"Mo Zhu Mountain Basic Sword Qi" and "Beichen Sect Ordinary True Qi to Sword Guide," these two techniques, in the aspect of inhaling and absorbing qi, are just average and aren't particularly outstanding or impressive. Refining Sword Qi and the operation of calling forth the Sword Qi also can only be said to have their own unique features. Furthermore, refining Sword Qi is rather dangerous, which could even be considered a negative point. Yet, these two techniques can absolutely achieve the transformation between different attributes of true Qi! There are no impurities in true qi!
