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

Chapter 381 The New Mission of Class Nine, Travel Guide [6300, full order]

"Is there a problem with the material?"

Hearing this, Krell immediately pulled himself out of the entanglement, looked at the Longguo student not far away and asked back.

"Yes, there is something wrong with the material." Xu Kai nodded and continued: "In my opinion, there is no problem with your workmanship."

"The reason why the airbag can't be flushed is simply because you gave too much material to the airbag."

"My suggestion is that you should remove two more layers."

"But after removing two layers, the entire airbag is completely exposed to the inner lining, which not only has the possibility of damage, but also affects the appearance."

"You have to know how hard it is to find an airbag that is the same color as the lining and looks seamless."

Hearing this, Krell shook his head noncommittally, and was going to continue to study the improvement plan.

But just as he lowered his head, Xu Kai said again:

"Now that you can't even achieve the most basic use, do you care about the beauty?"

"Are you making this thing for use, or for aesthetics?"

As soon as this remark came out, Claire paused for a moment.

He found that he really seemed to have entered a dead end.

Yup
The things you make are mainly for use. Is beauty really that important?

"However, the beauty and practicality you mentioned are not impossible to combine."

"How to combine?!" Hearing this, Krell's eyes lit up, and he walked to Xu Kai's side in two or three steps, staring at him with burning eyes.

Although he still doesn't know the origin of this Dragon Country man.

But there would be no problem with the people Laurie brought.

And the other party seems to have two tricks?

He has used all his efforts in this surfing suit, and it would be great if it can be improved now.

"Didn't you just mention the safety of airbag exposure?"

"This can indeed be combined with beauty, but the design of your surfing suit may have to be completely reinvented."

"The design of your current surfing suit is too slim, and the position of the airbag is completely close to the chest. If the material is not up to standard, it will indeed cause unnecessary danger."

"And for the sake of aesthetics, the inflation valve of the airbag is too small. Under the pressure of the ocean and the limitations of materials, it is really difficult to inflate."

"So to solve this problem, I suggest you change the position of the inflatable bag."

"Change position?" Hearing this, Krell hesitated for a moment: "Where might it be changed?"

"From a scientific point of view, the buoyancy device located on the chest is the most effective, and those big-name lifejackets are all this way."

"You also said that it is a life jacket."

"But what you're doing now is surfing suits, so it's not a concept at all, okay?"

After begging his mistress to translate Krell's words for him, Xu Kai struggled to answer in English again.

He found that his English seemed to be at its limit.

After the first few words, it became more and more difficult for him to communicate with the other party.

Vocabulary is too small.

Seeing Xu Kai's tangled appearance, Zhang Ting fortunately acted as the translator for the two again.

"Then where do you think it fits?" Claire asked.

"Abdomen." Xu Kai replied earnestly: "Not only is the abdomen located in the same position as the body, but the space it can accommodate is much larger than the chest cavity. After all, the abdomen does not have hard bones."

"But the abdomen, can it really make people float up perfectly?" At this time, Claire still seemed a little hesitant.

He even compared his abdomen, with a little confusion in his eyes.

This thing is a portable inflatable bag, not a swimming ring, and it doesn't have that much space.

Can the buoyancy of the abdomen alone really make the person who falls into the sea safe?

Claire couldn't believe it.

Seeing this, Xu Kai didn't bother to talk nonsense, and directly asked Laurie for a pen and paper, found a place and started his drawing work.

After a while, Xu Kai drew a sketch of a human body.

Although I can't draw a picture scroll according to my own feeling like Zheng Chen.

But as the deputy chief designer of Class Nine.

For the drawing of the structure of some objects that can be seen everywhere, the current Xu Kai is very clear.

After drawing, Xu Kai immediately started calculations on it.

From the buoyancy required by the standard weight of the human body, it is calculated to the buoyancy produced by carbon dioxide.

From these two buoyancy calculations, the required toughness of the airbag material is calculated.

To this end, he also assumed a lot of variables.

Finally came up with an answer:
"You see, in terms of ergonomics, the inflatable bag at the waist can also play the same buoyancy effect, and it will not make the human body deviate."

"Although the effect may be worse, these can be corrected through materials."

"In this way, the problem of small space can be solved."

"And in the future, airbags with different buoyancy can be made according to different body shapes. As long as you choose the airbag that suits your weight most, you can completely get rid of the disadvantages of your current surfing suit."

Looking at the densely packed drawings and formulas in front of me, I listened to Zhang Ting's instant translation.

Claire was full of question marks.

Pointing to the picture and pointing to Xu Kai, he said a word for a long time.

In the end, he had no choice but to look at Laurie, and said in a daze:
"Laurie, are you sure we're not dreaming right now?"

Hearing this, Laurie frowned, walked to Krell's side in a few steps, raised his right leg and gave him a kick.

He wanted to kick this foot for a long time.

Now that the other party has given him a chance, Laurie didn't hesitate at all.

"Oh God, what are you doing?!"

Krell, who was kicked in pain, immediately glared at Laurie.

Laurie shrugged innocently: "Didn't you ask me if I was dreaming?"

"Since you can feel the pain now, it means you are not dreaming."

"Is there anything wrong with me doing this?"

Hearing this, Claire glared at Laurie: "I can see that you are avenging your own personal revenge!"

Laurie nodded seriously.

Seeing this, Claire sighed silently, then looked back at Xu Kai, and tremblingly said:

"Then here comes the problem."

"Where did you find these freaks!"

"How long has it been? This Dragon Country man has actually completed a whole set of comprehensive questions, and even solved a problem with this comprehensive question."

"Can our practical teacher do this?!"

"He didn't tell me that there was something wrong with my surf suit!"

"In fact, he didn't even see it!"

After confirming that he was not dreaming, Krell dragged out all his doubts.

In fact, the moment Xu Kai finished his calculations, he began to doubt his life.

The Longguo man in front of him looked about the same age as himself.

But he easily did what he couldn't do.

All these signs point to one thing, if there is no accident, this Dragon Country man is his mother's superman!

So, at that moment, Krell was confused.

For the first time ever, the world was questioned.
What I received was noble education, but when did Dragon Kingdom have noble education? !
Seeing this, Laurie pouted in Class Nine with disdain on his face:

"Tch, look at your face that has never seen the world."

"Do you understand these are basic exercises? Basic exercises~"

"This kind of operation can only be regarded as mediocre among these Longguo students. You haven't seen that person's calculation ability~"

With that said, Laurie patted Wang Yu's shoulder naturally:

"This brother, when you are in a hurry, you can do mental calculations."

After that, Laurie looked at his best friend with a smile.

I was so happy, I even had a little bit of gloating, and I was honored.

These people knew each other in advance!

In fact, Laurie wasn't surprised by Krell's current reaction, but thought it was normal.

After all, during his time on Class No. [-], he had seen many such scenes.

There are even some more exaggerated operations.

It has long since changed from shock at the beginning to numbness now.

But now seeing that his best friend's expression is exactly the same as his original self, Laurie feels sincerely happy.

"Maybe this is the so-called best friend~" Laurie nodded contentedly.

But Claire's whole body became sluggish.

Looking at the calm faces in front of him and Laurie's haughty look, he knew that Laurie's words were probably true.

Otherwise, who could be so calm after seeing this scene!
Silently, Krell swallowed his throat, and his mind began to spin rapidly.

After digesting the explosive information for a while, he grabbed Xu Kai's hand.

With affectionate eyes and a sincere tone, he slowly said: "Brother, do you want to work with me to finish this surfing suit?"

"You get half of the results."

"No, you accounted for [-]% of the results!"

"I just want to fulfill this dream of mine!"

While speaking, Krell blinked his eyes in a two-dimensional way.

Goosebumps all over Xu Kai's body, he shook off Claire's palm without saying a word, and then looked at his teacher.

His eyes were full of questions.

Seeing this, Ren Yan shrugged indifferently, saying that Xu Kai can decide this issue by himself.

At the same time, he also had a general understanding of this person named Krell.

Judging from his reaction, this person's thinking is very sharp, at least much better than Laurie.

Back then, Laurie didn't have this kind of reaction.

Moreover, this idea of ​​attracting resources is also very 'capital'.

However, it is very different from pure capital.

This person is willing to give up most of the benefits, which has already made him out of the ranks of 'capital'.

Although I don't know what will happen in the future, but now it seems that at least the other party is still a teenager with a dream.

Seeing his teacher's casual attitude, Xu Kai thought for a moment and nodded. He was indeed interested in this surfing suit, otherwise he would not have said something to him at that time.

But even so, Xu Kai still put forward a condition:
"Promise is not impossible"

"But I have one condition."

"What conditions?" Claire asked hastily.

"When we cooperate in the future, you change your clothes."

"Your current suit is too eye-catching."

As he said that, Xu Kai swept Claire's clothes with disgust.

"Is this suit ugly? I think it's pretty good~"

Hearing this, Krell spoke hesitantly.

Xu Kai immediately refuted: "It's ugly to death."

"And it's weird."

"In these days, who would go out wearing a beautiful girl~"

"Don't you feel ashamed?"

Speaking of which, Xu Kai also asked a question that everyone in Class Nine was curious about:
"And how on earth did you form such a wonderful aesthetic?"

Listening to Xu Kai's complaints and questions, Krell sighed silently, his eyes gradually became deeper, as if recalling the past.

After a long time, he opened his mouth slowly, and the vicissitudes in his tone were completely different from his age:
"Thinking back, it was still in my childhood."

"At that time, I could still see all kinds of beautiful big sisters on TV and the Internet, and I was gradually completing my aesthetics."

"But many years later, I suddenly discovered that those beautiful big sisters on the Internet and TV have disappeared."

"Instead, there are some very unique people, and even the beautiful women are no longer seen in the game."

"I think at that moment, my aesthetics have changed a little bit."

"Until later, I met Two-dimensional, which was like a beam of beautiful light, dragging me out of the quagmire before."

"Since then, I have been hopelessly in love with Two-dimensional."

"It is my salvation~"

"However, since you guys find it awkward, it's okay if I don't wear it when we cooperate."

After all, Claire's eyes still showed emotion, and he immediately agreed to Xu Kai's request.

But after hearing this short story, everyone in class nine looked at Krell sympathetically.

See what it's like to force the children.

Everyone is starting to like cardboard figures!

Unexpectedly, the country of Stars and Stripes, far away across the ocean, is still in such dire straits~
On the side, listening to the memories of his best friend, Laurie also sighed silently.

For this situation, I felt heartbroken.

After all, he must be considered a victim of this situation.

After a while of silence at the scene, Niu Pu took the lead to withdraw from his sympathy, looked at his teacher, and asked:
"Mr. Ren, it doesn't seem to matter to me."

"Can I go out and buy two books first, my mind is full of trying to solve that mystery now."

Hearing this, Ren Yan thought for a while and nodded: "That's fine, I won't arrange for you if you have something to do yourself."

"After buying the books, just go back to the boat by yourself."

"Anyway, the ship is now in a civilian port, and we can come and go as we please."

After all, Ren Yan looked at Zhang Ting with some embarrassment.

Zhang Ting immediately understood: "Then I will go with him."

"In Niu Pu's words, I can't be used here anyway."

"Although this kid can speak some basic expressions, his English level is still worrying. I can provide multiple protections."

After finishing speaking, Zhang Ting looked at Niu Pu with a smile: "How is it? Do you welcome Teacher Madam to follow you~"

Niu Pu blushed slightly: "Then thank you, Master."

"Okay, look at your strength, why should I thank my wife~" Zhang Ting replied with a smile again.

After saying goodbye to Ren Yan and others, he took Niu Pu and walked towards the door.

Only a group of Class [-] students were left looking at each other.

They heard just now that what their teacher said was that Niu Pu would not arrange tasks for him if he had something to do.

So, according to this phrasing
Most of them have new missions.
After staring at each other, the rest of the Class [-] students immediately put on a 'really so' expression and fixedly looked at Ren Yan.

"Teacher Ren, tell me~"

"What do you want us to do?"

After the words fell, Ren Yan didn't bother to show off, and said the mission she had thought up in the car:

"It's very simple, just let you complete a travel guide about Nandel."

"The premise is that you must complete it independently, and you must have your own experience."

"Including but not limited to gourmet food, attractions, amusement parks, entertainment centers, and even some customs or quiet trails that you think are good."

"For a period of time, half a month."

"In the past half month, you can treat yourself as tourists and browse the city with your heart. All consumption will be paid for by the class fee."

"In other words, it's eating, drinking and having fun at public expense, and then sorting out a set of fun experiences."

"How about it, are you confident?"

Hearing this, the students in Class Nine were stunned, with joy in their eyes, and asked tentatively:

"That is to say, during this period, we don't need to do anything other than have fun?"

"Of course~" Ren Yan nodded: "You can even experience the special hotels here. It's okay not to go back to the ship at night, but you must report in advance."

"And it's okay, you can't enter some places with age restrictions, otherwise don't blame your teacher for being rude."

As Ren Yan clenched her fist, there was a crunching sound.

Everyone in Class Nine was instantly chilled.

That small thought in my heart disappeared immediately.

Originally, they wanted to show their teachers how good they were here.

But now it seems that with my two actions, I am afraid that I still can't do it better than my teacher~
But even so, they are in a good mood now.

Play at public expense, and there are basically no restrictions.

I have been with my teacher for so long, when did they have this kind of treatment!

My teacher saw that it was enlightening!

Although they were a little worried and scared about Laurie's invitation, when it came to Ren Yan, they felt that this was one of the few bright moments of their teacher.

As for your own depravity?
Just kidding, spending your own class fee, how can it be considered depraved? !

This is all they earned with great difficulty!
At the same time, they are also very clear that this matter seems to be for fun, but there is a mission after all.

If they don't complete this task, they will definitely not be able to eat and walk around.

This is an insurance that is hidden by his teacher.

And in fact, it's pretty much the same.

The reason why Ren Yan decided to complete a travel guide was the task of Class Nine in the Stars and Stripes.

There are mainly two considerations.

The first point is to improve the English of everyone in Class Nine.

In the Stars and Stripes, if everyone in Class Nine wants to play well, they must use English at all times.

If you just wander around in Chinatown, then this travel guide is basically useless and has no reference value.

But in Chinatown, whether it is eating food or going to an amusement park, Class Nine needs to use English.

Not only can you speak, but you must also be able to write and recognize.

With a long time and a relaxed atmosphere, Class [-]'s English skills, both in speaking and in writing, will definitely improve a lot.

This method of learning while playing has long been tried and tested by Ren Yan.

Moreover, letting Class Nine play happily can also make them more active.

According to Ren Yan's understanding of the kids in Class Nine, they will definitely seize this opportunity to experience all kinds of things they have never seen or yearn for.

This back and forth, the learning effect is directly full.

As for the final strategy, it is even a summary of their play this time.

With this thing, Class Nine will not be too carried away with playing, and can even urge them to feel it with their hearts, so that their sense of experience will be greatly improved.

Simply a win-win!
And the second point was realized by Ren Yan when Class Nine rejected Laurie's invitation.

Class Nine has been with him for such a long time. Although he has developed a good habit of self-sufficiency, he seems to be a little uncomfortable with spending money to enjoy it.

This is fatal to the current Class Nine.

No matter what it is, whether it is good or bad, it is always too much.

Ren Yan didn't want Class Nine to go further and further on this self-sufficient road.

Self-sufficiency is the confidence in the face of crisis.

But it is also one of the joys of life to spend the money you earn to enjoy life.

What Ren Yan hopes is that the students in Class Nine can maintain a balance between the two, so that they can suffer and enjoy happiness.

Don't want them to slide to either extreme.

For example, this high school in Nandel may be the extreme of 'pleasure'
After their teacher had announced their task swearingly, everyone in Class Nine suddenly realized a problem.

Then, they turned their attention to the squad leader, Awei.

As the chief butler of Class Nine, Ah Wei, should feel distressed for this kind of fun activity that is completely paid for by the class fee. Don't deduct their activity funds at that time. If this is the case, then they will be very passive.

However, as soon as their eyes focused on Awei, Awei raised his neck in disdain:
"Tch, who do you look down upon~"

"Don't worry, the class fee is enough for this time!"

"My buddy is a person who has learned the new accounting method, and our class fee is more than enough!"

Speaking of which, Ah Wei deliberately revealed a look of disdain for the world.

However, when everyone in Class Nine wanted to cheer for Awei, Awei looked at everyone expectantly, and quietly added:
"and"

"What we are doing this time is a travel strategy."

"This thing is really made, can't it be regarded as a commodity of our ninth class?"

"So, everyone, you must try your best to make a perfect strategy~"

As soon as this remark came out, everyone in Class Nine was speechless, and curled their lips in unison: "Tch~~~"

Only Wang Bo's eyes lit up, and he remembered this in his heart.

Ah Wei is right, this thing, what a project~
but
Class [-] is getting lively here

The two hosts on the side scratched their heads in doubt.

"What are these Dragon Kingdom friends talking about?" Clare looked at Laurie.

Laurie shook his head: "Hen~"

In an instant, the other party rolled their eyes: "That's it, you have the nerve to say that you have been hanging out with them for a long time?"

"You don't even know what people say?!"

Hearing this, Laurie looked at Krell dissatisfied: "Nonsense!"

"As for how difficult Dragon Language is, don't you have a B number in mind?!"

After the words fell, the two sighed in unison.

Not far away, Wang Yu couldn't stand it anymore, and roughly translated the conversation in Class Nine just now.

He also incidentally shared some of his own views on this task.

When he finished translating all these.

The two of Laurie stood there in a daze for an instant, and looked at the teachers of these Class [-] students in disbelief.

His eyes were full of horror.

They couldn't figure out how the other's head grew.

When can travel strategy be played like this? !

Has this group of Long people learned foreign languages ​​to this level?
But it sounds like it makes sense.
Silently, the two looked at each other and had a bold idea in their hearts.
