He thought death was the end. He was wrong. His death was the beginning of a path with the potential for infinite power.
One moment William was at work, and the next, he was surrounded by lunatics wanting to sacrifice his soul.
He had never been a man who believed in the fantastical, but he had no choice after he found himself in a much younger body in another world. A world that had things like soul extraction and demonic cultivators, and if nothing was done, his soul was next in line to be reaped.
Thankfully, a man with a special hatred for demonic cultivators saved William at the last second.
The man also left him a tool. A system that would guide William to the heights of cultivation.
