I started translating grimoires with Arisa.

How do I translate this word?"

It's 'absorb' because it hangs on the heat of the subject."

　Alisa nodded in agreement. The time spent working alone with Alisa was somewhat enjoyable. However, we were not alone in the room. Tamegoro was lying down beside me, and Taabo and Hakuro were wrestling on his back.

Where are Chika and her friends now?

I think it's about four layers. I think they're flying over the desert. I don't think they have anything to worry about."

Yes."

　The door to the workroom opened and Toshizo brought coffee.

Why don't you take a break?"

　Toshizo's speech and gestures seem to be starting to resemble Kongoji, the butler. Arisa noticed that Toshizo was wearing makeup.

Does Toshizo wear makeup?"

'I'm working with Elmore on makeup that won't look unnatural when I go out.

How about asking a professional makeup artist to teach you?"

'Well, there's a profession for that. I'll think about it."

'By the way, have you tried giving and to the metal?'

Well," he said, "I'm not sure. ＜We are experimenting by making a plate out of silver that has been given only repulsion (earth). I have confirmed that the buoyancy changes depending on the amount of magical power that is poured into the silver plate with this property.

Can I see that Soginban?"

　I take it out of the storage armlet and hand it to Alisa. It is an oval-shaped metal plate about 70 centimeters long. A conductor is connected to the tip of the silver plate, and when Alisa grips the conductor and pours magic power into it, the plate comes to life.

Be careful if you try it, if you lose your balance you will fall."

　Alisa carefully placed one foot on it and put her weight on it. The weight made the Soginban sink a little, but it returned to its original height when the amount of magical power to be poured into it was increased.

The buoyancy is much stronger than I thought it would be."

Yes," he said, "but it is difficult to rapidly increase buoyancy above an altitude of four meters. But once the altitude exceeds four meters, it becomes difficult to rapidly increase buoyancy."

　Arisa seemed satisfied to confirm the power of .

If you stumble upon this tale on Amazon, it's taken without the author's consent. Report it.

　After that, we continued translating grimoires and finished the day. By continuing this work together, Alisa and I began to feel closer to each other.

　The translation process revealed that one of the unregistered granted magic could be used for hover vehicles. It is a magic called "Forced Braking". This is a magic that forcibly slows down the speed of the target object.

　There is also a magical element present in this magic, and it would be a great brake if the engraved magical element were incorporated into a hover vehicle.

　The next day we went out to buy some equipment and magic boards that Amane said we needed. Before shopping, we stopped by the Adventurer's Guild.

　Someone at the reception desk informed the branch manager that I had arrived and asked me to go to the branch manager's office. Alisa and I went to the branch manager's office, where Branch Manager Kondo was waiting for us.

Would you mind if I join Alisa?"

Of course, that's fine. The coiled peach was sold at auction, and I thought I'd let you know the result."

　One coiled peach alone was sold for over 100 million yen. Since I had 11 coiled peaches on display, even after deducting the handling fee, about 1.1 billion yen would be deposited into my account.

　Alisa was surprised to hear that. She had not expected coiled peaches to be so expensive.

When we went to get the coiled peaches, we were all going to eat one."

It's okay," he said. Because the experience of eating coiled peaches will be a valuable one."

But it takes courage to eat something that costs over $100 million.

　Branch Manager Kondo nodded as if he understood the feeling.

By the way, has Mr. Montaner returned?"

　The branch manager nodded.

"Ah, I came back with eight coiled peaches," he said. It seems that they camped for a few days in the coiling peach forest and waited for more ripe coiling peaches to grow.

It's getting fewer and fewer."

I don't think that's an option," he said. Mr. Montaner arrived just after Mr. Grimm collected the coiled peaches.

　Montaner seems to have used a mythical magical weapon, the "flotilla," to freeze the running slugs with a single blow and break through the slug meadow.

　While I developed new magic and finally broke through the slug meadow, Montaner, who is in the top hundred in the ranking, broke through with ease. Considering this, it seems that the ranking reflects the difference in ability.

　He then went shopping at a store used by magic artisans before returning to the mansion to continue his translation work for two days.

　When the translation of the grimoire was about half finished, Amane and his team returned. This time, they seemed to have mined about fifty kilograms of white bright steel.

　About 25 kilograms of characteristic-imparted white bright steel would be enough, but Alisa and her team probably intend to make a hover vehicle for their own use as well.

　Alisa explains about the "forst brake" found in the grimoire. Hearing this, Amane's eyes lit up. This is because this magic element has a wide range of applications.

What possible applications?"

　Yukari asked.

Yes," he said. It could be applied to brakes on vehicles, and it could be used in place of parachutes."

　I am impressed by the idea. A magical device that slows down the speed of the fall so that the fall is slower could be in high demand. However, since it would be expensive, it would be purchased by companies rather than individuals and used by their employees.

　The five of us then discussed the structure of the hover vehicle. The basic shape was to be like an airboat used in shallow waters, but instead of propulsion by large propellers, compressed air propulsion using the magic element of "Air Compression" was to be used.

　Amane and Arisa were in charge of developing the propulsion system and brakes, while Chika, Yukari, and I were in charge of designing the airframe. When most of the design was completed, we approached an airboat manufacturer to see if they could make one.

　The manufacturer responded that they could make it, so we placed an official order. The frame will be made of aluminum alloy to make it lighter, and on the outside of the frame, a thin sheet of white bright steel with the three characteristics of , , and will be attached to the frame.

　＜Vector control was added because it was predicted that the repulsive force of the "repulsion (water)" would react to the water in the human body. The repulsive force was controlled to work only downward using .

　A prototype of the propulsion system has been completed. It resembles a jet engine on the outside, but inside is a scupper. Inside, there are only a few magic circuit boards that incorporate the magic elements of the "Air Compression" system. All that remains is a magic battery and a device that controls the flow of magic power.

　When we tried it out in the underground practice field, we heard a low "go" sound, and a jet of air was released from the propulsion system's jets at a great speed. The propulsive force was strong enough to accelerate the hover vehicle to a speed of about 50 kilometers per hour.
