What are the Cultivation levels in this novel?

I am in the middle of Ye family’s internal fight. I am a bit confused by the Cultivation levels. As far as know there are the cultivation levels mentioned …Qi Condensation, Division, warrior, Wu Wang(if only someone could change this into english). Not sure about the correct order.
And also there’s spirit scholar type of cultivators… I guess they should be similar to soul cultivators.
