The scientific community went crazy when a mecha was given to a granddaughter at her birthday party

The student was very happy, but the teacher was very happy.

Mr. Zhan handed the student ID back to Xu Fan.

He looked at Wang Yixue,

"Yixue, you are an honest child!"

"Tell me, is what Xu Fan said true?"

Mr. Zhan and the researchers all looked at Wang Yixue.

In this situation, Wang Yixue should not lie, right?

Commander Zhang said with a straight face,

"Yixue, tell the truth!"

Wang Yixue nodded.

Then he looked up at Mr. Zhan and said solemnly,

"Mr. Zhan, I can prove that what Xu Fan said is true!"

"I don't believe it!"

Mr. Zhan almost jumped up when he heard this.

"One person developed such a big thing in less than 7 days!"

"Power system, central control system, weapon system, casting of various components, and the magical coating..."

Speaking of this.

Mr. Zhan suddenly paused.

Regardless of his image, he grabbed Xu Fan's arm.

Approaching the Deep Sea Titan.

Pointing at the black metal on the outer layer of the cockpit.

Squinting his eyes, he asked,

"Since you developed it all, then this..."

"You must want to ask about this black nano invisible coating, right?"

Xu Fan cast a discerning look at Mr. Zhan.

He introduced with great excitement,

"This material is a new type of metal coating that I have recently developed."

"It has unique physical properties and has excellent stealth effect on radar detection."

"In addition, when it comes into contact with carbon yne alloy, it will naturally form a strong honeycomb structure."

"It effectively reduces the radar reflection cross section."

"Finally, the entire Deep Sea Titan has achieved complete radar stealth."

"I said this, you should understand?"

Mr. Zhan's face froze.

His eyelids twitched slightly.

"This..."

For a moment, he didn't know what to say.

Is it too embarrassing to say that he didn't understand?

The problem is that he really didn't understand!

What is the unique physical property?

And what material is that carbon yne alloy?

Mr. Zhan thought that his knowledge was broad enough.

I didn't expect that he would be stumped by a little kid today.

He couldn't help but blush.

Director Chen and the researchers beside him were also confused.

What the hell is this talking about?

Is it really because their knowledge is too narrow that they can't understand it?

Mr. Zhan paused for a moment.

He was breathing heavily with a huff and puff.

He pointed to the core engine of the Deep Sea Titan.

"Xiao Xu, what's the matter with this engine?"

Xu Fan looked at the hydrogen-powered engine.

His eyes showed an unconcealable fondness.

"You mean that!"

"The hydrogen-powered engine."

"Unlike ordinary hydrogen fuel engines, the hydrogen fuel here is stored in a high-pressure liquid state and works in a gaseous combustion mode."

"The mechanical energy converted by combustion accounts for less than 5% of the loss."

"Intake, compression, work, and exhaust have all reached a nearly perfect state."

"This is the real essence of this deep-sea Titan."

"When running in humpback whale mode, it can burst out an amazing power of 300,000 horsepower in 0.01 seconds!"

"And there are small combustion chambers scattered around the collective, and you must know about them."

"I don't need to say it, right?"

Mr. Zhan's old face trembled twice again.

Because of so many people, he didn't speak directly.

He asked Director Chen beside him,

"Director Chen, you should understand it too, right?"

"I... I'm okay!"

Director Chen's face was a little stiff.

Mr. Zhan turned his head and looked at the researchers around him.

"Do you guys understand?"

Several people looked at each other for a few seconds and finally said.

"It's OK!"

"How can it be OK!"

Mr. Zhan's eyes lit up, pretending to blow his beard and glare, and coldly taught him a lesson.

Then he looked at Xu Fan and smiled kindly,

"Xiao Xu, why don't you explain it to those who don't understand?"

Xu Fan nodded,

Continued what he said before,

"The small combustion chamber uses the excess fuel in the main combustion chamber."

"Its function is to form a gas bionic form around the deep-sea Titan."

"That is to say..."

Xu Fan said a lot of things like pouring beans.

A group of people took notes in their notebooks.

Mr. Zhan was completely in the state.

At this moment, he seemed to have become a primary school student.

When Xu Fan talked about the key points, someone asked a question.

After understanding, the whole person was as happy as a child.

After more than 20 minutes, he finally finished.

Wang Yixue handed Xu Fan a bottle of water as usual.

Xu Fan took two gulps.

"Mr. Zhan, do you have any questions?"

No one spoke.

Except for Mr. Zhan, the researchers around him were all confused.

I wrote dozens of notes and now look back.

I can't say I don't understand.

I can only say I don't know what I wrote.

Commander Zhang doesn't know much about scientific research.

But seeing Xu Fan's ease in answering.

He said again,

"So, you are the one who took charge of the research and development and manufacturing of this Deep Sea Titan?"

"Of course!"

Xu Fan nodded vigorously.

After a slight pause, he explained,

"You don't know, I just came down from the mecha production line..."

"Stop... Stop! What mecha production line?"

Commander Zhang suddenly interrupted.

Xu Fan covered his mouth fiercely.

Damn, I let it slip!

The mecha is still a hidden project and cannot be made public.

"Ahahaha... there is no mecha..."

"Ahem..."

"I mean, I just finished my work and the leader's instructions came down."

"It said that we should build a deep-sea submersible that can dive to 10,000 meters under the sea."

"It requires a strong engine, a large body, and mining tools."

"Think about it, the leader has spoken, how can I not work hard."

"I worked day and night, and finally got it done in 5 days."

"You may not believe it, I lost a pound!"

After saying that.

Xu Fan also symbolically showed his arms.

When Wang Yixue heard Xu Fan say that he had lost weight, he silently cast a distressed look.

After talking for a while.

Commander Zhang was even more confused.

Before, Wang Yixue said that it was made in five days.

Now Xu Fan also said so!

Zhan Lao, who was standing by, had already believed it a little.

Xu Fan knew the entire Deep Sea Titan like the back of his hand.

He even knew how many rivets were used in which place.

At this time, Xu Fan suddenly thought of the backpack he was carrying.

He hurriedly took it off.

"I almost forgot that I also have these drawings. I brought them all to you!"

Xu Fan took out all the drawings in his backpack and handed them to Zhan Lao.

He also handed over two USB flash drives with large storage capacity.

In this way, if there is a small problem with Deep Sea Titan,

they can solve it themselves, and he doesn't have to run around.

It can save a lot of trouble.

The moment Zhan Lao took the drawings, he saw the content on it.

He took a breath of cold air.

His pupils also shrank into small black dots.

"This... is this the drawing of Deep Sea Titan?"

His voice was trembling, full of excitement and excitement.
