This is a world torn apart by words and spirit bones: if one word of the reed leaf song in Linhe Town is missed, it will fall into the eternal night; the foggy shadows in Wuyong Mountain come to life after being named and walk in the world in place of living people; the word keepers in Anyi County use bones as shackles to build the entire city into a dictionary that can eat people. And the end of all the rules points to the annihilation fire of the Eldar tribe a thousand years ago - they once carved the laws of heaven and earth on their bones with the blood of their tongues, but they were backlashed by the rules they created, and the remaining bones turned into a silent barrier, trapping mortals on the gallows of "speech follows the law" and "loss of speech means death".
