9:28 a.m.
Special Investigation Division. Data Analysis Room.

No windows.

Only screens.

The light was cold.
The room was quiet.
The air felt sealed.

Tan Chih Lin sat at the center.

Didn’t look up.

Fingers moving.

Fast.

Silent.

“Begin.”

Screens lit up.

Not one.

Sixteen.

Four victims.

Four lines.

Four worlds.

Lin Bing.
Hong Yu.
Tan Xin Yi.
Su Mei Mei.

“Surface data—”

Tan said.

“No issues.”

Display shift.

Grades.
Courses.
Social logs.
Spending patterns.

“Normal.”

Shift again.

“Deep data.”

Pause.

The screens split.

Overlapping courses.

Shared projects.

Intersecting timelines.

Lines—

began to form.

Not one.

Many.

A web.

“You see it,” Tan said.

No one answered.

They all saw.

This was not coincidence.

This was—

structure.

Chang stepped closer.

“Explain.”

Tan zoomed in.

“Here.”

Different times.

Different locations.

Same system.

“BETA.”

The word again.

The air dropped.

“Just a project?” Lee asked.

Tan shook his head.

“Not a project.”

Pause.

“A platform.”

The interface expanded.

Code.

Access points.

Hidden pathways.

“This is a backdoor.”

“They weren’t users.”

“They were—entry points.”

Silence.

“Entry to what?” Yim Bing asked.

Tan didn’t answer.

He opened another layer.

The data changed.

Not people.

Flows.

City data.

Traffic.

Communications.

Location grids.

Even—

public systems.

“They’re using them—”

Tan said quietly.

“To touch the city.”

The room went still.

“Meaning?” Lee asked.

“Testing.”

“Testing what?”

“Control.”

No one spoke.

The screens kept moving.

“Their behavior—recorded.”

“Their responses—analyzed.”

“Their neural reactions—triggered.”

Chang’s eyes darkened.

“The scent.”

Tan nodded.

“That’s the input.”

Pause.

“The human body—”

“is the terminal.”

The air turned cold.

Yong Tin Kei spoke.

“Output?”

Tan stopped.

Then:

“Not complete yet.”

A blade of silence.

“They’re still testing.”

“So there will be more,” Chang said.

“Not more.”

Tan stared at the data.

“An upgrade.”

New data appeared.

Release frequency—rising.

Intervals—shortening.

Concentration—adjusting.

“They’re tuning it,” Yim Bing said.

“Yes.”

“Like training.”

“Training what?” Lee asked.

Tan didn’t look at him.

“A system.”

“One that can—”

He paused.

“control people.”

Silence.

“Scale?” Yong asked.

Tan pulled up a map.

Dots.

One.

Two.

Four.

Then—

more.

“They’re not just testing targets anymore.”

“They’re spreading.”

The city lit up.

Like a net.

Everyone understood.

This was no longer a case.

This was—

infiltration.

Chang said quietly:

“The watcher—”

“Is not a person,” Tan said.

“It’s a system.”

Pause.

“Or—”

He looked up.

“The people behind it.”

Yong stood.

His shadow cut across the screen.

“Find the source.”

“Not the person.”

“The system.”

“I want to know—”

“who is writing this code.”

The lights stayed cold.

The screens kept flickering.

The web—

was becoming visible.

And now they knew—

They weren’t hunting a killer.

They were facing—

something that was learning.
