Most of the books salvaged from the brazier had been burned incomplete, but they still yielded some information. There was also plenty of valuable knowledge within.
It was just that most of it was forbidden knowledge.
What was forbidden knowledge? Human experimentation—knowledge that violated the natural bonds of humanity.
Many passages in the books described anatomical studies of the human body, such as the forms Blood Qi took when understood through anatomy.
There were also descriptions of Rune "Extraction." Through "Extraction," the refined Blood Qi within a living creature's body could be extracted and condensed into a small Blood Qi Crystal. Such extracted Blood Qi Crystals could help Martial Artists break through bottlenecks in their Blood Qi strength.
Of course, it was forbidden knowledge because once a creature's Blood Qi was "Extracted," its life force would rapidly wither, and it would die shortly afterward.
