On the Jiuzhou Continent, treasures are categorized by their quality.

Heaven, Earth, Mystic, and Yellow!

Whether it's Mystic Artifacts, Mystic Skills, pills, Talismans, or Mystic Materials, they are all classified into these four grades, with some items further divided into upper and lower grades.

For example, the battle blade in Jiang Han's hand is a Mystic Rank Mystic Artifact, and the Mystic Skill he practices, "Sevenfold Blade," is Earth Rank. The Xuan Ling Pill, on the other hand, is Yellow Rank.
