Cleansing Water Gu

It resembles a leech, though much cuter than one, and its whole body has a light-blue luster like glimmering water. ^{ch. 111}

On the caravan treehouse counter it resembles a leech, with a whole body of light-blue luster like glimmering water. ^{ch. 111} No cited chapter states its Rank in plain words.

It removes mixed aura in the aperture. ^{ch. 111} That effect cleanses aperture walls and flushes external energies so the sequela of foreign essence can be cleared. ^{ch. 50} It completely washes away impurities in the aperture, and it is the most common method for clearing the black-red residue left by Man-beast Life Burial Gu. ^{ch. 152} Tie Ruo Nan later states that it has only one use: cleansing foreign primeval essence auras from the aperture. ^{ch. 179}

It is again the cure for mixed aura after an elder imparts primeval essence, and it is a rare Gu that ordinary Gu Masters struggle to obtain. Even elders must rely on luck or pay a tremendous price. ^{ch. 226}

After the Liquor worm leaves the central counter of Jia Fu’s caravan treehouse, a Cleansing Water Gu takes that place. Fang Yuan judges that Chi Lian will buy it for Chi Cheng, estimates Chi Lian’s quote at about six hundred thirty to six hundred forty primeval stones, and judges that six hundred fifty would win it. He does not bid. ^{ch. 111}

The treehouse specimen is later bought by the Chi faction. ^{ch. 152} Chi Lian did buy that Gu and held it for Chi Cheng. ^{ch. 155} Jia Fu’s intel to the Tie investigators also records when and at what price Chi Lian bought it, though that chapter does not quote the number in the narration. ^{ch. 179}

During the wolf-tide stretch Fang Yuan forces Chi Lian to hand the Gu over, framing the transfer as a loan with a signed receipt, and leaves the Chi manor with the Gu plus three thousand primeval stones. ^{ch. 155} By chapter 159 that Gu has already been used. The black-red Man-beast Life Burial Gu residue in his aperture is gone, and he notes that without the cleansing his aptitude would have fallen further than the drop he already took. ^{ch. 159}
