What does it mean to get a perfect score on the college entrance exam but then go missing?

Yu Qiang immediately took out his phone.

If we're talking about experts, then we'll have to consult the big names in academia.

It just so happens that Yu Qiang had some interaction with Northwestern Polytechnical University when he was handling a case before.

"I have Professor Yang's phone number from Northwestern Polytechnical University. Let me ask him."

Chen Xianghui: "Professor Yang? Which Professor Yang?"

"Professor Yang Hewei, from the School of Aeronautics and Astronautics at Northwestern Polytechnical University."

Chen Xianghui was somewhat skeptical: "Isn't he a chemistry major? How can he possibly do it?"

"You're kidding!"

Yu Qiang sneered.

"Yin is an academician of the Chinese Academy of Sciences, a leading figure at the university, and the most cultured person I know. If he can't figure it out, then there's only one possibility left."

Chen Xianghui: "What's possible?"

"These chemicals are not related to each other."

……

……

at the same time.

School of Aeronautics and Astronautics, Harbin Institute of Technology.

This place is practically like an assembly line.

The YJ3A's test flight was a resounding success, marking the Yunji project's complete transition from theory to mass production.

As the initiators of the project, the Aeronautical Institute and Xi'an Aircraft Industry Group bear the important responsibility of demonstration and planning.

In particular, those directly responsible, such as Gong Jianping and Yang Hewei.

They were all assigned three to four important titles and were responsible for the important mass production matters of the Yunji project.

"I'm truly impressed."

Gong Jianping couldn't help but grumble.

"The Commission for Science, Technology and Industry for National Defense is treating our Aeronautical Academy like a nuclear-powered ox or horse."

"We also have to do the certification for the materials industry chain."

"We both work on structural design."

Yang Hewei gave a helpless wry smile: "There's nothing we can do. The Yunji project originated from the institute. With great power comes great responsibility."

"That's true."

Both Gong Jianping and Yang Hewei experienced both pain and joy.

Being busy with something productive is always better than just busy doing nothing.

The higher-ups assigned these tasks to the School of Aeronautics and Astronautics because they valued the school's capabilities.

Since the final result of this project was achieved by Qin Ze and his team, it can be considered a project of the School of Aeronautics and Astronautics in any case.

So the School of Aeronautics and Astronautics benefited from Qin Ze's meteoric rise.

We're busy because the higher-ups believe the School of Aeronautics and Astronautics has made the greatest contribution and has the strongest capabilities.

Once this project is fully completed, the School of Aeronautics and Astronautics at Northwestern Polytechnical University will undoubtedly surpass other universities in terms of status.

"Hey, by the way, where's Qin Ze lately?"

Gong Jianping couldn't help but feel a pang of nostalgia when he thought of that confident young man.

"This project was originally his achievement."

"Now it's time for mass production and application; it's time to see results."

"In the end, he didn't show up, which benefited those of us who got something for nothing."

Yang Hewei shook his head helplessly: "I don't know either. I heard from the principal that Qin Ze doesn't seem to be involved in the mass production of Yunji."

Gong Jianping: "You think you can just abandon them after developing it?"

"Of course," Yang Hewei said matter-of-factly. "They handled the hardest part, and we can take care of the rest of the miscellaneous tasks."

The theoretical and research and development phases are the most difficult and demand the highest level of ability.

After the test flight, the work left behind is relatively simple.

It's simply a matter of mass-producing all the technologies and materials from the prototype.

In fact, Yang Hewei also agreed that Qin Ze should not participate in the subsequent mass production preparation work.

This way, we can use our best resources where they are most needed, allowing Qin Ze's abilities to be utilized to the fullest extent.

"I heard that Chen Ze is currently in Shangdu Town, leading a group of graduate students and special training students. I don't know what kind of project he's working on," Yang Hewei said.

"Oh? Really?" Gong Jianping was somewhat intrigued. "Then it must be a big project?"

Yang Hewei: "It doesn't seem like it. If it were a big project, professors like us would know about it and could go and help out..."

Before he could finish speaking...

suddenly!

Buzz-Buzz-Buzz-

Yang Hewei's cell phone vibrated in his pocket.

He subconsciously took out his phone, stared at the caller ID, and fell into deep thought.

"The police? What do the police want with me?"

Gong Jianping: "Huh?"

"Captain Yu from the criminal investigation team, I don't really have any interaction with him, we've just bumped into each other..."

He was hesitant.

Yang Hewei answered the phone, and Yu Qiang on the other end was very polite.

Hello, Professor Yang? I'm so sorry to bother you, is this a convenient time to talk?

Yang Hewei: "Captain Yu, you're too kind. What's the matter?"

I'd like to ask a question about an academic matter.

Yang Hewei: "Huh?"

"Here's the thing, we have a case that involves science, but as you know, we're all rather rough and lack the knowledge to figure it out, so we're asking you for help."

Yang Hewei quickly replied politely, "Captain Yu, you're too modest. Please ask me anything, and I'll do my best."

【Okay! Thank you in advance, Professor Yang!】

Here's the thing: I wanted to ask, if I bought polyethylene glycol, polyisocyanate, cellulose acetate butyrate, high-energy plasticizer, ammonium perchlorate, aluminum powder, 2-nitrodiphenylamine, triphenylbismuth (TPB), ferric oxide, chromium oxide, etc. online...

[By buying these raw materials, can you deduce what I intend to do with them?]

On the phone, Yu Qiang spoke as if reciting a menu.

Yang Hewei was stunned.

Gong Jianping, who was standing nearby, also sensed something was off and unconsciously leaned closer, saying, "Say it again."

Yang Hewei: "Captain Yu, could you please repeat that again?"

[Includes polyethylene glycol, polyisocyanates, cellulose acetate butyrate, high-energy plasticizers, ammonium perchlorate, aluminum powder, 2-nitrodiphenylamine, triphenylbismuth (TPB), ferric oxide, chromium oxide...]

"hiss!"

The two professors' CPUs immediately went red-hot.

It's normal that others don't recognize these compounds.

Because they are a relatively niche group, and there is no strong connection between them.

Even experts in chemistry might not be able to figure it out.

Unfortunately, they ran into Yang Hewei and Gong Jianping.

These two are absolute giants in the domestic aviation industry.

Gong Jianping blurted out, "NEPE?"

【What E?】

There was a two-second silence on the phone.

Yang Hewei then explained, "The composition looks like a formula for a solid fuel, which is generally used in strategic missiles or space shuttles."

【Huh? You mean—someone's manually crafting missiles?】

Yang Hewei also found it somewhat unbelievable.

That's how it appears on the surface.

"But the formula for NEPE, a solid fuel, is a state secret."

"And one thing I can reveal is that this is the latest technological approach, which the country has not yet fully mastered."

"So I think we can basically rule out the possibility that they are making NEPE."

Yang Hewei's argument is logical.

China Aerospace Science and Industry Corporation and Chongqing University of Technology have only just begun to explore this area, and even the formula is kept secret. It is even less likely that the private sector can crack it.

【But!】

Yu Qiang sounded like he hadn't said enough on the phone.

It couldn't have been a coincidence that he bought these things.

Yang Hewei lowered his voice, his expression grave: "So, there's another possibility..."
