If their spirit fire wasn’t completely extinguished, these spectral creatures wouldn’t truly die. They could re-absorb power from the spectral demiplane and re-form their bodies.

However, a lot of energy had to be expended to reconstruct undead from spirit fire. The source of this energy was the spectral demiplane.

It wasn’t as stable as a main dimensional plane like the Douluo Continent. More simply put, the spectral demiplane was like a dimensional plane that was formed using pure energy. Everything inside it was made using energy.

During the process of creation, Electrolux must have used some kind of unknown method to pour in extremely stable energy. This stable power was enough to ensure self-sufficiency. Once the spectral...
