The Devils Killer (1)

Klaus chose the Lava Tail Mountain Lion as his first target. As its name suggests, the creature's tail is its deadliest weapon, shaped like a blade capable of slicing through metal with a single swipe. 

Ten years ago, the Overlords could have easily wiped out all five Fire Devils that roamed the Devil's Abode. But they left them untouched, setting a challenge rather for anyone brave enough to take them down.

A reward was promised, though no one knew what it was. Dozens of warriors entered, but none returned. Over time, people gave up on the idea of venturing into the Devil's Abode, not only because of the danger but also because the area lacked any real resources. Eventually, the place became deserted.

That was exactly why Klaus picked it. He wanted to push his skills to their absolute limit without risking the life of another warrior. Here, it was just him and the monsters lurking in the infernal lava pool.
