The drawings drawn on the ground are relatively simple, and it is easy to understand.

"Why do you have two jugs here?" With more than 20 years of experience, Zhao Gong didn't have much problem seeing this picture, but he didn't understand why Chen Ping put two jugs in this place.

Could it be to prevent water from going away? But if that's the case, bring a bucket of water and put it next to the stove.

These two jugs should not take up much space, and they can't hold too much water.

It's weird.

"Naturally, the jugs are used to put water." Chen Ping said with a smile, "My family is different from other households, and they are used to using hot water, but it is not very convenient to boil water often. If you put two jugs on the stove and make a fire to cook, the water from the well can be boiled by the fire. ”

It's all about convenience, it's that simple.

After Chen Ping said this, Zhao Gong took a closer look and thought for a moment.

"Okay, no problem." It is to leave two gaps, modify it slightly, and install the jug, without much difficulty, Zhao Gong raised his head, "Then start now?" ”

"That's the best." Chen Ping nodded.

Repairing the stove is not a big job, but the bits and pieces of the stove next to the stove in the hall still have to be picked up and made some space.

went to call Chen Erniu to come over, Chen Ping took a few people to move the things in the hall to the courtyard, leaving places on both sides of the east and west, and walking the fire road.

"Where is the yellow mud here? Go get some. After vacating the place, Zhao Gong asked the two apprentices to move the green bricks in, and asked Chen Ping.

At this time, the buildings mostly use rammed earth, make a mold, and more manpower can be piled up little by little, even the Daxing City, which is also a rammed earth structure, occasionally add some wooden piles as a support to get up, not to mention local buildings.

The masonry structure is also mostly used in the tomb, and the amount is not much, and some of the tombs are also surrounded by rammed earth, and the tomb is raised on the flat ground, which is indeed shabby enough.

There are three reasons for this.

First, it is inconvenient to take materials for bricks and stones, and it takes a long time, and you make the emperor wait for five or six years? Then you don't have to do it as an overseer, and come in with someone else. Rammed earth structures can save time very much, it is nothing more than a problem of people, is the emperor short of people? Of course there will be no shortage.

The Daxing City of the Sui Dynasty was built in only nine months to build the palace city and the imperial city, although the minister subcontracted responsibility system was adopted, but this speed was really amazing.

As for the Renshou Palace, which was built in the thirteenth year of the emperor, it took a little longer, and it took nearly two years, and Yang Su was the supervisor.

The superintendent is in a hurry, the author dies a lot, and the sound of ghosts crying is heard on the side of the palace. This is recorded in the history books. The use of human life can pile up the progress of the project, although Yang Jian is a lot of idle people, but Yang Su is still rewarded later.

This is very illustrative, even the emperor at the top is so fond of rammed earth structures, so anxious to have a place to live, a place to play. Do you still dare to adopt a masonry structure?

It's really that brick and stone structure, and when this project is built, I'm afraid that half of the emperor's body will go into the earth.

This is one of the timeliness, and the other is the level of the craftsman. It is undeniable that the level of craftsmen at this time is not low. For example, Yu Wenkai, who participated in the construction of Daxing City, Gao Ying is the chief of the main affairs, and Yu Wenkai is the deputy supervisor, a bit similar to later generations, the main position is to lead the overall situation, but the specific affairs are handled by the deputy below. He also participated in the construction of Renshou Palace, at this time he was already able to pick up the beams and be the supervisor of Renshou Palace, and even the matter of the mausoleum of the Empress Wenwenkai, Yu Wenkai also participated.

After Yang Jian's death, Yang Guang ascended the throne, and Yu Wenkai's craftsmanship was given room to display. Luoyang, the eastern capital, the Great Wall, the big tent when Yang Guang was on tour, and the temple of the wind and so on, these are all big deals.

It is a pity that most of them are rammed earth structures, which can be related to masonry materials, I am afraid that it is the mausoleum of the queen of literature, but coincidentally, the Sui Tomb is mostly raised from the ground, and the slope tomb road and brick road are used, although it is a square brick tomb, the requirements for the level of craftsmen in masonry are not large.

There is also the last point, that is, the thoughts of the people of the time pay more attention to the five elements of yin and yang, the earth represents the center, carries all things, and the wood symbolizes life. This taste for the emperor is not only the emperor, but also the ordinary people.

To sum up, these three points are the issues of timeliness and materials, technology, and faith.

But the house can be made of rammed earth, and some things still have to be made of masonry. Just like the stove in the hall of Chen Ping's house in front of him, it has to use green bricks.

"There is one in the east of the village, I'll get it." Using loess as a binder, a bit of soil, but Chen Ping knew that it could be used, and the stove room in the courtyard of his hometown in later generations used yellow clay, which was cheap and saved thousands of cement money.

After borrowing Zhao Gong's ox cart and carrying a shovel, Chen Ping led Xiao Anzi and a few people to the east of the village to get some yellow clay, and then sent it to the courtyard.

Lifting water and mud, taking the iron pot and an application tool on the old stove, Zhao Gong and two apprentices dismantled the old stove, and although the green bricks were black, they were clear but still usable.

Chen Pingyuan thought about whether he should draw a sample and let Zhao Gong do it, but before he raised his head, Zhao Gong's face turned cold, and the two apprentices also had bad eyes, and the three of them were almost leaving.

"Fortunately, it's also a stove, and if it's other work that requires a lot of quantity, it's really a hidden danger." Chen Ping said something bad and apologized, and only then did he leave three people behind, but the taste in his heart was not very good.

The three of them, with the help of Chen Ping and others, when the sun turned west, the stove was also made, next to the wall of the hall in the north, and two fire channels extended from the stove pond to the east and west along the root of the wall.

The surface is covered with a layer of mud, flat and square, and it's okay.

"That's all for today, and I'll come back tomorrow." Zhao Gong packed up a pair of tools, put it on the ox cart, said hello to Chen Ping, and drove the ox cart away.

The face was still a little cold, and it seemed that Chen Ping's proposal was still in mind.

The temper of the craftsman is really big.

"Shouldn't you get a cement out and let him worship it?" The cement formula is not difficult, but the difficult thing is the calcination conditions, Uncle Blacksmith's smelting furnace is okay, and it happens that there is also iron slag, Chen Ping thought.

As for lime, this thing should be there at this time, Chen Ping has the impression that he has seen a certain ancient medical technique, there is a Chinese medicine, and it is mixed with lime. With lime and some glutinous rice juice, it can also be made into soil cement.

But to use food in this way, Chen Ping estimated that it was still too extravagant, and the lime was not so easy to obtain.

"Wait and see, the yellow mud with water is barely feasible now." After precipitating in his mind, Chen Ping felt that it was better not to be too anxious and to be steady.

ordered a big iron pot and two iron cans from Chen Hecai, and Chen Ping went home to help Liu's cook on the fire.

Not to mention, the fire that has just started is fast. Originally, Chen Ping wanted to leave a layer under the stove pond and put a few iron bars on it, so that the burned grass and wood ashes could fall, but this point made Zhao Gong refuse.

"What are you doing here? How did it come to this? As soon as the meal here was ready, Chen Xiaoyi came back with an iron shovel, saw the few green bricks left in the yard, and the new stove in the hall, asked, and looked at Chen Ping, "Are you the ghost?" ”
