This is actually his other spare body.
——"Cloning Technique (8th ring spell) (Necromancy School): This spell creates a lifeless clone of a creature. If the original creature is killed, its soul will immediately transfer to its clone and resume activity. The original remains will still exist but will lose vitality and cannot be used to receive souls again. If the original body died at the end of life (that is, natural death), the clone will not function.
When creating the clone, you must take a part of flesh from its living body (hair, nails, scales, etc., are not acceptable). After casting, the clone must be stored in a laboratory for cultivation for a period of 2-8 months.
Once the clone is complete, if the original body has already died, the soul will immediately enter the clone.
When the original body is still alive, or the soul cannot return, the clone will also grow, but this body will merely become a soulless flesh, and without proper preservation it will decay."
