Start with Island Lord

In the mountains, there is a secret aircraft research base.

There is a semicircular mountain passage inside the base. If you follow the passage all the way forward, you will enter a secret and narrow valley.

One end of the valley is closed, and the other end is a steep cliff. There is a 25-meter-wide and 500-meter-long tempered yellow clay avenue built in the valley.

‘Woo~~Woo~’

Amidst the low hum of the motor, a special electric vehicle towed a flatbed truck and slowly drove out of the underground passage.

There is a strange blunt triangular creation about 20 meters long and 10 meters wide placed on the flatbed truck.

There is a circular hole at the tail of this creature, and a transparent bulge with smooth lines near the obtuse head.

At first glance, it looks a bit like a flying-wing bomber from Earth.

It can be seen that there are two slightly narrow seats in the bulge, one in front and one in the back, with two people sitting on them.

Rosen was in the front seat, and flying master Neferoniya was in the back seat.

This strange thing is naturally the rune flying machine built by Rosen.

Much like an airplane, but instead of propellers, the power is jet-like.

It is said to be jet-like because it uses a very different method from jet engines on Earth to obtain jet airflow, and does not have complex and precise vortex blades and rotating shafts.

There are pros and cons to this.

The disadvantage is that the thrust is greatly limited, and sufficient lift can only be obtained by increasing the airfoil, and the top speed is naturally greatly limited.

There is a common sense here that for flight, thrust and airfoil are inversely proportional. The greater the thrust, the smaller the airfoil area. To a certain extent, even a single person can fly into the sky.

The advantage is that the structure is simple, the difficulty of manufacturing is greatly reduced, and the consumption of mana is also reduced to a minimum.

In the cockpit, Rosen was carefully checking every fine component on this small rune plane through small detection spells to ensure nothing went wrong.

As the plane continued to approach the exit of the aisle, Neferoniya seemed a little nervous and her breathing became slightly heavier.

Rosen smiled and said, "Niya, are you scared?"

Roferoniya did not deny this: "This is the first time I have flown without wings, and as soon as I think about the fact that the top speed of this thing is more than twice as fast as mine, I feel a little panicked."

In weak wind weather, her top flight speed is about 180 kilometers per hour. Rosenruo transforms into a steel dragon body and sprints with all his strength, which is slightly faster than her and can reach 200 kilometers per hour.

But this blunt triangular rune aircraft with an almost completely fused wing body is designed to have a cruising speed of 380 kilometers per hour and a top speed of 500 kilometers per hour.

For airplanes, this speed is not very fast. Earth's propeller planes can reach or even surpass it, but it is already the limit of the island's capabilities under current conditions.

It is also a super-speed that is beyond the reach of ordinary people in this world.

Rosen smiled and comforted: "Don't worry, the magic weapon has enough safety settings. Even if it crashes straight into the mountain, we won't die."

"Although I say that, you made all the things. I know nothing about it, so of course I still feel guilty."

"That's right. Then I will fly slower at the beginning, which is almost the same as our flight speed. Then I will slowly speed up."

"good."

At this time, the plane was completely towed out of the mountain passage and turned onto the yellow clay road in the valley.

After waiting for the nose of the plane to adjust, Rosen raised his hand to signal irrelevant personnel to stay away from Valley Avenue.

After waiting for a while and confirming that everyone had hid in a safe area, Rosen raised his hand and pressed the valve, and the gas installed in the compressed gas bottle was immediately poured into the normal-pressure rune combustion chamber.

In less than a few seconds, Rosen ignited the air mixture in the combustion chamber.

‘Boom~~~Hu~~~’

The initial mixture of air created a weak deflagration, but soon the combustion stabilized.

"This thing is really scary."

Neferonia wiped the sweat from her forehead. If it weren't for the ice amulet she was wearing, or if she hadn't lost a bet while playing games on the beach, she wouldn't have sat on this thing.

Rosen chuckled, thought slightly, and began to pour mana into the wind conversion circle.

With the activation of the magic circle, the flame power in the combustion chamber is transferred to the airflow in the jet chamber.

‘Hoo~~’

The air jet chamber is activated, the front end airway begins to inhale violently, and the rear end airflow is violently ejected backward.

The jet of air is very strange. It is almost pure and transparent, without any color of temperature. It is like a directional high-speed jet of heat wave.

The rune plane trembled slightly and began to accelerate forward.

The 500-meter acceleration runway is not long, but it is enough for the rune plane to take off.

After waiting for the speed to be almost the same, Rosen pulled the control stick, the back of the flying wing slightly turned down, and pulled the nose of the aircraft up.

The fuselage shook slightly and rose from the ground at a small angle.

"It's really flying!" Neferonia exclaimed in low voice.

Did she know that this thing weighed five tons?

She did not forget her mission, and immediately began to carefully experience the changes in the airflow around the aircraft, and she immediately clicked her tongue in amazement:

"So far, the wind control is very smooth, almost sliding forward in the airflow."

Rosen didn't say anything. He was closely monitoring the plane's flight status.

There are mainly three important parameters.

One is the gas balance. The second is to change the operating state of the array.

The third, and most important, is the operating status of the flying puppet.

This flying puppet is the key to the aircraft getting into the sky.

If there is no such thing to assist, and it is purely controlled by the mage, the difficulty of flying will increase to an incredible level, and few mages will be able to fly.

It is driven by the puppet's psychic energy, which is stored in a special psychic lattice.

The psychic energy will be filled in advance before flying to save the flying mage's mana.

According to the design, the psychic energy in the psychic lattice can support the puppet's operation for about 3 hours.

At present, everything is normal.

Soon, the rune plane rose to an altitude of about 500 meters, and the speed increased to 200 kilometers per hour.

The fuselage is still very stable, and because of the cockpit glass and good sound insulation measures, the cabin is still quite quiet.

Neferoniya commented: "Well~ I now feel its benefits, it saves effort and is quiet. If I fly by myself, I can hardly open my eyes now."

Rosen reminded: "Do you feel any shortcomings?"

All his flying knowledge comes from the two Banshee Queens, and so does Lai Fu.

From their point of view, this aircraft is already the best under the current manufacturing level.

But it cannot be guaranteed to be the best in Neferoniya's eyes.

Neferoniya calmed down and carefully felt the changes in the wind force around the fuselage:

"I feel some flaws, which is the main source of vibration of the fuselage, but at this speed, the problem is not big."

"Try to speed up."

Rosen slowly accelerated.

The combustion in the combustion chamber became more and more violent, the conversion array consumed more and more mana, the vibration of the fuselage became more and more serious, and the posture became a little unstable.

But the fuselage uses the newly developed hardened pure water material and adopts a variety of reinforced structural designs, so it can still withstand it.

At this time, the aircraft reached a cruising speed of 350 kilometers per hour.

"There are three minor defects, one is a manufacturing defect, and the other two should be structural defects."

The noise in the cabin was already very loud, and Neferoniya had to shout loudly.

Rosen also roughly felt it.

The plane is only 1,000 meters high. Looking down from here, you can see that the forest below is flying past at a very fast speed, and seabirds are flying around the fuselage from time to time, and there is a risk of bird strikes at any time.

Although according to the design strength, a bird strike at a speed of 350 kilometers per hour should not penetrate the cockpit, but you have to be prepared for the worst.

So he immediately turned on the special lightning bird-repelling sound wave.

Neferoniya asked, "Do you want to speed up?"

Rosen did not answer. He carefully felt the fuselage structure and felt that he could still hold on, so he said, "I'll speed up a bit."

He increased the burning intensity again and raised it to the designed maximum speed of 500.

The wind outside the cockpit began to roar, and the fuselage seemed to dance in the airflow, as if it could flip over from the sky at any time.

Rosen's mana was also consumed at an accelerated rate.

Neferoniya calmed down instead. She held the fixed handle tightly and carefully sensed the surrounding airflow in the chaos.

Then, as expected, several minor flaws were found.

It has no effect at low speed, but as the speed increases, it gradually emerges and becomes a safety hazard.

"Rosen, it's almost done. If we fly for a while longer, this thing will fall apart."

Rosen also had a similar feeling. He began to slow down slowly and controlled the plane to turn back to the secret valley.

'Hu~~~~~~Zi~~'

The plane landed smoothly on the avenue.

"How does it feel?"

Neferniloya has basically adapted to it and praised sincerely: "This thing is really fast, just like lightning."

She calmed down for a while, then opened the cockpit, climbed onto the fuselage, and took a charcoal pencil to mark various parts of the fuselage.

"The circle is a big problem, the cross is a small problem, and the cross circle is a problem that occurs at extreme speed. There are 8 places in total, but I don't know how to modify it specifically, after all, I have never flown so fast."

"We have to try it again and again."

Rosen felt his mana, which was still 90%, and the combustion gas cylinders in the plane were still sufficient, so he said: "Then change it again and again."

The parts that need to be modified are not large, and the range of modification is also small. Transfiguration can be used to process directly, so it is modified on the spot.

After the modification, it will be tested directly in the sky.

In the following time, the two tried it again and again, and fine-tuned it bit by bit.

From morning to night, if the modification is not completed in one day, it will continue the next day.

It lasted for five days. After dozens of experiments, the appearance of the aircraft has basically not changed from five days ago, but the details have been adjusted very precisely.

These adjustments may seem insignificant, but they are the true essence of this rune aircraft, and they are also the biggest threshold for others to imitate.

At this moment, it can finally run stably at a maximum speed of 500 kilometers.

After taking to the sky again, the rune plane passed quickly in the sky like a flash of light, and advanced 140 meters in the blink of an eye.

The posture was particularly stable, the airflow was extremely stable, and the fuel and mana consumption were much less than the first version.

In the back seat, Nefiniloya felt the roaring wind outside the cabin, while experiencing the tranquility and peace of the airflow inside the cabin.

There was only a thin layer of transparent glass between extreme movement and extreme stillness.

Turning around, there were clouds flying backwards around him, and looking down, there was the somewhat smaller Sturgeon Island.

Unknowingly, they had reached an altitude of 6,000 meters, which was also the ceiling of this rune plane.

She couldn't help but sigh: "The magic of the new era is really great!"

This is a level she could never reach no matter how hard she flew, and she didn't dare to think about it in her dreams.

Rosen shook his head: "It's not great enough, there is still endless potential for improvement, especially since the true secret of the magic ring is still unknown."

"You are really unsatisfied, but this is probably the driving force for the advancement of magic."

After experiencing it carefully, she asked: "How long can your magic last at the top speed?"

"About 4 hours. If it is a high-level mage, it is estimated that it can only last for ten minutes, but if it is at cruising speed, the high-level mage can last for 1 hour."

Obviously, although a high-level mage can fly it into the sky, he can't fly for long, and the battle time will be very hasty.

The current solution is to equip two high-level mages, and then use mana recovery potions as an aid to carry out relay control.

Neferoniya thought about it carefully: "That means it can travel back and forth within more than 400 kilometers, and can cover the Shire County."

Rosen nodded: "Almost, but the range is still too short."

In this regard, the motor propeller aircraft currently under development can fly much farther because it involves fewer conversion arrays and has low dependence on mana.

But the mechanical structure of the motor propeller aircraft is much more complex and precise, and it cannot be built in a short time, so it can't catch up with this Weilan civil war.

He secretly thought: "Let's use it first, and wait until the mechanical manufacturing level of the island reaches a certain level, and then find a way to improve it."

Pull the nose over and land back at the aircraft base again.

After getting off the plane, he found the senior wizard in charge of aircraft production, a khal named Todd:

"Just produce according to this standard, there is not much time, and as many as you can build."

Rosen estimated that he could make about 10.

Todd nodded and asked again: "Lord, do you want to install weapons?"

"Of course. One part is equipped with spiritual weapons, and the other part is equipped with master lightning crossbows."

Psychic weapons are made of advanced lightning lattices and spiritual meteorites. One is a 'stun bomb' and the other is a 'deterrent bomb'.

The island is strong in making lightning lattices. The lattices are small in size and large in capacity.

Psychic meteorites have also been artificially synthesized, but the output is very small. Currently, only two can be equipped.

If we really want to fight a large-scale battlefield, this amount of air force is not enough. It can only be used for deterrence for the time being.

Todd asked again: "Lord, should we give it a name?"

Rosen had already thought about it: "The one carrying spiritual magic weapons will be called the Roarer. The one carrying the master lightning crossbow will be called Thunderbolt."

This rune plane is naturally Rosen's second trump card to deal with the Southern Alliance.

At this time, there is still a month and a half before the Southern Alliance goes north.

He should also prepare the last hand.
