Chapter 381 New mission of Class 9, travel guide [6300, please book all]

"There is something wrong with the material?"

Upon hearing this, Krell immediately pulled himself out of his worries and asked back at the student of Long Country not far away.

"Yes, there is something wrong with the material." Xu Kai nodded and continued: "In my opinion, your workmanship is fine."

"The reason why the airbag cannot rush is simply because you have too much material in the airbag."

“My advice is that you should remove two more layers.”

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

"You have to know how difficult it is to find an airbag that looks one with the same color as the lining."

Upon hearing this, Crael shook his head without comment, preparing to continue to study the improvement plan.

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

"Now you can't even achieve the most basic use smoothly. Do you still care about the beauty?"

"Do you make this thing for use or for beauty?"

As soon as this said, Krell paused for a moment.

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

yes

The things you make are mainly used. Is beauty really that important?

"But 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 in three or two steps, staring at the other party with a burning gaze.

Although he still doesn't know what this Long Man is from.

But there would be no problem for those who brought Laurie.

And the other party seems to have a real trick?

He used all his efforts to do this surfing suit, and it would be better to improve it now.

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

"This and beauty can indeed be combined, but the design of your surf suit may be completely overturned."

"The design of your surf suit is too slim and the airbag is completely close to your chest. Once the materials are not up to standard, it will indeed cause unnecessary danger."

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

"So to solve this problem, I suggest you change the airbag in another position."

"Change the position?" Hearing this, Krell hesitated for a moment: "Where may you change?"

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

"You said that's a life jacket."

"But what you are doing now is a surfing suit, which is not the same concept at all?"

After begging his master's wife to translate Crael's words for him, Xu Kai struggled to answer in English again.

He found that his English level seemed to have reached its limit.

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

Too small vocabulary.

Seeing Xu Kai's entangled appearance, Zhang Ting was fortunate to act as the translator of the two again.

"Then where do you think is suitable?" Creer asked.

"Abdomen." Xu Kai replied seriously: "The abdomen is not only located in the body, but also has much larger space than the chest cavity. After all, the abdomen does not have hard bones."

"But can the abdomen really make people float up perfectly?" Crael still seemed a little hesitant at this time.

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

This thing is a carry-on airbag, but not a swimming ring, and there is not that much space.

Can the buoyancy of the abdomen really make people fall into the sea safe?

Crael couldn't believe it.

Seeing this, Xu Kai was too lazy to talk nonsense, so he asked Laurie directly for paper and pen. After finding a place, he started his own drawing work.

In a short while, a human body diagram was drawn by Xu Kai.

Although we cannot draw the scroll according to our own feelings like Zheng Chen.

But as the deputy chief designer of Class 9.

When drawing some objects that can be seen everywhere, Xu Kai is now a man of Men Qing.

After drawing, Xu Kai immediately started to perform calculations on it.

Calculate the buoyancy generated by carbon dioxide from the buoyancy required for the standard weight of the human body.

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

For this reason, he also assumed a lot of variables.

Finally came up with an answer:

"You see, through ergonomics, the airbags around the waist can also play the same buoyancy and will not cause deviations to the body."

"Although the effect may be a little worse, these can be corrected by the material."

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

"And in the future, you can also make airbags with different buoyancy according to different body shapes. As long as you choose the airbag that is most suitable for your weight, 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, listening to Zhang Ting's instant translation.

Crael's mind was full of question marks.

He pointed to the picture and pointed at Xu Kai, and said a word for a long time.

Finally, he had to look at Laurie and spoke in a daze:

"Laury, can you be sure we are not dreaming now?"

Hearing this, Laurie raised his brows, came to Krell a few steps, raised his right leg and kicked the other party.

He has wanted to kick this foot for a long time.

Now that the other party has given him a chance, Laurie did not 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 have dreams?"

"Now that you can feel the pain, it means you are not dreaming."

"Is there any problem with me doing this?"

Upon hearing this, Crael glared at Laurie: "I can see that you are taking personal revenge!"

Laurie nodded seriously.

Seeing this, Crael sighed silently, then looked back at Xu Kai and trembled:

"Then the question is."

"Where did you find these freaks?"

"How long has it been, this Long Man actually completed a complete set of comprehensive questions and used this comprehensive question to solve a problem."

“Can our practical teachers do this?!”

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

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

After confirming that he was not dreaming, Crael dragged out his questions in a row.

In fact, the moment Xu Kai completed the calculation, he began to doubt his life.

The Long Man in front of him looks about the same age as him.

But he easily did things he could not do.

All these signs are telling one thing. If this person from Long Country is nothing unexpected, he will be his fucking superman!

So, at that moment, Krell was confused.

The world has been questioned for the first time in history.

What I received was aristocratic education, but when did the Long Kingdom also have aristocratic education?!

Seeing this, Laurie curled his lips in Class 9, with disdain on his face:
