Kapitel 564: Cap 562: Rescuing the Blood Demons part 3

After telling Vanessa to take care of the enemies outside I enter the tower, outside I wasn't able to use my Aura unless I tried more rudely, but I didn't do that so I wouldn't risk attracting a powerful Undead by chance. 

I always have to be very careful as with my luck the chances of bad things happening are quite high. 

As soon as I entered my Aura was separated from the outside, that means I could now spread my Aura all over this place while being unable to feel the outside. 

After a few seconds, a real-time image of this entire place pops up inside my head. 

"So there are only 4 people, but the 3rd seems to be the one I'm looking for." (I) 

"< Blood Crystallization >" (I) 

I could see everything perfectly inside my head, that means I could use my Enhanced Crystallized Blood Needles to hit my targets with precision.
