In the late autumn of Yunzhou, three "Star Track" ancient jade were stolen from a jewelry exhibition, which led to the dusty old files of the Shen family's burning case thirty years ago. The clues were cut off halfway, and no one could grasp the edge of the truth.
The policewoman with long silver-grey hair chewed through the file for three days and got stuck on the most critical testimony page - that page was burned with a special potion and the writing was obliterated, making it impossible to restore it by ordinary means.
In Guan Guzhai, Laojie, there is a woman who is good at restoring ancient books. Her fingertips are stained with pine smoke ink. She can distinguish between the true and false of thousands of years of paper and ink. She is the only craftsman in the city who can restore the fragment of the page. She was always accompanied by a perfumer girl with a sharp nose. At the scene of the theft, she smelled a wisp of cold incense that had accumulated over time, which was exactly the same as the smell of dried incense shavings contained in the Shen family's old case files.
All the knotted clues ultimately point to the wooden building without a plaque in the west of the city that has been closed all year round.
The building is home to the legendary "Jade Faced Yama". He is as tall and thin as a blood-soaked bamboo, with a string of dark red rosary beads always wrapped around his wrist. He is the sharpest and coldest knife in the city - and the only one who can recognize all the patterns of Xinggui Jade.
