If

[What if a soul that shouldn't have been there appeared in the Marvel Universe...]

2012, New York, Midtown Manhattan.

Inside an ordinary two-story apartment of about 500 square meters on Fifth Avenue.

A handsome chestnut-haired boy of about 14 or 15 was alone, using chalk to draw something on the oak floor of his bedroom.

The boy wore a casual white shirt. He was tall with refined, sharp features and wore half-rimmed gold-framed glasses.

Sunlight filtered through the blinds, casting mottled shadows across his profile, which, combined with the cozy interior, gave off a quiet and refreshing vibe.

Except for...

The clearly mismatched black mechanical right arm protruding from under his sleeve, which was emitting a faint "creak" as he drew.

Yet, compared to the noisy mechanical arm, the circles the boy was sketching on the floor—resembling some sort of evil ritual—seemed even more out of place in the surroundings.

"Hmm, that should be about right. Now for the materials!"

He tossed the chalk aside, not waiting for the boy to make another move.

From the living room downstairs, the voices of a middle-aged man and woman arguing in hushed tones drifted up.

"Gina! You should have at least discussed this with me beforehand! We already left Sokovia and escaped those people! And now you want to go and actively seek a partnership!"

"You are practically pushing this company into a pit of fire!"

As he spoke, the middle-aged man was trying his best to suppress his tone, yet he couldn't hide his current anger.

In contrast, the mature and beautiful middle-aged woman opposite him spoke in an exceptionally calm and cold tone.

"Herman, times have changed. These days, you can't make a steady profit just by relying on one or two inventions and a few patents."

"I can wait, but will the shareholders wait for you?"

"We've lost orders from Stark Industries and Hammer Industries one after another. If we don't make changes soon, the company won't be able to survive."

"I don't care what you think. Even if it's just for Luca's future quality of life, I must save this company!"

Hearing his wife's resolute words, the middle-aged man named Herman opened his mouth several times, but not knowing how to refute her, he could only argue his point stubbornly.

Although the argument downstairs grew louder, to the point where it was impossible to ignore, the boy in the bedroom upstairs merely shook his head helplessly, having no intention of going down to intervene.

It wasn't that the boy was cold or didn't care about family harmony.

It was just that, having transmigrated to this world not long ago and spent nearly two months in the hospital, he couldn't quite sort out his current family relationships.

Luca von Orange.

His original name no longer mattered.

In his previous life, after assisting the police in taking down a large-scale fraud syndicate, he was hit head-on by a fully loaded gravel truck on his way home.

The last thing he saw before death was that truck, which might have been there to retaliate against him, crashing relentlessly into an apartment building by the roadside.

When he opened his eyes again, Luca had transmigrated into this boy who had also died in a car accident.

Perhaps the God of Transmigration had worked his magic, or perhaps Luca's soul had nourished this body.

After several days of emergency treatment, although he lost his entire right arm below the elbow, the body had ultimately pulled through.

Now, nearly two months later, as his memories gradually merged, Luca, who had been a loner in his past life, slowly accepted this new family with both parents and a wealthy background.

At least in this world, I still have a happy family, don't I?

Since arriving in this world, Luca had always comforted himself this way.

However, compared to this happy family, the world itself was not so "wonderful."

During his two months of hospitalization, besides merging his memories, the few things Luca could do were watch television in his room.

And that billionaire who wore his flashy armor to fight crime around the world every day was naturally the most frequent news figure on TV.

Having watched plenty of Marvel movies in his past life, Luca naturally understood what kind of world he was in.

It was just that the Marvel Universe was famous for its numerous parallel worlds, so he wasn't sure if the future would unfold exactly as he remembered.

Fortunately, as far as the public was aware, Iron Man was the only active superhero, so the world hadn't yet turned into a place where ordinary people couldn't survive.

Of course, another reason Luca could temporarily set his mind at ease was...

Having transmigrated, he also possessed his own cheat!

Looking at the circle on the floor that looked like an evil ritual, Luca took an ordinary pair of red sneakers from the box beside him.

However, to Luca's eyes, these sneakers—which looked unremarkable to anyone else—not only emitted a faint white light, but as he held them, a pale blue text panel appeared above them.

<strong>[Power-Enhancing Shoes]</strong>

[Friendly Reminder: These shoes feature durability, breathability, and anti-odor properties, personally verified by a certain detective who hasn't changed his shoes in 30 years~]

Yes, this was the golden finger Luca had obtained after transmigrating.

Luca, who had spent nearly two months lying in a hospital bed, had tried every method to awaken a "system," an "old grandfather," or anything of the sort, but all had failed.

This led him to believe he had no golden finger at all and would have to struggle for survival relying solely on his limited foresight of the Marvel world.

Who would have thought that after returning home from the hospital, he would discover that a pencil case "he" had once used was emitting a faint glow visible only to him.

Upon touching the pencil case, a chaotic stream of information including "Origin World," "Manufacturer," and "Synthesis Materials" had all popped up.

As for the item from the One Punch Man world called the [Pencil Missile], Luca had already synthesized it two days ago using a series of inexplicable items like "pencils," "gunpowder," "glue," and "firearm grips."

As for these [Power-Enhancing Shoes], they were the second synthesizable item Luca had discovered, taken from a pair of ordinary sneakers in a regular shoe store.

Luca had not yet fully grasped the various capabilities of this golden finger.

For instance, what did the "1/5" after "Detective Conan World" mean?

Why did patterns resembling "magic circles" pop up in his mind after touching a "core component"?

Why, after drawing the same "magic circle" a second time, was he unable to manufacture new [Pencil Missiles] using the same brand of pencil case and materials?

But at the very least, he had roughly figured out the most basic "synthesis" function.

He placed the red-and-white sneakers in the center of the circular array, with the other items arranged in their corresponding smaller circles.

These items, which were originally just ordinary materials, immediately began to emit a faint glow similar to that of the red-and-white sneakers, which were referred to as the "core component."

"Hmm? Are 5-volt batteries no good? Are small military-grade storage batteries no good either?"

He tried several batteries in succession, and it wasn't until he placed a common button cell battery bought from a supermarket into the array that the white glow finally enveloped it.

"Ugh, can a button cell that can't even power a vibrating toy really drive these Power-Enhancing Shoes?"

Quickly shaking off the stray thoughts in his mind, Luca pressed both hands onto the edge of the circular array and silently chanted in his heart.

"Synthesize!"

Immediately, a golden light surged, completely swallowing the entire array.

By the time the light dissipated, all the other materials in the array had vanished, leaving only a brand-new pair of red-and-white sneakers in the center.

However...

"Why did these shoes shrink so much?"

Looking at the red-and-white sneakers that were barely larger than his palms, Luca felt speechless.

"Could it be that these Power-Enhancing Shoes are only for elementary school students?"

As he spoke, Luca reached out and picked up the sneakers, which were clearly several sizes smaller than before.

To his surprise, the moment he touched them, they seemed to possess a sensory function; they immediately expanded, appearing to be exactly his usual size.

"This..."

Luca examined them closely. The shoes were seamless, and apart from a white dial on the outer side of the right shoe, they were indistinguishable from ordinary sneakers.

Even inside the shoes, there was no sign of batteries, wires, or electric shock pads.

If not for that spontaneous change in size just now, one would think that without the synthesis panel, these red-and-white sneakers were just a pair of ordinary shoes.

After a moment of hesitation, Luca decided against taking the shoes apart to inspect them.

He had previously extracted two "missiles" from the [Pencil Missile] to keep for later, hoping to see if he could disassemble and replicate something similar.

But these shoes were a single, integrated piece, and they were notoriously "black technology" that defied logic. If he were to tear them apart blindly, his own pathetic theoretical knowledge and manual skills would certainly never be able to put them back together.

It was better to just put them on and test their effectiveness.

"That said, normally speaking, kicking something with these wouldn't break my foot, would it?"

Thinking this, Luca used his somewhat clumsy mechanical right hand to quickly put on the shoes.

"It's a pity that only the right shoe has the power adjustment dial; using my right hand normally is a hassle as it is."

"If only I could come across some kind of black-tech arm or something later."

Feeling the inconvenience of his right hand, Luca tried moving his feet before standing up.

Just as he was wondering whether to tell his parents he was going downstairs to find something to kick, a series of sharp, whistling sounds suddenly came from outside the window.

With a puzzled expression, Luca hurried to the bedroom window to look out.

Then, he saw it.

In the distance, a blue beam of light shot straight into the sky, and at the very top of that beam, the sky seemed to have been torn open into a massive hole.

Countless aliens in armor riding flying crafts poured out from that hole, then began to wreak havoc across New York.

Even worse, biological warships over a hundred meters long, resembling the Leviathans of myth, cruised through the air and dove downward, smashing through building after building.

On the ground, people were screaming in panic and calling for help, while beams of light fired from alien weapons rained down like droplets, triggering a series of explosions.

The entirety of New York seemed to have descended into a living hell.

All these sights converged into a single answer.

"The Chitauri, they've invaded!"
