"Hey, girls, have you had lunch?"

"Oh, we're fine, we've already eaten."

　Hannah is convinced by Jin's answer.

"There's the time difference, isn't there?"

　Hannah and Martha have lunch.

　Jin, Elsa, and Reiko are waiting in the workshop.

"Hey, honey, thanks for waiting..."

　Hanna comes out of the house after lunch.

　And then Hannah said..,

"I know I said I was going to experiment, but first I wanted to show you something.

　She said, and started walking toward Nido Castle.

"Something you wanted to show me?　I wonder what it is.

　Jin, Elsa, and Reiko followed.

　Less than 10 minutes later, they arrived at Nido Castle.

"Well, you know, it's in the lounge on the second floor.

　There is a lounge by the window on the second floor, where people can chat, have a snack, or read a book.

　Few people use it, though.

　And what did Jin see there?

"Drawings?"

"Yes, it's the first drawing of the Free Aether Transfer Device!"

　Hannah said something shocking.

"What?

"Did you draw this, Hannah?"

　Jin, Elsa, and Reiko were surprised.

　Hanna had created the Magi machine, which Jin had worked so hard to realize, but had been unable to do so in a satisfactory form.

　The mobile base and the that had been confiscated had been destroyed and could not be analyzed.

　Jin felt that it was too late, and that was all.

　However, if Hanna had reproduced it, it would have been a different story.

"Oh, this is just a drawing, and there is a possibility that it would not work if you actually made it, right?

"That's true, but ......."

　Jin stared at the drawing, still half-amused.

"Let's see... ......"

　Hannah explained.

"I've been thinking about it a lot too. First of all, I asked the old man how the warp gate works.

"That's great, Hannah."

"So, I thought that the warp gate is a subspace tunnel connecting two locations. And the tunnel has a spatial gradient and is normally set to one-way traffic."

"Yeah."

　This is the same as what Jin also guessed. Hannah is thinking independently, and it can be seen that her ideas are extraordinary.

"So, when an object enters the starting point of this , it is forced to move through the , but I think it pulls the of the object to be transferred, and the object following it is transferred, didn't I tell you before?"

"Yes, I heard that."

　If the object is wet, the water on the surface will be transferred along with it. Also, if it is fur or feathers, the air between them will be transferred together.

"Based on this, I thought about how to send free magic element (ether).

"Mm-hmm."

　Jin was drawn into Hannah's explanation.

Read at https://w w w . m t l r e a d e r.com

"First of all, we have to increase the concentration of free magical element (ether).

"I understand that."

　By increasing the concentration of free magic element (ether) in the sending side, we can create a difference from the receiving side.

Read at https://w w w . m t l r e a d e r.com

　If there is no difference in concentration, there is no meaning in the transfer of free magical elements (ether).

"You can raise the concentration of free magical element (ether), right, Onii-chan?

"Yes, I can."

　Jin has made an ether condenser in the past.

"Using it, we can increase the concentration at the sending side to at least 10 times that of the receiving side."

　In this case, the concentration is the ratio of the space allowance.

　The highest value of 100 percent of the concentration of free magic element (ether) is, of course, the maximum amount of free magic element (ether) that the space can accept.

　According to Jin's assumption, free magic elements (ether) are one of the elements that compose the space, and they are arranged in a cubic grid.

　Then, what happens when the number of free magical elements (ether) increases from a state of 100 percent free magical elements (ether)?

　The answer is <.

　I call it < for the time being, but it is actually not the same thing.

　If there is an object, it enters its interior and creates <>, or creates <> such as <> or <>.

　If there is no object, only free magic element (ether) precipitates and crystallizes. This is the .

"Well, I hadn't thought of that."

"Hannah, that's great!"

　Hannah's explanation was beyond Jin's imagination. Especially the part about the creation of magi crystals.

"I thought that magi crystals were free magical elements (ether) that had entered the in the crystalline structure of pure matter.

　Hannah nodded at Jin's words.

"Yes, I think that's the case with ordinary . What I imagined was a crystal of pure free magical element (ether).

"Is there such a thing?"

"Well, I don't know. It's just my imagination. Maybe someday you will find it somewhere in the universe. ...... But more importantly, let's talk about free etheric transfer!

　Hanna herself says she is not sure how accurate her theory is. Her attitude was already that of a top-notch researcher, Jin thought.

"Let's see, <> and what follows is transferred>>, only one particle of free magical element (ether) is sent in a single transfer."

　Indeed, that would be the case with this theory. It would be the same for air molecules.

"So, we just need to devise a way to put the free magical element (ether) together."

"I'm getting the idea.

"The first thing I can think of is to prepare a container for free magic element (ether), put free magic element (ether) inside ......, and place it in a place with high concentration of free magic element (ether), the concentration inside will naturally become the same as the surrounding area, right?"

"That's right."

　Jin could imagine what Hannah was saying and waited for her next words.

"If we transfer the container and open it at the receiving end, the free magical element (ether) inside will overflow outside, right?　I've never done that before."

Read at https://w w w . m t l r e a d e r.com

"Yes, Hannah is right.

　In fact, it is more of an ether tank than a container, but it does not affect Hanna's theory at all.

"We send that container back through <> warp gate, and send it back when we fill it with free magical element (ether) again."

　Can we call it a piston transport by two warp gates?

　Certainly, the method Hannah describes seems to work with reasonable efficiency.

"......I think anyone can probably come up with that much."

"What?

　To my surprise, there was more to Hannah's story.

"What you really want to do is to transfer free magic element (ether) directly without using a container, right, Onii-chan?

"Yes, well, that's right. ......

"So I was thinking. That's the second one, but this one is still just a theory.

　Jin listened to the explanation, beyond impressed, astonished that Hannah could really think freely.

"Didn't you ever think of using a transporter to send free magic element (ether)?"

"......"

　Jin exclaimed. Elsa was also at a loss for words.

　That was the first thing she had thought of, but Jin recalled that the experiment had been ineffective.

　He had not approached them since then.

"You know, I think we can do something if we change the magic formula of <> and <>. ...... this one is completely in my imagination."

"Kya."

　Jin realized that the method had a good chance of success and picked Hannah up in his arms.

"Let's experiment right away!
