The waiting process was boring, so Lin Fang simply slipped into the helicopter and sat down.

Even if the seat is not very comfortable, it is better than standing.

Zhang Ruohan called for too long, so Lin Fang simply returned to the original earth again.

As soon as he came in, he felt a trace of vague connection from Qin Long.

Lin Fang appeared near Qinlong and immediately received a message from it that he was eager for the soul sand.

Because of the fusion of the soul sand grain and the old th10 engine in the Qinlong belly cabin, if it wants to improve its performance and continue to upgrade, it can only swallow more soul sand grains.

But in the entire original earth, Lin Fang only has something.

So as soon as he came in, Qin Long was like a real little animal, sending information to Lin for food.

This made Lin Fang a little amused.

This g20 is simply a sting. No wonder it tells Lin Fang that the engine is insufficient and needs to be upgraded. It also transmits three upgrade plans in a row.

But in the end, Lin Fanggu showed a Qinling Type 1 engine that was planned to be replaced by Qin Long, but it refused.

Lin Fang didn't think much about it at that time, and he only came back to the taste.

This little thing has been planned for a long time!

Lin Fang hovered in the air, touched Qin Long's nose, comforted it and said, "Don't worry, I'll bring you food next time. Besides the engine, where else do you need to upgrade?"

No matter how smart Qin Long is, he can't get out of Lin Fang's palm. He is just a tool guy... a tool machine until he is old!

Buzz!

Several messages came, and Lin Fang received several structural diagrams.

This time, from the aerodynamic layout to the appearance of the aircraft, Qin Long made a major change.

As Lin Fang thought about it, new composite parts appeared in front of him, and then according to the structure of the drawings, they were spliced ​​and combined by themselves, suspended in front of him, and became three brand new fighter jets.

The whole aircraft is completely black and the overall style is streamlined. Even if it is a duck-like layout, it is completely different from the previous G20. It is hard for anyone to believe that this is an upgraded fighter jet derived from the G20.

The second plane was bright red all over, and it was as good as it was, and the first black plane had a little bit of a g20. This red plane was like an alien fighter flying out of a science fiction film, which was so dazzling.

The third aircraft is matte and black, inconspicuous, and not outstanding in appearance. It looks ordinary and looks at it at first glance, without any characteristics, giving people the feeling of "this is just a fighter".

Because Qin Long is a useless man who has no name, Lin Fang naturally named the three new fighter jets separately.

The first black fighter was named Lilong Type 1, which is a standard fifth-generation fighter, infrared stealth and supersonic. Compared with the g20, in addition to the aerodynamic layout and streamlined improvement, it also uses a brand new coating material, which is almost completely stealthy against radar.

The second red fighter jet is named Red Dragon 1. This is already a sixth-generation fighter jet that is only in the concept. It is controlled by artificial intelligence, air-aberatically, land, sea, air, sky, electricity and network integration, and has fully realized the interconnection and interoperability based on the Internet of Things.

The third inconspicuous matte black fighter jet was named Yinglong Type 1 by Lin Fang. This aircraft is a real space fighter jet, with near-ground cruise, high-energy lift-off to fight satellites, and low-energy punches at dawn.

Lin Fang figured out the various performances of the three aircraft and was about to express his excitement, but when he was on the test flight, he cursed directly.

In addition to the Lilong Type 1 that can be used immediately, the Red Dragon Type 1 and Yinglong Type 1 have their own problems.

One is to solve the material problem and the other is to solve the weapon problem.

Of course, hypersonic fighters must be equipped with hypersonic missiles, and they cannot continue to use supersonic missiles.

When you rise into space and return, friction with the atmosphere is a big problem. The materials you use must consider higher strength, more corrosion-resistant and lighter.

All of these require Lin Fang to devote himself to researching them, and Qin Long only provides direction.

After all, it is just a juvenile machine, unless... Lin Fang invests a lot of soul sand to upgrade it, he may be able to realize the recipe of these things.

Lin Fang figured out this and couldn't help knocking on Qin Long's nose.

Nowadays, even fighter jets have their souls and are starting to become deteriorated!

Lin Fang comforted Qin Long for a moment and left the original earth.

He wondered if he really didn't let go, could he consider building a plane himself?

Anyway, the materials are not expensive, just bring them directly from the original earth.

You can also assemble it directly and bring a whole machine here, that is...

Lin Fang thought about it and decided to give up the idea of ​​committing suicide.

I brought the parts to assemble them myself, and at least I could say that I had developed it myself.

It is hard not to think too much about a whole machine if you just put it out.

Lin Fang was secretly alert and he would have to be more cautious when bringing things out of the original earth in the future.

Even if Zhang Ruohan asks about it for a while, he will have to make a Qinling Type 1 engine, which is already very difficult and requires a rest for several weeks.

In the future, try to get the parts or drawings out to avoid trouble.

"Dr. Lin!"

"Can you open it?"

"No, Dr. Lin, I applied to the above. The above proposed a plan, which is that you have to pass the virtual flight assessment and reach the corresponding level before you can get on the plane! If you don't agree, then sorry..."

"I agree, let's go!"

Zhang Ruohan rubbed his eyebrows in distress, and could only helplessly stop Lin Fang who had walked a few steps, and said, "Dr. Lin, wait a moment, I'll call a car. We are still a bit far from the training center."

After a while, a military green off-road vehicle drove over, and the two got into the car and headed straight to the training center.

When they arrived at the training center, a middle-aged officer with frown on his face was already waiting by the door.

Seeing Lin Fang, the middle-aged officer frowned unconsciously, making his frown even tighter.

"Col. Shang, this is Dr. Lin Fanglin who I mentioned to you on the phone. He is your student today. Dr. Lin, this Colonel Shang Yongfei Shang is your instructor today. I think it is better for you to do some training and then evaluate..."

"No."

Lin Fang shook his head and said, "Let's take the exam directly, I can do it."

"Dr. Lin, do you really don't think about it anymore? There is only one opportunity. Once you fail, you can only take C919 to the Chinese Academy of Sciences with me!"

"No, come on."

Zhang Ruohan covered his forehead, sighed secretly, and said to Shang Yongfei: "Col. Shang, then start directly!"

Shang Yongfei looked at Lin Fang in surprise, and his impression of him was a little better. His frown brows relaxed a little. He nodded slightly and said, "Okay, then let's start."

The group of three came to the simulator and saw that there was nothing surprising about the appearance. Lin Fang changed into his flight suit and was surprised after he sat in.

The dashboard, joystick, and even every button are exactly the same as the g20 he has fallen countless times.

This simulator has really achieved one-to-one details, but I don’t know how the flight is.

“Are you ready?”

“It’s ready.”

Lin Fang felt that he had nothing to prepare. He was in good health and could fly even if he didn't wear a flying suit.

"start!"

With Shang Yongfei's order, the three screens in front of Lin Fang lit up together, and what they showed was the appearance of the runway.

Lin Fang controlled the plane and took off slowly.

In the helmet, Shang Yongfei's cold voice soon came: "Dr. Lin, your goal in this assessment is to successfully escape and land safely at the designated location surrounded by four enemy planes."

Lin Fang: "???"

After a moment of surprise, Lin Fang couldn't help but say, "No! What's the situation? Didn't you agree to test your flight technology? Why are there any enemy planes?"

Shang Yongfei said lightly: "The assessment that best tests flight technology is practical combat. Although the enemy planes are fake, your opponent is real. They are all real pilots who are controlling it. Dr. Lin, remember not to take it lightly, and I wish you good luck."

God wishes me good luck!

Stop me and don’t leave after school!

Lin Fang thought that Zhang Ruohan would not let herself pass the assessment easily, but she never thought that she could be so shameless that she could directly increase the difficulty to this level.

"Faced with the escape of four enemy planes, why don't you let me explode the enemy planes in turn?"

"In view of Dr. Lin's new request, the assessment target has been changed to: shoot down four enemy planes!"

I don't, it's not me, you're talking nonsense!

I was asking back, don't you understand?

Lin Fang had no time to argue with Shang Yongfei. When the plane took off, he checked the ammunition reserves as soon as possible.

Seeing the huge "6" prompted by the computer, Lin Fang couldn't help but want to scold people even more.

4 pieces pl15, 2 pieces pl10.

With an average of 1.5 missiles, it is necessary to shoot down an enemy plane. Does Shang Yongfei treat himself as a foolproof super ace?

No matter whether it is, Lin Fang can only think that he is now.

After Lin Fang drove the plane into the air, he quickly came to a large circumference, intending to touch the surrounding environment first.

Although Shang Yongfei was not a human being, he was not shameless. He did not let four enemy planes ambush around him from the beginning, and directly gave Lin Fang a circumambulation, but gave him a few minutes of preparation time.

Basically, just one week after Lin Fang drove the plane around the air combat area, Shang Yongfei's voice came from the headset: "The test time is over, and the assessment has officially begun!"
