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 Vegapunk, it was a great success. He also had a lot of new ideas. After returning home, he would be able to build an aerial weapon within a month at most.

Immediately, Number 2 passed Vegapunk's words to Five Old Stars.

Knowing such a result, Wu Laoxing was naturally very excited.

Moreover, Vegapunk also said that the people from the Donghai Science Department did not hide any secrets and brought out all their technologies for exchange.

This also surprised Wulaoxing.

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

But looking at it now, it seems that I am overthinking it?

If Li Yan really had any intentions, he would never be able to show off all his skills without reservation like this.

Besides, Kaku is in the Eighteenth Branch, and so far there has indeed been no report of any problems.

------

More than twenty days later.

Department of Naval Science.

These days, No. 2 comes to the laboratory almost every day to check on it and report the progress to Wulaoxing.

The prototype of this aerial weapon is also becoming more and more complete under the control of Vegapunk.

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

This also made Wulaoxing very excited.

After all, in recent months, they have been unable to do anything with the revolutionary army's air weapons.

And just in the middle of the night...

Vegapunk in the laboratory is still busy.

At least...

That's so on the surface.

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

Immediately, a wave of energy that looked like an overlord but had some different energy ravaged most of the island in an instant.

Everyone, every one of them, as long as they were awake, lost consciousness and fell to the ground as soon as their eyes turned white.

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

All this was naturally discovered by No. 2.

However, before he could return from patrolling the coast, a series of explosions occurred within the Ministry of Science.

And when he returned to the Science Ministry, Vegapunk had long disappeared.

Even the prototype of the aerial weapon has also disappeared.

More importantly, the large number of design drawings that were originally piled there were now burned to ashes.

On the wall on the other side, there was 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 navy in the headquarters, whether officers or soldiers, were dispatched. With the island where the Science Department is located as the center, a large number of warships surrounded the island three floors inside and three outside, searching frantically.

However, this is destined to be in vain.

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

Vegapunk and the prototype were hijacked!

------

A week later, Donghai.

A frigate is sailing on the sea.

Originally, this was nothing unusual.

After all, in the East China Sea, the Eighteenth Branch often sends escort fleets to conduct patrol missions.

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

"Li Yan, it's been several days, it's time to tell me what happened, right?"

"Don't worry, you'll know when people arrive."

Facing Zefa's question, Li Yan still smiled and pretended.

"You're such a kid... But speaking of which, there has been something strange in the headquarters recently. I heard some students say that something big happened in the Science Department, so much so that all the warships in the entire headquarters were mobilized."

"Something really happened..."

"Huh? Do you mean you know what happened?"

"Let's not talk about it for now, Teacher Zefa, the protagonist is here!"

"Who's coming?"

There was a look of confusion on his face, but soon, Zefa also sensed that someone was indeed coming.

And it comes from below.

"Underwater?"

"Yes, let's go and greet him. After all, he is a big shot!"

Although he had many questions to ask, looking at Li Yan's appearance, he was afraid that he would not tell him directly.

As a last resort, Zefa had no choice but to follow him and walk to the side of the frigate.

A few minutes later...

A strange thing emerged from the water.

It is about seven or eight meters long, completely black, with a pair of short wings on both sides and tail.

Zefa might think that it looks more like a fighter plane, but Li Yan feels that it looks like a missile. After all, the wings of the plane are not that short.

However, Li Yan knew very well that this was not a missile, and it was something he created after he gave someone some ideas last time.

Thinking of this, Li Yan admired him very much.

In less than a month, something like this was built from scratch.

And within this month, it even included 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 is familiar with this person...

It's so familiar!

Isn't this Vegapunk?

Damn it, why did Vegapunk appear here?

etc...

Something big happened at the Ministry of Science, so much so that all the warships were transferred there.

Is it because...

hiss...

How did this kid Li Yan do it?

Thinking of the connection between a series of events, Zefa also took a deep breath, his eyes filled with shock.

"Dr. Vegapunk, welcome to join us!"

"When can I get to the lab?"

Well, this guy seemed to be impatient, and Li Yan couldn't help but reveal a wry smile.

"Don't worry, I've prepared your laboratory, I'm sure you'll be satisfied!"

"Then what are you waiting for? Let's go quickly. By the way, is there anything to eat? There was something wrong with the food calculation when we left. It was all used up the day before yesterday..."

"Of course there is, come with me!"

Listening to the conversation between the two, Zefa looked confused.

After one hour.

When Vegapunk finished his big meal and was arranged by Li Yan to go to a cabin to rest.
