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

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

Li Zheng's ambition to aerospace was put away yesterday.

And now, it’s time to absorb some calmness.

While Lin Yujing was making up the numbers, Li Zheng closed his eyes.

Start working on the project.

The task system that had been left out for too long was immediately activated from hibernation.

【Practitioner task completed.】

[Get the title——Old Engineer.]

[Old Engineer: Can simulate complex experiments and engineering designs in his mind, and more keenly find weak links and optimization ideas. 】

At this moment, Li Zheng was no longer alone.

[Old Programmer] and [Old Engineer] souls become one.

[Chemical Meditation] and [Mathematical Brain] Telepathy.

Real thinking simulation appears in reality.

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

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

Li Zheng tried to restore the oxygen pump's limit speed of 13500rPM (13500 revolutions per minute), and the engine ran normally.

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

This is naturally far beyond the maximum running time. In reality, no one except Master, the boss of SpaceI, would be so idle blowing up the engine.

But now Li Zheng can do it too.

He tried to accelerate to 14000rPM, and this time the rupture was advanced to 740 seconds.

Hey, this is fun!

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

Unexpectedly, the pump took half a minute to explode!

In this set of mental simulations, he can also replace materials. All materials that he has personally come into contact with and knows the parameters can be simulated. Unfortunately, except for Huang Er, he has little experience in a series of special alloys for heavy industry and can only

Replace it with the ordinary steel that you have come into contact with before. Of course, you can also replace it with plastic or even wood.

Wood is the most fun. As soon as it is started, the core components turn into a pile of sawdust in an instant, without even a chance of exploding.

As for steel, actually...

It really can be made into a rocket!

However, the pressure and temperature it can withstand are relatively limited, making it difficult to meet the requirements of a hydrogen-oxygen engine. As for a solid fuel engine, it is theoretically possible.

Facing this engineering simulation world, Li Zheng was like a child who discovered a new toy, or like a young man who opened some exciting websites for the first time, playing wildly and without restraint.

This is both like a small engineering world and a thinking laboratory.

His play has also made the world more and more full of data. The structures he has imagined will be stored in the form of design drawings, and the used materials and experimental reagents can be easily picked up 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!

You have to do something like this.

Nucleoping! I want to experience Nucleoping!

The flight attendant thought he was having a nightmare and immediately said with a smile: "The plane is about to land, please adjust the back of your seat."

"Oh oh oh..." Li Zheng had no choice but to temporarily put aside his ambition and press the knob to return it to its original position.

"Ma'am." The flight attendant then turned to Lin Yujing, who was answering questions frantically, "Please put away the tray table."

"Well..." Lin Yujing wrote on the draft paper, in the kind of embarrassing state that Li Zheng liked very much.

"Miss?"

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

The flight attendant had never seen such a person before. He swallowed and asked, "Is it... a very important assignment... It may be dangerous for you to do this, so I suggest you sit upright..."

Lin Yujing pouted and struggled: "Sister, please leave me a way to survive..."

"Oh well……"

The flight attendant reluctantly left.

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

Lin Yujing ignored him at all and answered the questions so hard that she almost stood up.

Soon, a broadcast came and the plane began to descend.

Lin Yujing also became irritated instantly.

The stage she was most afraid of appeared.

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

It will cause tinnitus!

Specifically, it means that the tympanic membrane is bulging or invading.

There will be a feeling that the ears are about to be sucked or sprayed out. This feeling is just uncomfortable for normal people, but for people with overly sensitive ears like Lin Yujing, it is equivalent to poking the ears crazily with a hair pole.

.

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

But now, she has to press her hand on the paper to answer the questions!

"Well----"

The "um" sound accompanied by a vibrato appeared, which meant that she had felt the teasing of the hair rod.

Lin Yujing struggled with tears.

Even Li Zheng felt a little distressed.

"If you think about it carefully, my super-speed vacuum can also operate in reverse." Li Zheng licked his lips and leaned over, "I can continuously inject breath into you and use my lung capacity to fill your air pressure.

Difference."

"Uh---" Lin Yujing shed tears while doing the questions and shook her head desperately.

"It doesn't matter." Li Zheng's face was determined, his brows furrowed, and he got closer and closer, "I will bear double the pressure difference, but as long as you can be fine, this little pain is nothing."

The moment the lips are about to touch.

Lin Yujing slapped the paper on Li Zheng's face: "Hand in the paper!!!"

Then he covered his ears and huddled by the window, snoring.

Li Zheng took off the paper and wiped his mouth reluctantly: "Wouldn't you be very touched if I usually do this?"

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

Li Zheng shook his head and began to grade the papers indifferently.

From takeoff to now, it takes exactly one and a half hours.

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

Let’s look at the process again.

well……

It goes beyond the standard answer again.

Li Zheng could only follow her thoughts and calculate the proof. As long as he couldn't find the problem, he was right.

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

"147 points, the full score is 180." Li Zheng handed the paper back to Lin Yujing, "Considering your mental state, this is an excellent score, and it will be at least the top five in Jijing in the official examination."

"Top five..." Lin Yujing took out the paper, rubbed her ears and shivered, "I remember... you are second..."

"Yes, it's only nine points higher than you." Li Zheng said, taking out his mobile phone, "To be honest, given you enough time and state, you should do better than me."

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

"Sorry, this is a matter of principle." Li Zheng showed his Taobao, "I have placed an order for these things."

Lin Yujing stared at the products on it, opened her mouth, and was speechless: "Ouch..."

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