Qian Yu actually wondered about this problem for a long time, he originally thought that the opposite side was a barren mountain, and there was no living water, which was not suitable for human habitation at all, but when he was cooking with the ram, he found that there was a well next to the kitchen, and the water in it was sweet and pure, so in his heart, this place had long been upgraded to a feng shui treasure with mountains and water.

Yes, in Qian Yu's opinion, barren mountains are also mountains! Marble, which is as white as jade, and blue as water, is definitely the best building material, and it will be put in the future generations, and you will make a fortune just by selling stones. And the Flying Dragon Gang has people and materials, even if they are short of money, it's okay to build a single-story brick house on their own, right?

Yue Fei sighed: "It's not that I don't want to build it, but no one will!" There are only stones and clay here, and it is okay to build a courtyard wall, but it is not possible to build a house. The clay wall is not strong at all, and it can only be covered with thatch, and there is no problem at all if it does not rain, and when it rains, it is all kinds of leaks and all kinds of collapse. Isn't building a house just to shelter from the elements? The house we worked so hard to build up, the wind still blows, the rain is drenched, what are we tossing it for? ”

"Can't cover it?" Qian Yu's eyes were full of disbelief: "Can't you learn?" When someone else builds a house, let's find someone to watch from the sidelines, and we can learn it after a month, right? ”

At this time, even Han Niu looked at Qian Yu with an idiot's eyes: "Building a house is a secret of people's brick kiln villages, asking them to build a house, even the main family can only avoid it, how to learn?" ”

Qian Yu was really speechless, even such a flamboyant thing as building a house could be kept secret, and I don't know how these people did it.

"If we want the Wyvern Gang to develop, we must have our own place. I think it's better to build a house now, anyway, it's enough to charge one or two people for the stall fee, I know a little bit of knowledge about building a house, we can discuss it together. ”

Qian Yu said this selfishly, when he saw the Hesui brothers and sisters trembling in the leaky room, he vowed to help them build a comfortable brick house, the best house in Yunxi Village is the rest room with a wood-based structure next to Yanjing, but such a house does not satisfy Qian Yu. So he wanted to test the water here first, otherwise he would have no silver in his pocket, and it would be useless to have no materials and a builder.

"Do you know how to build a house?" Yue Fei was really stunned at this time, he thought that Qian Yu was very smart and witty, could cook, and knew poetry, but now he even knows how to build a house, is this guy a jack of all trades?

Qian Yu was a little embarrassed: "I just know a little theoretical knowledge, except for helping my dad build a pigsty, I have never practiced." ”

All......

Although he didn't make a move, Qian Yu was still somewhat sure. When he built a house in his hometown, he laid his hands on the side, from the foundation to the top to the tile, the whole process was known, and the house in his hometown was a two-story building, and he was only ready to get one floor, which was a lot less steps, and the certainty of success was much greater.

So he called the ram and monkey who lived in the Chu River and Han Realm to kill, and pulled the big bear over, how to lay the foundation, how to build the wall, how to make a triangular beam...... I talked about everything in detail, and I patiently answered everything I didn't understand, and when he finished speaking, an hour had passed.

The ram slapped his thigh regretfully: "I said how the house collapsed just after seeing a little rain, it turned out that the foundation not only had to go deep, but also had to be smashed, we used to find a vacant lot and go to the base, and it was already very good to be able to hold on until it rained." ”

The monkey nodded: "Oh, to make a big beam, you have to nail the rafters into triangles first, not simply put them head-to-head, I see." ”

Han Niu stared at the sky for a long time: "Tie a stone with cotton thread and hang it down so that the wall will not be crooked." When I was a child, I saw people in the brick kiln village doing this when I climbed a tree to dig out birds' eggs, and I didn't care about it at the time, otherwise the firewood house I built would not have collapsed first. ”

After Qian Yu listened to the discussion of the three of them, the cold sweat on his forehead broke out. Big brother, did you build a house so casually before? I dare to live in such a house, and I am really lucky to be able to live until now!

Yue Fei looked at Qian Yu and hesitated a little: "Ke Oil, in fact, I have thought about these problems, although the solution is not as good as yours, it is no problem to build a house that can live in people." But the biggest problem now is bricks and lime, without these two things, you can only use clay and stone to make up the numbers, and the things that come out still don't last long! ”

Qian Yu coughed lightly: "Brother Yue, don't worry, the little brother hasn't finished talking yet!" Let me focus on the detailed firing method of building materials such as green bricks, tiles, and lime! ”

Yue Fei......

Qian Yu ignored Yue Fei's embarrassed face: "In fact, the key to success or failure of something like this that needs to be fired at high temperature is the uniformity and heating of the material, as long as the material is fully mixed and the heating balance is ensured, it will basically be successful."

The main material of green bricks is clay, and the required temperature is not high, so it is relatively simple. Tile...... Well, the tiles need to be glazed, the technical content is too high, and it is not very useful, give up first.

Lime is not difficult, but we want to be able to burn cement, but the cement process is too complicated, in addition to clay and limestone, but also to use iron ore, etc., try it first, not then use lime instead of ......"

Another hour passed, and Qian Yu was surprised to find that a simple house, wanting to build such a complicated process, China's thousands of years of architectural history is really broad and profound.

When he saw that the brothers of the Flying Dragon Gang looked confused from beginning to end, it was estimated that the principle theory training course of this hour was in vain.

Qian Yu had no choice but to use a wooden stick to depict the firing method of green bricks, lime and cement on the ground in the form of a flow chart, he only said the steps, not the principle, so that Yue Fei nodded with some understanding.

After speaking, Qian Yu took out all the silver in his arms, took out one or two for backup, and handed the rest to Yue Fei: "Big brother, although most of the materials are available on the mountain, you always have to buy some more, plus tools and food for your brothers, you can't do it without money." I can't use this money for the time being, so I'll stay in the gang for now! ”

Yue Fei hurriedly shirked: "No, this is all your savings, keep it for your future daughter-in-law." Take it out now, are you ready to be like a ram and fight a bachelor for the rest of your life? ”

Qian Yu said helplessly: "Don't hide it from my eldest brother, I am also selfish, when the house here is built, I want to ask the brothers to help build a house for Hesui in Yunxi Village!" ”

Yue Fei nodded understandingly: "Is that the girl who is eye-to-eye with you in Sanlipo?" No problem, your business is everyone's business, and the house will be big and bright! ”

Several other people were immediately full of interest in this gossip, and after listening to Yue Fei's details, their eyes were full of ambiguity, including the simple-minded Big Bear. Qian Yu no longer wants to deal with this group of lewd men.

*******

Yue Fei led Han Niu to dig clay, ram to chop firewood, and Qian Yu and the monkey went to the market to buy tools. When everyone gathered again, Qian Yu commanded Daxiong and Hanniu to build brick kilns, and discussed making bellows with the ram.

The brick kiln is easy to say, as long as the outside is solid, the inside is made into a narrow cylindrical shape, and then there are enough vents and observation openings, he briefly talked about it, and the two of them have understood. It was the bellows, and Qian Yu was surprised to find that the use of bellows by people in this world was extremely low, and there was only a simple hand-pulled type.

How's that going to work? Qian Yu, who was accustomed to modern electric blowers, showed strong dissatisfaction and decisively improved this technology, so a wooden enlarged version of the electric blower was born, except that the shaft of the fan was connected to an additional crank, and the operation method was similar to the old-fashioned hand-cranked noodle machine.

Then there is the molding, if you want to fully mix and compact the clay, you need a mixer and a press, the mixer is made, but after adding the clay and water, even the most powerful bear can not turn, or the ram recommends increasing the proportion of water, mixing the mud through the flow of water, and then pouring the mud into a fixed mold, pressing out the water with a heavy stone, this inspiration is the ram from the method of making tofu.

The wisdom of the working people is indeed infinite, and Qian Yu found that although he had nearly a thousand years of knowledge more than them, this did not mean that he was necessarily better than them. Of course, when everyone saw that Qian Yu only used a few pulleys, he easily lifted the thousand catties of boulders representing the stamping machine, and they were even more shocked and speechless.

After everything was ready, the bricks were formed in the sweat of the brothers of the Flying Dragon Gang, and the bricks made by Qian Yu were four times larger than those of later generations. This can't be helped, although Qian Yu tries his best to make the whole process more labor-saving, he still can't escape the role of manpower in it, and increasing the volume of bricks is the most direct way to improve efficiency.

When the bricks are fully dried, they are carefully moved into the brick kiln, arranged neatly in a horizontal and vertical manner, and leave enough spacing, and then seal the kiln, add firewood, and ignite, six hand-cranked bellows are placed in the air inlet to be shaken, and the flames with a blazing red light spew out along the vents, and the thick black smoke goes straight to the sky.

Looking at the sporadic falling carbon black, Qian Yu's heart twitched, this is the rhythm of PM2.5 increase, fortunately, there is only one brick kiln, if you build it again in the future, you must find a deserted place!

Qian Yu didn't know the specific time when a kiln brick was burned, he could only judge by feeling by observing the holes, and make detailed records.

Of course, he was not idle, except for leaving two people to watch the fire, and the rest began to build lime kilns.

Compared with the brick kiln, the lime kiln is simpler, there is a confined space, which is convenient for heating, and the raw material used for burning lime is white marble, no embryo is needed, it only takes one day and one night, and the snow-white lime powder is piled up in the courtyard.

Looking at the curling mist rising from the water put into the lime block, Yue Fei and the others couldn't stop laughing, they never expected that the lime firing method, which was regarded as an exclusive secret technique by the brick kiln village, would be so simple, they looked at Qian Yu with admiration and admiration in their eyes.

Qian Yu was not in a good mood, when they burned lime in the big bear, he also added the cement formula in his memory, maybe the firing time was insufficient, and the product came out except for the slightly gray color, there was no stickiness at all.

What Qian Yu didn't expect was that the success of the lime made the enthusiasm of Han Niu and others increase exponentially, especially Da Xiong, although he could move stones the size of a grinding disc before, but it was limited to lifting, but now he moved from morning to afternoon, without effort!

It wasn't until Qian Yu watched the rooster exchange the burned lime for a basket of bronze coins that he knew that this thing was in short supply.

He also finally understood that the ancients' application of lime not only to build bricks and brush walls, but also to sterilize and remove insects, which is equivalent to the current 84 disinfectant.

Four days later, the bricks of the brick kiln also completely changed color, and Qian Yu let the ram burn for a day before the fire was extinguished, and after the temperature dropped to normal temperature, the kiln was opened!
