Psychiatrist Wen Renfei's clinic specializes in treating patients with various "hypotheses". But he has a secret: inside his ears, there lives an indescribable ancient god. It whispers from time to time, revealing crazy secrets and terrifying knowledge from the deepest reaches of the universe.
In order not to go completely crazy in endless babble, Wen Renfei was forced to become a "babble decoder." He used these leaked words to solve a series of strange cases that ordinary people cannot understand: the "living" paintings left by the missing painter can drag people into an alternate dimension; the ancient villages on the sea cliffs used human beings as sacrifices to the ancient rulers sleeping on the seabed; deep in the city sewers, invisible monsters formed by the collective nightmares of mankind breed...
He was curing others of their madness, but his own sanity was being eaten away at a rapid rate. He got acquainted with a mysterious organization responsible for dealing with abnormal events, and also encountered cultists who worshiped madness. While dealing with these people and monsters, he is also tracing the secrets of his family - why does this raving only ring to him?
He maintains his identity as a "human" while walking on thin ice, because he knows that when he can fully understand the language from beyond the stars, it will be the moment when he bids farewell to humanity completely. And that day is approaching.
