Deep within the darkness, a ferocious pair of eyes glanced at the intruders vigilantly before entering into the night again, as if it was never there in the first place.
The intruders, who didn't seem to notice anything, stealthily walked through the only available path confidently.
But suddenly, several metal bars shot out from the ground behind them, sealing the hallway entrance they used to step in.
Just beside the door meant for visitors to enter was a hallway on the side that led to where they were now.
And now, their only exit point that they planned to use after finishing the mission was shut!
The metal bars revealed themselves like Wolverine's claws and completely sealed the place, followed by another set of metal bars that layered the first set.
Bam!
Everyone leaped and turned around to see what the sound was.
They were startled, alright?
Only those at the very back saw the whole thing.
