The reason a Training Room could so drastically accelerate one's cultivation efficiency, allowing a Martial Artist to absorb Heaven and Earth Primordial Qi at a multiplied rate, was the Exotic Beast Musk Aroma burned within.
This aroma was extracted from the musk of thousand-year-old exotic beasts and refined using a Secret Technique. It could actively draw in the surrounding Heaven and Earth Primordial Qi, nourish a Martial Artist's meridians, and aid in breaking through bottlenecks. It was an exceedingly rare treasure, its value comparable to the finest Heavenly Materials and Earthly Treasures.
Even among the five great sects with their profound resources, the Exotic Beast Musk Aroma was considered a strategic-level reserve, rarely used in large quantities on a day-to-day basis.
Even the well-established Xuanzhen Sect didn't have a large stockpile of the Exotic Beast Musk Aroma.
Every single portion had to be carefully rationed and used only where it mattered most.
