With Li Bin's kind invitation, Chen Feng is like a fish and a dragon entering the water, like a tiger with wings!

So, for the next few days, he worked on bombs during the day and went back to make them at night.

Of course, the main reason why Chen Feng dared to do this at night was that the blockade of the house where the explosion occurred had been lifted.

There is no one around, of course, it is Chen Feng's world.

After making the bomb, Chen Feng took a cigarette and went to the mining area to chat with Lao Huang.

After obtaining the bombing schedule, Chen Feng began to test the explosion.

It is no exaggeration to say that every day in the next day, Chen Feng has lived a very fulfilling life!

What followed was a skyrocketing increase in the proficiency of the [Bomb Maker].

……

"Chen Feng, there's a good thing today, do you want to take a look?"

On this day, as soon as Chen Feng arrived at the bomb explosion center, he saw Li Binxing running over in a hurry.

"Good stuff?" When Chen Feng heard this, he immediately became interested: "Take a look!" ”

The good things that can make Li Bin so excited must not be wrong!

Sure enough, when Chen Feng followed Li Bin to the laboratory, he was surprised to find a piece of silver metal on the experimental table.

"What is this?"

Chen Feng was surprised to find that with his cognition, he couldn't see what this thing was.

Bombs?

What material?

"Hey, hey, hey~"

Seeing that Chen Feng was also deflated, Li Bin couldn't help but touch his chin proudly, and then said:

"This is a high-explosive bomb made using reactive destruction element technology."

"Active Destruction Element...... Is it the bomb that can achieve kinetic energy piercing and detonation at the same time? ”

Chen Feng's eyes lit up, and when he looked at the metal block again, it was as if he had seen a treasure.

This kind of technical system is also mentioned, but Chen Feng feels that if he wants to make this kind of bomb, the materials are not easy to get on the one hand, and the ratio between various materials is also a big problem.

But most importantly, there is still no entity to refer to.

Chen Feng was unable to calibrate the specific parameters in reality.

Therefore, this kind of bomb was not in Chen Feng's consideration from the beginning.

But it's different now~

It was placed in front of Chen Feng like this, as long as it was studied a little, coupled with Chen Feng's understanding of this technology, it was only a matter of time before it was produced.

At this time~

Li Bin didn't know what Chen Feng was thinking, and seeing that the other party did not hesitate to say the characteristics of the destruction meta technology, Li Bin directly said a good guy:

"You even know about the Active Destruction Meta Technique!"

Do you want to be so awesome?

"I also came across this report on the Internet by chance."

Chen Feng was vague and perfunctory, and then asked curiously: "How did Mr. Li get such a good thing?" ”

"It's a coincidence~"

Li Bin laughed when he heard this, and said quite proudly: "Didn't I go to the province for a meeting yesterday?" I happened to meet an old friend, and their research group has recently been digging into the scientific value of this project.

No, I'll apply for a little bit of this thing to come back, and see if I can study it in other scientific research directions~"

After saying this, Li Bin came to Chen Feng with a smile: "How about it, help me with the staff officer?" ”

You have to be a staff officer!

Chen Feng almost didn't shout out loud.

But his face remained calm, as if he was facing a very ordinary thing.

nodded: "Cheng, it's nothing anyway." ”

[Bang, study this thing thoroughly, just build one, it's not too cool!] 】

[If you don't activate the next skill, it's intolerable! ] 】

At this moment, Chen Feng has already begun to fantasize about the next skill!

And Li Bin is also a resolute person.

Especially looking at such a good thing in hand, it is simply violent not to study it.

So, the two of them started to study the matter on the same day.

It only took two days for Chen Feng to figure out the structural characteristics of this bomb!

Basically, it is an integral composite solid energetic destructive element prepared by adding a certain amount of energetic powder such as metals, alloys and intermetallic compounds to the polymer powder as the matrix, and then preparing it by special molding and sintering hardening.

With this research and knowledge, Chen Feng immediately set about preparing the materials.

Two days later~

Around the Huaishan No. 2 mining area, in a ravine surrounded by mountains.

Chen Feng took out a two-centimeter square piece of metal from the box, and took out a bomb made by the way.

Immediately after, Chen Feng bound the metal block to the bomb.

"There is no high-speed launcher, and the speed required for impact cannot be reached, but the kinetic energy generated by the explosion of the bomb is definitely enough."

After confirming the porcelain wrapping, Chen Feng clapped his hands with satisfaction.

It is one thing that it is difficult to make a destructive meta-bomb, but it is also not easy to detonate.

The main thing is that he uses inert materials, which will not be detonated unless stimulated by strong kinetic energy from the outside.

No, in order to detonate it, Chen Feng deliberately made a few more bombs.

Just in case!

When everything was ready, Chen Feng glanced at the time - 2:21 p.m.

The next time to blow up the mountain is 2:40.

Chen Feng didn't dare to delay, and after making sure that everything was okay, he quickly ran to safety.

Nineteen minutes later—

Rumble!

With a sound of exploding mountains that resounded in the sky, followed by the earth-shattering roar of mountain rocks!

At this moment, Chen Feng detonated the bomb.

Thundered......

Suddenly, the roar soared into the sky, and the sound of the mountain crumbling and the sound of the mountain exploding converged in the sky.

Merge with.

"Whoa~"

Ten miles away, Lao Huang was playing with his mobile phone at the door, when suddenly a burst of gravel fell above his head.

Bang dang dong ~

Fortunately, he wore a helmet and smashed with a crackling sound!

"Oh my god, is this an earthquake?"

And this sudden scene almost didn't scare Lao Huang to death!

I thought it was an earthquake!

Eventually, he was relieved to notice that the voice seemed to be coming from the No. 2 mine.

"It seems that the No. 2 mine has a very heavy task this month, so hard work!"

Shaking his head, Lao Huang quipped.

Soon, he forgot about it.

After all, this is a mining area, when did you not blow up the mountain?

The little movement just now was just a little bigger than usual.

That's all.

So, Lao Huang continued to lean against the wall, lit a cigarette, and leisurely swiped his mobile phone.

And at this moment—

Chen Feng, who was deep in the mountains, sat on a stone with a depressed face.

Hiss~

Taking a puff of cigarette and glancing at the stone pit produced by the test explosion below, Chen Feng couldn't help frowning slightly:

"When I made this thing, I was 94% proficient, and now that two bombs are detonated together, why can't I break 100%?"

What the hell?

Do you really want him to make a "messenger of peace"?

But that thing, let alone built, is to ask where you can buy "enriched uranium", you have to be targeted, right?

Eventually, a cigarette was smoked without the system moving at all.

Proficiency remains at 96%.

"Damn, I'm happy in vain!"

Putting the cigarette butt in his pocket, Chen Feng stood up scolding.

I thought I could use this to activate the next skill, but now it seems that all TM is!

White rejoice!

"Forget it, it's a bit loud this time, let's pack up and leave first!"

Shaking his head, Chen Feng patted the ash on his buttocks, and jumped to a stone below.

Now is not the time to study why there is no breakthrough, we have to clean up the test explosion site first!

Thinking in his heart, Chen Feng is not delaying~

Na Cheng thought that just as he was about to jump onto the next stone, the system voice suddenly sounded-

[Bombmaker Master's proficiency has been detected to exceed 100%, and the next skill is activated: Antique Trader]
