The danger posed by Demon Spirits from the Demon Realm to the human world has existed for ten thousand years.
It was precisely because of the threat of Demon Spirits that the Heavenly Master System was born.
In the continuous struggle against Demon Spirits, the Heavenly Master System was constantly refined and expanded, from apprentices just mastering Spiritual Power, to Heavenly Masters, to Great Heavenly Masters, to Heavenly Monarchs...
Until the emergence of the creators.
The first creator was born three thousand years ago!
It was precisely due to the existence of such top-tier beings that the battles between humans and Demon Spirits gradually switched from defense to offense.
And a thousand years ago, the Heavenly Master civilization reached its peak.
The Master of the Holy Sanctuary, the Twelve Creators!
Gods Mountain, Sea God Temple, Netherworld...
One by one, great Heavenly Master powers rose.
