Indeed, although Ye Han had successfully mastered the Thunder Escape Technique, he had not cultivated any Thunder Element Cultivation Techniques, which meant that casting Thunder Element Spells consumed an especially large amount of his spell power.
His successive kills of three Foundation Establishment Realm Cultivators might have looked effortless, but in reality, he had unleashed his Thunder Element Spells at full strength. His other spells had consumed less than a tenth of his spell power.
The Thunder Escape Technique alone had consumed eighty percent of his spell power. Even Thunder Lightning had used comparatively little.
Thus, while the Thunder Escape Technique was formidable, its spell power consumption was terrifying. Repeated use would quickly drain him dry. Fortunately, the Purple Cauldron had stored enough spell power energy to support his use of the technique.
Still, this expenditure was far too great. The energy stored in the Purple Cauldron that could replenish his spell power did not appear out of thin air. It had to absorb pills to replenish its reserves.
