The difficulty of brewing True Sword Liquid was significantly higher than that of Jade Wash Spirit Dew and similar concoctions.
The primary materials were Sword Grass-type Spirit Plants, and the different attributes of Sword Grass could lead to subtle differences in the taste and effect of the final True Sword Liquid.
Among them, the hard texture of Sword Grass, containing countless subtle strands of Sword Qi, made its processing many times more complex than that of Ordinary Spirit Plants. A slight mistake could render all efforts void, turning it into waste.
Additionally, the requirements for the brewer were very high, needing to master exquisite swordsmanship, with the division of Sword Qi being particularly crucial.
Fortunately, Lu Xuan had previously practiced the "Spectrum Sword Sutra" while cultivating Spectral Splitting Shadow Sword Grass, which provided a foundation for brewing True Sword Liquid.
