On the deck of the White Dolphin in the Weddell Sea.
Ye Yuan gazed at the endless expanse of floating ice in the distance.
He felt uneasy.
He did not know whether it was merely his imagination.
But he kept feeling that some enormous creature had its eye on his fishing vessel.
Yet he had carefully searched the surrounding area with his perception.
He had found no suspicious creatures nearby.
Given his current level of Mental Power,
Ye Yuan did not believe anything could silently evade his sensory detection.
He stared at the dark purple seawater visible beneath the ice.
Any experienced fisherman would know
that the waters in this area had reached a certain depth.
Ye Yuan had not determined this through his perception.
It was simply common knowledge among people who made their living at sea.
There was a certain relationship
between the color of seawater and its depth.
Generally speaking, as the water grew deeper,
its color gradually darkened as well.
In shallow-water areas, seawater usually appeared lighter in color,
such as light blue or green.
That was because, in shallow water, light could penetrate the sea more easily.
There was more scattered and reflected light,
making the seawater appear brighter.
Once the seawater reached a certain depth,
more of the blue light in sunlight would be absorbed.
As a result, the other colors of light were relatively less absorbed.
Therefore, seawater in deep-sea regions often appeared dark blue or deep purple.
In addition, suspended matter in the seawater, living organisms, dissolved substances, and so on
could also affect its color.
As Ye Yuan stared blankly at the water,
he heard a concerned voice behind him.
"Are you all right?"
Ye Yuan did not need to turn around to know who the voice belonged to.
"I'm fine.
