Calling it Mind Cleansing was a bit much. These methods and the rule of recruiting only monsters were, at their root, meant to compensate for poor cultivation conditions and scarce resources.
If an academy like Shrek recruited ordinary students while demanding they graduate at level forty, it would have shut down long ago.
Soul Elder was a dividing line for most spirit masters. After reaching Soul Elder, without a Mimic Cultivation Environment, their cultivation speed would drop sharply.
True geniuses, however, were far less affected by Mimic Cultivation Environments than ordinary spirit masters.
Quite a few academies on the continent had Mimic Cultivation Grounds, but only three possessed a relatively comprehensive range of attributes—
Heaven Dou Royal Academy, Star Luo Royal Academy, and Spirit Hall Academy.
Did academies like Five Elements Academy and Plant Academy really not understand the flaws of the Extreme Flow?
Plant Academy in particular was completely countered by lightning and fire attributes. Where could they find so many plant spirit souls resistant to lightning and fire?
Most likely, they had lacked the funds to build multi-attribute Mimic Cultivation Grounds when they were founded, so they had settled for the next best option.
Blazing Academy only needed to build beside a volcano, Godwind Academy only needed to find a wind valley, and Plant Academy only needed to locate a dense forest... How economical!
The usual graduation standard for advanced Soul Master Academies was level thirty, but that applied only to ordinary students.
Almost no students competing in the Spirit Master Competition chose to graduate at level thirty.
Achieving results in the competition made recruitment easier for the academy and also served as part of the students' credentials.
Over time, these Extreme Flow academies built up their reputations, developed their own characteristics, and continued on.
