Of course, the spell power consumed by the Heaven-Deriving Art was also determined by the number of tiers and meridians. When they exerted power simultaneously, they consumed power simultaneously as well. If one meridian used too much and ran out of spell power first, the Heaven-Deriving Art could no longer be used. Thus, if I wanted to use it, I had to ensure that all my meridians maintained a balance of spell power. I couldn't drain one completely before using another. Otherwise, if I activated the Heaven-Deriving Art but couldn't actually use it, I would be like a clever housewife facing an empty rice jar—unable to cook a meal.
