The only way Duke can currently acquire the Power of Faith is through the Divine Statue of Light.
There's no way he can just move such a large statue, otherwise, the people from the Light Sect would be desperate to stop him, even if he is the so-called Child of Light.
If he returns to the Wizard Plane and can't find any other method to acquire the Power of Faith, he'll have to wait another six months to return to the Oracle Plane, which is relatively restrictive.
Duke then prayed once more, and after establishing communication with the Divine Statue of Light, he received a sliver of the Power of Faith.
He calculated simply that at this rate, it would take about half a month to fully charge the energy of the Coordinates Earring again.
If he could stay here and pray continuously, the speed would be even faster, but that would seem too suspicious.
