Soldier Boy looked expectant. "How's it going, John? Found that giant piece of seafood yet?"
Homelander shook his head and sighed. "No, my eyes can only see through things within five hundred meters. Kailong must be somewhere deeper."
Slightly disappointed, Soldier Boy raised his eyebrows. "What's going on with you? If I remember right, those eyes of yours can even see Mars, can't they?"
Homelander was momentarily at a loss for words. Then his eyes lit up, and he suddenly asked, "Have you ever studied physics?"
"Is that the subject where you have to memorize the periodic table?" Soldier Boy looked bewildered. He had always felt that physics was a subject far removed from him.
Homelander rolled his eyes, somewhat speechless. Only after a long moment did he say, "No, what you're talking about should be called chemistry."
After scratching his head awkwardly, Soldier Boy argued stubbornly, "Same difference. Don't get hung up on the little details. Why are you asking?"
Homelander explained patiently, "Everything our eyes can see is, essentially, visible because 'light' enters our eyes. The retinas receive the light signals, and the brain forms an image."
"And Mars is in space. It reflects sunlight, which travels to Earth, so I can see it. Humans can also see it through astronomical telescopes."
"But the ocean is different from space. It absorbs most of the light. If my eyes hadn't been upgraded again, I probably couldn't even see five hundred meters down. Two hundred meters would already be the limit."
At this point, Soldier Boy more or less understood, and his expression turned admiring.
At the same time, he marveled inwardly that Homelander actually knew so much.
Clearly pleased with Soldier Boy's reaction, Homelander looked thoroughly smug. "People really do need to read more."
Soldier Boy naturally knew that
