Lin Mu entered the hall where he had felt the strong immortal Qi fluctuations from.
They were strong but were still contained, thus they didn't feel oppressive.
'There are no restraints here, thus it shouldn't be an area that is not allowed for one to enter.' Lin Mu thought.
~shua~
And when he went past a certain threshold, Lin Mu could feel a presence scanning him.
'Guess they noticed me…' Lin Mu could sense someone watching him.
The first presence that scanned him belonged to an expert, but a second later Lin Mu also felt a formation checking him. He could feel the formation scan the identity token and then quickly calm down. It was evident that they were just checking who he was and whether he belonged there.
'So they added multiple levels of security despite having the illusory array outside.' Lin Mu noted as more immortal senses came over to check him.
