The rain started without warning.
One moment the streets of the city were loud with traffic and neon lights. The next moment clouds rolled in like a dark curtain and the sky opened.
People rushed under shop roofs.
Motorbikes slowed.
Street dogs disappeared into alleys.
But inside a tiny electronics repair shop, Aarav didn't notice the rain at all.
His attention was locked onto the computer screen in front of him.
Green lines of code scrolled down slowly.
Then stopped.
"Come on… work," he muttered.
The old computer fan whirred loudly, struggling like an exhausted machine that had seen too many nights of use.
Aarav leaned back in his chair.
The shop smelled of solder, burnt wires, and instant noodles. Tools were scattered everywhere—screwdrivers, circuit boards, phone screens waiting to be repaired.
He had inherited the shop from his uncle two years ago.
It wasn't a glamorous job.
Most days he fixed broken charging ports and cracked displays.
But sometimes…
Sometimes he hacked things he probably shouldn't.
A soft ping interrupted his thoughts.
A new message appeared on the screen.
Unknown Network Connection.
Aarav frowned.
"That's strange."
His shop's internet router had been disconnected hours ago. He had done that intentionally so he could test a private system without interference.
Yet somehow…
The computer had connected to something.
He opened the terminal window.
Lines of encrypted text appeared.
Then, slowly, a single message formed.
HELLO, AARAV.
His fingers froze above the keyboard.
"No way."
No one knew this system was running.
He quickly typed.
Who are you?
The reply came instantly.
Someone who needs your help.
Aarav's mind raced.
This wasn't a normal hacker. The connection protocol looked unfamiliar. The signal seemed to be coming from inside the city network—but not from any visible server.
He typed again.
How did you access my system?
A pause.
Then a new message appeared.
Because you were the only one who could see the signal.
Aarav leaned closer to the screen.
"What signal?"
The computer speakers suddenly crackled.
For a second the monitor flickered.
And then an image appeared.
It looked like a map.
A digital map of the city.
But beneath the normal streets…
Another set of lines appeared.
Hidden tunnels.
Dozens of them.
Running under the entire city.
Aarav stared at the screen.
"What… is this?"
The message appeared again.
The real city.
Lightning flashed outside the shop window.
The power flickered.
Then the final message appeared.
They are coming for me.
If you want the truth… come to Tunnel 17.
And just like that…
The connection disappeared.
The screen went black.
For several seconds Aarav sat completely still.
His heart was beating faster now.
Most people would ignore something like this.
Most people would shut down the computer and go home.
But Aarav wasn't most people.
He grabbed his jacket.
Locked the shop.
And stepped into the rain.
Because somewhere beneath the city…
A secret network of tunnels existed.
And someone inside those tunnels had chosen him.
