"The normal Spiritual Energy Cannon operates like this."
"I see, Uncle, how many Spirit Stones does it take to activate this Spiritual Energy Cannon once?" Ji Yuan asked curiously.
Yun Wannian stroked his beard and laughed, "The Spiritual Energy Cannon has three levels of attack: the first level has the lowest attack, similar to a late-stage Foundation Establishment cultivator's full force strike. It estimates that one activation needs 80 Mid-grade Spirit Stones."
"The second level is equivalent to the peak of Foundation Establishment cultivator's full strike, and one activation requires 300 Spirit Stones."
"The third level is comparable to a full force strike from an early-stage Golden Core cultivator. Activating the third level... requires at least 900 Mid-grade Spirit Stones."
