The Holy Light Goddess was very weak.
Of course, this weakness was relative to the original Holy Light Goddess, and to the seven ugly monsters that were suppressing her.
Compared to humans, even to Qin Chu, who was a Hero, and to Shaye, who was a Demigod, the strength of the Holy Light Goddess remained undeniably powerful.
In the first week, Qin Chu was not eroded by the Evil God, so he did not receive the grace of the Holy Light Goddess.
In the second week, Qin Chu was somehow connected with the Holy Light Goddess through a certain bond.
During the Prince's mutation, when he encountered the evil corruption himself, the Holy Light Goddess had demonstrated her divine might several times to assist him in resisting.
However, the help she provided was in fact a depletion for the Holy Light Goddess herself.
It must be understood that the Holy Light Goddess was in a state of imprisonment, unable to restore her Divine Power, and each use reduced it a bit more.
