The myriad heavens and domains each once had their proper place.
China's immortal mountains and seas of clouds, the rise and fall of dynasties, the heroic spirit of Liangshan Marsh, and the Star Gang descending to the mortal realm; the Immortal-Slaying Formation of Investiture of the Gods and the contest for the sacred way. In the West, the sacred flames of Olympus and the thunder of Asgard; in Egypt, pyramids slumbering through the ages; in India, the eternal chants of Brahma. Countless other dimensional worlds held youths with swords, flames that could scorch the heavens, martial arts and supernatural abilities side by side, miracles and technology existing together.
For billions of years, the multiverse coexisted in endless conflict, yet continued to thrive.
Until one day, the "Sovereign of Unity" used the foundation of his own Dao to pluck the strings of time and space, enacting the "Law of the One": all laws would be melted together, all living beings brought into order, every difference erased, and all the heavens fused into a single world.
The crash of collapsing planes resounded through the river of time. Immortal palaces collided with pyramids; marshlands and ice fields melted into one domain; battle aura and chakra became the same primordial essence. Countless souls were extinguished, countless civilizations vanished, and the survivors fell into the same shattered land: the Melting Firmament Realm.
The divine power of the mighty was sealed, and emperors fell into the dust. Divine generals, kings, heroes, and strange beasts were all branded and shackled by the order, with less than one-tenth of their peak strength remaining. Those who resisted were crushed, those who saw the truth were imprisoned, those who submitted became numb "servants of order," and those who rebelled were refined into the Banner of Ten Thousand Souls.
The seventy-two Earthly Fiend altars and thirty-six Heavenly Gang altars were like one hundred and eight poisoned nails driven into every inch of the Melting Firmament Realm, drawing out the essence of living souls day and night to feed the Sovereign of Unity, sleeping deep in the Central Province. The day the altars sound as one will mark the silence of all life and the beginning of eternal uniformity.
