The moment that Samuel began refining the energy, he noticed that the energy contained within the golden light was being depleted at a rapid pace. Samuel was not sure about the reason, but he could guess that maybe, to be able to reach the next level, he would have to consume a huge amount of energy.
Time ticked by, and a little while later, it had already been 30 minutes since he began refining the energy. And, within those 30 minutes, only around 20% of the total amount of energy that was initially contained within the golden light was remaining.
This was way faster as compared to before, considering that it had taken Samuel more than 2 hours in order to refine just about 10% of the total amount of energy that he had previously.
But Samuel could not help but frown when he noticed that the energy was being depleted, but his level was not changing at all. Just what amount of energy was required for him to be able to reach the next level?
