Golden Core Outer Pills were universally accepted as a type of Immortal Pill.
It was a creation of Immortal Scenic Yang, an illustrious figure in history! Back then, Immortal Scenic Yang had gone to great effort to invite experts from various disciplines to eventually refine the transcendent-grade Dharma treasure, Golden Core Cauldron. With the cauldron, he refined many potent pills. One of the most famous and most impressive pills was the Golden Core Outer Pill. This was also why the cauldron was eventually given its name. And after Immortal Scenic Yang's death, no one else could refine Golden Core Outer Pills. As such, these pills became a legend.
Although there were some Golden Core Outer Pills that circulated through the world, they were long consumed over the span of three thousand years, becoming a legend as well.
The Golden Core Outer Pill would enter the dantian on consumption! It was as though one had cultivated to form a Golden Core.
