Essence Extraction Pill
The Essence Extraction Pill is a dangerous medicine used by Seven Mysteries Sect disciples to force rapid martial improvement. Li Feiyu relies on it to remain competitive, gaining immediate strength at the cost of hidden damage to his vitality and lifespan.
History
Han Li learns of the pill after noticing Li Feiyu’s abnormal condition and traces the friend’s rapid progress to repeated doses. He treats the accumulated harm as far as mortal medicine allows, but cannot erase the years already lost. Later references to the pill recall both Li Feiyu’s ambition and Han Li’s early development as a physician. (Chapters 20–24, 33–43, 662)
Properties and use
The pill extracts and burns bodily essence to accelerate martial growth. Its effect is real but fundamentally self-destructive: repeated use consumes the user’s future health and lifespan rather than building a stable cultivation foundation. Medical treatment can mitigate symptoms, not convert the borrowed strength into harmless progress. (Chapters 20–24, 33–43)
