After an hour, Ace left the sect library. He had already memorized all three spells in the jade scrolls and could now comprehend them independently. However, these spells had the same issue as the skills in Mortal Sky Heaven: they couldn't be used with Heavenly Spirit Qi.
But Ace had already discovered a loophole. He could use them with his Holy Twilight Spirit Qi, especially since the ascension spells could be learned by both martial and soul cultivators. These spells were all driven by laws, and very few had restrictions on the cultivation paths, making those particular spells extremely precious.
Moreover, the main cultivation heritage of the AIG Sect was of the Soul Path, which aligned with his Holy Twilight Spirit Qi, also of the Soul Path.
