The night of May 19.

The next day, the 20th, was the day he was supposed to return to the Shoro Empire as promised by Reinhardt.

Jin was in Horai Island discussing with Laokun, Anne, Reiko, and others.

The contents of the discussion were the plans for the future reinforcement of the Horai Island forces, including the anti-demon forces.

"First, let's take care of the things that can be done immediately.

Jin's words echoed.

"You said your stealth was detected?"

Stealth is a magic that refracts light rays in the visible light range to show what is behind it, making it apparently transparent.

This corresponds to the human visual organ, the eye. Ann advised me that the demons can probably see in the ultraviolet region.

Insects are said to see ultraviolet light, and some reptiles have infrared sensing organs.

It would be better not to think of demons as humans.

Based on the above, the frequency band of stealth influence should be broadened in the direction of infrared and ultraviolet rays.

In order to distinguish this from stealth, Jin calls it .

"Well, it's very effective, but you won't be able to see anything. ......"

Jin, who had generated invisible wards on a trial basis, uttered such a line at the beginning of his speech.

As a result of the refraction of light, there is no light at all that reaches the people inside.

"Did you say something about electromagnetic waves with longer wavelengths, like ...... microwaves?"

I dig up my fuzzy memory. Shorter wavelengths are more dangerous because they become X-rays or gamma rays.

I think microwaves are used in radar," Jin recalled, and after consulting with the old man, he made up a plan to strengthen the vision of Reiko and the other Horai-jima islanders.

Jin himself improved Reiko, and left the rest of the golems to Lao-kun since there was not enough time.

Needless to say, the information gathering ability of the Horai Islanders has been improved by these measures, although they are not so impressive.

This is what the old man proposed to Jin.

Regulus, Deneb, Capella, Spica, Mira. I will increase the number of each of them by ten, and dispatch them to the Shoro Kingdom and the Leonard Kingdom.

At the same time, I explain to them that we are planning to increase their power in anticipation of contact with the demon tribe.

The current Reiko's power output of about 15% will be increased to 30%. Also, since she will be heavier than a human, she will be equipped with additional armaments that she did not have before.

The increase in weight will be reduced by cutting out the skeleton, but the strength will be reduced by changing the material from ordinary light silver to 64 light silver.

Since aluminum and vanadium were only added to ordinary light silver, it was a great advantage that engineering magic could be used without having to rebuild the body.

The armament would be < and , and a barrier would be deployable.

"Yes, I think that's a good idea. Let's go along that line."

Jin agreed.

The rest is up to you.

"And then, let's see... ......"

Jin started to summarize the items that could not be done right now, but he wanted to enhance them gradually.

First, the defense of Horai Island.

"What if the demon tribe thought of crossing the sea?

The possibility is not zero. If we can reduce their weight by gravity magic, they might be able to run on the sea.

"Yes. Even demons are living creatures. It will be difficult to deal with an attack from underwater."

Jin was thinking of building a submarine force.

With a crew of golems, food, water, and oxygen would not be a concern, and the structure could be simplified.

Let's say 10 to 20 meters in length."

.

According to the basic specifications that Mr. Jin has envisioned, the old man has decided to proceed with the construction plan of the .

Of course, it would be better to increase the sea power as well.

"I would like to have a cruiser-like ship that can turn in a small radius.

A high speed boat of about 40 meters in length was also included in the plan.

In response to these plans, it was decided to reinforce the Golem force on land, sea, and in the air.

The number of Sky, Land, Marine, and Mermaid golems will be increased from the current 100 to 200.

This can be done basically by the old man alone (of course, the actual work can be done by a craftsman (Smith)).

And, as a decisive factor, the development of a free magic element (ether) absorption ward.

It literally eliminates the free magic element (ether) in the warding. This would be fatal to the demon tribe.

The above can be called a defense plan.

Then, Jin, the old man, Reiko, and Anne plan the next reinforcement plan.

"First, Reiko.

Jin lists up what Reiko lacks now, what functions she wants, and so on. He wanted to make those things possible in the future, even if they could not be done right now.

Jin hoped that he could learn something from the alchemists in the Shoro Empire.

1. self-healing function.

2. improvement of combat skills. 3. improvement of knowledge and intelligence.

3. knowledge/intelligence improvement

4. power-up.

The self-repairing function of 1.

The self-repair function (1) could be performed immediately, rather than through a long-term plan.

It is difficult to completely repair a missing body part, but it is easy to repair a wound in the magical skin or muscle, or a bent skeleton, for example, in an instant.

The method is to embed Magi Crystals (Magi Crystals) with <>, <>, <>, etc., in each part of Reiko's interior.

Then, when Reiko gives the command <, engineering magic with a certain effect will be activated to repair the damage to her body.

While at rest, she may be able to repair herself by applying engineering magic, but doing so in the midst of battle is sometimes fatal, so a repair function that can be activated by a simple command would be very useful.

It is difficult to improve the combat skills of 2.

Jin had always wondered why Reiko used a lot of physical combat. After discussing with Reiko and with the help of Anne, he found a big problem.

That is Reiko's <.

Even Reiko's own <, made of Magi adamantite, weighs about 1.5 kilograms. A longsword made of steel weighs nearly 2 kilograms, and one made of adamantite weighs about 5 kilograms.

When Reiko, who weighs 30 kilograms, wields it, the recoil is tremendous. Since the law of action-reaction is still valid in this world, light weight is not suitable for precise swordsmanship.

Furthermore, <>. This is paradoxical, but Reiko's power is too great.

The difference between 1 and 1.1 against 10,000,000 is nothing. The difference between 1 and 1.1 for 1000000 is equal to nothing. But even the difference of 0.1 makes a big difference against humans.

Reiko is holding back with her amazing reaction speed and control technique, but on the other hand, it could be said that she is using her brain's processing power in a very wasteful way.

"Well, this is my problem.

He was not likely to come up with a countermeasure right away.

"If we can get a better understanding of gravity magic, we might be able to use it..."

It is still fresh in our minds that Lardus had changed the weight of his sword to increase its speed and impact.

Gravity magic was going to be a key technology in the future.

3) Improvement of knowledge and intelligence.

Knowledge was indispensable for Jin to make Reiko a lady second to none, and not only for Reiko.

He will assign the 5th column (Quinta) to collect knowledge and information on this subject.

Specifically, the etiquette of each country, songs and dances that are popular among the people, etc.

Power-up of 4.

In terms of Reiko's body size, it is safe to say that she has been powered up to the limit in terms of physical strength.

In order to increase her power further, she would need more advanced materials.

This was also Jin's challenge.

In terms of magical power, the use of eladolite can easily increase the current power tenfold. This modification could be completed quickly.

"Now, let's see what the old man can do next.

Since Jin had made the "Mere Old Man", no major modification had been made to the "Mere Old Man".

On the other hand, his workload is increasing.

At this rate, it will overflow in the near future.

"Well, there are two ways to increase processing power. ......"

In the case of a personal computer, it is to increase the clock frequency of the CPU (central processing unit). This can be further broken down into raising the number of brain revolutions.

Another is to increase the number of CPUs. This can be likened to increasing the number of people.

Your brain is the Magi Device, which is composed of 8 Magi Crystals of each attribute: earth, water, fire, wind, lightning, light, darkness, and all the attributes.

The processing power will be increased by making many of the same devices and processing them in parallel.

So, Jin made three more magi-devices and arranged four magi-devices at the four vertices of a triangular pyramid (tetrahedron).

The original magical device controls the three added ones.

What do you think, Mr. Newborn?

<

"That's good. ...... and then I'd like to do frequency up ......."

Jin was not fully satisfied, and he let out a soliloquy that could neither be described as a complaint nor a gripe. The reason is that this technology can also be used to increase Reiko's power.

It seems that magic power is an exchange. Since it is an alternating current, it has a frequency. And that frequency is inevitably the same as Jin's unique magic power pattern.

As a Magecraft Meister, Jin's frequency is ten times higher than that of an ordinary mage. That is how high his level is.

But if he could raise it even higher.

This was also Jin's goal for the future.

After finishing the above, Jin gave the necessary instructions to the old man and returned to the Shoro kingdom.

"And then there is a medical golem and ......."

With these words.

* * * *

In Horai Island, the old man was working according to Jin's instructions.

First of all, the fifth column (quinta) was rearranged.

The number of quintas increased from 100 to 150, and they are sent to their new locations again.

They will infiltrate the Shoro Kingdom, the former Leonard Kingdom, and some of them will infiltrate the territories of the demon tribe.

The first thing the Fifth Column (Quinta) does after being dispatched to the Shoro Kingdom is to search for the ingredients that Jin wants.

It soon bore fruit.

Spica 11 and Mira 11, who were sent to the south, reported that they had found three kinds of rice near Lake Wass.

Capella11 obtained a genuine tea tree near Aube.

Now that rice and tea seedlings and processed products had been obtained, it was decided to start growing them on Penglai Island.

On the other hand, the fifth column (Quinta), who were sent to the former Leonard's Kingdom, could not find any demon spoor, but they did find some small settlements inhabited by humans.

<

The old man instructs.

How did the Kingdom of Leonard, one of the small group of countries, fall into ruin, and who set up the illusionary wards throughout the country, and for what purpose?

There were many mysteries to be investigated.

The activities of the fifth column (Quinta) will continue in the future.
