My granddaughter gave me a mecha for her birthday, and the scientific community went crazy

The shell hit Xu Fan hard in the chest in an instant!

Time seems to have slowed down at this moment!

The warhead filled with high explosives cracked inch by inch, and extreme white light flashed violently from the cracks.

The warhead fragments fired violently in all directions!

"boom--"

Xu Fan is covered in blue smoke!

A strong explosion made the ground shake.

Long Guang's violent heartbeat almost jumped out of his throat!

Staring at the figure covered in smoke and dust in the distance.

The two old palms pinched each other tightly.

Wei Dongren next to him subconsciously took half a step forward, wanting to go up and rescue people.

But he understood that if he was hit head-on by a rocket at such a close range, his whole body would be torn apart. How could he save him? !

Dead! !

Mr. Zhan's breathing stopped, and his face was as pale as the students.

Many timid girls hid behind others and huddled up.

Afraid of seeing the bloody and bloody scenes.

They were all frightened.

I have never seen this method of testing equipment!

In order to test the effect of combat more intuitively, blow yourself up with rockets! !

In this world, I am afraid that only Senior Xu Fan can do this!

Some people have said before that Senior Xu Fan is a madman in scientific research. He will risk his life to conduct scientific research and test in order for Xia State to no longer be bullied by the big powers!

Now it seems that this is absolutely true!

Sacrifice!

Some students' eyes were filled with tears, and their hearts were as shocked as a surging river. Their outlook on life was rewritten because of this!

Countless people were nervous and frozen in place.

He stared blankly at the smoke that gradually dissipated.

There was a dead silence all around.

Needle drop is audible.

This time!

"Old Xu! Do you want another shot?"

Not far away, Li Guozhong suddenly shouted.

Countless eyes suddenly fell on Li Guozhong.

Especially Long Guang's eyes were simply killing people.

Li Guozhong instantly had the illusion that he was being targeted by a wild beast and shuddered.

"No need, Lao Li, the test results are pretty good!"

A sunny voice sounded, and Xu Fan stepped out of the smoke.

A dense layer of shrapnel was absorbed on the tactical vest.

He himself is intact! In other words, there is a little black ash on the chin!

Long Guang's eyes fell on Xu Fan and his eyeballs trembled violently.

What kind of body is this? Even a rocket launcher can't damage it!

Is it the Extremis virus or... the tactical vest?

Seeing the layer of shrapnel adsorbed on his chest, Long Guang made a judgment.

The vest must have played a big role! !

Is this the so-called incidental function of a tactical vest?

Can protect against rockets!

Is this function still small? ! !

The three views are directly split! !

Wei Dongren looked like he had seen a ghost.

Blood pressure soars like crazy.

The chin kept trembling.

speechless!

After Mr. Zhan and the students were briefly surprised, ecstasy filled their faces.

Especially the students, their brains were boiling when they saw Xu Fan walking over with an understatement!

His face was full of enthusiasm and he exclaimed with excitement.

"I wipe it, right? It's really okay!"

"Crazy! Everyone is crazy!!"

"What a great senior! The indestructible power of the Vajra!!"

"Why are all the shrapnel absorbed into the vest!?"

"This vest is incredible!"

Xu Fan walked up to the crowd and gently clicked the hide button on the corner of his vest.

The shrapnel attached to the body fell off instantly.

It fell to the ground with a "crash".

Xu Fan smiled and said,

"Everyone, demonstrations are risky, please don't imitate them."

"How is the effect of our tactical vest? Is it pretty good?"

What is this called! !

What does it mean to never imitate? Who else but you can do this kind of thing!

Who would think that except your genius brain! Unless you're crazy!

Everyone is mute!

Staring at Xu Fan's harmless face, I doubt life!

After being stunned for a few seconds, Long Guang suppressed the turmoil in his heart and took two steps forward.

He looked up and down carefully, and after confirming that there was really nothing wrong with Xu Fan, he breathed a sigh of relief.

Also very excited.

This tactical vest is so amazing!

Even bomb fragments that explode close to the face will be firmly attached to the vest at the moment of explosion.

Doesn't this mean that if someone aims a bullet at the head, the bullet will eventually be sucked into the tactical vest!

With this thing, wouldn't Xia's soldiers be invincible?

You suddenly hit me, and all the bullets hit the bulletproof vest!

Nothing happened to me!

I'll give you a chance and you'll become a hornet's nest!

At this time, how should you respond?

If this piece of equipment is mass-produced, it will be good news for the Xia Kingdom’s Fifth Army!

It’s so useful! !

Mr. Zhan next to him couldn't hold himself any longer.

Ask directly,

"Xiao Xu! What's the point of your tactical vest!"

"This... this is simply incomprehensible, how it is possible to do such a weird thing!!"

"Is it science?"

Xu Fan explained,

"This principle is actually simple!"

"I'll tell you a little bit and you'll understand!"

Xu Fan paused briefly and organized his words in his mind.

He glanced around and explained to everyone,

"This is actually, to put it bluntly, alternating electromagnetic induction!"

"The vest has a built-in multi-node giant magnetic source. After being worn by someone, it will scan with shortwave at all times!"

"When metal approaching at high speed is detected, an extremely strong directional electromagnetic force will be erupted in 0.01 seconds, and the warhead shrapnel will be attracted to the vest made of carbyne alloy wire. The impact force caused by the warhead shrapnel or explosion will It will be offset by more than half by the high-frequency vibration electromagnetic array."

"There will be no reaction to metal objects that move away from the body at high speed, such as bullets fired by one's own side!"

Speaking of this, Xu Fan paused.

Gave everyone some time to think and react.

Then he continued,

"Due to material limitations, the bulletproof function has a disadvantage!"

"Nowadays, the warheads of ordinary rifle bullets are steel-lead composite bullet cores, which can be attracted by the strong magnetic field erupted from the giant magnetic source."

"But small-caliber pistol bullets are different. Most of them still have lead cores and cannot be absorbed!"

"If you hit it on the vest, it will naturally be bulletproof. If you hit it on the head, it will explode!"

Xu Fan finished speaking in one breath and let out a long breath.

Looking at Mr. Zhan with sincere eyes,

"You must understand now!"

Mr. Zhan nodded dully, shook his head, the corners of his mouth twitched twice, and his eyes were full of confusion.

I can only understand less than [-]%!

He recalled the fear of being dominated by Xu Fan when he was at Yuntai Naval Base!

Next to him, Long Guang suddenly interrupted and asked,

"Xiao Xu, I don't understand theory or anything like that!"

"But the cases you mentioned of being attacked by a pistol should be rare!"

"Whether it's jungle warfare or urban street fighting, the firepower of pistols is too limited, unless there is nothing else to use! Generally, the starting point for a firefight between the two sides is an assault rifle or even a howitzer and rocket launcher."

Xu Fan nodded, "That's it!"

He didn't know much about this kind of battle between soldiers with bullets and bullets.

Under normal circumstances, he prefers to directly use advanced technology to unilaterally crush and reduce the dimensionality of the attack.

Ordinary firearms are rarely used.

Long Guang asked expectantly,

"Xiao Xu, you just said that this bulletproof function is just a small incidental function. What other functions does it have?"

"Commander-in-Chief! You have finally hit the point!"

Xu Fan's eyes lit up, he lightly patted the black dust on his vest, and said with a smile,

"Let's show you the main functions of this vest now!"

"Cooperating with Fuyou Tianque to realize the ascension system of rapid troop transportation and deployment!"
