@Molass I'm not talking about that oldie, I'm talking about the words spoken by first heavenly demon right there when MC mention the core of his black sword.
He became soft when he fell in-love so bad with Ryu So-Wol ( Blue Spirit). Still Cruel and heartless af as an enemy but he changed so much as a person/leader especially if you're one of his people. Well, he's not that evil like we think of him about what he's like in his first life. He's evil self manifested when his closest aid betrayed him because he fell in-love with a mere human and the reason why that human, So-Wol, died hundred years ago before his very eyes along with the Moon Vein clan.
@Book yup it really is...but that the exact word spoken by MC in MMM in the later chapter of novel after he killed that thing dragon or imigol...not sure but that part was in the ending part of Novel MMM..
