In this city of bones called Akasha, memory is the currency in circulation and history is a lie.
Lin Mo, a low-level waste restorer, has a pair of ears that can hear the "echo" of all things. This talent is a tool for his survival, and it is also a curse that leads to death. When a plague called "Silent Decay" began to devour people's memories and turn patients into hollow bodies, Lin Mo's world was completely overturned.
In order to survive, he must escape from the pursuit of Ella, the temple's elite purifier. Under her holy white uniform, she hides her absolute loyalty to the order. However, when the pursuers and prey reached the darkest corners of the city's heart together, they discovered that the plague was not a natural disaster, but a shocking conspiracy aimed at cleansing minds and reshaping civilization.
When the price of truth is destruction, when the end of resistance is nothingness, how will a man who grew up in lies and a woman whose mission is to protect lies make a choice?
In this city that is about to be completely "formatted", what Lin Mo has to do is not only to retrieve the forgotten past, but also to re-weave a future for everyone.
