Vol 3 Chapter 939: Behind schedule

Returning to the camp, Chu Jungui proceeded to cut two pieces of animal skins that had just been processed. Both goats were hunted, and the cactus branches didn't make any contribution this time. Chu Jungui has 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, they are surrounded by chickens and dogs, and all birds and beasts are far 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, next to the original smelting furnace, a higher and larger smelting furnace has been built. The proportion of charcoal stacked in it far exceeds that of the original smelting furnace. With the addition of a blower, the furnace temperature is bound to increase by one level.
Items in real dreams are generally rich in energy, and the heat released by charcoal is far beyond the real world. The furnace temperature of this new furnace should be above 1500 degrees, which is barely enough for steelmaking in the real world, but here, I am afraid that only ordinary metals can be extracted.
At this time, there was already a small pile of ore beside the new smelting furnace, about dozens of pieces, but it was not iron ore. These ores are selected one by one by Kaitian. There is some copper, but more of them are various rare elements.
Chu Jungui put these ore into the furnace and ignited it. When the temperature of the furnace rose to more than 1000 degrees, he began to manually control the blower to supply air, and then stared at the fire to judge the temperature. Kaitian assists in temperature control by the side. 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 could only see the outer flame, but there were several 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 acquiring data several times in this way, Kaitian's smelting furnace model becomes quite accurate, with an error of no more than 3 degrees.
When the temperature is low, Chu Jungui blows the air harder, and when the temperature is high, he blows more slowly.
In this way, relying on the original means of seeing with eyes and the 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 harvest was almost finished, Chu Jungui continued to raise the furnace temperature, gradually rising to 1500 degrees. At this time, a large amount of non-metallic materials began to melt and flow out, and the main body was silicon. When all of this was finished, Chu Jungui began to add more force to blow the air, and the flames from the furnace mouth sprayed out several meters. Under this brutal and rough pressure, the furnace temperature gradually rose to 1700 degrees!
This time, a small group of molten liquid flowed out, and after condensing, it had a dark silver light.
Chu Jungui breathed out a sigh of heat and put his hand away. This is the case with this original furnace, which cannot meet higher requirements. However, his real gain was not that small group of titanium-based alloys, but the left in the furnace, some of the rare elements with high melting point were all in the slag.
Finally, the furnace was cleaned, and Chu Jungui recovered a mass of about 5 kilograms of slag. Chu Jungui cracked and crushed the slag, then observed the particles, first using the spectral field of view, then switched to the field of magnetic field, and finally judged that the particles contained a lot of rhenium, niobium, tantalum and tungsten. The content of these elements in the unexpectedly exceeds 20%, if in the real world, it is 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 veins have been found yet.
The purification of each of these elements is a question of a university, but Chu Jungui's demand for purity is not so high, and the demand is not large.
The second smelting furnace consumes much more work than the first specialized iron smelting furnace, but it is actually used this time, and the local metallurgy is basically over at this stage. If you want to separate and purify these rare metals with high melting point, you can't rely on this kind of furnace.
But since the amount is not large, Chu Jun has his own way.
He finely grinds the into powder, then spreads it on a polished iron plate and sealed with a layer of wax, and waved to open the sky.
Kaitian sighed and covered it, and saw the particles float up and enter Kaitian's body, and then there were continuous fine powders falling, and the particles became smaller and smaller, until they became invisible to the naked eye.
With the phagocytic ability of the Kaitian cell level, the impurities attached to the surface of the metal particles will eventually be gnawed down, turned into waste and thrown away, and finally high-purity metal particles will be left behind.
One hour later, a thick layer of gray-white powder appeared under Kaitian. Chu Jungui dumped the powder directly, and then a piece of metal particles was sprinkled on Kaitian. Most of these particles exist in the size of hundreds of molecules, and can basically be used directly.
Chu Jungui had turned the refined copper into three thin copper plates, and then gave Kaitian a design drawing.
Kaitian swallowed a bite of rare metal powder, and then wrapped a whole copper plate. The copper plate that Jun Jun made was not big, it was 3030cm in size, and its thickness was about one millimeter.
After Kaitian wrapped the copper plate, the whole 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 2 hours to open the genius before finally spitting out a 2020 metal mesh. The grid is very fine, the whole body is dark yellow, and it is actually a copper alloy mixed with rare elements.
Chu Jungui was very satisfied, put the copper mesh into a special small furnace, connected an electrode at one end, and then set the 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 finished." Chu Jungui put down the electrodes with satisfaction.
The direct conversion of heat energy into electrical energy is a basic operation for humans. Everyone knows the principle, but there are no processing conditions in the real dream. However, 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 processing the parts by himself, preparing to turn that small prototype 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 weak, it has more possibilities with electricity.
The night passed in a blink of an eye.
There was a small smelting furnace in front of Chu Jungui, which 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 in the furnace exceeds 2500 degrees.
The result of the first batch is now in the hands of Jun Chu. It is an irregular red crystal, like a gem. Chu Jungui was polishing this crystal the size of a crystal fingernail. Although he only had an original file in his hand, the processing accuracy was not 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 it fail?" Kaitian asked.
"Don't count, it can barely be used." Chu Jungui raised his head and looked 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 Kaitian, and said, "Try charging."
Kaitian transformed into a human form again, and placed this crystal on the right eye. Then, the core of the crystal was lit up, and a thin hot beam shot out, instantly piercing a piece of iron plate.
At this moment, there was another small commotion in the Federal Moonlight Unicorn Base. The reason was that an explorer voluntarily returned and brought back multiple materials with the specially strengthened memory area.
He is lying halfway in the medical cabin, countless data is being transmitted from the neural interface to the main brain, and then cast a clear image on the big screen.
A ruin appeared in the video, like a small village, but only a piece of broken wall remained. There are roughly seven or eight houses in the ruins, and civil structures and pottery have already appeared. Behind the village is a cave with a different cave. At the end is a hall, and at the end is an altar, on which several weathered beast skeletons are placed.
There are many murals on the cave wall, one of which depicts several humanoid creatures, with one person pointing to the sky in the center, and a complex pattern composed of dots and lines where he is pointing.
This pattern is very abstract, but when it falls into the eyes of many scientists in the research center, it arouses an exclaim.
"This is a molecular structure diagram! Quickly compare and see what substance it is!"
"The matching has no result, it is a brand new structure map!"
"Let’s experiment right away and edit atomically according to the structure diagram to see what can be made!"
The next few murals have similar styles. The second picture shows that people have made weapons similar to spears and shields and are fighting wild beasts.
The third mural shows people building houses and sculptures.
The third picture is that people are trying to build a tall tower, only half of it was built, but according to the ratio of the figure, it is already dozens of times the height of the humanoid creatures. Under normal circumstances, primitive humans cannot build such a tall building, or even if it is built, it must be similar to a pyramid structure. It cannot be such a slender and long pagoda structure because the strength of the material cannot be increased. , And lack of knowledge of mechanics.
The last picture is above the altar, and it is also the largest and most colorful. In the picture, hundreds of little people ~EbookFREE.me~ are facing a plant in the center and worshipping. 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 magnified dozens of times, giving a sense of magnificence and vastness. The reason why the explorer used a precious opportunity to return was because the research center required that once a large-scale civilization relic was discovered, he would return and report it.
At this time, an assistant came over and said: "We have successfully edited the substance based on the molecular diagram. It is an alloy and the composition is... The characteristic is that the density is slightly lower than that of 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 high tower."
The assistant's voice subconsciously softened, and said, "Could these people really exist?"
The chief scientist frowned, and his reason told him that this was not true, but his intuition faintly pointed in another direction.
PS: Happy Christmas Eve!
