The Black Poison Faction would often use certain aged dark mist monsters as samples, demonstrating the life extension effects they were researching.
Their most common dog and pony show:
First, they'd inject the potion, and the aged dark mist monster would return to youth.
Then they'd paint a rosy picture of applying this experiment to humans.
This performance greatly attracted investment from various organizations, including secret contact from human organizations.
In reality, the dark mist monster's return to youth performance was a kind of mature flesh mimicry that the Black Poison Faction had developed, completely unrelated to life extension.
"Moreover, later generations discovered that the news of the Golden Sand Society conspiring with traitors was actually reported by the Black Poison Faction themselves."
It had to be said that this faction's extremely brief period of prosperity before getting wiped out in later generations had its reasons.
