Gu An stabilized his Qi and then looked towards the door.
He did not know who was approaching.
However, the fact that he could perceive it so clearly meant it probably wasn't a very powerful person.
The stars had completely disappeared, and others in the Sealed Land were also unable to detect it.
He observed the surroundings again, and once sure that everything was fine, Gu An took a deep breath and asked, "Who is it?"
It was too obvious, and pretending not to notice would be far too fake.
"Senior Brother, it's me." A voice of an unfamiliar Immortal came from outside.
Gu An opened the door and saw an Immortal who looked about twenty-five or twenty-six, standing there somewhat nervously.
Perfect Foundation Establishment cultivation.
Gu An did not recognize her.
The Immortal looked at Gu An and respectfully asked, "Are you Senior Brother Gu An?"
Gu An looked carefully; indeed, the person was at Perfect Foundation Establishment.
This was somewhat unexpected.
Not a spy.
