"Fire? Did you know that warding against fire actually protects against cold?
In other words, it blocks heat. To Jin who pointed this out,
"I didn't ...... realize that."
Bina looked at Jin,
"Are you amazing?"
Reiko responded.
"Your father is the best in the world."
"Yes, yes. Yes, of course. Your father is the best in the world. ...... then the problem is the magic that cools him down."
Bina flushes for now. And Reiko frowns. Hitoshi is going at his own pace,
"It's easy just to cool it down, isn't it? There's magic to make ice.
"The easiest way is ice. That's what it is.
Ice is a magic that freezes water and things.
"That's good, isn't it? You make ice in a box, and when the box runs out of ice, you make more ice."
"Oh, I see! That way, it doesn't have to run all the time!
Beena's idea is becoming more and more solid.
"Oh. That's why ......"
When Jin tries to describe the flow of magical control (the Magi sequence), she says, "Wait a minute,
"Wait a minute. Let me tell you. ...... ice creation, ice monitoring, ice creation, repeat. And the ice monitoring is to make ice when there is no more ice.
Thinking for a moment, Jin adds.
"That's right. I think it would be better to do it a little before the ice runs out. I think that's all we need to do.
"Yeah, yeah, I think we can do that.
So we start by making a box. The basic structure is made of wood and reinforced with bronze in key places. The box was made vertically, in the shape of a modern refrigerator, and an ice compartment was built at the top.
"So this is where you make the ice?"
"That's right. Because cold air goes down. Ice is basically at the top.
I envy your knowledge of such things, Jin.
And now for the important cooling part. The work of writing the magi formula on the plate.
"Like this, like this, like this, like this..."
Bina writes little by little while racking her brains. This is of course done by magic.
"I think it would be better to do it this way..."
"Oh, yes, it would be shorter that way.
<. Jin supervised Bina as he built up a decent Magi Formula.
"Okay, that's it. What do you think, Jin?
Jin looked over the Magi Formula,
"Yes, I think it's good. This will give us enough time to make a simple warding inside the box."
"That's right. I've never known the difference in the consumption of magic power depending on how good or bad one is at using the Magi Formula.
Then, the plate is assembled and the magi stone, the source of power, is set, and the machine is complete.
"It's done!"
"Good job! Let's try it now. We can put the Persica inside, right?
Yes, that's right.
So we put the 12 remaining Persicas inside,
"Cooling".
I let it work. After a short wait, I opened the door and found that ice had formed on the top of the inside of the box. This seems to work.
"Well, it will be night soon, so I'm going home.
"Really? Thanks for today, Jin. Will you come back tomorrow?
"Yes. Yeah, I'll see you then.
With these words, Jin and Reiko left Bina's workshop.
