After following Helena for about ten minutes, we finally reached our destination.

If I hadn't followed her to this place today, I wouldn't have known that there is a humanoid store outside the academy.

The location of the store is opposite to the direction of the shopping street, and people usually don't come to this side.

But the store covers a large area and has eight floors.

The whole building is made of metal, and although its exterior walls are painted with coating for preventing sunlight reflection, but the welding marks are still visible where walls are put together.

Moreover, from the markings above the entrance, you can see that different floors correspond to different goods, from ordinary ornamental humanoids to magic puppets and even fully automated humanoids are available.

It feels like in a way this world has surpassed my original world, isn't this automated humanoid actually an AI robot?

"Please come in."

The door of the store opened automatically, and Yuyi pushed Helena inside.

Sighing at the unscientific automatic door, I also followed them into the store.

The store still looks relatively deserted, the first floor is large, but there is only one maid watching the first floor.

Seeing us enter, she hurriedly saluted and said.

"Miss, and young master, welcome back, the master is already waiting upstairs."

"Hmm."

With nodding, we walked towards the metal door next to us.

I have a creepy feeling now, did they even have an elevator? But I could answer that one myself. What other door besides an elevator has with a row of buttons with numbers on the wall next to it?

A microwave oven?

Sure enough, after Yuyi pressed it, the door automatically opened. I have never imagined that I can still see an elevator in this kind of place, my mood is really complicated now.

"...... you don't seem to be surprised at all?"

Finally, when the elevator door closed, Helena turned her head to me and asked.

"I'd be a little surprised if you didn't ask that question, but, I don't need to be surprised at a device that could carry objects up and down, right?"

"Oh, have you ever seen one before?"

"An elevator."

I said.

"I once had read about it from a book."

"From a book ...... it shouldn't be, I'm sure that this is the first place that have such a device installed on the Western Continent."

Although she said that she did not believe, but she has turned aroud to look at me.

"Do you need me to draw out how this thing works for you to believe it?"

"You can draw the structural drawing of this thing?"

"I can also tell you how that automatic door works and even more things you don't have."

"How do you know ......! This kind of stuff would be in a book?"

"I'm not really sure, I just remember I read about it in a book a long time ago."

"A long time ago ...... are you telling me that book isn't here?"

"Of course, but I can tell you the name of that book, it's called 'Physics'"

O my physics teacher who doesn't know if he's still alive, do you know that we have carried your knowledge forward in the other world?

Even in the world of magic?

"'Physics' ...... Is that so? It's the same as what that guy said, this book is really something."

"Eh?"

Now I am the one who surprised.

"That guy ...... you mean there is other people who has also told you that he has read this book?"

"Well, about half a month ago, when a person called Lester was trading some material from us, he traded us with 'Outogate' and 'Alevator' which are the design sketch of what you call the elevator, like he said, he also saw these from the physics book mentioned above. But after we confirmed the feasibility of the sketches, the man disappeared. So, we made the two things."

I can't believe it was that guy Lester ......

"Lester, I do know him, but did he come to our academy too?"

"No, it's in Mai City, the border city of the Eli Empire, where we have a branch store."

Did that guy actually run away to the Eli Empire? He ran really fast, but I wonder if he found what he wanted from the underground labyrinth.

"In that case, if you can meet him next time, tell him that, 'Fir is angry and the consequences are serious'."

"Hahahaha ......"

Helena puffed out a laugh.

"So you and he are really similar in some way, that guy makes people feel that he always has strange thoughts like you. But since you also know a little about that book called 'physics', I'll have to ask you later."

"...... only if you can give me some books about high-rank thunder magic and how to make a humanoid."

She froze when she heard that.

"What's wrong? No?"

"No, no, no, how could I say no, of course I can!"

By the tone of their voice, they are still happy?

Why do I feel like I'm at a disadvantage?

"We have a lot of books of thunder magic in our house, but about making humanoid ...... although we can teach you, it's not a simple thing to learn."

"No problem, you can also give me some related books. It might be more convenient for me to read them myself."

After all, with the assistance of the system, reading books is certainly fast.

Although I can learn by teaching me in person, but, I have never really tried making items.

Is it simple like just pressing the make button?

That would definitely scare people to death. I don't know how I succeeded when I taught Yaling magic before, but there was always something inexplicably weird about it.

"We definitely have the books you want, but we're more interested in knowing what the book called 'Physics' has in it."

"Depends on what kind of information you guys want."

"Is that so ......"

The elevator soon reached the top floor, and with a ding, the door slowly opened.

It seems that doing business in this world is also quite profitable, these exaggerated decorations can really be comparable to that villa Fran bought at a heavy price.

"Oh, today we actually have a guest ...... If I remember correctly, you should be Fir who had a match with my little girl this morning."

In the middle of the room stands a middle-aged man wearing a dress, other than that, the most profound impression he gives me at the first glance is his face with a scar.

"Nice to meet you, Mr. Simu."

I responded with a smile.
