At this time, all the shopkeepers of the blacksmiths in Four Seasons County were overjoyed and confused. A teenager riding a horse collected all the waste residue in the bellows of the blacksmith and iron-making and made a lot of money, but the shopkeeper of the blacksmith didn't understand why the teenager wanted the slag, and after thinking about it, he agreed that the teenager was a fool.

At this time, Ren Xiaoyao rode back to Nanshi on horseback, and rode to the house he had just bought from Zhang Miaoyu, and the fool in the minds of the blacksmiths was Ren Xiaoyao, who just now swept away the waste slag in all the ironmaking bellows in all the blacksmiths in Four Seasons County. Because Ren Xiaoyao is equipped with cement, there is a slag missing.

The ironmaking method of this sunset country is block ironmaking, that is, at a lower smelting temperature, iron ore is reduced to a solid state to obtain sponge iron, and then forged into iron. Then after casting into a embryo, casting is first heated into molten iron, and then condensed into shape, after forging into various utensils, forging is the so-called iron.

Because if you make iron, you can't reach the melting point with charcoal, so when you make iron, you use coal in the Sunset Country. And because of this backward iron-making method, Ren Xiaoyao can get the slag needed in the configuration of natural cement, and the waste slag in the furnace in the ironshop can also be called blast furnace slag, but compared with the blast furnace slag of the earth, one is high-grade and the other is low-level.

Blast furnace slag is a kind of waste slag that is discharged from the blast furnace when smelting pig iron. When smelting pig iron in a blast furnace, the raw materials added from the blast furnace are added to the furnace in addition to iron ore and coal, as well as fluxing materials. When the furnace temperature reaches 1400-1600 °C, the fluxing material reacts with iron ore at high temperature to form pig iron and slag. Blast furnace slag is composed of gangue, ash, flux and other impurities that cannot enter the pig iron, and is a fusible mixture, which is the slag required for the configuration of natural cement

Ren Xiaoyao rode a horse to a big house by the city wall in Nanshi, got off the horse and glanced at the house number, took out a key from his arms, and pulled the horse straight to the house. When I came to the big red and black wooden door, I saw that the lock on the door was very thin and looked like it could be broken with my hands.

Unlocking, pushing the heavy wooden door, there was a squeaky rotation sound, Ren Xiaoyao looked up at the door shaft of the wooden door, and said to himself: "This door has also been changed, and I don't know what fell down." With that, he pulled his horse and went inside the door and locked it.

At the moment when Ren Yao locked the door, most of the pedestrians on the street whispered to the house, many people knew the "strange things" of this house, it can be said that this house has become very famous in this street, almost everyone knows that the people who live in this house, dead and sick, full of all kinds of strange things.

They all knew the people in the house, but they had never seen Ren Xiaoyao, and it was a little strange for a stranger to suddenly walk into the house, and a thought came to their hearts: Could it be that this house has changed hands? Didn't he know that the feng shui of this house was bad? In fact, they all thought right, the house has changed hands, but the house has nothing to do with feng shui.

Ren Xiaoyao entered the house, locked the door, and even people and horses flashed into the space.

When I entered the space and came to the yard, I felt that there was no one in the yard, and I didn't know where the little sister and the woman had gone to play. Ren Xiaoyao looked up, and there were more than a dozen piles of gray-white ashes in the middle of the space, with a little lump in the powder, and immediately sent a message to the space, asking it to gather all the ashes together and grind them into powder.

I saw a white light flash in the space, and a black light appeared, forming a false tornado, gathering more than a dozen piles of gray-white ashes in mid-air together, and a royal blue strong light flashed in the tornado from time to time.

Ren Xiaoyao looked at the tornado in mid-air, and said to himself, "What is this?" Why is it different every time? "It's a bit frustrating that the space doesn't follow the routine. Seeing that the tornado's original black appearance gradually turned into a gray-black appearance, it immediately flashed to the bank of the small river in the space, and at the same time sent a message to the space to bring the tornado with it.

Coming to the bank of the river, Ren Xiaoyao took out a large amount of lime and clay, used the ability of the space, and soared in the air, and then sent a message to the space to mix the cement according to the proportion of the cement last time, and he took out a large number of stone bricks of different colors and a large number of marbles from the storage ring.

I saw that the space was empty again, and various colors of light appeared, and the mixing tools were virtualized, and the lime, clay, and slag were arranged into a pile of natural cement powder in proportion, and the extradition river water flowed backwards to the cement powder in mid-air, and began to mix the cement.

Ren Xiaoyao saw that the cement was already stirring, so he hurriedly took out the river sand and sent a message to the space, asking him to add the river sand to the cement slurry and stir it in the ratio of one part cement slurry to three parts of the river sand. This time it was just a wall, and there was no need to add small stones. And let all the stone bricks that have just been taken out of the shore be thrown into the river. And Ren Xiaoyao commanded the universal knife to cut the marble.

The stone bricks are thrown into the water because there are many fine voids inside the stone bricks, which have a certain amount of water absorption. If you don't soak in water or don't soak enough water to build the wall directly, the stone bricks will absorb the moisture of the cement, so that the connecting part of the stone bricks and the cement will appear voids, and the bond will not be firm, resulting in hollowing, tile falling off and other problems.

Since it is said to "soak in water", the stone bricks must be immersed in water, and a large basin will be prepared for the construction party on the earth. However, there are also some irresponsible construction teams, stacking the tiles and pouring water on them with a water hose, so that the tiles can only be soaked, and the tiles can not be fully "drunk", and various problems are likely to occur after paving.

Since different tiles have different water absorption, there is no specific standard. But the end result is that the tiles will "drink to their heart's content" until they no longer bubble.

If the water absorption rate is high, it will be soaked for a longer time. During the rainy season, the air is humid and the time is shortened. When the weather is dry in the hot summer, the time increases accordingly.

After a while, Ren Xiaoyao cut all the marble blocks into lying stones of the same size, and also used his spatial ability to throw the marble blocks into the river, and a large number of bubbles came out of the river, and I don't know if it was caused by the stone bricks or the marble blocks absorbing the river water.

Ren Xiaoyao glanced at the river, came back to his senses, looked at the house frame on the river, suddenly his eyes widened, and he said to himself: "I almost forgot about the pocket and the stairs." After speaking, he looked at a small number of marble fragments and clay on the ground, and immediately was confused, just now he only remembered to use marble to make porcelain tiles, and forgot to leave a piece of marble for squatting.

Suddenly, a peculiar idea came to my mind, to melt all the marble rubble, cool it down into a squatting urinal, and do it when I think about it. A message was sent to the space, asking him to melt all the marble fragments on the ground into magma and make a squatting toilet.

I saw another pale green light in the space to lift the fine marble gravel on the ground into the air, and a dazzling white strong light shone on the marble, and in an instant, I heard the bass sound of the marble being heated. Some of the tiny stones have burned white and are slowly turning red.

Ren Xiaoyao took a slight look at the fragments in the air, and remembered the nature of clay: in the process of heating and calcining, after the clay reaches a certain temperature, when the temperature continues to rise, the eutectic material in the clay begins to melt, and the liquid phase appears and gradually increases, filling between the solid particles, due to the action of the surface tension of the liquid phase, the unmelted particles are further brought closer, causing a sharp shrinkage of the volume, a decrease in porosity, and an increase in density.

Thinking that even if the marble was melted into a squatting toilet, there would still be small stone holes, and he didn't know how to block the stone holes, which was already a natural phenomenon of stones, and it took a lot of chemical knowledge to solve it. If the marble is melted, there are too many small stone holes, and there are human fertilizers left

It's disgusting to think about it, but the nature of the clay is just right to minimize the stone holes in the stone, so that at least it can reduce the residue of human fertilizer on the squatting toilet. Looking down at the clay, he sent a message to the space to add the clay to the marble magma.

However, the reaction of the space made Ren Xiaoyao stunned, because the space did not react at all after receiving Ren Xiaoyao's news, the clay on the ground on the shore was not less at all, and the red magma in mid-air did not have any clay components.

Ren Xiaoyao sent the information to the space again, and seeing that the space had not reacted, he looked at the sky blankly and said to himself: "The space is too busy?" Why is there still no response. Turning his head to look at the cement stirred in the air, he suddenly realized, because it was the first time to use space to do such a thing, and there was no detailed transmission of information, like proportion or something, of course the space did not react.

Immediately, another message was sent to the space: the magma and clay were stirred and melted 10:1. I saw that a pale green light immediately shrouded the clay pile in the space, and a large pile of clay rose up, flying towards the red marble magma. The moment the clay entered the magma, a large amount of white gas came out, and after a while, an illusory silver-white thing similar to an egg beater appeared in the sky above the magma, and it spun on the magma rapidly, and the clay disappeared into the magma, and the color of the clay could no longer be seen.

Ren Xiaoyao took a look at the molten slurry, then looked back at the river surface and cement, and saw that the cement had been stirred, and there were no bubbles on the river surface, so he immediately used the space capacity to build a wall.

I saw that the wooden planks and brackets on the room frame all disappeared with a flash of golden light in the space. A large number of stone bricks "fly" out of the river and fly towards the already built house frames; The cement in mid-air, as if it had life, flew towards the stone bricks on its own and stuck to the surface of the stone bricks. The stone bricks, which had been stained with cement, flew to the frame in a regular manner, and stood heavily on the frame.

Ren Xiaoyao is now distracted, staring at the stone bricks flying towards the house frame wholeheartedly, for fear that if he is not careful, there will be hidden dangers. Slowly, the first floor of the house frame has been built according to the plan in Ren Xiaoyao's mind, and all the walls have been built. Then the second floor, then the roof.

Just as Ren Xiaoyao was engrossed in building the wall, I don't know when two women appeared on the shore, one big and one big. The younger girl was holding a small sky-blue animal that looked like a fox in her arms, while the slightly older woman stared at Ren Xiaoyao with a ghostly look
