I Just Attained the Dao as the Chaos Celestial Emperor, and You Want Me to Turn Myself into a Forbidden Zone?

Transported to a fantasy world and blessed with a Chaos Physique from the start, Lu Qingyun fought for eight hundred years and attained the Dao as the Chaos Celestial Emperor!

But just as he was about to establish an Immortal Court and suppress the Dark Forbidden Zones for hundreds of thousands of years, a system arrived-and its very first demand was for Lu Qingyun to turn himself into a forbidden zone.

He scoffed at the idea!

As the mighty Chaos Celestial Emperor, still at the height of my power, why would I need to hide in a forbidden zone and cling to life?!

[Ding-! Host detected to be nearing the end of his lifespan, old and decrepit. Please turn yourself into a forbidden zone to endure in this world!]
[Reward: One copy of the Eternal True Immortal Scripture!]

Lu Qingyun said, "If the rewards are that generous, what else is there to discuss?!"

From that day forth, the Immortal Court fell from the primordial chaos, becoming the world's ninth forbidden zone!

All living beings fell silent, overcome with despair!

[Survive within the forbidden zone for ten thousand years. Reward: One random Precious Technique of the Ten Fiends!]
[Survive within the forbidden zone for one hundred thousand years. Reward: Nine Reincarnation Seals and comprehension of the Great Dao of Reincarnation!]
[Survive within the forbidden zone for one million years. Reward: The One and Only Dao Fruit, allowing you to look down upon all heavens and myriad worlds!]

After countless ages...

When the Source of Darkness, with Immortal Kings as its soldiers and Immortal Emperors as its generals, sought to devour all heavens and myriad worlds, it suddenly discovered an eternal forbidden zone towering above them all. The dark aura it radiated was countless times denser than that of the Source of Darkness itself!

The Progenitor of Darkness said, "How about... you launch this Dark Upheaval instead, venerable one?"
