As we've read, the four noblewomen surrounding the MC cause the essence to increase abundantly, if we were to count it at 50 essence per day. This leads to an overpower dilemma, which I tried to prevent at the beginning of the fanfic's creation.
Solution :
1. Switch to an overall fury system, only gaining death essence from killing.
2. Increase the amount of essence for new inheritances.
3. Eliminate the system. This might make the MC's future skills illogical, beyond the MC's knowledge.
