Xueba: I study hard in the wasteland world

Time passed minute by minute, and after three full hours, Su Yu completed the derivation of an equation.

At this time, Su Yu's desk was covered with draft paper.

This calculation was very long and contained a lot of content. Su Yu had to concentrate on it carefully and attentively, because if there was an error in a symbol or operation, it would mean that the result would fall short and Su Yu would need to derive it again.

But fortunately, the results deduced step by step are all correct.

Su Yu felt full of accomplishment: It's really good. The books I read so hard and painstakingly in the wasteland world were not in vain!

…

It was already past 12 noon. Xia Ning, who was sitting next to Su Yu, completed the calculation of the final after-school questions and stretched out with great achievements.

And when she glanced at Su Yu sitting next to her, Xia Ning became anxious!

What is he counting? There are so many pieces of paper and you haven't finished counting yet?

Hey, I am still very successful in successfully answering the after-school questions, and Su Yu has started to deal with such complicated problems.

Before, Xia Ning could understand Su Yu's drafts no matter how hard she tried, but now she couldn't understand them at all no matter how hard she tried.

Xia Ning raised her head and looked at Su Yu.

Under the sun, serious Su Yu really shines.

This feeling made Xia Ning feel bad. She had always been the White Moonlight in the eyes of others since middle school, and now she was killed miserably by Su Yu, the White Moonlight!

Xia Ning felt that she must have a bad brain to have a crush on him!

Su Yu, who was completely immersed in the calculation, didn't even notice Xia Ning beside her. This long calculation required full concentration, and Su Yu didn't dare to distract her attention at all.

Whether the calculation is correct this time is very important to Su Yu.

Because this calculation will determine whether the company's derivation of the B2 stealth strategic bomber is correct, and also determine whether Su Yu can gain a foothold in the domestic aviation academic community.

Huh~

When Su Yu finished writing the last line of calculations, he breathed a sigh of relief.

The senses blocked by the brain returned. Su Yu took a sip of water and slumped in the chair - he was exhausted, exhausted, and hungry.

Thanks to running every day, his physical fitness is still good. Otherwise, Su Yu wouldn't be able to stand it at all!

Huh? Where's Xia Ning?

Looking at the empty seats next to him, Su Yu was stunned. He remembered that Xia Ning was sitting with him. Where had this little girl gone?

You're not going to fall in love, are you?

Su Yu whispered to herself, Recently, there was a handsome guy from the city's music college who was chasing Xia Ning crazily.

This handsome young man drove a Porsche sports car from the city to Western Polytechnic University in the wilderness every day to deliver gifts to Xia Ning.

This made Su Yu feel a little weird.

Ignore her!

Su Yu shook her head, how could a woman study?

Turning on her phone and looking at the time, Su Yu jumped up: Holy crap! It's already half past two in the afternoon! There are still classes in the afternoon!

Su Yu hurriedly started to pack her things and prepare to go to class.

Huh?

Just as Su Yu was putting away the scratch paper, he was suddenly attracted by a line of calculations that he had crossed out on the scratch paper.

It doesn't seem right?

She forgot that she had to go to class, and that it was already half past two in the afternoon. She hadn't even eaten. Like a scavenger digging for treasures in the ruins, Su Yu hurriedly sat down and started to read from the dozens of pages of draft paper she had written. Pulling.

At this!

When Su Yu pulled out a derivation of the solution to the vectorization of the NS equation, she was delighted. She hurriedly took out a red pen from her pencil case and began to draw circles on two pieces of draft paper seriously!

After a few minutes of intense sorting, Su Yu, who was serious and solemn, picked up a blank piece of draft paper and re-wrote a line of calculations with a red pen.

Then, Su Yu excitedly took out her computer, opened the web page, logged in to her account, and began to search for data in the database of 278.

But soon, Su Yu frowned, her excitement was gone, and she looked as unhappy as constipation.

Ah! How could it be wrong!

Su Yu put his hands in his hair and scratched his head. It stands to reason that the model he derived is correct, and there should be no data mismatch!

But it appears now.

The B2 stealth strategic bomber of this weak country is the same as an alien black technology, and many top-secret components do not have any reference data at all, so Su Yu can only rely on hard deductions, which is a difficult job!

Judging from Su Yu's solution, the NS equation is a good derivation idea.

▽ represents the gradient, which is the vector in the direction of the maximum increment of the constant function. Using this to analyze the three dimensions, this path should be feasible!

After a brief inspection, Su Yu muttered to himself depressedly and twisted his head. He felt a little headache!

Shouldn't it?

Did I make a mistake in my calculations?

Inspiration comes quickly and leaves even faster!

Su Yu looked at the dozens of pages of thick draft.

Su Yu wanted to die if she wanted to check step by step whether there were any mistakes in calculation!

After re-derivating and checking, Su Yu wanted to die even more!

This B2 stealth strategic bomber is indeed a black technology that stands at the top of the human technology tree!

How did those engineers who worked for decades create this aircraft?

Awesome!

Su Yu couldn't help but praise the enemy in her heart.

Su Yu was deducing with the knowledge of aviation in the wasteland world, but still had no idea.

Of course, Su Yu is deriving data for the B2 stealth bomber. It is not that China wants to directly copycat the B2, but to derive relevant performance parameters to provide reference for China's own stealth strategic bomber.

Now even if the United States has complete drawings, they will not be able to restart the production line and produce B2 again.

The current weak country of the United States looks very powerful and scary, ranking first in the world militarily and first in the economy.

In fact, if you look closely, it is not much different from the Qing government in the late Qing Dynasty.

The Qing government at that time was not only a behemoth, but also the world's largest economy;

Although the military is not number one in the world, it is number one in Asia. It looks like a tiger.

That daring little Japanese pirate poked him and he was defeated!

Are you depressed?

Seeing Su Yu leaning on the chair in a daze, Xia Ning, who was standing next to Su Yu, asked.

Hmph, are you back in love?

Su Yu, who woke up from deep thought, saw that it was Xia Ning and directly snarled.

Whoops, someone's got a gunshot!

After being scolded by Su Yu, Xia Ning was not only not angry, but also very happy.

After an afternoon of classes, Su Yu didn't come, so Xia Ning knew that he must still be in the library, and that he probably hadn't eaten all day.

Xia Ning placed a beautifully packaged dessert bag in front of Su Yu and said, I can see at a glance that you haven't eaten, so I'll give you a small piece of cake to cushion your stomach.

Su Yu, you are so awesome, you have actually been sitting in this library all day!

Outside the reading room, Xia Ning, who was eating cake with Su Yu, opened her mouth to praise.

That's right! Su Yu nodded proudly.

It feels great to be praised by others, especially by Xia Ning.

Su Yu, who was originally in a depressed mood, was praised by Xia Ning, like a big rooster seeking mate, with its tail raised very high.
