Sam reached near enough to be in the visible range of the Sea folk that are guarding the bubble.
The Sea folks looked at Sam and they became a bit restless. It has been decades since aby human or elf came this deep into the sea.
The guards here are actually pretty lax because of that.
But now they already learned of someone causing trouble to them in shallow waters and their watchers are all gone. There is an anomaly the previous night and now there is a human coming towards them.
Three Sea folks swam towards Sam with water spears forming their hands. They are extremely fast. Sam aimed his harpoon gun and pulled the trigger.
The harpoon left the gun with the large wind jet blasting it forward and it impaled itself into the sea folk that is in the front.
The sea folks are obviously not as thick as a beast and their bodies are more or less the same sizes as a normal human.
