From a False Primordial World to the End of Time

(The protagonist is carefree and not exactly a good person. This isn't a prehistoric setting, though it borrows some of its background. Later on, many characters with a Western fantasy feel will appear.)

Mighty beings created chaos, and ancient Demon Gods split the primordial world with their axes.

Sages of the Three Corpses, Sages of the Three Aspects, incense Sages, and all kinds of mighty beings of the primordial world fought without end, unaware that many terrifying entities beyond the heavens were watching them covetously.

Forbidden lands, ominous consciousnesses, dark restricted zones.

Eldritch things, decaying beings, terrifying Demon Gods.

Cosmic insect lairs, forgotten glaciers, and dead star seas.

The primordial world is beset by disaster. Can the Immortal Ancestor and Ancient Venerable, a Miracle Demon God, continue to protect the legacy left by his elder brother?

When the variables, constants, and anomalies stand side by side, can they withstand the assault of the three rulers of the Dark Restricted Zones?

The Eternal Era - the Immemorial Era - the Ancient Era - the Primordial Era

The Recent Past - the Dark Age - the Age of Declining Dharma - Ancient Times - the Modern Era...

How far into the ages will the Miracle Demon God survive?

It is all a mystery.
