Why can Immortals achieve the level of rebirth from a single drop of blood?
It is because the body of an Immortal, every drop of blood, even each cell, can automatically absorb external energy, recording complete genetic information.
The physique of an Immortal is already akin to memory metal.
Unless completely destroyed, they can absorb external energy and continuously regenerate.
It is due to this that even if an Immortal dies, their corpses remain immortal through millions of years, never fading with time and still possessing strong vitality.
Of course, the soul of an Immortal is the most crucial.
Because the soul is the carrier of memories.
If one loses memories and self-will, they become nothing but a walking corpse.
Leaving only a shell has little practical purpose.
