Feelings are always sublimated unconsciously in communication.

In addition to teaching students, Xu Jie and Zhou Yutong unexpectedly had more topics in common.

This made the two of them appreciate and love each other even more.

I like it at the moment, it's very simple.

It’s not easy to be with you forever.

This is true for people, things, and objects.

…

Early the next morning, Xu Jie flew back to the island.

Randomly brought along were some gadgets that Chu Mo tinkered with.

The last time Chu Mo participated in the competition, the explosion protection device he made was an umbrella-shaped object.

Chu Mo named it FB-01 himself.

FB is the acronym for explosion-proof, and its meaning is self-explanatory.

FB-01, its design concept is only enough to withstand ordinary firecracker explosions.

Therefore, neither the materials nor the acousto-optical induction are very sophisticated.

When the surrounding explosion sound reaches a certain threshold.

FB-01 will unfold on its own like an umbrella to protect people within the explosion range.

At the same time, sound-absorbing materials have been added to the interior of FB-01.

Xu Jie and Chu Mo had done experiments before.

Even within one meter of the explosion range, its silencing effect is very good.

If it weren't for the fact that the cost of this thing is too high.

Xu Jie actually thinks that this small invention can be used by people who are afraid of the loud explosions of fireworks and firecrackers but want to play with them.

There are many people in this world who have been frightened by the loud explosion of firecrackers.

There are even more people who dare not set off firecrackers because they are afraid of explosions and loud noises.

You can have fun setting off fireworks and firecrackers, and you can also ensure 100% safety. The key is that they are not expensive.

If this thing really exists, Xu Jie thinks there will be a market.

The novel invention Xu Jie brought back to the island this time was the upgraded version of FB-02 that Chu Mo made with Wu Feng during the summer vacation.

From the outside, it no longer looks like an umbrella, but like an ancient shield.

The height is about seventy or eighty centimeters, and the width is about forty or fifty centimeters.

It can be carried in the hand or stood on the ground.

The material used to build this device is a certain alloy selected by Chu Mo and others from the laboratory.

Xu Jie doesn’t know the specific effect yet.

Not only did he not know, Chu Mo and Wu Feng, who made this equipment, also did not know its actual effect.

Once they arrived, they had just finished making it and hadn't had time to experiment yet.

Secondly, the original intention and concept of the design was to protect against the power of grenade explosions, and they did not have such powerful explosive experimental items on hand.

They just told Teacher Xu.

Both the materials used and the built-in explosion sensors have been upgraded.

This actually made Xu Jie very curious and expectant.

When Xu Jie returned to the island, Du Yan and Lu Junwu were fighting Xu Sanduo.

All three of them were in the ring, Du Yan and Lu Junwu were fighting two against one.

Xu Jie watched it with great interest for a short while, then suddenly found it boring.

Xu Sanduo is not a human being.

His ability to react when exposed to threats is not comparable to that of today's Du Yan and Lu Junwu.

Although the cooperation between Du Yan and Lu Junwu has become more and more tacit, they even do not hesitate to use very cruel and unconventional attacks.

But in the face of Xu Sanduo's impeccable defense, it was still not enough.

Xu Jie was really looking forward to seeing how much the strength of these two boys could increase after giving Xu Sanduo such training.

When you really go to the army next year, why shouldn't you shock the recruit company?

Xu Jie thought happily as he came to an open area outside the base.

Behind him were two other intelligent bionic robots from the base.

"Dazhuang, take this shield and do an experiment."

Xu Jie smiled and handed FB-02 to an extremely strong robot next to him.

This robot, just like the T-800 in the Terminator starring Schwarzenegger, is tall and powerful, with a strong back and a strong back.

The difference is that he does not have a Western face, but an Eastern look.

Xu Jie named him Xu Dazhuang.

Xu Dazhuang took the shield-shaped FB-02 and nodded grimly.

In his other hand, he also held a small oval-shaped grenade.

This is an M57 model grenade.

The total length is 9.9 cm, the diameter is 5.7 cm, and the weight is 454 grams.

The effective killing radius is 15 meters.

Among grenades, they belong to the category with greater lethality.

Xu Dazhuang walked steadily 50 meters away.

Hold FB-02 in your left hand, and pull the metal ring of the grenade with your right hand.

He threw the grenade casually and nonchalantly on the ground less than one meter away from him.

5,4,3,2,1.

Bang!

The moment the grenade exploded.

I saw the FB-02 on Xu Dazhuang's left hand spread out like a curtain in an instant.

In front of Xu Dazhuang, a hemispherical protective shield was formed to protect him inside.

50 meters away, Xu Jie, who was hiding behind the bunker, only heard a huge explosion, and then saw mud and gravel flying.

A big crater was blown out of the ground.

Xu Jie was secretly speechless.

Fortunately, Xu Dazhuang did the experiment.

If a flesh and blood body were in the center of the explosion, without protective equipment, it would definitely die without any body parts.

Soon, Xu Dazhuang returned to Xu Jie with FB-02 that had not retracted to its original shape.

Xu Jie walked around to the side facing the explosion.

There are many traces of explosion burns on the hemispherical protective cover.

But overall, it is not damaged or broken.

“How is the data collected?”

Xu Jie asked Xu Dazhuang while observing.

"The temperature at the center of the explosion peaked at 2784 degrees."

"The peak sound of the explosion was 147 decibels."

"The temperature peak behind FB-02 is 51 degrees."

"The peak sound of the explosion was 56 decibels."

"In addition, the effect of shock absorption and impact resistance is also very good."

Xu Dazhuang replied with a cold face.

His voice is not mechanical, it sounds just like ordinary people.

Xu Jie was pleasantly surprised when he heard his answer.

Being able to collect these experimental data was his main purpose for allowing robots like Xu Dazhuang to conduct experiments.

Based on these data, Xu Jie generally knew the feasibility of this equipment.
