Signed in for eight years, exposed by the school beauty's niece!

"You are so confused, Lin Yi, can you touch this kind of thing? If you like to do this, you should go to an aircraft manufacturing company to work. It's different if you do it privately."

"Yes, sister, stop it quickly. If you don't have legal procedures, you can't fly it. You need a flight route and a license. What if there is a problem with the parts and an accident happens?"

Su Qingcheng and Lin Xuan both persuaded her.

Lin Yi suppressed her laughter and comforted her softly: "Look at how nervous you are. I told you that there is no problem. You will know after you see it."

Su Qingcheng and Lin Xuan looked at Lin Yi, feeling helpless.

The queen is not anxious, so how can the concubines like them be anxious?

They can only stand aside and wait, taking one step at a time.

After a while, a large express delivery logistics truck that can go anywhere appeared in the distance. Everyone looked closely and saw that the express delivery truck was slowly driving towards the open space.

Soon, the express delivery truck stopped in front of everyone.

Then, several staff members got off the car and opened the carriage. Several staff members went in to move things.

One of the staff members looked at the three people and asked:

"Which one of you is Miss Lin Yilin? You have a courier."

Lin Yi responded: "I am."

"Okay, please wait a moment."

Soon, several staff members got off the carriage, pushing a cardboard box that was more than one meter long and wide and about half a meter high.

It looked very troublesome.

Lin Yi signed, and the courier staff put the heavy box here, and then drove away.

"Is this an experimental instrument?"

"When will the plane arrive?"

Lin Xuan and Su Qingcheng looked at the box and asked subconsciously.

Because the box was so small, they naturally thought that it was not the plane that Lin Yi said.

"Open it and you will know." Lin Yi smiled.

As she said that, Lin Yi cut the rope on it with a knife, and then tore off the sealing tape of the cardboard box.

The carton was opened, and Su Qingcheng and Lin Xuan stared with wide eyes, looking inside the carton with great expectation.

After seeing what was inside, the two were shocked.

After looking at the carton and then at Lin Yi, the two were speechless for a while.

At this time, they had only one idea, to tie Lin Yi to the sofa and torture her at night.

This is so weird...

"Lin Yi, you call this a plane?"

"I can recognize the word model after the word plane."

Then, the two pointed to a fighter model more than one meter long in the box and complained.

The appearance of this model is very realistic, with a silver-white color as a whole. The fuselage adopts a streamlined design, with wide trapezoidal wings on both sides, and fuel tanks hanging under the wings. There are multiple air intakes on both sides of the fuselage for storing energy for the engine. The nose is made of carbon fiber, and the fuselage is made of magnesium-aluminum alloy. It is worth mentioning that the appearance curve of the fighter model is extremely smooth, and it looks like a golden eagle, with 360 degrees of beauty.

If it wasn't only one meter long, anyone would think it was a real fighter.

"Wow, don't tell me, this model is so exquisite." Su Qingcheng reached out and touched the fuselage, which felt smooth and silky.

"Yeah, sister, you said it was a model earlier, I was scared to death just now." Lin Xuan also echoed.

Lin Yi said helplessly: "This is the plane!"

"Okay, sister, don't fool us, it's just a model, if you insist on saying it's a plane, then we can't do anything."

"Sister, have you watched your sister Qingcheng's live broadcast too much, and now you have learned to brag, I don't believe that you, a woman who wants to be a scientist, don't know that this is a model?"

"You deliberately omitted the word model to tease us, right? Sister, liars have to swallow a thousand golden needles."

They thought Lin Yi was talking about a real fighter, the kind of huge thing that can carry people and fly around in the clouds and fog.

I never expected that the result would be such a small thing. To be honest, it was really despairing.

But it also made them feel more at ease. If it was a real plane, they would have a hard time controlling it, and they would have to worry about the problem of the way it came. Now such a small thing should only be able to fly. It will run out of power before it flies far. If it falls down a few times, it will probably die on the spot.

But this is also in line with their expectations. After all, it is reasonable to make this kind of model by personal strength.

But the two of them took a closer look and it seemed to be made of iron sheet. Although it was not big, it should be relatively heavy. This small engine could notIt is still unknown whether this iron model can be driven to fly.

"Hey, you should make a lighter plastic or resin shell. This thick iron shell design is forcibly increasing the difficulty of flying. It can't fly at all, or it can't fly far even if it is barely driven." Su Qingcheng couldn't help but sigh.

For a moment, Su Qingcheng felt a little boring. This trip was in vain. She had seen a lot of aerial photography models. This fighter model, apart from being beautiful, seemed to have low practicality, and it couldn't even fly.

"Yes, try it quickly. If it can't fly, forget it. Let's go home after the process. Tonight, Lin Yi, you will be responsible for cooking and washing dishes, and then treat us to a massage and spa. The sisters will forgive your teasing today." Lin Xuan urged.

"Well, hurry up, my legs are numb. I've been standing for so long, and there's no place to sit."

If it weren't for Lin Yi being their sister, Su Qingcheng and Lin Xuan would have left long ago, but the two of them didn't have much expectations, so they just wanted to finish and go home early.

Hearing the two people's complaints, Lin Yi just smiled, but she didn't rush to take off. Instead, she took out the instrument from her backpack and began to check carefully. First, she checked the reserve of aviation fuel, and then checked whether the fuselage was damaged...

Su Qingcheng and Lin Xuan on the side were stunned when they saw Lin Yi's particularly serious and cautious look.

What does this mean?

Is it necessary to be so fancy when playing with a model?

"Sister, it's almost done. It's not a real fighter. Is it necessary to check it so carefully? Try to see if it can fly first." Lin Xuan's tone was a little anxious.

Seeing Lin Yi doing it slowly, she was very anxious.

Su Qingcheng even joked: "Little sister, don't be embarrassed if you check it for half an hour and it doesn't fly. Are you sure it can fly?"

Lin Yi said helplessly: "Why would I test it if it can't fly? Do you think I built it for fun? Don't worry, it can fly, but you have to do the preparations well. This thing is very precious. If there are any defects that are missed and not noticed, it will greatly affect the flight speed and may also cause accidents."

The two shook their heads and smiled bitterly when they heard it.

"How can it fly? Don't be funny, little sister, I have never seen such a simulated engine model that can fly. This is okay to put in an art gallery for people to watch. If it wants to fly, it has to be a light and small one like unmanned aerial photography." Su Qingcheng said with a firm tone.

Lin Xuan also nodded and said with a sly smile: "Sister Qingcheng, why don't we go back and have a meal first? We might just finish the inspection later and witness the fighter jet flying."

Both of them thought Lin Yi was joking and it was really a fantasy.

As they talked, they had already found a clean stone slab, put their coats on it, and sat down.

Afterwards, the two ignored Lin Yi and took out their phones to play a free-for-all.

And Lin Yi didn't care about her sisters' misunderstanding. She completed the pre-flight inspection step by step, then took back the inspection equipment and removed all the cartons that covered the fighter jet.

After doing this, Lin Yi looked up at the abandoned factory in front of her, then looked around and tested the surrounding wind speed.

After confirming that there was no problem, she nodded with satisfaction.

This area is very suitable for fighter jet test flights. In addition to being open and far away from other residential areas, it has a runway of sufficient length and the ground friction coefficient is within a reasonable range. In addition, there is a sea area in front. In case of an emergency during the flight, the fighter jet can directly crash into the sea to avoid causing too much damage.
