Returning to the camp, Chu Jungui started cutting the two newly processed animal skins. Both goats were hunted, but the cactus branches did not contribute this time. Chu Jungui has discovered that the creatures in real dreams have a natural perception of the radiation from the cactus. Every time a branch is taken out, chickens and dogs will jump around, and all birds and beasts will stay away from it. 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 stacked in it is far greater than that of the original smelting furnace. With the addition of a blower, the furnace temperature is bound to be raised by a level.
Objects in real dreams are generally rich in energy, and the heat energy released by charcoal is far greater than that in the real world. The temperature of this new furnace should be over 1,500 degrees, which is barely enough for steelmaking in the real world, but here, I'm afraid it can only refine ordinary metals.
At this time, there was a small pile of ore next to the new smelting furnace, about dozens of pieces, but it was no longer iron ore. These ores are all selected one by one by Kaitian. There is some copper, but more of them are various rare elements.
Chu Jungui put the ores into the furnace and ignited it. When the temperature of the furnace rose to above 1,000 degrees, he began to manually control the blower to supply air, and then stared at the fire to judge the temperature. Kaitian assists with temperature control. It projects a model of the smelting furnace and uses different colors to mark the 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 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 slower.
In this way, relying on the primitive means of sight and a manual blower, Chu Jungui achieved precise control of the furnace temperature, with a temperature difference of up to 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 1,500 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 began to increase the blast force, and the flames spurted out several meters from the furnace mouth. Under this barbaric and brutal pressure, the furnace temperature gradually rose to 1,700 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 breath and retracted his hand. This primitive stove is just like this and cannot meet higher requirements. But his real harvest was not the small group of titanium-based alloy, but the last remaining slag in the furnace. Some rare elements with high melting points were in the slag.
Finally cleaning the furnace, Chu Jungui recovered a ball of about 5 kilograms of slag. Chu Jungui cracked open the Shanghai slag, crushed it, and then observed the particles, first using the spectral field of view, then switching to the magnetic field field of view, and finally determined that the Shanghai slag particles contained 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 just 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 science, but Chu Jungui's demand for purity is not that high, and the demand is not large.
The workload of the second smelting furnace was much greater than that of the first one dedicated to smelting iron, but it was actually used only once. At this point, the local metallurgy was basically over. If you want to separate and purify these high melting point rare metals, you cannot rely on this kind of furnace.
But 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 are hundreds of molecules in size and can basically 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 an entire copper plate. The copper plates made by Chu Jungui are not large, with a size of 30*30cm 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 the operator finally spit out a 20*20 piece of 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, so 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. With a snap, 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 understands the principle, but there are no processing conditions in real dreams. Chu Jungui, however, directly used Kaitian as a body refining machine and manufacturing machine, creating 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 power furnace. After installing a three-layer conversion network, the power of this small power furnace can reach 10KW. Although it is a bit weak, 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 tea cup. The difference with this pocket-sized 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 crystal the size of a fingernail. 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 inside, then sighed and shook his head slightly.
"Did you fail?" Kaitian asked.
"Not really, it's barely usable." 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 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 appeared in the image, like a small village, but only a broken wall remained. There are roughly seven or eight houses in the ruins, and civil structures, fired pottery, etc. have appeared. Behind the village is a cave with a cave inside. 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 was 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-finished, 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 would not be able to build such a tall building, or even if they could, it would have to be a structure similar to a pyramid. It would not be such a thin and long pagoda structure, because the material strength would not be as high. , and also lacks knowledge of mechanics and other things.
The last picture is above the altar, and it is also the largest and most colorful one. There are hundreds of little people in the picture, worshiping a plant in the center. The pattern looks like a cactus.
In front of the chief scientist of the research base, four murals extracted from memory were placed, and they were enlarged 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 the research center required that once large-scale civilization ruins were discovered, he must come back and report.
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. His reason told him that this was not true, but his intuition vaguely pointed in another direction.
PS: Happy Christmas Eve!
