Live broadcast: Teach students to play Three Kingdoms at the beginning

Chapter 438 Learning?We are playing!

After Awei's "free" dedication, the other high school students in Europe immediately imitated the example and looked at the other students in Class Nine with a little longing in their eyes.

Such a scene immediately made the corners of Class [-]'s mouths twitch twice.

There was also a little pain in the eyes looking at Awei.

You said you were fine, why did you say that?

It's all right now, what else can we do after looking at her innocent but yearning eyes?

reject?

He came here with a gift anyway, and the atmosphere is so hot, can we refuse?

After greeting Ah Wei cordially in their hearts, everyone in Class Nine could only smile and say at the same time:

"Why don't we give you this set of Hanfu as a reminder?"

As soon as the words fell, the high school students in Europe immediately said skillfully:
"What a shame~"

Then the European high school students collectively tightened their Hanfu in the midst of the voice of 'rejection'.

Afterwards, it seemed that they still felt unsafe, so they simply asked to change their clothes back, and the reasons they gave were quite impeccable.

[We are not worried about you taking back your clothes, the main reason is that such gorgeous clothes will be bad if they get dirty later. 】

Regarding this kind of rhetoric, what else can everyone in class nine say? Naturally, they can only choose to agree, and they are very considerate and sent a Hanfu packaging box.

Although they felt a little helpless in their hearts at this time, they actually didn't have much dissatisfaction with the matter of giving away Hanfu.

Anyway, they basically don't wear these Hanfu, so it's not a big problem to take it back and forth now.

After such a simple play, the European high school students have had enough of the Hanfu addiction. While changing back to casual clothes, they also have a new understanding of Longguo Class Nine.

These guys are not only warm but also generous~
The Hanfu, which looks so expensive, is actually given as a gift!

It was sent out voluntarily, almost under the circumstances of their 'lure', which made them feel deeply about the minds of these Longguo Class Nine students.

What a group of nice people~
After this episode, everyone in Class [-] of Longguo and European high school students became more and more harmonious.

During a chat, the European high school students said that they could not waste their New Year here in vain, and they still had to do what they should do, and then asked what Class [-] was going to do next.

Is there any project they can help with.

The students in class nine still welcome this kind of free labor.

Immediately, Ah Wei took out the Spring Festival strategy prepared a few days ago, and explained to the European high school students while flipping through it:

"This New Year, we put the main leisure time at night, which is the time for New Year's Eve dinner."

"At that time, not only will there be individual performances, we will also hold some competitions, and we will offer New Year's blessings to the unlucky losers~"

"Of course, what this kind of blessing is depends on our mood."

"And this kind of programs and competitions are not predetermined. They are determined by drawing lots. Whatever lottery is drawn, the program will be performed."

"In addition, after the New Year's Eve dinner, we will also hold a firework show, amidst the explosion of fireworks, we will welcome the bell on New Year's Eve."

"So, based on these points, you can still do a lot of work now."

"Either, help that boy Li Cheng prepare the ingredients for the New Year's Eve dinner, or find ways to provide some interesting programs or sharpen his guns to strengthen his comprehensive ability."

"After all, those 'signatures', to be honest, we don't know exactly what insane things are written in them."

"Other than that, all that's left is to help us dismantle the fireworks and finally ring the bell at 12 o'clock in the morning."

"Let me tell you in advance, the job of ringing the bell looks simple, but it is actually a bit tiring."

"Although the clock we bought this time is not too big or too heavy, the person who rings the bell must strike a full [-] times, otherwise, it will be unlucky."

"What kind of statement is this?" Hearing what Awei said, Borg asked a little puzzled, "I mean strike the bell one hundred and eight times."

"Oh, easy."

Ah Wei explained:
"This number mainly comes from the traditional calendar of the Dragon Kingdom. There are twelve months in a year, 24 solar terms, and 72 periods. When these numbers add up, it is exactly one hundred and eight."

"Knocking all these one hundred and eight times means that there will be no troubles or troubles in the new year."

"So this matter is still very important to us Longguo people."

After all, Ah Wei glanced at the European high school students who suddenly realized.

"It turns out that there is such a saying. It's quite interesting." Elson nodded, and then asked another question:
"That"

"What did you plan to do when you said you were dismantling the fireworks?"

"I see that you have bought enough fireworks. It should be enough to hold a fireworks show, so why do you need to dismantle them?"

As he spoke, Elson looked at the pile of fireworks that he had been paying attention to just now, and the gunpowder in the corner
No matter how he looked at it, he felt that it was dangerous.

Especially when there are several fire extinguishers next to it.

Just let this sense of danger turn a little bit in the direction of horror.

Hearing that, before Ah Wei could speak, Li Qi next to him slapped Elson's neck with a slap:

"Hey, what else can we do, let's make a firecracker ourselves."

"Fireworks show, although it's fireworks in name, it's not loud enough."

"It's the traditional firecrackers of our Dragon Kingdom that really matter."

As he spoke, Li Qi showed a reminiscing expression:

"I don't know, have you heard of Er Tijiao and Mariezi?"

"This stuff, our kid will always play it."

"It's not an exaggeration to say that the sound shakes the roof tiles. Compared with the noise of fireworks, Mariezi and Er Tijiao are the things that real men should put."

"Especially marizi, which is used to fry fish in the water. It is fried accurately. As long as it is ignited and thrown into the water when it is about to explode, those fish will immediately turn up."

"It can be said to be a must-have item for barbecues."

"As for the second kicker, although it's not as powerful as a marijuana, it's like a small rocket with a second-stage propulsion device."

"It's so good to hear it explode in the air."

"What we want to do is this kind of firecracker."

"What's the point of a girly thing like setting off fireworks?"

Seeing Li Qi dancing and dancing, as well as the boys from Class [-] who were also excited and the girls who were a little helpless, the European high school students were numb.

If they heard correctly, these guys want to use gunpowder to make fireworks with certain lethality?
And it's already on the way to production?
The gunpowder in the corner is the process?
Do these guys have some misunderstanding about fireworks?

Is this something that high school students like us can make?

Don't they know gunpowder is dangerous?
They are still on this wooden boat, so they are not afraid of accidentally ordering the boat?

Also, what about their homeroom teacher, why don't they talk about it? !

Subconsciously, these European high school students began to search for traces of Ren Yan, but when their eyes caught a glimpse of the fire extinguisher again, they were confused.

Maybe, maybe.
These guys are actually
Unexpectedly calm?
"Even if you want to do it. But isn't it a bit too dangerous?"

"Gunpowder is so easy to control."

Borg couldn't help but twitched the corner of his mouth a few times, and asked:
Hearing this, Wang Bo on the side waved his hand:

"Hey, what's the problem?"

"We are not making real explosives, nor are we making traditional black powder such as mononitrate, disulfide and charcoal."

"We're just improving on fireworks and gunpowder."

"Although the current fireworks and gunpowder still belong to the ranks of gunpowder, they have long been neutered from the function of explosion. If you light the gunpowder, at most a little spark will be released, which will not cause any danger at all."

"If you improve on this basis, the risk factor is very low, and there are basically no uncontrollable situations."

"But your target wasn't explosives in the end?"

"Isn't this thing dangerous?"

Borg continued to ask questions.

"That's why we prepared fire extinguishers in advance."

Wang Bo shrugged and glanced at the fire extinguisher again.

For a moment, Bogton felt powerless.

Fine
What this guy said makes sense.

"Okay, in fact, you don't have to worry at all."

"This kind of thing is very common in our ninth class."

"We are not stupefied, we have to do it if we say we can do it."

"We are still very clear about the principle of the two firecrackers that I told you just now."

Seeing that Borg and others were still a little timid, Wang Bo began to explain seriously:
"If a firecracker wants to explode, almost all the power it needs comes from the gas volume diffused when the gunpowder burns."

"As long as we control the amount so that it can just break through the cannon skin and form a crisp sound, it will be considered a success."

"I understand the truth, but the question is, do you have parameters?" Borg scratched his neck in doubt.

"No~" Wang Bo replied seriously.

Borg staggered when he heard this, and immediately wanted to educate the other party about the difficulty of this matter, so that they could dispel this bold idea.

It's fine to set off ordinary fireworks, why do you have to do some firecrackers?

However, at the moment when his idea was just born, he saw Wang Bo skillfully took out a notebook from his back waist, opened it, and began to talk eloquently:

"But parameters, it's not difficult to obtain."

"We can now use the thermal expansion formula to calculate the expansion force of the fireworks and gunpowder, and then calculate the bearing capacity of the cannon skin we made."

"Then with a little division, we can get the optimum amount of gunpowder."

"But considering the volume, we also have to optimize the ratio of fireworks and gunpowder."

"There is no tricky way to do this. We can only calculate the amount of gas emitted by burning bit by bit."

"For this, we have prepared the flasks in advance."

"So as long as you think about it carefully, it is not very difficult to launch a perfect new ratio through fireworks and gunpowder."

As he spoke, Wang Bo wrote a few more strokes in his notebook, and then handed it to Borg.

Borg took it in a daze, and then he froze.

In this notebook, a dense pile of formulas and chemical equations have been written down, and there are even composition diagrams of gunpowder next to it, as well as some basic parameters of firecrackers.

The complexity of these formulas made Borg, a top student in Europe, a little confused at first glance.

If it weren't for his good foundation in mathematics, physics and chemistry, he wouldn't even know what the other party wrote.

But even so, Borg only understood the underlying principles of these formulas after carefully reading them two or three times and combining them with Wang Bo's explanation before.

These guys really want to make such a firecracker.
Also, it looks very professional.

Come on, are these guys really high schoolers?

Borg subconsciously raised his head and glanced at everyone in Class Nine, feeling a little flustered in his heart.

He remembered that when Wang Bo said these things just now, the other Longguo students didn't have any doubts on their faces, but took it for granted.

Doesn't this mean that these guys have a very high understanding of this kind of comprehensive mathematical, physical and chemical problems? !

Although it is often said that the students of Longguo are the pride of heaven in terms of grades, but
Isn't this situation a little too outrageous now?
After a short period of entanglement, Borg looked at Wang Bo's notebook again, this time he no longer looked at the previous formulas, but the schematic diagram behind.

There, Wang Bo has already drawn the schematic diagrams of Ertijiao and Mareizi two kinds of firecrackers.

There are even various parameters and basic information required next to the schematic diagram.

Among them, most of the things are half-knowledgeable, but next to the schematic diagram of the second kicker, he can still see the air pressure formula and the force diagram of the second kicker drawn according to this formula.
This scene made Borg completely numb.

Originally thought that these Longguo students only had extraordinary skills in the professional field.

As a result, the other party's job as a student is even better than his professional field?

What kind of freaks is this bunch of freaks?
Borg looked at everyone in Class Nine dumbly, his hands loosened, and the notebook fell on the table.

Seeing this, Elson next to him took Wang Bo's notebook and looked at it. After a while, he also looked a little melancholy, and even in his melancholy, there was a bit of doubt about life.

The reaction of these two immediately made the rest of the European students curious.

After Elson, they simply spread Wang Bo's notebook on the table and watched it carefully.

Shortly after.
All the European students froze in place, and there was no response for a long time.

They are wondering and curious.

Why are these guys able to do such outrageous things when they are all high school students?

And even if the light is outrageous, why does it seem to be so practicable!
Are you joking about what Wang Bo said just now?
European high school students are feeling the blow inside.
After a while, Leo subconsciously swallowed his throat and looked at Wang Bo:
"In your class, after all, you have this idea yourself."

"Or do you all have a common understanding of how to make firecrackers?"

"Can other people understand these formulas?"

"That must be understandable~" Wang Bo took it for granted:
"I'm at the bottom of our class in terms of design calculations."

"I can figure out these things, don't talk about them."

"If our university overlord Yu is here, I think that guy can probably design the second kicker into a small rocket~"

Hearing such an answer, and looking at the normal reactions of the surrounding Longguo students, Leo suddenly felt a little heartbroken.

It seems that my group of European high schools are not a little bit worse than these students of Longguo Class [-].
These guys are all interested in researching rockets, and they are still struggling with what to do next
Is there any reason for this?

Suddenly, Leo wanted to cry
Also have some regrets.
How do you compare your group of people with these guys~
However, after deliberating for a while, he still asked his own curiosity:

"Could it be that you usually study like this?"

Hearing this, everyone in Class Nine was taken aback, and blinked suspiciously:
"study?"

"No"

"Now it's all our personal will, does it have anything to do with learning?"

"We are playing~"

"Don't you think it's fun to save a second kicker?"

'Play? ! '

'Fun? ! '

'A lot of fun? ! '

Listening to Class [-]'s answer, the European high school students were completely convinced
In their eyes, the comprehensive mathematics, physics and chemistry problems that are fatal, in the eyes of these Class Nine students, are they just playing?
Do these guys misunderstand playing, or do they misunderstand learning?

In other words, people have gotten rid of the low-level fun of karaoke and disco, and started to have a higher spiritual pursuit?

Moreover, if you really look at their process from scratch.

It seems that the matter of saving a firecracker by myself is really a big deal.
Quite fun?

Involuntarily, the European high school students looked at each other in blank dismay.

Moments later, they made a request:
"or."

"Making Er Tijiao and Mareiko a little bit involved?"

"Have fun~"

"We want to play too"
