Levi sat at the side and ate his roasted meat as he spoke indifferently, "Believe me, if killing you can make Fred better, I will kill you ten thousand times."

The burly man cursed, "You sure have big words. You despicable scoundrel who used poison."

"Didn't I learn this from you, scum?" Levi said.

"I swear on the Heavenly Father that I, Iron Mountain, have been an assassin for many years, but I've never used poison. Although I'm an assassin, I'm also a knight, and I yearn for a fair battle, unlike you," cursed Iron Mountain.

Levi mocked, "You're already an assassin, don't pretend to be a noble here. No proper knight will be an assassin? Judging from your breathing technique, it should be of excellent quality. Could you be the illegitimate son of some earl?"

He did not know his simple words would hit Iron Mountain's sore spot.
