'However, because of this realm's mechanisms, we still must absorb it.'
Atlas could feel that the small amount of energy inside of him was trying to act as a compass. It was "pointing" at something in the distance, most likely a treasure.
'By coming closer to death, your performance in a realm of death improves.'
This was obvious enough.
'Then, the core concept of this realm is merely gambling.'
Everyone's body would have a different tolerance to the energy of death. Ingesting it was a complete gamble.
'To a point, you can sense when it is becoming too much.'
However, perhaps it was better to take the risk and ingest more if it meant finding better treasures.
Such was the conundrum that the Ascenders in this realm had to face. As Atlas had only killed a single beast thus far, he wasn't to the point where he was considering the risks. He only acknowledged them as something that existed.
