I thought I was still Long Aotian

The place Yuen Long went to was very desolate. After getting off the plane, he saw a desert. The soldier who came to pick up the plane handed over a pair of black blindfolds. He apologized: "Comrade, this is a regulation, please cooperate."

Yuen Long readily agreed.

Seeing the light again, it was his younger uncle Yuan Qingsong who personally lifted the blindfold for him. His appearance is seven points like his grandfather's. He is dressed in a capable training uniform, with a spike and a flower on his shoulder. It seems that his military position is not small.

"Why, you don't recognize me?" Yuan Qingsong raised his hand and licked Yuen Long's head like he was treating a child.

Yuen Long lowered his head slightly to let him touch him, apologizing for the old lady and his aunt, "Uncle, you haven't been home for several years! Grandma said that if you don't come home this Spring Festival, she will hardly remember what you look like, little Although my aunt didn't say anything, she asked me to bring a box of postcards. However, all the personal items I brought were confiscated, and she said that I could only get them back when I left."

Yuan Qingsong paused, let go of Yuen Long, Wei Wucha sighed, and then said hopefully: "If you can decipher that layer of paint, maybe this time I can go home with you for a vacation."

Yuen Long: "What paint?"

Yuen Long was very curious, and because of the so-called paint, he was brought to this mysterious underground military base.

Yuan Qingsong: "It is an invisible coating developed by country A. Our experts analyzed that the coating contains nickel-zinc ferrite, manganese-zinc ferrite, etc., but the coating we produced cannot completely absorb electromagnetic waves. I think you are Graduated from MIIT in country A, and majored in materials science, I heard that I also worked for the National Academy of Sciences for a while, so I thought maybe you could analyze the reasons for us.”

Yuen Long: Investigate his affairs clearly!

Did his uncle know that he had researched the graphene solution in private, so he brought him here?

However, he was also a little curious, what did the invisible paint on the ancient earth look like?

In addition to the bionic composite fiber layer, the invisibility suit of the Empire era also uses the four-dimensional space transition to become invisible, so he invented the space cannon with biometric recognition, which can automatically lock the target in different spaces.

Yuen Long followed Yuan Qingsong enthusiastically to see the so-called invisible paint.

After going through several turnstiles and security checks, the first thing he saw was the gun and shield research and development laboratory. This laboratory is surrounded by bulletproof steel reinforcements. From the transparent bulletproof glass window in the middle, you can see the huge equipment and full of room dust.

The uncle introduced: "The dust experiment is being done here to test the accuracy of the gun in the sand and dust environment."

Yuen Long nodded. Most of the guns on the ancient earth were mechanical structures, and the combat environment was limited to the earth. The impact of the environment on guns is a relatively important issue.

Yuen Long doesn't want to do military work anymore. In his last life, he was assassinated by the enemy because he developed a space cannon. In this life, he just wants to live an ordinary life and experience family affection.

Uncle took him to continue walking, passed the electronic equipment laboratory, and came to the special materials laboratory.

As soon as he entered the door, he saw several veteran scientists looking towards him, including Academician Liu of the National Academy of Sciences.

Yuen Long went over to say hello to them, especially this Academician Liu, they had studied the bionic skin of robots together, so they were old acquaintances.

Academician Liu grabbed Yuan Long's hand excitedly: "Xiao Yuan is here, come and take a look at this."

It was a piece of black iron, only the size of a palm, with cutting marks around it, irregular, as if it had been cut from something hastily.

It was very strange, but Yuen Long didn't ask too much. Everything here is kept secret, and it is estimated that no one would tell him if he asked.

Yuen Long wanted to reach out to pick it up and observe it carefully, but academician Liu grabbed his wrist, and he handed over a pair of gloves: "Put it on, and reduce friction. This is all there is to this thing, it can't stand a little wear and tear!"

Yuen Long said in his heart that it was impossible, he could wipe off two micrograms of paint by touching it!

However, he knows how to do as the Romans do, so he took the gloves and put them on to give everyone peace of mind.

Under the gaze of everyone, Yuen Long picked up the piece of metal and looked at it.

He asked casually: "This is a piece of aluminum alloy skin, is it used on an airplane?" He gently folded the metal corner, and said: "The flying altitude is probably above 2 meters. In ancient... Cough, it should be a fighter jet that reaches this height on the earth. Is this a piece of skin on the stealth fighter jet of country A?"

No one told him the origin of this piece of metal, but he guessed so accurately that everyone was shocked.

So much information can be analyzed by touching a piece of material, which shows that Yuen Long is familiar with this piece of metal.

The old scientists who had been taught about Yuen Long's background and achievements by Academician Liu couldn't wait to ask about this metal coating.

Yuen Long shook his head: "What is it, I have to use tools to test it."

Academician Liu: "Okay, I have everything over there, and the list of ingredients I analyzed before, come with me."

Yuan Long followed Academician Liu to his dedicated laboratory, leaving a group of old scientists all gathered around Yuan Qingsong.

This one said: "Major General Yuan, in addition to materials science, has your nephew also made great achievements in electromechanical equipment?"

That one said, "That's right, I also heard from Academician Liu that your nephew is very good at computers."

Another said: "He is really an all-around talent, the most suitable for our work here, shall we keep him?"

Yuan Qingsong: ...

To be honest, he also thought about this idea, but he couldn't pass the test of his old man and his wife.

His son Yuan Yu was sent into the army as soon as he was an adult, and he left home for eight years. Now he is carrying out secret missions somewhere and has never returned home.Yuen Long was very rebellious when he was young. He was sent abroad to study by his brother. It took about nine years and he just came back.

Not to mention the old man, the other two ladies in the family probably wouldn't agree either.Especially his wife, who couldn't get in touch with her own son, could only transfer her love for her son to Yuen Long. He and his son were not at home all year round, and she relied on making overseas phone calls to Yuen Long for comfort.

When talking on the phone with his wife not long ago, she was full of words about Yuen Long. If he got Yuen Long to work in this closed base again, his wife would probably divorce him if he was not crazy.

So, at the moment, I can only politely refuse.

Several scientists are people who love talents, and they are quite disappointed after hearing this.

After reading the analysis data of Academician Liu, Yuen Long began to prepare the experimental equipment he needed, and explained to Academician Liu at the same time: "If it is a stealth aircraft, its shape design must avoid using large areas and vertical planes. Generally, a curved or concave surface is used, which can deflect the scattered signal and make it difficult to be detected by radar."

"Secondly, stealth aircraft use non-metallic materials or radar absorbing materials. During this period...non-metallic materials are mostly made of carbon fiber composite materials, while radar absorbing materials are magnetically filled with ferrite..."

During his time at the National Academy of Sciences, Yuen Long has used his rich knowledge to prove the correctness of the theory time and time again.

Dean Liu said bluntly: "The cost of carbon fiber composite materials is too expensive. Is the ferrite magnetic filling nickel-zinc oxide and manganese-zinc ferrite?"

Yuen Long: "It's possible. With today's technology, barium ferrite can also be made. After I finish testing this paint, let's analyze it in detail."

Dean Liu: "Okay."

He found a chair, sat down next to him, and didn't bother Yuen Long anymore.

Three people must have my teacher. These veterans who love science are broad-minded and do not look down on Yuen Long. They have dedicated their lives to the cause of science with the spirit of living to learn and learning.
