In fact, after spending this time researching runes with Senior Sister Lily, Kael had gained enough understanding of the Life Treasury's operational methods.
By using the Rune "thurisaz" as the core of the Rune Array, and the human circulatory system along with the transit routes of Extraordinary Power as thoroughfares, it was possible to directly extract the abnormal strength in Kael's body into the pattern formed by the Rune at the top of the head.
The name "Life Treasury" truly matched its effect.
Take the human body as a warehouse, storing many precious and cherished energies. One could say that with the existence of this skill, Kael was provided with a complete and robust "Concept Circuit".
Because the premise of extracting special powers with the "Life Treasury" was that its "tentacles" could spread to any corner of the body that might contain Transcendent Power.
