The message stayed on the screen.

Three simple words.

Stop the experiment.

Amara stared at Daniel’s phone, her mind struggling to process what she was seeing.

“Is this a joke?” she asked slowly.

Daniel shook his head.

“I don’t think so.”

He checked the message details again, scrolling slightly.

“Unknown number. No name attached.”

Amara felt a chill crawl down her spine.

Someone had sent that message knowing exactly what they were doing.

And more importantly… knowing about the experiment.

“How would someone even get your number?” she asked.

Daniel slipped the phone back into his pocket.

“A lot of people have it. Classmates. Lab assistants. Friends.”

“That’s not reassuring.”

He gave a small shrug.

“Welcome to university life.”

Amara sighed and leaned against the lab table, running a hand through her hair.

The situation was becoming more unsettling by the minute.

First the system error.

Then the strange bacterial growth.

Now a threatening message.

None of it felt like coincidence.

Daniel watched her quietly.

“You’re thinking too hard.”

She shot him a look.

“Someone is literally telling us to stop our research. Of course I’m thinking.”

“Fair point.”

He walked toward the incubator and looked at the culture plates again.

“If someone wanted to scare us, they’re doing a pretty good job.”

Amara crossed her arms.

“Do you think it’s someone from our department?”

Daniel considered the question.

“Maybe.”

“But why would anyone sabotage a student research project?”

“That depends,” he replied.

“On what?”

“On whether this is really just a student project.”

Amara frowned.

“What do you mean by that?”

Daniel didn’t answer immediately.

Instead, he picked up a lab notebook and flipped through the pages slowly.

“Your research topic,” he said finally. “Antibiotic resistance.”

“Yes.”

“That’s not exactly a small topic.”

Amara’s eyebrows narrowed slightly.

“It’s an academic study.”

“True,” he said. “But antibiotic resistance research can attract attention.”

Her confusion deepened.

“From who?”

Daniel closed the notebook and placed it back on the table.

“Pharmaceutical companies. Research institutions. Even private labs.”

Amara blinked.

“You think someone is interfering because of the topic?”

“I’m saying it’s possible.”

The thought made her stomach tighten.

She had chosen the topic because it was scientifically important, not because she expected it to cause problems.

Daniel noticed the worry on her face.

“Hey,” he said more gently. “We don’t know anything yet. It could still be a prank.”

“A very elaborate prank,” she muttered.

Silence filled the lab again.

The quiet hum of equipment seemed louder now.

Amara looked around the room carefully.

For the first time since starting the project, the laboratory no longer felt like a safe place.

Daniel noticed her uneasy glance.

“You okay?”

“I’m fine.”

“You don’t look fine.”

She sighed.

“I just hate feeling like someone is messing with my work.”

Daniel nodded slowly.

“I understand that.”

Amara looked at him, surprised by his tone.

“You do?”

“More than you think.”

Something about the way he said it made her curious.

“What does that mean?”

But Daniel simply shook his head.

“Nothing important.”

Amara studied him carefully.

He was hiding something.

She could feel it.

But before she could question him further, a sudden sound made both of them turn toward the laboratory door.

A faint metallic clink echoed from the hallway.

Daniel frowned.

“Did you hear that?”

Amara nodded.

They both moved toward the door cautiously.

Daniel opened it slowly.

The hallway outside was dim and empty.

But as they stepped out, Amara noticed something on the floor near the doorway.

“Wait,” she said quietly.

She bent down and picked it up.

It was a small flash drive.

Daniel looked surprised.

“That wasn’t there earlier.”

Amara turned the object over in her hand.

There was no label.

No markings.

Just a plain black flash drive.

“Do you think someone dropped it?” Daniel asked.

“Or left it,” Amara replied.

They exchanged a glance.

Both were thinking the same thing.

Daniel gestured toward the computer inside the lab.

“Well… there’s only one way to find out what’s on it.”

Amara hesitated.

“What if it’s a virus?”

“Then we’ll use the lab computer’s security system.”

She walked back inside slowly, her curiosity growing stronger.

Daniel followed closely behind.

Amara inserted the flash drive into the computer.

For a moment, nothing happened.

Then a folder appeared on the screen.

Daniel leaned closer.

“What does it say?”

Amara clicked the folder open.

Inside was only one file.

A video file.

Daniel frowned.

“That’s strange.”

Amara clicked the file.

The screen went black for a second.

Then the video began playing.

A figure appeared on the screen.

But the person’s face was hidden in shadow.

Amara felt her heartbeat speed up.

The voice that spoke next was distorted.

“If you’re watching this, it means you ignored the warning.”

Daniel’s posture stiffened.

Amara stared at the screen.

“Your experiment is more dangerous than you realize,” the voice continued.

“You are studying something that others have already tried to control.”

Amara felt a wave of confusion.

Control what?

The voice continued.

“Stop the experiment while you still can.”

The video suddenly cut to static.

Then the screen went black again.

Neither Amara nor Daniel moved for several seconds.

Finally, Daniel spoke.

“Well…”

Amara slowly turned toward him.

“That definitely wasn’t a prank.”

He nodded.

“Not even close.”

Her thoughts raced.

Someone clearly knew about their research.

Someone who didn’t want them to continue.

And whoever it was had gone through a lot of effort to deliver that message.

Amara closed the video window slowly.

Her voice was quiet but determined.

“I’m not stopping the experiment.”

Daniel raised an eyebrow.

“You’re not even a little scared?”

She looked at him firmly.

“Of course I’m scared.”

“Then why keep going?”

Amara folded her arms.

“Because if someone is trying this hard to stop us…”

She glanced back at the incubator where the bacterial cultures were growing.

“…then we must be close to discovering something important.”

Daniel stared at her for a moment.

Then a slow smile appeared on his face.

“You know something?”

“What?”

“I think this project just became a lot more interesting.”

But neither of them noticed the small red light blinking on the laboratory security camera.

Someone else was watching.

And they had just heard everything.
