A nation's industrial development begins with junior engineers.

"This tastes wrong, Lao Huang."

"Look at the ideas behind the space reservation and pipeline routing. Aren't they about 70% similar to Scheme B, which we derived in our third revision to accommodate that 'precious model'? But in the details, they're... more radical, or rather, more idealistic?"

Professor Xu Hua adjusted his non-prescription glasses, his eyes narrowing behind the lenses as he carefully compared the details: "It's not just here. Look at the transition curve he drew between the sail and the hull; it clearly takes into account fluid separation noise control at higher speeds. We've made compromises on this at the current stage because we prioritize low-speed stealth. And the angle of the guide vanes at the pump inlet..."

"His drawings look like he looked at our preliminary draft and then made some... adjustments?"

Yes, these two, as the heads of the core overall group and the power group of the first generation of underwater nuclear black fish, did have a highly confidential initial design framework in hand. It was a blueprint that combined all the intelligence that could be obtained at present and the limits of existing domestic technology, and was repeatedly deduced.

Especially that one-meter-long submarine toy, the "treasure model" that Teacher Shi Lu mentioned above refers to this thing!

"This kid...where did he see our manuscript?" Teacher Shi Lu's expression turned serious.

Hmph! You unfilial son! Even if you are the son of my half-brother, when it comes to this kind of issue, I will still put aside family ties for the greater good!

Um... I wonder if it's too late to send him to that electrical engineering conference now!

While Mr. Lu, the hypocrite, was plotting how to rescue this dim-witted kid, Mr. Xuhua shook his head.

“Is it possible that…it wasn’t that he saw our manuscript, but rather…someone above took our manuscript and showed it to him?” He pointed to the sky.

"And then this kid, in his way, gave some... 'feedback'?"

Eh?

That's it...

Mr. Lu, who was so concerned that he lost his composure, also realized what was going on.

That's right, this kid has someone with him every step of the way. If he had any disloyal intentions, he would have been dragged away by the older folks for a moral education class long ago...

“So, he wasn’t showing off how clever he is,” Teacher Shi Lu stroked his chin, a mix of sudden realization and amusement. “He was saying to us, ‘Comrades, here, here, and here, I think we could discuss this further? Or perhaps, we could be a little bolder?’”

This is a perfect example of a lucky accident.

If Jiang Xia were awake, he would probably cry foul: I really just jotted down a few "directional" things based on some publicly available and relatively reliable concepts from the second-generation attack nuclear submarines that I remembered, combined with the relatively reliable basic theories from the Hayashio-class!

Who knew that in your timeline, nuclear submarine research had already secretly progressed to this stage? And you even managed to overlap so drastically with my "sketch version"?

Eh……

Is this all due to that silly kid's frantic flapping of butterfly wings?

Hmm, the shameless little rascal rolled over on the hard bed, and drool finally dripped from the corner of his mouth...

"Shh, keep your voice down. Don't disturb him!" Teacher Shi Lu tucked the blanket back over Jiang Xia, who was kicking it off. "Come on, let's talk outside!"

"Hey? That kid's little tagalong!" Teacher Shi Lu suddenly remembered something and looked around.

"He seemed to disappear when you called me. What, do you need to see him?" Teacher Xuhua was being pulled outside by him, but her head was buried in the drawings, and she didn't look up.

"It's nothing, just a casual question." Teacher Shi Lu waved his hand, his mind quickly returning to the blueprints, and pulled Teacher Xu Hua along as they continued their discussion.

"Hey? Look here, the transition curve in the middle section of the hull. Our design had a slight bend here to accommodate the existing pressure hull manufacturing process, but his drawings... smoothed it out, making the transition smoother."

"Could it be that this kid has figured out something new from the technology of the Hayashio-class submarines?"

"The inlet shape of the pump's flow channel, the angle of the diffuser section he drew, is even more aggressive than our calculated optimized value. Theoretically, it results in less resistance, but it also places higher demands on material strength and machining precision..."

Teacher Shi Lu and Teacher Xu Hua continued their discussion as they walked.

“The most obvious one is here!” Professor Xu Hua continued, pointing to the layout between the reactor compartment and the main engine compartment. “To ensure safety redundancy, we put the backup system for the main circulation pump here, which takes up a lot of space. In his sketch, this area is left empty, marked as ‘suitable for installing a more compact auxiliary power unit or expanding the living quarters’... Does this kid think we’re too conservative? Or is he implying that we can have more confidence in the natural circulation capability?”

"Why go through all this trouble? Why not just have a meeting and discuss it directly? Oh, right, could you just say he probably thinks we old fogies wouldn't accept this, or... he himself isn't entirely sure, and is just throwing out a suggestion?"

"Who would clearly label the density, parabola, and kinetic energy of a brick when throwing it? This is clearly a copy of the 'reference answer' solution steps just to make sure we can understand it!" Teacher Shi Lu gritted his teeth.

As they talked, the two walked to the open space outside the dormitory area.

Teacher Shi Lu stopped, glanced back at Jiangxia's quiet dormitory, and a complex understanding appeared in his eyes.

“I think I understand now,” he whispered to Xu Hua. “No wonder this kid was so obsessed with repairing ‘Early Tide,’ working himself to the bone. I’m afraid… he’s not just repairing submarines, he’s using ‘Early Tide’ as a ready-made, tangible reference point! He’s using our blueprints…”

Regardless of where he saw it from, he compared it to the real-life example of 'premature menstruation,' looking for differences and areas for improvement, and then incorporating his wildly imaginative yet seemingly well-founded ideas into it...

Finally, they produced this 'optimization suggestion' and threw it at us.

Teacher Shi Lu paused, his tone becoming serious: "However... Xu Hua, when you convene the core group for a meeting to discuss these diagrams later, I suggest... it's best not to mention this kid's name publicly."

"What?!" Teacher Xu Hua looked up abruptly, her eyes behind her glasses widening instantly, and a blush of anger quickly rose on her face.

"Well, Lu Da Nao! I was wondering why you're always clinging to people like a little kid, calling them 'godfather.' You've got a real emotional connection right here! What are you trying to do? Steal someone else's ideas and credit?"

I tell you!

impossible!

Absolutely impossible! "
