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

Lu Yongchang's eyes moved slightly.

It's about to take off!

Excitement flashed in his eyes.

"Xuannv No. [-] received it!"

"The output power of the small fusion reactor is normal!"

"Ready to activate the Hall thruster!"

"..."

An announcement came from the headset in the helmet.

Lu Yongchang couldn't help becoming a little nervous.

Even though he is a human being in two lifetimes, this is his first time on an aerospace plane and his first time in space!

"Three, two, one, take off!"

Following Cao Liangcai's order, Bai Yixuan in the driver's seat firmly pushed the joystick on the console.

A slight tremor came from the soles of his feet.

Hall thrusters activated.

As soon as this thought flashed through Lu Yongchang's mind, he felt himself being pressed against the back of the chair by a huge force!

……

In the fighting shark live broadcast room.

"Why hasn't it taken off yet..."

"The flowers I've been waiting for are all thanks~"

At the moment when all the netizens were waiting anxiously, a calm voice of command came.

"30 seconds to takeoff!"

Hearing the voice of command, the netizens in front of the computer were suddenly refreshed.

In the live broadcast screen, a faint blue flame slowly appeared at the tail of the Xuannv-[-] aerospace plane.

"Fuck! Fuck! What is that?"

"One, two, three, four, five... there are so many Mach rings!"

"Is this the tail flame of the Hall thruster? Love love love love!"

"Come on, put me on the shelf and roast me to cheer up the big guys!"

The 30-second waiting time passed quickly, and as the order to take off was issued, the faint blue flame at the tail of Xuannv No. [-] suddenly increased several times!

The next moment, under the impetus of the Hall thruster, Xuannv No. [-] began to accelerate slowly.

In the blink of an eye, it came to the end of the runway!

As the nose of the aircraft tilted upward, Xuannv No. [-] jumped into the blue sky!

The moment this scene was recorded by the camera, there was naturally another howl of ghosts and wolves in the live broadcast room!

"It's taking off! It's taking off!"

"Fuck, this tail flame, this appearance... Let alone, the ten-year-old fan of Xuannv No. [-] came here uninvited!"

"It is said that Xuannv No. [-] is an aerospace plane, so where is the destination of this test flight? It won't be just a circle in the sky, will it?"

The host of the live broadcast seemed to have seen this barrage, and explained softly: "The destination of Xuannv-3.6 this time is a geosynchronous orbit [-] kilometers above the surface."

"Hiss... it turned out to be a synchronous orbit!" Zhao Zijie, who was sitting in front of the computer, gasped suddenly.

Take off from the surface and go directly to the synchronous orbit... The power of Xuannv No. [-] is probably more exaggerated than anyone imagined!

Not to mention how many satellites of other countries are in the synchronous orbit, nor whether Xuannv-[-] carries weapons or equipment, even if it just throws a tungsten rod down, most countries cannot bear the consequences!

Under the shooting of the high-speed camera, the figure of Xuannv No. [-] clearly appeared in the live broadcast.

After taking off, the faint blue flame at the tail of Xuannv No. [-] intensified again.

Unlike ordinary chemical fuel engines, the wake of the Hall thruster is a high-speed plasma at hundreds of millions of degrees Celsius.

Therefore, in the atmosphere, the tail flame of Xuannv-[-] is particularly spectacular!

Countless Mach rings are densely distributed in the ten-meter-long blue flame!

Before waiting for all the netizens to send out a barrage of emotion, the nose of Xuannv No. [-] suddenly pulled upwards.

Driven by the Hall propeller, the whole plane climbs up with a slope close to 90 degrees!

"Oh!"

A loud noise came from the sky!

A beautiful sonic boom cloud instantly appeared around the fuselage!

At the moment when the sonic boom cloud appeared, the number of barrage in the live broadcast room instantly increased dozens of times!

"Fuck, fuck, fuck!"

"Mom, come out and see God!"

"Is this the speed of sound? Good guy, the mobility of Xuannv No. [-] is too strong, right?"

……

As Xuannv No. [-] plunged straight into the sky, there was a burst of cheers in the research institute!

Hearing the celebrations around him, Academician Cao Liangcai secretly took off his glasses and wiped his eyes.

how many years.

In the field of aerospace, Xia Guo finally surpassed the western powers in a real sense!

Before Cao Liang was happy, a siren sounded suddenly!

"Academician Cao! The speed of Xuannv No. [-] has suddenly slowed down a lot!"

"Xuannv-[-]'s flight path has deviated from the planned track!"

Chapter 74 Slow down... Slow down

Cao Liangcai's complexion changed drastically, and before he had time to think about it, he grabbed the radio on the podium and shouted loudly.

"Call Xuannv No. [-], call Xuannv No. [-], please answer!"

Soon, Bai Yixuan's replying voice came over the radio.

"Ground command center, Xuannv No. [-] received it."

There are responses!

It seems that there is no major problem...

Cao Liangcai breathed a sigh of relief, and hurriedly asked, "What's going on? Why did the plane suddenly slow down and deviate from the planned orbit?"

"..."

After a moment of silence, Bai Yixuan's slightly bitter voice came: "Report, Lu, Professor Lu is on the plane."

……

Back in time a few minutes ago.

The moment Xuannv No. [-] took off.

Lu Yongchang in the back row was firmly pressed against the passenger seat by the recoil.

After takeoff, the recoil is slightly reduced.

Just as Lu Yongchang breathed a sigh of relief and was about to say hello to the three drivers, a stronger recoil force pushed him back into the seat again.

Unlike when it took off, the acceleration this time came fast and urgent!

Not only that, Lu Yongchang felt that his sitting posture was also deflected by 90 degrees.

Under the influence of recoil and gravity, the blood all over his body rushed to his brain, and Lu Yongchang's face turned red instantly.

The consequences of a large amount of blood rushing into the blood vessels of the brain in an instant...

There was a chill in Lu Yongchang's heart.

It's not good to go on like this!

Waves of dizziness hit him, and the alarm bells rang in his heart.

He stretched out his hand, pressed the radio switch with difficulty, and said in the channel of Xuannv No. [-] team with difficulty: "Slow...slow down..."

"Fuck*3!"

Hearing the voice from the helmet radio, the three drivers trembled suddenly, and uttered a soul-stirring tone in unison.

Bai Yixuan's hand holding the joystick trembled violently, and even the fuselage carrying Xuannv No. [-] trembled violently.

"Fuck..."

The modal particles this time came from Lu Yongchang's mouth.

He suddenly regretted getting on this plane hastily.

Under the operation of the three pilots, the acceleration of Xuannv No. [-] gradually decreased, and the fuselage gradually returned to stability.

The fuselage has also returned to the normal range from an inclination angle close to 90 degrees.

"Huh... It's considered alive." Lu Yongchang tugged on the collar of his flight suit, exhaled slowly, and sighed softly.

"Professor Lu, we should say this..." Hong Fan in the left co-pilot seat turned around and looked helplessly at Lu Yongchang in the back row, "So, Professor Lu, why are you here?" side?"

"That's right, Professor Lu, do you know how dangerous it was just now?"

Xia Wanyi, who was in the passenger seat on the right, also joined the denunciation camp.

She looked at Lu Yongchang with a face of reproach, and said angrily: "Fortunately, the power of the Hall thruster was not high just now."

"If the power of the propeller is higher and the acceleration is higher, I guess you won't even have the chance to speak."

Lv Yongchang laughed lightly and coughed lightly: "Ahem!"

"I'm not here to go to space to see... This is also for my next research project!"

"As for how it got here... I designed this plane anyway, so I don't know where I can hide someone?"

While speaking, Lu Yongchang proudly patted his flight suit and safety belt: "Don't worry, I trained several times at that time!"

Three drivers: "..."

Just when the three of them didn't know what to do, Cao Liangcai's voice came over the radio.

"What's going on? Why did the plane suddenly slow down?!"

Bai Yixuan turned around and glanced at Lu Yongchang with a wry smile: "Professor, how should I answer?"

Unlike the three astronauts, the old god Lu Yongchang said on the ground: "Of course I told the truth to Lao Cao! Don't worry, nothing will happen!"

The wry smile in Bai Yixuan's eyes became stronger, then he turned around, pressed the radio switch, and reported the situation inside Xuannv No. [-] truthfully.

"...What the hell?!" In just a few seconds, Cao Liangcai's roar came again from the radio, "Why did that kid Lu Yongchang go to your side?!"

"What about others? Let him talk!"

"Ahem! Old Cao..." Lu Yongchang's eyes flashed with embarrassment, he reached out and touched his nose, and said softly.

"Shut up! Don't get close to me!"

The moment Cao Liangcai, who was still on the podium, heard Lu Yongchang's voice, he was in a bad mood!

"You, come down quickly!"

Lu Yongchang shrugged his shoulders, and responded calmly: "Old Cao, calm down, I just take a plane, is it necessary to be in such a hurry?"

Cao Liangcai laughed angrily: "Take a flight? You call this a flight?"

"This is the first test flight of Xuannv-[-]! If something goes wrong, how can I explain to Minister Hong and Councilor Li?!"

"Calm down...Old Cao, you have to trust the quality of Xuannv No. [-], and more importantly, you have to trust the skills of the three pilots!" Lu Yongchang said happily.

"No! Bai Yixuan, I order you to return to the voyage immediately and send Professor Lu down to me first!"
