In this world, sound is death. A disaster called the "Great Silence" caused any sound that exceeded the limit to solidify into deadly crystal "sound skeletons." Humanity huddles in the "silent fortress" and lingers in the oppressive silence.
Lin Ji is the only "tuner" in the fortress who can resonate with sound waves. He is the hope for maintaining the survival of the fortress, and he is also a lonely person who bears the curse of the entire world.
When the last barrier of the fortress was on the verge of collapse, Lin Ji was forced to embark on an impossible journey. Together with the calm scavenger Ella, they went deep into the Weeping Wasteland occupied by Sound Skeletons and Weeping Beasts to find the forgotten source of the disaster - the "Lost Sound".
However, what awaits him is not only a deadly sonic trap, but also a dust-laden history, betrayal of humanity, and a shocking secret that can subvert the entire world's perception.
When the silent abyss stares at you, can you tune out the last overture of hope for mankind in the complete silence?
