At midnight, the clock did not ring. The last time Zi Shu died in the bell tower, there was a black bone in his chest that did not belong to the twelve earthly branches. Li Zhao, an apprentice clock repairman, was forced to inherit the throne, and from then on he could read the memories left by the dead and old objects - at the cost of forgetting a part of himself every time he saw a piece of the truth.
Yinhu disappeared, Xugou lied, and the eleven timekeepers were all trying to find out what he had seen. Li Zhao pursued all the way, only to find that underneath the twelve locations that kept the world running, there were also a group of people who had been deleted from the map and memory.
When the truth is enough to collapse time, he must decide: keep the secret and become the next accomplice; or let everyone see the name of the victim.
