章節 575: Cap 573: Message to Demon Goddess Kalistos

The next day I was mentally exhausted, jobs that involve organization and planning are worse than simply doing things in practice with my own hands, plus I was already tired from everything that had happened the day before. 

My mind was swarming with things to think about, about the God Fragment, about the Blood Demons, about the Blood Seal technique I learned thanks to Goddess Selene, about the plan in action, about the negotiation I will have to do with a Goddess, etc. 

There were so many things on my mind to think about that I felt my head ready to explode at any moment, even though having the parallel thinking skill wasn't enough, that skill just meant I would be doubly mentally exhausted.
