That was to say, after acquiring Dark Magic Energy, Yang Mu could unleash thousands of attacks equivalent to Third Order spells.
However, Magic Energy was not without flaws. First, it had an upper limit. A type of Magic Energy could not grow without end; the growth limit of the low-grade Dark Magic Energy Yang Mu had created was the peak of the Third Order.
When first created, the Dark Magic Energy was roughly equivalent to the weakest Third Order spell. Yet through cultivating it, its power could be raised to the level of the strongest Third Order spells.
