At 0:13 in the morning, the last subway train in Linzhou City disappeared out of thin air. Seven minutes later, the train entered the station again, but there was an extra body covered with green feathers in the carriage, and a child who had been forgotten by everyone was missing.
Zhou Jiming, an investigator from the Shanhaisi Division, can hear the "true names" of all things, seal strange beasts with their names, and rewrite the rules, but at the cost of losing his own memory. Until he met Xie Wuwang, an ancient book shopkeeper with no past, no heartbeat, and no real name.
As the Nine Tails fell into a dream, Kunlun fell into the city, and the tide of return to ruins emerged, Zhou Jiming discovered that the "Book of Mountains and Seas" was not an ancient mythical book, but a sealed list that bound the fate of all living beings; Xie Wuwu was the only one not in the book.
When the gods return and the world is about to be renamed, he must choose between saving the world and preserving Xie Wuwang.
One knows the names of all things, but gradually forgets himself; the other has no name, but tries his best to become a real person.
"What if one day you forget even me?"
"Then let's get acquainted again."
