As he spent more time on Floor 17, Zero began to adapt to the darkness and the unfamiliar environment. His senses became even more finely tuned, and he was able to move through the fog with ease. He could sense the monsters before they could even see him, and he was able to strike them down before they even knew he was there.
As he grew more accustomed to fighting in the dark, Zero began to explore more of Floor 17, delving deeper into the dark and foggy depths. He faced giant Vampire Bats with razor-sharp claws, giant scorpions with deadly venom, and even a giant serpent that could swallow him whole. But no matter what the monster was, Zero was able to defeat it with ease.
Anyway, Floor 17 was no joke with various monsters specializing in poison attacks. Zero would get poison now and then from such monsters. However, most poison would be frozen and expelled before it even goes into his body.
