Doster's teacher, as well as his ancestors, all specialized in refining rare treasures. He intended to research a new type of treasure, one that could evolve alongside its master's advancement, thus changing the gradual decline of such artifacts.
For this reason, he visited countless ancient Blacksmith Masters of rare treasures, and began a long journey across planes, seeking guidance from the strongest weapon craftsmen of alien races.
According to his notes, Colin even visited one of Master Bao Long's apprentices and personally received Bao Long's advice, from which he greatly benefited.
Afterward, he devoted himself to painstaking research, and finally achieved some results, preliminarily developing the so-called [Primordial Soul Treasure Refining Method].
