Li Huaiyun stretched out his hand and put it on Xu Kun's shoulder, "How can there be!" How can I give up Brother Kun! You are the love of my life! ”

Xu Kun looked at him with surprised eyes, goosebumps all over his body, "Something is not quite right with you!" ”

"You're too worried, Brother Kun! I just want to leave, and this Yuan Helm Lord won't agree! If you really go, you have to fight with me. ”

"That's right! This wooden kite helmsman has asked you to impart knowledge, what's going on?。。。 ”

"It's just a little bit of mechanical knowledge!"

"You still know this?" Xu Kun was a little puzzled, when he entered the Demon Slaying Division, he knew the basic situation of this person, when would he have mechanical knowledge?

He saw that the wooden kite had already walked out of the Liuyun Hall, and immediately said, "Later, you hurry over!" ”

“YES SIR！”

Xu Kun looked puzzled, "What?" What's the Daddy? ”

Li Huaiyun smiled and waved his hand, then ran outside wildly and caught up with the wooden kite that was walking towards the Thousand Machine Pavilion.

"What is the helmsman looking for me?"

The wooden kite tilted her head, "You must not have written last night, right?" ”

Li Huaiyun explained helplessly, "I'm sorry, helmsman, after all, I was investigating the case in Xiakou Town, and I only returned to Kyoto in the morning, and I was a little sick!" ”

"Don't worry! I promised the helmsman that I would do it! ”

"There is no rush in the theory of mechanics!"

Yes! Don't worry, then what do you ask?

"I'm looking for you for something I need help with!"

Li Huaiyun saw that Mu Kite didn't urge him to write, so he patted his chest happily, "No problem." ”

"Don't you ask what's going on?"

Li Huaiyun said sincerely, "No matter what, my subordinates will do their best." ”

The wooden kite glanced at him and snorted, "You kid is quite good at talking, since this is the case, then you can lend me all this month's money first." ”

"Ahh Li Huaiyun's face was embarrassed, he never thought that he was actually borrowing money!

As long as money is involved, it is easy to conflict.

Besides, in his heart, this wooden kite is the helmsman, and he doesn't know how much higher than him, so he still needs to borrow it from him?

He is now quite sensitive to money, after all, he spent a lot of money in prison, and his family almost had nothing to eat.

"What? Isn't it all you can? ”

Li Huaiyun was silent for a moment, "I did my best, but the last time I was in prison, just by doing a little, there was a lot of money at home, and even eating became a problem, and if I lent the money out, wouldn't I starve to death!" ”

Wood Kite snorted, "Don't worry, I'm just talking casually, and I know that you can only say pretty things." ”

"What the helmsman criticizes!"

"I came to you today to let you explain the theory of mechanics, and I asked the people of Qianji Pavilion to come to the courtyard."

"What?" Li Huaiyun pouted, good guy, cut first and then play, right!

I'm not ready yet! It's about to give a speech on stage, it's not about catching ducks on the shelves!

As soon as he wanted to speak, he was glared at by the wooden kite, "Now, I don't want to hear you say a word!" ”

Li Huaiyun immediately explained, "I'm glad that the helmsman could invite me over, but it happened suddenly, and my preparation was a little insufficient.

If you want to explain, you need to be prepared, otherwise it will be foggy. ”

The wooden kite didn't want to accept this explanation, "I didn't ask you to explain it in detail, you explained the most basic knowledge, is this very demanding?" ”

"It's not high, but the most basic thing requires some understanding of mechanics."

"Then you start at the bottom!"

That's a long time, and it's not enough to just dictate there.

Li Huaiyun glanced at the wooden kite, and this woman looked like she would let him go.

In today's class, he can't escape, since this is the case, it is better to accept the invitation generously.

"Okay! Then I will briefly talk about some theoretical foundations, I hope you can understand the content. ”

When the wooden kite heard this, a smile bloomed on her face, which was obviously more beautiful and attractive than her, who often had a straight face.

She is quite looking forward to this, on the one hand, this mechanical theory will be of great help to her future production, and on the other hand, Li Huaiyun is a little grinding, and she has to wait for two weeks, which is really difficult for her to wait.

The wooden kite took Li Huaiyun to the Thousand Machines Pavilion.

In a clearing in the courtyard, hundreds of people meditated on the ground, and their faces were all looking expectant, after all, the so-called theory of mechanics, in their opinion, was simply a new technology from this exotic land.

Li Huaiyun stood in front of the hundred-digit people, he looked down, a little nervous, and then looked back, and found that there was no atmosphere behind him to give a lecture on the stage, so it was time-consuming and laborious, and it was not clear to say.

Besides, there is no corresponding drawing explanation for mechanics, and just talking there is no basis, which is even more confusing.

So he pulled the kite aside, said something, and asked her to arrange for a few people to prepare something.

"So troublesome?"

"It's not troublesome, if you want to make it clear, you have to do it!"

The wooden kite complained twice, but still did what he said honestly.

After a while, someone brought two bamboo poles, as well as a large white cloth and brush, and according to Li Huaiyun's instructions, they made a simple cloth blackboard.

He explained to the kite, and the other seated people, "When I explain the theory of mechanics, borrow these drawings, otherwise it would be hard for you to imagine just by me." ”

The wooden kite looked at the blackboard of cloth and nodded approvingly.

This one made her a little surprised, this person's brain was spinning so fast, and all of a sudden, she thought of using this way as a tool to explain drawing.

It's a pity that this guy doesn't join the Thousand Machines Pavilion.

Li Huaiyun stood in front of the cloth blackboard, looking at the hundreds of people sitting below, his heart beat slightly quickly, he had never lectured in front of so many people.

"Force! The matter in this universe is produced by each other, whether it is as large as various planets or as small as something that cannot be seen by the human eye, it will exist. ”

Li Huaiyun simply drew a few figures on the cloth and then continued to explain the contents to them.

In the face of this novel knowledge, but also with the common sense of life, the other people present were suddenly enlightened, and showed a strong interest in it, eager to understand the mystery of this knowledge.

Just when Li Huaiyun was in front of the blackboard and came to explain scientific knowledge, Qin Gang and the Seventh Prince also happened to come to the Thousand Machines Pavilion, and when they were outside, they heard a voice coming from inside, so they walked inside curiously.

Hundreds of people sat on the ground, all listening carefully to Li Huaiyun's explanation, this scene made Qin Gang really surprised, because this situation can only appear in those saints and great Confucians, and the appeal they have can make people sit there quietly and listen patiently.

Qin Gang was surprised, but also found the homemade blackboard behind Li Huaiyun, "Hey, who came up with this, put a piece of cloth behind him, and use it to paint, which makes it easier for people to understand!" ”

"Wonderful!"

The Seventh Prince was also curious about this new thing, "This person has a lot of ideas! He pinched his chin and said maybe next time, I could do the same.

They walked into the courtyard, and the many guards they carried behind also entered the courtyard, which made the courtyard suddenly seem full.

It's just that the people sitting on the ground are indifferent to this huge scene.

When Li Huaiyun was also explaining, he suddenly saw the gate of the courtyard, and a group of people came in, one of them walking in front was the secretary, but he didn't know the other person very well, just from the appearance and dress, he should have a certain status.

How did the secretary come here? Who was the man next to him?

He now looks like he is being inspected by the leader!

"Something sounds quite profound!" Qin Gang stroked his beard.

"Si Zheng!" The Seventh Prince said to Qin Gang, "Do you understand what this person is saying?" I don't understand at all. ”

Qin Gang responded, "Understood!" However, that knowledge is of no use to us, where did this guy learn this knowledge. ”

"I didn't understand half of the sentence! However, when this person gave a lecture, he showed such a steady and solemn atmosphere, which is very admirable. ”

"These truths are actually simple to understand, as long as the Seventh Prince knows the most basic, he can understand what this person is saying!"

"This person is what you call infallible!"

"Ahh It's him! ”

Li Huaiyun spoke for about half an hour, he explained the three laws of mechanics with easy-to-understand knowledge, and then drew an analysis diagram on the cloth and wrote notes.

"So, do you all understand?"

Most of the people sitting below nodded, and the rest of the people still didn't quite understand, and he proposed to let those who understood explain it to those who didn't.

Li Huaiyun stood there, gasping heavily, to be honest, he was not prepared, and it was already the limit to be able to do so much.

The wooden kite walked up and patted him on the shoulder, "Good! It's very good, I understand it, but it will take some time to digest. ”

"Thank you for the praise, if there is anything you don't understand in the future, you can come to me alone, and my subordinates will explain it to you."

"Okay!"

The two of them began to ask questions about mechanics and continued to talk until someone stepped up to greet them.

"Fourteenth sister!"

Before, next to the secretary, the man in a gorgeous brocade dress and a talent came over and said hello to them.

The wooden kite turned his head, glanced behind him, and then shouted, "It turned out to be Brother Qi, what did you come to me for?" ”

Seventh brother? This guy has a lot of brothers!

"In a few days, there will be a celebration ceremony in the house, and the fourteenth sister remembers to come and participate."

The wooden kite had a sad face, she hated this kind of dinner ceremony, it was a complete waste of time, but this celebration ceremony was about to start.

"Can you not go?"

"Of course not!"

"It's really troublesome, let's talk about it then!"

Li Huaiyun stood aside and bowed lightly to Si Zheng, "I didn't expect Si Zheng to come here!" ”

"It's just boring, accompany this seventh son here and meet his fourteenth sister!"

This man is actually the helmsman's brother! I really didn't expect that it must be a relative of the emperor, Li Huaiyun hurriedly clasped his fists and saluted, "Seventh prince!" ”

"No need to be polite, I just heard you talk about that theory, it sounds quite profound!"

The wooden kite interjected, "It's just that you don't understand, it's actually not that difficult." ”

"What the fourteenth sister said is extremely true."

"If nothing happens!" The wooden kite's face was not very good-looking, "Don't be here, I need to go back and meditate on this theory of mechanics he said." ”

"I haven't seen you for so long, I want to go out for a walk with you, sister, and ask about it by the way

"Then since that's the case, don't bother!" The Seventh Prince nodded and followed Si Zheng out of this place.

Mu Kite looked at Li Huaiyun and waved his hand at him, "You! Don't go yet, come with me! ”

"Ahh What's the matter? Li Huaiyun was a little puzzled, his words were finished, "Helmsman, I have something to do, then I have to give it to you, saying that I want to return to Liuyun Hall first and wait!" ”
