Mansion Master had left.
He was preparing to tap into the foundation of his powers.
Chu Ning looked at his Master with a curious face and asked, "Master, how exactly will the Mansion Master establish a connection between me and the Minor World?"
He needed to understand the situation in advance to ensure no slip-ups would occur.
Other than general concerns, his primary fear was that if it were ever discovered that the Nine Realms he hailed from were actually the Guiyi Realm, it could cost him his life.
Yet he couldn't directly ask his Master what the Saint Mansion's stance on the ancient Guiyi Realm was, as asking would be tantamount to revealing his origins.
So, he could only inquire about the method of establishing a connection with the Minor World, to allow his true self to prepare in advance.
