Even though he had already become a living Yin messenger and had captured a few Yin criminals, Li Yan was still confused about the Yin Bureau.
Under the candlelight, he carefully flipped through the pages, his brow furrowed.
This recorded experience of being a living Yin messenger not only contained records by Liu Gang but also narrations by a "guest from Taishan" whom he met.
The format of these records was somewhat like medical case studies.
Each case described where the task was picked up, the visions seen while accepting the task, the story of the Yin criminal, and even the process, all meticulously documented.
This method had numerous benefits.
First, it allowed for the passing down of experience; second, it facilitated summation and generalization.
Li Yan could be regarded as a halfway joiner. He had obtained the Hook Paper and, with great difficulty, found a legacy that was about to vanish.
The only thing left was a "Yin Law."
