For Lyon, Ada and others, it is strange that it is a world with martial arts; for Zhang Jing, Murong Jiu and others, it is strange that it is a world without martial arts. The so-called "background difference" is just like that. Not everyone is born like Leeds with a diverse worldview.

Because of the "strangeness" of this world, the cousin who suddenly saw the superficial external skills and the warriors who were doing very miserably touched some. It was obvious that other people's world had nothing to do with them, and they were surrounded by "martial arts" all their lives still couldn't help but associate... But please rest assured, they quickly adjusted their mood. That afternoon, they ran to find their husbands shopping with other women, and asked him why they didn't come to comfort themselves.

How Leeds fooled them and skipped it. In short, everything returned to the previous rhythm of "visiting and traveling", and at most it was to use "Baozhilin" as a hotel.

However, defeating Huang Feihong in front of everyone in "Baozhilin" still makes their stay-at-home life change... Don't worry, on the one hand, Huang Feihong is well-disciplined, and on the other hand, Zhang Jing did not show off his power in this battle, and the disciples did not resent Leeds and others for this, which is a change in the better direction.

For example, the disciples led by Liang Kuan always show their presence in front of Zhang Jing, wanting to show their good feelings and teach a move. Zhang Jing, who was annoyed, finally asked his cousin who was well-informed and remembered to write "Hunyuan Gong", "Divine Movement", and "Hunyuan Palm", and threw it directly to Huang Feihong, the master. The same old saying, cultivation requires time to accumulate, even if you are a peerless genius. Unless someone passes his lifelong skills to Huang Feihong, the strength of his and his disciples will not increase at all until Leeds finishes his journey...Well, Zhang Jing is not great to this extent.

For example, Huang Feihong respectfully asked Murong Jiu for medical questions. The only thing that can be called "superior medical skills" is only about trauma. He is not a "miracle doctor" who specializes in treating strange and complicated diseases. Although Murong Jiu's medical skills are not as good as Wan Chunliu. Ping Yizhi, Xue Muhua, Cheng Lingsu and other miraculous doctors in the martial arts world are powerful, he is still a master at least. He can't help but mock the various drugs prepared by Huang Feihong. Only when Master Huang has a good temper can he realize that this girl has real talent and knowledge. In fact, Murong Jiu herself is also very happy~~ When he has broken hands and feet, he can treat it by eating food to recover blood through the mc system. Medical skills are useful, and she finally found an opportunity to show her skills!

For example, Aunt Thirteen taught Wang Yuanji, who was diligent and studious, and took her to a bookstore to buy textbooks. Aunt Thirteen, who had just returned from London, had nothing to do. Her current situation was completely aimed at the hostess of "Baozhilin". She was so idle that she wanted to teach advanced foreign culture but no one was willing to learn it. The whole "Baozhilin" was Huang Feihong, and Yass Su were not reckless. She found that the student Seedlings naturally did her best. Well, Leeds did not teach girls too detailed and scientific, but it would not stop Wang Yuanji from studying. Some things were the master who reached out to push the door open. It was better to see the girls' own wishes.

——Obviously, the relationship between Leeds and the people of "Baozhilin" has become very good.

However, this relationship can only last for three or five days. The stay is just a "stay", and the guests can only be a "guest". It is almost time to end.

The most important marker of the end is right before our eyes - the invention of the "steam engine" at the beginning of the Industrial Revolution.

"...Is it this huge metal lump?" Murong Jiu wouldn't say that she was secretly shocked. This was the largest metal lump she had seen in her life.

"I thought it was the same size as a TV..." Zhang Jing did not hide it at all. She forgot the pain when the injury healed, and forgot the annoyance when Leeds teased her.

"To be honest, it's the first time I've seen a real thing..." No matter how much I run around in "Biochemical World", I will never find a place where I'm still using a steam engine. "However, it's normal for the production equipment in the factory to have this size."

Leeds and others were visiting the workshop of a foreign-funded factory in Foshan... How did they come in? It was mainly due to the credit of the ocean (silver dollars), but I have to say that if it weren't for Leeds' Western face, the foreign boss would never let outsiders in no matter what, for fear that the Qing people would make trouble for themselves! It seems that not only the Qing people regard Leeds as part of foreign invaders, but even the Western people regard Leeds as their own, and Leeds did not know whether they should be happy or worried.

"This thing... can be a substitute for human power?" Wang Yuanji looked at Leeds and sought answers.

Her knowledge at this time would not allow herself to instantly understand the working principle of this thing.

"Well, it's a bit troublesome to explain this... I don't know if you can understand it." Leeds turned around, and Sakiya had already taken out a piece of cardboard with patterns on it.

"First of all, do you understand what this is?" Leeds asked pointing to the cardboard.

"I know, isn't this the internal structure of the castle's clock tower? It has nothing to do with the steam engine." Although Leeds was just a schematic diagram, Zhang Jing recognized it just after a glance.

"It doesn't matter, but what I want to say is," Leeds pointed his finger at the transmission gear on the cardboard. "When these metals form a unique shape, they can play a role above the 'metal', generally called 'parts'."

"…!" It was not difficult for the three of them to figure out this out.

"Then," Sakiya had silently changed into a painting without Leeds' instructions, "This is the rough working structure diagram of the core parts of the steam engine."

"……………” The three of them fell into a long silence and watched carefully... they didn't understand.

This is also normal. It is like letting a senior high school student open the textbooks of a senior high school student casually. He just reads a picture and understands everything. Then why do teachers do it? It is appropriate for students to not understand.

"Put the fuel to boil water in the boiler, and the steam enters the cylinder from the pipe," What is a boiler, what is a pipe, and what is a cylinder, it is too troublesome to explain it. Just use your hand to indicate the position on the diagram. "Then the steam pushes the piston up and down and back and forth, go up and down, the frequency is quite stable, and the strength of the steam can be increased at will. It is easy to exceed the strength of humans. In this way, you can use it to complete certain processes... After saying so much, you don't even understand the reciprocating movement, right?"

The three nodded, and it was easy to understand how the problem was possible.

"This is why I explain the parts of the clock tower first," Leeds sighed and signaled Sakuya to put away the drawing board. "No matter what, I can't draw the whole set of parts. Tell you that 'after the combination of unique shapes', the function of reciprocating movement is the limit. The rest... either ignore it, or look for textbooks in the future, or you can't pry the steam engine to see. I promised that the boss would not make trouble."

"Tsk~ we are not interested in this." Zhang Jing said dissatisfied... Well, she was not afraid of causing trouble, she just felt that she couldn't understand even if she dismantled the steam engine.

The appearance of this huge metal composition is complex enough!

"I think you're more interested~~" Leeds looked up at the huge steam engine.
