Since there seemed to be nothing more that could be done that day, Jin and Reiko landed and returned to the laboratory.

Jin, with the help of Reiko, creates the basic data for 3D maneuvers.

This data will be used for other golems and aircrafts without having to start all over again.

The work is completed by storing the data in the old man's memory bank.

Jin then modifies Reiko.

"Well, the current method would probably work if it were not for Reiko. ......"

Sudden acceleration, sudden braking, sharp turns. All of them must generate tremendous acceleration.

"Not tens of Gs, but hundreds ...... of Gs.　Acceleration?"

Jin suddenly thought back to the operation method of the force field generator.

"Force, after all, is equal to the acceleration exerted on a mass. In other words, ......"

If used properly, there is a possibility that the acceleration pressure called "G" will not be generated.

"<> is the case ...... because the force is exerted only on the necessary objects. ......"

The current force field generator "Force Generator" is exerting force on a point. Jin's idea was to ask if it is possible to exert this force on the entire object.

"Of course we can!"

Based on this idea, he improved the force field generator "Force Generator.

"With this method, we should be able to freely rotate and move in a straight line.

The force generator has been improved so that it can determine the called Reiko and exert its effect on it. This includes objects that Reiko holds in her hand (limited to a certain size) or wears.

This has the advantage of eliminating the effect of inertia, since the same force is applied to each atom of the material that makes up Reiko.

Reiko's 3D maneuvering until now was possible because of her strong body. If a living creature could do the same, it would be flattened by inertia.

It took about an hour to complete the modification.

A special Magni Reactor was also added.

Having such an independent energy source improves the reliability of the system.

In addition, the usual overall review, maintenance, and adjustment are also performed. Jin, who is even more concerned about the weight, succeeded in getting Reiko's weight back to the original 30 kg, while increasing the strength by 5 percent by changing the materials.

"Okay, Reiko, <>."

"Yes, father."

Reiko got up and told him that her condition had not only not changed, but had even improved.

"Please test the operation."

"Yes, sir. I'll be right there!

Reiko slowly rose out of the institute and flew freely in the dusk sky.

"Father, it's amazing. Your body is as light as a feather. And yet you are full of power!

"Well, it's a great success!"

Reiko says a little excitedly as she lands on the ground. It must have been the first time for her too.

"With this, I'm sure I won't lose my weight when I push heavy things, for example.

"Oh, yes, that's right."

For Reiko, who weighs only 30 kg, it was mechanically impossible to push a 300 kg object unless her feet were firmly on the ground.

From now on, however, the force field generator "Force Generator" supports her.

Reiko is now even more powerful.

"Okay, that's it for today. Let's have dinner.

Under the sky where the early stars were twinkling, Jin and Reiko went to the house guarded by Soleil and Luna.

Soleil made dinner of white rice, miso soup with wakame seaweed, meat topopo, fried eggs, hijiki and deep-fried tofu, and pickled Chinese cabbage.

Jin ate as much as he could because of all his favorite foods.

Today, unusually, Jin is the only one at home. Hannah and Elsa are also absent. Reiko, Soleil, Luna and the others are basically silent unless Jin speaks, so the house is quiet.

All he hears is the sound of insects, and Jin feels a little lonely.

"...... I'm going to take a bath."

It is already dark outside, and the moon is rising. Jin headed for the open-air bath.

"Ah, it's so relaxing.

Jin stretches out his arms and legs and relaxes in the hot spring. Reiko is with him.

"Your father has been very busy these days."

Reiko seems to be in a good mood, alone with Jin.

(I remember the old days. ......)

When Jin was still visiting Blueland and Potrock, it was Reiko who supported him.

Even now, Jin's trust in her has not changed. Reiko is the automaton that Jin trusts the most.

"Tomorrow, I want to apply the force field generator to engines.

If it is applied to aircraft, it will be able to fly in a vacuum. Jin soaked himself in the hot water with various fantasies.

"But, ...... air resistance would be a problem.

Jin is thinking about it. He moves his hands in the hot water, feels the resistance with his palms, and tries various things.

Eventually he got tired of this and dipped the hand towel on his head into the hot water. No one said it was bad manners. The hot water here comes from the bottom and is constantly being renewed, so there is no accumulation of dirt.

Jin played a game called < with a hand towel. It had been more than a decade since he had played this game as a child.

As Jin was watching the air wrapped in the hand towel forming bubbles and making a sound like "ssshhhh", the bubbles popped and disappeared, he suddenly felt a flash of inspiration.

"...... hmm?　Wait a minute."

I remember reading in a comic book about a future technology called <>.

It is only a hazy knowledge that torpedoes and submarines are wrapped with air bubbles to reduce water resistance and reach several hundred kilometers per hour underwater ......, but it was still a revelation to the present Jin.

"If it's propelled by a force field generator, it's irrelevant!"

"Father?"

Reiko looked at Jin who unintentionally shouted out loud with a doubtful look on her face.

"Nn, ah, ah... No, I've got an idea to eliminate the resistance of air and water.

"That's my father!　What kind of method?

"Yes, I knew we could reduce air resistance by using wind shields. But that was not possible because the magical jet propulsion engine (magijet engine) sucks in air and sprays it. But ......"

"So, if it's propelled by a force field generator, it doesn't matter!　That's what I thought. Then you can also say that for the Magi Water Jet, right?

"That's right. The mermaids, for example.

Their underwater mobility will be two or three orders of magnitude different.

I'm looking forward to tomorrow.

Reiko smiled happily at Jin's happy muttering profile.

* * * * * * * * * * * *

The next day, on the 21st, Jin immediately decided to install the force field generator "Force Generator" in Pegasus 1.

Since aerodynamic steering is naturally impossible with the wind-shielding wards in place, the "force generator" is also used to change direction.

The adjustment was rather time-consuming, and unusually for Jin, it took the entire morning to complete. Of course, a new type of wind shielding was also installed.

"Okay. Let's do a test run before lunch.

"Father, it's dangerous, let me take care of this."

As Jin was about to get in, Reiko interrupted him.

"Well, I guess I don't have a choice."

Jin accepted Reiko's offer. He thinks it will be all right, and he will be able to get on the train sooner in the end.

"Well then, I'm off."

Reiko boards Pegasus 1 and takes off first with the normal magical jet propulsion engine (magijet engine).

Jin rushed to the mana telecam at the laboratory and connected it to Reiko.

"Reiko, how are you doing?

<

And Reiko turned on the switch.

Reiko's appearance on the mana telecam does not change.

<

And Reiko turns on another switch.

The mana-telecom still can't tell what's going on. But the old man reported back.

He easily broke the supersonic speed barrier. And that's without sonic booms.

Reiko, is there anything wrong with her maneuverability?

<

Reiko then reported again that she could see Reiko operating the controls for a while, although the mana-telecam could not tell as usual.

<

"Okay, thanks for your hard work. Come back soon."

Jin, wanting to get on board as soon as possible, breathlessly orders Reiko to return to the ship.
