Huang Tao, the best editor of the magazine's supernatural stories section, suddenly resigned, leaving only a novel "The Lighthouse" that was being serialized. The novel tells a series of strange stories related to lighthouses that happened in the coastal city. The editor-in-chief gave the task of continuation to the young female editor Xiaoyu, but Xiaoyu knew nothing about the lighthouse. In desperation, she chose to go to the coastal city to find out.
