Because it's due to the Energy Avatar, without sufficient spiritual power, there's naturally no way to gather a large amount of Energy. Thus, the more massive the spiritual power, the stronger the Energy Avatar that Zhou Tian distributes will be. Hence, when Zhou Tian's spiritual power becomes strong enough, theoretically, Divine Descent could become one of Zhou Tian's significant Attack Methods in the future; it's not impossible.
And at that moment, without mentioning other things, at least if Divine Descent uses Faith Power as one of its Energy sources, then this Ability will undoubtedly become much more powerful.
As long as a small amount of spiritual power is used as the core, mobilizing a large amount of Faith Power as a vassal, the spiritual power initially only tenfold can exert a hundredfold strength. Under such circumstances, Divine Descent can be continuously perfected, and the effect of Faith Power will become greater.
