Genius is just the threshold for me!

Time flies, spring goes and summer comes, and in the blink of an eye it's late April.

Although it is still early summer, the temperature has risen significantly, and people have taken off their spring fleece jackets and put on simple long-sleeved shirts and thin pants.

"Wait! Lin Dong, wait a minute..."

Saturday the 27th.

Because of make-up classes during the May Day holiday, Lin Dong and others are still in school.

After school in the afternoon, all the students in the classroom had left.

Just then, Xu Qingling, who had been called to the homeroom teacher's office for a while, returned. Suddenly, as if she had noticed something, she rushed to Lin Dong, who was waiting in the corridor, raised her fair right hand, and gestured above their heads. Immediately, she exclaimed with delight, "I think I'm taller than you now!"

"I'll give you six months."

Lin Dong looked at the girl who had grown significantly taller and started to surpass him after almost a year of junior high school, and whose chest was beginning to show more curves, and chuckled, "By the end of the year, you won't be able to beat me."

Whether it was because he influenced Xu Qingling's lifestyle and eating habits, although his height was a few centimeters taller than at this time in his previous life, he still grew rapidly for more than a year in the second semester of sixth grade and the first year of junior high school, and his height was still surpassed by hers.

"Hmph, I'm sure I can keep it up until the New Year."

Xu Qingling snorted and said confidently, "I will grow taller. My goal is 174 centimeters."

"come on."

Lin Dong offered a word of encouragement, smiling as he said, "Want to go to the lab together later? My mom wants you to come over for dinner tonight."

"OK."

Xu Qingling nodded generously: "Then I'll tell my mother later that I won't be going home for dinner tonight."

talking.

Xu Qingling ran over to Huang Qingyao, Su Yue, Jiang Caiping, and Xia Ran, and the group of girls started chatting excitedly.

Lin Dong glanced at Xu Qingling in the crowd, smiled, and looked away. He then joined Li Tao, Zhang Yihao, and the others to form another group and head home.

After the New Year, having grown a year older, perhaps due to the long-tail effect of Zhou Xiaoyan's metaphorical encouragement, or perhaps because Xu Ziming didn't give her as many cold looks, Xu Qingling was noticeably more confident about things concerning him.

Although I still cling to him and indulge him, I'm no longer as afraid of losing him as I was when I first entered puberty last year, and I wish I could be with him all the time.

I felt less anxious and worried, and more confident and composed.

"Wow, brothers and sisters!"

A group of people left the campus and walked to the vicinity of the camp.

At that moment, Li Tao, holding his phone, seemed to see something and exclaimed in disbelief and anger, "Our scientific research technology has been stolen by the Americans?"

"What kind of scientific research technology?"

Li Tao's call caused the girls who had been chatting noisily to stop and come over. Su Yue, in particular, asked curiously, "Are you from Chengdu Aircraft Industry Group?"

"Our hypersonic research and technology..."

Li Tao displayed information he had seen on a professional military forum, and said with some anger, "Last month, the Americans secretly started a hypersonic research program."

This research and development plan has now been finalized. It's the plan Zhang Zhong revealed during the last two days of winter break: to use an experimental aircraft and treat the sky as a wind tunnel.

The US has already used supercomputers and computational fluid dynamics to design a prototype fuselage for a hypersonic aircraft.

The next step is to prepare to produce 3,000 experimental aircraft to tackle hypersonic vehicle technology...

"Damn it! That traitor Zhang Zhong just casually leaked such crucial research and development technology!"

"This doesn't involve specific technical data, it's just a research and development idea, it should be quite simple."

Su Yue chimed in, "Even if we don't reveal it, the Americans will definitely figure it out."

"Research and development is all about ideas and direction; that's the most crucial thing. Without ideas and direction, no matter how skilled you are, it's useless."

Li Tao was still somewhat indignant: "That old man, why doesn't he get charged with treason! He's always badmouthing the country and selling intelligence!"

"..."

Lin Dong's lips twitched, and he exchanged a glance with Xu Qingling. Both of them relaxed and suppressed their smiles.

"This might be part of a national plan. It's hard to tell what's real and what's fake."

Xia Ran, standing next to Huang Qingyao, seemed to notice Lin Dong's expression and invited everyone, "We'll have an extra day of classes tomorrow, making it a three-day May Day holiday."

Everyone's coming to my house to play games and have lunch the day after tomorrow morning. My mom's on vacation then, so she doesn't have to go to work...

"Wow, Aunt He is cooking?"

Upon hearing this, Su Yue's eyes lit up, and she exclaimed in surprise, "Northeastern cuisine?"

"Yes."

Xia Ran nodded with a slight smile.

Since He Ying was transferred to the logistics department before the Lunar New Year and no longer participated in core research and development, Xia Ran also joined the activity of taking turns inviting her colleagues to visit.

It's been more than two months since the Lunar New Year, and this is the second time I've invited everyone to visit.

"No problem, we'll arrive on time!"

Su Yue was the first to nod in response.

"Can."

Lin Dong and Xu Qingling nodded.

Li Tao, Huang Qingyao, and Jiang Caiping also agreed.

The project is not yet fully completed, everyone is still under stay-at-home orders, and there have been espionage activities such as a family tracing operation.

So even if there's a three-day holiday for May Day, people will most likely stay home and not go out, so visiting someone's home is perfectly fine.

After confirming their visit to Xia Ran's house the day after tomorrow, the group chatted for a while before returning to their residential compound. Everyone else went home, while Lin Dong and Xu Qingling went to laboratory number 78...

Di-

Lin Dong entered the password and fingerprint to open the laboratory door. After the two went inside, the door closed automatically.

"Is your supercharged engine almost finished? Is that what Dad's been working overtime on these past few days?"

Once inside the laboratory, in a secure environment, Xu Qingling made no attempt to hide her feelings, looking at Lin Dong with sparkling eyes and asking him a question.

Although Lin Dong doesn't usually say it, she usually follows him to the lab whenever she sees him coming.

Once in the lab, she would do her homework or read, while Lin Dong would be busy with other things.

Because the two of them coming together can provide Lin Dong with some cover for his identity, preventing him from running to the laboratory alone all day, which would be too conspicuous and abrupt.

This is also the main reason why everyone in the community, and even among all the employees of Chengdu Aircraft Industry Group, knows about their arranged marriage.

But if Lin Dong calls her first, it usually means he has something to share with her. And the most recent thing is undoubtedly the super-burning engine that Lin Dong has been working on for more than a year.

"Don't guess next time."

Lin Dong flicked Xu Qingling's forehead, then smiled and said, "Uncle Jiao's technology on 624 is getting better and better, and the progress is quite fast. It was completed almost half a month ahead of schedule. The parts have been manufactured and are now in final assembly..."

Unlike the previous pre-cooled engine and variable cycle engine, all parts of this supercharged engine are manufactured in 624.

However, because Jiao You was older, his nerves were deteriorating and his hands were no longer precise, and his physical strength was also failing, the final assembly team transferred him to Chengdu Aircraft Industry Group and handed him over to Xu Ziming.

to this end.

Xu Ziming had to work overtime for three days to study the blueprints of the entire supercharged engine, and at the same time, he discussed and finalized the entire assembly process with Jiao You.

As Lin Dong spoke, he led Xu Qingling to the door that led to Xu Ziming's assembly workshop next door, but it was so small that it was impossible to see the door without getting close.

Pushing the door open forcefully, one sees four adults—Wang Xingguo, Su Ruohua, Jiao You, and Lin Weiliang—wearing dustproof suits, standing outside the cleanroom like guardian deities.

"Dad, godfather and godmother, Uncle Jiao..."

Lin Dong paused for a moment, then asked curiously, "Why are all four of you standing outside in your dust suits?"

"Ask this guy!"

Wang Xingguo pointed at Jiao You: "You get all excited just looking at an engine assembly... Your Uncle Xu thought we were in the way and kicked us out."

Although he was the chief engineer of Chengdu Aircraft Industry Group 001, he had no complaints about being ousted from his professional field and being inconvenienced. He could only blame the old man Jiao You.

"You don't know anything! This is a supercharged engine, do you even understand what a supercharged engine is?"

Jiao You retorted directly, "Judging from your calm demeanor, no wonder your engine expertise is only half-baked, like a PhD student who can't even understand the blueprints, right?"

"Unlike you, I haven't seen much of the world and I don't make such a fuss over such a small thing," Wang Xingguo replied calmly.

"Alright! Wang Xingguo, Teacher Jiao!"

At this moment, Su Ruohua came in and said irritably, "You two make way for Xiaodong and Qingling, don't block the windows. You're over fifty and still arguing like children..."

Lin Dong smiled and led Xu Qingling to the window to look inside.

In the cleanroom that had been cleaned a few days earlier, Xu Ziming's figure came into view, along with two small engines that had already been largely completed, each with a diameter of 400mm and a length of 2700mm.

Through the still-open outer shell, you can see the different air intakes inside, one of which corresponds to the familiar variable cycle engine.

On the other side is a flat, hollow structure, resembling a skateboard.

Through the hollow entrance, one can vaguely see a strangely shaped slope with beautiful curves.

There are no rotating parts such as fan blades visible inside; instead, pipes extending from the pre-cooling unit are connected to it...

This unique hollow skateboard structure is the super-powerful engine that Lin Dong has been researching and designing for over a year.
