If you ask Chen Feng: What does it take to make a bomb?

He will tell you: hands.

Just have hands!

For example, at this moment, Chen Feng first gathered the gunpowder together, and then used diluted lime water to make a thumb-sized mold with a hollowed-out middle.

Keep in mind that the mold should not be too thick, and a small hole should be made in the top to facilitate the filling of gunpowder.

Of course, the gunpowder in the artillery battle is not powerful enough, and some picric acid must be added.

Don't forget to add some saltpeter, which is potassium nitrate.

Put these raw materials into the mold according to a certain proportion, and then seal it.

In this process, we must pay attention to the fact that the internal space of the mold must be filled!

It is best to ram it with an iron rod a few times to increase the contact area between the raw materials.

It's even more powerful.

If, at this point, you still don't feel powerful enough, wrap the mold in oiled paper and wrap it with tape.

“OK~”

Looking at the finished product on the table, Chen Feng smiled with satisfaction.

And at this time, at Chen Feng's request, the system voice sounded-

[Bomb Maker Proficiency 2%]

"That's a 2 percentage point increase?"

Chen Feng was a little surprised, and immediately asked, "Then if I do 50 in a row, will I be able to increase my proficiency to 100%?" ”

When the voice fell, the system voice sounded:

[This is just the most basic bomb, staying on it all the time, it can't improve proficiency, it can only delay the host's innate skills and waste life]

"I knew it!"

Chen Feng rolled his eyes directly after hearing this.

Don't you just want to get him to prison~

Just say no?

Still turning so many twists and turns?

"Forget it, don't talk about these useless things, just improve your proficiency as soon as possible and activate the next skill."

In the end, Chen Feng shook his head.

Let's do it with peace of mind!

Fortunately, he prepared a lot of materials, and the materials that Li Bin sent him could make some high-grade bombs.

So, Chen Feng was patient and began to make a second one.

Maybe it was his first time trying this thing, and his theoretical knowledge made him want to get his hands on it.

Therefore, Chen Feng barely rested this night, and made five in a row.

Eventually, because the gunpowder ran out, the lights were turned off and I went to bed.

During this period, when Chen Feng made the second one, his proficiency increased to 5%.

When the third one was made, the proficiency was 8%.

The fourth and fifth, because they are more complicated, need to test the success and specific power, so there is no proficiency for the time being.

……

Jingle bell~

I don't know how long I slept, Chen Feng was suddenly awakened by a rapid mobile phone ringtone.

"Who's calling at this time?"

In the dream, he saw that he had raised the proficiency of the "bomb maker" to 100%, but he was suddenly interrupted, and Chen Feng got the mobile phone with some annoyance.

"Teacher Li?"

When he saw that the caller was Li Bin, Chen Feng immediately came to his senses, and regardless of the interruption of his dream, he answered the phone immediately:

"Teacher Li?"

"It's me Li Bin." On the other side of the phone, Li Bin's voice came, and he asked instead, "Is Xiaoyou free today?" I've got a strange bomb here, and I'd like you to come over and study it. ”

"Okay!"

As soon as he heard that there was a new bomb research, Chen Feng readily agreed.

Hurriedly asked, "Teacher Li, are you in school or the city bureau?" I'm going to look for you. ”

"School, it's still the lab from last time, you just come in."

Li Bin replied.

"Okay, Mr. Li."

Hanging up the phone, Chen Feng did not delay at all.

Dress and wash.

Ten minutes later, I got on my motorcycle and drove away.

Forty minutes later, Chen Feng arrived at the School of Mechanical Engineering.

After that, Chen Feng drove to the science and technology building.

"Hey, why are you here again?"

But he didn't want Chen Feng to just cross a tree-lined avenue, and a person suddenly popped out of his side.

The sudden movement really startled Chen Feng.

But when he saw the person who came, Chen Feng smiled: "What do you think of a fart, you are where I am?" ”

Good guy, it turned out to be Qian Xiuxiu.

Can she bump into this?

"You're the asser!"

Qian Xiuxiu glanced at Chen Feng angrily when she heard this, and then asked with a smile: "Could it be that you are coming to me?" ”

After that, he bumped Chen Feng with his shoulder, and his eyebrows were provocative: "Don't be embarrassed, say it boldly." ”

Chen Feng: "......"

Looking at Qian Xiuxiu with a smug smile on her face, Chen Feng smacked his lips: "Go back and take medicine!" ”

After speaking, he walked towards the science and technology building without looking back.

"Not looking for me?"

Behind him, looking at Chen Feng's distant back, Qian Xiuxiu was a little surprised, and chased after him: "Then what are you doing here?" ”

"Teacher Li Bin invited me to come over."

Seeing Qian Xiuxiu catching up again, Chen Feng replied helplessly.

"Research bombs?" Qian Xiuxiu was stunned.

Chen Feng nodded.

Really!

Qian Xiuxiu directly said "good guy"!

Chen Feng: Is this an addiction to bombs?

Why do you study that thing all day?

Suddenly, Qian Xiuxiu's eyes widened, she walked quickly in front of Chen Feng, and asked in a low voice, "You shouldn't really be making that thing, right?" ”

Chen Feng raised his eyes: "......"

immediately pushed Qian Xiuxiu away.

Unexpectedly, this girl is really accurate in looking at people!

He saw it.

Just as the two of them were talking, they had already arrived at the door of the science and technology building.

Chen Feng stopped at this time and looked at Qian Xiuxiu: "Do you want to go up?" ”

"I'm not interested in that." Qian Xiuxiu shook her head and waved her hand: "You play, I'm going to study the engine." ”

"Hehe~"

Looking at Qian Xiuxiu, who was lacking interest and shook his head and left, Chen Feng smiled and turned around to enter the science and technology building.

After that, Chen Feng came all the way to the laboratory.

As soon as I came in, I saw Li Bin, dressed in a white coat, working on a bomb.

The bomb was fifty centimeters long and wide, with a large piece of thickly wrapped material in the middle, surrounded by various circuits and wiring.

At first glance, it looks like a large circuit board.

"Mr. Li~"

Chen Feng looked away from the bomb and greeted Li Bin.

Li Bin turned around and saw that it was Chen Feng who immediately beckoned happily: "You came just in time, help me take a look at it." ”

Immediately afterwards, Li Bin introduced the origin of the bomb:

"Lao Wang from the bomb explosion in the city next door is on a business trip, and they are in a hurry to issue an inspection report, so they sent it to me."

After Li Bin finished speaking, Chen Feng took a closer look at it, and immediately said: "Isn't this a new type of integrated bomb?" ”

Oh?!

Hearing the words "integrated bomb", Li Bin's eyes lit up.

Then he gave Chen Feng a thumbs up: "Good boy, can you see this?" ”

turned to a joke with a smile: "If I didn't know that your kid is my own person, with your knowledge reserves, I would have suspected that you are a criminal who has absconded!" ”

That's not ordinary!

"I'll just compliment me." Chen Feng smiled, and then looked at the bomb-
