Not long after, Zhang Yao finished tending to the Spirit Field, reclined on a lounge chair, and started reviewing several high-level Skills recorded in the "Thick Earth Spell."
Unlike external items such as Spirit Pills, Magical Artifacts, and Talismans, magic in the world is only divided into low-level and high-level, with differences lying not in power but in Mana Attribute.
Low-level skills are unrestricted by mana attributes, but mana of the same attribute provides a bonus; high-level skills, however, must correspond to the mana attribute, and even match the Cultivation Technique to be practiced.
Take the "Thick Earth Spell" in his hands as an example:
There are five high-level skills paired with the Cultivation Technique, four of which require late-stage Qi Refining earth attribute mana; the strongest, the "Earth Soul Armor Skill," cannot be practiced by anyone except cultivators of the "Thick Earth Spell."
