Although many things have been finalized, the next thing is to execute, Zhu Yuan is still busy until the time of the hour before returning to the inner house.

I took a comfortable hot bath, changed my clothes, went to the study on the west side of the main house, and opened a codex.

This is a part of Liu Laoqi's meteorological observation experience notes recorded by Liu Lian's scribes in recent days according to Zhu Yuan's request.

Zhu Yuan's request is to explore the 'why' behind 'its nature'.

Liu Laoqi's premonition of the weather is simply magical, and if he is lucky, he may even be reincarnated as a god and worshipped.

However, Zhu Yuan understands that behind everything, there is a scientific truth. Even if there are some things that cannot be explained by existing science, it is only the limitation of human knowledge, and it is not unreasonable.

Just like the moment, Zhu Yuan soon discovered one thing.

Liu Laoqi can quite keenly feel the changes in the qi of heaven and earth around him, whether it is rich or thin, 'the qi of heaven and earth', this is the word recorded by the scribe in the notes, but Zhu Yuan can see through the essence at a glance.

It's 'air pressure'.

In fact, ordinary people can also perceive it in their daily lives, such as 'autumn is high and cool', such as 'summer is hot', behind these words, are the external feelings brought by changes in air pressure to human beings.

What makes Liu Laoqi special is that he can not only feel the changes in air pressure more keenly, but also infer what kind of meteorological changes these changes will bring.

In addition, according to the notes that have been recorded, Liu Laoqi's special is not only a keen perception of air pressure changes, to be precise, this is a comprehensive instinct to predict weather changes formed by the old man's innate keen perception of the surrounding environment.

It has to be said that it cannot be reproduced.

However, Zhu Yuan still quickly decided to list 'air pressure' as a course he would teach in the near future.

The Maritime Academy has started quickly in the past two days, and the location is in the Dinghai County Ya near Zhu Yuan's mansion, and Xue Shu took the initiative to provide the venue, because it is also an important town, the Dinghai County Ya built in the Yuan Dynasty is very spacious, and several of the halls can be used for classes.

This is also temporary.

Zhu Yuan joked with Shen Mao in the afternoon about the addition and repair of the Dinghai City Wall, not casually.

Since it will become an important port town in the future of the Ming Dynasty, the current county town of Dinghai is really a little small in Zhu Yuan's opinion. Not to mention the city wall, Zhu Yuan is really not interested in this thing, but in the formal maritime academy, Zhu Yuan plans to divide a large piece of land outside the city, and when the maritime merchants hand over the money, they will start building as soon as possible.

This was the first step in the expansion of the city.

At the same time as the Maritime Academy opened, the mini-school in the Yinghai Envoy's Mansion also continued.

Just like tomorrow, the theme that Zhu Yuan intends to talk about is 'mechanics'.

Of course, it is not the later mechanics, the proposition is too big, and it is still a variety of mechanical applications related to the transportation of grain at sea in the near future, such as wind, buoyancy, friction, such as the lever principle involved in the construction of a large gantry crane on the bank of the Yongjiang River in the west of the city, and so on.

The 'air pressure' that suddenly comes to mind will take several days to be discharged.

I also took the time to think about my memories and prepare my teaching materials and props.

When Qing Niang walked over cautiously with a teapot like a cat, Zhu Yuan had already brainstormed and quickly wrote down several pages of air pressure correlation.

Just in time for a break.

Leaned on the chair surrounded by thick cushions and stretched her body, and waited for the warm lady who followed the young lady to put down the cup, and the young lady poured the tea at the right temperature and brought it up.

Zhu Yuan took it, just took a sip, and suddenly noticed that there was an extra ...... on the young lady's head The awl, his eyes widened suddenly, and a sip of tea squirted out directly, and choked into his nose.

Poof-

Ahem, ahem!

There was a lot of chaos.

Not only the green lady, but also the freehand, blank and Luoshui who were originally around the round table next to them or embroidery or drawing, also hurriedly got up and came around, smooth and smooth, wiped and wiped, and rescued the draft of the rescue.

Waiting for Zhu Yuan to come over, the unforgiving blank finally spoke, glared at Qingniang and said: "A mouthful of water can choke a little official, you are really a great skill." ”

After speaking, he glared fiercely at Nuan Niang, who had just subconsciously hid to the side and did not move.

But he didn't speak.

Seeing that the young lady had begun to shed tears, Zhu Yuan waved her hand, exhaled slowly, and finally pointed to the 'awl' on the top of a woman's head: "This ...... What is it? ”

Standing on the other side of his own petty official, he stared blankly, didn't let her say more, continued to caress the back of his petty official, leaned over a little, and said softly: "Little official, this is a bun, I just sent it today, one of my sister's heads, but it's not complete, some beads and steps are still doing." ”

Zhu Yuan remembered.

After that birthday, I quietly talked to myself about whether I wanted to give Qing Niang a pair of head jewelry. Zhu Yuan understood at the time that this was a kind of statement, and it could even be said to be a ritual, which was very important to women, so he naturally agreed.

That's it......

This...... Awl, Zhu Yuan really can't be aesthetically paught.

However, seeing that the young lady was still crying, she understood that this stupid woman was hit the first time she showed her head in front of him, and she might want to do more, so she could only comfort: "Okay, okay, don't cry." This one...... It's mainly a country kid like me, I haven't seen you city people dressed up, fuss, I was wrong, don't cry. ”

When Qing Niang heard that her petty official had confessed her mistake to herself, she immediately shook her head quickly, wanting to speak, but she sobbed even more, and could only cover her mouth with a handkerchief.

Zhu Yuan simply motioned to Luo Shui: "You take her back to the house slowly." Well...... Take off this awl too," he said and was afraid that Qingniang would be frightened, so he pulled her hand and pinched it, and said bluntly: "I admit that you are my concubine, but this awl has nothing to do with you, that's it...... It's too ugly for me to accept. Wait a minute, I'll personally help my good young lady design a better headdress, okay? Go ahead and wash your face. ”

When Zhu Yuan said this, Qingniang finally stopped crying, nodded, and was helped by Luo Shui to leave the main house.

Waiting for the young lady to leave, Zhu Yuan checked the various drafts in front of him just now, fortunately, there was not much water before, and the manuscript was fine, but he was choked uncomfortably.

Freehand took another robe to wear in the house, Zhu Yuan changed it, sat down next to the bookcase again, took a cup of tea that was sent over by the blank more carefully, and finally looked at the woman who was still standing next to her silently: "Since you are reluctant to stay here, forget it." Do you still have relatives, and I'll have someone send you away tomorrow? ”

Nuan Niang paused, only then confirmed that the little master was talking to herself, and was stunned again, hesitated for a short time, and then shook her head, her voice was still very soft and low: "Concubine...... Slave family, there is nowhere to go. ”

After saying that, he finally realized something, knelt down softly, hung his head, and waited for the appearance of the hair.

Seeing this, the blank man standing next to his own petty official pouted again, and wanted to say that it was easy to do it if he had nowhere to go, and he could sell it for a few dollars.

However, even if you think so, it's not stupid to leave blank, and you won't say it in front of your own petty officials.

Zhu Yuan felt the warm heat of the porcelain cup in his hand, looked at the woman, and said: "I suddenly found that the name I gave you before was wrong, Weiyang, not 'unfinished', Yang is 'exhausted', give you another chance, choose for yourself, Shen Nuanwei, or Shen Nuanyang?" ”

Nuan Niang hesitated, and suddenly thought of the tone of the little master who had just coaxed a child to talk to Qing Niang, and then thought about these days, although the first night of that day let her sleep outside and be frightened all night, she listened to it...... But, perhaps, this is already the best place for her to live for the rest of her life.

It's just that......

After a moment of silence again, Nuan Niang finally spoke again, still in a very soft and low whisper: "Slave...... Choose 'Nuanwei', Shen Nuanwei. ”

Zhu Yuan nodded: "Get up, go and rest, change your appearance tomorrow, don't be so cold again." ”

Nuan Niang stopped again, and her voice seemed to be louder: "Yes." ”
