The Mysterious Power Rebelled

The only problem now was that he was very hungry. He was still a human after all, though he possessed a fighting power befitting a God.

When the two energies tried to heal Ryan's body, suddenly the mysterious power in his body started to rebel again.

The power seemed to reject the arrival of the new ones. Hence, it attacked the two energies in an attempt to destroy them.

By this time, Ryan was almost completely conscious. He could feel his body getting better and he was very happy. But when his mysterious, aggressive power attacked the energy that was trying to help him recover, his heart clenched again.

Why was his mysterious power acting like that?
