Only a hundred thousand years had passed.
The plane before Li Yun's eyes was utterly different from when he had first arrived.
A hundred thousand years ago, the plane had shown signs of decline, and Ominous Miasma had begun to seep in, but its order had remained relatively stable.
Yet a mere hundred thousand years later...
Ominous Miasma permeated the entire plane. Countless worlds had been tainted by it, and all manner of problems had begun to emerge, starting with the Three Thousand Great Daos themselves.
Every world infected by Ominous Miasma had, without exception, been sealed by an invisible force. Its living beings could not leave. They gradually developed all kinds of ailments and died wailing.
The entire plane suffered the same fate.
Order collapsed.
Even the Great Dao Divine Lords who realized what was happening could not cross the plane's barrier to escape.
Not even the wielder of a Third-Rank Divine Image, who held a Shallow-Layer Plane Authority, could protect himself with it. His attempt to ward off the corrosion of Ominous Miasma had no effect whatsoever.
Plane Authority gave him a protective barrier, but Ominous Miasma still followed an invisible Karma Thread through it and corroded his body...
In short...
As time passed, the plane's decline deepened and the ominous aura seeped in faster. Apart from Li Yun, an Undying Ancient God who had developed immunity to it, everyone in the plane was gradually being corroded by the ominous aura.
