It's past nine o'clock in the evening.

After Lin Yu explained the design ideas of the intermediate laser weapon, he left the nuclear test base.

He hadn't eaten for a day, so he had a big meal outside and replenished the energy needed by his body before returning to Su Muyun's house.

After a simple wash, Lin Yu fell asleep.

Nothing was said all night.

The next morning.

Lin Yu is compiling the last integrated cabin circulation technology.

However, before he could write much, Fu Xi's voice suddenly sounded.

"Mr. Lin."

As he spoke, Fu Xi's projection had already appeared on the table, looking at Lin Yu with a smile on his face.

"Huh?"

Lin Yu raised his eyebrows, stopped the movement in his hand, and asked with interest: "Fu Xi, why do you have time to come to me today, is it possible that the key technology of the second-generation mecha has been successfully developed?" ”

"Yes."

Fu Xi smiled and nodded.

"Hmm...... If this is the case, the successful development of the technology should be an inductive force field drive device, or a large-scale variable cycle engine control device, right? ”

Lin Yu thought about the timeline and said.

Fu Xi: "That's right, after half a year of research and development, these two key technologies have come out of the experimental type, if they can be successfully rolled off the assembly line, then the Xuannu Aerospace Fighter should not be far away." ”

"Okay, then I'll go and see how the results are, and you can inform Director Zhao."

Lin Yu got up, saved the comprehensive cabin circulation technology on the computer, and left Su Muyun's house.

Downstairs.

Jiang Feng was on standby in the car every day, always preparing for Lin Yu's trip.

Half an hour later.

Under the leadership of Jiang Feng, Lin Yu got on a special plane and came to the headquarters of the Academy of Sciences in Kyoto.

Today's Academy of Sciences can be said to be very busy.

Because they not only need to deal with the tasks assigned above, but also need to solve various key technologies written by Lin Yu.

Even, according to the instructions above, they have to give priority to solving the key technologies written by Lin Yu.

Therefore, the research team of every department of the Academy of Sciences is now happy and painful.

Happy, because they are developing cutting-edge technologies, which can leave a strong mark on their team.

And the pain is because there are too many key technologies, and they are too difficult, and the time and intensity of their daily work are doubled.

"Hahahaha, Lin Yu, it's the first time you've come to the headquarters of our Academy of Sciences today, it's been almost a year since the last time."

At the gate of the Academy of Sciences, Qiao Weimin walked over with a smile after seeing Lin Yu get out of the car, and said, "I said that I would have time to come to Kyoto to play, and by the way, look at me, an old man, but I didn't see the shadow of your kid." ”

Behind him, followed by Zhao Yu and a large number of greeting personnel.

"Dean Qiao said with a smile, I'm not busy developing second-generation mechas, if I had time, I would have brought Yun'er and them to see you."

Lin Yu smiled slightly, his tone quite helpless.

"Okay, I know you're busy, but today you have to accompany the old man and me to finish dinner before leaving, I haven't thanked you for the super architecture of the "Probe 4" calculation model you gave me last time, don't think about running this time. ”

"Otherwise, if my old friends knew, they would have to count the old man."

Speaking of the super architecture of the computing model, Qiao Weimin hurriedly grabbed Lin Yu's arm, as if he was afraid that he would escape, looking like an old child.

In this regard, Lin Yu couldn't cry or laugh, so he could only hurriedly agree.

Seeing that Lin Yu agreed, Old Man Qiao Weimin took him into the headquarters of the Academy of Sciences with satisfaction.

Along the way, the two talked about the research progress of the key technologies of the second-generation mecha, as well as the difficulties faced by the current key technologies.

During the conversation, the group came to the Department of Technical Sciences, one of the six departments of the Academy of Sciences.

The minister of technology and science here is an old man named Wei Minqiang.

He is also the head of inductive force field drive technology and large variable cycle engine control technology.

After Lin Yu greeted him,

The group took the elevator to an underground research institute.

This underground research institute has two areas.

The first area is dedicated to the study of inductive force field drives.

The second area is dedicated to the study of large variable-cycle engine controls.

Area 1 where everyone came first.

Spacious test site.

Lin Yu and others gathered around a large experimental platform.

At this time, what appeared in front of everyone's eyes was an oval-shaped black giant ring.

Its diameter, with the outermost ring made of metal, and the inner ring completely hollow, with only one layer of metal surface.

The upper part of it is erected on the experimental platform, and the lower part is connected to many thick cables.

On the whole, it looks like a hollow oval flatbread on a platform.

This is an experimental version of the force field drive.

At the same time, it was also the original appearance of the first version.

Now it doesn't even have a shell, and you can see the entire structure at a glance, as well as the stout cables outside.

Its basic principle is simple, it is to achieve contactless suspension and guidance between objects by electromagnetic force.

After that, the electromagnetic force generated by the linear motor is used to pull the object to run.

During this time, the outermost metal generates a magnetic force, which causes the object to be suspended in the air, canceling out the gravitational pull of the Earth.

Of course, it may be difficult to understand this, but it can be summed up in a sentence that ordinary people can understand.

That is the basic principle of magnetism and electricity, electricity and magnetism, same-sex repulsion, opposite-sex attraction, etc.

"Old Wei, have you done the test?"

Looking at the rudimentary force field drive device in front of him, Lin Yu asked.

"No, it's the first time."

Wei Minqiang shook his head and said, "However, we have tested the functions of each system separately, and after comparing the experimental data of each system, we have come to the conclusion that it can be run successfully. ”

"That's fine, as long as the experimental data is okay, it can basically be successful."

Lin Yu said confidently.

"In that case, let's start testing, it's too dangerous here, please go to the general control room to watch it remotely."

Qiao Weimin beckoned everyone to leave the test site.

Soon, Lin Yu and others came to the general control room.

The bell passed again.

After ensuring that all systems were operating normally, the engineers made an OK gesture to Lin Yu and others in the camera.

"Let's get started."

Lin Yu looked at the force field drive device below with a calm expression.

The voice fell.

The power supply of the force field drive device in the No. 1 experimental field was switched on instantly.

In an instant, a powerful electric current surged wildly on the outermost metal ring.

As the arc flickered, a terrifying magnetic field slowly formed inside the metal ring.

Meanwhile.

The metal surface of the hollow inner ring began to glow faintly.

This is because the electrons on the outermost metal ring begin to move due to the change in the magnetic field, forming a loop, so that the magnetic field of its own is also generated.

These two large magnetic fields, guided by a huge current, form a huge repulsive force that begins to act on the hollow inner ring.

For a while, the originally hollow inner circle began to emit a hazy white light.

This white light is a photochemical phenomenon in which spilled electrons run out of atoms or molecules.

If someone can look at the white light of this inner circle up close, they can clearly see that countless dust and fine debris are suspended in the air, one after another.

Obviously, this is the result of a successful run.
