Deep in the brightly lit modern city, ancient secrets and extraordinary powers are quietly awakening. Ling Xiao, a young man who works in the municipal library and has the "glazed eye" power but doesn't know it, his peaceful life is broken by a series of strange and bizarre disappearances. The victims in these cases all came into contact with a sealed ancient book in the library before disappearing.
Interpol Gu Qinglin was ordered to investigate these seemingly unrelated disappearances. His rational logic gradually wavered when faced with unexplained supernatural phenomena. When Ling Xiao was involved, his "glazed eyes" began to show the power of prediction and insight, guiding him to discover the rune barriers hidden in the shadow of the city and the signs of the resurrection of the ancient evil gods.
As the investigation deepens, Ling Xiao and Gu Qinglin gradually build trust from their initial suspicion and conflict. They must join forces to uncover the forgotten truth behind the ancient books and prevent a catastrophe that could subvert the urban order. However, the power hidden behind the scenes is far more powerful and cunning than they imagined, and an urban legend about memory, destiny and sacrifice begins.
Tonight, however, the library seemed a little different.
