The outer edge of the magic circle lit up like a candle while the blood turned bright red, releasing a string of concentrated spiritual energy into Hao Xuan's body.
He shuddered in disbelief upon feeling the torrential energy coursing through his extremities.
Gudmunder slapped him on the shoulder, "It won't be as good as your innate energy but with this you outa be able to use a few superficial techniques without too much trouble. The magic circle will cannibalize itself for 7 minutes from the moment you first start using the energy, make sure to finish it before that."
Hao Xuan rubbed the tip of his fingers which tingled with spiritual energy, filling him up from the outside in.
He smiled thoughtfully, 'It's been so long I forgot what it felt like. The emptiness is becoming lighter and even if it is temporary, I feel a little more like myself again.'
But when he looked at the Hell Knight staring him down from afar, he knew this much would not be enough.
