The real heavenly falcon immediately set off to return to the school, couldn't stop it, threw off Yushin and a few people, and flew to the sky with his own dancing technique, flying towards Kyoto at full speed. Pen % fun % Pavilion www.biquge.info

"Boom!"

Suddenly there was a deafening explosion in the sky, and everyone instinctively covered their ears, and everyone was shocked, it felt like a mortar exploding at close range, causing panic.

It can be seen that a white cloud has formed in the original location of the Falcon and that the Falcon is gone.

"Sonic Boom Cloud!" Youxin was stunned, I have seen Wikipedia before, when the speed of the object is close to the speed of sound, it will gradually catch up with the sound waves emitted by itself, this phenomenon mostly appears in the body of supersonic fighters, after breaking through the speed of 340 meters per second, due to the compression of the air by the fuselage, it can not spread rapidly, and will gradually accumulate on the windward side of the aircraft and its nearby areas, and finally form a sudden change surface of physical properties such as pressure, temperature, speed, and density in the air, the shock wave surface.

The shock surface will increase the drag of the air on the aircraft, commonly known as the sound barrier.

The shock wave surface formed by the aircraft entering supersonic flight is a highly concentrated surface of acoustic energy, so it is also called a sound cone, which is a short and extremely strong (may exceed the hearing of the human ear) explosion sound in hearing, so it is called a sonic boom or sonic boom.

"Liar, huh? The boss has broken through the speed of sound!? The monkey opened his mouth wide in horror, this physical phenomenon has only been heard of, and he has never seen it with his own eyes, but he didn't expect the real Falcon to do what a supersonic fighter can do, is this still human?

"The time machine.... Does this thing really exist? "Stone doesn't really believe in the True Celestial Falcon's plan to travel back in time on a time machine.

"The boss said yes, that's yes! The teachers in our school are all Crouching Tiger, Hidden Dragon, the biology teacher is Orochimaru, the physical education teacher is a ghost, the alchemy teacher is Alice Phil, and the physics teacher is Maise Hongrisu! ”

The True Sky Falcon opened the Triple Realm King Fist and hurried, and the speed was also three times faster, and people saw the red streamer flying quickly, but they couldn't see what it was, and it was fleeting.

As the Falcon flew at full speed, the scenery in front of it quickly changed and narrowed, and it arrived in the mountains in the distance in the next second, passing from the top of the mountains and crossing the entire region, which was too fast.

The Falcon couldn't hear any sound when it was flying, he had broken through the speed of sound, and the sound couldn't keep up with his speed, so the Falcon wondered if he was deaf.

It took a few hours to return to Kyoto from Zhenxin Town, but it was compressed to just a few minutes by the True Sky Falcon, which is of course, 340 meters per second, 1224 kilometers in an hour, and you can get from Guangzhou to Shanghai.

In a hurry of 100,000,True Amazaka soon returned to school,Found physics teacher Maise Red Risu,Speaking of this celebrity,That day the name was well-known,Victor Condoria University Brain Science Institute researcher,Although specializing in brain science,But the attainments in physics are also very high,You can often see magazines and newspapers publish her news。

The most important thing is that she is the creator of the time machine, and she has been secretly researching it for a long time, because of the great influence, so there are only a few people who know this news, and the real Falcon happens to be one of the insiders.

However, the true falcon still maintains a skeptical attitude towards time travel, and does not take it too seriously, which is too magical and unscientific.

This time, in order to change the past, the true heavenly falcon can only grasp the last straw, and the dead horse becomes a live horse doctor, and any possibility must be tried.

In the staff office, Makise Hongliqi was brewing coffee, while flipping through the recent academic reports of the scientific community, Matenfala suddenly burst in out of breath and said, "Teacher, please let me use the time machine!" ”

"Poof!" Makise Hongliqi was choked, and after coughing a few times, she relieved herself: "What did you say?" ”

"I'm going back in time, please." True Celestial Falcon folded his hands and pleaded sincerely.

The long-haired maroon glanced at the real Falcon with her unique and magnificent purple eyes, she knew that the boy in front of her was serious, so she stood up and said, "Can you explain to me the reason?" ”

"A friend of mine and a small town resident are dead, destroyed by falling meteorites, so I want to go back in time and change that ending." Matenfala told Makise Honglisu all the causes and consequences, there is nothing to hide, he is to save people.

After listening to Matenfala's statement, Makise Red Risu was silent, she could understand her determination to save people, but time travel has always been a scientific experiment that has not been verified, and Maise Red Risu can't hastily agree, that is a field that humans should not set foot in easily.

"The time machine is still in the testing and tuning stage, there are all kinds of unpredictable risks, if it fails, you may die, or you may be transported to an unknown dimension, are you willing to go?" Makise asked Makita lightly, asking him if he had considerable consciousness and whether he could teleport Matenfala back to the past, but she was not absolutely sure.

Hearing Makise Hongriqi's words, Matenfala was a little shaken, these words were too scary, and people always had awe and fear of the unknown realm.

"Wait, I'll write a suicide note first."

Makise Red Liqi originally thought that the real heavenly falcon would retreat, but he didn't expect him to choose the most realistic way to write a suicide note!? This is the determination to be ready to die, considering the instability of time travel, it is necessary for the real Falcon to explain the aftermath, in case he can't come back, what will happen to his family?

It takes courage to challenge the unknown possibilities, and the true heavenly falcon can make such a decision, which has to be admired, how many people can do it so chic?

Using pen and paper, Matenfala wrote several long suicide notes and left them for friends and family, one for each person.

When he was done, Matenhaya breathed a sigh of relief, felt a little more at ease, and handed a few letters to Makise and said, "Teacher, if something happens to me and I don't come back, please pass these letters to my family and friends." ”

Makise Hongliqi hesitated for a moment, but still solemnly accepted it, she wouldn't say anything before thinking twice, this was the decision of the real heavenly falcon.

"I see, I'll pass it on for you."

"Thank you, teacher, can you take me to the time machine now?"

"Come with me."

Makise put on her research gown and entered the school's underground facility with Matenha, and after a series of identity verifications, the two took the elevator to the physics laboratory, which was hidden 50 meters underground.

Before that, Matenfala had never known that there was such a large space under the school, it was like a science fiction movie.

Walking through the research room, where you can hear the echo of footsteps, the space inside grows larger and larger, and gradually, a large spherical machine filled with various pipes and wires comes into view.

"That's the time machine." Makise put her hand in the pocket of her white coat and introduced her masterpiece to Matenhaya.
