Innate Supreme Treasure

Northern Black Tortoise Immortal Domain, Nether Capital.

Nearly half of the Demon Race had gathered in the Northern Black Tortoise Immortal Domain. Nether Capital was the Demon Race's sacred land, and every year, all the great Demon Immortal magnates would come here at set times to pay homage to Northern Imperator, the supreme Great Luo Golden Immortal of the Demon Race.

Here, the Immortal Domain Gate was not built in the starry sky. Instead, it had been built directly at the very edge of Nether Capital.

It looked less like an Immortal Domain Gate and more like Nether Capital's city gate.

It had originally been the Maritime Trade Office harbor of Nether Capital in the ancient era. The ancient stone tower still stood there, as if it were still guiding ships across the Nether Sea.

Nether Capital itself was an ancient-style grotto-heaven with a round sky and a square earth, rather than the star grotto-heavens that were popular in the various Immortal Domains nowadays.

Looking out, one could see the bright moon hanging in the grotto-heaven's interior, lanterns layered throughout the city, and endless Immortal palaces and towers. One Immortal Island after another drifted across the sea of clouds beneath the night. There were no clear skies or bright days here, only a tranquil moonlight.

At this moment, the various Great Heavenly Demon tribes, divine beast inheritances, and Aristocratic Clans of Demon Immortals had all arrived in Nether Capital. They knelt before the Nether Palace, waiting for an audience with Lord of Nether Capital, Northern Imperator.

Beneath the palace gates and before the steps, the vast auras of Golden Immortals and True Immortals surged into the heavens, filling the azure void. Outside Nether Capital, densely packed star Daoist Temples of grotto-heaven and blessed-land grades were moored before the Immortal Domain
