We agreed that you, a weak strategist, would fight against three heroes by yourself?

"This year's weather is indeed a bit colder than in previous years."

"These charcoals are a bit unburnt!"

Within the Xuchang Yamen Office.

Cao Cao stretched out his hand to light the charcoal fire. He looked at the heavy snow outside the hall and couldn't help but say something.

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

"Lord, as Fengyi said before, stone nirvana can be burned for heating purposes. However, this thing seems to be very widespread in the area where Hebei merged with the two states."

"Shi Nie? Jizhou!"

Cao Cao was stunned when he heard the sound, and then raised his brows.

"That's what Feng Yi said, and it's absolutely correct!"

"I will send a letter to Yuan Benchu ​​immediately!"

It snowed heavily in Xuchang and the weather became increasingly cold. After learning from Xiyu that Shi Nie could be burned for warmth, Cao Cao immediately wrote to Yuan Shao with the intention of exchanging Shi Nie.

In response, Cao Cao offered paper, grain and other items in exchange, and Yuan Shao happily agreed.

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

After learning that Cao Cao had obtained a large amount of coal from Yuan Shao, Xi Yu rushed to Jiang's workshop as soon as possible.

Although the coal currently mined directly can be burned directly.

But if this thing is burned directly, it would still be somewhat wasteful in today's era.

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

"I heard that Fengyi has been staying in Jiang Zuo Prison recently?

Didn't he already teach those who would be great craftsmen how to make this stone? "

Inside the Xuchang Yamen Office, seeing that Xi Yu was not present, Cao Cao took the initiative to ask Xun Yu who was standing next to him.

The stone nirvana obtained from Jizhou is indeed good. After being processed as Xi Yu said, the temperature is much higher than that of charcoal.

Nowadays, the entire Xuchang market, and even the Han Palace, have basically begun to use stone nirvana instead of charcoal for burning.

That guy Yuan Benchu ​​occupies a good place!

"I do know what Fengyi is doing!"

After hearing Cao Cao's question, Xun Yu subconsciously smiled and responded.

Xi Yu had a lot of research on the work of ink workers. This was already very clear to Xun Yu from the original Quyuan plow and waterwheel incident.

"Oh, tell me!"

Cao Cao was a little curious.

In his opinion, Xi Yu had just gotten married, so it was normal not to come to the government office to attend. After all, he still had two wives at home!

However, since he did not come to attend and was not at home, but stayed in the general's prison, Cao Cao was a little confused.

Hasn’t Shi Nie’s matter been resolved?

Why are you still serving as a prisoner?

"I heard from Fengyi that he wanted to do some floor heating in the house, once and for all, so that he doesn't have to have a fire in the future!"

Um?

Floor heating?

Fengyi is studying this. How is it possible that in such a cold winter, the home can be heated without a fire?

"Wen Ruo, there's nothing important this time. Why don't we go to the prison to see what Fengyi is doing?"

Cao Cao was a little curious.

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

He couldn't think of things like the plow and the waterwheel, and naturally he couldn't figure out the floor heating at the moment.

However, since I can’t figure it out, luckily I might as well just go and take a look.

If you really don't need to light a fire, you must get one for your house.

In the cold winter of the twelfth lunar month, it was still a bit cold after all, just relying on the fire to keep warm.

Even though charcoal has now been replaced by charcoal, the fire cannot be placed next to the bed!

After hearing what Cao Cao wanted, Xun Yu did not refuse.

Now that the New Year is approaching, Xuchang doesn't have much to do.

I was originally worried about the high price of charcoal in the cold winter, but now it is almost solved because of Shi Nie.

The refined Shi Nie has now been sold in various places in Yanzhou starting from Xuchang.

Even ordinary people can hoard some stone nirvana at home.

The two of them left the government office together and walked towards the general supervisor of Xuchang.

Not long after.

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

After asking the guards on duty, Cao Cao and the two found out that Xi Yu had led a group of generals and supervisors to his home early the day before yesterday.

Inside the theater at this time.

The ground in the entire theater hall has been excavated, and strange-shaped iron pipes were buried in the ground following Xi Yu's command.

Xi Zhi next to him was a little stunned.

"Ayu, can this thing really warm up the whole room?"

Since the cold winter came, Xi Zhicai discovered that his younger brother spent a lot of time researching weird things at home.

Now, the entire general and supervisor are about to move home.

"Sir, you really have a fantastic idea!"

After Ma San, who had been promoted to general supervisor, buried the pipeline, he couldn't help but open his mouth and praise it.

This statement was highly recognized by the generals and supervisors nearby.

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

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

"Ma San, have you done the flush toilet I asked you to help me with before?"

Taking advantage of the time to install floor heating, Xi Yu casually asked Ma San beside him.

"Sir, it's done. We've also prepared the tap water you mentioned. Do you want to help you install it in your house?"

Ma San responded, and after Xi Yu nodded in agreement, the entire supervisory staff hurriedly started working again.

Things like running water and flush toilets have long been handy to the supervisor under Xi Yu's guidance.

It didn't take long for the entire theater to take on a completely new look.

When Cao Cao and Xun Yu arrived at the theater, the master craftsmen who would be in charge had already left.

At this moment, in the main hall of the opera house, a square table of medium or small size was placed in front of Xi Yu.

The main door of the main hall was open, and a gentle breeze seemed to be blowing.

Xi Zhicai was wearing a thin shirt, and he seemed to be a little warm, even the robe on his chest was opened a little.

Opposite Xi Yu is also wearing a white shirt.

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

Zhao Yun was also wearing a thin shirt, while Dian Wei opposite him had his arms open.

On the square table, the sound of mahjong clashing can be heard endlessly.

After Cao Cao and Cao Cao entered the theater through the main gate, they passed through the corridor and looked up to see the main hall door of the theater open.

Upon entering the eye, Dian Wei's generous muscles immediately caught his eye.

"Wen Ruo, am I right?"

Cao Cao was a little stunned. He was only a few steps away. Not far away, Xi Yu and others were dressed as if they were in midsummer.

But at this moment, he was covered in fur clothes and a big cloak, and his whole body wanted to be wrapped tightly.

The wind blowing from Changting was still a bit cold, and it made Cao Cao feel numb.

Xun Yu was also a little stunned.

He understood the situation in front of him in just a moment.

I never thought that what Fengyi said about the floor heating was actually true.

Is it hard to believe that the interior of that house really feels like warm spring in March?

The two of them were a little dazed, and the sound of four people playing mahjong could be heard from inside the hall.

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

This oncoming warm wind makes people's brows uncontrollably stretch.

"this……"

After Cao Cao and 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 outside the hall.

Zhao Yun immediately stood up to salute, and Xi Zhicai next to him also grinned and said hello.

"coming!"

Xi Yu nodded towards Cao Cao.

At this moment, Cao Cao and Xun Yu entered the theater hall without hesitation.

The warm air in the room dissipated the chill in the body in an instant.

"It's really as warm as spring in March!"

Cao Cao opened his mouth and sighed. He didn't expect that in just a few days, Xi Yu would come up with something like this. It was really surprising!

Xun Yu took off his cloak and sat down in the main hall without any explanation.

"I finally understand why Fengyi hasn't gone to the government office these days."

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

"If you don't mind Fengyi, I will have the official documents moved into your home tomorrow!"

Xun Yu couldn't help but speak.

Cao Cao then took off his cloak.

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

Cao Cao had something to say, and Xi Yu felt helpless when he heard this.

The floor heating was something he temporarily asked his general to supervise.

Just laying the iron pipes on the ground will take a lot of time.

At present, the supervisor has only made one set, and of course there is no other one.

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

However, he is who he is and everyone else is everyone else.

Such a cold winter was a bit difficult for Gan Mei, Cai Yan, Xi Zhicai and others.

For this reason, he took the time to have Jiang Zuo supervise the production of a set of floor heating equipment.

After Cao Cao said these words, Xun Yu next to him also felt a little moved.

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

Who doesn't want that?

Cao Cao felt that Xi Yu was a little unkind, but Dian Wei, who was standing next to Xi Yu before he could say anything, couldn't help but explain.

"My lord, I heard from the general eunuchs that this floor heating equipment cost my husband a lot of money!"

Before Dian Wei finished speaking, Cao Cao couldn't help laughing.

"Why, my dignified Sikong, I'm so confused that I can't come up with some money!"

Xun Yu's expression next to him didn't change much. The Xun family still had plenty of money.

If you only need to spend a little money to get a set of such things, it wouldn't be a bad idea.

"Fengyi, how much does this kind of floor heating cost? Tell me the number!"

Hearing that it was just a waste of money, Cao Cao didn't pay much attention at all.

After saying this, Xi Yu immediately spoke.

"Brother, it's not about money. It's just that the iron pipes needed for floor heating need to be specially made, so it costs a lot of money."

"Actually, more importantly, it will take some time. It won't take long for the supervisor to complete this set now."

"If the two brothers are interested, I'm afraid they have to contact the general supervisor. It will take a while!"

After hearing this explanation, Cao Cao didn't care too much.

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

The Han Palace in Xuchang has not been completed yet. According to the original plan, it was almost to be built according to the scale of the Luoyang Old Palace.

Nowadays, there are only the Xuanshi Hall where Liu Xie lives, the Chengguang Hall where the court is held, and several palaces in the harem.

Even though there was a fire in the Han Palace, it was still obviously a bit chilly in the cold winter.

I learned that there is floor heating in the theater house that can make the cold winter feel like a warm day.

Liu Xie immediately took Queen Fushou and his attendants and went straight to the theater.

Xi Yu was somewhat surprised that Emperor Liu Xie came in person.

However, who made the other party the current emperor? Although he felt a little unhappy, he could not refuse.

In the main hall of the opera house, after bowing to Liu Xie, Xi Yu felt helpless.

The two wives of their own took the initiative to take on the responsibility of entertaining the Queen Fushou.

As Liu Xie arrived, the number of courtiers and generals from the entire drama family soon increased.

Fortunately, after moving into Xu County, with his and Xi Zhicai's status, the entire theater's area was not too small.

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

At this moment, in the main hall.

In the past, there were so many tables placed on the table. Xi Yu gave up the chief position to Liu Xie, and there were hundreds of civil and military officials on both sides.

Naturally, the ministers from Cao Ying also came.

Xi Yu, Cao Cao and others were sitting on one side, while Taiwei Yang Biao and the other officials named by Dong Chengyu were sitting on the other side.

"I heard that this ground-warming thing was researched by Xi Qing. Xi Qing's idea is really eye-opening!"

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

Hearing this, before Xi Yu could respond, Dong Cheng opened his mouth and started to get angry.

"It seems that Da Si Nong doesn't take His Majesty seriously. Why don't you dedicate such a unique gift to Your Majesty? How dare you enjoy it alone?"

Dong Cheng opened his mouth to ask for guilt. After these words came out, Xi Yu's brows couldn't help but jump.

Cao Cao, who was sitting next to him, was also very happy.

You, Dong Cheng, are envious of yourself, but now you are using His Majesty's affairs to make excuses. It is really disgusting.

Nowadays, only dramatists have this kind of floor heating.

What's more, this thing was tinkered by Fengyi himself. Whether it is given to the emperor or not is a matter for Fengyi. What does it have to do with you, Dong Cheng?

As Dong Cheng spoke, some of the officials nearby also followed suit.

The chief Liu Xie heard this and waved his hand: "What are you talking about, General Dong? This thing belongs to the drama queen and has nothing to do with me!"

Liu Xie wasn't angry because of this, he was just a little offended. What's more, he was still thinking about winning over Xi Yu!

He had already started building this floor heating when he heard that he would be the prisoner.

By then there will naturally be some in the Han Palace.

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

After all, Liu Xie himself didn't care. If he was fussing over everything, that would be different.

Because Liu Xie was present, it happened to be almost noon, which was the time to eat.

If Liu Xie doesn't leave, naturally the courtiers have no intention of leaving.

"When I first came to Xuchang, I heard in Yanzhou that Xi Qing was good at cooking delicious food. I heard that Xi Qing was the one who spread the news about braised pork."

"Today, I say I won't be able to taste the delicacies at your house. I hope you don't mind!"

Liu Xie blatantly wanted to stay and enjoy the meal, but it was hard for Xi Yu to drive him away.

Cao Cao and others followed and planned to stay, as did Yang Biao and others.

Xi Yu curled his lips and glanced at everyone.

"It's okay if Your Majesty wants to stay. It's just a matter of adding one or two pairs of chopsticks to the family!"

"It's just that I don't have many chopsticks at home. I'm afraid I won't be able to entertain the Taiwei and others!"

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

It's your job to take advantage of others, but I don't care about these people, just figure it out!

Liu Xie was stunned for a moment, but he didn't expect Xi Yu to say such a thing, and Cao Cao was not surprised at all.

"Who is that? Dian Wei, go outside and tell Xu Chu that I am staying at the theater house to eat today, and ask Xu Chang to help bring more things!"

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

"Fengyi, Wen Ruo and the others can just handle it ourselves, you don't have to worry about it!"

As soon as Cao Cao said this, the only ones left were Yang Biao and others.

When Liu Xie heard what Cao Cao said, he also looked at Yang Biao and others: "Lieutenant, what Xi Qing said is not unreasonable. Sikong can solve it by himself. You can solve it by yourself later!"

Liu Xie meant that he didn't care about Yang Biao and others.

Logically speaking, if the host does not entertain guests, there is no reason for the guests to stay.

However, the situation today is different.

Liu Xie is staying, and Yang Biao and others are naturally unwilling to leave like this. Who knows what will happen after they leave!

"Hmph, is this how the dignified farmer treats his visitors?"

Yang Biao snorted coldly.

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

"What the Lieutenant said is wrong, I didn't hear that Da Sinong invited the Lieutenant to be a guest!"

"Wait, isn't it possible that you came here uninvited?"

As soon as Cao Cao spoke these words, Yang Biao's face turned a little dark.

Immediately afterwards, someone on the opposite side shouted again.

"What lieutenant? Is it difficult that you can't even afford food?"

These words were a bit harsh, and even Yang Biao almost couldn't sit still. If Dong Cheng hadn't pulled him by the side, Yang Biao would have been able to walk away at this moment.

Yang Biao suppressed his anger. Next to him, Dong Cheng had already given instructions to the officials beside him. Not long after, someone brought a set of eating utensils over.

At this time, Yang Biao looked at Cao Cao, spoke but couldn't help but speak.

"I heard that Sikong has helped His Majesty select the palace guards some time ago. Is this true?"

Yang Biao's words meant something.

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

At this moment, Yang Biao's words clearly meant that he was accusing Cao Cao of being a Sikong, acting on behalf of others, and not paying attention to the emperor.

Even if the Qianwei Lieutenant died while escorting the Emperor, it stands to reason that it would not be Cao Cao's turn to intervene now.

He was a great lieutenant of the Han Dynasty, and now he was the first among the Three Dukes. Cao Cao, who was also a Three Dukes, was not higher than him in terms of status.
