The Frontier City's City Lord

"This is quite satisfying to watch" seeing waves of beasts just falling down on the ground with their bodies acting like water in the sea, the immortal-like young man couldn't help but nod in satisfaction to his job, not to mention the massive amount of Heaven Devouring Power stored inside his body currently.

Feeling the surging power continuously refining, transforming and improving his entire being, he starts harvesting other beast's lives as well, within a few swings leaving nothing but dust behind.

"I can still improve it…" if the him from the previous timeline were to hear what he is talking about, the immortal-like young man will definitely be berated by himself from there, an extremely powerful expert whose ability reach the very pinnacle, yet still somehow unable to improve the technique given that it seems to be already a technique of the highest quality.
