Shi Tiexin bought two branches of Supernatural Knowledge. Besides ocular arts, one was "Advanced Principles of Runes, Inscriptions, and Nianqi Imprints."

Because it truly was an extraordinarily exquisite secret art.
Before learning it, one unit of power produced one unit of effect. After learning it, one unit of power could produce three units of effect, with another three units of flashy maneuvering thrown in. And the flashiest maneuver was engraving inscriptions inside one's own mind.
Engraving a mental disguise of "I didn't give it my
