Within the Nine Heavens of Primordial Chaos,
if one were to ask which Celestial Domain had the most races,
then Heaven-Burning Fire, where the Human Race and Alien Species coexisted, would undoubtedly top the list.
Tens of millions of years ago, the Mountain and Sea and the Human Race tore up their treaty. The two races went to war, and the Fourth Tribulation erupted, affecting all of Hongyuan's Heavenly Realms and the Ten Thousand Races.
War is not a matter of black and white.
There were factions within the Human Race that betrayed them and joined the Mountain and Sea Alien Species, just as there were Alien Species who stood in solidarity with the Human Race.
For example,
the Demon Race of All Heavens—long denigrated as 'mongrels' by the Innate Wilderness Clan of the Mountain and Sea—was the one to put aside their prejudices at that time. They turned their allegiance to the Human Race and joined the attack on the Mountain and Sea Realm.
