A stone table was prepared for every Desolate Heaven Master apprentice in the Desolate Heaven technique classroom. On each stone table there was a disk array used for refining desolate bone relics. There were runes inscribed on the three foot long square disk array.
Beside the disk array, there was also a meter tall cabinet. The cabinet was a storage device, similar to an interspatial ring. They all contained large amounts of desolate bone materials.
Desolate bones were usually extremely large. Some primordial desolate beasts could even be as long as a 50 kilometers, or even 500 kilometers. The desolate bones of such a large desolate beast would look like a winding mountain ridge when laid out on the ground. Even a sage-grade Desolate Heaven Master would find it difficult to refine such enormous desolate bones into desolate bone relics.
