Ren Xiaoyao looked at the six people outside the door, frowned slightly, and remembered Zhang Miaoyu this morning, without thinking that it was her "ventilating message", and asked Huang Xiaoxiao, who was in the lead, "Is there something wrong?" If it's about natural dwellings, I'm going to see you tomorrow. He didn't plan to meet with the people in the natural residence yet, but he didn't expect the other party to find it himself.

"Eh" Huang Xiaoxiao heard the sound of the door opening, and just wanted to speak, but Ren Xiaoyao took the first step to speak, listening to his words, it felt as if there was something going on now. He said, "Okay," and as soon as he said a good word, he felt a breeze blowing on his face, and then the sound of the door closing sounded in his ears.

The six people outside the door, you look at me and I look at you, and they all feel that Ren Xiaoyao seems to have changed into another person, not as kind as before, and feels very indifferent.

Ren Yao in the house heard the footsteps of leaving, and the golden light disappeared in the front yard of the house in a flash, returning to the space. In fact, Ren Xiaoyao doesn't care about the natural residence at all now, it's just that because he only has a verbal agreement with the natural residence, he has lost a simple boiled fish recipe. Anyway, the service attitude and procedures of the natural residence are not up to par at all, even if they give the recipe for the complete boiled fish, they will not use it.

Back to the space, Ren Xiaoyao came directly to the bank of the river, glanced at the house with no doors and windows, looked down at the wooden planks on the ground, scratched the back of his head, the problem came, he didn't know how to make the door, and there was no plywood, how could he make the doors of the earth, and the windows, how to get light without glass, and he didn't want to use paper windows, which felt incompatible with the house.

The door is better, the big deal is to use a few wooden planks to stagger and stack, nail it with iron nails, flatten the edges of the protruding plank, and carve some patterns. Or directly use iron to make the door panel, but it is easy to rust, in this backward era, but there is no such thing as paint. If you go out and shout, where is the paint sold, don't think about it, it will definitely attract the strange eyes of countless people.

Windows are more troublesome, I don't want to use paper windows made of wood and paper, but I don't know how to do it without aluminum, stainless steel, glass and other materials.

Ren Yao stared blankly at the wood in front of him, thinking about the development history of stainless steel, aluminum alloy, and glass, to see if he could figure out anything from it, not to make it, but at least to figure out its material properties, such as why stainless steel does not rust and so on

The term "stainless steel" does not simply refer to one type of stainless steel, but to more than a hundred industrial stainless steels, each developed with good performance in its specific application area. Stainless steel is often divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel and precipitation hardening stainless steel according to the microstructure. In addition, it can be divided into chromium stainless steel, chromium-nickel stainless steel and chromium-manganese-nitrogen stainless steel according to the composition.

Stainless steel is mainly composed of iron, nickel, chromium elements, and because of the model difference, there are other small amounts of small elements. And the 304 universal model, which is 18/8 stainless steel. The standard composition is 18% chromium plus 8% nickel. It is the most suitable for attention, because the products made by this model are: corrosion-resistant containers, tableware, furniture, railings, and medical equipment.

Whether it is in the material or the application field, it can be satisfied, and only iron, nickel, and chromium elements can be manufactured. Thinking of this, Ren Xiaoyao was extremely annoyed, thinking of the nickel absorbed by the universal knife before, he really wanted to cry without tears, but fortunately, there were other meteorites that could be refined.

Chromium, on the other hand, is a bit more troublesome, and is mainly extracted from chromite, ferrochrome spinel or aluminochrome. Chromite is the only mineable chrome ore with a complex mineral composition, variable magnesium content, and sometimes aluminium and iron. There are about 30 kinds of chromium-containing minerals in nature, but only chromite has industrial value.

Therefore, as long as Ren Xiaoyao finds chromite, he can refine stainless steel, not only can he have the iron he wants, but also has the chromium element, and the ability to reuse space, it is completely possible to refine stainless steel.

Aluminum alloys have one to nine series, nine classifications. The first series belongs to the series with the most aluminum content, and the purity can reach more than 99.00%, and does not contain other technical elements. The second series of aluminum plates is characterized by high hardness, among which the copper element content is the highest, about 3-5%, which is not often used in conventional industries, and belongs to aviation aluminum.

The third series is composed of manganese as the main component. The content is between 1.0-1.5, which is a series with good anti-rust function. The four series belong to the series with high silicon content. Usually the silicon content is between 4.5-6.0%. It belongs to building materials, forging materials for mechanical parts, and welding materials; Low melting point and good corrosion resistance.

The five series belongs to the more commonly used alloy aluminum plate series, the main element is magnesium, and the magnesium content is between 3-5%. It can also be called aluminum-magnesium alloy. The six series is the most optimistic about Ren Xiaoyao, mainly containing magnesium and silicon, which are suitable for applications with high requirements for anti-corrosion and oxidation. It has good usability, easy coating, and good processability.

Six series of 6063 aluminum alloy is widely used in the frame of building aluminum doors and windows and curtain walls, in order to ensure that doors and windows and curtain walls have high wind pressure resistance, assembly performance, corrosion resistance and decorative performance. Its chemical composition consists of silicon: 0.20-0.6 iron: 0.35 copper: 0.10 manganese: 0.10 magnesium: 0.45-0.9 chromium: 0.10 zinc: 0.10 titanium: 0.10 aluminum: balance.

The seven series mainly contain zinc and also belong to the aviation series. Most of the applications of the eight series are aluminum foil. The nine-series aluminum alloy is a backup alloy.

Thinking of this, Ren Xiaoyao's brain was stunned for a moment, and the whole person was stunned, and said to himself: "This, how do I know this?" Isn't this the expertise that the guy from Goldway has concocted? After speaking, I remembered the scene of more than ten years of high school on Earth.

Gao Dewei was a chemistry expert in high school in Ren Xiaoyao's previous life, and he liked to find all kinds of materials to experiment, and at that time, because the Internet was not so developed, there was no encyclopedia, so he found a lot of materials and studied all kinds of strange things.

Because Ren is free but very loner, and his personality is also very eccentric. The two met in a school chemistry competition, and over time, they smelled the same, and both of them had strange personalities and became good friends. In the next high school period, whether the two of them explored chemistry knowledge, Ren Xiaoyao also learned a lot from it, but after so many years, I didn't expect to remember.

He didn't know that at the same time when he became the host of space, space was all the "storage" of his body, in addition to obvious blood changes, there were also memories in the brain, whether it was the memories of the past life or the present life, all copied in space like a computer, which caused his memory to be very amazing, and he could remember the memories of more than ten years ago. It can be said that except for the things of infancy, he can remember them as long as he thinks about them.

Ren Xiaoyao came back to his senses, stretched out his hands, looked at the palms that were no different, and there were still ten fingers, and said to himself: "Am I still a human?" At this moment, he thought that such a change in himself must have a lot to do with space.

However, only a silent breath echoed him.

Looking up at the house standing in mid-air, he sighed, he didn't know what he would evolve into with such a change, and in the end, would he become a creature that did not belong to human beings like an alien in the earth's science fiction movies, and he would not even be able to create a human being at that time, which would be a tragedy.

He glanced down at the wooden board on the ground, stunned, and countless Chinese characters, English, and pictures flashed in his mind, all of which were the words and knowledge he had seen, all presented in his mind, and he had not forgotten it at all. If he wants to learn the words of Sunset Country now, he will definitely not forget it. He didn't know what caused this, but it was his instinct.

came back to his senses and said to himself: "Forget it, if it's not a human, it's not a human, and I don't know if I can go back to the earth, so be it." After speaking, a white light flashed in his right hand, and a prosaic-looking knife appeared.

Ren Xiaoyao took a knife and cut it at the camphor wood on the ground, and made a few simple doors; Three very simple door locks were made of iron, so simple that there was no keyhole. And on the wooden door was decorated and carved some of the usual patterns on the ordinary doors of the earth. However, when I look at the preliminarily formed wooden door, I always feel that it is not good-looking, because the wooden door has not been dyed, but the original color of the wood - light yellow.

I remembered the last time I sold ginseng, I bought saffron, and as soon as the middle finger of my right hand flashed white, a small sack appeared in my hand. When I opened the sack, I saw a small, dark "branch".

Ren Xiaoyao glanced at the red "branch" in his hand, turned around and removed the iron lock of the door, and immediately sent a message to the space, asking him to make a virtual large water tank come out in mid-air, fill it with water and boil, put the wooden door in, and add saffron to make the door stain.

Saffron is not only a valuable Chinese medicine and a luxury spice, but also used for food flavoring and coloring, and as a dye. That's why Ren Xiaoyao cared so much about saffron before he was free, and he always felt that saffron abortion was too wasteful.

I saw a flash of white light in the space, a brown light fell from the sky, fell in the middle of the river, forming a huge virtual water tank, a river on the river surface flew away from the river, to the virtual water tank, and after the water tank was filled with water, a red light appeared in the sky shrouded in the water tank, and at the same time the wooden door on the bank flew into the water tank autonomously.

Seeing this, Ren Xiaoyao immediately poured all the saffron in his hand into the water tank, and then immediately made more than a dozen wooden aluminum alloy window-like wooden windows, because he didn't think of the doors and windows at the beginning, so the ones he kept were aluminum window-type windows, so Ren Xiaoyao had to make zuò wooden materials to make zuò hand-pushed wooden windows, although the wood can't be lighted, but just open the windows

I don't know how long it has been, but I saw Ren Xiaoyao staring at the house on the river with full attention, breathing a sigh of relief, and said to himself: "It's okay, just make aluminum windows to replace the wooden windows when the time comes." ”

I saw that the windows and doorways of the houses on the river, which were originally vacant, had been installed with pale red wooden windows and doors, and the doors were better and looked nothing. But if this window were to be seen by the earth, it would definitely laugh down, because the wooden window looked like an aluminium window, it was all sliding, but the whole window was made of wooden blocks, which was incompatible with the house.

Ren Xiaoyao also looked at the pale red window door, shook his head, and was very helpless, not that he was lazy, but he really didn't know when he made the aluminum window, although he now has a lot of chemical information in his head, but he has no raw materials.

Glancing at the strange modern reinforced concrete house, he flashed out of the space. The house as a whole has been completed, and the space can be brought out, as long as the time comes to make a little furniture or something, you can live in it

When Ren Xiaoyao came out, it was already dusk, and it was almost dark, which meant that he had been in the space for at least ten hours, and according to the time difference of 30 times the space, he had not rested or slept for 300 hours or more than 12 days.

Shrugging his shoulders and stretching his waist, Ren Xiaoyao looked at the house behind him, and said to himself: "It seems that I am really not a human anymore, and I can't feel tired for so long."

After speaking, he walked straight to the house, passed through the hall, came to the backyard, and looked at a few trees more than one meter high, and the whole tree was covered with small burrs like needles, a golden light flashed between Ren Xiaoyao's eyebrows, and a shovel appeared in his hand.

Seeing the white light of the shovel flashing, he flew away from Ren Yao's hand on his own, and went to a few trees full of small burrs like pinpricks, and dug one such tree into a tree to be transplanted in three strokes, and dug out the entire tree head, separating the tree head from the soil.

Ren Xiaoyao looked at the goldenbark tree that had been separated by the shovel, and a golden light flashed between his eyebrows and all disappeared, leaving only a few large tree pits. Ren Xiaoyao knew the poison of this golden bark tree, although he felt that he was not a human, but he still did not dare to underestimate the poisonous animals and plants, his life was long, and he didn't want to risk his life.

The moment the Golden Bark Tree was collected into the space, Ren Xiaoyao sent a message to the space, asking him to envelop the Golden Bark Tree and not let any creatures get close, but it was this order, and Ren Xiaoyao didn't remember that there was such a tree for a long time, and this tree also brought him a surprise.

Put away the golden bark tree, Ren Xiaoyao looked up at the sky, it was not completely dark, and he was going to go out to buy some things and come back, and get the house out of the space, otherwise with the height of the house, the three or four meters high wall could not block the sight of pedestrians on the street, if you do it at this point in time, you may be better seen by your eyesight, then you won't be fooled by yourself.

However, he didn't know how to hide the house, if he wanted to get it out of the space, wouldn't it be seen by other people, it was hard to say, it was given to me by God, I had a dream, and then it appeared. Unless he builds the wall high, but that can't be because of the air circulation
