Only by living in peace can we be happy, Qin Song firmly believes in this. A shelter that is warm and safe enough makes it easier for people to feel a sense of attachment and belonging, and it is also easier for serfs to fight to protect their homes.

Mobilizing forces to build infrastructure is the foundation of our foothold.

Ordinary sintered bricks, the raw materials are cheap, and the firing process is simple. Even if Qin Song didn't know what the structure and principle of the high-end brick kiln was, firing ordinary bricks was nothing more than curing the dried clay bricks at high temperature to increase the strength.

Therefore, Qin Song's plan is relatively simple - use the stone at hand in advance, build the first brick kiln, use the coal mines in the Heishi Mountains as fuel, make a large number of brick molds, concentrate all the strength in his hands, fire the first batch of bricks, and then use this batch of bricks as materials to build a larger brick kiln.

No matter how simple brick is, it is much stronger and more practical than wood. In special periods, it is not necessary to deliberately pursue how high-end and durable the bricks are burned, what is needed is a short period of high output.

In order to provide a high enough temperature for the brick kiln, the steam engine can also be put to use, as long as a simple set of blower equipment is designed, with belt drive, the high temperature required for sintering can be achieved.

With bricks, it must be used with cement. Therefore, the cement calcination plant will be carried out simultaneously with the brick factory.

Once the first large-scale brick factory and cement factory are completed, the brick-burning process becomes proficient, the amount of bricks produced is stable, and the cement output is stable, the entire Blackstone Collar will have access to a steady supply of building materials, whether it is to build houses, factories, fortifications, or military fortresses, it will be fully guaranteed.

This idea requires the assistance of many forces. Every power of the Blackstone Collar will be fully utilized.

The location of the brick factory was chosen on the banks of the River Ness, rich in clay. The farmers of the Black Stone Collar are responsible for the first stage of the process, crushing, sifting, mixing, and drying the bricks from the brick molds, as well as collecting limestone for crushing and mixing with clay to make cement slurry.

Qin Song's warriors were responsible for the most important brick sintering and cement calcination procedures. As for Sir Weimar's power, it is to mine open-pit coal in the Blackstone Mountains to provide sufficient fuel.

Not only did Leah need to build a lot of shelter, but Sir Weimar was also eager to change the situation, so the two sides hit it off and said that they were completely obedient to the arrangement.

Time waits for no one, and from the dawn of the next day, all forces are in action. Sir Weimar gathered his 74 serfs and 60 servants, a total of 134 men, and under the leadership of Linda, found an open-pit coal mine in the Blackstone Mountains and went all out to mine it in advance.

Leah, Elena, Karrick, and Eric organized all the farmers and farmers, as well as the newly purchased serfs, and a total of nearly 300 adults and children, to mine and mix the clay.

As for Qin Song, he led the well-trained warriors of No. 80 to carry stones, dismantle the steam engine, and transport it from the canyon to the established location of the brick factory.

Six days later, the first brick kiln designed by Qin Song himself was built, with a vertical structure, resembling a large bell buckled on the ground, with a diameter of about three meters and a height of four and a half meters, with an air duct on the upper part, a combustion chamber and a chimney below, and the outer layer of the furnace in the middle was made of a mixture of stone and clay, and the high-temperature resistant lining was made of two parts of plant ash mixed with one part of clay.

For six days, Alice worked around the clock with iron ingots provided by Lia to make twenty pairs of standard five-grid brick mold frames, as well as a brand new steam No. 2 machine, and a blower No. 1 shaped like a large horn with blades.

I have to say that Alice really has a talent for mechanical design, and under Qin Song's slight touch, this girl has a scattered mind, and uses the knowledge and principle of the circle to manually create two sets of bearings with steel balls, lubricated with animal fat, which perfectly solves the transmission problem of blowers and steam wheels.

At the end of the first week of the month of rotting leaves (11), the first batch of dried bricks was delivered to the brick kiln under the personal escort of Leah.

The first sintered bricks, about to start.

Leah, Alice, Linda, Elena, Luna, Carrick, Eric, as well as Sir Weimar and Caice, as witnesses, arrived at the brick-burning site with curiosity and excitement.

"Luna, is this the machine you said could move itself when boiling water?" Kayce looked at the strange metal machine in front of the brick kiln, he had heard many times from Luna's descriptions of this magical machine, but he couldn't imagine how it worked.

"Yes, Caice. Luna smiled sweetly, "You will see for yourself in a moment, this is the intelligent creation of His Excellency the Wise." ”

"Well, what about the Wise One?" Kayce couldn't help but feel a little nervous as he searched for the figure of the legendary Child of the Stars.

"Your Excellency, you are making the final arrangements. Luna tugged at his sleeve and gently pointed to the makeshift wooden shed not far away.

In the wooden shed, Qin Song was writing and drawing with a quill pen, while Ralph, Hunn and Merlin stood quietly to the side, listening to his detailed instructions. Both of them are relatively short in stature, which is more suitable for drilling into the furnace and stacking bricks. Hunn, on the other hand, was responsible for adding coal to the hearth.

"Have you remembered?" Qin Song raised his head slightly, the light in his eyes jumped, and swept over the faces of the three of them one by one.

"Remember, Commander!"

"Very well, it's up to you to perform. If anything goes wrong, they will all be dismissed and demoted to infantry!" Qin Song's voice was grim.

"Understood!"

In the eyes of everyone, Qin Song, who was wearing a gorgeous robe, lifted the door curtain, walked out with an elegant demeanor and stride.

Among the people at the scene, Weimar, Eric, and Kayce all saw him for the first time, and their expressions were a little nervous, especially the eyes that were jumping with light, coupled with the descriptions of the witches, which naturally carried a kind of majesty.

Qin Song lightly swept over everyone's faces, bowing slightly: "Ralph, Merlin, let's start." ”

"Yes. ”

Ralph and Merlin answered in unison, Ralph took the lead in climbing in through the small arch of the hearth, while Merlin handed him the bricks outside, and according to Qin Song's instructions, he kept a certain gap and stacked them neatly into a stack of bricks.

Qin Song secretly estimated that this simple brick kiln could be filled with more than 300 bricks at a time. According to the estimation of 128 bricks per square meter of the second and fourth walls, it is almost more than two square meters, and the output is indeed limited.

However, the current measuring tools are not accurate, so the design of the bricks is slightly larger in length, width and height than standard bricks.

But it doesn't matter, this brick kiln is just a preliminary verification, so that everyone can understand the principle and procedure steps of firing bricks, and first burn enough bricks, you can redesign and build a larger and more reasonable brick kiln.

After the bricks were filled, Ralph came out of the furnace door and together with Ralph sealed the furnace door with clay and stone. Hunn, on the other hand, filled the hearth with firewood early, and after the sealing was completed, he began to light the fire and add selected fine coals in turn.

"Alice, it's time to start the steam engine. After the coal in the furnace was ignited, under the command of Qin Song, the furnace of the steam engine was also ignited, and with the opening of the gas transmission valve, the heavy runner slowly rotated, and the exhaust valve snorted outward.

The tough cowhide belt drove the blower placed in the air inlet, and began to whine, spinning, and the blowing air flow caused the flame of the furnace to rise all at once.

Everyone held their breath, looking at this magical machine and the bulging brick kiln, and their minds responded to the interlocking procedural steps, and there was a wonderful sense of industrial coordination.

It is better to teach people to fish than to teach them to fish, Qin Song will not tie himself to the brick factory, this place will be handed over to Liya and Weima to manage, and he only needs to give some guidance in the general direction at the right time.

It takes about a day to fire, and the clay particles will melt during firing, and then go through a red-hot state, a yellow-hot state, and a white-hot state, and the bricks will become extremely hard.

Qin Song remembered watching a program on repairing the collapsed section of the Great Wall, which restored the whole process of building the Great Wall and firing Great Wall bricks in the Great Qin Dynasty. In the program, a kind of brick kiln appeared, similar to a tunnel dug under the ground, built into a huge furnace with bricks, a large number of Great Wall bricks were placed on the top of the furnace, closed with clay, and the pumping force of the flue was used to reach a high temperature of 1000 degrees only by using firewood, and the strong and durable Great Wall bricks were fired.

When using this simple brick kiln to burn enough bricks, a larger and more reasonable brick kiln will be built, and the output of bricks will be greatly increased, and then the clay composition ratio and the firing temperature will be controlled to fire better quality bricks.
