Card maker? No, I'm a mechanic!

Chapter 138 Restrictions on Minors

"Tomorrow at noon! Don't forget!"

"This time, however—"

"Okay, okay, I won't forget," Jiang Zhe interrupted her abruptly, his ears hurting from her loud voice.

"Just tell me where to play, didn't you want to decide on a location?"

"Medicine—no, that's not right."

Leia was delighted upon hearing this, but she suddenly stopped mid-sentence.

She originally meant to say it was the small garden downstairs from the hospital, since it was impossible to go to the wrong place, and she didn't know the area.

But when she thought of Li Mo, who had been bothering her all along, and the teacher who would definitely be in a bad mood after the meeting, she immediately chickened out.

"Uh... well... never mind..."

Leia shook her head and remained silent for a moment before finally giving her answer.

"You decide. Just make it easy to recognize, nothing too complicated."

"Let's go to the abandoned training ground behind Tianlan Academy. There's only one straight road there, so it'll be easy to find."

Jiang Zhe casually mentioned a place.

"Okay! It's a deal then!"

"Snapped!"

However, just as Leia finished speaking, a sudden burst of noise came from the other end of the communication.

Immediately afterwards, a deep male voice, tinged with anger, rang out.

"What makes you say it's a promise? I just finished a full day of meetings, and Li Mo is already telling me you've been secretly contacting outsiders and running around?"

"Ah? That traitor Li Mo! He actually betrayed us?" Lei Ya's scream rang out.

"Lie back down, your communications are confiscated!"

"Huh? Teacher? I was wrong, please give it back to me!"

"Buzz—Buzz—"

Amidst a cacophony of pleas for mercy and sounds of looting, the communication abruptly ended.

Looking at the dimmed card in his hand, Jiang Zhe's lips twitched involuntarily.

What is this?

Is communication restricted for minors?

"Pfft—"

Su Man, who was playing on the same plate, had obviously heard the commotion and couldn't help but cover her mouth and chuckle.

"Things don't look good."

"Hard to say."

Jiang Zhe put away the SIM card and shook his head.

"Given her personality, she'd probably crawl over here even if she had to."

"but----"

As he spoke, he narrowed his eyes, seemingly lost in thought.

"Is that Raymond, judging from the noise?"

"Why is this old man suddenly thinking of arresting students instead of sleeping at night?"

Without further ado, the vehicle stopped at the entrance of the college.

The two returned to the laboratory, and as the door clicked shut, the world returned to silence.

"Alright, that's the end of my vacation for today."

Jiang Zhe clapped his hands, his expression turning serious.

"Now is the time to keep our promise."

"real?"

Upon hearing this, Su Man's eyes lit up, and she immediately abandoned her gossipy thoughts.

She walked quickly to the worktable, even straightening her clothes to look like a model student.

"Teacher Jiang, what are you going to teach me this time?"

"this."

Jiang Zhe pulled over a sheet of white paper, then picked up a pen and started sketching quickly on it while talking.

"The blinding card has been out for a while now, and those who managed to snag it on the first release have probably already used it to annoy quite a few people."

"Therefore, it's time to launch the antidote and close the business loop."

"And what I'm going to teach you now is the core filter circuit of the anti-blindness lens."

Su Man leaned closer to take a look and saw that what Jiang Zhe had drawn was not a rune array, but some strange patterns that she had never seen before.

"What is this?" she asked, pointing to a wavy line, her face full of confusion.

"This is a light wave."

Jiang Zhe didn't even raise his head, just flipped his wrist.

"Simply blocking the light isn't that effective, and the blinding card also has strong penetrating power."

"Therefore, we need to create a special refractive layer at this point."

He pointed to a polygonal structure on the paper.

"See this? This is called a polarization filter matrix."

"Utilizing light of different wavelengths in a specific medium —"

"Polarization — filter matrix?"

Suman murmured softly, even though these words and the structure on the paper seemed to have no connection whatsoever.

But as she listened to Jiang Zhe's gradual explanation, she vaguely sensed that it contained a kind of extremely rigorous logic.

"Moreover, this time it's not just about drawing a picture."

Jiang Zhe put down his pen, but his gaze suddenly fell on Su Man's face.

"May I borrow your glasses?"

"?"

Before Su Man could react, Jiang Zhe leaned over.

He reached out and gently removed the gold-rimmed glasses from her nose.

"you----"

Su Man felt a blur before her eyes, her vision became blurred, and her gaze instantly turned strange.

Is this guy genuinely unaware or just pretending?

"What we're going to do this time isn't to modify the cards, but to transplant the loop onto objects."

Jiang Zhe, however, didn't pay attention to Su Man's thoughts. Instead, he simply held up the glasses to the light and showed them to himself.

"What? On an object?" Su Man was startled by the words, and her attention was instantly drawn back.

"That's right."

Jiang Zhe nodded, his expression becoming more serious.

"Modifying cards is the simplest thing, because cards were originally designed to hold loops."

"But ordinary objects are different; different materials naturally have different capacities for carrying energy circuits."

As he spoke, he took a small piece of metal and melted it with his spiritual power.

"Therefore, we need to use our mental energy to shape it into an extremely fine circuit structure."

"Then, like a brand, it is instantly embedded into the surface of the object, allowing it to resonate with the material and form a stable energy field —"

Picking up the carving knife, Jiang Zhe gently touched the edge of Su Man's glasses lens.

"This is like performing micro-sculpting on a strand of hair; it's probably several times more complex than card modification."

"However, this is also the first step toward higher-level technology, namely the replication of heritage artifacts."

Upon hearing this, Su Man's eyes instantly turned fervent.

That's right, she worked herself to the bone for so long, all for Jiang Zhe's big prize, didn't she?

"I want to learn!"

She took a deep breath, then snatched the glasses back from Jiang Zhe and put them back on, her eyes resolute.

However, reality was far crueler than her ideals.

For the next few hours, the laboratory was filled with Suman's frustrated sighs.

"No, the force was too great, the lens cracked."

"It's broken here, the loop can't be reconnected."

"They overlapped————"

The discarded lenses began to pile up into a small mountain on the table.

Su Man rubbed her sore wrists, her forehead covered in sweat.

This technology is much more difficult than she imagined!

Not only must one control the output of mental energy, but one must also pay close attention to changes in the materials at all times; the slightest carelessness could lead to the loss of all previous efforts.

"Don't rush."

Jiang Zhe, who was watching from the side, was not surprised at all.

They even stretched leisurely.

"This kind of micro-management technique requires a lot of practice and patience."

"Even with my guidance, it's not that simple for you to understand it."

"Alright, that's enough for today."

Seeing that Su Man looked completely drained, Jiang Zhe called for a stop.

"These things can't be rushed. Write down the principles first, and then review them slowly when you get back."

"Um----

Su Man nodded, though she was still somewhat unwilling, she understood the reasoning behind it.

She reached up and rubbed her temples, forcing herself to suppress her frustration.

"But even if you master the technique, the output won't be that high."
