Every human has their Personal Jewel of power, when awakened it can either be an Elemental Jewel or Physical Jewel. They circle the right and left wrists like bracelets of power. Heavenly Jewels are like the twins born, meaning when both Elemental and Physical Jewels are Awakened for the same person, the pair is recognized as Heavenly Jewels. Those people who have the Physical Jewels are known as Physical Jewel Masters, people that have Elemental Jewels are Elemental Jewel Masters, and the ones who train with Heavenly Jewels are naturally called Heavenly Jewel Masters. Heavenly Jewel Masters have a highest degree of 12 pairs of jewels, therefore their training progress is recognized as Heavenly Jewels 12 Changes. Our MC here's an archer that has such a set of Heavenly Jewels.
