The world was dragged into eternal night by a disaster called "Silence Comes". Monsters called "Whisperers" were born from the shadows, preying on the remaining humans. In an era of despair, some humans awakened the reverberant power called "Echo" and became "Echoers". Lin Yebai, a young man struggling to survive, awakened to a unique but considered most useless echo - observing and interfering with the "data flow" that constitutes reality. Initially regarded as a useless liability, he soon discovered that this power allowed him to rewrite the laws of reality, optimize the abilities of other echoers, and even "debug" monsters that dominated the world. He must struggle to survive in the treacherous storms of the Survivor Citadel City, uncover the truth behind "The Fall of Silence", and face the cosmic malice that caused it all.
