86 - 04-02 Failure is the source of success.





The next day, Jin decides to start with the magic tools for communication.

The method of transmitting information to distant places is known to him through the magic eye and the magic screen.

The free magic element (ether) that fills the space vibrates under certain conditions, and its waves are transmitted to distant places. It is just like the relationship between air and sound.

We have developed a magical device that can communicate voice using this element. We call it the "manacam," or magic element communication device.

By combining this with the magic eye and the magic screen, we have created the mana-telecom.

"Okay, we can communicate with the ground with this on board.

The next device was a protection device.

"We can apply warding to cut off the physical effects on the body.

The idea was to avoid injury from a broken aircraft.

It was relatively easy to create a magical device to generate wards that prevent physical blows. This is placed under the seat.

Then, we think about escape.

The first thing that comes to mind is a parachute. Jin made a parachute from the threads of a ground spider. It is light and strong. And also,

"A small magical jet propulsion engine (magijet engine), which would slow down or change the direction of the fall when parachuting.

Unlike the parachute, it is unknown whether this engine will work or not, so it would be better if it never comes into use.

So, after the safety measures were taken, we started to build the second prototype.

The basics were the same as the first prototype, but the shape was made more sophisticated and the parts that needed strength were reinforced with adamantite.

In addition, it is a double-seater, and a seat is provided for Reiko.

So far, so good.

The problem is how to keep it from absorbing solids.

Jin had been struggling with this problem for a while, but suddenly had an idea.

It is a physical barrier that is also placed under the sheet.

This is a barrier in the modern sense of the word. But those who are inside will not be deprived of oxygen. In other words, air is allowed to pass through.

"Oh, but if the wind speed exceeds a certain level, the air cannot pass through, right?

<<><>> and other magic winds do not pass through.

"Let's see, I see, the Magi Formula (Magi Formula) here is ......, I see, so this is where it is specified."

Jin then investigates the Magi Formula for physical wards.

He showed that he was not a master at evaluating the warding equipment created by Bina in the Blue Land before.

As a result, a repulsive ward was applied to the air intake, which repels substances other than gases, i.e., liquids and solids.

This field is designed to cover the entire airframe, making it a de facto barrier. The only drawback is that it allows wind magic to pass through.

Finally, spare magi crystals, which should be called spare fuel, can be loaded. In case the ether converter fails, we will be able to land safely.

"This concludes the possible security measures."

The control core as a navigational aid system will be recovered from the crashed one and its information will be copied, so that the flight will be stable from the beginning.

"Okay, let's go."

In the early afternoon, Prototype 2 with Jin and Reiko on board soared into the sky of Horai Island.

"Wow, it feels good after all."

Jin was literally in high spirits after flying for the first time. Incidentally, Reiko was mainly in charge of piloting the plane.

"Father, this plane is more stable.

The detailed adjustment of the shape seems to have been effective, even though it was adjusted by intuition.

"Failure is the source of success, as they say. The newer the model, the better it should perform."

Jin then starts practicing to be able to fly the aircraft himself. His instructor is Reiko.

"Get used to it little by little."

Gradually, Reiko took over the controls from Jin, and by the evening of the same day, Jin was able to fly the plane by himself. This was only possible with the help of the navigational aids.

"Ah, that felt good."

Jin is in a good mood after landing safely. Reiko also looks happy.

"I think I'm going to have a good dream today."

Jin walked lightly to his home where Soleil and Luna were waiting for him to prepare dinner.

The next day, Jin finally decides to try building a boat himself.

The shape of the boat was a trimaran. Like a catamaran, a trimaran is suitable for high-speed sailing. In addition, the center of gravity can be lowered because power and accommodation can be placed in the center of the hull.

The hull is made of light silver, which is the most common color for catamarans. And the engines are made of "",

"The engine is ...... this one!"

It is the Magi Water Jet, a magical water propulsion engine developed based on the Magi Jet Engine.

It is simply a replacement of wind magic with water magic, but it is also very efficient. This is not surprising, since the principle itself is different from that of real water jet propulsion.

"It's OK as long as it doesn't suck in dust."

Having learned from the bird strike accident, the team took countermeasures to prevent the jet from sucking in water plants and other debris.

After lunch, Jin and Reiko took the boat to Tatsumi Bay. Soleil and Luna were also to carry the boat.

"All right, let's go on our maiden voyage.

Unlike airplanes, boats are relatively safe. Jin piloted the ship.

Since he does not know the control system of a ship, he uses the same system as that of a car. The gas pedal is used to drive, the brake is pressed to deploy the brake plates in the water, and the lever is used to switch between forward and reverse. The steering wheel is used to turn left and right.

"Oh, this is comfortable.

The prototype boat navigates the calm waters of Tatsumi Bay.

"All right, let's test the maximum speed."

Jin presses down on the accelerator pedal as hard as he can. The trimaran picks up speed, reaching a maximum speed of about 70 kilometers per hour.

"That's good enough. Well, Reiko is faster than me.

Jin mutters to himself as he looks at Reiko in the passenger seat. Reiko smiles happily when she hears this.

After having successfully maneuvered the boat for the first time, Jin returned to the port where Soleil and Luna were waiting for him.

"Okay, let's call this prototype ship <>.

Hydro" means "of water" or "of hydrogen. It might be an unusually good name for Jin.

"Yes, let's name the plane <>.

It was an albatross, but he liked the sound of it, so he named it so.

The next day.

"Well, now that we have the ship and the plane, let's start mass production.

He wanted to use the ship for island defense and the plane for defense, reconnaissance, and of course, understanding of this world.

"Reiko, have Soleil build 30 planes and Luna 30 ships.

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


"Yes, sir."

Since the prototypes were duplicates of those made by Jin, Soleil and Luna could easily make them. Just for the record, no ordinary golem in this world, let alone the best golem in the world, can do such a thing.

Although Jin is unaware of it because he has nothing to compare it to, only the technology possessed by the Magecraft Meister can create such super advanced golems and automata.

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


"So, I'm going to make a golem to put on a ship and a plane. Reiko, help me.

"Yes."

This time, the golem is made of light silver, giving priority to lightness.

Since I have done this many times, I easily completed 40 golems.

As I mentioned before, light silver is an isotope of titanium, so its color can be changed by the oxide film on its surface. Therefore, the golem for the sky is light blue, and the golem for the sea is navy blue.

"Okay, let's put it all together <>level 4....... Okay, I'm getting used to this."

In the beginning, I transcribed some unnecessary knowledge, and Jin's workload was heavy, but I got used to it after doing it many times, and now I can transcribe the necessary knowledge in a short time.

"Naming, Sky 1 to Sky 20, Marine 1 to Marine 20".

But my sense of naming had not changed much.

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


"Sky 1 and Marine 1 as captains, Air Force (Air Force) and Navy (Navy), respectively."

This did not improve Horai Island's defensive capabilities much since it was not equipped with weapons.

"I don't want to make ...... too many weapons, but I guess that's the way it is in this world."

In a world where there are even demons, Jin decided to let go of the need for a force for self-defense.

"That being said, Sky1, you will use your men to scout around this Horai Island and make a map of the surrounding area. I'll give you the gist now."

Using transinfo, we can teach them what they need to know in an instant. This is more efficient than the human counterpart. Trans-info does not work on humans.

Jin was looking forward to the result, as he was sure that he would be able to find out the location of Horai Island in this world, which had been on his mind for a long time.

"Now, let's think about weapons and armor.

Jin's desire to create new weapons and armors was unrelenting.

"First of all, the armor.

Jin went to the warehouse in the basement of the laboratory to look at the materials and think about it.
