The Silent Harbor

Restorer of ancient texts Shen Yan discovers an ownerless diary in tide-damaged archives, following the ninth person, Lu Jingzhi, who vanished on the night the 'Zhaoming' returned to port seven years ago, and is dragged into a live memory experiment and serial silencing covered by a 'Silence Agreement'; the silver chain on his wrist hides Lu Jingzhi's evidence, and the bell tower rings by itself when no one is there, a device Lu set up before his death to overturn the case. On the night of the sinking bell sacrifice, Shen Yan sneaks into the bell tower cellar to find his father's body and complete archives, and the harbor bell finally rings for the people. — Description from novelcodex.org
