During the Awakened stage, only Spirit Realm natives could teach the Inner Vision Technique. Bai Xiaowen had no way to teach it.
However, after entering the Evolver stage, the Inner Vision Technique had become one of Bai Xiaowen's knowledge-based abilities and could be taught. Of course, it could only be taught to Evolvers who possessed Spirit Force.
