From life to death, this is reincarnation.
From human to object, it is also reincarnation.
Through their research, the Ancient Martial Artists discovered that regardless of the method of prolonging life, it essentially changes one's form, elevating the level of life to draw closer to the Great Dao.
Therefore, based on this theory, they developed the Samsara Method. By continuously changing their form, they could transcend life and death and unite with the Dao in truth.
Practicing the Samsara Method involves transforming oneself into an object at the brink of life's end, becoming Dao Artifacts like cauldrons, bells, towers, and so on, to carry the Great Dao.
Turning from a person into Magic Treasures, that is, from a living being to a dead object, is a cycle of reincarnation.
And in this cycle, if one can understand the Great Dao they embody, they can revert to human form and smoothly break through to the Daluo Realm.
