The Spirit Sealing Pillar was actually a huge magic tool used by ancient cultivators to seal the nearby Spiritual Qi and isolate it from the outside the world. This rarely seen magic tool was typically used in one of two ways.
One purpose was to seal extremely rare spirit medicines and spirit herbs, preventing their spiritual nature from weakening due to outside exposure. Another purpose was to suppress particularly formidable ghost spirits or devils and prevent them from escaping. Regardless of which purpose this particular Spirit Sealing Pillar served, its value would prove to be extremely significant to Han Li and company.
Spirit medicines have their obvious uses, but if the Spirit Sealing Pillar was suppressing devils, they would prove to be optimal materials for increasing the strength of one's magic treasure by subduing and containing them within their magic treasures.
