Since the emergence of the Anomalous Guests, the world has been graced with numerous wondrous and peculiar phenomena. As a physician, despite my limited knowledge, I presumptuously, with the shallow understanding of a frog in a well, endeavor to discover the wondrous applications of such strange objects.
There is a stone named ‘Runwu’. Its surface is moist and viscous, unlike solid rock, differing greatly from ordinary stones; it resembles hardened mud and is tasteless. When crushed into a powder and dissolved in water for consumption, it possesses the efficacy of soothing the stomach and intestines.
There is a herb named ‘Shiwei’. Its leaves are slender with finely serrated edges, and it tastes dry and astringent. When ground into a powder and added to dishes, it can enhance their flavor and color. While it causes a slight itch upon touch, it is harmless.
There is a tree named ‘Qixianghui’. The tree itself is thick and straight, bearing unusual flowers. These small flowers possess a subtle fragrance and are indeed medicinal. Peeling its bark reveals a peculiar aroma, which has the effect of calming the mind and settling the spirit.
Individually, all three of these items are non-toxic. However, when encountered together, they coalesce into a potent poison. Should Runwu be consumed dissolved in water, the skin touch the powder of Shiwei herb, and the unique fragrance of the Qixianghui tree be inhaled through the nose and mouth, this combination, once entangled within the five viscera and six bowels, immediately becomes a deadly toxin. Even the most formidable protective martial arts techniques offer no possibility of resistance. This potent poison circulates throughout the entire body in mere breaths. Upon attempting to activate one’s cultivation, it causes one’s internal energy to completely dissipate. While this poison is not fatal, and one can recover to normal in just a few days, the lost internal energy cannot be regenerated. Should one be afflicted by this poison during combat, the complete loss of internal energy poses an even greater threat to life.
Because this potent poison is virtually impossible to guard against and requires no specific antidote, its preparation formula has been appended to the ‘Strange Poisons’ volume of the *Thousand Formulas Classic*. Those curious may consult the ‘Strange Poisons’ volume of the *Thousand Formulas Classic* for a detailed look.
The strange occurrences in this world are truly beyond imagination. The three aforementioned items are all medicinal and not rare; though inherently non-toxic, their combination yields a potent poison. This amply demonstrates that the wondrous transformations of all things in the world far exceed what we ordinary mortals can predict, further highlighting the critical importance of inquiry and exploration.
