"Preserving a thread of vitality, the Corpse Scattering Person resurrected in an unusual form..." Qingyu glanced at the records about Fatty Lan, "Hmm, when I have time, I should capture a Corpse Scattering Person to study, to see if I can uncover some mysteries about life and death."
The Corpse Scattering People of the Heavenly Demon Palace are said to be made through methods of Corpse Refinement. In reality, they still retain a trace of vitality. It should be said, without that trace of vitality, they wouldn't qualify as Corpse Scattering People and would simply be refined into zombies.
After all, once a person is killed, they die; if one were truly dead through and through, resurrection would not be so easy.
