Whenever their lifespan was about to end, some tribe leaders with great intuition would see a mysterious figure descending at night to claim their lives.
They called it: Yin Envoy.
The Witch Priest was also very clever: "No longer harvesting at a fixed age of sixty, but instead establishing a harvesting algorithm."
From then on.
The concept of lifespan began to exist between heaven and earth!
"Humans have a lifespan."
Some clever people even deduced complex formulas to calculate others' lifespans, setting up stalls to tell fortunes.
"You have thirty-six years left in your lifespan."
"You have half a month left in your lifespan."
Fortune-telling rose to prominence!
Some wise individuals began to lament:
"With the advent of gods, there came the concept of lifespan; does this mean... that humans have predetermined destinies?"
