"This... when I first consigned it to Treasure Pavilion, the staff there had mentioned that this 'Purple Sky Meditation Skill' might very likely be a secret technique from some sect that had fallen into the outside world."
"As it happens, I obtained it by a stroke of luck, and now, besides myself, there is no one else who has learned it."
"This jade slip is the original, so after my fellow Daoist purchases it, it can be freely passed on to your future generations, without any worry."
"Thus, it is quite accurate to call it a secret technique, because the only people who will know this technique are myself and the one who ends up buying it."
"Rest assured, fellow Daoist, I have a contract with Treasure Pavilion. Once the transaction is completed, I will no longer be able to pass on this secret technique to anyone."
