Card maker? No, I'm a mechanic!

"..."

Su Man's smile froze on the spot.

"puff……"

She blinked, and it took her a while to recover before she sat back down in her chair with a sigh.

Su Man straightened her slightly disheveled collar and then re-tied up the parts that were sore from being squeezed.

She then rolled her eyes at Jiang Zhe, her eyes full of resentment.

"Jiang Zhe...you really have no sense of romance. Don't you think it's a killjoy?"

Su Man muttered something, her tone somewhat complicated.

"What? Do you think it's not enough?" Jiang Zhe pretended not to understand, raised an eyebrow, and added.

"How about adding another hundred?"

"No! Three hundred it is, I'm really scared of you."

Su Man quickly waved her hands and begged for mercy, afraid that the amount would really be increased.

"Alright, now that we've eaten and drunk our fill, it's time to get back to work."

After stuffing the last piece of pork belly into his mouth, Jiang Zhe stood up and went straight to the counter to pay the bill.

As the two walked out of the barbecue restaurant side by side, they immediately attracted many curious glances.

"Isn't that Senior Su Man...?"

"Who's that next to her? She looks unfamiliar, is she new?"

"I don't know, but to be able to have dinner with someone of Su Man's caliber, he must be some young master from a wealthy family."

Jiang Zhe ignored the whispers, and Su Man was already used to being watched.

"That's the one in front."

After bypassing the crowd, Jiang Zhe pointed to a shop not far away.

It used to be a closed-down grocery store, but now it's completely surrounded by blue construction barriers.

There wasn't even a signboard; it looked quite mysterious.

"We've had this shop for almost two weeks now, why is there still no sign of anything happening?"

A couple passing by were pointing at the shop and whispering to each other.

"My second uncle's sister's brother-in-law works there. I heard it's quite mysterious, like some kind of car modification shop?"

"What? Wait a minute... isn't that your dad?"

"You guessed it..."

Upon hearing this, Jiang Zhe couldn't help but smile. Mystery is the best marketing.

He opened the small door in the partition, stepped aside to let Su Man go in first, then crawled in himself and locked it with a click.

This scene immediately became a topic of gossip among passersby.

"Holy crap, they went in? A man and a woman alone together..."

"Is this shop just a front?"

……

In the store.

Although it is not completely finished yet, the basic work has been done.

The white walls and minimalist metal display cabinets exude a professional atmosphere.

"The environment is nice."

Su Man looked around, a hint of surprise flashing in her eyes.

She had initially thought that Jiang Zhe's straight-male aesthetic would make the shop look like a shady roadside workshop, but she was surprised to find that it was quite stylish.

"That's natural."

Jiang Zhe walked to the wall on the left and gestured.

"This is the counter I plan to use to display the blindness cards, focusing on high volume sales."

However, he then pointed to the counter directly opposite him, a shrewd businessman's smile on his face.

"And here, I'll put my anti-flash card."

"Let customers buy the spear, and then they can immediately see the shield."

"They definitely can't resist the sense of security that comes with buying it and being able to throw flashbangs at will."

Su Man pondered the scene for a moment, then, as if suddenly remembering something, couldn't help but ask.

"Could you teach me how to use this anti-flash card?"

"No rush, I will definitely teach you, but I'm not selling it now."

Jiang Zhe waved his hand, a mischievous smile playing on his lips.

Good things have to be revealed little by little.

"If we release it now, the deterrent effect of the blinding card won't be established yet, and people will just buy it out of curiosity."

"They need to suffer the consequences of the blinding card in various places, until they are blind, frustrated, and in unbearable pain..."

"Then I'll take out the antidote."

Jiang Zhe snapped his fingers. "Isn't that just bailing out people in distress, only to have it sold out instantly?"

Su Man was taken aback by what she heard, then covered her mouth and chuckled softly, her eyes sparkling.

"Teacher Jiang is absolutely wicked..."

"Thank you for the compliment," Jiang Zhe said, looking pleased.

"Alright, now that I've shown you the workplace, let's get back to work."

"Since it's going to be mass-produced, we definitely can't skimp on raw materials."

As he spoke, he raised an eyebrow and looked at Su Man.

"Employee Su, now it's your turn to shine."

"Use my position as a teaching assistant to apply for a batch of flash cards from the logistics department."

"The reason... is that Professor Lin's laboratory needs to conduct relevant research and requires a lot of consumables."

"This... is this considered taking advantage of the academy and professors?" Su Man's eyes widened.

"How can you call it 'taking advantage' when it comes to academic pursuits?" Jiang Zhe said righteously.

"This is all for academic advancement! Just think, how much combat power would be boosted if this were widely adopted?"

……

Half an hour later, inside the laboratory.

Su Man walked in carrying a large box of flash cards, panting heavily, with a fine layer of sweat on her forehead.

Here, the supplies you requested.

"Well done!"

Jiang Zhe picked up a card and examined it. These were all standard-issue cards, of stable quality, perfect for modification.

These are the perks you should enjoy as a teaching assistant.

"Come on, sit down. Now we're getting ready for class."

Jiang Zhe pulled over a chair and gestured for Su Man to sit at the worktable.

He stood behind her, his hands supporting him on the edge of the table, forming a semi-encircling posture.

"Last time I just had you do the work, but this time it's different."

"The drawing you did at the dinner table was too hasty; it's normal that you can't understand it given your current skill level."

After saying that, he took the flash card and pointed to a loop on it.

"Look here, it's actually the main energy output channel of the flash card."

"Under normal circumstances, it's just an ordinary faucet; the water flow is steady and won't hurt anyone."

Su Man nodded; she understood this basic principle.

"What we need to do is to block the faucet and then add a 'reservoir' to it."

Jiang Zhe traced the name on the card with his finger.

"Block the energy that should have been released, and let it accumulate and compress in the reservoir."

"And when you reach the pressure threshold, that is, the moment you activate the card."

"With a bang, the blockage was blasted open, allowing all the energy to be released instantly under pressure."

"At that point, it wouldn't be a light bulb, but a flashbang."

Hearing such a simple analogy, Su Man suddenly understood.

"I see," a hint of understanding flashed in her eyes, "So you wanted to cut off the loop here to create a blockage?"

"clever."

Jiang Zhe nodded approvingly.

"But..." Su Man frowned again, looking at Jiang Zhe's completely illogical gestures.

"Is this kind of loop really okay? The book says you have to go with the current."

"Your books are for idiots."

Jiang Zhe interrupted her directly, a confident smile playing on his lips.

"By making such a modification here... its reverse flow will become a backflow boost."

"This is my unique technique."

Su Man watched as Jiang Zhe's circuit became increasingly complex, though she already had a general understanding of the concept.

However, the underlying logic remains only partially understood.

It's like knowing how to use a computer and fix it, but not knowing how to make a computer.

Su Man took a deep breath, her eyes sparkling with excitement.

This unconventional unknown is more fascinating than any knowledge one has acquired.

"This is what I wanted..."
