Lu Chuan transmigrates.
His soul enters a parallel world known as the Abyssal Realm.
He becomes a monster, the weakest kind of all: a Blackscale Beast.
His own kind want to eat him, and humans want to kill him.
His only golden finger is that he retains his full rationality.
Here, humanity survives in the last fortress, Dawn City.
Beyond its walls lies an endless wilderness shrouded in eerie mist, home to countless terrifying, mutated monsters.
This world has no dazzling magic, only the cruel laws of evolution at the genetic level. Humans strengthen themselves by hunting monsters and extracting their cores, but evolution's final stage is the consumption of reason by bestial instincts, leaving them utterly transformed into monsters.
