After Lu Zhe announced that he would help the whole village make a fire kang, everyone was enthusiastic, and they took out various tools from home one after another, waiting for Lu Zhe's arrangement.

Unexpectedly, Lu Zhe did not immediately let everyone dig the mud, but called the housewives of each family and Liu Chang, the mason, to their own halls, and told them the general appearance of the kang on the spot, and then took Liu Chang to visit each family in turn, and counted the size and size of the kang that each family needed.

The clay kang is very simple to say, it is generally built around the wall, first use soil or masonry to enclose a rectangle on the side of the wall, and there are several rows of low walls as flues, and then cover the board on it, seal it with mud, make a hole on one side of the frame, connect it with the stove, and then on the other side, usually dig a hole in the wall to take the smoke, this hole is generally connected to the chimney.

But in ancient times, when productivity was low, the biggest problem was the board covered on it, and the wooden board was definitely not good, it was necessary to have a thin and flat stone slab, and there was only one stonemason in the mountain village. Within twenty days, it is okay to get together one kang slab, but to get nine kang slabs is a fool's dream.

"If only there were a cutter." Lu Zhe thought hatefully.

However, in the end, this problem was solved, and the reason why Lu Zhe went up the mountain to find red sandstone was to solve this problem.

Because the red sandstone has good cohesiveness, the ground red sandstone is mixed with the soil, covered on the wooden board, and then dried and then covered with a layer of mud to make a wooden core concrete, which is used to replace the stone slab, so that the progress of the project is greatly accelerated.

After synthesizing the opinions of the mason Liu Chang and the public loser Lin Haoshui, the next day, the vigorous mass production movement began.

First of all, Lu Zhe refined the work, first divided the people into groups, according to the labor, divided into dredging group, transportation group, wood-cutting group and food group, each group found a person in charge, Lin Haoshui and Liu Chang had another task, even the children were called to collect the dead grass in the mountains, and then break it and live in the mud to increase the cohesion of the soil.

After the group, the next morning, the whole mountain village began to get busy.

"This wheelbarrow is very useful." Lin Lishui had red eyes, watching his son push dozens of catties of soil, walking like flying, and couldn't help but admire. Lin Wuyi, a half-sized boy, was immediately assigned to the transportation group, pushing the cart back and forth between the river and the open space in the middle of the village.

Lin Lishui's task is the heaviest, he not only has to make wooden planks, but yesterday, Lu Zhe told him the design of the wheelbarrow again, and asked him to make more unicycles, preferably one for each family, after doing it, each family can also have multiple means of transportation.

Sure enough, when he saw the design of the wheelbarrow, the ecstatic Lin Lishui patted his chest and promised that there was no problem, he did it for a day and a night, and finally made three wheelbarrows early the next morning.

"Of course, this is my master's secret." Lu Zhe is also quite proud, this wheelbarrow has a large load capacity, simple production, easy to push, and I don't know how much effort is saved compared to shoulder-to-shoulder. And the control is convenient, ordinary people can get started as long as they learn a little, and the ditches and bumps on one side are directly pushed over.

During the War of Liberation, the common people transported materials to the front line, using this kind of wheelbarrow, and defeated the eight million national army with millet and rifles, creating a miracle.

At this time, the open space in the middle of the village had become a large construction site, and a large pit had been dug in the middle of the clearing, and the excavated earth was mixed with the mud by the river, and several women were stepping on the mud vigorously, and people were constantly adding grass stalks to the soil.

In the past, the ancients made things, generally a craftsman was responsible for all the work, and the time was generally longer, Lu Zhe adopted the assembly line model, one person was only responsible for one kind of labor, so that the excavated soil and sandstone were transported, the soil sent was stepped on, and the chopped firewood was cleaned up, which greatly accelerated the progress of the project.

What Lu Zhe didn't expect was that the three brothers of the Shadow Family turned out to be stonemasons, Shadow Crane went out of the mountain to change things, Shadow Heron and Shadow Snake joined the labor, and under Lu Zhe's command, the two brothers spent a day to build two stone mills.

The red sandstone quarried from the mountains is put into a stone mill and ground into red powder.

This is a very laborious and time-consuming work, Lu Zhe didn't expect that the seemingly thin and small shadow snake, as if it had inexhaustible strength, turned the grinding disc for a morning, almost without stopping, Lu Zhe couldn't help but glance at the physical strength of the people in the mountain gate.

And the mason Liu Chang also brought a surprise to Lu Zhe, he told Lu Zhe that the flue inside the kang does not have to be all adobe bricks, after piling stones into a rough shape, filling them with mud, the effect is the same, and he only came back from the mountains A large basket of strange grass, after squeezing out the juice, added to the soil, it is said that it can accelerate the solidification. A kind of grass was also harvested, which was also made into a sap, which was said to prevent the bricks from sticking together when they were burned.

are all talents, Lu Zhe couldn't help but sigh, no, after hearing that a large amount of firewood was needed, Tie San went around the forest, and soon found firewood with excellent burning effect, and he also improved Lu Zhe's earthen kiln for burning bricks.

A master of plastering, a master carpenter, two master stoneware, and a hunter who is proficient in mountain and forest products and kilns, Lu Zhe feels that there is still something in the mountain gate.

Because many things Lu Zhe just described a rough blank, they not only understood it as soon as they heard it, but after the improvement of several of them, Lu Zhe's idea could not only be implemented, but also more practical.

Lu Zhe not only lamented that the wisdom of the ancients was a bit against the sky.

As everyone knows, when he lamented that the wisdom of the ancients was against the sky, several elders in the village were also lamenting that this son was a demon.

"Orderly, there is a law, and these women and children can exert such great strength, and it is even more implied in the art of war, this son can be called a demon." Elder Deng looked at the hot construction site below and was amazed.

"Don't think that this is the ability of this son, first cause everyone to hurt themselves with the tragic situation, and then inspire everyone with slogans, chanting for days, and making it a habit, it seems simple, but in fact it is to twist everyone's heart into a rope, this kind of scheming skills, it really should not be a teenager. Do you still remember 'Da Chuxing, King Chen Sheng'? Elder Ming looked at Lin Wuyi and Duan Ergou while shouting, "A plate of fire kang to drive away the cold", and pushed the wheelbarrow forward like crazy, sighing to himself.

As a person from later generations, Lu Zhe knew the importance of slogans when working collectively, so he imitated the appearance of the people's commune in later generations, intentionally or unintentionally leading everyone to chant slogans when working, at first, only a few teenagers and children thought it was fun to shout, and those women and adults felt that they couldn't let go, but later, everyone found that when they were tired, they suddenly shouted "a plate of fire kang to drive away the cold", thinking of the scene described by Lu Zhe, the tired body seemed to have a lot of strength.

And when working, there are more than one person, everyone can't help laughing, under the noisy shouting, it is extremely lively, diluting a lot of the fatigue caused by repetitive work, under the labor of one ring after another, everyone actually compares with each other, just to say that they have a sentence to the person, "Slow down, I'm done, I'm waiting for you." ”。

"This son, is he really a disciple of the Immortal Family?" Hearing Elder Ming's words, the two of them pondered carefully, and they couldn't help but have the same thought in their hearts.

By the ninth day, Lin Haoshui's planks had been prepared, and all the materials were basically ready, and he could officially start burning bricks.

The previous soil, after mixing, will be put into the wooden mold, the mold is also very simple, is a detachable, boxy wooden frame, pour into the soil and step on it, scrape the surface with a bamboo knife, and then remove the wooden frame, put aside to dry.

The autumn sun is not poisonous, but after a few days, the mud bricks slowly harden. By the ninth day, all the mud bricks had been made, and the first ones had dried and hardened.

The hardened mud bricks were carefully put into the soil pit dug in the center of the village, and the bottom of the soil pit was brushed with a layer of water of unknown plants, which is also said to be the secret of Liu Chang's family, so that the mud bricks and the soil do not stick.

The mud bricks are also brushed with a layer of water to ensure that the mud bricks no longer stick after firing. Then, Tetsuzo carefully put the firewood that had been prepared long ago into the gap between the mud bricks, stuffed it to the ground, and finally lit the fire.

The fire burned for a day and a night, saying this, Lu Zhe had to admire Tie San, he was simply an expert in setting fires, the firewood he put in, he said that it would be burned for a day and a night, it really happened to burn for so long, presumably he also had a special method of burning the fire.

After the fire was extinguished, the pit was filled with a thin layer of soil, and the prepared "wood-core concrete" slabs were placed on it, and then covered with a thick layer of soil, using the embers of the fire to harden the mud planks.

The next morning, after everyone had dug up the earth with hope, everyone shouted hello when they saw the situation inside.

The thick mud planks have hardened, and when you knock it with your hands, it feels no different from the stone, and the bricks below are even stronger, Lu Zhe looked at it, and there was almost no difference from the red bricks of later generations. But they should be larger, one foot long, five inches wide, and three inches thick.

This time, almost 200 bricks and a lot of mud and wood boards were burned, enough for three families to install. According to Elder Ming's inference, there are still ten days to go, and the first snow is about to fall, and according to the progress of one kiln in two days, almost before winter, all families in the village can install ondols.

Looking at this progress, everyone couldn't help cheering, shouting, "A plate of fire kang drives away the cold." The crowd suddenly became a sea of joy.

First of all, the three elders of the village were installed. Because all three of them live alone, they don't need many bricks, and there are even leftovers.

In Elder Ming's hall, the couch inside had long been removed, and instead there were rows of one-foot-high mud walls piled up with pebbles and mud, and a hole had been dug in the back wall, and a chimney made of mud behind the hole had also been dried at this time, and on the other side of the wall, there was also a small earthen stove, which was also made by Liu Chang in the past few days.

Everyone carefully built the adobe bricks into an L-shape, together with the wall, forming a rough frame, and then smeared with mud, proficient in arson, Tiesan, who was also careful and careful to calculate the position of the firewood, put the firewood into the flue, and then, by Liu Chang covered the self-made wooden core concrete slab, the general appearance of the kang was basically formed, and when Liu Chang smoothed the soil on it, sealed it with mud around it, and connected the hole that deliberately flowed out with the bottom of the stove.

After everything was done, Tetsuzo lit the firewood in the kang cave.

"Smoke, smoke." With an exclamation, everyone ran outside the house, and behind Elder Ming's exquisite stone house, there was a very ugly chimney that was constantly steaming. Everyone exclaimed, happy as children.

After everyone touched Elder Ming's kang, everyone's eyes lit up.

"Why is it so hot?" Tie San touched the temperature on the kang at this time, and frowned, at this temperature, wouldn't people have to be roasted.

"Really?" "I want to try it" "I want to try it too" Hearing Tie San's voice, everyone was curious, and regardless of the hot hands, they stretched out their hands one after another, grinning their teeth hot.

"You don't have to worry, at this time, it is because the flue in the kang is to be burned hard, so so much firewood will be used, see that there is no stove next to the kang, after the kang is set up, all the aunts can cook in this stove, and the heat generated is enough for the whole family to need for a day."

"Really, Tetsuwako? This relationship is good, how much less firewood is spent, and your Uncle Duan doesn't have to go up the mountain to collect firewood every day. ”

"Great, this winter, the concubine doesn't have to go outside the house to cook, in the past, when it was winter, it was cold outside the house, and it was not easy to cook."

"Zhewazi, my aunt is going to talk about you, there is such a thing, and now my aunt's family, won't they stay here all winter? Shengsheng has made the family lazy. ”

"I'm afraid it's not like you're messing around on the kang all day long."

After seeing the fire kang, the eyes of the women who were doing the housework every day lit up, saying that this was a good thing, and began to talk about it, and most of the women present were married, and they were not afraid to talk about meat and vegetables, and they were about to go to some strange places.

"Ahem!" Elder Deng coughed heavily, and then these women remembered that they were in Elder Ming's house, so they quickly shut up, and they all looked at the earthen kang in the house, their eyes full of joy.

"Let's all go back, every house will have this thing in a few days, and then we will see enough." Seeing that the elders' faces were a little embarrassed, Lin Jiang hurriedly shouted, and everyone hurriedly dispersed.

The consequence of this situation is that many people have not slept all night, thinking about their own ondol, and come to the construction site with red eyes the next day. However, it did not affect their progress at all, but worked harder.

Under the unprecedented enthusiasm of the people, on the nineteenth day of the project, that is, two days before the snow predicted by Elder Ming, the last family's fire kang was also prepared.
