On the roof was the condemned soul, staring right at her while clinging to the roof upside down. Its void eyes were staring at her unblinkingly and Song Yan rubbed her ring, prepared to deal with that thing if it made a move but surprisingly it didn't, instead it stayed where it was, with its gaze flickering between her and Fang Yanli. 

" It can sense my cultivation level," said Fang Yanli as she finally realised why the condemned soul wasn't attacking them. " Maybe these things can't sense the cultivation level of a human but it can definitely sense mine. It knows that at the moment it's a lot weaker when compared to me, that's why it hasn't moved an inch from the roof." 

The fact that the condemned soul was able to think so much and have such an understanding struck ominous to Song Yan as she looked at Au Lisha and said, " Please take me there quickly."
