Spirit monsters like these Demon Beasts are very rare and uncommon in the Cultivation World.
For Human Clan Cultivators, if such creatures are taken as Spirit Pets, they can greatly profit in certain aspects.
For example, a Wood Charm possesses the innate ability to find Spiritual Medicine and hasten plant maturation.
The fact that a Snow Charm can refine Dharma Treasures with the Myriad Year Mysterious Jade and locate the Mystical Nether Dark Water Eye suggests it has a special talent for finding ice-attributed ores and Spiritual Objects.
Back when Zhou Chun was searching for those Snow Crystal Worms in the Yang Kingdom, if he had let the Snow Charm look for them, it would probably have found them easily.
Yet, this is only how Cultivators below the Nascent Soul Stage can utilize such spirit monsters.
For Nascent Soul Stage Cultivators, another more beneficial way to use spirit monsters is to refine them into their own Incarnation.
