, and then wrapped it around a whole copper plate. The copper plate made by Chu Jungui was not large, with a size of 30*30m and a thickness of about one millimeter.
After Kaitian wrapped the copper plate, the entire copper plate slowly changed. Kaitian continued to swallow some copper, and then secreted new metal to replace the original copper.
This time the processing was much slower. It took a full 2 hours before finally spitting out a piece of 20*20 metal mesh. The mesh was very fine and the whole body was dark yellow. It was actually a copper alloy mixed with rare elements.
Chu Jungui was very satisfied. He put the copper mesh into a special small furnace, connected one end to an electrode, and then lit a fire in the furnace. After burning for a while, Chu Jungui picked up the electric needle and approached the other electric needle.
, there was a snap, and an electric spark lit up between the two electric needles.
"It's done." Chu Jungui put down the electrode with satisfaction.
Directly converting thermal energy into electrical energy is a basic operation for humans. Everyone knows the principle, but there are no processing conditions in the real dream. Chu Jungui, on the other hand, directly took away the sky and used it as a biorefining 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 started processing the parts, preparing to turn the prototype small furnace into an original model of thermal energy power furnace. After installing a three-layer conversion network, this small power furnace
The power can reach 10KW, which is a bit weak, but with electricity, there are more possibilities.
The night passed in the blink of an eye.
There was a small smelting furnace in front of Chu Jungui. It was actually only the size of a bucket, and the furnace cavity was about the same as a large teacup. The difference between this pocket-sized smelting furnace is that it uses electricity, and the temperature inside the furnace exceeds
2500 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 is carefully polishing this crystal the size of a fingernail. Although he only holds the original
file, but the machining accuracy is no worse than that of high-grade machine tools.
Finally, the crystal was processed and turned into an extremely complex polyhedron. Chu Jungui put it in front of his eyes, carefully observed the inside, then sighed and shook his head slightly.
"Did it fail?" Kaitian asked.
"Don't worry, it's barely usable." Chu Jungui raised his head and looked at the sky. A ray of morning light had appeared in the sky, and a new day had arrived.
Chu Jungui sighed and said, "It's already the 8th day. It seems that our progress has fallen seriously behind."
Chu Jungui shook his head slightly, threw the red crystal to Kaitian, and said, "Try charging it."
Kaitian transformed into a human form again, and placed the crystal in the position of his right eye. Then he saw the core of the crystal light up, and a thin, hot beam of light shot out, instantly piercing an iron plate.
At this moment, there was a small commotion at the Federation Moonlight Unicorn Base. The reason was that an explorer returned on his own initiative and brought back a lot of information with a specially enhanced memory area.
He was half lying in the medical cabin, and countless data were being transmitted from the neural interface to the main brain, and then clear images were projected on the big screen.
A ruin appears in the image, like a small village, but only a broken wall remains. There are roughly seven or eight houses in the ruins, and civil structures, fired pottery, etc. have appeared. Behind the village is a cave, inside
There is a cave in the sky. 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. In the center is a person pointing to the sky, and where he points is a complex pattern composed of dots and lines.
This pattern is very abstract, but when it fell into the eyes of many scientists at the research center, it aroused exclamations of surprise.
"This is a molecular structure diagram! Compare it quickly to see what substance it is!"
"The match has no result, it is a completely new structure diagram!"
"Experiment immediately, edit atoms according to the structure diagram, and see what you can create!"
The next few murals have a similar style. The second picture shows that people have made weapons like spears and shields and are fighting wild beasts.
The third mural shows people building houses and sculptures.
The third picture shows people trying to build a high tower. It is only half-built, but according to the proportions in the picture, it is already dozens of times the height of those humanoid creatures. Under normal circumstances, primitive humans cannot build such a tall building.
Or even if it is built, it will 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, and there is a lack of knowledge in mechanics and other things.
The last picture is above the altar, which is also the largest and most colorful one. There are hundreds of little people in the picture, worshiping a plant in the center. It looks like a cactus.
In front of the chief scientist of the research base, four murals extracted from memory were placed, and they were displayed dozens of times, giving a feeling of majesty and vastness that towered over the sky. The reason why the explorer used up a precious opportunity to return was because of research
The center requires that once large-scale civilization relics are discovered, they must be reported back.
At this time, an assistant came over and said: "We have successfully compiled a substance based on that molecular diagram. It is an alloy, and its composition is... The characteristics are 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 can build such a tall tower."
The assistant's voice softened subconsciously and said: "Did these people really exist?"
The chief scientist frowned and said nothing. Reason told him that this was not true, but his intuition vaguely pointed in another direction.
