Impermanence in Prison: Strange Cases of the Five Dynasties

This story is purely fictitious and any similarity is purely coincidental and has nothing to do with history. When Gu Bei, a modern detective, was chasing a murderer, he was sucked into the wordless ancient slips of the "Yin Yang Library" and became a wanderer in Dali Temple numbered "Impermanence". He was forced to travel through the five dynasties of Qin, Tang, Song, Ming and Qing to solve strange cases that "history books dare not record". Every time a case is solved, a line of blood is added to the ancient slip. After the book is full of blood, there is a chance for the soul to return, but in the end, it faces the ultimate proposition of "killing oneself".
