In the early morning of that day, before dawn, the officials and officers and men of the northern region went to the nearest coal mines one after another to start the coal mining project.

At the same time, when the gates of Northland City were opened, two groups of people in ragged clothes, withered and thin like refugees stepped into Northland City.

"Name."

"Chapter pay." "Department of Literature."

"Identity."

"The Inkman."

The person in charge of registration at the gate of the city glanced at the two leaders, and saw that one of them was ragged and skinny, and the other was unclothed and had two of his toes frozen, and he could not help but be a little suspicious.

"Are you really the Ink Masters?"

Zhang Fei's eyes widened, "With this kind of identity, can you still deceive people?" ”

The Faculty of Literature was much kinder, and he explained: "We were invited by the general to come to the aid of the Northland. ”

After a pause, he said again: "I wonder if there are any people in the Northland City who have changed to Chen Xu?" We are all in the same family. ”

When Zhang Yu heard this, he immediately scolded: "That traitor who tends to be inflammatory......"

Before he could finish scolding, the guard looked at him coldly, "Bold, you dare to insult Shang Fangling!" ”

Zhang Yu was stunned.

Shang Fang Ling?

Chen Xu's old thing turned out to be Shang Fangling?

He couldn't help asking, "Dare to ask, what did he do that was so valued by the general?" ”

The guard immediately showed a proud expression, "So that you know that the Quyuan plough that is used by the common people in the north today, the improved tables and chairs, and the hemp paper that has been popular all over the world recently, are all from Shang Fangling's hands!" ”

Zhang Yu was really shocked at this time.

Quyuan plough and tables and chairs aside, the hemp paper was actually made by Chen Xu?

Why didn't he believe it!

Zhang Yu wanted to continue to ask, but the Wen Department said: "We are really ink people, if you don't believe it, you can let Lord Shang Fang Ling come to see us." ”

The guard shook his head and said, "It's unfortunate that you are here, Shang Fangling is not in the city. ”

"Oh, where did he go with such a heavy snow?" The Department of Literature asked.

Guard: "It has been snowing in the north recently, the princess is kind and sympathetic to the people, and specially ordered Shang Fang to make them research something called a fire kang, which can resist the cold, and Shang Fang ordered the Lord to take Shang Fang's people to various places and teach them to make fire kang." ”

Zhang Yu and the Department of Literature spoke at the same time, "Huokang? ”

The guard nodded, but he didn't want to say more, "This thing is easy to make, and it can be used by ordinary people, and with it, no one will freeze to death." ”

Zhang Yu was a little unconvinced, "Can you use it at home?" ”

The guard's eyes widened, "The princess has an order, although this thing is simple to make, but there is a shortage of manpower, and it takes time to plate the kang, so we should focus on the common people first, and we and other officials can't compete with the people, so we have to wait until the back to make the plate." ”

This simply overturned their perception of superiors.

Zhang Yu said to himself, could it be that I am too narrow-minded and look down on the Northland?

Department of Literature: "We are all ink masters, Chen Zhi is proficient, we will all know, please inform me on my behalf, I ask to see Her Royal Highness the princess, I can also lead my disciples to help the common people Pankang!" ”

When Zhang Yu heard this, he was not reconciled, and immediately said: "I can wait!" ”

The guards saw that they were convincing, and that the Northland was indeed short of talents, so they immediately arranged for someone to go to the palace to report the news.

Half an hour later, the two ink warriors came to the palace.

"Meet Her Royal Highness Princess Jinyang!"

The crowd bowed and bowed.

Princess Jinyang asked them all to sit down, and they had never sat on a chair before, so they were a little uncomfortable, so they knelt down and sat down.

When Zhang Yu asked about the fire kang, Princess Jinyang introduced Jinyan, and then it was Jinyan's home field.

She drew drawings on paper and explained the principle, and then showed everyone a model of a kang made of clay.

"That's how it works, you know?" Jin Yan asked.

Compared with something that had never been seen before, Zhang Xiang and the Department of Literature were more interested in Jinyan.

This little master, who is only three years old, has a clear speech, speaks extraordinarily, and is very clear about many principles of the fire kang, and in order to make it easier for them to understand, he can even draw inferences about some other things.

Zhang Yu glanced at the Department of Literature quietly.

What kind of curved plow, what kind of compost and what kind of hemp paper, although it was made by Chen Xu's master and apprentice, but I am afraid that there are other people who put forward ideas.

And the more they looked at Jin Yan, the more certain they were for their guesses.

In the past two years, many changes have taken place in the Northland, but I am afraid that they are all inseparable from this little master.

Princess Jinyang: "You are tired of traveling and traveling, and you should have set up a banquet to entertain you, but now the snow is non-stop, and the situation is really critical, so I have to ask you to help the north." ”

Zhang Yu immediately said: "I waited thousands of miles to come, just to help the north, this time there are such things that can save people from freezing to death, so naturally we must hurry up and make them without delay." ”

Wen Department: "I don't need a banquet, I just need some dry food to take on the road, and my disciples and I can set off now." ”

Zhang Yu glared at the Department of Literature, hasn't this old man always been an indisputable character? Why is it so radical all of a sudden?

Could it be that he was stimulated by Chen Zhi as Shang Fangling and respected by the Northland people?

Slander is slander, he is already a competitive person, and he is not far behind at this moment, so he immediately asks for his life.

Princess Jinyang was a little stunned.

She had already asked people to prepare the meal, and after inviting everyone to eat, she arranged for the soldiers to carry dry food on their backs and escort these ink writers to various places.

As soon as the two Inkmen had left, messengers came with a whip.

He carried a few black stones with him, which were the coal that Jin Yan was looking for.

Jin Yan immediately had the coal smashed and brought a brazier, and put some crumbs and small pieces of coal into it, and after a while, everyone saw the black stone burning.

And it releases much more heat than charcoal.

Xiao Jin'an squatted beside the brazier and put his hand on top of the brazier, he tried to catch the flames, but was dragged away by Xiao Quji.

Everyone looked over worriedly, but saw that his face was burned red.

Xiao Jinan rubbed his face, struggled to take off his clothes again, and was still complaining in his mouth, "Mother, it's so warm!" ”

Hearing his words, Princess Jinyang was relieved.

That night, Xiao Budo and Zhong Xing also returned to the palace.

It was snowing heavily, and both of them had a thick layer on their bodies, and their hair was frozen.

But as soon as they entered the main hall, the two immediately noticed the difference.

"Why is it so warm?"

When Zhong Xing spoke, Zhang An had already stepped forward and took off the big coat on their bodies, and when he went outside to shake the snow, he found that there was a thin young man standing under the eaves, it was Chen Sui.

At this time, Zhong Xing came out of it again, "Chen Sui, come close to me." ”

Chen Sui's eyes widened and he looked at Zhong Xing suspiciously, wondering why he was dressed so thinly.

Half an hour later, when he walked into the main hall and sat around the charcoal stove, he finally understood.

There was a bright light in his eyes.

Coal?

Ondol?

With these two things, no one will freeze to death this winter, right? (End of chapter)
