This seems quite a bit too convenient. I could overlook it in the beginning, but its getting a bit out of hand at this point with the spirit looking at the cards and him soloing a 34 person boss after only a week of training. Hes stacked with OP abilities, yet that isn't even enough. Frankly, his abilities are too OP to write around. He can literally train eternally so long as he doesn't rank up by killing monsters.
