Qin Yu's brows relaxed and he said slowly: "I have probably fully understood the current situation, and I also understand the severe test that the Wei Dynasty is about to face. Since Your Majesty and all of you trust me so much, I will tell you my thoughts and how to deal with it.
policy.”
Hear this.
Emperor Wei and everyone in the room couldn't help but heave a sigh of relief.
They were indeed right, the Prince Consort really had a solution.
Emperor Wei's solemn face softened a lot, and he hurriedly said: "Okay, just say it, no matter what help and support you need, we old guys are obligated to do so."
Qin Yu nodded slightly and said thoughtfully: "Let's consider the upcoming problems first, and then solve them one by one. The first is the cold winter that may come this year, so heating will be the biggest problem faced by the people in the northern part of the Wei Dynasty."
"We need to ensure the heating of the people of the Wei Dynasty. Charcoal alone is not enough to support the people through the winter, and the price of charcoal will skyrocket when winter comes. However, if we notify the people in advance, it will easily cause panic. This year's food will be extremely difficult for the Wei Dynasty.
It is very precious, so we need people to farm with peace of mind."
Listening to Qin Yu's serious analysis.
Emperor Wei and all the humerus all looked happy.
They knew that Qin Yu would hit the nail on the head and analyze the problem clearly.
Even Xiao Nan looked at Qin Yu seriously, his eyes full of admiration.
"You're right, keep talking."
Emperor Wei looked at Qin Yu excitedly.
Qin Yu continued: "As for the heating problem, I have four measures to help the people spend a comfortable winter."
“One is led by various state and county governments, allowing people to build fire pits at home for people to keep warm in winter.”
Fire kang?
Listen to this new word.
Emperor Wei and all the humerians all looked confused.
Fire kang?
A burning kang?
It's quite warm. Shouldn't that person be cremated on the spot?
This era of the Wei Dynasty was still relatively backward. There were no fire pits, coal, stoves, or cotton, these things to keep out the cold.
Therefore, the people of this era are indeed living a very hard life.
Qin Yu stood up, took a piece of paper, and pasted it on a wooden stand with a map hanging on it.
Emperor Wei looked at it and expressed his heartache. Paper is also very precious in this era.
Looking at the confused eyes of everyone.
Qin Yu directly took a pen and drew on the paper, "Everyone knows about adobe. Nowadays, most of the courtyard walls and houses of common people are made of adobe."
"This fire pit is made of adobe. It is a platform built of adobe that can be used for sleeping, with straw mats and quilts on top, and a flue below."
He was talking and drawing at the same time, "Look, this is the stove built in the outhouse, and then this is the flue. The top layer is bluestone slabs, then adobe, and the top layer can be laid with a layer of blue bricks. The one next to the wall
It’s the chimney.”
"In winter, burning firewood under the stove can not only cook, but also heat the kang for warmth. It kills two birds with one stone and can help the people keep out the cold."
Listen to Qin Yu's words.
Looking at the fire bed on the drawing.
Emperor Wei and everyone in the group were shocked.
They didn't expect that Qin Yu could come up with such a good thing.
"Also, very good!"
Emperor Wei couldn't help but exclaimed in admiration, "I knew you had a way. You could even research something as good as a fire kang. These people are very lucky."
"Your Majesty, don't worry, there is more."
Qin Yu responded calmly, and then started to draw again, "We can also let the people build stoves. The stoves can also be built with adobe inside the house, but a chimney is also needed. If the smoke spreads inside the house, it will be troublesome."
"Although the adobe stove is inconvenient to move and not beautiful, it is enough to keep out the cold. This stove can not only keep warm, but can also be used to boil water for cooking."
Fire kang.
stove.
As soon as these two things come out.
The confidence of Emperor Wei and the others was sufficient in an instant.
This is simply a magical weapon to keep out the cold.
Because they had been to the greenhouse in winter, the temperature inside was very high.
Emperor Wei and everyone looked at Qin Yu with eyes full of admiration.
They knew that Qin Yu must have a way.
But they really didn't expect that Qin Yu would do this just by opening his mouth.
If Qin Yu was knowledgeable and knowledgeable, they would all tolerate it.
But Qin Yu's understanding was completely beyond their horizons.
They are all things they have never heard of or seen.
Don't wait for them to be amazed.
Qin Yu continued: "Now that we have the fire kang and the stove, we still have one problem to solve, and that is the fuel problem. Wood and charcoal are certainly good things, but with the coming of winter, and unscrupulous merchants are meddling in them, the price of wood and charcoal will
will soar."
"Then it is very likely that people will have fire pits and stoves in their homes, but no firewood to burn. Then we need to develop an alternative fuel, coal, which is what you call charcoal."
Carboniferous?
Emperor Wei and all the humerus nodded, Shi Tan and the others were no strangers.
Dawei already had knowledge of coal.
Emperor Wei frowned deeply and said in deep thought: "Consort, I understand what you are saying, but charcoal is not something that can be used easily. It emits smoke when burned, and it is poisonous mist, which can kill people."
All the humerus nodded in agreement.
It is true that charcoal cannot be burned casually. If someone dies, the gain outweighs the loss.
Qin Yu explained calmly: "Of course ordinary coal cannot be burned directly, because ordinary coal contains a large amount of sulfur. If it is burned directly, sulfur dioxide will be produced."
"Sulfur dioxide is very scary. If inhaled, it will stimulate the nerve endings on the surface of the upper respiratory tract mucosa, which will cause reflex contraction and spasm of the bronchus, so..."
Before he finished speaking, he reacted and said blankly: "I...did I go off topic?"
Emperor Wei: "..."
Xiao Nan: "..."
Qin Wenyao: "......"
7: "..."
Everyone looked at Qin Yu in confusion.
Upper respiratory tract?
Nerve endings?
Reflexive bronchial contraction?
They had no idea what Qin Yu was talking about.
Emperor Wei said cautiously: "Son-in-law, you... what you just mentioned about the upper respiratory tract..."
Qin Yu waved his hand, "That's not important. You just need to know that ordinary coal cannot be burned directly, otherwise it will produce sulfur dioxide and cause harm to the human body."
Emperor Wei nodded obediently, "Hey, okay."
Qin Yu continued: "So, coal needs to be desulfurized, but this thing is too complicated and difficult to achieve with current technology, so we need to dig anthracite coal, which is anthracite coal."
"Although anthracite has lower heat when burned, its advantage is that it has high carbon content and contains fewer impurities. As long as there is a chimney, it is very safe."
