Qingmu City, located several dozen miles southwest of Medicine King Valley.
As the city nearest to Medicine King Valley, it used to be bustling with heavy traffic and unparalleled prosperity, boasting a population exceeding five million.
After all, before the advent of the Heavenly Extreme Holy Sect, Medicine King Valley had been the only dominating power within the territory of West Barbarian Mountain.
The pills produced in the valley were the sole ones available within the territory of West Barbarian Mountain.
From the formulas to the sources, everything related to pills was essentially controlled by Medicine King Valley.
And pills were something every cultivator essentially needed.
Other medium and small-sect cultivators who wanted to use the power of pills to aid in their cultivation had no choice but to purchase from Medicine King Valley.
The sect entrance of Medicine King Valley was an important place, heavily fortified, not something any random person could enter.
