I was lying on the hospital bed, my eyes were dull. I didn't know who I was now. I had no identity, no name, or even a past. The days passed by like this. Until that day came when I received a gift that would change my life. It is a leather notebook. The moment I opened the notebook, countless thoughts flowed into my mind. The owner of the diary is named Zhao Yu. He came to Linchuan County in the 25th year of the Republic of China and became a Linchuan County police officer. Later, he repeatedly solved mysterious cases with his keen observation skills and super logical thinking, and became famous, but then he mysteriously disappeared. I would like to share the content of this diary with everyone. I hope you will stay, listen to me and help me analyze the origin of this diary and the reason why it appears here.
