Sean was holding the flashlight and entering deeper into the dark cave, feeling a little uneasy.
Although he didn't have claustrophobia, it was impossible not to feel uneasy in this narrow space where he couldn't see clearly in front of or behind him.
However, with so much debt on his shoulders and the stimulating buff of searching for pirate treasure, Sean gritted his teeth and continued to dive deeper.
After a short while, though, the passage in front of him seemed to begin ascending.
On both sides of the cave walls, there were obvious traces of artificial excavation.
About a minute later, Sean's head suddenly broke the surface of the water — it was gone.
Sean tried taking off his breathing mouthpiece, and discovered that there was actually air in this place!
He guessed that he had reached a space below the island.
As for the air, it was probably seeping in through the gaps in the rocks.
He shined his flashlight upward, but saw nothing.
