The historic rise of demons. According to the records, the power that enabled ordinary people to stand against the Ancient Cultivators was granted by the Demons.
No one knows exactly how people back then discovered the existence of Demons or how they encountered them. But as time passed, ancient ruins were uncovered, and ritual symbols began to appear, leading scholars to speculate that these rituals may have called forth an outside influence.
Yet, they couldn't rule out the possibility that these rituals weren't the actual reason Demons began influencing people. Perhaps a true Demon broke through on its own, without any ritual or intervention.
As for where these Demons came from? No one knows.
