Jing Qi is still worried about things in the mining area.

But no matter how worried he was, he could only do nothing.

The weather was too cold and the accommodation was too shabby.

It can be lit, but not too big, and the heat in the house is limited.

The warmth measures are not enough, and I often wake up in the middle of the night from the cold, and then get sick.

As the number of people grows, so does the impact.

Jing Qi, who was distraught, suddenly heard a commotion outside.

"One by one, it's really idle and moldy!" Jing Qi couldn't help but be a little angry, and immediately got up and walked outside the house.

Seeing a group of people twisting a small guy with a small body, there seems to be some blood on his face?

"What happened?" Jing Qi asked with a stern face.

"Chief, this grandson wants to kill us."

"That's it, he doesn't want to die himself, and he still wants to pull us on his back, why ask for someone?"

"Huh?" Jing Qi's brows furrowed, and his eyes couldn't help but look at the little ghost.

"I didn't...... I really don't have ......," the little ghost looked at Jing Qi with a face full of grievances.

'Smack......'

A heavy slap hit the back of the ghost's head, making a dull and crisp sound.

"Dare you say no? How old is that house? Can it withstand your toss? I see that you just want to collapse the house, bury it in me, and even save digging a pit, your conscience is really broken, phew, shameless......"

"I really don't have it......" The little ghost shouted with tears on his face, my kindness, why can't anyone understand?

"Alright, let's go back first!" Jing Qi glanced at everyone, then at the little ghost, and said, "You come with me!" ”

Seeing that the main thing has said this, no matter how dissatisfied they are, they don't dare to make a mistake here.

They could only watch the little ghost enter the principal's house, and then reluctantly go back to their own house.

Although it is broken, although it leaks everywhere, it is better than standing outside.

"Tell me, what have you done to make everyone angry?" Jing Qi stood next to the fire and looked at the little ghost standing at the door who didn't dare to move.

"Chief, I just think that the house is leaking everywhere, and I want to repair the house, but they don't say that I want to harm them, and ...... also beat me ...... "The more the little ghost thinks about it, the more aggrieved he becomes."

Jing Qi couldn't help but smile, just the injury on the little ghost's face, he didn't need to say it to know that he was beaten.

Even the blood is fresh.

"How do you want to fix the house?" Jing Qi still grasped the key point, and the contradiction between the two sides may be here.

"Just put some mud on the wall, so that the wind can't get in, and when it's done, the fire in the house can be lit a little bigger." The little ghost said honestly.

"Then do you know that so much mud smeared on it may collapse the house?" Jing Qi was a little speechless.

"No, it won't! Absolutely not! "The little ghost's head shook like a rattle.

If it was just an imaginary solution, he really wouldn't have this kind of confidence.

But this solution is not an imaginary idea.

"I used this method when I was in the north, and I also used this method when I took me to the mountains to hunt in the winter a few years ago, and I said that the hut was built by him five years ago, and I followed it and wiped a layer inside and out, and the wind could not penetrate it at all, and the fire I lit in the hut was also very close to the roof, and it didn't catch up......" The little ghost told his story.

"Really?" Jing Qi was a little confused.

"Okay......" The imp nodded repeatedly.

Jing Qi thought for a while, so he said: "Then you can do it in my house first and see how it works!" ”

If you don't experience it yourself, how can you know if the effect will work?

If this method really works, doesn't that mean that he solves the problem of staying in the house?

As long as the temperature in the house can be guaranteed and more people don't get sick, for him, this is a credit.

As for the output, no one can do anything about it.

Even if the emperor blamed him, he still couldn't help it.

This kind of ghost weather is a problem for people to live, let alone get started.

Next, Jing Qi called a few people to come and help, the little ghost incarnate and the mud master.

Under Jing Qi's order, several people also had to help with resentment.

Take the soil, boil the water, mash it, and live well.

Then fill the barrel, because the temperature is too low, so the mud can not be too much at a time.

Otherwise, the little ghost hasn't finished it yet, and it's frozen here, so how can you play?

The imp skillfully played with the mud and smeared it little by little on the grass wall.

It doesn't matter what is beautiful or not, as long as it is practical.

Soon, a large mud wall was completed, and it was wet, making people feel a cool air when they stayed next to it.

You can even see that the water inside the mud has been frozen into ice, shining brightly.

After working for most of the day, the imp checked again, especially the location of the roof.

Then people gradually added fire, but it was not enough to just add fire, and a few more fires were divided in other places.

Soon, the temperature in the house went up.

The frozen water on the walls began to melt gradually, albeit slowly.

"You really don't feel the wind coming in?" Jing Qi looked at the imp in surprise.

He watched the whole process, and the mud layer was very thin, basically hanging on the grass wall.

It's still cold in the house, but it's not the same as it.

In the previous room, Jing Qi could always feel a gust of wind coming in from nowhere, and if he remained in one position, he would soon freeze.

"Chief, it's good to wait for the wall to dry some, I'll go outside now and wipe a layer, that is, the roof is full of snow, there is no way to get it, otherwise the effect will be better, and the weather is not very good now, it should be done when there is sun, it is best to let him dry it himself, there will still be some cracks when this is dry, and then just wipe it with mud." The little ghost finally showed a smile on his face again, and with the injuries on his face, suddenly, it made people feel an inexplicable sense of distress.

Jing Qi nodded, not refusing.

Plastering is not a technical job, if you really need technology, that is, don't wipe it too thick, I'm afraid that these grass walls can't hold up.

The outside does not need to wipe the roof, so the amount of work is not too large.

This time, even Jing Qi himself went into battle in person, and several people worked together, and it only took less than a quarter of an hour to complete the painting of the exterior wall.

After finishing their work, a group of people entered the house again and washed their hands in hot water.

Although it's still the same cold, it's really not to mention, it feels different.

Seems to be warmer than just now?

"Chief, it would be better if the outside wall was dry, but now I don't have that condition." The little ghost still said with a smiling face, as if he was talking a little wider, involving the wound on his mouth, and his painful expression twitched.

"And what about the roof?" Jing Qi asked curiously.

"The roof is actually not difficult, it is still like this, first smear a layer on it, mainly to prevent the fire from igniting them, and then the grass on it does not need to be too thick, rub another layer on the grass, and then spread a layer of large leaves, and then spread grass on top of the big leaves, and then wipe another layer, and then still spread large leaves, and finally start to spread more grass."

In fact, every time the thickness increases, the current roof is not thin, otherwise it will not be able to withstand the impact of rain.

And the role of mud in this is actually equivalent to the role of a layer of wind wall.

In other words, in fact, this one made by the imp is a simple version of the insulation wall.

The outer and inner layers of mud block direct wind penetration, even if there are some crevices.

After the isolation of the outer mud wall, the grass wall in the middle will carry out a new round of isolation of the incoming cold air, and finally the inner mud wall will be the last isolation.

After three processes, it is difficult for cold air to come in directly, and in the same way, the heat in the house will be reflected back after hitting the mud wall.

Even if it absorbs a certain amount of heat, the heat it absorbs is far less than the volatile heat absorbed by a grass wall.

This night, Jing Qi still woke up from freezing.

But it feels different from before, the fire in the house is also bigger, and the temperature is much higher than yesterday, mainly because it is too cold outside.

On the third day, Jing Qi finally slept peacefully.

He didn't wake up that night.

The mud walls in the house have all been dried, and a thin layer can be placed in the summer, but only half a day's work will be enough.

But now, it took three days.

Jing Qi walked outside the house to experience it, and instantly shivered from the cold, and his neck shrunk tightly.

I went back inside the house to feel it, and felt that the temperature inside and outside was at least a season apart.

It's like the temperature difference between the cold winter and the late autumn and the beginning of winter.

"Good! Great goodness! Jing Qi stood outside the house and suddenly burst out laughing.

In the past two days, the number of people suffering from wind chill in the camp has increased again, reaching as many as 1,000.

And there are more than 200 people who have a fever, although the imperial court has prepared a lot of medicinal materials in advance, but the inventory is still falling rapidly, if it continues like this, maybe it will be out of stock in another ten days and half a month.

"Come on, let the whole battalion do this!" Jing Qi ordered excitedly.

Great work! That's a big deal......
