Lucifer’s Treachery

Hearing Lucifer's words, Envy let out a smirk. "Then you are sorely mistaken, and you shouldn't have taken the price in the first place. Because this would mean you need to cough up all of those lifespans you took and even provide us with some serious compensation," she said.

"What do you mean? I clearly granted her instant mastery over that swordsmanship. The only reason she lost to that man is because her natural physical fitness is not up to the standard of that swordsmanship. It's not about skill," Lucifer refuted.

"I know that," Envy responded, continuing, "But are you sure that the skill doesn't require any more training? What she has learned is not the entirety of that swordsmanship. It's just the tip of the iceberg. What she learned is just the basics, the sword techniques used to fight monsters. I presume she still hasn't learned the techniques used to deal with colossal monsters," said Envy.
