Chapter 665: Unexpected benefit

Seeing they were concentrating on recovering their mana, he thought, 'I should be done recovering bloodline energy and mana by the time they finish.'

Thinking this, he closed his eyes and started absorbing the mana out of the mana crystal, absorbing, refining, and converting it into the bloodline energy.

Ba-Dum!

Ba-Dum!!

As he recovered more and more bloodline energy, his heart rate started increasing, albeit slowly, and his breathing also turned a little heavier.

Initially, he thought it was the result of him recovering bloodline energy through mana multiple times, but when he paid attention, his expression hardened because...

…this change was caused by the devil blood in his heart, which had absorbed quite a bit of demon energy when he helped the Fullers.

'Wait…'

Suddenly, he noticed something and arched his eyebrows.
