Outer Celestial Demon.
It was regarded as a formidable enemy by the ancestors.
Yet Lu Yuan had never encountered it from beginning to end.
But that did not stop him from preparing in advance.
Take the Black Blood before him, for example.
Through it, Lu Yuan had already begun to understand some of the powers of the Outer Celestial Demon.
It completely restrains this world, but having cultivated to his current realm.
He understood the concept of mutual generation and restriction of all things.
Even if it's the Outer World.
Although entirely different from this universe, this principle would never change.
Therefore, when he saw that more power was needed to suppress the Black Blood, Lu Yuan knew it wouldn't work.
In such a case, what if all the Outer Celestial Demons descended on this world?
By then, only those with strong power would likely survive.
But more would be in grave danger.
As previously mentioned.
This time.
