Primordial Demon God of the Primordial Period!
No matter which Demon God it is, they are absolutely the most powerful and terrifying existence at the peak between heaven and earth.
For example, the King of Primordial Chaos is actually one of the Demon Gods born during the Primordial Period.
There is also the Ancestor of the Dragon Clan in the Dragon Realm! The Demon Ancestor in the Demon Domain! The Hell Master! The Ancient Heavenly Emperor! And so on.
The strength of the bloodline power of these Demon God experts goes without saying.
However, these Demon God experts rarely have descendants; the King of Primordial Chaos, the Demon Ancestor of the Demon Domain, the Hell Master, and the Ancient Heavenly Emperor all have no descendants.
The current Heaven Emperor is just a direct disciple of the Ancient Heavenly Emperor.
