The blood dispersed in the sea during the battle with the Sea turtle would attract other magical beasts, Noah was sure of it.
'It's a pity that the Blood drain spell is only up to the second rank, killing rank 4 beasts is quite easy now.'
The Blood drain spell had helped Noah in shortening the amount of time required for his body to reach the fourth rank, he held in high regard the mechanism behind such spell.
'Transforming the blood of an enemy into nourishment for my own body, that sound precisely like a magical beast. It's a pity, I can't use it since my level is too high and I don't even have a body-nourishing method to absorb the energy gathered in that way.'
The Yin body was a rank 4 body-nourishing method, it had brought Noah to the peak of the lower tier of the fourth rank but now it couldn't be used anymore.
The Yin body was formed, Noah needed a stronger nourishing method if he wanted to resume training his body.
