The shadow beneath the door didn't move.
Neither did Kai.
Silence.
A suffocating silence.
Kai slowly backed away from the entrance.
The office wasn't large.
One desk.
Several shelves filled with rotting folders.
A toppled cabinet.
No windows.
No second exit.
"...Great."
He whispered.
"I'm trapped."
Squelch.
The shadow beneath the door shifted.
Something heavy pressed against the other side.
The rusted doorknob slowly turned.
Kai instinctively grabbed the nearest object.
A broken metal pipe.
"...Please don't come in..."
The door creaked open.
Just a little.
A thick yellow substance squeezed through the gap.
Not flowing.
Stretching.
Like it was forcing itself through a hole far too small.
Kai stared in disbelief.
"...It can do that?"
The slime slowly reformed inside the room.
Its body expanded.
Broken glass.
Metal scraps.
Old bones.
Everything suspended inside the translucent mass floated lazily.
Then...
It stopped.
The slime quivered.
Kai held his breath.
"...Maybe it can't see..."
The slime suddenly lunged.
"Oh, COME ON!"
Kai threw the metal pipe.
It disappeared into the creature with barely a splash.
The slime continued forward.
Kai shoved the cabinet.
It crashed over.
The slime simply flowed around it.
He ran.
The creature blocked the doorway.
