Within the Xuan Realm, there are several special Immortal Materials, which are essential Divine Gold for the Sacrificial Refinement of Emperor Weapons.
Dark Immortal Gold is one of them, highlighting its preciousness!
Others include Fiery Sun Red Gold, Moonlight White Gold, Dragon Pattern Azure Gold, Qilin Purple Gold, and so on.
These materials are things even a Great Emperor would crave; throughout the history of the Xuan Realm, not every Great Emperor has been able to find these Immortal Golds for the Sacrificial Refinement of Emperor Weapons.
Especially since the power of Emperor Weapons is too immense, aside from these top-grade materials, other metals simply can't withstand the pressure of a Great Emperor, let alone be used to refine Emperor Weapons.
