Nightmare Dragon Blood

The essence blood of a Nightmare Dragon, a仙界 (Immortal Realm) existence comparable to the Ancestral Dragon and the ancestor of the True Dragon Clan’s mortal enemies, the Devil Dragons. It contains immense Nightmare Dragon true essence but is tainted with chaotic power. For others, forcibly refining it can pollute their法力 (magical power) and turn them into a projection of the Nightmare Dragon. The True Dragon Clan has methods to slowly refine it, though most true essence is lost in the process.
