Card maker? No, I'm a mechanic!

It was a rather imposing-looking building, but the main gate had long since disappeared.

Jiang Zhe crept closer and observed the doorway for a while, confirming that there were no obvious dangers or traps.

He then cautiously walked in.

The building has a large interior space, and there are some metal fragments of unknown purpose scattered on the ground.

On the inside of the wall, some structures resembling shelves can still be vaguely discerned.

However, the top was completely empty, not even a single screw remained.

"It's cleaner than if a dog had licked it."

Jiang Zhe shook his head with some regret.

"But that's normal, considering this is considered an outer area."

"Even if there were any good things, they would have been looted by the previous explorers long ago."

Despite this, he did not give up hope.

Instead, they used the eyepiece to search through those inconspicuous nooks and crannies.

"Click".

As a metal plate was pried open, a small, palm-sized silver box was revealed.

Upon seeing this, Jiang Zhe's eyes lit up, and he quickly picked it up and examined it closely.

"This seems to be... some kind of energy storage unit, or perhaps a battery?"

The box had some simple patterns engraved on its surface. Although it was quite worn, one could still feel faint energy fluctuations emanating from within.

"Looks like there's not much power left, but I'll keep it anyway, it won't take up any space."

After putting the box away, Jiang Zhe felt a little better.

Even a mosquito's leg is still meat; as long as you have the skills, you can turn waste into treasure.

However, just as he was about to continue exploring further...

A low, humming sound faintly came from deep within the building.

"Buzz...buzz..."

The sound was soft yet carried a certain rhythm, like some kind of machine in operation.

Upon seeing this, Jiang Zhe's heart skipped a beat. He turned around and quickly shrank into a shadowy spot, slowing his breathing.

"What's that noise? Is it the guards?"

He pulled out a floating cannon card with his backhand and activated it by injecting his mental energy.

"It's alright, luckily I have a third eye."

The next moment, the metal ball floated up silently, skimming along the ceiling and gliding in the direction from which the sound came.

Through the mental connection, Jiang Zhe's vision also expands.

On a long corridor deep inside the building, several strange figures were moving slowly in a group.

Those looked like several... puppets, about half a person's height?

They are made entirely of some grayish-white material, and their surfaces are inlaid with metal plates of varying sizes, giving them a very rounded appearance.

On their torsos, several green runes flickered and glowed with their movements.

"Is this the recorded guardian of the ruins?"

Jiang Zhe frowned, but quickly realized something was amiss.

Because these puppets had no weapons or offensive equipment in their hands or on their bodies.

Instead, there are several suction cup-like devices on the underside of their bodies.

As they moved forward, even the finest dust, debris, and rust on the ground were continuously sucked into the suction cups.

And the places they passed through quickly became spotless, just as they appeared from the outside.

"This is... a fully automatic intelligent robotic vacuum cleaner?"

Jiang Zhe was both amused and exasperated.

"So the outside is so clean because these guys work so hard."

These appear to be merely auxiliary puppets responsible for cleaning, and should pose little danger.

"However... since it's a puppet, it should have some good stuff on it."

Jiang Zhe stroked his chin, a glint of shrewdness flashing in his eyes.

The still-functioning puppets found in these ruins are excellent research materials for him.

As he was pondering this, he suddenly noticed that one of the puppets at the end of the line had stopped for some unknown reason.

Its body trembled slightly, as if the suction cup at its bottom was stuck by some metal fragment.

This caused it to gradually fall behind and drift away from the group of workers ahead of it.

"What you wish for comes true; now there's someone all alone."

Seeing this, Jiang Zhe couldn't help but smile. "Then don't blame me for being impolite."

Immediately afterwards, he silently maneuvered the floating cannon to hover above the head of the unfortunate lone creature.

"Perfect timing to test the new feature on you: electronic interference, activate!"

"Sizzle..."

The next moment, an invisible wave emanated from the core of the floating cannon, precisely enveloping the puppet.

The puppet, which was trembling and working, was affected and froze in place as if its Bluetooth connection had been disconnected.

The green runes on the surface of the torso began to flicker violently, like a computer infected with a virus, before going out completely after a few seconds.

Electronic warfare, a resounding success!

"Is that all? It seems easier than I thought."

Without hesitation, Jiang Zhe dashed forward.

In an instant, he strode forward and grabbed the puppet's shoulder.

He quickly dragged it into an empty room next door with force.

"These guys are really inflexible."

After finishing all this, Jiang Zhe couldn't help but look back at the cleaning team that was still moving forward and couldn't help but complain.

"Nobody even bothers to look back after losing teammates. What a cold and indifferent workplace relationship."

With a casual pull aside the obstruction, Jiang Zhe began to examine this unexpected discovery.

The puppet was exquisitely constructed, with all its joints fitting together perfectly.

Even after working for countless years, it still functions perfectly.

"It's okay, they don't care about you, so I'll do it. And while I'm at it... let me see where your heart is."

Jiang Zhe's carving knife flew through the air as he skillfully pried open a large plate of armor on the puppet's chest.

The next moment, a complex array of runes came into view, which was clearly the core part controlling this body.

"Let me see, if we just cut off this part and then bypass this alarm loop..."

He carefully severed several of the main rune paths.

As the last glimmer of light faded, the puppet went into shutdown mode.

"Alright, now it's time for the dissection."

Jiang Zhe rubbed his hands together, just about to delve deeper into the research.

But just as his gaze inadvertently swept over the puppet's arm, he suddenly sensed something unusual.

"Wait a minute, something seems off about this rune."

On the inside of the puppet's wrist, there was an inconspicuous red rune.

The key is the style of this rune, which is completely different from the overall rounded style of the puppet.

It appears sharper, and also seems to have a hint of... a modified, rougher look?

"This doesn't look like the original."

Jiang Zhe frowned and tentatively channeled a wisp of mental energy into the rune in an attempt to activate it.

"Snap!"

But the moment the runes lit up, something unexpected happened.

The puppet's originally round fist suddenly broke off in the middle without warning and slid to both sides.

At the severed point, a gleaming blade suddenly sprang out!

The blade was not formed from a single piece, but rather forcibly pieced together from some unknown metal fragments.

Although it is sharp, the splicing marks are clearly visible, and the joints are even a bit stiff.

"Oh, this..."
