Li Huaiyun put his hand on Xu Kun's shoulder, "No way! How could I let go of Brother Kun! You are the love of my life!"

Xu Kun looked at him in surprise, with goosebumps all over his body, "There's something wrong with you!"

"You're worrying too much, Brother Kun! Even if I want to leave, Captain Yuan won't agree to it! If I really leave, I have to fight to the death with me."

"That's true! Why did the Muyuan helmsman ask you to impart knowledge?..."

"Just a little knowledge about mechanics!"

"Do you still understand this?" Xu Kun was a little confused. When he entered the Demon Slayer Division, he knew the basic situation of this person. When did he acquire mechanical knowledge?

When he saw that Mu Yuan had walked out of Liuyuntang, he immediately said, "We'll talk about it later. You hurry over!"

"yes sir!"

Xu Kun looked puzzled, "What? What the fuck?"

Li Huaiyun smiled and waved, then ran outside and caught up with Mu Yuan who was walking towards Qianji Pavilion.

"What does the helmsman want from me?"

Mu Yuan tilted her head, "You must have not started writing last night, right?"

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

"Don't worry! I will definitely do what I promised the helmsman!"

"Don't be in a hurry about mechanics theory!"

Ah! No hurry, then what are you asking?

"I came to see you because I need help with something!"

Seeing that Mu Yuan didn't urge him to write anything, Li Huaiyun patted his chest happily and said, "No problem."

"Why don't you ask?"

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

Mu Yuan glanced at him and snorted, "You are quite good at talking. In this case, you can lend me all your salary for this month first."

"Ah!" Li Huaiyun looked confused. He never expected that he was actually borrowing money!

Whenever money is involved, conflicts are easy to arise.

Besides, in his mind, Mu Yuan is the helmsman, and his salary is much higher than his, so he still needs to borrow money from him?

He is very sensitive about money now. After all, he spent a lot of money in jail and his family almost had no food to eat.

"What? Aren't you trying your best?"

Li Huaiyun was silent for a moment, "I tried my best, but the last time I was imprisoned, my family had a lot of money just to manage, and even food was a problem. If I borrow the money again, wouldn't I starve to death!"

Mu Yuan snorted, "Don't worry, I was just talking casually, I know you can only say beautiful things."

"That's what the helmsman criticized!"

"I came to you today to ask you to explain the theory of mechanics. I asked everyone from Qianji Pavilion to come to the courtyard."

"What?" Li Huaiyun curled his lips, good guy, kill first and then show off, right?

I'm not ready yet! I'm about to go on stage to give a speech. This is not about rushing a duck to the top!

Just as he was about to speak, Mu Yuan glared at him, "Now, I don't want to hear you say no!"

Li Huaiyun immediately explained, "I'm very happy that the helmsman invited me over, but the incident happened suddenly and I was a little unprepared.

If you want to explain it, you need to make some preparations, otherwise it will be confusing."

Mu Yuan didn't want to accept this explanation, "I'm not asking you to explain in detail. Is it very demanding for you to explain the most basic knowledge?"

"It's not that high, but the most basic things require some understanding of mechanics."

"Then you start from the bottom!"

That would take a long time, and just dictating it there would not be enough.

Li Huaiyun glanced at Mu Yuan, the woman looked like she would let him go.

He couldn't escape today's class. In this case, he might as well accept the invitation openly.

"Okay! Then I will briefly explain some theoretical basis and hope you can understand the content."

When Mu Yuan heard this, a smile broke out on her face, which was obviously more beautiful and attractive than her who usually kept a straight face.

She is quite looking forward to this aspect. On the one hand, this mechanical theory will be of great help to her future productions. On the other hand, Li Huaiyun is a bit slow and has to wait for two weeks, which makes it difficult for her to wait.

Mu Yuan brought Li Huaiyun to Qianji Pavilion.

In an open space in the courtyard, hundreds of people were meditating on the ground. The faces of these people all had looks of expectation. After all, the so-called mechanical theory, in their view, was simply a new technology from this foreign land.

Li Huaiyun stood in front of the hundred people. He looked down, feeling a little nervous. He looked back again and found that there was no space behind him. There was no atmosphere like giving a lecture at all. He just talked like this, which was time-consuming and laborious. He also said

Not sure.

Moreover, mechanics does not have corresponding drawings to explain, and it is even more confusing to just talk about it without any basis.

So he pulled Mu Yuan aside, talked about some things, and asked her to arrange a few people to prepare some things.

"So troublesome?"

"No trouble, if you want to explain clearly, you have to do this!"

Mu Yuan complained a few words, but honestly did as he said.

After a while, someone brought two bamboo poles, a large piece of white cloth and a writing brush. According to Li Huaiyun's instructions, those people made a simple cloth blackboard.

He explained to Mu Yuan and the other people sitting, "When I explain the theory of mechanics, I will use these to draw pictures, otherwise it will be difficult for you to imagine based on what I say."

Mu Yuan looked at the cloth blackboard set up and nodded in agreement.

This time, she was a little surprised. This person's mind was spinning so fast, and he suddenly thought of using this method as a tool to explain drawing.

It would be a pity that this guy doesn't join Qianji Pavilion.

Li Huaiyun stood in front of the cloth blackboard and looked at the hundreds of people sitting below, his heart beating slightly. He had never lectured in front of so many people.

"Force! It is generated by the mutual interaction of matter in this universe, whether it is as large as various planets, or as small as something invisible to human eyes, it will always exist."

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

Faced with this novel knowledge, coupled with common sense in life, everyone else present looked suddenly enlightened, and showed a strong interest in it, wanting to understand the mysteries of this knowledge.

Just when Li Huaiyun was explaining scientific knowledge in front of the blackboard, Qin Gang and the Seventh Prince happened to arrive at Qianji Pavilion. They heard the sound coming from outside and walked inside curiously.

Hundreds of people were sitting on the ground, all listening to Li Huaiyun's explanation attentively. This scene really surprised Qin Gang, because this kind of situation can only happen to those saints and great Confucians. The appeal they have can make people quiet.

I sat there and listened patiently.

Qin Gang was surprised when he also discovered the homemade blackboard behind Li Huaiyun. "Oh, who came up with this? Put a piece of cloth behind you to draw, so that people can understand it easier!"

"Wonderful!"

The Seventh Prince was also curious about this new thing, "This man has great ideas!" He pinched his chin, maybe I can do the same next time.

They entered the courtyard, followed by many guards, who also entered the courtyard, making the courtyard suddenly appear full.

However, the people sitting on the ground were indifferent to this huge scene.

While Li Huaiyun was explaining, he suddenly saw a group of people coming in at the courtyard gate. One of the people walking in front was Sikyong, but he didn't know the other person very well. Judging from his appearance and dress, he should be

Someone with a certain status...

Why is Sikyong here? Who is that person next to him?

He now seems to be inspected by the leader for a work report!

"What you're talking about sounds quite profound!" Qin Gang stroked his beard.

"Sikyong!" The seventh prince said to Qin Gang, "Do you understand what this man is saying? I can't understand it at all."

Qin Gang responded, "I understand a little bit! However, that knowledge is of little use to us. Where did this guy learn this knowledge?"

"I didn't understand half of the sentence! However, the steady and steady manner this person showed when he was giving lectures is really admirable."

"These truths are actually profound and simple. As long as the Seventh Prince knows the most basics, he can understand what this person is saying!"

"This person is what you call a bad person!"

"Ah! It's him!"

Li Huaiyun talked for about half an hour. He explained the three laws of mechanics using simple and easy-to-understand knowledge. Then he drew an analysis diagram on the cloth and wrote annotations.

"So, everyone probably understands?"

Most of the people sitting below nodded, but a small number of others still didn't understand. He proposed to let those who understood explain it to those who didn't understand.

Li Huaiyun stood there and breathed heavily. To be honest, he was not prepared. The limit of what he could handle was already the limit.

Mu Yuan walked up and patted his shoulder, "Very good! It's very well said. I understand it, but I still need some time to digest it."

"Thank you for the compliment, helmsman. If you still don't understand anything in the future, you can come to me alone and I will explain it to you."

"OK!"
