It's reasonable for me to have a two-way foil for a second-level civilization, right?

Cao Liangcai stopped talking nonsense with Lu Yongchang, and directly issued orders to Bai Yixuan.

"No! Can't return!" Lu Yongchang's expression suddenly turned serious.

"Master, is it alright for me to call you "Master?" Cao Liangcai didn't know whether to laugh or cry, "Well, what are you doing in the sky?"

Lu Yongchang was silent for a moment, then whispered.

"I said that I want to lead Xia Guo to the universe."

"It can't be the end. I, the administrator of the space agency, have never been in space, have I? This is a bit unreasonable, right?"

"What's more, seeing the universe with my own eyes will help me in my next research."

"Academician Cao, I do scientific research for the starry sky above my head. Do you understand?"

Hearing Lu Yongchang's words, Cao Liangcai fell silent.

As a scientific researcher, Cao Liangcai naturally understands the feeling that he will die soon after he hears about it.

After a long time, he sighed slightly.

"Hey... okay, let you go."

"However, I need to report this matter to Minister Hong and the chairman of the assembly."

Lu Yongchang's complexion suddenly collapsed: "This... I'm afraid it's not very good?"

"The two of them are so busy, don't you need to bother them with such a small matter?"

"No way!" Cao Liangcai snorted coldly, and said angrily, "Okay, I won't talk to you anymore."

"Where's Bai Yixuan?"

"Academician Cao, I'm here." Bai Yixuan in the driver's seat responded quickly.

"Remember, Professor Lu is Xia Guo's future!"

"No matter what method you use, you have to send Professor Lu back to me safely! Did you hear me!"

"Otherwise, you are the eternal sinners of Xia Kingdom!"

Cao Liangcai spoke in a heavy tone.

"Yes!" Bai Yixuan's face turned serious, and he replied loudly, "Please rest assured, Chief!"

Chapter 75 Geosynchronous Orbit

After the radio communication ended, the atmosphere in the cabin suddenly became tense.

"Cough cough!"

Lu Yongchang twisted his body uncomfortably: "Everyone, don't be so dull, we have to fly for a long time!"

Bai Yixuan in the driver's seat changed his expression slightly, and said in a deep voice, "Professor Lu, please follow our instructions from now on!"

"Hong Fan, check the seat belt again for Professor Lu!"

"Yes!" Hong Fan stretched out his hand to unfasten the seat belt on his seat, got up and checked for Lu Yongchang.

"I said... there's no need to be so serious, right?" Lu Yongchang looked helplessly at Hong Fan in front of him, "I won't make fun of my own life. I have simulated it many times, and I promise nothing will happen!"

"Professor Lu, I am a soldier, obeying orders is my bounden duty!"

Bai Yixuan's faint voice came from the front: "Since Academician Cao has given us an order, next, we will protect your personal safety at all costs!"

"If..." At this point, Bai Yixuan's voice paused slightly, "If something really happens, use my escape device to escape!"

There were originally three sets of escape devices stored on Xuannv No. [-].

Each set of escape equipment includes a high-altitude skydiving device, protective clothing and oxygen cylinders.

Although these devices cannot guarantee the safety of drivers in space outside the atmosphere, they can still bring people back to the ground safely in the atmosphere.

After Bai Yixuan's voice fell, the atmosphere inside the cabin of Xuannv No. [-] became heavy again.

Lu Yongchang was slightly moved.

Subconsciously, he touched his nose with his hand and said softly, "Actually... I secretly brought up an escape device, which is right behind the cabin."

The three of Bai Yixuan: "..."

"Ahem! Professor Lu, we have reached the predetermined altitude. Next, the flight attitude of Xuannv-[-] will undergo some changes. If you feel uncomfortable, please let us know!"

Bai Yixuan changed the topic with a straight face.

awkward!

So embarrassing!

He was even ready to sacrifice!

In the end, the man actually brought an escape device himself!

what is this? !

Thoughtful?

Of course, if Lu Yongchang knew Bai Yixuan's mental activities at this time, he would tell him sternly.

Sorry, it's just a simple fear of death.

He didn't want to live another life, but he was planted in this kind of place for no reason!

……

As Bai Yixuan flipped a few buttons on the console in front of him, a cool white light slowly lit up inside the cabin.

"drop!"

As a reminder sounded for the system self-check, Bai Yixuan's expression suddenly became serious.

"The air pressure is stable!"

"The oxygen content is normal, the oxygen generator is operating normally, and the air filter is normal!"

"Hall thruster power is normal!"

"Get ready to speed up!"

As the sound of orderly and compact reports came to Lu Yongchang's ears, the flight posture of Xuannv No. [-] changed a little.

As the nose of the plane gradually rises, Xuannv No. 60 presents a [-]-degree inclination to the ground.

The next moment, a stronger vibration came from under his feet!

The rate at which deuterium-tritium bubbles appeared in the small fusion reactor increased rapidly, and bursts of astonishing energy were quickly released from the interior of the deuterium-tritium atoms!

Immediately afterwards, the faint blue flame at the tail of Xuannv No. [-] became stronger again!

The huge recoil force pressed Lu Yongchang firmly on the seat again!

"Professor Lu, how is it? Can this acceleration be tolerated?"

Bai Yixuan's questioning voice came from the side.

Listening to his voice, it seems that such acceleration is very easy for him.

On the other hand, Lu Yongchang blushed slightly, nodded with some difficulty and said, "Don't worry, I can bear this kind of acceleration!"

Xia Wanyi on the right turned her head to look at Lu Yongchang with some anxiety, and said softly: "How about... let's slow down a bit?"

……

In areas with dense atmosphere, the limit flight speed of Xuannv-5 is around Mach [-].

But in the high-level space where the atmosphere is thin, with sufficient acceleration time, the highest speed of Xuannv-7.9 can reach the first cosmic speed, 23.2km/s, which is about Mach [-].

After entering the geosynchronous orbit, without the influence of the atmosphere, after a long period of acceleration, the flight speed of Xuannv-11.2 can even reach the astonishing second cosmic speed, [-]km/s!

This is also the minimum speed required for Xuannv-[-] to go to the moon!

But even so, because of Lu Yongchang's physical condition, it took Xuannv-36000 a full five hours to reach the [-]-kilometer geosynchronous orbit.

Although it seems to take a long time, compared with the previous satellite orbiting time, Xuannv-[-] can be called super fast!

Low-orbit satellites, that is, low-earth orbits hundreds of kilometers from the surface of the earth, generally only need a few ten minutes to complete from launch to orbit.

If it is a geosynchronous orbit of 36000 kilometers, a satellite often needs to go through a long journey of nearly a month before it can successfully enter orbit!

After all, the rocket will only push the satellite into a low-Earth orbit hundreds of kilometers from the surface, and the rest of the journey must be done by the satellite itself.

……

As the height of Xuannv No. [-] gradually climbed, the scenery outside the porthole gradually changed.

The distant horizon gradually turned into a circular arc glowing with crystal light.

Next, what caught Lu Yongchang's eyes was a pitch-black cosmic space, like a pure black curtain!

And on this pure black curtain, dotted with sparkling gems that glow faintly.

Those crystal gems with faint light are stars tens or even hundreds of thousands of light-years away from the earth.

At the same time, a sense of weightlessness struck.

Lu Yongchang, who experienced this feeling for the first time, frowned slightly.

To be honest, not very good.

"Professor, we're here!"

Bai Yixuan's voice reached Lu Yongchang's ears.

Thanks to the good airtightness of the Xuannv-[-] cabin and various oxygen generators and air filtration devices, as long as they leave the cabin, everyone does not need to wear bulky spacesuits all the time.

"so beautiful……"

Lu Yongchang stared intently at the distant starry sky through the porthole in front of him with deep eyes.

His heart moved slightly.

That's the direction of Proxima Centauri.

As a red dwarf star only 4.22 light-years away from the earth, its visible magnitude is 11. Therefore, Lu Yongchang cannot observe it with the naked eye.

But even so, Lu Yongchang still had some inexplicable agitation in his heart!

Perhaps the future of mankind lies near that distant red dwarf star!

"Call the ground control center, call the ground control center, Xuannv-[-] has reached the synchronous orbit, please instruct!"

Bai Yixuan's voice interrupted Lu Yongchang's meditation.

"Chi... Chi... Received, Xuannv No. [-], report your situation!"

Chapter 76 Why don't I go up next time?

Beijing.

Office of the Speaker of Parliament.

The moment Xuannv No. [-] pierced the sky, Mr. Li showed a somewhat gratified smile on his face.

It worked!

"Jingle Bell……"

A piercing bell sounded from the side.

Councilor Li frowned subconsciously.

For the test flight of Xuannv No. [-], he had already postponed everything, so why would there be a phone call?

While thinking, Mr. Li reached out to pick up the handset of the landline on the desk.

"Chairman, I am Cao Liangcai!"

Hearing the voice in the microphone, Councilor Li's expression instantly eased a bit, and he said with a smile: "Academician Cao, I have already seen the scene of Xuannv-[-] taking off!"

"...Chairman, this is not what I want to talk about." Cao Liangcai swallowed slightly, "Chairman, you have to be mentally prepared."

Councilor Li frowned, and his expression became a bit serious: "What? Something went wrong with Xuannv No. [-]?"

"Xuannv No. [-] is fine..."

Cao Liangcai muttered in a low voice, "Professor Lv Yongchang is the one who has the problem."

Mr. Li: "???"
