Chapter 115 One One Four: Nine Heavens Gangfeng Octopus

(Ask for a subscription, ask for a monthly pass!)
……

Twenty examiners, "swish swish" each showing their magical powers, jumped onto the star tower suspended in the sky.

This Xingcha, which looks like a long whale, is called Kunpeng Xingcha, and it is a customized version of Kunpeng City.

It is more than [-] meters long, and it is only a human-level Xingcha.

Two huge wings spread out from both sides, like clouds that line the sky.

It looks like a wing, but it is actually a Sunda sail.

The brilliance of rune arrays flashed on the wings, and suddenly there were pieces of armor similar to fish scales, covering the entire wings.

The nails vibrated with the wind next to each other, as if they were really the feathers of a pair of huge roc wings, absorbing the power of the sunda wind, and at the same time, they can continue to escort the speed of Xingcha.

After Xingcha flew high into the sky, a ray of golden light pierced the void of hundreds of millions of feet from the horizon, and the earth continued to shrink under his feet, which was really beautiful.

A translucent shield covers the deck.

Kunpeng flicked his long tail, and flew out bathed in the rays of light.

The speed was getting faster and faster, and then there was a sudden explosion in the ear, breaking through the sound barrier.

Li Suian felt that he had slight tinnitus symptoms.

It only takes a little movement of the body's qi and blood to offset this obstacle.

Xingcha's wings broke through the thick atmosphere of heaven and earth, and a large amount of white mist rose from the tail of the long whale, forming a huge sonic boom cloud.

Then the tail fin flashed, and Li Suian saw the brilliance of the formation runes, and he recognized one of the key basic runes, which was used for noise reduction and was often used in basic sound-proof formations.

Then the sonic boom cloud of the tail wing immediately diminished at a speed visible to the naked eye.

"A single sound-absorbing array can offset most of the obstacles of the sonic boom cloud?!"

"What's the principle?"

Li Suian was amazed, and couldn't help becoming more interested in the study of Taoism.

Humans on the earth have science, and humans in the mountains and seas have metaphysics.

In essence, it is an exploration of the rules of heaven and earth.

I just don’t know, how much of the truth in it have in common?
However, basic physics knowledge should still be common here.

Li Suian walked to the edge of the deck, looked down at the ground, leaned out mentally, quickly compared the distance of the ground and the time velocity, and calculated the speed of Kunpeng Xingcha at this time, 300m/s, 600m/s, 900m/s.

He doesn't know what the Mach number is in this world, after all, it has not been accurately calculated

At this time, the flight resistance is already very strong, and it can be clearly seen that the upper armor of the wings vibrates violently.

Calculated according to the speed at which the sound barrier appeared just now, 300m/s is probably the Mach speed at this altitude and atmospheric pressure at this time.

Use this as standard.

Then the speed at this time has exceeded the maximum flight speed of the J-[-].

That is, Mach 2.5, the fastest it can fly is 850 meters per second, which is equivalent to flying 3060 kilometers per hour (on Earth).

Li Suian once tested his own running speed, running on the ground purely with the agility of "Flying with the Wind".

The fastest can approach 50 m/s, which is equivalent to a speed of 180 kilometers per hour.

The pressure at that time was already extremely huge, almost running against a typhoon of level 15, and the pressure on the body was also extremely strong.You should know that the maximum wind speed near the center of the super typhoon is about 50m/s.

And once Xingcha reaches this speed, it is already flying at supersonic speed.

Next, even if it is only to increase the flight speed by one meter per second, it will require an extremely large power output.

He immediately looked to the wings.

as predicted.

Stripes of blue light shone on the wings.

That is obviously exerting a greater power.

Mach 3, Mach 4, and finally stabilized.

Speeds between Mach 1 and Mach 5 are called supersonic; speeds above Mach 5 are called hypersonic.

In the end, Xingcha could fly without breaking through supersonic speed.

Li Suian stretched out a finger and stuck it in the air with some saliva, obviously feeling the temperature rise.

Walking to the edge, I curiously reached out to touch the shield.

"Boom~"

A halo spread from the point where the fingers touched, to the surroundings.

He didn't expect such a violent sound to reverberate.

And everyone who was meditating on the deck all turned their eyes to him.

"What are you doing?"

Qianhu envoy Chen Gong's voice suddenly sounded behind him.

Li Suian was startled, he hadn't noticed anyone approaching just now.

Turning around, he happened to meet the blood-eyed crow on Chen Gong's shoulder.

The crow tilted its head in a humane way, and looked Li Suian up and down.

His heart froze immediately, and he bowed and said, "My lord, I just want to test the temperature change of Xingcha when it breaks through the limit speed of sound."

Chen Gong's voice couldn't tell whether he was happy or not, and said, "Then have you ever measured it?"

Li Suian was silent for a few breaths, but still said: "...a little gain."

"Oh, let's talk about it. Anyway, the journey is still far away, and I don't mind listening to it."

Li Suian had no choice but to bite the bullet and said: "Just now when the speed of Xingcha broke through the speed of sound, a sound barrier appeared. When it was close to two and a half times the speed of sound, the temperature here rose significantly. The Xingfeng sail reacted violently, and the energy output of the rune array also increased. It continues to increase. After that, every time the speed breaks through a layer, the temperature continues to rise. Even if it is protected by a shield, it can still be clearly felt..."

"Did you just say the speed of sound? The sound barrier?"

Chen Gong suddenly interrupted him and asked a question.

Li Suian glanced at all the men and women on the deck, and even the guards, the lantern bearers and the night watchman, all looked at him.

Helpless, I had to explain the speed of the sound a little more.

"The essence of sound is just a kind of ripple (mechanical wave) propagating in the medium. The speed of propagation in water, air, and earth is different. Different media, temperatures, and pressure states have an impact on the propagation speed. Usually The performance is: the fastest in solids, the second in liquids, and the slowest in gases."

"There are many ways to test the propagation speed of sound. The speed of Xingcha exceeds the speed of sound transmission. If the sound cannot catch up, a sound barrier will naturally occur."

"I have never been in contact with Xingcha production, but I guess there should be a fixed standard. I set the speed of sound transmission in the atmosphere as the basic speed of sound."

(PS: The density of the atmosphere in the mountains and seas is bound to be different from that of the earth. Talking about Mach without talking about height is just playing hooligans. Mach is a unit of speed. Mach 1 is not always equal to 340 m/s.)
Chen Gong was very surprised, and thoughtfully said: "Since the speed of voice can't catch up, why can I still talk?"

"My lord, this is a relative situation. The specific principle, ... still needs to be studied." He didn't want to explain the theory of relativity.

"Go on. What does this have to do with the temperature you tested the shield for?"

"Yes, my lord."

"The speed of sound propagation is different in different media, temperature and pressure states. The greater the density of the medium and the higher the temperature, the faster the speed of sound propagation. And the flight obstacles of the stars also include sound, air, and frictional heat."

"The higher the altitude, the lower the temperature and the thinner the atmospheric density."

"I think, if Xingcha can fly to a higher area, the speed may be faster."

Hearing this, Chen Gong took a serious look at him and said, "Did you know that if you go up, you will encounter Jiutiangangfeng? The wind spirits and wind monsters in Jiutiangangfeng will not be polite to you."

Walter?

Li Suian raised his head, the sky was clear, with only a few white clouds, where did the wind from the nine heavens come from?
This obviously violated his blind spot of knowledge.

At the same time, he also realized that many of his knowledge on the earth cannot be blindly copied.

Maybe he is very knowledgeable in some aspects, but in terms of seeking truth from facts and studying the actual situation, I am afraid that even Hu Boji is not as good as him.

When he didn't know how to answer, Chen Gong said again: "However, there should be no danger in the sky, you can try."

After all, he waved his hand behind him.

Immediately, someone shouted into Xingcha's cockpit: "Raise the altitude, ten thousand zhang!"

"Yes."

Ang Ang Ang~
Kunpeng Xingcha suddenly made a strange sound, which was really like the neighing of a long whale.

The huge halberd on Xingcha's head pierced the sky, and he raised his head suddenly.

The bodies of everyone on the deck tilted suddenly, and they almost lost their footing.Immediately with a heavy drop, he stood firmly.

But Li Suian held on to the masts and reins on both sides very carefully.

Chen Gong put his hands behind his back, looked up at the sky, and remained motionless.

Wanzhang is an altitude of 3000 meters.

According to Earth standards, this should be the troposphere.

Clouds, rain, snow, hail, etc. all occur in this layer.

Even in this world, it is a rare experience to be able to reach this height now, Li Suian immediately focused on observing.

At the same time looking at the distant sky, he wanted to see the edge of the planet.

It's a pity to watch a lonely.

Even at a height of ten thousand feet, they are still flying among the mountains, and they can't even see some higher mountain peaks. How can they see the edge of the planet.

This world is much bigger than imagined.

But it can still be roughly judged that the Mountain Sea Realm is not some strange continent floating in the universe, but also an extremely huge elliptical sphere.

Therefore, it is impossible to dream of seeing the edge of the planet from a high altitude.

However, at this height, the tallest Optimus Prime iceberg in the north of the Canopy Mountains finally revealed the upper half of it from the clouds that lingered all year round.

It turned out that when you were basking in the sun, you could only look at the cloud-shrouded land from a distance, but it was only at the foot of the mountain.

The upper half of Optimus Prime is covered with glaciers, bathed in golden sunlight, forming a golden color, just like a holy mountain!
It is too huge, I don't know how many miles high it is.

Li Suian doubted that the peak of that mountain range would plunge straight into the universe.

"One day, I must climb that mountain."

Li Suian thought to himself.

The height of [-] zhang is not enough compared to large mountain peaks, but it is more than enough compared to those ordinary peaks on the earth.

Looking down from a high altitude, those mountain peaks are like low slopes at this time.

Quite a few people looked pale, their throats were throbbing, they panicked, their legs were even trembling, and they unconsciously walked towards the center of the deck, away from the edge of the star tower, afraid of falling.

In ancient times, the sky was a forbidden place for gods.

Today's human beings have repeatedly broken through the high-altitude restrictions, but are limited by the limitations of knowledge dissemination, and it is still only seen by a very small number of people.

"Acrophobia!"

Li Suian suppressed a smile, "Fortunately, I didn't."

He grasped the railing and looked into the distance.

The viewing effect here is amazing.

Looking around, there are more than a dozen peaks that cannot be seen nearby.

But at this altitude, the air pressure has further decreased, and the speed of Xingcha has further increased, about 1400m/s.

"Keep going up!"

Chen Gong was shocked and continued to speak.

"Yes!"

shouted from the cockpit behind him.

Li Suian was silent.

This mysterious envoy of Qianhu from the Ministry of Heaven looks calm on the face, but he is crazier than him on the inside.

Xingcha rose again, [-] zhang, [-] zhang, [-] zhang, and it was still rising until it reached [-] zhang.

"Om~"

Xingcha's speed suddenly soared.

He took a deep breath, and his heart beat a few times quickly, calming down the uncomfortable feeling of lack of oxygen.

Is it the stratosphere?
Why are there still mountains beside me?

On the earth, it has already entered the stratosphere, but in the mountain and sea boundary, it is still far away from the stratosphere.

The [-]-meter-long Xingcha flies between towering mountains like pillars of the sky, like a tiny sparrow.

The vision of the distant sky began to become blurred, as if the whole world was shrouded in a layer of dark yellow light.

However, it wasn't long before flying.

In the sky where there was nothing before, the wind suddenly became violent, and a layer of fiery red energy appeared on the protective cover.

Electricity began to flicker on Xingcha's wings.

"My lord, I've reached the limit, I can't go any higher."

One of the subordinates, Baihu, spoke up.

Chen Gong was a little bit unsatisfied, nodded, and was about to order to descend when something happened ahead of him.

I saw a translucent monster suddenly jumping down from high in the sky.

In terms of size alone, it is several hundred meters long, several times larger than Kunpeng Xingcha.

"Oops, it's the Nine Heavens Gangfeng Eight-Clawed Wind Monster!"

"decline!"

Without Chen Gong's orders, Baihu directly ordered.

Kunpeng Xingcha immediately fell ninety degrees down.

Everyone was a little panicked, they didn't care about being handsome, and they all looked for a place to catch them.

One lost his grip, and fell directly on the shield with a bang, and bounced back, clutching the deck in embarrassment.

But the wind monster with the eight-clawed wind was chasing after him, and charged straight down.

Kunpeng Xingcha quickly dodged in the air, narrowly dodging the tentacle attack several times.

Chen Gong just looked at the octopus wind monster, without any intention of making a move.

Xing Cha fled in embarrassment, and fell below ten thousand feet, the monster let out a roar unwillingly.

Endless storm-like wind blades spewed out from its mouth, hitting the protective cover, stirring up layers of energy debris that scattered like snowflakes.

The Xingcha continued to descend until it reached a height of five thousand feet, passing back and forth among the mountains. Seeing that it could not catch its prey, it reluctantly stopped chasing, swung its tentacles again, and flew up to the nine heavens.

Everyone breathed a sigh of relief in due course.

Chen Gong seemed to have gotten used to it long ago, and asked Li Suian, "Have you ever learned the way of formation?"

Li Suian said: "This subordinate is new to the formation, but he has no good teacher, so he can only figure it out by himself."

"Well~ After the assessment is completed, there will be a Department of Secrets that specializes in studying formations. You can think about it."

"Thank you for your advice."

"Ah."

Chen Gong just said one more word, and entered the cabin with his hands behind his back.

The rest of the people looked at Li Suian, and there seemed to be something in their eyes, but no one came up to chat.

Even if it is communication, it will not be too late to wait for the assessment to be settled.

Three hours later.

Xingcha flew steadily among the mountains.

The calm-looking Lord Qianhu no longer took any risks, and encountered no danger along the way. Even if there were occasional high-altitude raptors that jumped out occasionally, they were all like paper in front of Qianhu envoys, who were in the realm of Yugang. one strike.

Chen Gong didn't even show the attack of the soul magic technique, but the extreme speed and strength of his gestures made all the eyes on the deck glow with envy.

Finally arrived at the destination.

Yin wind tunnel.

It is one of the 72 secret realms in the Northland.

Located in the south of Optimus Prime Peak in the Tianpeng Mountains, it is connected to the cold atmosphere of the North Sea, and the wind is lingering all year round, and there are few people.

The full name of the North Icefield Road is the North Sea Icefield Road, which connects to the North Sea of ​​Darkness.

According to the legend, the Yinfeng Cave is the place where the Supreme Being of the Northern Darkness exiled the sinful spirits of the Northern Darkness.

Li Suian has read the Taoist scriptures, and there are many legends about the ancient Beiming Supreme.

When we arrived at the destination, there were still heavy guards here.

The Yinfeng Tunnel doesn't look very big from the outside, it's about a hundred feet wide, and it's composed of countless small wind holes.

Surrounded by rocky rocks and forests of ancient trees, there are many damaged ancient buildings outside the cave.

From time to time, some dilapidated and huge palace complexes, even Buddhist temples, Taoist temples, etc., all show that people have lived here.

The stars fell on the square.

Immediately someone greeted them and brought everyone to the stone platform outside Yinfeng Cave.

Everyone stood in the middle of the field and listened intently to Chen Gong's words: "Among warriors, those who have the qualifications of soul warriors are chosen one in a million."

"But among the soul fighters, there are also grades of aptitude. Among them, the first to third grades are high-grade aptitudes; the fourth to sixth grades are medium aptitudes; and the seventh to ninth grades are low-level aptitudes, depending on Divine Soul Seed."

"It is said that above the first grade, there are still top-grade spirit species. But this kind of legendary top-grade aptitude has not appeared for a long time since the Kuroshio came."

"There is a soul-testing stone here. Those who can test the aptitude of the soul can test the aptitude of the soul by sticking their hands on the stone."

"Before entering the Yinfeng Cave, everyone should test their aptitude first."

After Chen Gong finished speaking, he stroked the black crow and stopped talking.

Immediately there was a general who stepped forward and directed everyone to test their qualifications one by one.

The test stone has been touched countless times, and the surface is smooth and covered with starch.But it is still completely dark, as if it is connected with the whole mountain.

The military commander casually ordered one person, "You come first."

The person who was called first, named Hu Chao, asked seriously: "General, how do you test this aptitude? Is it just putting your hands on it? Is there anything that needs attention?"

"Press it with both hands, and if you have the aptitude of the soul, the soul-testing stone will glow. The brightness of the light is different, which means the difference in aptitude."

Hu Chao pressed his hands up according to his words, and immediately showed a blank expression on his face.

Everyone immediately widened their eyes and watched carefully.

I saw a dazzling purple light emitting from the originally dark stone, and the light became more and more intense.

Everyone also immediately discovered the mystery.

The brightness under the stone is divided like a grid.

After a while, I heard Hu Chao screaming suddenly, breaking free from the state of trance, and two bars of light lit up on the stone.

"This...is my aptitude good or bad?"

Hu Chao looked at the test results blankly.

　There will be more in a while!
