According to legend, when a saint ascends to heaven, he will leave a stone behind, which is called the "Song of Saints". Because the canonization stone is the crystallization of the saint's source of power, it is a treasure that will never come out, and is fought for by powerful people from all walks of life. However, the Holy Stone is so intelligent that it knows how to disguise itself and cover its brilliance with the mortal world, so it is difficult for the world to find its traces... Only those who are truly destined can discern the pearl with a keen eye. Boundary divisions: Source of Origin, Source of Dou, Different Source, Treasure of Source, Blue Source, Spiritual Source, Return to Source, Tianyuan, and Holy Source realms
