"The weather this year is indeed colder than usual."

"Some of this charcoal is unburned!"

Xuchang Administration.

Cao Cao stretched out his hand to bake the fire raised with charcoal, and his eyes saw the heavy snow falling outside the hall, and he couldn't help but say something out loud.

Xun Yu on the side seemed to remember something when he heard this.

"My lord, as Fengyi said before, Shi Ni can be burned for heating, but this thing seems to be very extensive in the land of Hebei and Erzhou."

"Shi Nirvana? Jizhou! ”

Cao Cao was stunned when he heard this, and then raised his eyebrows.

"That's what Fengyi said, it's right!"

"I'll send a letter to Yuan Benchu immediately!"

Xuchang snowed heavily, the weather became more and more cold, after Dezhi Xiyu said that Shi Ni could be burned for warmth, Cao Cao immediately wrote to Yuan Shao, intending to exchange Shi Ni.

In this regard, Cao Cao exchanged paper, grain and grass, and Yuan Shao readily agreed.

A few days later, a large amount of black stone was transported from Jizhou to Xuchang.

Knowing that Cao Cao got a large amount of coal from Yuan Shao, Xi Yu rushed to the workshop as soon as possible.

At present, coal that is mined directly can be burned directly.

But if this thing is burned directly, it is somewhat wasteful in the current era.

For the next few days, Xi Yu remained in prison.

"I heard that Fengyi has been staying in prison recently?

Hasn't he already taught those who will be masters how to make this stone? ”

In the Xuchang Bureau, seeing that Xi Yu was not present, Cao Cao took the initiative to ask Xun Yu on the side.

The stone Ni from Jizhou is really good, and after the treatment that Xi Yu said, the temperature is much higher than that of charcoal.

Now, the entire Xuchang field, even in the Han Palace, has basically begun to use stone to replace charcoal burning.

Yuan Benchu's guy occupies a good place!

"I know what Fengyi is doing!"

Hearing Cao Cao's question, Xun Yu subconsciously responded with a smile.

Xi Yu has studied the matter of ink work, which Xun Yu has been very clear about since the original Quyuan plow and waterwheel.

"Oh, let's hear it!"

Cao Cao was a little curious.

In his opinion, Xi Yu has just been newly married, and it is normal not to come to the government office to attend, after all, there are still two wives at home!

It's just that since he didn't come to attend, he didn't stay at home, and he stayed in the prison all the time, so Cao Cao couldn't understand it.

Isn't the matter of Shi Ni already settled?

What is the purpose of staying in prison?

"I heard Fengyi say that he said that he wanted to do what floor heating in the house, once and for all, there was no need to regenerate the stove fire in the future!"

Well?

Underfloor heating?

Fengyi is studying this, in such a cold winter, how can it be possible to keep warm at home without a fire?

"Wen Ruo, it's nothing important this time, why don't we go to the prison and see what Fengyi is doing?"

Cao Cao was a little curious.

He is naturally very clear about Xi Yu's ability.

The matter of the curved plow and the waterwheel, let him think about it, he couldn't think of it, and he naturally couldn't figure out what kind of floor heating was right now.

However, since I don't understand it, fortunately, it is better to go and see it directly.

If you really don't need to make a fire, you have to get a set for your own house.

In this cold winter, I just rely on the fire to keep warm, and it is still a little cold after all.

Even though charcoal has been replaced with stone, you can't put a fire next to your bed!

got Cao Cao's meaning, Xun Yu did not refuse.

Now that the New Year is approaching, there is not much to do in Xuchang.

Originally, I was worried about the high price of charcoal in the cold winter, but now because of the stone, it has almost been solved.

After refinement, Shi Ni has now started from Xuchang and is being sold all over Yanzhou.

Even ordinary people can also hoard some stone nirvana at home.

The two walked out of the government office together, and walked all the way towards Xuchang's general supervisor.

Not much.

After arriving at the prison, he found out that Xi Yu was not here this time.

After asking the guards on duty, Cao Cao and the others learned that Xi Yu had led a group of generals to his house early since the day before yesterday.

At this time, inside the theater house.

The ground in the main hall of the entire theater has been excavated, and a strangely shaped iron pipe has been buried in the ground under the command of Xi Yu.

The drama on the side was a little stunned.

"Ah Yu, this thing can really warm up the house?"

Since the cold winter came, Xi Zhicai found that his younger brother had been studying strange things at home during this time.

Now, even the entire general is about to move into his home.

"Sir, it's really a whimsy!"

After Ma San, who had been promoted to be the chief eunuch, buried the pipe, he couldn't help but open his mouth to praise it.

These words were highly recognized by the general eunuchs on the side.

These craftsmen themselves regard the Mo family as their ancestors, although Xi Yu has never admitted anything.

But these craftsmen have long regarded Xi Yu as the descendant of the Mo family.

"Ma San, did I ask you to help make the flush toilet before?"

Taking advantage of the time to install floor heating by the way, Xi Yu casually asked Ma San on the side.

"Sir, it's done, we have also made the kind of tap water you said, do you want to help you install it in the house?"

Ma San responded, and after Xi Yu nodded and agreed, the entire master craftsman who would be the supervisor hurriedly followed suit.

Things like running water and flush toilets have long been handy under the teaching of Xi Yu.

It didn't take much effort, and the whole theater was completely new.

When Cao Cao and Xun Yu arrived at the opera house, the master craftsmen who would be the prisoners had already left.

At this moment, in the main hall of the operatist, there is a square table in front of Xi Yu.

The main hall door was open, as if a light breeze was blowing.

Xi Zhicai was dressed in a thin shirt, and he seemed to be a little warm, and even the robe with his chest was a little open.

Xi Yu on the opposite side was also wearing a white shirt.

The two brothers sat opposite each other, on the left and right, sitting cross-legged on Zhao Yun and Dian Wei respectively.

Zhao Yun was also wearing a thin shirt, and Dian Wei on the opposite side was with open arms.

On the square table, the sound of mahjong colliding is endless.

After Cao Cao and the others entered through the gate of the opera, they passed the corridor and raised their eyes to see that the main hall of the operator was open.

In the eye, Dian Wei's broad muscles instantly came into view.

"Wen Ruo, I'm not mistaken!"

Cao Cao was a little stunned, just a few steps away, and Xi Yu and the others not far away were dressed as if they were in the middle of summer.

And at this moment, he is covered in clothes, and his whole body wants to be wrapped tightly.

The wind blowing from the long pavilion was still a little cold, and Cao Cao was a little numb.

Xun Yu was also a little stunned.

The situation in front of him was only for a moment, and he already understood.

I never thought that what Fengyi said about floor heating turned out to be true.

Stumped the inside of the house, is it really like a warm spring in March?

The two of them were a little stunned, and in the whole hall, the sound of four people playing mahjong had come out of it.

When Cao Cao took Xun Yu to the door of the main hall, he obviously felt a warm wind sweeping out of the main hall.

The oncoming warm breeze makes people's brows can't help but stretch out.

"This ......"

After Cao Cao and the others appeared outside the main hall, the four people in the hall naturally noticed it.

Stopping the mahjong in their hands, the four of them looked out of the hall.

Zhao Yun got up and saluted for the first time, and Xi Zhicai on the side also greeted him with a grin.

"It's coming!"

Xi Yu nodded towards Cao Cao.

In this kung fu, Cao Cao and Xun Yu stepped into the main hall of the actor without hesitation.

The warm breeze in the room dispelled the chill in an instant.

"It's really like a warm spring in March!"

Cao Cao opened his mouth and sighed, he didn't expect that in just a few days, Xi Yu would make such a thing, it was really surprisingly tight!

Xun Yu took off the big hat on his body, and sat down in the main hall without saying anything.

"I kind of understand why Fengyi didn't go to the government office these days."

The room was so warm that even he didn't want to go to the government office to report.

"If Fengyi doesn't dislike it, I'll let people move the official document into your house tomorrow!"

Xun Yu couldn't help but speak.

Cao Cao's kung fu also unraveled the big trick on his body.

"Fengyi, there is such a good thing, why didn't you say it earlier?"

Cao Cao meant something, and Xi Yu was a little helpless when he heard this.

The floor heating thing was also made by him temporarily.

It takes a lot of time just to lay the iron pipes on the ground.

At present, the prison will only be made in one set, and the others are naturally not available now.

According to Xi Yu's physique, he is not afraid of cold and heat at all.

Still, he is him, and the others are others.

Such a cold winter, for Gan Mei and Cai Yan, even with Xi Zhicai and others, it is a little difficult after all.

For this reason, he took the time to have the general supervisor build a set of underfloor heating equipment.

After Cao Cao said this, Xun Yu on the side also moved a little.

Although Xun Yu doesn't care much about some things, floor heating is a facility that can make the home warm up in winter.

Who doesn't want it?

Cao Cao felt that Xi Yu was a little unkind, but before Xi Yu could speak, Dian Wei on the side couldn't help but explain.

"Lord, I heard those who will be the eunuchs say that this set of floor heating equipment will cost my husband a lot of money!"

Before Dian Wei's words fell, the corners of Cao Cao's mouth couldn't help laughing.

"Why, I'm so common, I can't get some money!"

Xun Yu's expression on the side has not changed much, and the Xun family's money is still not lacking.

If you can get a set of these things for a little money, you can't do it.

"Fengyi, how much does this floor heating cost? You name it! ”

Hearing that it was just some money, Cao Cao didn't care too much about it at all.

After saying this, Xi Yu immediately spoke.

"Brother, it's not about money, it's just that the iron pipes needed for this floor heating need to be specially manufactured, so it costs some money."

"Actually, it's more than that, it will take some time, and now this set will be completed soon after being a prisoner."

"If the two brothers are interested, I'm afraid they will have to contact the general as a prisoner, and it will take some time!"

After listening to this explanation, Cao Cao didn't pay much attention to it.

It's just that the news that the actor's cold winter is like a warm day finally spread, and even Liu Xie, who was in the Han Palace, knew about it.

The Han Palace in Xuchang has not yet been completed, and according to the original plan, it is almost to be built according to the scale of the old palace in Luoyang.

Nowadays, there is only the Xuanshu Hall where Liu Xie lives, and the Chengguang Hall of the Chaohui and several palaces in the harem.

Even if there is a fire in the Han Palace, it is obviously a little cold in the cold winter.

Knowing what floor heating there is in the theater can make the cold winter like a warm day.

Liu Xie immediately took the queen Fu Shou and the attendants to the opera.

For Liu Xie, the Son of Heaven, to come in person, Xi Yu was somewhat surprised.

However, who let the other party be the current son of heaven, although he was a little unhappy in his heart, he couldn't refuse.

In the main hall of the dramatist, after saluting Liu Xie, Xi Yu felt a little helpless.

His two wives took the initiative to take on the responsibility of entertaining the queen Fushou.

And with Liu Xie's coming, it didn't take long for the courtiers and generals of the entire opera family to follow.

Fortunately, after living in Xu County, with his status as Xi Zhicai, the entire opera family's area is not too small.

A main hall is about to become a court meeting in the Han Palace because of Liu Xie.

At this moment, inside the main hall.

In the past, there were so many cases, and Xi Yu gave the chief to Liu Xie, and there were civil and military officials on both sides.

Cao Ying's ministers naturally came.

Xi Yu and Cao Cao and others sat on one side, and Tai Lieutenant Yang Biao sat on the other side with Dong Chengyu and the rest of the famous officials.

"I heard that this floor heating thing was researched by Xi Qing, and Xi Qing's idea is really eye-opening!"

Liu Xie was quite emotional, and after feeling that the main hall of the actor was warmer than the fire rising in his Han Palace, he couldn't help but open his mouth to praise.

Hearing this, before Xi Yu could respond, Dong Cheng at the bottom opened his mouth and began to be angry.

"It seems that Dasi Nong didn't take His Majesty in his eyes, such a unique thing, why don't you dedicate yourself to Your Majesty and dare to enjoy it alone?"

Dong Cheng opened his mouth to ask for the guilt, and after these words came out, Xi Yu's brows couldn't help jumping.

Cao Cao, who was sitting on the side, was also happy.

You Dong Cheng envy yourself, but now you are talking about things through His Majesty's affairs, which is really disgusting.

This floor heating is now only available to dramatists.

What's more, this thing was made up by Fengyi himself, whether he gave it to the Son of Heaven or not, it was Fengyi's business, what does it have to do with you Dong Cheng?

As Dong Cheng spoke, some of the officials on the side also chimed in.

Chief Liu Xie waved his hand when he heard this: "General Dong, what are these words, this thing belongs to Xi Qing, and it has nothing to do with me!" ”

Liu Xie didn't get angry because of this, he just had some feelings, not to mention, he still wanted to win over Xi Yu!

He heard that this floor heating would be used as a prison, and he had already begun to build it.

When the time comes, there will naturally be one in the Han Palace.

As Liu Xie spoke, Dong Cheng didn't say anything.

After all, Liu Xie himself doesn't care, if he is calculating, it will not be the same thing.

Because Liu Xie was there, it happened to be near noon, and it was time to eat.

If Liu Xie didn't leave, the courtiers naturally had no intention of leaving.

"When I first came to Xuchang, I heard in Yanzhou that Xiqing is good at tinkering with food, and I heard that the cooking of braised pork came from Xiqing."

"Today, I can't say that I want to taste the delicious food of Qing's house, and I hope Qing doesn't care!"

Liu Xie blatantly wanted to stay and eat, but it was not easy for Xi Yu to drive the other party away.

Cao Cao and the others also planned to stay, and even Yang Biao and the others naturally did the same.

Xi Yu pursed his lips and glanced at everyone.

"It doesn't hurt if Your Majesty wants to stay, it's nothing more than adding a pair of chopsticks to the house!"

"It's just that there aren't too many chopsticks in the minister's house, and I'm afraid the captain and the others won't be able to entertain them!"

In front of Liu Xie, Xi Yu was not polite.

You rub the rice, you rub the rice, but I don't care about these people, you see this way!

Liu Xie was stunned for a moment, but he didn't expect Xi Yu to say this, and Cao Cao was not the slightest surprised.

"Then who, Dian Wei, you go outside and tell Xu Chu, just say that I stayed at the opera house to eat today, and let Xu Chang help send more things over!"

After saying this, Cao Cao looked at Xun Yu and the others on the side, and then his eyes fell on Xi Yu.

"Fengyi, Wen Ruo and I will solve it ourselves, you don't have to worry about it!"

As soon as Cao Cao said this, only Yang Biao and others remained.

And when Liu Xie heard Cao Cao say this, his eyes also looked at Yang Biao and the others: "Taiwei, what Xi Qing said is not unreasonable, Sikong can solve it by itself, you can solve it by yourself!" ”

Liu Xie: This means that he doesn't care about Yang Biao and others.

It stands to reason that if the host doesn't entertain, there is no reason for the guest to stay.

However, the situation is different today.

Liu Xie stayed, Yang Biao and the others naturally didn't want to leave like this, who knows what will happen after they leave!

"Hmph, is this how the dignified Grand Si Nong treats visitors?"

Yang Biao snorted coldly.

Before Xi Yu could speak, Cao Cao on the opposite side couldn't help but sneer.

"Tai Lieutenant said something wrong, I didn't hear that Da Si Nong invited Tai Wei to come as a guest!"

"Wait, isn't it uninvited?"

As soon as Cao Cao said this, Yang Biao's face was already a little dark.

Immediately after, I don't know who on the other side shouted again.

"What Captain, can't you even afford to eat?"

These words are a bit harsh, even Yang Biao almost couldn't sit still, if it weren't for Dong Cheng on the side dragging him, Yang Biao at this moment would have been unable to help but walk away.

Yang Biao suppressed his anger, and Dong Cheng on the side had already given an order to the officials around him, and after a short time, someone brought over a set of utensils to eat.

This kung fu, Yang Biao looked at Cao Cao, and couldn't help but speak out when he spoke.

"I heard that Sikong has helped His Majesty choose the palace guards some time ago, I don't know if this matter is true?"

Yang Biao's words meant something.

The selection of the guards of the Han Palace should have been the duty of the guards.

At this moment, the meaning of Yang Biao's words obviously accused Cao Cao of being a commonplace, overstepping his bounds, and not taking the Son of Heaven in his eyes.

Even if the former guard captain had already died in the process of escorting the Son of Heaven, it stands to reason that it would not be Cao Cao's turn to intervene now.

He is the captain of the Han Dynasty, and now he is the first of the three dukes, and Cao Cao, who is also the third duke, is not higher than him in terms of status.
