So it's not that it's slow, but rather that large swathes of sand dunes move along with it.
The speed is probably astonishingly fast!
As everyone was feeling uneasy, it suddenly disappeared from the mirror.
Gone?
Where did it go?
Everyone fell silent, and the sand sea in the mirror was quiet as well.
It felt as if a nerve was taut.
Stretched to...
Knock!
"!!!"
Everyone looked at the door, their hearts trembling, as if goosebumps were crawling over their skin.
The door was closed.
Someone was knocking on it.
There was one knock, then nothing.
Everyone had different expressions, on guard together, but before they could react...
It was gone.
When they thought it was truly gone.
Knock knock knock!
Several slow knocks in succession.
This was more than just scary.
Everyone stood up with swords drawn, and there was sound from outside.
"Is anyone there, is anyone there?"
The voice was soft and raspy, weak, like a kind old lady gently speaking to a child.
