Take Taobao with you to another world

Just an ordinary person.

At least from Yunshen's own point of view, this is true.Double master's degree, second middle school and first senior engineer position, project team leader of a large state-owned enterprise, and two and a half years of expatriate work experience. Officially resigned within three days and had to rely on the power of the Space-Time Administration.However, there are too many talents in the motherland. There are a 23-year-old Ph.D. who has tackled key technologies of national key scientific research projects and a 26-year-old chief engineer of the aerospace department. It's nothing.After coming here, all the academic qualifications and positions in the past have become clouds. Although the knowledge in his mind is still there, the knowledge system built on the basis of several industrial revolutions can only really play a role in the distant future.As an individual, his survivability is very low, and his physical fitness is not very good. As for powers that are not within common sense, such as spells and arcane arts, they are of course farther away from him.If there is anything commendable about him now, it is his firm will and his luck is really good.

From the point of view of his social Darwinist friend, history is always changed by exceptional geniuses and fools, while the overall progress of society is driven by the elite, and the vast majority of ordinary people are only geniuses and fools. The soil from which elites are born.Ordinary people are providers of social needs and sharers of results. Standing at one end of the watershed are creators and controllers at the other end. No matter how society progresses, this class is almost impossible to disappear.And for him, a dead house mortal who is much more active on the Internet than in reality, a winner in life like Yun Shen, who has entered the elite class early but has no self-consciousness, is really not an ordinary nuisance.

"This sentence has too many loopholes in logic." The winner in life said, unknowingly switched back to his mother tongue, "There is only a combination of images without specific directions. This sentence cannot have a precise interpretation. And the explanation The power is in the hands of the publisher, and it only needs to add or delete supplementary conditions for the facts that have occurred to realize its logical self-consistency..."

Fan Tianlan's eyes have turned into the shape of --.Although he seldom showed any obvious expressions on his facially paralyzed face at a young age, but he got along day and night, taught by precepts and deeds, Yun Shen was quite sensitive to the emotions of this young man who had become half of his student.He smiled a little embarrassedly, and stopped.

"Then that's it." Fan Tianlan said, although in addition, Astaros already knew the origin of Yunshen, the Storm Lord's consistent reputation was reckless, but he rarely intervened in affairs outside the territory. The text messages sent are already very rare and weird.The eye-catching appearance of black hair and black eyes is like a drop of water in a lake among the survivors. Nanshan and Li Hong may also have guessed about Yunshen's origin and identity, but no matter what guesses they have had, it is impossible to confirm that Yunshen is real in this group. In the night of status, Nanshan took the lead in making an oath to him, which already explained their choice.

Yun Shen nodded slightly, "No matter what others say, what we have to do is still the same."

Plans that have already started should continue unless force majeure occurs.

After the summary meeting, Yun Shen focused his energy on the iron-making furnace. After preparing the materials for such a long time, the most core part of all the plans and the most anticipated part of the survivors represented by Li Hong finally started construction.In fact, they have already built a pig iron furnace with self-burning and turning masonry before that, which can produce hundreds of kilograms of pig iron a day, but it needs to go through other processes before it can be turned into wrought iron that can be put into use. As for steel, don’t think about it for now. .No matter how many golden hands were opened, Yun Shen couldn't buy a small blast furnace directly from there. Even if he could buy it and send it over in its entirety, it would not be of much benefit to him and those who were struggling to accumulate construction experience.Therefore, the project still started from the initial stage in a proper manner (according to Yunshen's standard).

Almost all the bricks produced from the brick kilns that had been built and put into use were put into the construction of iron furnaces.The cost of building materials is so staggering, mainly because the walls of the melting furnace and the preheating chamber are quite thick, a full 70 centimeters. Yun Shen does not need to worry about this aspect of the project. The problems that really require his hands are concentrated in two aspects. One is the crucible , and the other is the refractory bricks in the furnace, both of which must be able to withstand high temperatures above 1600° in order to meet the design requirements of Yunshen.At present, the diatomite that Yunshen can master can make silica bricks. The iron ore they are currently mining is of high grade, but it is acidic pyrite. What they need to do is only alkaline furnaces, and silica bricks cannot be used—— Although it is also possible to use it, the service life is relatively short, and the steel quality of the furnace is not very good.Either bauxite, or magnesia bricks are the best.

Judging from the resources at hand, as long as there is enough time, Yun Shen estimates that they can also find dolomite to make magnesia bricks, but right now he is in a hurry, and he can only use more expensive methods to obtain suitable materials .Crucible, by contrast, is a bit of a headache.There are basic materials such as magnesia, clay, and slaked lime, which does not mean that they can burn things out.Everyone like Wu Yunduo also experienced several failures when building the first crucible, and some people were injured because of it. At present, only Yun Shen and Li Hong are one and a quarter technicians, and it is even more difficult. .

But Yun Shen is different from those predecessors who established the country's initial industrial foundation with almost nothing, he has cheats.

With the help of modern instruments and technical theories, Yun Shen and his technical team led by bereaved clansmen only managed to create a suitable crucible after four failures without even an explosion.Modern crucibles can barely be made, but Yun Shen thinks that this pace is too fast - although he has already made a great leap forward so far.In this era of this world, the way to make iron is to overlap coal or charcoal and selected iron ore layer by layer, burn out the molten iron and cast it into pig iron blocks, and then forge and process.The quality of the finished product depends on the craftsmanship of the blacksmith. A skilled blacksmith is valued no less than a mage. This is why although the dwarves occupy the mine veins, few people dare to compete with them.

According to the ratio provided by Yunshen, the members of the technical team put the pig iron, wrought iron, slagging material quicklime and cosolvent fluorite in the sintered crucible, and then put it on the furnace frame built with magnesia bricks , into the refined coke.The fuel is ignited, the bellows blows air into the furnace, and the exhaust gas after combustion enters the No. [-] regenerator controlled by the valve. was blasted into the furnace.

The heat wave rolled out, and people instinctively backed away. Fan Tianlan pulled Yun Shen behind him, squinted his eyes and stared at the blindingly white flames from the smelting furnace.

"It melted," he said.

Li Hong put on his sunglasses and got closer. Looking through the observation hole, the black raw iron in the crucible had turned red, melting at a visible speed just like candles or lard.Yunshen prepared three pairs of glasses, and the members of the technical team gathered here have seen almost all of them. The iron in the crucible has almost melted, and the dark red iron spreads horizontally on the surface of the crucible.

The next job is to speed up the decarburization reaction of the molten iron by stirring. The steel brazing destroys the calmness of the surface of the molten iron, and the white molten iron at the bottom turns up, making it difficult to look directly at it. Wisps of light blue flames rise from it, and the scene of the boiling of the molten iron People gave out complex exclamations, and Li Hong sighed, "It's like magic..."

"It's just a natural phenomenon when it is heated to a certain level." Yun Shen replied.

Stirring brings not only boiling molten iron, but also lumps of slag.Yun Shen asked people to use a special crucible spoon to fish out the slag on the surface, and then poured it into the pool next to it.Someone curiously picked up a piece of black steel slag and knocked it into a pile of dust.

"The role of slag is to take away impurities in molten iron. Only pure iron combined with an appropriate proportion of carbon can be called steel." Yun Shen said.

The second batch of slag-making materials was added to the molten iron. Li Hong fished out a little molten iron and poured a section of iron bars in the pottery groove, and then Yunshen used the sparks generated by the iron bars rubbing on the grinding wheel to judge the degree of molten iron in the smelting furnace. degree of decarbonization.

Several times of slag making, several times of test pieces, in this small brick bungalow, the air baked by the fire made almost everyone sweat all over, Yun Shen was a little better, he was far away from the stove , and there was no need to do anything, but there was some dampness on his forehead, and the hot wind slightly blew his black hair across Fan Tianlan's clean forehead. He stood in front of Yun Shen, but he didn't even break out a drop of sweat.

The first crucible is finally out. The crucible weighing more than 100 kilograms was clamped out of the furnace by several crucible tongs, and the heat in the house rose again.Together with his companions, Li Hong tilted the crucible carefully, and slowly poured molten steel into the molded diatomite soil tank. In order to prevent air from entering the billet, a layer of quicklime was first spread on the surface of the molten steel, followed by charcoal powder.

While waiting for the billet to cool down, Li Hong wiped the sweat off his brow, and looked at Yun Shen with some hesitation.

"Master, what should we do next?"

Yun Shen also hesitated, "Uh, I don't know how to strike iron."

It was the first time to hear Shu Shi say the word "no", but seeing Shu Shi's thinner body against Fan Tianlan, everyone took it for granted.

Li Hong glanced at the black billet again, "Master, I mean... this is steel...?"

"Yes." Yun Shen said.

Is that really enough?Li Hong was taken aback when the sorcerer said that he wanted to make steel directly.In this world, iron is easy to get, but the appearance of a good piece of steel is not as easy as gold.After the era of sharpening gold for the survivors, there are very few blacksmiths who can forge a piece of good steel. Even the dwarves will not export it. The blacksmith of the orcs once told Li Hong that if a blacksmith If he was able to hit steel that weighed more than the weight of a human head, he could live in the imperial capital.He never doubted whether a magician could make steel, but the process he imagined should be more complicated, more difficult, longer, and more... In short, it is not like this, burn it, stir it, and pour it out , I didn't use much strength, and it was over.

Li Hong really wanted to confirm with the magician again, but finally held back.

Two hours later, all five crucibles were released, and the billet cast in the first crucible had completely cooled down.Yun Shen temporarily left because he had other jobs, and the rest of the staff moved the billets to another workshop.There is no thing that can cut that billet, and Li Hong is reluctant to directly use the whole billet to build it—if it is really steel.He picked up the last piece of test piece, put it on the anvil and hit it hard, and the test piece made a clear buzzing sound.

"..."

Li Hong looked at the piece of black metal under his hands, took a deep breath, and put it into the fire.

Several hours later, a dagger was delivered to Yun Shen.Fan Tianlan picked up the gleaming dagger, threw a fist-sized stone into the air, and waved it.The falling stone was evenly divided into two parts, and the steel blade of the dagger did not show any signs of damage.

"It looks okay." Yun Shen said.
