The Nine-turning Flowing Pearl Immortal Nine Pills Sutra. The original title was written by a real person from the Taiqing Dynasty, and it must have been attributed to Taoist priests from the Southern and Northern Dynasties or the Sui and Tang Dynasties. This book has been quoted in Volume 4 of "Daodian Lun" in the early Tang Dynasty. Its content is also similar to the Nine Turns Pill Jue contained in Volume 1 of "The Yellow Emperor's Jiuding Shendan Sutra Jue". "Tongzhi·Yiwenlue" contains three volumes of this book, and two volumes remain. Original source: "Orthodox Taoist Canon", Dongshen Department's Various Techniques Category.
