Listening to Wei Huang's words.

Looking at the eyes of everyone's expectations.

Qin Yu's eyebrows stretched slowly, slowly: "I probably know all the current situation. I also understand that the severe test that Dawei is about to face is that since the Majesty and the adults trust me so much, I will talk about my thoughts and responses.

Strategy. "

Hearing this.

The humerus in the house was relieved.

They really did not read it wrong.

Wei Huang's dignified face eased a lot, busy saying: "Okay, even if you say, no matter what help and support you need, our old guys are not resigned."

Qin Yu nodded slightly and groaned: "We first consider the problem that is about to occur, and then solve the problem one by one. First of all, the cold winter that may arrive this year, so heating will be the biggest problem facing the people in the north of the northern Weiwei Wei."

"We need to ensure the heating of the people of the Dawei. It is not enough to support the people to spend the winter by relying on charcoal, and the price of charcoal will skyrocket as soon as winter, but if we notify the people in advance, it will easily cause panic.

It is precious, so we need the people to plant the field with peace of mind. "

Listening to the analysis of Qin Yu's glance.

Wei Huang and a crowd of humerus are all exposed.

They knew that Qin Yu would definitely see the blood and analyze the problem.

Even Xiao Nan looked at Qin Yu seriously, and his eyes were full of admiration.

"You are right, you continue to say."

Emperor Wei looked at Qin Yu excitedly.

Qin Yu continued: "In response to the problem of heating, I have four measures to help the people through a comfortable winter."

"One of them is led by the states and counties, allowing the people to build fire at home as the use of warmth in winter."

Fire?

Listen to this fresh word.

Both Wei Huang and a crowd of humerus were aggressive.

Fire?

Fire?

It is quite warm, and that person can’t heal itself?

Dawei was still relatively backward. Fire, coal, stoves and cotton, all these cold things were none.

So the people of this era are really bitter.

Qin Yu got up, took a piece of paper, and pasted it on a wooden frame hanging with a map.

Emperor Wei looked straight and distressed, and the paper was also precious in this era.

Looking at the confusing eyes of everyone.

Qin Yu drew his pen directly on the paper. "Everyone knows the adobe, and most of the people's courtyard and houses of the people today are adobe lids."

"This fire is built with adobe, which is a tablet built with r & Gkin.

He said while painting, "You see, this is a stove built in the outer house, and then this is a flue. The above layer is a bluestone slab, and then the adobe.

It's a chimney. ""

"Put firewood in winter under the stove to burn, you can cook both, but also heat the fire to heat and warm it.

Listening to Qin Yu's words.

Looking at the fire on the drawing.

Both Wei Huang and a crowd of humerus were shocked.

They did not expect that Qin Yu could come up with such a good thing.

"Also, very good!"

Emperor Wei couldn't help but admire, "I know that you have a way, you can study such a good thing such a good fire, these people can be blessed."

"His Majesty Mo is anxious, there are still."

Qin Yu responded lightly, and then drew up again. "We can also let the people build a stove, and the stove can also be used in the house with adobe barriers, but the chimney is also needed. If the smoke is scattered in the house, it will be troublesome."

"Although the adobe stove is inconvenient to move and it is not beautiful, it is enough to protect the cold. This stove can not only warm it, but also use it to cook water and cook."

Fire.

stove.

These two things come out.

The base of Wei Huang and a group of humerus was instantly sufficient.

This is simply a cold artifact.

Because they have been to the warm shed in winter, the temperature inside is very high.

Wei Huang and a group of humerus looked at Qin Yu's eyes, full of admiration.

They know that Qin Yu must have a way.

But they did not expect that Qin Yu came to open his mouth.

If Qin Yu has a good knowledge, they will endure the five cars.

But Qin Yu's cognition completely escaped their vision.

They are all unheard of things and what they have never seen.

Don't wait for them to be amazed.

Qin Yu continued: "With the fire and the stove, we have another problem to solve, that is, the problem of fuel. Of course, wood and charcoal are good things, but the winter is coming, and there are blended prices of rapes, the price of wood and charcoal

Will soar. ""

"It is likely to cause a kind of fire in the home, there are fire stoves, but there is no firewood burning. Then we need to develop a replacement fuel coal, which is the charcoal you said."

Carbon?

Wei Huang nodded with the humerus, and the charcoal was no stranger to them.

Dawei already has awareness of coal.

Wei Huang's brows locked deeply, groaning: "Horse, you know all the truth, but the charcoal is not easy to use. The stuff is smoked as soon as it burn, and it is a poisonous fog, and it will die."

A number of humerus nods echo.

The charcoal can indeed be burned casually.

Qin Yu's complexion explained indifferently: "Of course, ordinary coal should not be burned directly, because ordinary coal contains a large amount of sulfur. If it is directly burned, it will produce sulfur dioxide."

"The sulfur dioxide is very terrible. If inhalation will stimulate the nerve end of the surface layer of the upper respiratory tract mucosa, it will cause the bronchial reflection to shrink and spasm, so ..."

The words did not fall, he reacted, and said, "I ... am I talking about running?"

Wei Emperor: "..."

Xiao Nan: "..."

Qin Wenyao: "........."

7: "..."

The crowd looked at Qin Yu with an aggressive look.

Upper respiratory tract?

Nerve endings?

Bronchy reflex contraction?

They didn't know what Qin Yu said.

Wei Huang carefully: "Press, you ... what upper respiratory tract you just said ..."

Qin Yu waved his hand, "That's not important. You only need to know that ordinary coal cannot be burned directly, otherwise sulfur dioxide will cause damage to the human body."

Wei Huang nodded well, "Well, good."

Qin Yu continued: "Therefore, coal needs to be desulfurized, but this thing is too complicated, and it is difficult to achieve with the current technology, so we need to dig out smoke -free coal, that is, no tobacco carbon."
