No.30 three sessions, exercises

With smart people, life will be simple and smooth.

There are no contradictions that can block everyone's hearts.

There are no trivial matters.

It seems that everyone is generous, or in other words, very structured.

And if everyone is like that.Then the group will be very harmonious.

Everyone works so hard and lives so hard.

There is no time to waste on insignificant things.

In other words, there are more happy things that need these time.

Weekends are always so short.

No matter in that environment.

This is true in the army, and it is also true in college towns.

But no one seemed to think about what they did yesterday.

Everyone is thinking about what to do today.

Or what tasks will be done tomorrow.

It's just a new week and it seems to be different again.

It's a different mentality.

Yes, and I just came to this place, and now, it can be said that I am very familiar with it.

Life seemed better.

Duang Duang

Two shots were fired.

Hairy standing.

This was Xinghe's first reaction.

Who, who set off the signal flare.

Xinghe looked back at the place where the gun was shot.Rolling my eyes inside.

"Assemble. All assemble." Gathering up the team was Xinghe's first order.

Then the air defense siren sounded instantly.

Woo~woo~woo~

From here to there.

Emergency evacuation?

It's all in the playground, what's the fuss.

"Air defense drills, emergency drills. All of them are in combat."

The commander yelled through the loudspeaker.

After hearing this, Xinghe relaxed instead.

Because this is really trivial.

We soldiers usually have no organization on any occasion.

Training is simply the norm.

And now they are college students.

That's easier.

It can be clearly seen that university students cannot achieve the level of our soldiers.

Whatever we do, we are much stronger than them.

And they certainly haven't been through various organizations.

This time they must be dragging oil bottles.

Don't think about it, you can become their leader by doing whatever you want.

Just play with them and be careful.Not surprisingly, it was time for a walk.

And it seems that everyone does not have this awareness.

It's all very easy.

"Did you see the signal flare just now?"

"Yes, got it."

"what colour?"

"Red and green."

"Why red and green, can you explain it with your chemical knowledge?"

This question was asked abruptly.

I guess nine out of ten are in a state of bewilderment.

"You are all college students, didn't you study chemistry in high school?"

"Instructor, there is no such thing in the chemistry we study."

"Think about it, just like magnesium burns and emits dazzling white light, iron burns violently and emits a lot of heat, and sparks radiate to produce black solids. These are all high school knowledge."

"But it doesn't seem to say which ones are red and green."

"Yes, hey, how did you get here in high school?"

"A summer vacation made you forget what you learned before?"

"Actually, chemistry learned in high school is very common in daily life."

"For example, shampoo, body wash, they all contain benzenesulfonic acid, sodium dodecylbenzenesulfonate, sodium lauryl sulfate."

"To expand, long-term use of sodium laurate sulfate, alkyl sulfate, and sodium lauryl ether sulfate can cause skin peeling, redness, swelling, and even sensitivity. Continuous use of sodium lauryl sulfate will destroy skin proteins and damage the integrity of the "skin barrier." Sex "brings lasting damage."

"There is another point that everyone should be familiar with, that is, some shampoos and shower gels share toxic substances. It's just that there are too few such things happening in daily cosmetic products, and everyone ignores them."

"Instructor, you understand this too."

"Is it okay if you don't understand? If you don't understand this, how to make a simple bomb."

"Bomb?" Everyone cheered up.

"Is this unexpected? You must be familiar with these things during special operations."

"Instructor, do you have to learn this as a soldier?"

"The types of troops are different, and what you learn is also different. It depends on whether you seem to learn."

"It feels so hard."

"Tch, the flare glows red because it contains strontium. It glows green because it contains barium or potassium."

"Don't tell me that I don't know that potassium element burns and glows green."

"I know that. I also know that sodium element burns and emits yellow light."

"Yes, it's that kind of yellow signal flare, which contains sodium element, which wasn't there just now, and you haven't seen it before."

"These are all the simple signal launches we can make in normal times. There is also a white signal flare, which I have never seen, but I have used it."

"Its content is the nitrate of barium and potassium. If you are interested, you can play with it. Of course, these are also very common in daily life. Sprinkle salt on the fire, and the flame will turn red. It is the same reason."

"Can the instructor make a bomb?"

"No, it's too dangerous, but if you are interested, you can teach in private."

"Instructor, I mean can bombs really be made out of these?"

"Of course, for example, the ingredients of soap include the sodium salt of carboxylic acid R-CONa, antioxidants, foaming agents, hardeners, thickeners, synthetic surfactants, etc., etc., etc."

"There are also common synthetic colors, synthetic fragrances, preservatives, foaming agents, these, among them are fatty acids, hardened oils, glycerin, etc."

"These can be the ingredients of bombs. You should have heard of Tingti. His ingredient is [-]□□, which can be synthesized from toluene, nitric acid, sulfuric acid, and sodium sulfite. Look at the raw materials I mentioned. Can you find it in your life?"

Having said so much, in fact, in reality, it is really not easy to make it.

"Of course I'm telling you all this, just to relieve boredom. The production process is quite complicated, and the bombs produced are not as powerful as you think."

"The energy they produce is not as much as the heat produced by coal mines. One kilogram of Tingti can produce 4226 kilojoules of heat when burned, but one kilogram of coal can produce 8912 kilojoules of heat."

"Ah? Why is that? Shouldn't the explosion have more heat?"

"Limitations, many things are not what you think."

"There should be a speed. The speed of burning."

"Yes, there will be such a huge difference in effect, mainly because the burning time is different. A kilogram of coal burns for several minutes or even longer. If it is made into coal powder, it will float in the air and be fully combined with oxygen. It’s quite powerful. But for a ladder, it only takes one ten-thousandth of a second, or even less, to burn a kilogram.”

"This energy, which has nowhere to put it, explodes when it is transferred." He made a sad expression.

"Ah, my charm that has nowhere to put it." A girl continued.

There was laughter.

"Of course, now that the society is stable, there is no need to learn this anymore, and we often destroy ammunition."

"The way the gunpowder burns is very similar to love."

"What does it look like?"

"I burn myself without reservation in an instant. I don't even give you time if you want to grill a skewer."

haha~

"Instructor, you are so funny."

Gunpowder is actually very simple. If readers may go to special operations units in the future, they can feel it when they learn gunpowder.

I won't show my ugliness.

And this is mainly chemical knowledge.

In this novel, I can't write too much.

Those who understand can see it clearly at a glance, and those who don't understand can't understand it no matter what.

And I remind everyone that in practice, if there is pressure and psychological burden, you can add a little more desensitizing agent, such as water, oil, paraffin, and Vaseline.

In fact, the bomb is not so terrible.

I will not waste space here.

Let's talk about these things if necessary in later chapters.

"Follow the team in front and walk in unison."

Jokes are jokes, drills and drills still have to be carried out.

It's just that this training that makes everyone too tired to walk is really just for fun for us.

No weapons, no time limit, no speed limit, and honestly, we didn't take it seriously.

I don't even want to waste pen and ink to write the whole training process.

I don't even want to write about the transmission of various passwords and the reactions to various things, because these are really games with what we usually do. . .

After writing this, I am worried that in the following chapters, I will leave a vague impression on the readers in advance.

After you have experienced a [-]-kilometer armed training in a day, these walks are really fun.

wrong.

It should be enjoying the scenery.make a sightseeing tour.

After all, the campus environment of Fuzhou University is still very beautiful.

Rare opportunity to wander around this campus.
