"Rest assured that what you've comprehended from the ocean's surface just now is beneficial," said the guard to the two, giving them a reassuring smile.
"However, as someone who has dived into the ocean a few times already, let me tell you now that the insights you've obtained from looking at the ocean's surface will be overshadowed the moment you dive in."
Seeing the confusion that was slowly appearing on the duo's faces, the guard let out a slight chuckle before giving them an explanation regarding the ocean's workings.
"Though the Ocean of Crystallized Truths is a place known for its ability to aid in the comprehension of concepts, the layer where you decide to comprehend your concepts affect both the quantity and the quality of the insights you obtain in the end."
Gesturing the number five with his fingers, the man continued, "The ocean has five layers in total."
"In terms of how much you'd benefit staying there, it goes Surface, Shallows, Depths, Abyss, and Core."
