Regular purification rituals, held every season during the Liao Yuan Festival: burn Yang Flame Grass and Golden Crow Feather, activating Fire Element Power to incinerate free-roaming Evil Qi. Soul cultivators must master the Soul Cleansing Spell: use witchcraft to resonate with the soul body's frequency, expelling accumulated gray mist (requires use with Soul Purifying Jade).
Establish the Earth Vein Compass Tower: the tower's top "Soul Observation Mirror" monitors Evil Qi concentration in real-time; the base's "Soul Suppression Stele" automatically triggers purification talisman.
Major sects jointly issued the "Jiuli Soul Scripture". Prohibited the cultivation of Devouring Techniques in the Sha Vein Area.
Train Purifying Spirit Witches: exclusively maintain purification facilities, inherit secret techniques for transforming Evil Qi (such as "Muddy Evil Refining Technique").
Si Lingle thought that the governance of Jiuli Realm was highly effective.
