After signing for eight years, he was exposed by the school beauty niece!

Then, Lin Yi took out the console next to the fighter and began to debug the data.

Su Yicheng and Lin Xuan, who were playing games on the side, glanced at Lin Yi from time to time, looking at Lin Yi's serious appearance, Su Yicheng muttered:

"Lin Xuan, I see that Xiaomei is particularly sincere this time, did those words just now make her feel that we are a little disrespectful to her, so she is stubborn?" If we can't fly for a while, we must also be ready to comfort the little sister and don't let her face be unbearable.

When Lin Xuan heard this, she also nodded and said with a smile: "Okay, I understand this, but Lin Yi should not really be angry with us, after all, she is our good sister!" Both

had a bad laugh.

Here, after Lin Yi was debugged, he walked towards Lin Xuan and Su Yicheng.

"Sister, you two are a little farther away, go to that tree, it will be a little noisy for a while, it's better to cover your ears."

The two smiled in their hearts, but did not say anything, very cooperatively walked to the big tree behind, and then leaned against the tree, quietly looking at Lin Yi and the fighter model beside her.

Then, Lin Yi also quickly took a few steps back, and pressed a button at the same time.

I saw blue flames suddenly erupt from behind the exhaust of the aircraft, and it was more than two meters long, longer than the fuselage.

Both of them were stunned at once.

Ah this!

What is this operation?

Isn't this model battery-powered? Why are you still flaming? Fuel-burning?

But how much fuel can such a small plane hold, didn't it burn out before it took off?

Both were puzzled.

But at this moment, Lin Yi pressed a button again.

Rumble!

A deafening roar sounded!

This sound is extremely penetrating, even the movement can be heard on the side of the city center, both of them subconsciously covered their ears, and after a while, the sound gradually weakened.

The two wanted to check the condition of the fighter model again, but they saw a wave of air and wind, surrounded by flying sand and rocks, hovering in the air like a tornado.

And the fighter model was not affected by the wind, along the straight route, directly ejected, and the speed gradually increased, after gliding for a distance, it was like a towering arrow, directly soared into the air, flying above the sea, and the altitude is still rising, and finally straight into the sky!

At this time, Su Yicheng and they were still holding the big tree tightly, they were almost blown over by the wind and waves just now, and their ears felt some tinnitus after that roar.

But these did not affect the shock in their hearts in the slightest, at this moment, the two with messy hair looked up at the plane in the sky, and the shock and joy in their hearts were indescribable.

At this moment, they are simply shocked, who would have thought that a model of a fighter with a thick shell and a bloated look could actually fly such a long distance, and recall the flying sand and stones just now and the long flame exhaust and huge roar when taking off, isn't this a sensational scene that can only be created by real fighters?

Both of their emotions are choppy and volatile.

Su Yicheng even jumped up excitedly, completely ignoring the dignified image of the beauty, and exclaimed excitedly:

"It actually flew!" And still jet flight, where can such a small aircraft model get so much energy! Lin Xuan, I'm not dreaming, am I?

"Yes, this kind of speed and huge energy drive, how can such a small fighter model withstand it, supposedly it should be directly melted, right?" Lin Xuan looked at the sky, also dumbfounded.

"No, Xiaoxuan, we blame Lin Yi, this is not a model, this is indeed an airplane!" At this time, Su Yicheng's eyes were firm.

When Lin Xuan heard this, he also nodded and said with a smile: "Well, only airplanes can achieve this kind of spectacularity, no, it's a fighter!" The

two stared at the fighter hovering in the sky, and for some reason, a sense of reverence arose.

They don't dare to underestimate this fighter, although it is small, its energy is not small, who knows if it will become a terrifying black technology weapon if it is loaded with miniature ammunition.

At this time, even if the fighter was flying in the air, there was still a huge roar, and Su Yicheng and Lin Xuan couldn't help but dance with excitement as they watched the fighter draw a brilliant arc in the air.

Subsequently, the fighter gradually descended, and even flew on the surface of the water, stirring up layers of waves, but not a drop splashed on the fuselage, because the speed was too fast, and the speed of splashing was less than a fraction of the flight speed.

The two watched the fighter fancy flight, and their hearts were shocked.

It's too fast, sometimes so fast that their eyes can't catch it.

"Sister Yingcheng, how fast does this have to be? I feel like I can only see an afterimage just now. Lin Xuan put his arm around Su Yicheng and said with an excited expression.

Su Yicheng let Lin Xuan hold him, looking up at the sky blankly, he didn't ease up from the shocked emotions for a long time

, for a long time, Su Yicheng slowly said:

"This thing is really outrageous, I feel that the barren knowledge limits my imagination, let's ask Lin Yi."

Lin Xuan also nodded and pulled Su Yicheng towards Lin Yi, who was controlling the fighter flying in the rear.

When the two came to Lin Yi's side, they asked eagerly:

"Little sister, this plane... No, what is the flight speed of a fighter? This is also too fast!

Lin Yi was also a little shocked by the flight performance of the fighter at this time, although he had expectations, but he did not expect that the degree of completion was so high, and the fuel consumption speed was lower than expected.

It's just that she didn't expect that Su Yicheng and they ran over, and the first thing they asked themselves was actually to ask how fast was flying?

"Sister, aren't you curious about what material this plane is made of? What fuel is used, and what black technology is used to make it fly? But they just ask me how fast I fly? Lin Yi looked at the two and said suspiciously.

Su Yicheng smiled and patted Lin Yi's shoulder and said: "Little sister, we don't understand those things, in addition, I have to apologize to you, just now my sister misunderstood you, it is indeed an airplane, but you tell me the flight speed first, I really want to know."

Lin Xuan also nodded and said apologetically: "My pot, blame me for having too little knowledge, I never thought that an airplane could be made to a length of more than one meter!"

Lin Yi glanced at the two, showed a shallow smile, and said in a soft tone: "Okay, I didn't say I was angry with you, this flight speed, there is something on the console, this, you can take a look." When

Su Yicheng and Lin Xuan heard this, they leaned over and looked down at the controller screen in Lin Yi's hand.

Above there is a written speed parameter that says the number 7.

But there are no units behind.

The two were stunned and looked at Lin Yi one after another.

"Sister, what does this 7 mean?" Lin Xuan wondered.

Su Yicheng gasped sharply and boldly guessed: "Lin Yi, this 7, is it seven hundred kilometers per hour?" "

Because normally, when there is no standard unit, the standard is kilometers per hour.

In Su Yicheng's impression, the speed of the passenger plane is five hundred to one thousand kilometers per hour, and seven hundred kilometers per hour obviously reaches the normal flight speed of the passenger plane, and it is also a fast speed.

But it still doesn't feel right, the flight speed I just saw should be much faster than that of ordinary aircraft, it should be measured according to the speed of the fighter, then how can it be close to supersonic, almost more than a thousand kilometers per hour, right?

"Not seven hundred kilometers per hour." At this moment, Lin Yi replied.

"It's Mach seven, which means seven times the speed of sound."

"Seven times the speed of sound, that's about 8,500 kilometers per hour."

Mach Seven?

Su Yicheng and Lin Xuan were shocked again, this is also too fast, no wonder it was a little difficult for them to catch the figure of the fighter with their naked eyes just now.

This is also much higher than they expected.

"Seven times the speed of sound, what the hell is this concept!" Su Yicheng felt that his brain was buzzing.

Lin Xuan quickly took out his mobile phone and checked it.

As soon as he looked at the data, he immediately exclaimed:

"I'm dripping obediently, our fastest fighter in Huaxia now is only Mach 2.2 at a speed, about 2,500 kilometers per hour, compared with Lin Yi's fighter, it is a full 6,000 kilometers per hour, this..."

What does this mean? It means that Lin Yi and the aircraft they built for experiments killed the fastest fighter in Huaxia in seconds!

Who can stand this!

Lin Xuan and Su Yicheng are speechless at this time, today they don't know how many pounds to eat, at least dozens of tons, if they don't have intact heart function, they are estimated to get oxygen from the hospital at this time!

I can't really come here to play if I have a bad heart.

......

At the same time, Ye Qing woke up leisurely, looked down at the scene outside the window, and looked at this realm, it should be almost to Jinling.

Then, he suddenly heard a loud noise, and then he looked out the window, and saw a small object bursting into the air.

Although it was far away from them, it made a loud noise, and at this time, the small object only stayed in front of Ye Qing's eyes for a few tenths of a second, and then it broke through the clouds in front of them, and soon disappeared.

Ye Qing couldn't help but be a little shocked.

This, he is sitting on the plane now, and he can't see the UFO figure just now.

Using the plane as a reference, that thing overtook it almost instantaneously, how outrageous is this absolute speed?

Ye Qing: "..."

???

What the hell is this thing that swoops and passes?
