Chapter 384: Whirlpool (8)
The water wasn’t exactly murky, but the view was still hazy—partly due to the lingering darkness of the sky, but mostly because of the water itself.
No, more accurately, it was definitely the water.
Human sight relies on light passing through the cornea, entering the pupil, traveling through the vitreous body, and landing on the retina.
For an image to be clear, the light must not be distorted—but underwater, refraction bends light, making it impossible for the retina to form a sharp image. That’s why vision becomes blurry underwater.
Didn’t we all learn back in grade school that light changes direction when it passes through substances with different optical properties?
That was it.
Glass, salt, diamond, water—they all refract light.
Which meant that because of the distortion, I couldn’t clearly make out what the thing in the water actually was.
But it’s not like I can’t see anything at all.
Still, would I have tried to identify the creature underwater if I had no way at all?
Even though the image was blurry, I had a method to roughly figure out what it was.
And that was: get closer. The farther away it was, the blurrier the image. The closer, the clearer.
