Su Miaoqing is the daughter of Su Qianyi, the master of Boundless Hall. Like Su Qianyi, she possesses a fire spirit root and practices the most orthodox cultivation method, the Nine Volumes of Heaven-Inquiry, which is unmistakably the technique of Boundless Hall.

What does this imply? It suggests that Master Qingxu is now on the verge of soul collapse.
