Capítulo 245: Chapter 242 How Numerous Are the Demonic Paths

The Pill Seal technique, much like the Four Symbols Elixir Seal used by the junior disciples, was originally passed down to them by Song Yin himself.

Refining elixirs, refining elixirs, herbs and plants can be refined; so can metals and stones. Different materials yield different results when refined.

Why must your next alchemy attempt be with herbal elixirs?
