Card maker? No, I'm a mechanic!

"Don't worry, Mr. Lin, this time it's different."

"That's good. You can handle it yourself. I still have to deal with those idiots."

After saying that, Professor Lin hung up the call.

"Buzz..."

As the light on the card faded, the ward returned to silence.

After putting away the SIM card, Jiang Zhe leaned back and sank lazily into the soft chair back.

It was already evening.

The sky outside the window gradually darkened, and the afterglow of the setting sun shone through the glass onto the ground.

"The path behind this has been cleared."

Looking out the window, Jiang Zhe's brain started working at lightning speed again.

"Then all that's missing is a bomb that's conspicuous enough."

Creating an explosion isn't difficult; the challenge lies in making the commotion more noticeable.

"Anyway, the doctor said it's nothing serious, so we might as well just run away."

With this thought in mind, Jiang Zhe no longer hesitated.

He quickly packed a few things and then took advantage of the nurses' shift change.

He swaggered out of the hospital as if nothing had happened.

……

More than an hour later, at the Tianlan College Experimental Building.

"Click".

With a soft click, the heavy metal door was pushed open.

Su Man, who was taking a nap on the table, was also awakened by the noise.

She rubbed her slightly sore neck and subconsciously assumed that it was that annoying young lady again.

"Oh, the second-in-command has been dismissed?"

She didn't even look up, her tone carrying a hint of casual teasing.

"Is today's theory class over?"

"It's hard to say, it doesn't seem to have started yet."

However, the voice that responded to her was a somewhat familiar male voice.

Although it sounded a bit tiring, it was mostly filled with a kind of excitement to cause trouble.

"Kang Chul?"

Su Man was stunned. She looked up at the approaching figure, her eyes widening instantly.

"Why are you back?"

She glanced at the clock on the wall, then at Jiang Zhe, her face filled with disbelief.

"Weren't they saying the core area would take five days? We're only halfway through!"

"and……"

Su Man looked Jiang Zhe up and down. Although he was travel-worn, she couldn't see a single wound on him.

"Did you skip class?"

"What do you mean skipping class? That's graduating early."

Jiang Zhe shrugged and was about to pull up a chair to sit down when his gaze suddenly stopped.

"Hey? Where's my old table?"

He touched the brand-new, gleaming metal workbench in front of him and raised an eyebrow in surprise.

"Traded in your old car for a new one?"

"Of course we changed it."

Upon hearing this, Su Man rolled her eyes in annoyance and casually gathered up the cards scattered on the table.

"You dare mention that table? When the repairman came over today, he stared at it for quite a while."

He thought I was some kind of troublemaker who would add to his workload.

She pushed up her glasses, her tone carrying a hint of resentment.

"Look, this is an alloy platform specially prepared for saboteurs like you."

"It's cheap and sturdy."

"Tsk tsk, it feels like my hometown."

Jiang Zhe patted the cold tabletop with satisfaction, producing a series of dull echoes.

He then sat down and threw his backpack on the table.

"Something went wrong, the site was in an uproar, so we were all forcibly deported."

"Did it explode?"

Su Man was taken aback, clearly unaware of what was happening outside.

After all, in order to catch up on the progress these past few days, I wanted to finish before Jiang Zhe came back so I could learn new things.

She practically lived in the laboratory, completely in a primitive state.

"No wonder..."

As if remembering something, she pointed to a large box piled up in the corner.

"This afternoon, the old man sent someone over with a bunch of things, but left without saying anything."

"I was wondering where all this junk came from."

"So it was you who brought it here."

At this point, Su Man couldn't help but breathe a sigh of relief, and then her gaze toward Jiang Zhe became resentful.

"It's good that you're back."

Her tone suddenly turned sour.

"So that Lin Xiaoyou won't keep asking all sorts of questions."

"I don't think her mind is on making the cards at all; she's been drinking tea and taking breaks all the time..."

Su Man pursed her lips, clearly feeling threatened by this young lady who might endanger her status.

"You must remember who lives the best life."

"Don't worry, don't worry, this one still has to be yours."

Jiang Zhe offered a somewhat amused reassurance, then his expression turned serious as he cut straight to the point.

"Let's not catch up now, I have urgent business to attend to."

He stood up and quickly scanned the laboratory.

"I want to make something."

"What?" Seeing his serious expression, Su Man immediately stopped joking.

"A bomb."

Upon hearing this, Jiang Zhe grinned, revealing a set of white teeth.

"Yes, I need a firecracker big enough that the city garrison will have to deploy it."

"Bomb...?"

Su Man was startled and instinctively took a half step back.

"Are you crazy? This is an academy! Who are you trying to blow up?"

"Don't worry, it's just to make a sound for outsiders."

Jiang Zhe waved his hand and then began searching for usable materials.

"But I'm still missing something crucial."

"I need an unstable core, preferably one that ignites at the slightest touch."

"Unstable...core?"

Su Man frowned and pondered for a moment, then her eyes lit up as if she had thought of something.

Then, she quickly walked to another corner of the laboratory and dragged out a dusty metal box.

"If you're talking about that, then yes, there is."

"What is this?" Jiang Zhe asked curiously as he leaned closer.

"Professor Lin's masterpiece from a couple of days ago."

Su Man opened the box, revealing more than a dozen cards inside that glowed with an eerie red light.

"Didn't he spend a lot of time tinkering with replicating your displacement card?"

"And these are the failed products he accumulated."

She pointed to the cards, her tone tinged with helplessness.

"It wouldn't have been a big deal at first, but a couple of days ago he said he had some new ideas, and he started messing around with this pile of useless cards."

"As a result, the energy circuit is completely messed up, and now it's as active as a powder keg."

"The professor originally asked me to destroy them, but I've been busy with work these past two days and haven't had time to do so yet."

"Look at this... do you want it?"

"Be careful if you use it. If this thing blows up, the lab will be gone."

Jiang Zhe picked up a discarded card and sensed its violent energy; a glint of light flashed in his eyes.

"Don't worry, until I set the fuse, they're just explosive charges."

"The old man has done a great job this time."

He chuckled and then moved the entire box of discarded cards onto the worktable.

Immediately afterwards, he took out the amplification fragment that he had previously removed from the stone tablet.

"almost."

Jiang Zhe took a deep breath, and the idea in his mind quickly took shape.

Then, he pulled a bunch of purification cards out of his pocket.

"Next comes assembly."

"Is this the kind of barrier card you modified before?" Su Man raised an eyebrow.

"That's right."

Jiang Zhe continued working with his hands, offering a casual explanation.

"The modified purification card releases a stable, high-intensity small field to isolate the aura."

"What I need to do now is to compress this position again, and turn it into a pressure cooker."

"Then these unstable, discarded cards are packaged and stuffed inside as explosives."

"at last……"

He picked up the amplification fragment and gently rubbed it with his fingertips.

"Use this as an initiator."

"Once activated, the amplification fragments will amplify the explosive energy of the useless card several times over!"

"And this terrifying energy, unable to escape from the pressure cooker, will eventually burst the force field barrier in an instant!"

As he spoke, he spread his arms and made an explosion gesture.

"And at that moment, the purifying force field, compressed to its limit, will burst open like a balloon being blown up."

"It formed a gigantic energy ripple, several kilometers in diameter, visible to the naked eye!"
