As an ancient book restorer, I received a criminal investigation file from the Republic of China that could modify the text on its own. The first case points to the "Blind Corpse Mystery Case" that caused a sensation in Shanghai: all seven victims had their eyes gouged out, and before they died, they all wrote "I do" with a smile. When I repaired to the last page, I found that my name appeared on the victim list. The new annotation, which was still wet with ink, read: "This time, you choose to gouge out the left eye or the right eye." At three o'clock in the morning, the studio phone rang, and the other party's voice sounded exactly like mine: "What you are repairing is not a file, but a contract." "We all signed our names."
