While Zatiel fought the drowsiness and maintained his focus in absorbing the blood and vitality of the Fiend Dragonborn, he frowned as he noticed something odd.
The condition of Dior's body was deteriorating too fast, and the Neo-Demon was not receiving nearly as much energy as he should.

'This entire dimension is like a beast capable of absorbing the energy of those who die. Even though the result would not be as good as having tubes extracting their blood energy and life force, it is still useful.' There was not much Zatiel could do, so he just focused on obtaining as much blood and vitality as he could from Dior before there was nothing left from him to drain.
