Card maker? No, I'm a mechanic!

Soon, the sizzling, oily roasted meat was served.

It must be said that Li Kai has a good eye for choosing stores.

This restaurant's grilled meat is generously portioned and wildly seasoned, with every bite bursting with meaty flavor.

When paired with the owner's homemade chilled fruit wine, it becomes even more irresistible.

Su Man seemed to have gotten into the swing of things, and her movements became increasingly casual.

Occasionally, some sauce would get on the corner of her lips, which she would gently lick off with the tip of her pink tongue.

In this lively little shop, the initial awkwardness melts away in the subtle ambiguity.

"Phew...that feels good."

After putting down the empty skewer, Jiang Zhe finally let out a satisfied sigh.

Although the meat here can't compare to the meal at the Lin family's house, the owner's barbecue seasoning makes up for it perfectly.

Perhaps I should find an opportunity to learn from the boss?

Just as Jiang Zhe was pondering how to get information out of him, the SIM card in his pocket suddenly vibrated.

He took it out and saw that it was a text message from Lin Xiaoya.

"The items have arrived; they're at the side gate of the academy."

Upon receiving the message, Jiang Zhe picked up the deep-sea mithril that was placed aside, stood up, and glanced at the alluring scenery with some regret.

"Now that we've eaten and drunk our fill, it's time to get down to business."

"But... where's the side door? I thought she'd escort me to the main gate."

"I'll lead the way."

Su Man gracefully picked up a tissue to wipe her mouth, then put her uniform jacket back on, partially concealing the startling sight.

"The side gate is located at the junction of the weapon-refining department and the logistics department, mainly to facilitate their transportation of materials."

She stood up, her high heels making a crisp sound on the ground.

"I'm getting more and more excited to see what your finished product will look like."

After paying the bill and leaving the barbecue restaurant, the two walked along a tree-lined path towards the depths of the college.

The sun was shining brightly, and most of the students who had finished lunch had already returned to their dormitories.

"Zzz... Zzz..."

But just as the two turned a street corner, a piercing metallic scraping sound came from ahead.

The sound was like rubbing your fingernail on a blackboard, making your teeth ache.

Jiang Zhe looked in the direction of the sound and saw a boy in gray overalls struggling to drag a large object along the road.

It appeared to be an arm about half the height of a person, with a simple and rugged design.

However, the surface of the arm was completely dull at this moment, not only emitting black smoke but also occasionally sparking at the joints, clearly in a state of semi-scrap.

"That's Zhang Yuan from the weapon-refining department, and also Professor Wang's student next door."

Su Man first explained to Jiang Zhe in a low voice, then raised her voice and shouted at the boy:

"What are you doing? Going to Taobao again?"

"Senior Su?"

Upon hearing this, the boy named Zhang Yuan stopped in his tracks, a look of helplessness on his face.

"Don't even mention it. I spent a fortune to acquire this puppet arm, and it broke as soon as I activated it."

He sighed and patted the smoking arm with a hint of heartache.

"I consulted several teachers, and they all said that the core component was broken and difficult to fix. Even the professor said it could be repaired, but the cost would be too high."

"The only option is to try and find a fool on the black market to sell it to."

"Sigh... I saved up this money by scavenging for junk for months."

As he spoke, he dragged the arm and walked toward the side door.

Jiang Zhe's gaze involuntarily swept over that arm.

In his field of vision, those complex runes and loops were instantly dismantled.

You can clearly see where there are blockages and short circuits.

"Wait a moment."

Jiang Zhe suddenly called out to him.

"Hmm? You want to buy it?" Zhang Yuan stopped and looked at the stranger following Su Man with some doubt.

"I'm not an idiot, but what I want to say is that your core isn't broken."

Jiang Zhe stepped forward and pointed to an inconspicuous rune on the inside of his elbow.

"The problem lies here."

"The circuit here has become inefficient and rusted, but the power supply line still prioritizes that area, so that place definitely can't withstand the smoke."

"Fortunately, there is a backup route nearby, so you can completely cut off the rusty part and let the energy get smarter and give up on taking this route."

"Huh? What is that?"

Zhang Yuan was stunned, looking at Jiang Zhe in disbelief.

"Really? How did you figure that out?"

Believe it or not.

Jiang Zhe pursed his lips, too lazy to explain, "Trying it doesn't cost anything."

After saying that, he didn't linger and followed Su Man towards the side door.

Zhang Yuan stood there, watching Jiang Zhe's departing figure, and then glanced at the pile of completely inexplicable runes.

After a while, he gritted his teeth, took out a screwdriver from his work clothes, and stabbed it into the hole.

"Sizzle..."

As the sound came, the energy that was originally crammed into the rusty circuit quickly changed direction.

"Buzz..."

"Holy crap, it really works!?"

Zhang Yuan's eyes widened, and a look of wild joy appeared on his face.

"Wow, that's awesome! This guy is definitely a pro!"

……

the other side.

"What else can you fix?"

Su Man turned her head to look at Jiang Zhe, her curiosity growing even stronger.

She knew how arrogant the teacher who taught weapon crafting was, someone who could make even them feel troubled, yet this guy saw through the problem at a glance?

"I know a little, I know a little."

Jiang Zhe smiled and the corners of his mouth turned up.

"Once you understand the principles, fixing things is as simple as eating and drinking."

He stroked his chin, but was thinking about something else.

If card-making shops don't do well in the future, opening a Jiang's Repair Shop seems like a good option.

Or they can make a name for themselves by sitting at the entrance of a historical site and fixing whatever is broken.

If you come across something good, just say you can't fix it, and maybe the person will sell it to you at a discount.

While they were thinking, the two had already arrived at the side door.

The delivery truck arranged by the Lin family had been waiting for a long time.

Upon seeing them, the driver immediately jumped out of the car, opened the trunk, and revealed two suitcases that were packed full.

"The portion is really generous, as expected of the Lin family," Jiang Zhe remarked.

With the driver's help, the two of them worked together to unload the two heavy boxes from the car and carried them all the way to the laboratory entrance.

……

"Click".

As the heavy doors closed, the noise from the outside world was shut out of the laboratory.

Jiang Zhe slammed the two large boxes of materials onto the ground with a thud and let out a long sigh.

"Phew... I'm already starting to miss Li Kai."

He flexed his wrists, then placed the fist-sized piece of deep-sea mithril on the table, his gaze becoming focused.

"Suman, could you turn down the temperature of that array for me? It's getting a bit hot."

"OK."

Su Man did as she was told, and then leaned closer to observe Jiang Zhe's every move.

Although she was reluctant to admit it, she gradually realized it.

That means everything she had learned was insignificant compared to this man.

What he demonstrated was even advanced technology that she couldn't understand at all.

"First of all, this is it."

Jiang Zhe closed his eyes, and his mental energy quickly surged out to envelop the hard metal.

"Buzz..."

Under the influence of spiritual energy, it shone almost instantly.

It then melted into a black, liquid mass of light, like a candle.

This basic process was already second nature to Jiang Zhe, whose mental strength was becoming increasingly refined.

With a slight movement of his fingers, a piece of the ball of light was separated and stretched and rotated in the air.

In just a few breaths, the delicate circuit was formed and landed steadily on the worktable.

"Now comes the main event."

Having figured out the nozzle's circuitry, Jiang Zhe turned his attention to the cards.

"Water jets serve as a carrier, earthen walls extract microparticles, and wind blades can simultaneously perform multi-stage pressurization while cutting..."

He quickly constructed a model in his mind, and the carving knife in his hand moved accordingly.

Unlike his previous casual handling of materials, he now resembled a neurosurgeon performing a delicate operation.

"Sizzle."

With a few slashes, the wind blade card's loop was severed.

He forcibly twisted the loop into a spiral structure.

Then, the energy is split into three streams using energy-conducting wires, which are then connected to the different pressure chambers representing the modified pump body.

"The loop performance after this modification may be even better than before."

A hint of satisfaction flashed through Jiang Zhe's mind.

Next came the earthen wall.

Instead of drastically altering the earthen wall, he precisely extracted several energy nodes responsible for its embodiment.

The carving knife flew, and the wires were connected.

Under Su Man's increasingly shocked gaze, the core circuits of the three cards, which should have been unrelated, were revealed.

Jiang Zhe forcibly pieced them together in an extremely bizarre yet logically beautiful way!
