Underground laboratory.

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

"That's right. There is no perfect invisibility in the world. Defeating the enemy by using invisibility is a bit of a gamble."

"Both the ability to resist and break spells is insufficient. If it encounters a super-large-scale barrier supported by a large-scale conversion array, such as a lightning barrier, it may fail directly."

"Thirty kilometers is a long range, but it would be better if it could be farther."

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

“.”

After a bunch of hindsight-like analyses, the mages came to a unanimous conclusion.

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

It's because of the right tactics and unexpected design ideas.

Once it is used many times and the opponent understands its performance, they will have a lot of defensive measures.

Rosen fully acknowledges these shortcomings, which is why he convened the discussion.

He clapped his hands and concluded.

"No matter what, the design concept of this weapon is groundbreaking, its combat effectiveness is amazing, and it can also minimize casualties among soldiers."

"At the same time, we must also admit that there are no perfect weapons 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 stand aside. In future research, I will always participate in it and contribute my wisdom and talents to protect Weilan."

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

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

As a result, many wind mages who knew nothing about building flying machines and were feeling insecure now had a backbone.

Everyone started clapping.

When the crowd quieted down a bit, Rosen pointed out several young mages in the crowd.

Five people came out.

Three of them were previously at the Aircraft Research Base on Sturgeon Island.

There are two new wizards named Weilan who graduated from the Silver Moon Academy of Higher Magic in Kao.

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

At the same time, they were all of common origin.

"Come with me, we can talk alone."

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

The five magicians followed immediately.

Rosen took the five people and toured the research base while chatting with them about his ideas about the new unmanned aircraft.

"What you just discussed 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 magical instrument, even just a little bit, right?"

The five wizards nodded.

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

At this time, I have clearly understood the basic principles of unmanned magic tools.

But the more I understand, the more difficult it becomes to improve.

When talking about it, everyone was very relaxed. With just a touch of lips, everyone could come up with a lot of truths.

But when you actually start to do it, you will find that there are unattainable barriers everywhere, which makes people feel desperate and have no way out.

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

Most people can only stand by the ditch and watch the fun, while those who can actually cross it will be the protagonists on the world stage.

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

The respectable position and decent income allowed him to live a respectable life in the Silvermoon City of Khal.

The reason why he dropped everything and returned to Veran was because he admired the Duke's achievements in magic.

And he was indeed highly 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 to you, it's like a beginner meeting a master. I didn't know that high-speed airflow has so many special properties."

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

He smiled and said, "Sir, your research on the temperature and pressure properties of gases is also extremely valuable. They are two sides of the same coin of gas properties, and there is no difference between the two."

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

Belladrin immediately said: "My idea is the same as that of large manned aircraft, using the reverse thrust of ultra-high-speed airflow to obtain power. But the way to achieve it is different."

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

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

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

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

Rosen was not in a hurry. He raised his hand and told others to stop talking and think quietly.

After a few minutes, Belladrin suddenly said, "Duke, I suddenly thought that maybe we can use dephlogisticated water and phlogisticated water to burn a mixture instead of gas tanks, and then directly spray out the high-temperature steam after burning. This will definitely generate a huge amount of power."

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

This is awesome stuff.

Rosen nodded repeatedly after hearing this: "What a great idea!"

"If it succeeds, not only will the power of drones be solved, but maybe the endurance problem can also be solved."

"I think so too!"

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

"As you command, Your Excellency the Duke."

Belladlin was very excited because this wonderful new idea opened up his mind and a lot of new ideas suddenly flooded into his mind.

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

Belladon ran away.

Rosen continued, "Master Humer, the Gyro Balance Rune is a very subtle and powerful piece of knowledge. It all depends on you to improve it."

Master Xiumer comes from an island. He is a taciturn but very reliable wizard.

Hearing this, he nodded: "Leave it to me, Lord."

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

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

Apparently, his advice was very useful, helping the three mages find a clear direction forward and greatly dispelling their confusion.

Finally, Rosen encouraged: "In the foreseeable future, this type of unmanned explosive aircraft will be the core weapon for protecting islands."

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

"The safety of Veran, and the fate of Veran's thirty million citizens, rests on your shoulders."

The four mages were all born as commoners, and the good core positions had always been monopolized by the nobles.

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

For a moment, I felt heavy-hearted, but also felt an incomparable sense of honor and mission.

Unconsciously, he clenched his fists and pursed his lips, as if trying to snatch the treasure from the Creator's hands.

This is the spirit that Rosen needs.

He raised his hand and gently patted the mage on the shoulder: "Go forward, young people~"

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

The four mages were obviously much older than him, but they all felt like young men who had just graduated from the academy. They immediately felt trusted and valued, and their blood began to boil unconsciously.

They are like ponies encouraged by their elders and throw themselves into their work with great enthusiasm.

Rosen watched 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 mischievous ones."

This first generation of citizens had not yet seen the world and naturally had a Puritan and ascetic spiritual background.

He is the most down-to-earth and hard-working person. As long as he is used well, Weilan's national strength will surge forward like a train.

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

I thought of Dange on the other side of the sea again and sighed inwardly.

"This guy is powerful, but he slaughtered all the nobles in the country in one go, 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 huge 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's Danger?

Not only did they lose Weilan and suffer a defeat, they also had to pay a huge amount of compensation. If they were not careful, they would probably die suddenly.

It’s not that what Dange did was out of line with the historical trend, but it was too radical.

"Who cares? He brought his own death upon himself. It has nothing to do with me. I gave him the Ten-Ring Amulet, which is considered to be fulfilling the promise made to Mother Nature."

After coming out of the underground laboratory, there is a series of identity checks.

The review is very strict and uses a large number of high-efficiency equipment developed by Lawson, with the aim of ensuring that state secrets are not leaked.

After all, the situation is much more complicated now than before, so it’s never too cautious.

It was more than half an hour later that the Duke Rosen successfully walked out of the underground laboratory.

We 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. Let's go to the woods by Swan Lake. Yes, that's right there."

When they reached the edge of the woods, Rosen got out of the car and said, "Wait for me here. I'm going to meet an old acquaintance in the woods."

The woods are Metasequoia forests with tall trees and sparse grass. Walking a little further ahead is Swan Lake where the water and sky merge into one. The scenery is extremely beautiful.

Soon, Rosen followed the forest path and arrived at the Swan Lake.

After walking for a while along the lakeside path, there was another person next to me.

She had light blonde curly hair, soft facial features that were full of maternal charm, and was wearing a blue-white summer dress that was slightly different in style from the last time. She was none other than Mother Nature, Siegrelana.
