The eighty-fourth volume of the "Cloud Abode Seven Chapters" cites the "Red Book Jade Formula" saying: Ingest the breath of the five directions five times each, merging into twenty-five swallows, then stop. Practice this path for nine years diligently and sincerely, without negligence, and the true deity will manifest in form. A staff can then carry a person to travel through the air. If wishing to perform the corpse liberation, the staff can substitute form, and in an instant, transform one into a True Person. This is called 'Staff Dissolution'.
The eighty-fourth volume of the "Cloud Abode Seven Chapters" in the "Corpse Liberation Sequence and Method" discusses the 'Path of Sword Liberation for Corpse'. It describes inscribing Qu Chenfei's delicate swordsmanship on both sides of a book, first feigning illness, then lying down with the sword, which is called 'Sword Dissolution'.
