53: Mom, a big fireball just flew by.

That’s right.

The two most important technologies the system rewarded Su Yu with were Level 3 Propulsion and Pulse Detonation.

Pulse Detonation had already been demonstrated during the initial propulsion ignition, with the instantaneous detonation producing an acceleration effect that could easily reach supersonic speeds.

As for Level 3 Propulsion, it was also the most crucial part of the rocket model's design.

After all, this was the third task issued by the system.

The higher the social recognition rating displayed by Level 3 Propulsion, the higher the completion of the task, and naturally, the better the rewards obtained.

Therefore, Su Yu also put a lot of effort into designing and using this technology, even specifically asking Professor Tang Zhenggang to procure genuine aerospace materials for it.

If ordinary materials were used, even with Level 3 Propulsion technology, the maximum height the rocket model could reach would be no more than a few thousand meters.

But it was precisely this unintentional act that allowed the rocket model to truly have the ability to soar to a height of ten thousand meters.

After the dongfeng no. 1 prototype rocket reached an altitude of about 9,000 meters, its propulsion speed began to decrease for the first time.

However, this was not because the solid fuel was about to run out, but because Su Yu deliberately controlled the fuel release.

At this distance, the rocket only needed one Pulse Detonation to instantly reach an altitude of ten thousand meters. This is not only the optimal cruising altitude for jet planes but also the optimal flight altitude for rocket missiles.

Now that the rocket had reached its optimal flight altitude, the next step was to locate the exact positions of flight m734 and the unknown bird creature.

Based on the GPS signal source obtained from the flight m734 pilot just now, he decisively activated the weather radar detection.

One can only say that everything was arranged by fate!

Su Yu was very lucky. After the rocket model cruised at an altitude of 9,000 meters for about ten seconds, he discovered two small red dots on the weather radar... In the live stream.

At this moment, all cameras were focused on his operation screen.

Over two hundred thousand viewers stared intently at the broadcast screen, afraid of missing this critical moment.

When the two faint red dots appeared on the weather radar detection screen, everyone's expressions became excited.

"They found it! I didn't expect the Streamer to actually find it!!!"

"I only have one word to say right now: Awesome! It's so damn awesome!!!"

"From an unsubstantiated altitude of ten thousand meters, accurately locating and locking onto the position of flight m734 within a mere twenty seconds, the Streamer's GPS positioning technology is probably not ordinary level."

"Come on, Streamer! The countdown is three minutes, only a little over one minute left!"

"The crisis hasn't been resolved yet, Streamer, don't let your guard down!"

In the live stream, reminder messages from the bullet screen were incessant.

However, Su Yu couldn't see any of this.

Because at this moment, his attention was entirely focused on operating the rocket model.

The moment the weather radar detected flight m734, Su Yu had already calculated the distance between the rocket model and the plane through data.

At this time, the rocket model was approximately 30 kilometers in a straight line behind and to the side of flight m734.

Calculating based on the dongfeng no. 1 prototype's flight speed of 500 meters/second and the plane's cruising speed of 350 km/hour, which is 97 meters/second, the rocket model would need approximately 75 seconds to catch up to the plane.

But to ensure the plane would not be affected by the aftershocks of the explosion.

The plane needed to be at least two to three thousand meters away from the center of the explosion for safety.

In other words, dongfeng no. 1 prototype had to catch up to flight m734 within 75 seconds and overtake it! Then, it had to shoot down that large bird in front of the plane in advance.

Otherwise, it would still cause serious impact on the moving plane.

There's no time left!

After simulating the final outcome in his mind, Su Yu no longer dared to hesitate for a moment, controlling the rocket to adjust its flight direction and pressing the last red button!

Level 4 Propulsion!!! Activate!!!

Boom!

Accompanied by black flames erupting suddenly from the rocket's tail!

The last booster rocket was ignited.

At the same time, the remaining aerodynamic fairings at the tail were instantly consumed by the terrifying high-temperature flames.

This was dongfeng no. 1 prototype's final acceleration!

And it was dongfeng no. 1 prototype burning out all its acceleration!!

The iron lump, originally one to two meters tall and weighing three to four hundred jin, had, after Level 3 Propulsion, been reduced to only the pointed rocket head at the very front. The boosters behind had long since completed separation and fallen off after their fuel was exhausted.

At this point, the rocket model's weight had sharply decreased to less than 100 jin!

Under the same acceleration, the smaller the mass, the faster the speed! To make the rocket fly at its fastest speed, Su Yu even burned off the aerodynamic fairings of the tail fin.

In fact, the current dongfeng no. 1 prototype can no longer be called a rocket model!

It can only be called a burning iron ball!

Yet, it was precisely this glowing red iron ball that became the key to saving over a hundred lives on flight m734.

Countdown 60 seconds... The burning iron block flew diagonally upwards with a speed breaking the sound barrier! The iron block was already glowing red! If it weren't for the super-strong aerospace-grade alloy material, it would have probably been burned to charcoal long ago!

Countdown 50 seconds... Inside the flight m734 cockpit, Zhao Long and Zhang Qiandong had already closed their eyes in despair.

Perhaps, this was fate!

What cannot be escaped, ultimately cannot be escaped, and they had tried their best.

Countdown 40 seconds... According to the weather radar display, the plane was getting closer and closer to the flashing small red dot ahead. The incessant beeping alarm, like a heart monitor in a hospital room, cold and merciless, recorded the countdown of life.

Countdown 30 seconds... Suddenly, another faint red dot approached from the plane's diagonal rear at an extremely fast speed! Its speed was so great that people didn't even have time to react!

Countdown 20 seconds... Zhao Long and Zhang Qiandong, through the glass in front of the cockpit, vaguely seemed to see a small black dot flying from the horizon, coming straight towards them... Inside the cabin.

A little girl with pigtails was sitting by the window at this moment.

The little girl, just woken up, curiously pressed her small head against the thick glass, trying hard to see the scenery outside.

However, the next second.

A burning black fireball flashed past her eyes with a "whoosh."

The girl's eyes widened, full of wonder.

"Mommy, mommy, look! It looked like a big fireball just flew by!! So cool!"

The little girl's sudden excited shout immediately drew dissatisfaction from other passengers around her.

The girl's mother quickly pulled the little girl back from the window, apologizing apologetically to the affected passengers around her.

"I'm sorry, I'm sorry,"

"The child is talking nonsense, please don't mind her."

Then, with a hint of annoyance in her eyes, she sternly told the little girl: "Tuanbao, don't talk nonsense. Look, you've disturbed the uncles and aunties' rest!"

"Besides, how could there be a big fireball next to this plane?"

The little girl pouted and pointed out the window.

"Mommy, Tuanbao isn't talking nonsense."

"If you don't believe me, see for yourself!"

The girl's mother looked out the window in confusion. The next second, her gaze froze!
