Ghost Fingerprint

He remembers the touch of the keyboard, the bitter taste of coffee, and his father's words "Don't cry" before he died, but he doesn't remember who he is, what he did, or why his father's remains were sealed in a freezer at minus 60 degrees Celsius. After narrowly surviving a fire, Lin Simiao lost all memories of his identity and research. His fingerprints were found by the police next to the body of an unknown man. This man, who was marked as "suspected dead" two years ago, was once a returned IT engineer, but now he is just a blank piece of paper.
