As the plane took off, the couple's status was also temporarily suspended.

Love without learning is a vain castle in the air, which will be extinguished at the touch of a touch.

Li Zheng's aerospace heart was already received yesterday.

Now, too, it's time to take a breath of silence.

At the same time as Lin Yujing fried Mao Complement Competition, Li Zheng closed his eyes.

Started working on engineering.

The quest system, which had been left out in the cold for too long, was immediately activated from hibernation.

[Practitioner mission completed.] 】

[Earn the title - Old Engineer.] 】

[Veteran engineer: You can simulate complex experiments and engineering designs in your mind, and be more keen to find the weak links and optimization ideas. 】

At this moment, Li Zheng is not alone.

The soul of the old programmer and the old engineer is one.

[Chemical Meditation] and [Mathematical Brain] teleportation induction.

The real simulation of the mind, the embodiment appeared.

It was as if an engineering software had been opened in his mind, and the YF-88 engine structure, which he had just participated in, appeared in the center of the field of vision.

In this thinking simulation, Li Zheng can not only zoom in on the details, but also simulate the state of trial operation, but set the required parameters in his thinking.

Li Zheng tried to restore the limit speed of the oxygen pump at 13,500rPM (13,500 rpm), and the engine was running normally.

He tried to speed up the time multiplier, and after 870 seconds of continuous operation, the turbine began to vibrate erratically, until it broke and broke at 940 seconds.

This is naturally far beyond the maximum running time, and in reality, except for SpaceI's boss Mast, no one will be so idle to blow up the engine.

But now Li Zheng can too.

He tried to accelerate to 14,000 rPM, and this time the break was 740 seconds earlier.

Hey, that's fun!

For the third time, he directly increased the rotational speed to the theoretical limit of the design, which is 35,000 rPM.

Unexpectedly, the pump lasted half a minute before exploding!

In this mental simulation, he can also make material substitutions, all the materials that he has personally touched and know the parameters can be simulated. Unfortunately, apart from Huang Er, he has little experience in a series of special alloys for heavy industry, and can only replace them with ordinary steel that he has been exposed to before, and of course, he can also replace them with plastic and even wood.

Wood is the most fun, as soon as it is activated, the core parts turn into a pile of wood chips in the blink of an eye, and there is no chance of exploding.

As for steel, in fact......

It can really be made into a rocket!

It's just that the pressure and temperature it can withstand are relatively limited, and it is difficult to meet the requirements of hydrogen and oxygen engines, while as for solid fuel engines, it can be achieved in theory.

In the face of this engineering simulation world, Li Zheng is like a child who has discovered a new toy, and like a young man who opens some very exciting websites for the first time, playing crazy and without restraint.

It's like a small world of engineering and a thinking lab.

His play also makes the world more and more abundant, the structures he imagines will be stored in the form of design drawings, and the used materials and experimental reagents can also be easily accessed at any time.

When he was woken up by the flight attendant, there was only one regret left in his mind -

Uranium-235!

I really want uranium-235!

Gotta get some of this.

I want to experience the nuclear level!

The flight attendant only thought he was having a nightmare, and immediately laughed: "The plane is about to land, please adjust the back of the seat." ”

"Oh, oh......" Li Zheng had to temporarily put down his ambition and press the knob to return to his original position.

"Ma'am. The flight attendant then turned to Lin Yujing, who was frantically answering the question, "Please also trouble you to put away the small table." ”

"Hmm......" Lin Yujing blew up the book on scratch paper, which was the kind of embarrassment that Li Zheng liked very much.

"Ma'am?"

Lin Yujing gritted her teeth, and had no choice but to close the table with a "bang", and then stick to the back of the seat in front of her, leaning over to answer the question in a hideous posture.

The flight attendant had never seen this kind of person, so he swallowed and foamed at the mouth and asked, "Yes...... Is it a very important assignment...... It may be dangerous for you to do this, or is it advisable to sit up straight......"

Lin Yujing pouted and struggled: "Sister, can you leave me a way to live......"

"Alright then......"

The flight attendant had no choice but to leave.

Li Zheng rubbed his eyes, squinted his eyes and smiled: "I can study in my dreams now, are you afraid?"

Lin Yujing ignored him at all, and he was about to stand up with the force he needed to answer the question.

Soon, the radio came, and the plane began to descend.

Lin Yujing also became frizzy instantly.

The stage she feared the most appeared.

When taking off and landing, due to the change in air pressure......

Tinnitus can occur!

Specifically, the tympanic membrane is convex or inverted.

There will be a feeling that the ears are about to be sucked or squirted out, which is just uncomfortable for normal people, but for groups like Lin Yujing, whose ears are too sensitive, it is equivalent to stabbing the ears frantically with a hairy stem.

She usually takes a series of measures such as covering her ears and swallowing frantically to relieve the pain caused by this process.

But now, her hand is going to answer the question according to the paper!

"Hmm—-—-"

A trilled "hmm" appeared, which meant that she had felt the teasing of the hairy pole.

Lin Yujing struggled with tears.

Even Li Zheng was a little distressed.

"If you think about it, my super-speed vacuum can also run in reverse. Li Zheng licked his lips and leaned over, "I can inject a steady stream of breath into you, and use my lung capacity to fill your air pressure difference." ”

"Hmm—-—-" Lin Yujing shook her head desperately while shedding tears while doing the question.

"It's okay. Li Zheng's face was full of determination, his brows were tightened, and he got closer and closer, "I will bear double the air pressure difference, but as long as you can be well, what is this pain?"

At the moment when the lips are about to be attached.

Lin Yujing slapped the roll on Li Zheng's face: "!! handing over the volume"

Then he covered his ears and shrunk by the window.

Li Zheng took off the roll and wiped his mouth unwillingly: "Aren't you very moved when I'm usually like this?"

"Don't dare to move, don't dare to move......"

Li Zheng shook his head and began to read the papers in a boring manner.

From take-off to the present, it took an hour and a half to count.

Of the four major questions, Lin Yujing completed three and a half questions, which is already a very good result.

Let's look at the process again.

Alas......

It's beyond the standard answer again.

Li Zheng can only follow her train of thought to prove it, as long as she can't find the problem, it's right.

With the help of accelerated thinking, the plane stopped and the passengers got up, and Li Zheng was finished.

"147 out of 180. Li Zheng handed the paper back to Lin Yujing, "Considering your mental state, this is an excellent result, and the official exam is at least the top five in Jijing." ”

"Top five......" Lin Yujing pulled the roll, rubbed her ears and trembled, "I remember...... You're the second ......."

"Yes, that's nine points higher than you. Li Zheng said and took out his mobile phone, "To be honest, if you have plenty of time and status, you should be better than me in the test." ”

"So......" Lin Yujing grabbed Li Zheng's arm and shook it, "It's a draw~~~~"

"Sorry, it's a matter of principle. Li Zheng showed his Taobao, "I placed an order for these things." ”

Lin Yujing stared at the goods above, opened her mouth, and was speechless: "Whew......"

"What's the matter, do you have it?" asked Li Zheng.

Lin Yujing looked at Li Zheng stupidly, and shook her head again and again: "Hmm......mm"

"Then is this model okay?" Li Zheng looked at his phone and said, "I asked Wu Shu to ask someone from the Department of Astronomy to choose it." ”

"Uh-huh. Lin Yujing blinked again and nodded.

"Then buy it!" Li Zheng finally made up his mind to press the purchase, "Next week's theme is astronomical observations, but I'm going to be on it." Anyway, I've always wanted to see it with my own eyes, Saturn, Jupiter, Mars, and ......."

"And the sun, nebula, and three-body star!!" Lin Yujing said and leaned on Li Zheng's shoulder, and rubbed it, "You said wow, I would have admitted defeat if you said it earlier." ”

Li Zheng's arms stiffened and trembled.

It's the first time he's been labeled like this......

Although Wangcai is occasionally in a good mood, it will be like this......

But this soft pedaling feels slimy......

Li Zheng smiled stupidly and leaned back on the back of the chair satisfactorily.

"Sir...... The lady ...... "The flight attendant has been standing next to him for a long time, and at this moment he finally couldn't bear it anymore, and gritted his teeth with his head behind his back and said, "Almost...... It's time to go......"

That's the way it is.

Just as in the conservation of energy, nuclear bombs can be made by relying on mass-energy conversion.

In the conservation of happiness, a couple in love is the most terrifying nuclear weapon.

......

The 35th National Middle School Mathematics Finals had actually been registered the day before.

Early in the morning, the members of the Jijing team who had breakfast had gathered in the hall, and they needed to take a bus to the First High School of China Normal University before 8 o'clock to attend the opening ceremony.

It is worth mentioning that the number of the provincial team this time is far larger than that of other disciplines in Jijing.

The size of a regional provincial team is determined by its past results, and the better the results, the more places will be awarded.

Thus, just from the scale, it is possible to see the place of a province in the race.

Everything is back to the origin of who has more people and who is awesome.

Within 5 people - obscure province.

5-10 people - a small famous province.

10-15 people - a little bit of a province.

15-20 people - bigwigs gather in the province.

More than 20 people - the capital province of the giants.

In other discipline competitions, the number of Jijing provincial teams is usually between 10-15, excluding Li Zheng's mutation, and then excluding Lin Yujing, a monster who has been holding back for I don't know how many years, the average strength of the Jijing team belongs to a little thing, and occasionally there is a big guy, but compared with giant provinces like Xiangnan, there is still a level gap.

But the math is different.

This year, there are 21 members of the Jijing team, which is a well-deserved giant-level team.

Why is this happening?

There is only one reason.

Renda Affiliated ...... I'm quite serious about math.

In other disciplines, Renda has grasped it over the years, but it has not made absolute all-out efforts, and it can even be said that the school does not want to grasp it subjectively, but it is forced by the needs of many students who want to rely on various competitions to add points to the college entrance examination.

But math, they've traditionally been focused on, and they do have some of the most gifted students in the city.

Therefore, unlike other subject competitions, the situation of the Municipal No. 1 Middle School and the Renda Affiliated Division did not appear.

In the 21-member provincial team squad, Renda occupied 13 seats and was crushed.

Naturally, the leader of the team this time is naturally Zhou Mingyang, a mathematics teacher attached to Renda.

is different from Yang Changle's giggling teacher, he looks much more serious, wearing square silver-rimmed glasses, and always has a straight face, so that his classmates only dare to sit on the sofa and wait silently, not daring to be too arrogant.

Waiting and waiting, a tall boy trotted over: "Teacher Zhou...... Gui Mi Feng said he was not feeling well, and the opening ceremony was ......"

"Got it. Zhou Mingyang raised his hand and said, "You stay and take care of him." ”

"I said come on, and he said no, just lie down by yourself. ”

"That's all there is to it. Zhou Mingyang looked around and said, "It's almost, you name it." ”

"Except for Gui Jianfeng and Li Zheng, 19 team members are here. The boy looked up and swept around, "Teacher Zhou, can Li Zheng come?"

"He said it was today. Zhou Mingyang shook his head and said, "Then the aerospace group asked us to cooperate, what can we say? He's really amazing, I've never seen such a big player in all my years of competition. ”

The more Zhou Mingyang spoke, the more angry he became, so he raised his hand and counted down with the teacher next to him: "I didn't come to the training camp, and I didn't come to the opening ceremony, our school's Xiao Deng last year was good enough, he won the IMO championship, and he also won the international gold medal in the information competition, is he like this?"

The female teacher of the fourth middle school next to her hurriedly persuaded: "Li Zheng also has a task, didn't you watch Huang Er's live broadcast yesterday?"

"I saw it, why didn't I see it, our competition class was suspended to watch. Zhou Mingyang became even more angry when he chatted, "What a serious thing aerospace is, how much effort has been condensed, and he ...... By his last slap ...... What a system this is!"

"I think it's pretty good...... "On the other side, the young male teacher attached to the Normal University smiled, "Do you know how many people have been touched by this scene, and many people are determined to be aerospace because of this." ”

"When does aerospace need to rely on this to attract people?" Zhou Ming raised his eyes, his glasses were crooked, "The co-authors are all for the purpose of engaging in objects?" Yes, I admit that the young female engineer...... That's really beautiful...... Can ......"

As he was talking, a man suddenly shouted.

"!!!

Suddenly, the entire hall fell silent.

Not only the Jijing team, but also the children of other provincial teams also got up and looked at the gate of the hotel at the same time.

Yes, it was him, he appeared.

He walked in silence.

He is not angry.

They cling, hugging, chatting about the shape of Saturn and then they come in!

And still.

It's also a legendary existence.

That one can always win, always be on top.

It was attached to Li Zheng's shoulder like a little daughter-in-law, as if it had been completely glued.

At this moment, the mass-energy equation of happy conservation explodes in an instant.

Happiness = Tranquility??

Quiet??.

Who can withstand this?

All of a sudden, an undifferentiated wave of happiness swept over every inch-headed man.

What do I want this math to do?

What if I have this IQ?

This moment.

Li Zheng has already won.

"Cheng ...... Cheng Cheng ......" Zhou Ming stared at the two from afar, his glasses sliding down more and more, "Cheng He...... He He ......"

At this time, Li Zheng also stopped, and he found that everyone was looking at him.

Lin Yujing was also so frightened that she didn't stick to it, straightened up, and pulled away the hand that Li Zheng was holding.

Call......

Everyone finally took a breath.

But immediately after, the hands of the two were intertwined with ten fingers.

Can't get by......

I couldn't breathe anymore......

At this moment, a little girl suddenly jumped up from the crowd: "This way!

Li Zheng's eyes widened, isn't this Lin Xiangye, it's really not embarrassing for our Dragon Ball group.

Lin Yujing also narrowed her eyes: "Which scumbag is this?"

"Just last time, Lin Xiangye of the biology competition. Li Zheng walked over with a smile, waved his hand from afar, and said, "The earliest flight can be regarded as catching up." ”

Lin Xiangye also stepped forward, and after saying hello to Li Zheng, he immediately grabbed Lin Yujing's hand: "Wow! Jingshen is even cuter than in the photo!"

"Hmm......" Lin Yujing turned her head shyly, "Which one...... Photo ......"

"It's not like Kiss~, anyway. ”

"......," Lin Yujing said in a trembling voice, "You kid...... Very good at talking......"

"Haha, Kiss is also good-looking. Lin Xiangye said as he spoke, saw the bus coming from outside the door, and hurriedly let go of Lin Yujing's hand, "I'm sorry...... We're going to the opening ceremony, I'll introduce Zhengshen to the teacher first......"

"Hmm......" Lin Yujing immediately waved her hand at Li Zheng, "I'll go through the formalities myself, and you can return to the team." ”

"Then you get some sleep first, and I'll try to come back early. ”

"Well, you also slept well at the opening ceremony. ”

After that, the two parted ways, and Li Zheng came to the three team leaders under the indescribable complicated gaze of everyone.

Zhou Mingyang was still in a trill: "He He He ...... Body ......"

"Okay, okay, Teacher Zhou......" The female teacher of the fourth middle school hurriedly stepped forward and smiled, "How about it, Li Zheng, this is going to the opening ceremony, do you need to take a break?"

"No, no, no. After Li Zheng bowed, he looked around, "What about Xiao Guigui?"

"Gui Jian Feng is not feeling well, resting. The tall boy looked at Li Zheng and swallowed and foamed, "Why do you have a nickname...... He doesn't come to school very much, and we don't know each other that well. ”

"Hey, competitions come across a lot. Li Zheng asked with a worried face, "Isn't it good to be sick at this time, do you need someone to take care of you?"

"He seemed to like to be alone and wouldn't let me in. The boy hesitated, "If you know him that well...... Why don't you stay?"

"I can. Li Zheng nodded again and again.

"That ......," the boy turned to the three teachers.

Two of the teachers turned to Zhou Mingyang.

Zhou Mingyang stared at Li Zheng for seven or eight seconds before he finally held it back: "...... Physique!!"

"......" Li Zheng's eyebrows tightened, is this playing with word solitaire?

The boy hurriedly introduced: "This is the general team leader, our teacher Zhou Mingyang attached to Renda." ”

"Hello Mr. Zhou. Li Zheng hurriedly said hello.

"You...... You ......" Zhou Mingyang pointed at Li Zheng with a sinister look, "she ...... She ......"

Before he could hold back his words, a figure suddenly jumped over.

"Excuse me...... I'm sorry teacher......" Lin Yujing leaned over to Li Zheng's side, timidly stretched out her right hand, "ID card ......"

"Oh, by the way......" Li Zheng quickly took out her ID card and patted it, "I forgot to give you ...... after boarding the plane"

"Huh......" Lin Yujing hurriedly bowed to the three teachers again, "I'm sorry, I'm sorry......"

Then he twisted his face and staggered away.

When the others were still dumbfounded and didn't have time to speak—

She ...... She ......" Zhou Mingyang stared again and held back for a long time, and finally sat down on the sofa, "She's so good-looking!!"

“......”

The character design collapsed like this, and the collapse was caught off guard.
