Because many people suffered from carbon monoxide poisoning after using coal in winter, they began to think that it was toxic, and even ordinary people did not dare to use it easily.
Every winter, many people freeze to death because they cannot afford cotton clothes.
The idea that coal is poisonous is deeply ingrained in people's minds. Even if you tell them that there is no danger in using it properly, those powerful and wealthy people will definitely sneer at you.
Ordinary people had a very difficult life and were reluctant to spend money to buy coal.
If they could afford it, they might as well spend it on buying clothes or making quilts.
Therefore, coal has never been widely promoted.
The coal-burning kang was specially designed by Yiye, and the chimney was outside, which could extract all the carbon monoxide from incomplete combustion.
It can ensure absolute safety, allowing people to spend the winter warmly without having to worry about being cold.
As people feel the benefits of kang, coal will gradually be accepted.
Princess Ruyue was still shocked: "This thing is poisonous and cannot be used!
Someone had burned coal for heating before, and ended up with the whole family dying.
Later, too many problems occurred and no one dared to use it. "
"Yes! No one dares to use this thing!" Zhao Wudi also hurriedly spoke out to stop it.
Of course, Ye knew what they were thinking and said with a smile, "Coal is not poisonous in itself. It's just that it can't burn fully in a sealed room, which results in the production of carbon monoxide, which actually suffocates people to death.
The kang I designed can completely isolate the smoke from burning coal and discharge it through the chimney.
People cannot come into contact with it at all, so naturally they will not be poisoned.
Let me tell you, this thing is great for keeping warm in winter.
And after being made into coke, it burns even hotter, making it very suitable for forging iron.
It was this method that I told Moyefang that allowed them to create such a fine weapon."
After hearing this, everyone looked at each other and looked at Ye in disbelief.
I really don't understand how Ye knew how to use coal.
Besides, I've never seen him use it before.
"Don't just stand there, it's absolutely right to listen to me, would I harm you?
Whether we can survive this winter depends on the amount of coal mined.
It must be put on the agenda as soon as possible.
If we mine more and gather them together, it will be more convenient to use in the winter."
Suddenly, Ye had a new idea.
Now that we have coal, we can build some greenhouses to grow vegetables in winter.
It’s just that this generation has no plastic sheeting, but glass has come out.
In order to make huge profits, Ye has been controlling the production of glass, and the purity is not that good.
But if you want to grow greenhouse vegetables, you can consider expanding glass production.
You can eat fresh vegetables even in winter.
"I'll give you a bigger surprise in winter! We need to mine more coal." Ye said with a smile.
Everyone looked at each other, and they were even more confused.
"What's so mysterious about this surprise?"
"I can't tell you now, it would be meaningless if I told you!"
"Okay then. We'll take note of this and ask you again in the winter."
Although Princess Ruyue was very curious, she did not continue to ask since Ye did not say anything.
The next thing to do every day is to train the army and inspect the construction of the village.
The entire border is bustling with activity.
The villages are connected to each other, forming a Great Wall.
Although it was only built about seven meters high, the enemy could easily climb up.
However, if the barbarian cavalry loses their warhorses, their combat effectiveness will be greatly reduced.
Ye was confident that he could annihilate all the enemies that climbed over the wall.
This was also a trap left intentionally.
If the enemy came to attack, they had to abandon their horses and climb inside the wall.
But after they crawled in, they were no match for the defenders.
This method can easily destroy the enemy.
Although the barbarians received the first batch of goods, the subsequent trading prices did not drop.
Ye still traded with them at three times the original price.
Even each shipment must specify a sufficient number of cattle.
It is not easy to refuse if the proportion is too small.
This made the barbarians very angry.
Cattle are difficult to raise and are an important farming tool in Dayuan.
Sheep are just food and can only be eaten as meat.
They didn't want Dayuan to get too many cattle.
But the amount of goods that Ye supplied them could not meet their needs.
Prices in the barbarian tribes began to rise rapidly.
The barbarian king could no longer bear it and angrily summoned all the generals and officials to discuss countermeasures.
"Dayuan treated us like fat sheep, not only increasing the price of goods by three times, but also reducing the quantity they provided.
This is definitely intentional on their part, they want to drag us down!"
As soon as this was said, the pro-war officials immediately stood up and said, "Your Majesty, we can't wait any longer! We herdsmen don't have many cattle and sheep.
All of them were exchanged for salt, tea and other supplies, but by the time winter comes, there may not be enough food.
Many tribes will not have enough food to eat, and may even starve to death in the winter.
It would be better to raise an army immediately, launch a surprise attack on Dayuan, and capture their city.
Let the people of Dayuan know the price of offending us!"
"Calm down, don't be so impulsive! The more this happens, the more you have to hold back.
Our troops have not arrived yet, and the lost troops have not been replaced.
Starting a war now is exactly what Dayuan is planning."
"I also think we shouldn't go to war. I don't know what Dayuan is up to. We can exchange the wool we don't want for money.
In that case, why not collect more wool and sell it to them.
This can save a lot of sheep.
After all, it’s not too bad! "
Some people were calmer and stopped those who wanted to retaliate.
The barbarian king frowned and said, “What do they want the wool for? We should send someone to find out.
I don’t think it’s that simple, and I can’t be fooled by them.”
"Okay, I'll arrange for someone to investigate!"
"I think it won't do any harm to us, so there's no need to be so nervous, right?
Especially during the molting period in spring and autumn, the grass is scattered everywhere, making it inconvenient for the animals to graze.
Picking them up and giving them money in exchange is also good for us!"
“That’s true, but we can’t let them take too much advantage.
Although wool can be exchanged for money, the price is too cheap."
After discussing it for a long time, they still couldn't come to a conclusion.
They also don't want to fight Dayuan right away.
Instead, we need to buy time.
The most troublesome thing is that the allies cannot get enough supplies.
Often quarrel with each other.
If it weren't for the fact that Wu Yu was in control of the barbarians, they would have turned against him long ago.
They were all holding back their energy, ready to equip their armies as soon as they got the weapons.
Look for opportunities to invade Dayuan.
In the following days, large quantities of wool were sent to Dayuan.
Some people even pluck the wool from the sheep.
It will grow back anyway, so there won't be any damage.
Saving a sheep is a profit.
This was a good deal for Ye, as he could purchase large quantities of wool at super low prices and produce a large amount of wool yarn.
