"Third-grade pill, Dust-Removing Pill, can remove impurities from a cultivator's body and reduce the risk of mutation. Pills with such effects are quite rare."
Lu Xuan examined the fragrant round pill in his palm and murmured to himself.
During cultivation, if a cultivator absorbs and refines spiritual energy in a low-level spiritual vein environment, some tiny impurities might remain in their body. Over time, this accumulation can affect their ability to break through to higher realms.
Additionally, staying out in the wild for long periods and coming into contact with murky spiritual energy can speed up this accumulation of impurities. In such cases, if they encounter malevolent spirits, it becomes easier for them to mutate into strange creatures.
Lu Xuan had once seen a Qi Refining cultivator mutate in Linyang Market Town, suddenly attacking other cultivators indiscriminately.
