Those who practice cultivation attach great importance to their post-death arrangements. This is because once they embark on the path of cultivation, they develop certain extraordinary qualities to varying degrees. The more powerful the cultivator, the truer this becomes!
For low-class cultivators below the Spirit Sea Realm, including those in the Body Tempering and Qi Gathering Realms, it doesn't matter much if they are indiscriminately buried in any hole after they have fallen. At most, they might be buried in a Yin-Nourishing Land, where their corpses are preserved from decay. Then, their bodies could be exhumed by disciples from immortal sects like the Ghost Corpse School, who refine corpses into Ghouls.
If one finds it too ominous for their corpse to be refined into a Ghoul after death, they can make arrangements in advance, or instruct relatives and friends to cremate their body and bury the ashes!
