With a strain of his hand, the captain of the Nafu soldiers approached a house, unmounted his skis, and scanned his gloved hand into the outline of the house to find the eaves.

Jumping down the eaves of the house, he climbed onto the roof of the house, walked over to what appeared to be a chimney, and drew his knife.

Dangdang~

Just two times before the light scraping, there was a sound of knocking on the masonry.

A second sweep reveals the grayish-yellow color inside.

"Thousands of households, it's red bricks, inferior red bricks."

The voice of the captain of the government was full of surprise, red bricks are only available in Lantian County, and they are not sold out for the time being, which proves that this family bought something from Lantian County, and the people of Lantian County came to build it.

The only things that can use chimneys are honeycomb coal stoves and kangs.

Sheng Chong knew what to expect and shouted below: "Climb up and see if the chimney is blocked?" Is there any hot air coming out? ”

"Hey~"

The captain of the army put away his waist knife and climbed the chimney with both hands and climbed up carefully.

"Qianhu, there is heat coming out, and there are people inside."

"Very well, come down.

Everyone spread out, how many houses have chimneys, make a mark. ”

"Yes."

The soldiers of the Thirty Liang Wangfu stepped on their skis and scattered, Sheng Chong found Jiang Ming, who was shaving snow, and said:

"Jiang Qianhu, this house doesn't need to be planed first, they should be alive and well, you planed those houses without chimneys first?"

"Why?"

Jiang Ming stopped what he was doing, his hands were already shivering from cold, and his eyes were full of doubts.

Sheng Chong looked at Jiang Mingtong's red hands, thinking that gloves should be added to the next batch of rescue supplies, but he said:

"People with chimneys are absolutely fine with keeping warm, and it's okay to be buried for three or two days, and it's hard to say about those houses without chimneys."

"Really? Brother Sheng, are you sure? ”

"Sure.

This chimney is connected to a kang and a honeycomb coal stove, which was invented by His Royal Highness King Liang and is only available in Lantian County. ”

"Really?"

Jiang Ming was still a little unconvinced, and didn't let his subordinates stop, Sheng Chong knew that he was going to verify his words, shrugged his shoulders and let go to the side to check the situation in the village.

There are about 200 houses that can be seen, and only three are relatively tall, but all of them are bungalows, and it is easy to see whether there are chimneys or not in such a snow-covered situation.

And soon the soldiers under his command came to report.

"Lord Qianhu, there are a total of 104 chimneys, all of which are still hot, there should be no dead people, but the snow is thick, and I can't hear the movement outside."

"Well, that's fine, let's go unload the sled and get ready to go back and deliver the next batch.

This time, I will also go back and apply for some new supplies from His Highness. ”

"Yes."

In the indignant eyes of the military households in Xi'an, Sheng Chong and the others began to unload the goods.

"Boss, these bastards of Liangwangfu really have no conscience."

"Hmph~ There are no relatives buried here, they must have nothing to do with themselves."

"Boss, how could King Liang be such a benevolent person, how could there be such a cold-blooded soldier?

I don't know if King Liang still recruits government soldiers, let's go and replace them. ”

Several hundred officers leaned to Jiang Ming's side and couldn't help complaining that Jiang Ming's face was also a little dark, but they still reprimanded in a low voice:

"They don't talk nonsense, dig quickly, and save people quickly."

"Boss~ We've dug up the window here, do you want to break the window and go in?"

", broken windows! Break the window immediately. ”

Click~

With a crisp sound, a window was kicked open, and several military households rushed in, and then there was an exclamation.

"Ergouzi, you're back, but the snow has stopped."

"Dad, are you alright? Is it so warm at home? ”

"Haha~ At this time, the honeycomb coal stove, a specialty of 52 villages in Lantian County, can be warmed as long as it is burned, and it can also cook things.

Ergouzi, are you hungry, there is still some steamed wheat rice in the pot. ”

When Jiang Ming came in, he saw a very warm scene, a soldier in the military household was pulled by the old father to show off the honeycomb coal stove;

The rest of his family was crammed into the square kitchen, with a pile of black briquettes standing tall next to it.

Jiang Ming hurriedly interrupted the family's reminiscence: "Daddy Li, have all the people in your village installed this honeycomb coal stove?" ”

"That's not true, Li Sanqian and Li Siwan still have ......"

The father of the Li family reported seven names in a few cases, and Jiang Ming was a little anxious.

"Daddy Li, take us to identify these families."

"Okay, these guys who pick the door are probably going to be frozen into grandchildren."

Daddy Li complained while wrapping himself in thick clothes and sneaking out of the window to lead the way.

More than two feet of snow sealed the house, but it was not as simple as freezing people into grandchildren!

When Li Sanqian's house was dug up, there was a smell of rotten eggs.

Smelling this smell, Jiang Ming's face immediately changed.

He quickly found the location of the kitchen according to experience, and as soon as he pushed the door open, his face sank.

A family of five was lying on the ground, and in front of them was a fire with unburned briquettes and firewood.

Although he already had the answer in his heart, he still stepped forward and touched these people,

Touching the corpses, to be precise.

All five of them had weird smiles on their faces, and their bodies were already stiff!

"Carboniferous poison! They were poisoned by burning charcoal and died.

Dig up the others. ”

Jiang Ming just looked at the weird smile and knew that it was coal poisoning.

As long as people with experience are not willing to burn coal in winter, because while heating, they are also taking death!

The ancients didn't know about carbon monoxide and carbon dioxide poisoning, but they would conclude that they knew that coal could not be burned indoors and could not be used for cooking, and they thought that coal was poisonous.

This time, Zhu Gaoxuan made honeycomb coal, and especially emphasized that the coal stove is the key, and the poisonous gas must be discharged with a chimney.

He couldn't explain carbon monoxide and carbon dioxide, and it was easiest to explain it directly with poison gas.

And all the people and exiles in Lantian have been well educated, and know that there must be a chimney, and the chimney must be checked at any time before coal can be burned.

But this is not common outside of Lantian.

Three of the seven families have died, dying of coal poisoning, and the remaining four have not died, but have been frozen, all with varying degrees of wind chill.

Jiang Ming found Sheng Chong, dragged him to Li Sanqian's house, and asked him how some people who also burned briquettes were some dead and some were fine.

"It's very simple, his family didn't discharge the poisonous gas, and the briquettes invented by His Royal Highness just made it easier for the charcoal to burn, and there should still be poisonous gas, and the poisonous gas must be discharged with a chimney."

"How big a chimney is?"

"Definitely.

The coal stove is very easy to make, as long as it is disassembled, ordinary people will make it, but it is not so easy to make a qualified chimney, even in Lantian only so many people can make it. ”
