The difficulty of brewing True Sword Liquid was considerably higher than that of Jade Wash Spirit Dew and similar.
The main materials were from the sword grass category of spirit plants, and due to the differing attributes of sword grass, the final product of True Sword Liquid might have subtle variations in taste and effects.
Since the texture of sword grass was tough and it contained countless fine Sword Qi, the processing difficulty was many times more complex than ordinary spirit plants. A slight mishap could lead to total failure, resulting in waste.
Furthermore, the requirements for the brewer were exceptionally high, needing expertise in subtle Sword Dao techniques with the division of Sword Qi being particularly crucial.
Fortunately, Lu Xuan had previously realized and practiced "Spectrum Sword Sutra" while cultivating Spectral Splitting Shadow Sword Grass, which laid the foundation for brewing True Sword Liquid.
