Hence, everyone was even more shocked.

Some people even felt that they could not breathe.

When the plane finally returned and stopped in front of them, they still could not calm down for a long time.

“Oh my god… Is… Is this really a fighter jet?” Liu Yun held his chest and asked.

Ye Xuan rolled his eyes at him and deliberately said, “This is just an airplane model.”

This was indeed just an aerial model. Due to the size limitation, it could not be filled with more fuel so that it could fly further. There was no space to accommodate the pilot, nor was there a weapon.

This time, it was Liu Yun’s turn to insist that this was a fighter jet. “Brother Ye, don’t tease me. I was wrong just now! This is a fighter jet. Oh my god! Is there a plane stronger than this in this world? The planes in videos of military exercises I saw weren’t so agile! Brother Ye, you’re too handsome!”

Ye Xuan scolded jokingly, “Didn’t you not believe me just now? If you don’t believe me, I won’t let you play with it later.”

“Brother Ye, I was wrong, I was wrong. Please let me play with it! This is simply the dream of all men! I believe it now. In the future, I’ll believe anything Brother Ye says! Even if Brother Ye says that he wants to bring the moon home to play with it, I’ll believe it!” Liu Yun hurriedly begged for mercy.

“That’s more like it… Then I’ll reluctantly bring you to the control panel to control it,” said Ye Xuan.

“Brother Ye, that was automatic driving just now. I didn’t see you controlling it.” Speaking of the control panel, Liu Yun didn’t see Ye Xuan standing in front of the control panel just now.

Ye Xuan didn’t answer. Instead, he brought them to the control panel.

“It’s controlled here with AI support. Most of the flight lines were designed in advance, so there’s no need to operate the plane too much,” explained Ye Xuan.

Liu Yun craned his neck to look at the console. It was all in English. Then, Liu Yun looked at the speed parameters and was stunned. He asked Ye Xuan, “Brother Ye, what does this 4 mean?”

Could it be 400 kilometers per hour?

“That’s not right. I feel that it’s so fast. That plane doesn’t just have this speed, right?”

Everyone began to guess.

“That’s four times the speed of sound, Mach 4.”

Seeing that everyone had different opinions, Ye Xuan didn’t beat around the bush and directly revealed the answer.

Mach 4?!!!

Liu Yun was shocked again. Then, a young master beside him suddenly raised his voice and said in an extremely shocked tone, “Four times the speed of sound is more than a thousand meters per second!”

This!

Everyone was shocked again. Then, they took out their phones and searched.

Currently, the fastest plane in China could only reach supersonic speed, with a speed of 300 to 400 meters per second.

What did this mean? It meant that the plane Ye Xuan built instantly killed the fastest fighter jet in China!!!

“Oh my god, can such a small thing have such speed? Brother Ye, if you make a bigger plane, can it be as fast as this?” Someone asked.

“Yes. It might even be faster,” replied Ye Xuan.

The answer was yes.

As this was an airplane model with a reduced ratio, relatively light metal that was not that durable had been used. If the plane was made according to the blueprint, the plane would be stronger and the speed it could withstand would naturally be faster.

Everyone was shocked when they heard this.

If the outside world found out, the world outside would probably change…

What kind of black technology was this?!

…

At the same time, on the other side.

His Eighth Sister Ye Qian was preparing to buy seafood for Ye Xuan to cook at the beach.

“Wow, the prawns here are still fresh! They’re so big!” Ye Qian thought about tonight’s menu as she chose the seafood.

As her culinary skills had improved greatly recently, she felt a sense of accomplishment when cooking. In addition, Ye Xuan also expressed his desire to eat his sister’s dishes. Therefore, Ye Qian had put in more effort in cooking recently and specially went to the seafood market to buy the freshest ingredients.

She decided to make braised prawns tonight!

As she walked forward, Ye Qian saw that the scallops were quite fresh, so she added garlic vermicelli scallops on the menu.

She had yet to start cooking, but she was already craving it.

Ye Qian quickly bought all the materials she needed and placed them in a cloth bag before walking out of the seafood market.

The moment Ye Qian walked out of the market, a loud roar sounded in Ye Qian’s ears, making her ears hurt.

Therefore, Ye Qian subconsciously began to search for the source of the sound.

When she looked up, she saw an unknown flying object flying across the sea at an extremely fast speed. For a moment, Ye Qian could not catch sight of it.

The flight trajectory was simply unreasonable.

No matter how hard Ye Qian tried to focus, she could not see what it was!

Therefore, Ye Qian was shocked!

It had to be known that she was in charge of the strengthening and maintenance of fifth-generation aircrafts in the Chinese Academy of Sciences. Naturally, she had seen the speed of fifth-generation aircrafts.

Those were the fastest fighter jets in China, the fifth-generation aircrafts!

However, its speed was far inferior to the unidentified flying object from before.

What was that just now?!

That speed was at least Mach 2!

In an instant, Ye Qian was filled with all kinds of doubts.

...

Was the research institute testing a new plane?

That was impossible. She had only been home for a few days. The progress of her colleagues was not that fast.

Could it be that the enemy country’s recent invisible machine had come to detect them?

There was no need for the plane to fly so openly by the sea, right? Wouldn’t it be destroyed immediately?

No matter how she thought about it, she could not figure out what it was. In the end, Ye Qian even suspected that it was an unidentified flying object of an alien.

She wanted to look for that thing again, but she couldn’t find it at all.

Ye Qian was stunned on the spot.

The roaring sound in her ears could no longer be heard.

That was definitely not an illusion!

Therefore, Ye Qian immediately called the Chinese Academy of Sciences and explained the situation.

“What, are you saying that there’s an unidentified flying object?”

...

“Yes, but the speed is too fast. I can’t see what shape it is. Its speed is at least Mach 3 to Mach 4. Its speed is definitely above that of a fifth-generation aircraft.”

“Where did you see it?”

“At the beach in Jinling… Many people saw it. I happened to buy seafood there on my vacation…”

“Did many people see it?”

“Yes.”

“Alright, I understand. I’ll verify it first.”

After hanging up, Ye Qian’s heart was still beating wildly.

She had studied fifth-generation aircrafts for so long and thought that she had mastered the top technology in the world. Now, something suddenly appeared and broke her common sense. That feeling… was really uncomfortable.

…

At the same time, in an independent building in Jinling Airport, an alarm immediately sounded!
