Black technology, starting from daily check-in

Looking at the Xuannv space fighter that looks like a black sword hilt on the platform, Lin Yu couldn't help but admire and said: "Yes, this painting design is very good, and it perfectly integrates the future sci-fi style."

Hearing Lin Yu's praise, everyone present smiled.

"Mr. Lin, this is a painting designed by Fuxi. There are currently two sets in total, and the other one is red and blue."

Zhao Yu waved his hand and asked the artificial intelligence to release the holographic projection of the second set of paint design.

next second.

A red and blue 3D holographic projection virtual fighter appeared in the air.

It's different from the first set.

This second set of Xuannv aerospace fighter does not have a cockpit, not even a seat, it is truly unmanned.

After a brief glance, Lin Yu asked, "Have all the systems of Xuannv been tested?"

"Yes, it's just short of the first flight."

Zhao Yu nodded.

"Then what are you waiting for, let's start directly."

Lin Yu ordered.

Hearing this, Zhao Yu beckoned to the distance.

Soon, a middle-aged man in a black special combat uniform came over and saluted everyone with a swipe.

Then, he looked at Lin Yu and said with a solemn expression: "Mr. Lin, hello, I am the first flight officer, Xu Zhen, and it is a great honor to be able to fly the Xuannv Aerospace Fighter."

"Hello, Comrade Xu Zhen, please get on the plane."

Lin Yu smiled and said.

Xu Zhen saluted, then turned and walked towards Xuannv Sky Fighter.

Engineers moved quickly to carry out testing work.

10 minute later.

"The force field drive system is normal!"

"The variable cycle engine is normal!"

"everything's ready!"

The sound of reports kept ringing one after another.

Lin Yu looked at Zhao Yu, nodded slightly, indicating that it was time to start.

Zhao Yu didn't hesitate, and raised his voice: "Open the skylight and get ready to take off!"

The voice fell.

The originally motionless Xuannv Aerospace Fighter suddenly had a faint white light on its tail.

White light gathered at the jet port at a terrifying speed, and countless light particles were spinning at extreme speed, like two deep white holes.

Gorgeous and magnificent.

At this time, relevant feedback data also appeared on the control panel.

"The power system is good, the energy output is stable, and the variable cycle engine and force field drive system can be started."

"Engine and force field drive activated."

"three!"

"two!"

"one!"

"Startup complete!"

With the end of the countdown, a small voice suddenly sounded.

Buzz! !

next moment.

The white light seemed to have reached a certain critical point, bursting out into a blazing light.

Immediately afterwards, a powerful energy rushed over.

The space around the Xuannv Aerospace Fighter seemed to be distorted, and it began to become a little blurry.

Obviously, this is caused by the forcible change of the surrounding magnetic field by energy.

This sudden electromagnetic change spread almost instantly, sweeping the scene.

For a moment, the hairs of all the people present stood on end, enjoying the feeling of static electricity all over their bodies.

"What a big formation."

Zhao Yu said with some horror.

The force field driving device was fully activated, and the Xuannv space fighter slowly suspended in the air, standing still.

"The system is fine."

The chief engineer quickly issued a report.

Seeing this, Lin Yu picked up the communication headset and asked, "Xu Zhen, how do you feel?"

"It's not bad, but there is an illusion that the body is very light, and I feel a little uncomfortable."

Xu Zhen's voice came out from the communication channel.

"It's okay, this is a normal reaction after the force field drive system is activated, because the gravitational force between you and the Xuannv Fighter has been canceled out, so you will feel very light."

Lin Yu explained with a smile, then looked up at the window showing the blue sky above, and said, "Okay, you can prepare yourself for overload. Now that the skylight has been opened, you are ready to go."

"Yes!"

Xu Zhen took a deep breath and began to increase the power of the force field drive system.

Soon, the Xuannv space fighter slowly floated into the sky, and left the secret base along the window.

Now the power of the Xuannv fighter is not fully turned on, only the force field driving device is maintained.

Because if the variable-cycle engine is started inside the secret base, the astonishing acceleration brought about in an instant will compress the surrounding air to an incredible level.

This is equivalent to having a fighter jet break the sound barrier at such a close distance.

The consequence is that, except for Lin Yu, all the people on the scene will die on the spot in all likelihood.

Therefore, Xu Zhen controlled the Xuannv Aerospace Fighter, came outside the secret base, and kept rising, standing above a thousand meters above the sky.

At this time, the surrounding airspace has long been emptied of martial law.

Under the blue sky and white clouds, only the Xuannv space fighter hovered in the air, motionless.

Control room.

Lin Yu and others can use the signal sensor on Xuannv's fuselage to carry out detailed positioning, so that it can come back from outer space.

Otherwise, without coordinates, Xu Zhen would easily get lost in the universe.

Of course, the Xuannv fighter is equipped with an environmental control system.

It includes multiple modules such as air supply control, cabin pressure control, temperature control, and humidity control.

Not only can the temperature be adjusted independently, but also a series of indicators such as air supply, pressure, and humidity in the cockpit can be adjusted to keep the driver's environment stable at all times.

Therefore, even if Xu Zhen stayed in outer space for a period of time, there would be no big problem, at most he would starve to death.

"Mr. Lin, I'm going to start."

Xu Zhen said slowly.

Hearing this, Lin Yu hurried out of the main control room and rushed to the outside of the secret factory.

Behind him, Zhao Yu and others hurriedly followed.

Soon, Lin Yu and others came outside the spacious venue.

Here, you only need to look up to see the Xuannv space fighter floating in the sky.

The line of sight is very clear.

"Mr. Lin, here it is."

Next to him, Zhao Yu handed over a pair of earplugs.

Lin Yu took it and put it on, and then explained to the people behind him: "Everyone put it on, there will be a lot of movement later."

Everyone was stunned, and quickly took it from Zhao Yu's hand and put it on.

It didn't take long for everyone to wear it.

In the sky.

Xu Zhen started the force field driving device and the variable cycle engine with all his strength.

And at the moment of activation, the tail of the Xuannv Aerospace Fighter suddenly burst into a fiery blue torrent!

Countless brilliant light particles violently rioted in the sky.

The surrounding space was directly distorted by the terrifying force, forming a huge white vortex.

boom!

Accompanied by a thunderous explosion, a huge sound barrier cloud suddenly appeared.

And, not just a sound barrier cloud.

Instead, a series of sound barrier clouds are combined together, as if forming a sound barrier cloud channel, straight into the sky!

In the eyes of Lin Yu and others, Xuannv's space fighter disappeared into the sky almost instantly.

Then, the sky seemed to be torn apart, leaving a clearly visible trace of the sound barrier cloud, and this trace spread all the way to the end of the field of vision, like a ladder!

At the same time, after a full two or three seconds, a huge sonic boom resounded through the sky.

The rumbling sound was like bombs exploding in the ear, very shocking.

For a moment, everyone turned pale.

"Good guy, this movement is too big!"

Zhao Yu said with a pale face.

The researcher next to him also nodded in agreement.

"This speed is really terrifying. It even starts at the speed of sound. If it is on the battlefield, if the surrounding soldiers get closer, they will be shocked to death by the sonic boom."

"Yeah, no matter how fast the j20 is, it's just too far behind the Xuannv Aerospace Fighter. Just now, I felt my eyes blur and my ears explode, and Xuannv disappeared."

"I don't know where Xuannv is now, maybe she has already left the earth?"

"It shouldn't be such an exaggeration. According to Xuannv's design data, its forward speed in the atmosphere is 1700 meters per second, and it should still be inside the earth now."

There was a lot of discussion.

Lin Yu took off his earplugs and said with a smile, "Xuannv's maximum speed in the atmosphere is only [-] kilometers per hour, which is barely okay."

"When Xuannv arrives in space, its speed will reach 11.2 kilometers per second, which is the real extreme speed."

"11.2 kilometers per second?"

Hearing this outrageous data, Zhao Yu couldn't help but be speechless secretly.

Lin Yu smiled and walked towards the main control room.

Physicists divide the Earth's atmosphere into five layers.

They are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

The outer edge of the stratosphere, the uppermost limit for aircraft to fly on air support.

Therefore, the distance from the earth to space is only 300 kilometers in total.

Above 300 kilometers is the orbit of satellites, and if it goes further up, it is the orbit of planets.

And according to Xuannv's maximum speed in the atmosphere, it takes at most 2 minutes to reach space directly.

If it is extremely fast in space, it will be even faster. It only takes 30 seconds to fly directly to the outer atmosphere.

Soon, Lin Yu and others returned to the main control room.

"Xu Zhen, how are you doing now? Is there anything wrong?"

Lin Yu contacted Xu Zhen in the communication channel.

However, after Lin Yu finished speaking, there was no response in the communicator.

"Mr. Lin, what's going on, it must be something wrong with Xuannv."

Seeing this scene, Zhao Yu asked nervously.

And everyone at the scene also became worried.

You know, this is the first test flight of the Xuannv Aerospace Fighter.

Prior to this, there was no precedent in the world that could prove that fighter jets could fly into space.

In addition, the environment in space is very harsh, if there is any system failure in Xuannv, then things will become a big mess.

The more you think about it, the more dignified the expressions on everyone's faces.

In the gradually serious atmosphere, Lin Yu said calmly: "Before the test flight, we have already tested Xuannv, and the engineers have not found any problems, so don't scare yourself."

"As for why there is no communication from Xu Zhen, I think it is probably because of the delay of communication."

"Communication delay?"

Everyone was taken aback, a little confused.

"That's right, because we captured all the communication satellites, Xuannv's artificial intelligence system will automatically switch, and switching communication and sending messages will be delayed due to distance."

Lin Yu explained a sentence unhurriedly.

"Mr. Lin, what do you mean to say that Xuannv has arrived in outer space now, and there is still a communication delay?"

Zhao Yu quickly realized, with an incredulous expression on his face.

Good guy.

How long has it been.

I'm afraid it's less than 5 minutes.

Xuannv has already gone to a place where communication is delayed?

This is too sci-fi!

Just when Zhao Yu was feeling emotional.

In the communicator, Xuannv's signal suddenly appeared.

Xu Zhen's voice finally came back from the distant outer space.

However, because the distance is too far, his voice is very noisy.

"Mr. Lin, everything is normal here."

Hearing this answer, everyone at the scene let out a long sigh of relief, with a smile on their faces.

Lin Yu asked, "where are you now?"

About ten seconds later, Xu Zhen's voice came back, saying: "Mr. Lin, I have now completely escaped the earth's outer atmosphere and come to space in the true sense."

"The current position I am in is exactly in the middle of the earth and the moon."

"According to the route planning of artificial intelligence, I only need about 40 minutes to reach the surface of the moon directly."

As soon as these words came out, everyone present was a little shocked.

"It only takes more than 40 minutes from the earth to the moon?!"

"How is this possible! It seems that only six or seven minutes have passed since we took off just now!"

"Even if you add these few minutes, it will only take about five or ten minutes. It takes less than an hour to reach the moon? This is too fast! How far is the moon from us?"

"I remember it was more than 38 kilometers."

"Didn't Mr. Lin just say that Xuannv's top speed is 11.2 kilometers per second, if converted into Mach, that's Mach 33, which is 40427.64 kilometers per hour!"

"Oh my god, this is too exaggerated. It will take more than an hour for us to take the high-speed train casually!"

Everyone exclaimed, their faces full of disbelief.

at the same time.

In the desolate endless starry sky, the Xuannv Sky Fighter turned into a ray of white light and was flying at extreme speed.

Due to the high flying speed, the Xuannv fighter jet was surrounded by many high-energy particles.

These high-energy particles that reached the escape velocity formed a light phenomenon surrounded by particles on the fuselage of the Xuannv fighter.

From a distance, it looks like a glowing white sword hilt flying in space, it looks shining and cool.

However, cool is cool, but the driver Xu Zhen is not feeling well right now.

Although Xuannv has a super buffer system, this incredible speed still puts a lot of pressure on Xu Zhen.

It can be said that he has probably endured an overload of six to seven gs as a whole.

Under normal circumstances, the limit that a healthy ordinary adult male can bear will not exceed 6 to 6.5 g.

And strong athletes generally will be unconscious at 7.5g.

Only aerobatic pilots or astronauts who have undergone long-term training can reach the limit g value of 9g.

But will not exceed 12.0g.

Because 12g is already the limit of human beings.

In the case of 12g, even a stunt pilot will be unconscious within 1.5 seconds.

As for Xu Zhen, he is an ace pilot, and he can easily withstand an overload of six to seven g.
