I was about to say something, but Li Xue ran away with a smile.

As soon as she left, the helpless expression on my face disappeared without a trace.

I don't believe that my brother doesn't lie to his sister!

I'm so happy with the environment!

It's secluded, and no one botheres me, I'm basically the boss here, and I say it!

And I have a perfect place to sleep, okay!

After that, I had to get up at 7 a.m., leave at 7:30 a.m., and arrive at school by 8 a.m.

Is this a life that people can live?

How is it possible for a human to get up at 7 o'clock every day!

As long as I can avoid that talkative Joan of Arc, then I can basically make a day of waves!

Personally, I am very satisfied with this Rose Building.

But the first thing I need to solve right now is my stomach.

"Goo~~~"

If you're hungry, let's go eat first!

While the five mentally handicapped were still fighting, I casually asked someone where the small cafeteria was, and then I had a good meal, and then walked back to the Rose Building by myself.

Standing at the gate of the Rose Tower, I had the great dream of sleeping after eating, and pushed the door open with a slap.

"I'll go!?"

Well, I'll admit, I was stupid.

I'm a little too high to see this Rose Tower!

This Nima is definitely a dangerous building, okay!

As soon as I opened the door, I was so choked by the dust that I couldn't even open my eyes.

How many years has this building been unused?

In the dust, I vaguely saw a figure busy inside.

It's unlikely to be haunted in broad daylight, so I couldn't help but be curious, and walked in with my nose and mouth covered.

As a result, a surprised voice suddenly came from inside: "Ah, Lotte, you're here! Hurry up, it's just that there is a shortage of manpower here, you come to help!"

As soon as I heard this sound I knew it was broken!

"Why are you here?" I asked helplessly.

The owner of this voice is definitely Jeanne d'Arc.

I have a good memory, especially the impression of my future head of the department, the head teacher who is also the class teacher, so it is absolutely impossible for me to hear it wrong.

Sure enough, with a gust of wind howling, countless dust was blown out along the gate.

As soon as my vision was clear, I saw the smiling teacher Joan of Arc in front of me.

And just as I was about to run away, Joan of Arc's voice suddenly sounded: "Hey, come here, Lotte, can you figure this thing out?" ”

I......

If it weren't for the fact that I saw Joan of Arc using her spiritual power when she just removed the dust, I would have run away.

In order not to offend my future department head and class teacher, I had to walk up with a stiff brow.

As a result, I followed Joan of Arc's field of vision, blurted out, and said, "It's just a four-bar linkage device, what are you going to do, teacher?

After I finished speaking, I looked at Joan of Arc helplessly.

To be honest, the technological development in this world is really a bit deformed.

People can make tools, smelt steel, and make some small devices to help them work, but people in this world may take spiritual power too seriously, so the technology tree is completely at the level of the Song Dynasty in China.

Do you know how much headache I had when I first crossed over?

No smartphones, no tablets, no glory of kings, no exciting battlefields.......

Well, too much at once.

To sum up, the human beings in this world are mainly focused on developing their physical abilities, and the technology tree is actually just getting started.

But I have to say that the materials of this world are better than the world before me in all kinds of properties.

Therefore, a simple four-bar linkage device can't be disassembled by my Joan of Arc teacher.

Joan of Arc's eyes lit up when she heard what I said, and hurriedly said to me, "Oh! I thought this was some kind of spiritual weapon, no matter how I injected spiritual power, it wouldn't move." Lotte, do you know a lot about this, hurry up, do the teacher a favor, I don't know how to teach you if this doesn't move!"

Mom, can I drop out of school?

Teachers won't!

What do you think I'm doing to school?

I looked at Joan of Arc helplessly, then at the simple four-bar linkage.

There is nothing wrong with the device itself, but, teacher, don't you think it lacks a power source?

I said helplessly: "Teacher, you are optimistic." ”

With that, I held a pole in my hand and pulled it a little harder.

"Ahem, cough, cough ....."

Turning human power into power, the device really moves.

However, this ash is too big!

I was choked and almost didn't catch my breath, but it turned out that Joan of Arc used her spiritual power to disperse the ashes again.

Then I heard Joan of Arc's excited voice: "Oh, it's really moving! Lotte, you're amazing!"

Can I say that I was praised by my teacher and I was not proud at all?

It seems that this teacher is not only a bit of a talker, but also doesn't seem to have a bright brain!

I looked at the sun from the window, and now the sun was almost overhead, so ......

"Teacher, if you're okay, then I'll go to sleep!"

I was about to leave, but my sleeve was pulled at once, and I turned my head to see the hope on Jeanne d'Arc's face.

"It's just this move, I'll give you a lesson! Anyway, this building is just me and you, you can't find a place to sleep! Come on, come on, Lotte you come here." ”

With that, Joan of Arc didn't care whether I agreed or not, and dragged me to the device that the schoolboys knew.

"Wait!"

Joan of Arc let me go, ran to the side quickly, and came back with a book in hand, and I looked at the cover.

Basic Mechanical Knowledge.

No way!

You asked a Ph.D. in mechanics to come here and teach you basic mechanics?

You're kidding me!

You'll be able to calculate the degree of freedom and then teach me okay!

I almost ran away, if I hadn't seen the whip.

Joan of Arc turned the first page and said with a smile: "Let's learn basic mechanics first, come, this is the first chapter, first remember a concept, that is, what is machinery." ”

I meow......

Well, I'd better sleep.

After years of hard study, I had already practiced the magical skill of standing and sleeping on the bus to school, I found a fulcrum and leaned on, and then closed my eyes to sleep.

I have to admit that having the teacher's words in my ears is too much to help sleep.

As Teacher Joan of Arc recited the concepts to me in a "simple way", I fell asleep within 30 seconds!

I don't know how long I slept, but I knew I was woken up.

Teacher Joan of Arc held a whip in front of me and said angrily, "Oh, can you not sleep in class!

Ah!

Teacher, don't you think your mantra is too ......

I said helplessly: "Teacher, it's so boring, either let me make something, or let's do something else, can you stop lecturing!"

Please, I'm a scumbag now!

How can a scumbag like to go to class!

However, a certain teacher seemed to have misunderstood what I meant, and said to me angrily: "Do you know you? Come, tell me about the concept of machinery!"

This teacher is not bad, although the lecture can make me forget when I fall asleep, but when I ask a question, I still know how to mention the first concept of my own speech.

I guess she asked because she thought I could remember.

Although I think another reason is because she didn't memorize what she said later.

The teacher asked a question, so I simply answered.

I just said lightly: "Machinery, the English name (machinery), refers to the general term of machines and mechanisms. In general, machines were invented to help humans reduce the stress of their work. Teacher, am I right?"

Joan of Arc looked at me in surprise.

Truth be told, I've been asleep for quite a long time, at least half an hour.

With Joan of Arc's ability, she also knew that I slept for a while, and she didn't talk about it after I fell asleep.

Of course, I only found out about this later.

Now I can only see my teacher Joan of Arc looking at me in surprise.

Of course, I guess it's because she doesn't know what English is.

But there are many races on this continent, and they have everything to say, so she doesn't care much.

After a good night's sleep, I was refreshed, and I was in a better mood, so I said boredly: "Teacher, just tell me what the spiritual science department is for, and don't worry about anything else." ”

I don't know why, but my arrogant words didn't arouse the anger of Joan of Arc, but she explained to me, "The original meaning of the creation of the spiritual science department was to allow ordinary humans to have the same fighting ability as cultivators. What we have to do is to design and build a machine that is powered by spiritual power. This is the original intention of the establishment of the Department of Spiritual Science. It's just that this idea has been shelved for many years because it has not been taken seriously. ”

I laughed when I heard it.

What's so hard about that?

Whether it is kinetic energy, hydro energy, nuclear energy, as long as it is energy, then it must be used.

Spiritual power is naturally also a type of energy.

Replace humans with energy to drive machinery, how difficult is this, tell me?

I invented the flushing toilet at home!

I nodded, indicating that I knew, and then said, "Okay, I see, thank you, teacher." ”

After that, I found a clean place and wanted to go and get some sleep.

But Joan of Arc didn't seem to want to let me go, she grabbed me and said to me eagerly, "Then can you make this device move?" As if afraid that I would play with it, she said, "No human power is allowed." ”

What's so difficult about that!

I looked around and basically found all the materials I was looking for.

I have to say, it's pretty good to clean up all the dust here, and then the dust on the metal that I don't know how long it has been stored has also been cleaned up by my Joan of Arc. This rose house is also much cleaner and richer than it looked before.

At least I've seen several rare minerals, and most of the materials I need can be found here.

However, there is one key thing that I am missing.

That is, how do I do it?
