Zhang Jun said: "A square table with three chairs, a round table with six chairs or eight stools, and I can create two beds for use. Tables and chairs... two sets of square tables and three sets of round tables, try to be faster."

“Round table with chairs or stools?”

"Two sets of matching chairs and one set of matching stools."

The carpenter took the order and left. These were folk carpenters. After they were built, they had to settle the settlement with them. They would not be in vain.

Zhang Jun and Zhang Liang entered the wooden house.

Because it was cold and it was used temporarily, and there was no window left in the room. It felt like a square tent was nailed with wooden boards, and there was nothing inside, just a big empty room.

The camp was trying to make the floor, and when you were sleeping, you would lay hay on the floor.

The house is made of new wood nails from the newly cut trees. Because the floor is sleeping, it uses old materials that are dry and penetrated through the camp.

Because there are no windows, the room is very dark, which is a bit like a confinement room. The brazier on the ground in the middle releases heat and brings some light to the room, allowing people to see things clearly.

Zhang Jun instantly had a question in his heart: On the day he just woke up, how did he see things clearly in the tent? It felt like it wasn't so dark.

You can't ask, either.

Everyone had seen Zhang Jun and Zhang Liang one after another, and they just gave in. At this moment, except for the lower houses, the idea of ​​superiority and inferiority is not that strong, and their personality is relatively equal.

Zhang Jun looked around and said, "It's better to go out and say it, the room is too dark." He turned around and walked out again. The main reason was that he couldn't stand the smoke from the burning charcoal in the room. After a while, his throat felt a little uncomfortable.

Everyone followed him to the outside again, and it was still the dead branch, still doodle on the snow.

"This furnace can be made of cast iron, two feet and three inches tall, two partitions inside, two holes in the upper size, and two holes in the lower part. Carboniferous holes are thrown into the fire, and the embers are shoveled out from the lower part after burning."

Zhang Jun explained to the blacksmiths while drawing.

There were stoves in this era, and there were many types of stoves for heating, so blacksmiths were not unfamiliar with this thing, but the only way to make it. This was to add a chimney.

"Use thin iron as a cylinder to guide charcoal smoke to the outdoors. The poison of carbohydrate is caused by smoke. As long as the smoke is discharged, there is no problem. All that remains is heat, not only for heating, but also for cooking."

"My husband is serious?"

"Of course. I'm going to come over to build an iron furnace to keep these houses warm. I won't say anything. I'll ask more craftsmen to start work quickly. It's important to complete it within three days, and the army will return to the camp in three days."

"Mr., I'm afraid it's a little tighter in three days."

"The furnace body is cast in a mud mold, and the furnace barrel is thin and soft. It should be possible to recruit more craftsmen. Hurry up and find someone to come. This furnace is only suitable for a while, and there is no need to pay attention to simplicity, just use it."

"Mr. Lang, can this furnace... only be made of iron?" Zhang Liang asked.

"It's not that good, it's just that it's much faster with iron, and it can be moved and placed. If it's summer, it can be replaced by bricks and stones, but the only thing is that it's not moving."

“Is it easy to manufacture?”

"It's not difficult, and it doesn't require strength. Just have hands and feet, and children can do it. But now it's cold and there's no way to build it. I'll teach you how to do it when the weather gets warm."

"If there is really such a simple saying as a husband, the husband will be like a Buddha in all families. Great goodness."

Zhang Jun was stunned and immediately realized that in this era, it was a real big problem for civilians to keep warm. Every winter, the bones of cold and hungry can be seen everywhere. This damn era without cotton.

But the weather is so cold, there is really no way to do it.

The method Zhang Jun mentioned is actually to ride a kang. A hot kang with earth stove is naturally the best way to resist the severe cold, with low cost and quick results.

In fact, the kang has been around for a long time and has been available for a long time.

During the time when Jizi moved east, there was a land nest (now the ground kang of Koreans), and later a firewall was developed. Su Wu had survived the land nest after shepherding the sheep for 19 years.

The Hukang spread from the northeast along the northern border of the Tang Dynasty to the northwest as the Huyi tribe migrated.

However, at this time, the kangs, including the ground nests, fire walls, etc. were used more by the Hu people (they were colder than the north), and they did not enter the mainstream life circle of the Tang Dynasty.

Even now wearing fur is still the Hu people's patent, and most Tang Shi would resist and look down on those who wear marten.

The mainstream Tang Dynasty is now sleeping on the floor (tatami), burning braziers (charcoal), drinking, and stuffing cotton and hemp into clothes.

The main reason is climate problems. It turns out that the Tang Dynasty was not cold. Who knew that it would start to get colder later (700 years later). The heavy snow in Luoyang was more than one foot deep. In the south, I was surprised that the quilt and pillow were cold, and I saw the windows brightly. I knew the snow was heavy late at night, and I heard the sound of broken bamboos at times.

All the bamboos in Jiangzhou (Jiujiang) were crushed by snow.

This climate is like the time of the Tang Dynasty. The first rain may be bright and bright, and then it will change from the Wuzhou period to the cold and become out of control.

As the situation in the Tang Dynasty became more and more turbulent, the winter came earlier and colder every year.

In fact, no matter whether it is warm or cold, it is not a problem for wealthy families. Only the people will suffer. The nobles can raise a group of dancers to warm up the body, and they can use maids to warm their hands. How can civilians have this condition?

Zhang Jun felt that the words "God's will" were not like saying nonsense.

With the change of climate, cotton began to flow in. At this moment, the Western Regions (Central Asia) is the coldest, and cotton-woven clothes have appeared there and are slowly coming in.

This was the first major cooling in the Southern Song Dynasty, and cotton fabrics were already very mature. By the Little Glacier Period of the Ming Dynasty, cotton fabrics had replaced silk, that is, cotton.

Cotton growing in tropical and subtropical desert grasslands that grow in high temperatures, droughts, short sunshines turned out to be a must for the survival of the cold northern humans, and it appeared just right. Could it be just a coincidence?

The coldness of the Tang Dynasty at this time was for the early Tang Dynasty. Compared with the Song and Ming dynasties, it can be said to be warm now.

It is obvious that if the modern climate is set to zero degrees, then in the early Tang Dynasty it would be ten degrees above zero, then twelve degrees, which would start to decline from the middle period, and then to Zhang Jun's current appearance of six or seven degrees above zero.

The Southern Song Dynasty was about minus twenty degrees, and it continued to fluctuate until the middle of the Qing Dynasty, and then began to rise slowly again. That's right, the temperature in the Southern Song Dynasty had a sharp drop, and it suddenly dropped from zero to minus twenty-five.

In the Southern Song Dynasty, the Han Dynasty fell. There was no China after Yashan.

Since history, the highest point of climate temperature was during the Zhenguan period and the Jutang period. The lowest point of climate temperature was during the fall of the Southern Song Dynasty. What exactly happened to be true? Is it a coincidence?

...

"Mr. Lang, can we try to cast one first and observe it before making the process?"

"Yes, what do you need to find the garbankan, the faster the better."

A group of blacksmiths molded the sketches on the ground with hemp paper and went to discuss it. Zhang Jun and Zhang Liang walked side by side on the playground.

"Most of what we are going to face will be the struggle between the envoys. Whether we are willing or not, we cannot change the occurrence of this. In this regard, there are too many things we are not waiting for.

As the saying goes, if you want to do a good job, you must first sharpen your tools.

We have only now gained our foothold, and we have been in charge of all the commanders on our side for more than ten years. Whether it is the soldiers or the government, we are not as good as the ones.
