At the end of the world, ink rain pours down, and the physical three-dimensional world collapses into a two-dimensional black and white painting. The lighting engineer Su Li awakens the "collection system" to condense the painting record, using a solitary pen as a blade to collect the remaining colors of the world, splashing ink on the flat wasteland to create gods and reconstruct dimensions!
The urban wasteland eroded by "Ink Rain". The "thickness" and "color" of the world are being lost, and the three-dimensional space is being flattened into a two-dimensional ink painting. If human beings lose color and thickness, they will become the irrational two-dimensional paper monster "Ink Soul". A very small number of awakened people rely on the strong obsession in their hearts to cling to the final three-dimensional physical form.
