The Earth Book's defense was unmatched, but there was a reason it was called the Earth Book: it needed the land of the Primordial Wilderness to unleash its full power!
And it needed an Innate Grand Formation that could connect to that land!
Of course, with the Earth Book, setting up such a formation was simple enough.
But he had to be in the Primordial Wilderness!
This was the Extraterrestrial Chaos!
He could still use the Earth Book to set up a defensive formation, but out here, its connection to the land of the Primordial Wilderness was far too weak.
The resulting formation would naturally be far less powerful than one in the Primordial World.
So all Zhenyuanzi wanted now was to hurry back to the Primordial World, back to his own Daoist Sanctuary: Wuzhuang Temple on Longevity Mountain.
Then he could use the Earth Book to set up a defensive formation, and nothing could go wrong.
Once there, he could hole up on Longevity Mountain. With the Earth Book's unmatched defense, Zhenyuanzi would fear no number of Daluo Golden Immortals.
He might not be able to beat them, but that didn't mean he couldn't hunker down!
The Earth Book's reputation needed no explanation. As long as Zhenyuanzi did nothing foolish and stayed beneath its protection, he was confident he had nothing to fear unless a Sage came in person!
After all, no matter how many Daluo Golden Immortals there were, they were still Daluo Golden Immortals. At that level, numbers could scarcely make up for a difference in quality.
No amount of them would raise the level of their power to that of a Primordial Daluo Golden Immortal.
Thus, even if countless Daluo Golden Immortals attacked together, their power would remain at the Daluo Golden Immortal level.
