Hahaha, I'm smart, I know, but you can't say that, people will think that our master and apprentice are boasting. ”

Zhang Yuan didn't expect his student to be so straightforward, and directly told his advantages, fortunately, there was no one else around, otherwise it would be really embarrassing.

A few drops of sweat oozed from Yan Yi's forehead in the winter, and he also didn't expect Zhang Yuan to admit it directly.

Is it difficult to be an official but to be shameless?

Seeing that Yan Yi stopped talking, Zhang Yuan didn't want to continue to ridicule, so he changed the topic and said.

"You wondered why I was making a charcoal fire and then leaving the doors and windows open?"

Yan Yi subconsciously wanted to shake his head, he was afraid that this was another pit for Zhang Yuan, but after thinking about it, he really wanted to know and nodded heavily.

"Ask the teacher to solve the students' doubts."

"Look at the smoke from this charcoal fire, if I say that this smoke is poisonous, do you believe it?"

The brazier is almost a meter square, and the charcoal inside burns and you can clearly see the gray smoke.

Yan Yi looked at it and opened his mouth to say.

"Students believe."

"This smoke contains a lot of toxic substances, one of which is carbon dioxide, and if we inhale too much, it will lead to death.

I can only open the doors and windows, ventilate everywhere, and then you and I sit next to the charcoal fire, although it is colder, but it will not be poisoned. ”

Zhang Yuan deliberately said these terms, in order to cover Yan Yi, this kid has been a little impetuous recently, so that he understands that a mountain is more than a mountain is the real truth.

"Students don't understand what carbon dioxide is."

"There are many things you don't understand, for example, our bodies are actually no different from the bar, at most, there is a lot more water and other things, and you don't understand it.

Let's take a good look in the future, there are not only Confucian classics to read in this world, but also other things to learn.

I asked you to learn some about agriculture and mulberry earlier, what do you know? ”

Yan Yi was stunned, his brain was a little confused, and he didn't hear Zhang Yuan ask him about things.

"Teacher, what did you just ask?"

"I asked you what you learned about farming before?"

"Well, I think every grain of grain is hard-won, and we should cherish it."

"Poof."

Zhang Yuan had nothing to say, sure enough, those who studied scriptures were all engaged in thought, and it was really a wrong move at the beginning, which made Yan Yi go to farming.

Now it seems that Sima Qian's farming is much stronger than Yan Yi's farming.

"Isn't what the student said right?"

Yan Yi was very flustered, not understanding what he had said wrong.

"No, no, no, yes, yes, yes.

In the winter, there is no need to farm, and in the future, I will follow King Wuqiu Shou and Mei Gao to deal with some official affairs of Taixue and Du County. ”

"The student thanked the teacher."

Yan Yi was very excited, after all, his purpose was to become an official, studying the Five Classics was only secondary, and being an official was more important than anything else.

"Something happened to Taixue Ling, something big happened!"

A shout suddenly came from outside the door at this time, Zhang Yuan was shocked, didn't he sit here unharmed, could it be that Liu Che sent someone to arrest him, and he hadn't done anything recently.

Just as he was thinking about it, a man ran in panting, and even the usual rules were gone, and it looked like something really big had happened.

"Something happened to the Taixue Order."

"What's wrong with me?"

"It's not you who have an accident, it's Dr. Hu Wusheng."

"Hu Wusheng? What happened to him? Didn't this old man wander around some time ago? ”

"Dr. Hu Wusheng, his family just sent someone to send a message, saying that when the servant of the family went to knock on the door in the morning, he found that the person had lost his breath, and he should have left in the middle of the night last night."

Really dead?

These three words popped out of Zhang Yuan's heart, but he didn't feel any joy.

Death is great, and since death and departure, those grievances and grievances should also be dispersed with the wind.

"You lead the way, and I'll follow you to Hu Wusheng's mansion.

Yan Yi, you go and inform King Wuqiu Shou and Kong Anguo and others, we have to pay attention to this matter. ”

"Whoa."

Zhang Yuan put on a fur cloak and followed the official in Taixue to Hu Wusheng's mansion.

This place is already full of crying and crying sounds, Hu Wusheng and his family are not a lot of people, they are all over seventy, it is normal for men to have children in this era, their ancestors and grandchildren are four generations in the same house, and the family adds up to almost fifty people.

In addition, more than 100 students are now gathered in front of Hu Wusheng's room.

When everyone saw Zhang Yuan coming, they avoided it and made way for Zhang Yuan to enter the room.

"Too much of a school order."

"Too much of a school order."

Hu Wusheng's family members saw Zhang Yuan and greeted each other, and Zhang Yuan also returned the salute one by one.

They were worried that the previous grievances would make Zhang Yuan take revenge on a large family and deliberately make a concession.

Zhang Yuan's gladly accepting it also reassured everyone's hearts.

"Dr. Hu Wusheng went there last night?"

Zhang Yuan asked everyone in the room.

At this time, a man with gray hair stood up, Zhang Yuan remembered him, it seemed that he was Hu Wusheng's eldest son, and he was almost sixty years old.

"Returning to the Taixue Order, Jia Yan died last night."

Zhang Yuan looked around and saw a charcoal fire in the middle of the house, frowned and continued to ask.

"This pot of charcoal was placed here last night before Dr. Hu Wusheng went to sleep?"

The man nodded in astonishment, not knowing what Zhang Yuan meant by asking this sentence.

Guanzhong is very cold in winter, and ordinary people can't afford charcoal fires, that is, only officials and rich people can afford to use it.

For twelve hours a day, the charcoal fire is burned all the time, and the richer live in a warm house.

The floor heating of the descendants has been in Dahan, at least Zhang Yuan has seen it more than once or twice.

Liu Che uses a hollow copper pillar, which is usually a load-bearing column, and in winter, he adds carbon fire to burn it, and the thermal conductivity of the copper pillar is very good, and the smoke cannot be worn out.

In this way, the whole hall is warm.

Hu Wusheng's body was still lying on the bed, Zhang Yuan saw that his face was blue, and he felt that even if it was not the main reason, there were some reasons.

"Since Dr. Hu Wusheng has left and I am a scholar of Taixue, I will write a chapter to point out the doctor's merits before his death, and do my last thing for the doctor."

As soon as the words fell, the voices of gratitude were endless.

What high funeral specifications can a 600-stone doctor use, if there is no Zhang Yuan, it is estimated that he can only be buried hastily.

If there is Zhang Yuan's support in the back, maybe there will be a chance to be buried in Yanglingyi.

Zhang Yuan knew what they were thinking, so he promised to do his best, but in the end, it was estimated that there was little hope.

Even if Zhang Yuan hangs up by himself now, he may not be able to be buried in Maolingyi.
