Rio's consciousness blurred, and he found himself back in the same dimly lit basement hall as he was before.
"Didn't expect this to be so mentally demanding…"
A severe headache assaulted Rio the very moment he returned back to his senses and regained control over his own body.
His mental power was not like mana and miasma that he could just easily grow with random training methods.
Even if he were an anomaly and generally unaffected by mental and spiritual corruption, he would still feel fatigued if his mental power became weaker from continuous use.
'This is the first time I have ever run out of mind capacity and soul power…'
'When I head into the demon continent, I will have to harvest some souls with fairly intact consciousnesses to use them to strengthen my mind and soul by a vast margin…'
Rio had done the same thing in the spirit realm, but back then he didn't have much time to waste, and he had carried out the entire mission in a hurry.
