Show of Force... Soul Force

These two Mid-Level Emperor Grade Body Tempering Cultivation Manuals can be accessed by core disciples, deacons, elders, and other cultivators with status, but these cultivation manuals possessed more flaws.

Usually, a few or more flaws wouldn't mean anything in the long run, but if one of those flaws were fatal, it might result in a side-effect. 

The Fire-Attributed Body Tempering Cultivation Manual that Baize used made the senses numb after experiencing anger while the Earth-Attributed Body Tempering Cultivation Manual made the cultivator lose sight of oneself when experiencing extreme humiliation or similar emotions. It also has another flaw that leads to hair loss and makes one bald when they reach the Martial Sage Stage.
