Legend has it that Wudang Mountain once possessed a miraculous remedy, capable of curing all ailments instantly. Those who were healthy and took this medicine could extend their lifespan. The Daoists of Wudang called it the "Eight Treasures Purple Gold Pill." Regrettably, this precious remedy has long been lost to Wudang. Now, Wudang’s Taoist physician, Wang, seeks to recreate the legendary Eight Treasures Purple Gold Pill. This is a daunting endeavor from the outset, where even the slightest mistake could greatly diminish the medicine’s efficacy.
