The Heavenly Demons have five levels: the Black Sky Demon with Supreme Realm combat power, the Red Sky Demon with Reincarnation Realm Sovereign strength, the Purple Sky Demon with Nirvana Realm Sovereign strength, the Silver Sky Demon with Life and Death Realm Sovereign strength, and the completely unknown Golden Sky Demon — the Supreme Sky Demon.
The Silver Sky Demon that formed the Heavenly Dao Alliance is the most powerful existence in the Heavenly Demon clan, aside from the Supreme Sky Demon.
According to the information provided by Elizabeth and Tiger, this Silver Sky Demon has at least the strength of a Life and Death Realm Sovereign at Great Perfection. It is probably just a step away from evolving into a Golden Sky Demon. Otherwise, it wouldn't have the foundation to resist the Golden Sky Demon along with other Heavenly Demons.
