Chapter 196 Who Isn't a Calabash Brother?

"No way, how is there an invisible one here?" Liu Jianguo exclaimed.

This exclamation was like pouring a ladle of cold water into a calm pot of oil, instantly causing the entire restroom, and even the corridor outside, to erupt into chaos.

Everyone's gaze locked firmly onto that corner.

The Experts who were originally outside directing the loading, upon hearing the commotion, rushed into the narrow men's restroom like cats smelling fish, disregarding all decorum.

In an instant, this tiny space of a few square meters gathered the sharpest minds of the Eastern Country Weaponry Industry Group.

At the focus of their gazes, the robot dog that had just materialized was tilting its head, holding the roll of white toilet paper in its mouth, looking both innocent and adorable.

Its body appeared in a semi-transparent state, like a ghost in a sci-fi movie, or an artwork carved from the purest crystal.

If you didn't look closely, you might even think there was only air there.

"This... how was this done?"

An old Expert specializing in optical camouflage, not caring about the dirty floor, lay directly on the ground and leaned in front of the robot dog, eyes wide as copper bells, staring fixedly at the mechanical legs that shimmered with a faint light.

He stretched out a trembling hand, wanting to touch it, but afraid of damaging this precious treasure, his hand hovered in mid-air, shivering.

"Incredible... simply incredible..."

The old Expert muttered to himself, as if possessed, "It's not just static camouflage. Look at its edges, the light is flowing! This is real-time! This is dynamic!"

Li Jiajun looked at this group of flustered Experts, speechless.

'Is it really that big of a deal?'

'It's just an invisibility function, right? Didn't that dragon rider toy car have it too? It's not like you haven't seen it before.'

This thought surfaced in his mind.

He turned around, patted the head of the transparent dog, and introduced it to Liu Jianguo and the crowd of onlookers:

"As you can all see, this is our factory's new product—Wangcai Sixth Child Model."

"Sixth Child?"

Liu Jianguo was stunned and subconsciously asked, "Why is it called Sixth Child?"

Li Jiajun answered matter-of-factly:

"Uncle Liu, haven't you watched 'Calabash Brothers'? The Sixth Child in Calabash Brothers has the ability to turn invisible, right?"

"This dog can turn invisible, so calling it the Sixth Child Model is so fitting, so culturally profound!"

Liu Jianguo's mouth twitched violently.

Damn that cultural profoundness.

"You named a military... er, civilian robot that possesses the world's top invisibility technology after a Calabash Brother?"

"If this gets out, how will those foreign Experts who are still losing their hair over invisibility coatings feel?"

However, now was clearly not the time to dwell on the name.

The optical Expert who was lying on the ground jumped up, grabbed Li Jiajun's arm, and stammered excitedly:

"Little Factory Director Li! This isn't just a matter of invisibility coating!"

"The previous 'dragon rider' car had a rigid body that didn't deform! So the coating only needed to handle light refraction on static curved surfaces!"

"But this... this is a dog! It has joints! It's moving!"

The old Expert pointed at the wagging robot dog, his voice shrill and cracking:

"Once the joints move, the angle of the surface coating changes drastically, and the light refraction path gets disrupted! Logically, as soon as it moves, the invisibility effect should immediately fail, turning it into a blurry patch of light and shadow!"

"But just before it materialized, it clearly performed the action of handing over paper, yet none of us saw it!"

"What does this mean? It means it has solved the problem of real-time light compensation during dynamic deformation!"

"This is dynamic optical invisibility!!"

The more the old Expert spoke, the more excited he became, with spit spraying onto Li Jiajun's face.

The surrounding Experts gasped after hearing this, and their gazes toward the "Wangcai Sixth Child Model" instantly became incredibly heated, like a group of bachelors seeing a peerless beauty.

Dynamic optical invisibility!

This was a nightmare-level problem that had plagued the military industry for years!

The reason fighter jets can be invisible is that the airframe structure is fixed.

But if it's a variable-wing aircraft, or a flexible exoskeleton worn by a soldier, achieving optical invisibility is harder than reaching the sky.

Because as soon as you raise your hand or take a step, the creases in the clothing break the continuity of the light, exposing you instantly.

Yet now, this problem had actually been solved in a toy factory restroom by a robot dog holding toilet paper?

This was absolutely absurd, absurd to the extreme!

Liu Jianguo realized this as well.

He took a deep breath, suppressing the shock in his heart, and with his sharp eyes locked on Li Jiajun, he said in a deep voice:

"Little Li, don't give me that cheeky smile."

"Now, right now, immediately, make this dog run a few steps for me!"

"I want to see with my own eyes if it can really achieve dynamic invisibility!"

Although the old Expert's analysis was sound, hearing is believing, but seeing is truth.

Such disruptive technology must undergo the most rigorous verification.

Li Jiajun shrugged, looking helpless as if to say, "You guys really haven't seen much of the world."

"Fine, fine, fine, running a few steps is nothing."

He snapped his fingers at the transparent dog that was still acting cute for everyone and issued an order:

"Sixth Child, put on a show for the leaders."

"Activate invisibility mode, run from here to the sink, and then run back."

"Woof!"

A crisp, electronically synthesized dog bark came from the air.

The next second.

Under the intense gaze of dozens of eyes, the robot dog, which had originally presented a semi-transparent outline, suddenly blurred.

Immediately after.

It was like a drop of water merging into the ocean, or a puff of smoke dissipating in the wind.

It disappeared completely.

It wasn't the kind of camouflage where you could still see a faint shadow, but a true, complete disappearance.

Its body seemed to have become part of the air, perfectly replicating the tiled wall behind it, the non-slip floor tiles, and even the angle of the light shining in through the window was perfectly restored.

"It moved! It moved!"

Someone exclaimed.

Although they couldn't see the dog, everyone could hear the sound.

"Tap, tap, tap..."

That was the slight sound of mechanical feet stepping on the tiled floor.

The sound moved extremely fast, instantly traveling from the stall entrance to the sink five meters away.

Everyone hurriedly turned to look.

They saw nothing unusual in the air in front of the sink.

However, the infrared sensor on the motion-activated faucet above the sink suddenly lit up.

"Whoosh..."

Water automatically gushed out.

Even though there was no one there, the faucet had been triggered!

"It's there!"

The old Expert excitedly pointed at the void below the water stream.

Immediately after, the sound quickly returned.

"Tap, tap, tap..."

Accompanied by a flurry of rapid footsteps, the dust on the ground was kicked up, forming an eerie trail.

There was nothing but the kicked-up dust in that space, yet the dog's shadow was completely invisible!

There wasn't even a trace of light distortion!

It was running at high speed, its limbs flailing wildly, its torso heaving, but all of this was perfectly covered by that magical coating and algorithm.

Until the sound stopped again at Li Jiajun's feet.

Li Jiajun reached out and patted the void beside him.

"Whimper..."

A comfortable whimper came from the air, as if an invisible dog was enjoying its master's petting.

This scene was extremely eerie and extremely shocking.

The scene was deathly silent.

All the Experts stood frozen on the spot, as if under a paralysis spell.

Their brains were trembling, and their worldviews were collapsing.

It was... really done.

Dynamic optical invisibility.

In this restroom filled with the smell of toilet cleaner, a Mount Everest of human materials science and optics had been crossed so easily.

"Hoo... hoo..."

Liu Jianguo's breathing became heavy.

He looked at the "air" beside Li Jiajun, his head buzzing.

He had originally thought that today's surprises—or scares—would end with the "armed robot."

He didn't expect this kid to still be hiding such a trump card!

How is this a robot dog?

This is clearly the future king of single-soldier infiltration! It's the ultimate weapon for special operations!

If this technology were used on soldiers' combat uniforms...

Liu Jianguo didn't dare to think about it.

He turned his head sharply, staring fixedly at Li Jiajun, his finger trembling as he pointed at the void, his tone full of questioning, even tinged with a hint of anger at his lack of ambition:

"Li Jiajun!"

"You kid... you hid an upgraded version of the invisibility coating technology?!"

"Such important technology, and you didn't say anything? You actually... you actually used it on a dog?!"

This is simply a waste of a precious resource!

Li Jiajun looked incredibly aggrieved.

He spread his hands and blinked innocently, his expression like a child wrongly accused by their parents of stealing candy.

"I'm wrongly accused, Uncle Liu!"

"How did I hide it?"

Li Jiajun pointed at the "Sixth Child" beside him and explained righteously:

"I'm just solving a user pain point!"

"Think about it, this dog is placed in the restroom to hand toilet paper to people who run out."

"When people are using the restroom, that's such a private moment, right? If there's a big iron dog squatting next to you, staring at you with two glowing blue electronic eyes, watching you poop."

"How weird would that feel? How awkward? Would you even be able to go?"

Li Jiajun sighed and continued:

"So, to protect the user's privacy, I just conveniently made it invisible."

"This way, since everyone can't see it, there's no pressure, right? And they can release themselves to their heart's content, right?"

"My design is completely out of humanistic care!"

Hearing this, Liu Jianguo felt his chest tighten, a mouthful of old blood stuck in his throat, unable to spit it out or swallow it.

Just so people wouldn't feel awkward pooping?

So you solved the world-class dynamic invisibility problem?

How exactly is your brain wired?!

However, it wasn't over yet.

Li Jiajun looked at everyone's "I've seen a ghost" expression, and a thought suddenly occurred to him.

He looked at Liu Jianguo with some confusion, then at the top Experts from the Weaponry Industry Group, and cautiously asked a question.

The lethality of this question was ten thousand times greater than that of the invisible dog.

"Um... Uncle Liu, leaders."

Li Jiajun blinked his eyes, his tone innocent and confused:

"Don't tell me... you took the previous technology, but still can't use it on objects that can deform?"

Pfft!

This knife stabbed too hard.

It was basically a white blade in, red blade out, with a handful of salt sprinkled on top.

The atmosphere at the scene instantly changed from shock to extreme awkwardness.

Those Experts who were originally ecstatic about discovering new technology now had faces flushed like liver, wishing they could crawl into a crack in the ground.

It was too heartbreaking.

Li Jiajun's previous coating technology that could achieve optical and radar invisibility had indeed been requisitioned.

Relevant scientists had been working tirelessly to apply it to the latest stealth fighter jets.

However, as Li Jiajun said, this coating requires a stable physical state to achieve optical invisibility; if the object's state changes, optical invisibility cannot be achieved.

It can be used on fighter jets because the large surface area of the jet is skin that doesn't undergo drastic changes.

But it cannot be placed on deformable items, such as soldiers' clothing or variable-sweep wing aircraft.

Relevant personnel had researched it for a long time, their hair balding, but they still couldn't maintain optical invisibility when the object deformed.

This was their current bottleneck, their pain point.

And now.

This hurdle they couldn't cross no matter what.

Was effortlessly crossed by Li Jiajun, this "toy factory director," for the bizarre reason of "not making it awkward for a dog to hand over paper."

And he even asked them in return: "You guys haven't figured it out yet?"

Who the hell can handle that!

This is not just a technological crushing, but a dimensionality reduction strike on intelligence!

The old optical Expert clutched his chest, feeling like he was about to have a heart attack.

He had spent his whole life doing optical research, but today he felt like he had lived all these decades in vain—and it was on an invisible dog, no less.

Liu Jianguo looked at this scene, at the ashamed Experts, and then at the innocent-looking Li Jiajun.

He took a deep breath and closed his eyes.

He was exhausted.

Damn it, this kid clearly solved such a big problem, but why does he feel so terrible?

He felt that this kid was born to be their nemesis.
