The world of mortals was filled with very interesting things, and one was level advancement. From high races to lower races, from humanoid being to beasts, one thing they relished in was advancement in levels. There could be factors that differentiated one from the rest; be it bloodline, lineage, Path, wealth, talent, resources etc. But ultimately, the level advancement was what they relished in more. Starting from the Novice Level to the Saint Realm for intelligent races or from Bronze Rank to the Sacred Realm for beasts.
Advancement in levels came with a lot of advantages for one. From the Novice Level or Bronze Rank to the Grandmaster Level or Supreme Rank, advancement was pretty simple and straightforward. Train, cultivate, break your limits and level up. Pretty simple. There were variables like Ethan and Trevor who could just breakthrough like it was nothing, even skipping some levels.
