Villain: The system is activated, let the heroine go at the beginning

Kui cow alloy?
Lei Zi followed behind the two, muttering to himself.

And Qin Huanyu also seemed a little puzzled.

"Kui Niu Alloy?"

Like Pangu Technology, which didn't exist in the original plot at all, it was created by himself.

So it doesn't show up in the plot.

And he had never heard of the alloy that Shuang'er and the others made.

Even, it can't be found in the system mall.

The three walked forward together.

Shuang'er also quickly explained.

"Master, you don't need to worry about this name."

"Kui Niu is just a kind of mythical beast in Shan Hai Jing, but we named it as an alloy."

While speaking, several people had already walked to the test bed.

Everyone saw them coming.

First he saluted Shuang'er, and then he noticed Qin Huanyu.

Several of them met Qin Huanyu when they were experimenting with mantra potions.

Thinking back in my mind at this moment, I couldn't help but feel a little scared on my expression.

"Master Qin Qin!"

Those who didn't know Qin Huanyu knew about it through other people's introduction.

Everyone saluted Qin Huanyu again.

Qin Huanyu waved his hand, indicating that they don't need to be polite.

His eyes focused on the test bench not far away.

There was also a gray cloth covering there, blocking something below.

About ten meters high and more than 30 meters wide.

It's just like.
Just like when Xia Guo released the H20, it was hidden under the curtain.

Qin Huanyu narrowed his eyes and raised the corners of his mouth slightly.

He seemed to have guessed what Shuang'er was doing.

At this time, Shuang'er came out again.

He ordered several people to move over some iron frames.

At the same time, he looked at Qin Huanyu: "Master, come and have a look, this is the Kui Niu alloy we made."

Qin Huanyu turned his head and looked in the direction Shuang'er pointed.

At the same time, Lei Zi also looked around curiously.

I saw several metal plates one meter square were fixed on the iron frames.

It looks like a silver-gray metallic luster.

But looking more carefully, there is actually a little blue-yellow brilliance hidden in the silver-gray.

There are three alloy plates in total, each with a different luster.

The thickness is only about a millimeter or so.

Shuang'er summoned two people and asked them to bring protective clothing to Qin Huanyu and Lei Zi.

But both of them held out their hands and refused.

Seeing this, Shuang'er didn't force it.

Putting on the protective clothing by himself, only a small head was exposed.

He opened his mouth and introduced: "Master, among the technologies you gave, there are many technologies related to materials science."

"This Kui Niu alloy is made by us through analyzing technology and according to the existing element ratio."

"According to the level of civilization, this Kui Niu alloy should belong to between the first and second level civilizations."

Shuang'er said, and at the same time asked someone to bring some weapons.

At the same time, under the control of Asking.

The area around the test bench was cleared, leaving only a dozen or so figures standing here.

"Thunder."

Shuang'er shouted and pointed to the small table.

On the table, there were many firearms, and there was even an individual RPG.

"Choose something casually and test the strength of the alloy."

Lei Zi glanced at Qin Huanyu.

After getting his approval, he stepped forward.

After a glance, he picked up one of the M82A1 sniper rifles with one hand.

It also has a more impressive name - Barrett!

"All the firearms tested today are equipped with special armor-piercing bullets, which can penetrate 500mm steel plates and kill enemies at least within a distance of 5 meters."

Following Lei Zi's movements, Shuang'er also introduced.

"Today, all firearms are tested at their maximum lethal range."

Fourteen kilograms of Barrett, Lei Zi lifted it up with one hand.

Everyone also backed away.

Only Qin Huanyu was still standing there.

Because Shuang'er was wearing protective clothing, she also stood beside him and explained.

Reach out to signal Lei Zi, he can start at any time.

Lei Zi nodded.

Load, pull the bolt, aim!
boom!
He didn't hesitate too much, and directly fired a shot at Alloy.

After a loud bang.

The bullet precisely hit the Kui Niu alloy.

And because the underground base was too big, even the echo didn't sound.

The gunpowder dissipated.

Soon someone stepped forward to move the hit alloy in front of everyone.

Qin Huanyu's gaze also looked at the hit piece of alloy.

His eyes instantly focused on the alloy plate.

Lei Zi's shot just now must have hit the alloy plate.

But at this time, the alloy plate placed in front of everyone was not damaged at all.

Not even a scratch was found.

soon.

Someone else found the warhead.

When I brought it over and put it on the table, the special armor-piercing projectile of more than ten centimeters had already turned into a discus.

It was the size of a palm, and the entire projectile had been distorted.

Seeing this scene, Lei Zi suddenly widened his eyes.

He dropped the rifle straight away.

At the same time, he reached out and took the alloy plate on the table.

It wasn't until I got it in my hand that I realized how thin this alloy plate was.

Probably not even a millimeter thick.

It is about the thickness of a dozen sheets of paper.

Moreover, Lei Zi made an even more shocking discovery.

He weighed it carefully twice.

He raised his head in astonishment: "Master, this alloy plate is so light."

At this moment, Shuang'er, who was standing aside, showed a proud smile again.

He took the alloy plate from Lei Zi's hand and handed it to Qin Huanyu.

"Master, this is Kui Niu Alloy!"

"It's ten times thinner than a high-strength steel plate, but its protective ability is even stronger!"

"Moreover, its density is fifteen times lower than that of titanium alloy!"

hiss--

Qin Huanyu squinted at the alloy plate in Shuang'er's hand.

He also stretched out his hand and took the metal plate into his hand.

Although mentally prepared.

But when he got it in his hand, he was still shocked by the quality of the alloy plate.

Thermal knowledge: The density of titanium alloy is generally about 4.51g/cm3.

and one-fifteenth of it
That is 0.3g per cubic centimeter? ?
As we all know, the density of water is 1g per cubic centimeter.

The density of your alloy plate is not even one third of that of water?

If you use it to build a boat, don't you need to consider the displacement of the hull, and you can float by yourself?
If it's just these, it's not enough to make Qin Huanyu's heart flutter.

He raised his head lightly and looked at something hidden under the gray cloth not far away.

It seems that even if the sixth-generation test machine pulls his hips in this military exercise, he can save himself.

"Not bad." Qin Huanyu praised.

Reaching out to rub Shuang'er's head, a smile appeared on his face.

"What surprises are there for me, should you take them out now?"

The few remaining Kui Niu alloy plates were originally planned to do several more tests.

But Qin Huanyu's words, coupled with his actions just now.

The bigger surprise had obviously been guessed.

Shuang'er pursed her lips and snorted lightly.

Then he smiled.

"Master, you can't let others show off."

As he spoke, he nodded to the few people behind him, and at the same time asked people to remove all the experimental things.

Reaching out his hand towards Qin Huanyu, he pointed at the huge monster beside them.

"Master, the things here are a big gift prepared for you."

With Shuang'er nodding slightly.

Someone pressed the button and put the gray cloth down.

The things under the curtain finally appeared before their eyes.

The expressions of Qin Huanyu and Lei Zi's eyes widened at the same time, and their mouths opened slightly.

The two of them froze there at the same time!
