Coroner: A Detective Conan Fanfiction

While everyone else was focused on Ran Mouri, Lin Xinyi was watching Ishikawa.

More precisely, he was examining the injuries on Ishikawa's chest—and the dented wall behind him.

"This kind of injury…"

"If someone told me he got hit by a car, I'd believe it!"

"How is this possible? Is this really a level of strength that humans can possess?"

At that moment, Lin Xinyi's entire worldview was shaken to its core.

After all, he had an extremely thorough understanding of the human body.

Strength, at its essence, was just the tension and contraction force generated by muscles.

For humans, more muscle mass, greater weight, and a larger muscle cross-section typically meant greater strength.

In his previous life, Lin Xinyi had been highly skilled in combat, but in terms of raw strength, he could only claim to be among the top in his own weight class.

When he transmigrated into the body of this "Security Director," who had a similar build to his own yet possessed even greater strength, he had already been somewhat surprised.

So humans could actually be trained to surpass their limits.

But clearly, he had been shocked too early.

Just look at this Miss Ran Mouri—

She was fair-skinned, slender, with delicate limbs, looking every bit like a featherweight martial arts enthusiast.

Yet this featherweight had just unleashed a force that even a sumo wrestler couldn't muster.

If humans could inflict trauma comparable to a traffic accident with their bare hands, then had all those medical textbooks he read been lies?

Lin Xinyi's expression remained focused, but inside, he was frantically questioning reality.

"Uh… Mr. Lin Xinyi?"

His prolonged contemplation caught Shinichi Kudo's attention.

In the past, whenever Lin Xinyi made that face, he always managed to notice details that others had overlooked.

So naturally, Shinichi couldn't wait to ask, "Did you find something?"

"Hm?" Hearing this, Ran Mouri also turned to look at him curiously.

"…Yes."

Still lost in shock, Lin Xinyi blurted out an impolite question:

"Kudo, is your girlfriend really human?"

"…"

A brief silence.

Then, simultaneously, Shinichi Kudo and Ran Mouri's faces turned red.

In perfect unison, they retorted:

"She's not my girlfriend!"

"I'm not his girlfriend!"

"…"

Another silence.

Then—

"Hmph!"

They exchanged a glance before turning their heads away from each other in perfect sync.

"…"

Lin Xinyi was speechless.

They were practically glued to each other, acting all lovey-dovey, yet they weren't a couple?

What was with all this unnecessary restraint? Even someone who had only known them for half a day could see they were flirting!

Wait—no!

He was getting sidetracked.

Was that really the important part here?!

Someone, please explain this physically impossible strength!

His mind was overflowing with question marks and exclamation points.

His eyes, filled with intense curiosity, were now locked onto Ran Mouri's legs.

"Smooth skin, graceful curves, no prominent gastrocnemius or soleus muscles."

"They look just like a celebrity's legs…"

"How the hell does she generate that kind of power?! This makes no sense!"

As he stared at those delicate legs that shattered his understanding, Lin Xinyi fell into deep thought.

And the atmosphere started turning a little weird.

Ran Mouri, feeling his gaze, blushed and looked slightly uncomfortable.

Shinichi Kudo, on the other hand, reacted like a cat whose tail had been stepped on—his eyes filled with sudden wariness.

Even the usually indifferent Shiho Miyano leaned in slightly, her voice carrying a playful, mischievous lilt as she whispered in Lin Xinyi's ear:

"You really want to touch Miss Ran's legs, don't you?"

"Of course."

Lin Xinyi instinctively replied,

"The most direct way to assess muscle density is through palpation."

"But it would be even better to dissect and examine them. If I could directly observe the muscle fiber structure and extract samples for microscopic analysis, I might be able to—"

Ran Mouri: "…"

Shinichi Kudo: "…"

Shiho Miyano: "…"

Now even Shiho was convinced that Lin Xinyi was more of a mad scientist than she was.

"Ahem."

Realizing his slip, Lin Xinyi forcibly calmed himself.

Then, he cautiously asked,

"Miss Ran Mouri, were you born this strong?"

"No," Ran Mouri finally understood what he had been fixating on. "It's all from training."

"Karate can make someone this powerful?"

Lin Xinyi found it hard to believe.

He had studied various martial arts in his previous life, including karate.

No martial art in the world could turn a person into a superhuman. If anyone claimed otherwise, they were a fraud.

That included his own ancestors.

His family's martial arts manual boasted of legendary feats—flying across rooftops like a swallow, reshaping one's skeletal structure, fighting lions and tigers barehanded, lifting mountains with ease…

According to the manual, if he mastered these techniques, he should be able to go toe-to-toe with Captain America.

But after training since childhood, all he got was… better street-fighting skills.

Once he became a forensic scientist and learned about human anatomy, he dismissed those claims even more.

Yet now, standing before him was a real, scientifically impossible superhuman.

"Of course karate can reach this level!"

Ran Mouri, thinking he was doubting karate's effectiveness, responded earnestly,

"If you train consistently for years, your strength will naturally surpass ordinary people."

"And there are plenty of karate practitioners at my level—not just me."

"Oh, by the way, Mr. Lin, I saw you in action earlier…"

"You must have a deep understanding of combat, right?"

"Tomorrow is the Tokyo Karate Tournament. All the top young fighters from the city will be there."

"If you're interested, you should come watch!"

She smiled modestly and added,

"With my current skill level, I'm not sure how well I'll rank."

"…"

Lin Xinyi fell silent.

So people as strong as her weren't even rare?

And this was just a Tokyo karate competition?

If he expanded the scope to include the entire world's martial artists, then wouldn't this planet be crawling with mini-Supermen?

Back in his previous life, he had reached the pinnacle of martial arts.

Yet now, even a high school girl practicing karate was displaying strength far beyond his.

Clearly, something was very wrong with this world.

For the first time, Lin Xinyi truly grasped the reality of his situation:

At first, he had thought he had merely traveled back in time to old Japan.

But now, it seemed like he wasn't in his original world at all.

The Earth he came from followed the laws of science—Newton wouldn't be rolling in his grave every other day.

But this Earth?

It was clearly a low-level martial arts fantasy world.

He had just jumped from the "Modern Life" channel to the "Supernatural Martial Arts" channel.

"A world where 'superhumans' exist, huh?"

Suddenly, Lin Xinyi felt an intense interest in this bizarre reality.

Like many boys, he had once dreamed of a world where martial artists could defy gravity and perform legendary feats.

And to be honest—he was a martial arts genius.

Born into a martial arts family, he had started training at five, learned boxing at six, and mastered his family's techniques by seven.

By eight, his elders had praised him, saying:

"If he had been born three or four centuries earlier, he could have founded his own school of martial arts."

(Though that same elder used this as an excuse to cut his New Year's money in half.)

At ten, he joined a karate class.

One month later, the instructor tearfully refunded him three times the tuition fee and begged him to leave.

At thirteen, he defeated ten gang members in a street fight, injuring six, scaring off three, and making one pee his pants.

That was the end of his "martial arts career."

But now—

Looking at this world filled with supernatural fighters, Lin Xinyi's passion for martial arts reignited.

"If a high school girl can become this strong through training…"

"Then if I train in this world, I can definitely surpass human limits!"

And more importantly—

"If this world defies science…"

"Then maybe my family's 'nonsensical' martial arts manuals… are actually real?"
