(PS1: Chuanggui will be released this month, but I guess I have to wait a few days to know the plot, and I have been working overtime a lot lately, so I continue to goo goo goo goo goo)

(PS2: The purple god's supersonic speed is the setting of Bigui's original work. It is the only supersonic speed in all known setting sets of Samlia)

After returning from the Special Agent Support Section, Ling did not get any more information about Arios, except that Tio promised to help her pay attention to the movements of the Wind Sword Master in the Guerrilla Association. Tio did have a good relationship with Xiao

I contacted him via Daoli Communication, but the news I received was that he was on a business trip.

After returning to Rozenberk's workshop with Fei, Ling temporarily put aside the matter of inquiring about the whereabouts of the missing persons.

In fact, Ling's own power also includes Pian Lin's future observation, and the pictures that appear in her mind from time to time do not have any special warning information for her. In other words, there is no need to worry about their lives.

.They are all quite powerful people, and they will naturally appear when the time comes. And even if something happens, she is not without insurance. The day when the sleeping beauty in Ling's own bedroom wakes up is getting closer and closer.

After calling Fei to do the security work outside, Ling put on the formal clothes she wore when she appeared as a scholar, and then activated the star code, transferring not only her consciousness but also her body into the stars.

"Ken Parela, I'm troubling you for this 'observation'. Everyone has already arrived. And... even the 'Tribulation Flame' who hasn't been seen above for a long time is here. I have always contacted you through letters to ask for your advice.

"

Ling looked around and saw that almost everyone to whom she had sent invitations was present. Even some who did not expect them to come seemed to have sent agents.

"The place we are going to next is the 'Factory' on the border of the Republic. I have obtained the collective teleportation permission from the 'Limbus Forging Workshop'."

"Hmph, what you are going to test is a very interesting thing, isn't it? I'm just curious about what kind of world there is outside the 'shackles' of cognition."

It's rare for Markbon to show interest in things other than fighting.

There were three executors present, Ling, Ken Parela, and Mark Bon. Originally, Levi had also made an appointment, and he was the best test pilot. However, he could not be contacted for the time being, so Ling had to go on her own.

.

There are also three apostles - Vita in the second column, Wiseman in the third column, and Novatis in the sixth column.

Originally, Ling also invited the seventh sister, but she seemed to be busy doing something, so she asked Du Barry to join in on her behalf. Only Du Barry was present among the trio of Iron Machine Team.

After imitating the power of the Ring of Radiance and activating the collective teleportation, the seven people appeared in the desert area at the southern end of the Kalvad Republic, which was marked as an uninhabited area on the map.

Because of the extremely harsh environment, even locals from nearby countries rarely come to explore this desert. In fact, this place was opened by the association more than ten years ago as a manufacturing plant for large-scale combat weapons. Today's event is held here

What was being tested was the acceleration limit of the purple magic machine. This test was based on a series of aerodynamic papers published by Ling a few years ago, and was also based on the continuous improvement of the turbofan model she proposed.

Before several of Ling's aircraft were experimented in Leinfort, all flights were achieved by relying on anti-gravity magic. However, the speed of flight accomplished by magic or guidance magic is really not flattering. Even at present, all

The continent's most advanced Elsaiyu has a speed of only 3,500 cels per hour, less than one-third of the speed of sound.

But the Purple God Machine uses a completely different technology. Instead of relying on anti-gravity, it uses a pressurized turbofan that is closer to earth technology to fly into the sky.

It has been five years since Ling built the first turbofan in Qiyao Calendar 1199. For most people, they only know that this thing is a new engine, but it has neither been applied to guided vehicles nor to

The guidance airship has been ignored by people. But the association has never ignored this powerful force. After five years of continuous development by Dr. Novatis, the manager of the Thirteenth Workshop, it has achieved what Ling originally thought was impossible.

The painting style that will appear in Samlia.

The reason for this urgency is, of course, because the automatic weapons produced by the association in the past have been repeatedly frustrated in the Empire and the Republic in recent years. During the Libel mutation two years ago, the Kingdom of Libel also showed strong air force strength. Although

It didn't cause any real trouble to the association, but it also made the Sixth Pillar a little more vigilant.

"Military airships are usually the first team involved in conflicts, so arriving faster will give us more advantages on the battlefield." I saw that there are still people who are a little confused about this experiment, such as

Vita, Dubarry, and Dr. Novatis continued to explain, "A faster aircraft means a greater advantage. It fires at lightning speed and evacuates quickly after completing the attack target. Just imagine that scene."

"Escape with one blow? This is the nomadic fighting method of Nolde." Du Barry quickly thought of what Dr. Novatis said.

"Is it the guerrilla warfare used by Emperor Drakels two hundred and fifty years ago in the empire...I heard from the elders that there were only a dozen Nordic warriors when the army was first launched." Vita nodded.

"Actually, when the master entered the war, the power of the lion-hearted emperor had grown, and there was no need to use this fighting method. In the end, the decisive battle was still a contest of hard power." Du Barry said about himself.

Known information.

"Actually, twelve years ago, Cassius Bright of the Liber Kingdom used an airship to forcefully land on the empire stronghold with a small number of experts to carry out beheading tactics for the same reason. In short, soldiers are expensive and fast. Everyone here should be able to understand.

"

After the general outline is introduced in the sixth column, it is time for Ling, the actual producer, to explain to everyone.

"Because of the turbofan, the thrust of the aircraft has been greatly increased, reaching speeds that were originally impossible. Although currently the fastest aircraft in the world on the surface is still the White Wing Elseyu of the Liber Kingdom.

But our association has actually built many test aircraft that are much faster than it. When the airship flies at a lower speed, the sound of the main engine of the old guided airship - usually a large propeller - will spread in all directions.

For example, everyone should have been on board the "Red Ark" Grolias of our association. But for a unit with a turbofan as the main engine, when they continue to accelerate under huge thrust, they can reach 1,000 rpm.

At this moment, the sound waves will gather at the front of the aircraft. This phenomenon, which we call the sound barrier, will slow down the aircraft."

"Can you explain it more simply? After all, I think there are only three people here who can keep up with you." Vita interrupted Ling and asked her to speak more simply.

Ling was stunned for a moment, looked around, saw the frowning Du Barry and nodded.

In order to make it easier for others to understand, Ling picked a stone that looked about as tall as a person, then, standing a hundred moments away from the stone, she waved it in the air at high speed.

With a loud explosion, it was blown to pieces by the shock wave.

"Huh?" "Huh?"

Macbon and Du Barry made surprised sounds at the same time, but the reasons for their surprise were somewhat different.

"What kind of magical boxing technique is this? I've never seen you use it before. Ling, you didn't use fighting spirit, did you? How did you do it!?" Du Barry's attention was of course on the broken stone.

"The Heaven and Earth Returning Palm of the Tai Dou style is the secret inheritance of my cultivation. It will be more powerful if you use fighting energy, but it is not intuitive, and it will make people mistakenly think that it is the power of fighting energy, so it is useless on purpose." Ling did not hide it.

, explained it to Du Barry.

But the focus of Markbon's attention was different. He did not pay attention to the shock wave generated by the punch, but paid attention to what Ling herself showed him.

"Interesting, the one that was in front of your fist and blocked your punch was the sound barrier you mentioned, right?"

"Yes, I think you can definitely see the 'Tribulation Flame' clearly. So I think it is most convenient to demonstrate like this."

"Is this the 'shackles' that people haven't realized yet?"

"Of course not. The special bullets of some sniper-type guided guns can already break through the sound barrier, so this has not been considered a problem in the continent of Samlia."

Ling explained while leading everyone to the completed Purple God Machine.

"The sound barrier seems to be the limit of the speed that ordinary objects can reach, but in fact it is not. The muzzle velocity of some sniper rifles produced by Linefort or Black Works has broken through the sound barrier, which proves that as long as there is enough power,

, a huge aircraft can also forcefully pass through this boundary." Ling herself barely tried the feeling of physical supersonic speed last year, but she was quickly blocked by the subsequent aerodynamic heating phenomenon, if not

The premonition of crisis forced her to stop; she had been burned to ashes.

"As long as there is strong enough power, the front end of the aircraft is enough to smash air molecules and create a big disturbance. This is a sonic boom. You can think of it like applause. So in a short period of time, there is a hole in the sky, and when the aircraft

When it passes through it, the air collapses behind it, making a banging sound. This is the roar we will hear next - it is different from the loud noise of the guided airship."

"It's different from ordinary aircraft?" As a celebrity of the Imperial Capital Opera House, Vita also often makes guided airships.

"Yes, this involves some aerodynamics. If you want to understand this aspect, you can start with my lecture notes for introductory reading. Among the three divine machines in the world, only the purple machine does not use a force guide similar to Patil Matil.

This is also the reason for the shield system. Compared with the tip shape, a large force-guided shield will encounter double the air resistance. We imitate the principle of a sniper warhead and use the tip to tear open the wall of air during supersonic flight.

During the flight, the Purple God Machine will drag a cone-shaped sound wave behind it. When it flies over, you can hear the roar on the ground."

That’s it for the preliminary explanation. Then comes the test flight.

Although the three divine machines are all designed as fully automatic weapons that can operate independently, according to the preference of Dr. Novartis of the Sixth Pillar, the operating space is not equipped through phase transfer - just like the riding god, but

It has a built-in cockpit, similar to a mecha soldier.

In the not-so-small cockpit, Ling tapped the keyboard at super high speed, and the Purple God machine immediately switched to the idle cruise mode - its appearance was closer to the plane in Ling's memory of her previous life, rather than the one of Samlia.

Guided airship.

After takeoff, a large amount of air was sucked in from the front of the turbine, and then compressed by the blades to increase the pressure. At the same time, the formation array inscriptions in the booster box were lit up one by one, and the working fluid synthesized by alchemy was ejected.

When it enters the compressed air, when it starts to burn, the gas expands. Under extreme pressure, the gas is ejected from behind the turbine, producing an unparalleled thrust. Only Ling can physically push this huge force.

withstand the acceleration.

In the end, the Zishen machine did not use a more efficient and energy-saving turbofan engine, but a relatively primitive turbojet engine.

The difference between the two is that the turbofan adds a small speed to a large amount of air, while the turbojet adds a large speed to a small amount of air.

The core power source of the guidance force carried by the Zishen Machine is the same model as that of Patil Matil, which is enough to support high-intensity combat needs that last for several years. There is so much guidance energy that it can’t be used up, so there is no need to consider energy conservation in its design.

, this is a super benefit that aviation designers on earth will never be able to experience. Of course, Ling chose a simple, rough and powerful way to achieve miracles to complete this first supersonic aircraft in the Samlian continent.

The thing that Ling had been asking Markbon for advice through correspondence before was about the mystery of combustion.

To achieve supersonic flight, what is needed is not wind magic, but fire magic. The essence of a vortex is a continuous explosion. Although Ling herself knows a little bit about fire magic, it is not as good as Markbon.

This super master has completed the divine flame. The divine flame is not the black magic fire of external principles, but the purest original fire in the continent of Samlia.

Even Vita, who came from the Familiar of Fire, had to admit that Macbon was proficient in this way. When it came to playing with fire, no one in Samlia could match him.

The formation formation etched inside the vortex is mostly due to the work of flame mentor Macbon and Maria Bell, who is not present at the moment.

The huge sonic boom swept across the earth. Although it was just a small track in the sky, the people below were still extremely excited to see it. It was more than three times faster than El Saiyu, and it was still accelerating. Under Ling's

As long as her body could bear it, she kept testing the limits of the Koldarite steel that made up the Purple God Machine. It wasn't until a heart-wrenching metallic sound suddenly appeared that she immediately stopped pressurizing, and then went to the ground.

Quickly swooping down.

"How about it? Is it okay?"

Dr. Novartis looked at Ling, her face turned pale and flushed for a while, but he was more concerned about the experimental data.
To be continued...
