Let's prepare myself before going to the training in the dungeon.
That's right. The purpose of this mission is not dungeon clearance. It's for training.
And my preparation is much harsher than probably the exploration itself. Because I'm purposely wasting my mana while resting.
What I'm doing is limiting my choice for the exploration. Will I be able to clear the dungeon with the limitation that I put on myself? I have to. A real life experience is what I need most right now.
Just training and sparring with the dragons or the giants won't be enough anymore. I have to limit myself and see if there are ways I can get out of any situation and hopefully I can break through the limit and increase my level.
I can just put a limit on myself in a safer environment. For example if it's just for sparring with the others. But that is too safe. I need extreme situation to grow stronger.
