577 Demonic Alchemy

Looking at the recipe, Xuan Hao could not help frowning to himself after reading halfway through it.

The spiritual herbs required for the medicine was nothing abnormal at first and just consisted of normal spiritual herbs that were not too hard to find inside the Flying Sword Sect. However, the last few things on the recipe were what truly allowed the potion Elder Song was refining to be considered a demonic medicine that belonged among something made by a demonic alchemist!

Not only did the recipe call for a sacrifice, but it also called for a lot of different things Xuan Hao had never heard about being used in alchemy before like the blood directly extracted from the heart of a pure maiden and other vile materials!

Feeling a bit doubtful when he saw so many disgusting things needed for the recipe, Xuan Hao could not help glancing curiously towards Elder Song. Wondering how he had used as a substitute for those things.
