In Liuguang City, where steam and spiritual dust intertwine, memory is both wealth and curse.
Lu Yan is a top "memory weaver". His job is to sneak into the remnants of the deceased's memories and pursue the buried truth. He is used to seeing the ugliness of human nature, and his heart has long been like a frozen lake. Until a bizarre "blank" death case occurs - the victim's memory was not tampered with, but was completely swallowed up by an unprecedented "nihilation".
In order to pursue this piece of nothingness, he stepped into the darkest downtown area of the city, and unexpectedly met a girl Evelin who burned like a flame. In order to find her missing sister, she did not hesitate to make enemies of the whole world.
The two threads of fate are entangled. From the dirty alleyways filled with steam to the sky corridors with gears biting, they discovered that behind the nothingness that devoured memories was a terrifying conspiracy - the "Silent Agreement" - aimed at erasing the emotions and personality of the entire city.
When the memories of loved ones and the soul of the city are about to be formatted into absolute order, Lu Yan must make a choice: continue to be a numb bystander, or rekindle the embers in his heart and embrace the pain, joy, and love that define what makes a "human" human.
However, none of them knew that in this war between memory and nothingness, what they were fighting might just be the prelude to a larger existence...
