Here are my thoughts: 1-Please donât make the AI system come into the novel too often(like once or twice/chapter would be fine for me) or it could be the most annoying part of the novel. 2-Please donât Make him so powerful that no one can realistically fight him 3-Please make other monsters strong too, monster fights sound awesome. 4-my pick is energy. depending on the rules of the world I think you could do a lot with it. like maybe he can make a wizards spells fizzle out before it gets to him, or makes the spell overcharge and blow up in the wizards face. Or he could sap the energy out of a whole town so that No one can cast spells.
Psychic, i get that i should be similiar to soul power(correct me if im wrong) . Slave contracts, puppet Master, thats the essence of evil dao! On the other hand, big boy has a lot of Blood, he should be Able to control other with that. Void look nice to... Well, do what you want, Just keep in mind that a Man of culture needs some "action" from time to time xd. 3h of human transformation, he did waste that.
