After a clicking sound, a hole appeared in the wall. He exhaled; it seemed indeed that no one had come for a long time.
"Number!"
"DOMO73895." The man announced a string of numbers in a rather unskilled tone and stepped back half a foot. With a clang, the wall split open to reveal a door, or rather, a gap just large enough for one person to pass.
He went inside, but got stuck midway. The mongrel tilted its head with curiosity, whimpering at the sight of his round figure squeezing through with difficulty.
Once he was entirely inside, the mongrel began to bark sharply. Its only response was another clang, followed by a piece of bone thrown out of the hole in the wall. It looked somewhat like a small leg bone. The milky-yellow shaft was still attached to bloody flesh chunks, very fresh and very gross.
But the mongrel didn't think so. It happily picked up the bone that fell into the puddle, wagging its tail, and ran off into the darkness.
