"Thud, thud, thud..."
A deep and eerie sound accompanied by some sharp screams seeped through the iron walls beside him, causing Colin to instinctively look up, his expression immediately one of alarm.
Outside a thick, round glass window, a large school of fish were swimming and frolicking under the light.
Beyond the light, everything was murky and dark, countless tiny objects floating in the ink-green water, and amidst the dullness, there were faint, sharp, and strange sounds emanating.
Even Colin felt an inexplicable fear in this airtight and narrow room.
This place is...
"The deep sea?"
Colin quickly stood up, using the room's frequently flickering lights to discern that the space was probably a cramped rest area hardly four square meters in size.
The rest area was riddled with rust, as if it had been soaked in water.
Colin took a deep breath and roughly analyzed the situation, confirming that there was nothing else in the room except for himself.
