Using both his magical power and spiritual sense, Lin Changheng obtained a clear picture.
Tantai Feiyue had a solid foundation of magical power. It was quite substantial and filled her dantian; she clearly had not lacked resources.
The problem, however, was that her magical power was far too impure, plainly a result of consuming large quantities of assorted pills.
Liquefying her magical power would be incredibly difficult when the time came.
It would obstruct her passage through the [Mountain of Qi].
The pill toxins left behind would also weaken her body and drain her vital essence. She would be unable to contain the influx of spiritual energy from heaven and earth without it leaking away, making the [Mountain of Essence] difficult to overcome as well.

Second, she had progressed rapidly in the Talisman Dao. Drawing talismans frequently exhausted her mind, which then recovered. Repeating this cycle had tempered her soul to some extent.

Even if he gave her the [Foundation Establishment Spirit Treasure] as well, the combined increase would be only twenty-five percentage points.
That was the
