Samael

Lilith was taken away by Ye Ting just like that.

As a supremely gifted primordial human, still ignorant of the world, she would receive further education. Ye Ting felt that his goddesses would welcome the child.

The other primordial human created alongside her, Adam, would embark on a different path.

Adam and his "rib," Eve, would serve as the ancestors of the newborn race, striving their entire lives to spread their bloodline.

It sounded like a lofty goal, and they could live in Eden, wanting for nothing. Yet in truth, for Adam and Eve—or rather, for most primordial humans in mythology—such a life was far from wonderful.

Because as the first humans created in a myth, their lifelong duty was to breed! Breed! Breed!

The more they produced, the better. Ideally, they would create an entire people as quickly as possible.

Throughout that process, their bloodline and power would steadily weaken through endless reproduction.

Generally speaking, the stronger and longer-lived a being was, the lower its fertility.

Because the descendants of the strong were also strong, and the world would not permit so many heaven-defying beings to exist.

So if the strong wanted many children and a prosperous family, the price was either that each generation would be weaker than the last, or that they would sacrifice their own power.

As perfect primordial humans, Adam, Eve, and Lilith all possessed physiques comparable to fantasy species from birth, and lifespans similarly close to those of fantasy species.

Yet as "tools" meant to reproduce humanity, these primordial humans would basically never get to enjoy their full natural lifespans.

During their reproduction, both of the above outcomes would occur—their descendants would grow weaker with each generation, while they themselves would lose power and suffer drastic reductions in lifespan from excessive breeding.
