Necromancy is also known as Corpse Nourishment, and it is divided into two types: dry corpses and wet corpses.
Necromancy refers to a corpse after burial, where the hair and nails continue to grow. If the corpse was pregnant, the fetus would continue to develop as well. These are called Corpse Infants or Yin Ghost Infants.
The Corpse Nourishing Scripture mentions that in the necromancy state, the hair and nails of the corpse will continue to grow. This is due to the corpse absorbing the essence of the sun and moon or the "旺气" from its own Corpse House.
The Corpse Talk also records that if a necromancy corpse was unearthed with its mouth wide open and unwilling to close, it would actively consume humans.
Moreover, it would start by consuming its own descendants.
Xu Qing, by combining the Corpse Concealment Technique and his past experience, deepened his understanding of 'corpses.'
