Chapter 176: The Sea Snake Murder Case

“Stop waving your hands!”

Fujino, who had withdrawn his gaze, immediately stood up and shouted to everyone, “Ms. Toda is drowning!”

“What?!”

Everyone present was stunned by the news.

They clearly found it hard to believe that Toda Kiwako would drown.

But recalling her behavior just now, they had no choice but to believe it.

“Kiwako!”

Matsuzaki Masahiko, who had recovered, was the first to shout and rush out.

“Wait! Masahiko, you can’t swim!”

Then, the four members of the university freediving club who were with him followed closely, rushing towards the beach together.

Seeing that several people had rushed out, Ran also stood up and followed almost simultaneously with Conan.

Fujino, seeing this, didn’t idly stand by and immediately followed suit.

…

It was high tide in the afternoon, and the originally calm sea was turbulent, with ocean currents carrying the sea breeze, stirring up waves.

Soon, the group arrived beside the drowning Toda Kiwako.

After learning she was drowning, Matsuzaki Masahiko, who was the first to rush forward, was knocked down by a wave, and being unable to swim, he choked on the seawater and coughed dryly.

“Did you forget you can’t swim?!”

Ito Yo quickly arrived, grabbed Matsuzaki Masahiko, and threw him behind him.

Then, he quickly reached Toda Kiwako’s side, grabbed her jaw, and pulled her towards the shore.

“Kiwako!”

“Calm down!”

Everyone rushed forward to check the situation.

“That shouldn’t be…”

Fujino, who was observing the seawater that only reached his chest, frowned slightly.

Such shallow seawater, only reaching his chest.

Even if Toda Kiwako wasn’t as tall as him, she shouldn’t have been submerged up to her head…

It might be possible for an ordinary person in a panic.

But Toda Kiwako was a member of the freediving club, and her swimming skills were far superior to ordinary people.

How could someone who could free dive drown in such a shallow area?

Did her leg cramp?

Just as Fujino was collecting his thoughts, intending to return to the shore with the others, a system notification suddenly sounded in his ear: “A new detective profession quest has been detected. Please check.”

Fujino opened the system quest interface, and a system light screen appeared before him:

[Detective Profession Quest: Sea Snake Murder Case

Quest Objective: Solve this case

Quest Reward: One million Japanese Yen, one hundred Detective Reputation

Quest Time Limit: Three hours]

“It’s not that simple after all, huh?”

Fujino looked at the system interface before him, then turned his gaze to Toda Kiwako. “A sea snake?”

If it was a sea snake, then that sea snake should still be nearby.

Capturing that sea snake would mean possessing crucial evidence.

It must be said, a sea snake is indeed a very clever tool for committing a crime.

One bite, and half a life is gone on the spot.

Release it back into the sea, and the physical evidence is gone.

Closing the system interface, Fujino activated his visual enhancement glasses and began searching for the sea snake mentioned in the system quest title.

Soon, he saw a black shadow flash by in the surging sea.

Although it was only for less than one or two seconds, he confirmed the direction in which the sea snake had fled.

Taking a deep breath, he dived into the water.

It was a long, strip-shaped creature, seemingly with two transparent wings on its head—a sea snake.

The sea snake’s body continuously swayed, swimming at an extremely fast speed, against the ocean current, towards the depths of the sea.

“How could something like this be here?”

Fujino caught up with the sea snake, grabbed it, and observed the two transparent white wings, his mind filled with thoughts.

…

“Where’s Masahiko?”

On the other side, Toda Kiwako, who had been carried towards the shore by Ito Yo, coughed twice and, in a daze, softly asked.

“Masahiko is right over there.”

Ito Yo teased, “After he found out you were drowning, he was the first to rush into the sea without regard for himself. Now he’s completely soaked.”

“That’s good…”

She hadn’t finished her sentence before her eyes closed.

“Alright, your wife is entrusted to you.”

Ito Yo handed her over to Matsuzaki Masahiko. “She just drowned; it shouldn’t be anything serious.”

“Yes, yes, you don’t have to worry too much.”

Kawazu Kunio echoed, “I think she just had a leg cramp.”

“I knew I shouldn’t have let her come free diving…”

Matsuzaki Masahiko complained as he took Toda Kiwako.

“Strange, where’s Senior Fujino?”

At this moment, Ran, who had returned with the others, noticed something was wrong.

She turned her head and looked around but couldn’t find Fujino’s trace.

“He was clearly around here just now.”

Conan, hearing this, also looked around.

“Could it be…”

Ran showed a worried expression, “Did Senior drown too?!”

Conan turned his head to look at the turbulent sea, his brows furrowed.

He remembered Fujino swimming quite fast just now, so how could he drown?

Was it also because of a leg cramp?

That wasn’t impossible.

Under cramps, all are equal. Even a professional athlete, if they cramp in the sea, would at least be in serious trouble.

Thinking of this, Conan immediately panicked and shouted to Ran, “Ran-neechan, quickly go look for Fujino! He might have drowned too!”

Although that guy Fujino often teased him, he couldn’t let that guy die now.

He still wanted to use his superb deduction to properly interrogate that guy who always bullied him!

“Senior Fujino seems to…”

Just as Ran was about to ask for help from the others, a loud shout came from behind: “Don’t move!!”

“Huh?”

“Plop!”

Everyone turned their heads at the sound and saw Fujino emerge from the sea like a fish leaping over a dragon gate, waving a black, constantly wriggling, strip-shaped object in his hand.

This scene greatly resembled Fujino disturbing the sea.

“Whew…”

Fujino took a deep breath, alleviating the dizziness caused by lack of oxygen, then waved the sea snake he was holding by the head. “I just found this sea snake nearby. Ms. Toda might have been bitten by a sea snake.”

“A sea snake?!”

At this moment, everyone noticed the black, yellow-spotted, long, strip-shaped sea snake in Fujino’s hand, wriggling grotesquely like a super gluten man.

“Fujino, you…”

Conan looked at Fujino in surprise, wanting to speak but holding back.

How long did this guy dive?

And he even caught a sea snake!

Sea snakes can swim at speeds of up to twenty kilometers per hour in the water.

Human swimming speed is at most five kilometers per hour.

Not to mention freediving.

He remembered that it had been about four minutes since he last saw Fujino.

Could this guy have been freediving for four minutes?

Is this something a human can do?

Indeed, it was not something a human could do.

He had held his breath underwater for three minutes to catch this sea snake.
