(An explanation of the 'gravitational' problem raised by the reader.)

Gravitational force/gravity, inversely proportional to the square of the radius. The farther an object is from the planet, the smaller the gravitational pull/gravity. However, the atmosphere is only a few tens of kilometers high, and the orbit of the near-Earth satellite is at an altitude of 500 kilometers or even lower, which is not much different from the Earth's radius of 6,371 kilometers.

The gravitational force in the orbit of the satellite, approximately equal to the Earth's surface. The reason why the satellite could not fall was because of the high-speed centrifugal movement. ）

Now the prototype is a two-cockpit design, and the cockpit canopy of the aircraft, because of the lack of temporary material technology, must not be assisted by traditional means such as spells, and the cost is expensive.

At this time, Hua Baixiang had already changed into a combat uniform special for fighters - simple and neat. However, the simple combat uniform can't hide the plump figure of Hua Baixiang.

Hua Baixiang sat in the back, and Zhang Hao sat in the front. The canopy of the fighter was slowly closed under the control of a DC motor.

"What's driving this hatch? How is there a buzzing sound? It's not a formation. "Flower Passion is curious.

Zhang Hao shrugged, "A technology of the Ocean Group. ”

Motor technology, Dayang Group has never been sold to the outside world. Because the motor technology involves the electromagnetic principle, and this is the technology that the current Dayang Group will never leak.

Electromagnetic technology, involving generators, etc., is also related to high-voltage electricity, which is an important technology for artificial fairy gas, which is the most important secret of Dayang Group.

In addition, in the current technical system of Dayang Group, the electric motor has an irreplaceable role. However, among the commodities sold by Dayang Group, such as automobiles and machine tools, the electric part has been replaced by formations.

Replacing with a formation method has high cost, poor controllability and low accuracy...... Only the profits are high.

Hua Baixiang didn't get an answer, but immediately used her spiritual sense to scan the driving position of the hatch, and naturally found an electric motor and a complex deceleration device. It's a pity that although spiritual sense is good, it is not omnipotent.

Spiritual consciousness is more like a kind of 'tentacle', a kind of tentacle of mental structure, which can be easily identified for what is known, and a little more laborious for the structure that is not known.

Hua Baixiang snorted lightly, "It seems that the Dayang Group has a lot of hidden technologies. ”

"Sit down, fasten your seatbelts, the plane is about to take off. Zhang Hao began to operate. During the research process of the aircraft, Zhang Hao participated in many visits, and even gave a lot of suggestions, so he knew how to control the aircraft.

Through the intercom radio device, Zhang Hao made contact with the ground and determined the liftoff.

Zhang Hao lit the fire, slowly pushed the accelerator, the plane trembled suddenly, and then made a faint hissing sound, the sound slowly increased, after about a minute of warm-up, Zhang Hao said again: "Sit down!"

Before she could finish speaking, the roar of the plane suddenly increased, and began to accelerate, at first the acceleration was not large, but after a few seconds, there was a powerful explosion of acceleration, and Hua Baixiang was looking at the console in front of her, and the rapidly increasing force pulled her back to her chair.

The speed of the aircraft increased rapidly. Hua Baixiang is a master after all, and quickly adapted to the pressure, and once again looked at the operating table, as well as the surroundings.

Through the hatch, you can see that everything around you is rapidly receding. Suddenly, everything around me began to fall...... It's the plane that has taken off.

In a roar, the plane soared into the sky like lightning.

Zhang Hao couldn't talk to Hua Baixiang, and was communicating with the ground. Soon Zhang Hao determined the voyage:

The plane climbed to an altitude of 500 kilometers, sailed at supersonic speed, and reached the "Chengshanjiao" southwest of the "Tianshui Country" to complete the attack.

Tianshui Country is one of the three countries assigned by Tiandu to the Ocean Group, and it is the farthest away from the Ocean Group.

Chengshanjiao is the westernmost part of the entire Continent of Soil, which is equivalent to the location of Changshan Port of the Ocean Group in the Continent of Fertile Soil.

It's just that Chengshanjiao has not been developed because it is too desolate - just like Changshan Town ten years ago. It's even more desolate, with only a few villages, now relocated.

With no population and no economic base, the Ocean Group decided to develop it only recently.

The Neptune Group has developed development plans for the three southern countries. Of course, it cannot be called the three southern countries now, and now it has been planned by the Dayang Group into 10 large administrative regions.

And this time to test a new ballistic missile, we are going to clean up the corners of the mountain here and destroy the primeval forests here.

The plane roared up to an altitude of 500 kilometers without stopping all the way, only after breaking out of the aura layer, the climbing angle was adjusted.

The heavy pressure, combined with the acceleration of the plane, made it a little difficult for Hua Baixiang. But what really made Hua Baixiang's face solemn was the target of the Ocean Group's attack this time: Chengshanjiao!

The straight-line distance from Dayang Group to Chengshanjiao is about 13,500 kilometers. There is a vast sea in between, and it is impossible to discern the direction with the naked eye.

Dayang Group chose Chengshanjiao as the target of attack, and it is by no means simple!

When she set off this time, Hua Baixiang was still a little puzzled - Zhang Hao was too easy to talk this time!

Hua Baixiang is very self-aware and knows his own catties. Zhang Hao so readily agreed to visit the aviation research center of Dayang Group this time, and even promised to try a new aircraft, Hua Baixiang was a little puzzled in her heart.

This is the core technology and research base of Dayang Group, when is it so easy?

As for Zhang Hao being fascinated by himself, Hua Baixiang definitely didn't have this idea.

It was only at this time, after hearing that the target of the attack this time was Chengshanjiao, that Hua Baixiang suddenly woke up - she was 'demonstrated'!

The Ocean Group can attack the corners of the mountain, and it can attack the mountain gate and Tiandu Mountain of the Tiandu faction!

Turning his head to look at the outside world, it was hazy below, with white clouds under his head and feet, and he couldn't see the ground!

This situation made Hua Baixiang a little panicked - she had also piloted a propeller plane before, but after the plane flew over the aura layer, Hua Baixiang was horrified to find that she was lost!

I can't see the ground, and naturally there is no ground as a reference, and the flowers can't even tell the difference between up and down, left and right.

When flying during the transformation period, they all fly close to the ground, at least you can see the ground under your feet.

Nowadays, most of the pilots of the planes in the Holy Land also fly on sunny days, and they can see the ground as a reference.

But now, the ground is not visible at all, and the plane flies directly to an altitude of 500 kilometers, and it is difficult to see the ground even on a sunny day - it is hazy.

But at this time, the plane was flying all the way forward under the guidance of the radio.

At this time, the aircraft has reached 1.2 times the speed of sound and continues to accelerate.

Hua Baixiang heard the call between Zhang Hao and the ground, suddenly remembered, and hurriedly asked in a soft voice: "Mr. Zhang, we broke through the speed of sound, Dad, we didn't seem to hear the sonic boom sound on the ground just now?"

Zhang Hao said without replying: "You said it, we exceeded the speed of sound, and the sound behind us couldn't catch up, so naturally we couldn't hear it!"

"More than the speed of sound......" Hua Baixiang was stunned for a moment, and then gradually reacted. Is this hypersonic?

Although the flight of the previous transformation period could also exceed the speed of sound, because of the use of the formation, there was no sonic boom, and everyone didn't care. At this time, there is a sonic boom phenomenon, and then thinking about the word 'supersonic', Hua Baixiang has a new understanding.

But soon, Hua Baixiang put her mind on the flight at the moment.

The planes of the Ocean Group, without ground reference and under the guidance of radio, actually crossed the sea like this.

Hua Baixiang's face became more and more dignified, such excellent aircraft technology really made Hua Baixiang feel the threat and the pressure of the future development of Tiandu School!

Previously, Hua Baixiang had always felt that the Dayang Group was having a head cramp to develop aircraft technology, and it was not until the war in the East a few days ago that Hua Baixiang felt the excellence of the aircraft for the first time. But the planes of the moment, this brand new supersonic aircraft, seem even more terrifying.

At a flight altitude of 500 kilometers, there is no aura and you can't see the ground, even if you are a god master at this altitude, you have an inexplicable panic - leaving your familiar environment.

It is only at this height that you can feel the insignificance of the individual!

Even if it is already in the god transformation stage, in this vast world, it is still just an ant.

The plane accelerated in less than two minutes and its speed had already jumped to 3.2 times its ultimate speed. At this speed, the drag of the air is comparable to the thrust of the aircraft, reaching an equilibrium.

The plane flew by at a rapid pace, leaving a faint trail behind it. It's the exhaust fumes of combustion, and there are also traces left by the supersonic speed of an airplane – water droplets or ice crystals that are precipitated by the compression of the air.

It took less than two and a half hours for the plane to reach its target. Under the guidance of the radio, there turned out not to be much deviation. From afar, I could see the colorful flashes of the sky in the distance. That's the light coming from the ground, for guidance.

"Ready to dive!" Zhang Hao took a deep breath, and the plane began to fall.

Under the influence of gravity, the speed of the aircraft began to climb. Moments later, the plane was 3.5 times the speed of sound!

"Coming to the aura layer!"

The plane shuddered suddenly. After entering the aura layer, the plane drifted a little as gravity began to decrease, but this was all expected. At the moment when the plane entered the aura layer, the wind removal array on the surface of the plane was also activated, and the impact was quickly eliminated.

The wind-repellent formation reduces the drag of the aircraft, but does not reduce the lift of the aircraft, and the arrangement of the formation is rigorously calculated.

In fact, if someone on the ground could hear it, the moment the plane crashed into the aura layer just now, there was an explosion in the entire sky. But the plane was too fast for the sound of the explosion to catch up.

The plane penetrated the clouds and quickly lowered to an altitude of 20 km.

"Start pulling up!" Zhang Hao shouted, also speaking to the ground. The plane began to raise its head, and a huge acceleration acted on the inside of the aircraft. Because of the sturdy structure of the plane and the fact that all cultivators don't need to consider the load of the human body, the overload acceleration at this moment is as high as more than 20 times the gravity!

The instantaneous overload made the flower potion change slightly.

The plane streaked a huge arc in the sky and changed to horizontal flight at a high speed of less than 5 kilometers above the ground.

At this time, under the cover of the formation, the speed of the aircraft has exceeded five times the speed of sound.

Hua Baixiang clutched her chest, looking at everything that was rushing by on the ground, a little stunned. Because of the speed, the scenery that passes by the ground has begun to abstract away, and it seems that only a jumble of lines and blocks of color remains—because the speed is so fast, the eye can no longer process too much information.

"Prepare to attack!" Zhang Hao confirmed with the ground again. At this time, the plane was still about twenty kilometers away from the target direction.

Zhang Hao began to activate the sight - this is a solidified instrument, the aircraft speed, air resistance/density/altitude, wind speed, attack angle, etc., are all pre-processed, and when attacking, as long as the pointer of each data is dialed to the position, the result is automatically output.

It's a mechanical 'half-computer', and the results aren't very precise, but they're good enough. Anyway, it doesn't matter if the deviation is one or two hundred meters.

Hua Baixiang looked at it curiously, without blinking. It is not known how this new aircraft, which should be attacked. and what Zhang Hao said before'metal hydrogen and oxygen bomb', which also made Hua Baixiang very curious.

Zhang Hao quickly took aim, and under Hua Baixiang's attention, he suddenly pressed the launch button on the control stick.

Hua Baixiang only felt that the left side of the body seemed to be lighter and slightly upturned, but quickly regained her balance. Almost at the same time, a blue flame was seen flying out from under the plane, flying forward.

Immediately after completing the launch, the aircraft turned, climbed, and flanked the attacking target. When Hanami looks sideways, you can see the 'flames' flying away in the sky and the white trails left behind.

"Is this a ballistic missile?, can you fly out on your own?" asked Hua Baixiang.

Zhang Hao did not open his mouth and continued to communicate with the ground.

The ballistic missile flew out at the initial velocity of the aircraft, which quickly climbed to six times the speed of sound, and in less than six seconds, the missile flew to the designated target - when the missile was launched, the plane was only 17 kilometers away from the target.

Hua Baixiang can see that there seems to be a deviation between the missile and the target, and it is roughly estimated that there is a look of three or two hundred meters.

But the next moment, Hua Baixiang saw a scene that she could never forget for a lifetime.

The ballistic missile exploded! But the way it exploded was completely different from the shells of the past!

It exploded in mid-air before it hit the ground.

First, the first explosion caused the ground to collapse, but more importantly, a large amount of fog gushed out from the missile, and with the assistance of the first explosion, it spread along the ground and in all directions, covering a radius of about a kilometer in the blink of an eye.

Then there was a second explosion. The first explosion was almost negligible compared to the second.

The second explosion seemed to blow the entire sky apart.

But seeing a pale blue flame instantly swept over a kilometer radius, ripples suddenly appeared in the sky, spreading to all sides. Swept away by the ripples, the grass and trees were directly shattered, the rocks were shattered, and the earth and mountains were lifted up a layer of earth and rolled away in all directions.

That's a shockwave, right?!!! Although the distance is a bit far, I can't feel the power of the explosion firsthand. But it looks crazy.

I just don't know how the power of such an explosion compares to the power of the cannonballs in the past and the attack power of the Transformation Period?

The plane did not leave, but flew 50 kilometers away, hovering at high altitude. By this time the speed of the aircraft had been reduced to subsonic speed.

The sound of a crazy explosion seemed to tear the heavens and the earth apart, rolling in.

Zhang Hao also needed to look at the scene of the explosion and estimate the scope of the explosion. There are also staff on the ground who are busy, testing the power of the explosion and collecting data.

Only the flower herb is purely to watch lively. But as the second explosion ended, a large amount of water vapor suddenly appeared in the area of the explosion, and this water vapor tumbled into the air, gradually forming a large, white mushroom cloud.

The mushroom cloud was tumbling, about a kilometer in diameter, and the altitude continued to break through, rising to an altitude of more than thirty kilometers after an hour. Only then did it stop rising and basically stabilized.

This mushroom cloud is very white and looks very beautiful. However, thinking about the journey of this mushroom cloud, Hua Baixiang trembled a little.

Because of the distance, she didn't feel the power of the explosion directly. But compared to the range of the mushroom cloud traveled by the previous shell explosion, Hua Baixiang can roughly estimate the power of this explosion at the moment—almost a thousand times the power of the explosion of the second-generation Thunder Cannon!

Getting this result, Hua Baixiang couldn't help but tremble, "Zhang Hao, what kind of shell is this?"

"It's a missile! A ballistic missile! The core technology of its explosion is metallic hydrogen. A substance newly researched by the Ocean Group. It is also the first bomb made by the Ocean Group to completely get rid of the aura.

Next, we are going to compress the aura into metallic hydrogen, which is expected to double the power of the explosion. ”

Flower Potentia: ......

Lunatic!

At this moment, Hua Baixiang had only one thought in her heart: the people of Dayang Group are all crazy!
