Qing Wo Yi Sheng Yi Shi Lian

Ah-Li is the apprentice of the Daoist Qiu Jue and they roam the country exercising demons.
It is not until they reach the capital that they hear of the suspicious ghost mansion owned by the seemingly richest man in the capital!
Just what is going on in there?
Ah-Li will not rest until she finds out (though her master really doesn't want to bother about it?!)
