Guo Huai felt dizzy.
From the moment he entered the formation, he had been in a daze.
Smack!
He slapped himself again.
He muttered softly, "It doesn't look like an illusion!"
Putting down the manual, Guo Huai sat down.
He opened his eyes a few days later.
That's right!
It was still here, and everything felt so real.
"If we are still in the illusion of the great formation, then this illusion is too real."
The things around him were real, but the key was that these secret manuals were too real.
On the third and fourth floors, all the secret manuals looked to the side.
That's right!
These manuals could indeed be cultivated, and they were very complete.
There definitely wouldn't be such things in the illusion.
Especially high-level methods.
Now that he had seen the method of immortality, Guo Huai was sure that the method recorded in these secret manuals could push people to immortality.
