Elixirs were divided into the Qi Sea Level and the Spirit Level.
The Qi Sea Level was further divided into six grades: Low, Mid, High, Peerless, Perfect, and Supreme.
Spirit Level Elixirs were divided into eight grades: Low, Mid, High, Peerless, Holy, Emperor, Celestial, and Dao.
All the elixirs Nie Yun had encountered before were of the Qi Sea Level. Even the strongest among them were only Supreme-grade—he had never come across a Spirit Level Elixir.
Spirit Level Elixirs had already developed their own Spiritual Wisdom. The most powerful ones could even take human form and cleanse themselves of their Pill Qi, becoming completely indistinguishable from humans!
Although these elixirs hadn't reached the stage of taking human form, they were still Low-grade Spirit Level Elixirs. Their medicinal fragrance alone could greatly invigorate a person, allowing them to fight for three days and three nights without their True Qi running dry.
