This so-called "academic exchange" did not last long.

Three days later, Vegapunk left.

When No. 2 asked about the results of this exchange, according to Vega Punk, it was a great success, and he also had a lot of new ideas. After returning home, he would be able to create an air weapon in at most a month.

Immediately, No. 2 passed the words of Vega Punk to the Five Old Stars.

Knowing such a result, the Five Old Stars are naturally very excited.

Moreover, Vegapunk also said that the people from the East China Sea Science Department did not have any secrets, and they took out all the technologies for communication.

This also surprised the Five Old Stars.

After all, they already had some doubts about Li Yan before.

But now that I look at it like this, it seems that I think too much?

If Li Yan really had any thoughts, he would never have taken out all the technologies like this without reservation.

Besides, Kaku is in the 18th branch, and so far there has been no report of any problems.

Twenty days later.

Naval Science Department.

These days, No. 2 has to come to the laboratory almost every day and report the progress to the Five Old Stars.

The prototype of this air weapon is also under the manipulation of Bergapunk, and the degree of completion is getting higher and higher.

It looks like it won't be long before it's done.

This also made the Five Old Stars very excited.

After all, in recent months, they had nothing to do with the air weapons of the revolutionary army.

And in the middle of the night...

Vegapunk in the laboratory is still busy.

At least...

On the surface it is.

But soon, Vega Punk, who was still busy, suddenly took out something and pressed it.

Immediately, a beam of overlord color, but with some different energy, ravaged most of the island in an instant.

Everyone, one counts as one, as long as they are awake, all of them lose consciousness and fall to the ground in an instant when their eyes go blank.

As for those who fell asleep, let alone, they didn't even have a chance to wake up.

All of this was naturally discovered by Number Two.

However, before he returned, who was patrolling the coast, a series of explosions occurred in the Science Department.

And when he returned to the Science Department, Vega Punk was long gone.

Even the prototype of the aerial weapon was also gone.

More importantly, a large number of design drawings that were originally stacked there have also been burned to ashes at this moment.

On the other side of the wall, there is a large hole that was blasted out.

After realizing the seriousness of the problem, No. 2 immediately contacted the naval headquarters more than ten kilometers away.

this night...

Almost all the navies in the headquarters, whether officers or soldiers, were dispatched. Centered on the island where the Ministry of Science was located, a large number of warships were surrounded by three layers and three layers, searching frantically.

However, this is doomed to be futile.

According to the various traces on the scene, No. 2 came to a preliminary conclusion.

Vega Punk and that prototype were hijacked!

A week later, the East China Sea.

A frigate is sailing on the sea.

Originally, this was nothing unusual.

After all, in the East China Sea, the Eighteen Branches often send **** fleets for patrol missions.

But at this moment, the people on this frigate are not simple.

"Li Yan, it's been a few days, should you tell me what's going on?"

"Don't worry, you'll know when someone arrives."

In the face of Zefa's question, Li Yan still smiled and sold his words.

"You brat is really... But speaking of it, there is something strange in the headquarters recently. I heard some students say that something big happened in the science department, so that all the warships in the entire headquarters were mobilized."

"It's really a big deal..."

"Huh? Do you know what happened?"

"Let's not talk about it, Mr. Zefa, the protagonist is here!"

"Who's here?"

There was a look of doubt, but soon, Zefa's sense of seeing and hearing also felt that it was indeed someone coming.

And it came from below.

"Underwater?"

"Yes, let's go, let's go meet him, after all, he is a big man!"

Although there are many questions I want to ask, but looking at Li Yan's appearance, I am afraid that he will not tell himself directly.

As a last resort, Zefa had to follow him to the side of the frigate.

After a few minutes...

A strange thing emerged from the water.

About seven or eight meters long, the whole body is black, and there are a pair of not long wings on both sides and the tail.

Maybe Zefa would think that this was more like a fighter jet, but Li Yan felt that it was very similar to a missile. After all, the wings of a plane would not be so short.

However, Li Yan is very clear that this is not a missile, and it was something he built after he gave someone some ideas last time.

Thinking of this, Li Yan also admired him.

In less than a month, it went from zero to something, and such a thing came out.

And this month, it even includes technical research, after all, I just talked about my ideas.

Soon, when the strange device was on, the hatch was opened.

Zefa was completely dumbfounded.

He knows this man...

It's all too familiar!

Isn't this Vega Punk?

Hell, how did Vega Punk appear here?

and many more...

There was a big incident in the Science Department, and even the headquarters dispatched all the warships.

Is it because...

hiss...

How did Li Yan do it?

Thinking of the connection of a series of things, Zefa also took a deep breath, and his eyes were full of shock.

"Dr. Vega Punk, welcome to join!"

"When can I get to the lab?"

Well, this guy looks like he can't wait~lightnovelpub.net~ Li Yan can't help but show a wry smile.

"Don't worry, I have prepared your laboratory, I guarantee you are satisfied!"

"Then what are you waiting for, let's go quickly. By the way, do you have anything to eat? There was some problem with the food calculation when we left, and it was consumed the day before yesterday..."

"Of course there is, come with me!"

Listening to the conversation between the two, Zefa was stunned.

after an hour.

After Begapunk finished eating, he was arranged by Li Yan to rest in a cabin.

"Li Yan, shouldn't you explain it to me?"

"Well, if this matter is to be talked about a month ago..."

at the same time.

Holy Land Mary Joa, Between Powers.

"It's been a week, and nothing has been found, not even who moved it!"

"According to No. 2, it was suspected that someone swept over half of the island with the overlord color that night, and within its coverage, even the two CP0 team members who were guarding outside the laboratory were in a coma. This level of overlord color, I'm afraid not many people can do it, right?"

"Indeed, the two CP0 team members have the strength of vice admirals, and it seems that only two people in this world can do that."

"That's right, even among the Four Emperors, there should only be white beards and red hairs, and it's possible to do it with all the power of the overlord."

"But the problem is, we have confirmed that the white beard is still not moving in his territory, and the red hair is..."

The Five Old Stars are constantly analyzing.

But this analysis has entered a dead end.

Whitebeard doesn't move, and redhead...
