The veil of darkness surrounding him vanished, the tendrils of Asura corruption receding from his mind, body, and soul. John fell into Lilian's embrace, nearly overwhelmed by the exhaustion and pain he felt.
Had it not been for the blood of the Yang-Sovereign that he drank, his wounds would not have healed as much as they did, and his body would have been completely devoid of energy. Even still, many of his wounds still persisted, the damage to his body far too great for him to heal though his innate healing ability alone.
Only Laia would have a chance of healing his body into a working condition, and even then, it was doubtful she could heal him in less than several weeks at the very least. As for the underlying damage that lurked deep within his body, only time could heal those wounds.
