Chapter 729

But the Nine Heavens and Ten Earths have no Immortals, and I am afraid they are not the opponent of the other side.

However, an old man revealed a secret.

He said that the world of the Nine Heavens and Ten Earths is also very mysterious, with many unsolved mysteries,

such as several forbidden areas, existing since ancient times, which existed as early as the beginning of the Immortal Ancient Era or even earlier,

and now they still stand, almost no one can set foot in them.

Perhaps there are experts who can block the foreign realm.

Also,

above the Imperial City, there is an old city, existing for long years, difficult to trace,

it is outside the giant city of the border wasteland, floating and sinking with the world, letting time flow, always suppressing there.

It suppresses everything, blocking the foreign realm's iron hooves from stepping into this world!

This city is boundlessly mysterious; some say it is ominous, an ancient city cursed,

with long years, impossible to examine, representing suffering, often accompanied by blood light.

Others say it is the greatest city, guarding the border wasteland and protecting this world.
