In the Heavenly Emperor Palace of the Jun family, Jun Xiaoyao was sitting in one of the secret training rooms with his legs crossed.
The room was filled with all kinds of top-tier divine sources that emanated boundless, thick spirit qi.
Common fighters in the mystic realm trained using common types of source stones.
Cultivators of some top-notch orthodoxies and cultivation forces would be using celestial sources, which were more precious than the common variants.
Only members of the Clan of the Ancients, Wushang Orthodoxies, and Undying Dynasties have access to the most precious of cultivation sources: the divine sources.
The best of such sources —the mystic sources— lied above the divine sources, yet they were so exceedingly rare that not even the Clans of the Ancients had many of them stocked.
Regardless of their rarity, all source stones were divided into four tiers: low, middle, top, and supreme.
