Start with Island Lord

Underground laboratory.

"The power is too poor, it can't fly fast, and once it is discovered, it will be easily intercepted."

"That's right, there is no perfect stealth in the world. Relying on stealth to defeat the enemy is a bit of a gamble."

"The anti-magic and magic-breaking performances are insufficient. If you encounter a super-large-scale barrier supported by a large conversion array, such as a lightning barrier, it may fail directly."

"Although the 30-kilometer range is quite far, it would be better if it could be farther."

"The observation effect of the light and shadow array is very good, but it will be very tricky to encounter invisible targets. In addition, wind, sand, and water mist can easily cause blindness."

"."

In a bunch of hindsight-like analyses, the mages came to a unified view.

The reason why this small flying magic weapon can achieve such an amazing record is not because it has perfect performance.

But because of appropriate tactics and unexpected design ideas.

Once it is used more times and the opponent understands its performance, there will be a lot of defensive means.

Rosen fully recognizes these shortcomings, which is why he called everyone to discuss.

He clapped his hands and made a summary.

"No matter what, the design of this weapon is groundbreaking, its combat effectiveness is amazing, and it can also avoid casualties of soldiers to the greatest extent."

"At the same time, we must also admit that there has never been a perfect weapon in the world, only relatively better weapons."

"My request is to gather everyone's wisdom and polish this new weapon as sharp as possible to help Weilan cope with the next wave of challenges!"

"Of course, I will not stay out of it. In future research, I will always participate in it and contribute my wisdom to protect Weilan."

The Duke's wisdom is not ordinary wisdom, it is wisdom that can reverse the fate of the country.

This is not flattery, but a fact that has been verified many times.

So, many wind mages who knew nothing about making aircraft and were insecure in their hearts all had a backbone.

Everyone began to applaud.

When the crowd was a little quiet, Rosen pointed out several young mages in the crowd.

Five people came out.

Three of them were previously in the aircraft research base on the white sturgeon island.

There are two new wizards, Weilan, who graduated from the Silver Moon High School of Magic in Kao.

Four are senior wizards, and one is a master of magic, the oldest one, but only 33 years old.

At the same time, they are all civilians.

"You guys come with me, let's talk alone."

These five are the most capable engineering research wizards, and have been appointed as the general managers of various branches of the institute.

The five wizards immediately followed.

Rosen took the five people and talked to them about his ideas about the new unmanned aircraft while patrolling the research base.

"What you discussed just now is very valuable, and it is indeed the fatal flaw of this new unmanned aircraft."

"But I believe you can all see that it is extremely difficult to improve the performance of such a complex magic weapon, even just a little bit, right?"

The five wizards nodded.

They were given important tasks, but their abilities were not up to standard, so they studied very hard.

At this time, they also clearly understood the basic principles of unmanned magic weapons.

But the more they understood, the more difficult it was to improve.

When talking about it, everyone is very relaxed. With a touch of the upper and lower lips, everyone can talk about a lot of truths.

But when it comes to doing it, there are unattainable thresholds everywhere, which makes people feel desperate and have no way out.

There is an insurmountable gap between "pointing at the world" and "changing the world".

Most people can only stand by the ditch and watch the excitement, while those who can really cross it are the protagonists on the world stage.

The only magic master among the five is Belladlin. He graduated from the Kao Silver Moon High Magic Academy and has been teaching at the academy for nearly ten years. He has even been promoted to a magic professor.

The decent position and decent income allow him to have a decent life in Kao Silver Moon City.

The reason why he left everything and returned to Weilan was because he admired the Duke's magic achievements.

And he was indeed valued by the Duke.

He sighed: "My Lord Duke, I used to think that my research on wind magic was quite in-depth, but compared with you, it feels like a beginner meeting a master. I didn't know that high-speed airflow has so many special properties."

Rosen knew that he was referring to the gap between aerodynamics and the basic properties of gases.

He smiled and said, "Mr.'s research on gas temperature and pressure performance is also extremely valuable. They are two sides of the same coin of airflow properties, and there is no difference in superiority or inferiority."

After a pause, he said, "You said before that you wanted to increase power. It seems that you have a new idea?"

Beladrien immediately said, "My idea is the same as that of large manned aircraft, using ultra-high-speed airflow reverse thrust to obtain power. But the implementation method is different."

After a pause, he said, "Because unmanned aircraft are not sensitive to endurance, 50 kilometers is very good, so I thought, should I compress the airflow violently and then store it in a can, and when using it, spray it directly from the mouth."

Rosen smiled and said, "It's a very good idea, but it is very difficult to compress the airflow, and the final jet speed is not fast."

"Indeed, but my idea is that when necessary, use the fire rune to heat the gas tank, give power to the airflow, make it more violent, etc. ~"

As he was talking, he seemed to have thought of something and suddenly paused.

Rosen was not in a hurry, and raised his hand to tell others to stop talking and let them think quietly.

About a few minutes later, Belladrin suddenly said: "Duke, I suddenly thought that maybe we can use dephlogisticated water and phlogisticated water for mixed combustion instead of gas tanks, and then directly spray out the high-temperature steam after combustion, which will definitely get a very huge power."

Dephlogisticated water is hydrogen. Phlogisticated is oxygen.

So Belladrin's inspiration is actually to create an alien version of the hydrogen-oxygen rocket engine.

This is awesome stuff.

Rosen nodded repeatedly: "What a wonderful idea!"

"If it really works, the drone can not only solve the power problem, but also the endurance problem."

"I think so too!"

"Then you can follow this path, and I will allocate resources to you."

"Yes, Duke."

Belladrin was excited, because this wonderful new idea opened his mind, and a lot of new ideas suddenly emerged in his mind.

Rosen saw it and said, "Go back to your laboratory and do experiments, mage."

Beladrien ran away.

Rosen continued, "Mage Humer, the gyro balance rune is a very subtle and powerful knowledge. It all depends on you to improve it."

Mage Humer came from an island and was a taciturn but very reliable mage.

Nodded, "Leave it to me, lord."

After that, there were three more mages, who were responsible for the explosion unit, the stealth unit, and the flight control unit respectively.

Rosen also encouraged them one by one and pointed out several possible useful directions.

Obviously, his guidance was very useful, allowing the three mages to find a clear direction to move forward, which greatly dispelled the confusion of the three.

At the end, Rosen encouraged: "In the foreseeable future, this kind of unmanned explosive aircraft will be the core weapon for protecting the island."

"Its performance can directly determine the outcome of a war."

"The safety of Weilan and the fate of Weilan's 30 million citizens are on your shoulders."

The four mages are all civilians, and the good core positions have always been monopolized by the nobles.

They never thought that they would be able to shoulder such a huge responsibility one day.

For a moment, I felt heavy in my heart, and I felt an incomparable sense of honor and mission.

Unconsciously, I clenched my fists and pursed my lips, as if I wanted to snatch the treasure from the hands of the Creator.

This is the spirit Rosen needs.

He raised his hand and gently patted the shoulders of the mages: "Go forward, young people~"

Even though he is only twenty years old, he makes people feel that he is an elder who has experienced countless times.

The four mages were obviously much older than him, but they all felt like fresh-headed young men who had just graduated from the academy. They immediately felt a sense of being trusted and valued, and their blood boiled unconsciously.

They were like ponies encouraged by their elders, and they threw themselves into work with full enthusiasm.

Rosen looked at their receding backs and thought to himself: "The civilians who just stood up from the mud are simple and honest. After a few generations, there will be more naughty ones."

This first generation of citizens has not seen the world yet, and naturally has a spiritual foundation of Puritans and ascetics.

They are the most down-to-earth and hardworking. As long as they are used well, Weilan's national strength will rush forward like a train.

I also believe that in the near future, the second and third generation of unmanned blasting aircraft will be produced.

I thought of Danger on the other side of the sea again, and sighed in my heart.

"This guy is strong, but he slaughtered all the nobles in the country at once, leaving the common people and the king without a buffer. I'm afraid he may not be able to handle such a complicated relationship."

He can handle it.

Because he is not only a duke, but also a high-level wizard, and has won many battles. He has accumulated great prestige both in the magic world and in the hearts of ordinary people.

At the same time, he also has various knowledge brought from the earth, which can be used as a reference.

What does Danger have?

He lost Weilan, suffered a defeat, and had to pay a huge amount of compensation. If he doesn't do it well, he might die suddenly.

It's not that what Danger did is not in line with the historical trend, but it's too radical.

"Who cares? He asked for his own death, and it has nothing to do with me. I gave him the ten-ring amulet, which is already a fulfillment of the promise of Mother Nature."

Coming out of the underground laboratory, there is a layer of identity review.

The review is very strict, and a large number of high-level equipment developed by Rosen are used to ensure that state secrets are not leaked.

After all, the situation is much more complicated than before, and it is not too cautious.

It took more than half an hour for the Duke Rosen to successfully walk out of the underground laboratory.

He got on the electric carriage driven by Alia and drove on the slightly muddy suburban road.

After leaving the aircraft research center that looked like a large construction site, Rosen suddenly had an idea and immediately said, "Don't go back to the castle yet, go to the woods by the Swan Lake, yes, over there."

When he arrived at the edge of the woods, Rosen got off the car and said, "You wait here for me, I'm going to meet an old acquaintance in the woods."

The woods are Metasequoia forests, with tall trees and sparse grass. Walking a distance ahead, you will see Swan Lake, where the water and sky are one color, and the scenery is very beautiful.

Soon, Rosen followed the path in the forest to the Swan Lake.

After walking along the lakeside path for a while, there was one more person beside him.

With light blond curly hair, soft facial features full of maternal qualities, and a blue-white summer dress that was slightly different from the last time, she was none other than Mother Nature, Sigurarana.
