The Moro Time Tower activated by Divine Crystals indeed has a better effect.
Back in the low-class world, Jing Yan didn't use the Moro Time Tower often, mainly because the energy consumption was too high. Moreover, during the few times he used the tower, Jing Yan only activated it with top-grade Spirit Stones.
Jing Yan simply couldn't bring himself to use Divine Crystals to activate the Moro Time Tower.
It wasn't until he reached the God Realm, obtained many Divine Crystals, and coupled the rewards from the ranking competition and Qingmu Department—adding up to a full seven hundred thousand Divine Crystals—that Jing Yan didn't mind consuming some. This also led Jing Yan to the surprising discovery that the Moro Time Tower's ability to alter the flow of time is not fixed. Top-grade Spirit Stones can accelerate the time flow in a specific area by five times, while First-Level Divine Crystals achieve ten times.
