Take off

"What!"

The moment Cao Liangcai heard the researcher's words, he felt a buzzing in his head.

"How could a grown - up person disappear?!"

Cao Liangcai stared at the researcher in front of him with bloodshot eyes and roared impatiently, "Have you checked all the toilets in the research institute?"

The researcher was on the verge of tears.

Facing Cao Liangcai's questioning, he shook his head with a bitter face. "I... I've checked all of them, but I just can't find Professor Lü."

"Not to mention Professor Lü, there's not even anyone in these toilets in the research institute!"

Cao Liangcai took a deep breath, turned his head, and shouted, "Surveillance! Quickly pull up the surveillance for me!"

"Academician Cao, there's one minute left until the scheduled take - off time!"

A reminder came from the side.

Cao Liangcai gritted his teeth and let out a heavy sigh. "Forget it! Let's deal with the matter of Xuannü - 1 first!"

"Since Professor Lü isn't here, I'll be in charge of the entire test - flight process of Xuannü - 1!"

As he spoke, Cao Liangcai reached out and picked up the wireless microphone on the command console. "Xuannü - 1, attention!"

"Thirty - second countdown to take - off!"

...

Inside Xuannü - 1.

The three pilots stared intently at the instrument data on the console in front of them.

A figure in a white flight suit quietly appeared in a corner at the rear of the cabin.

As the camera zoomed in, the face inside the helmet was actually Professor Lv Yongchang, who should have been in the toilet!

Lv Yongchang tiptoed to the passenger seat behind the main pilot's seat.

Because the seats in the three pilot positions were relatively tall, creating a certain blind spot in the field of vision, the three pilots didn't even notice that there was an extra person in the seat behind them!

He skillfully grabbed the seat belt on the seat and strapped it around himself.

A look of satisfaction appeared in Lv Yongchang's eyes.

Not bad, all his furtive training sessions were worth it.

"Click!"

The sound of the seat - belt buckle was particularly loud in the silent cabin.

Lv Yongchang's body stiffened suddenly, and his eyes stared nervously at the three pilots in front of him.

"Gulp..."

Lv Yongchang's Adam's apple moved slightly as he swallowed a mouthful of saliva.

The plane hadn't taken off yet. Once he was discovered...

He was 100% certain that he would be kicked off the plane!

After a few seconds, seeing that the three pilots' expressions remained normal, Lv Yongchang let out a slight sigh of relief.

It should be the earphones in the helmets that blocked the sound just now.

"...Thirty - second countdown!"

Lv Yongchang's eyes moved slightly.

It's about to take off!

A flash of excitement appeared in his eyes.

"Xuannü - 1 copies!"

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

"Preparing to start the Hall thruster!"

"..."

One announcement after another came through the earphones in the helmets.

Lv Yongchang couldn't help but feel a little nervous.

Even in two lifetimes, this was his first time taking a spaceplane and entering space!

"Three, two, one, take off!"

With Cao Liangcai's command, Bai Yixuan in the main pilot's seat pushed the joystick on the console with a determined look.

A slight tremor came from under his feet.

The Hall thruster started.

The moment this thought flashed through Lv Yongchang's mind, he felt himself being pressed firmly against the seat back by a huge force!

...

In the DouSha live - streaming room.

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

"I've been waiting so long!"

Just when the netizens were getting impatient, a steady command voice came.

"Thirty - second countdown to take - off!"

Hearing this command, the netizens in front of the computers perked up.

In the live - streaming screen, a faint blue flame slowly appeared at the tail of the Xuannü - 1 spaceplane.

"Damn! Damn! What's that?"

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

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

"Somebody, put me on the fire to roast and liven things up!"

The thirty - second waiting time passed in a flash. With the take - off order given, the faint blue flame at the tail of Xuannü - 1 suddenly increased several times!

The next moment, pushed by the Hall thruster, Xuannü - 1 began to accelerate slowly.

In the blink of an eye, it reached the end of the runway!

With the nose of the plane tilting up, Xuannü - 1 leaped into the blue sky!

The moment this scene was recorded by the camera, there was another outburst of excitement in the live - streaming room!

"It took off! It took off!"

"Damn, this tail flame, this appearance... Need I say more? A ten - year fan of Xuannü - 1 is here uninvited!"

"They all say Xuannü - 1 is a spaceplane, but where is the destination of this test flight? It can't just be a trip around the sky, right?"

The live - streaming host seemed to have seen this bullet comment and explained softly, "The destination of Xuannü - 1 this time is the geosynchronous orbit 36,000 kilometers above the Earth's surface."

"Whoa... It's actually the geosynchronous orbit!" Zhao Zijie, sitting in front of the computer, took a sharp breath.

Taking off from the Earth's surface and directly heading for the geosynchronous orbit... The power of Xuannü - 1 was probably more exaggerated than anyone had imagined!

Not to mention how many satellites of other countries were in the geosynchronous orbit, nor whether Xuannü - 1 was equipped with weapons. Just dropping a tungsten rod from it would have consequences that most countries couldn't bear!

Under the shooting of the high - speed camera, the figure of Xuannü - 1 clearly appeared in the live - streaming screen.

After taking off, the faint blue flame at the tail of Xuannü - 1 increased a bit more.

Different from ordinary chemical - fuel engines, the exhaust of the Hall thruster was high - speed plasma at hundreds of millions of degrees Celsius.

Therefore, within the atmosphere, the tail flame of Xuannü - 1 was particularly spectacular!

The ten - meter - long faint blue flame was densely filled with countless Mach rings!

Before the netizens could send out amazed bullet comments, the nose of Xuannü - 1 suddenly pulled up.

Pushed by the Hall thruster, the entire plane climbed upward at a slope close to 90 degrees!

"Boom!"

A loud noise came from the sky!

A beautiful sonic boom cloud instantly appeared around the fuselage!

The moment the sonic boom cloud appeared, the number of bullet comments in the live - streaming room skyrocketed dozens of times!

"Damn, damn, damn!"

"Mom, come out and see God!"

"Is this the speed of sound already? Goodness, the maneuverability of this Xuannü - 1 is too strong!"

...

As Xuannü - 1 shot straight into the sky, cheers suddenly rang out in the research institute!

Listening to the celebration sounds around him, Academician Cao Liangcai secretly took off his glasses and wiped his eyes.

How many years had it been.

In the field of aerospace, Xia Country had finally truly surpassed the Western powers!

Before Cao Liangcai could be happy for long, an alarm suddenly went off!

"Academician Cao! The speed of Xuannü - 1 has suddenly slowed down a lot!"

"The flight path of Xuannü - 1 has deviated from the planned orbit!"
