Finally the explanation and im quite satisfied with it :) i hope that after this without that necklace absorbing his negative energy, mc can finally be right on track. But you say the seal can only be broken with enough negative energy, so mc barely got enough negative energy after being tortured or something? What would have happened if the necklace broke but mc didn't have enough negative energy?
???? Demon lord needing negative endrgy? I'm down with that. The system selfishly taking the negative energy of its host (aka parts of its host) and saying you need to be worthy, annoying but acceptable. The so called system that the demon lord used, fine. But what I can't get past is the system needing money and the dumbass not questioning it. Like, add explanations. The system is just a visual interface, the so called stats are just representations of your state and the stat points added give you access to/unlocks a small portion of my powers. And the armours, weapons and accessories you see are all mine that I stored in my (only accessible to me) storage/in my soul. And the money needed to buy that is merely for the emotional value you humans put on it.
