"That's right." Melyne nodded and said: "Darkness Space—that is where dark monsters are kept. Even though that place is very dangerous and mysterious, it also has a huge use for someone like you who possesses the Dark Swordsman talent."
"According to what is recorded in ancient documents, anyone with a talent that has the element of darkness in it can enter Darkness Space."
"There is not much information about the people entering that space. However, there is one thing we can be sure of, and that is…"
"You can absorb the dark energy of the dark monsters you kill."
Hearing that, Harris thought of something and said: "You mean... I can level up by killing monsters?"
He immediately realised this was because, on this continent, killing people or monsters to level up was not uncommon.
However, those who leveled up by killing like that were all subordinates of the Demon Lord.
