[Post-apocalyptic wasteland + divine corruption + illness leads to godhood + king of monsters]
When the apocalypse struck, Lin Guan was still unconscious in a hospital room. The authorities evacuated the survivors, taking those who could walk and those who could be of use, but leaving him behind in the fallen city because he wouldn't wake up. When Lin Guan opened his eyes again, the city outside his window was already dead, and his mother and younger brother were nowhere to be found, their fate unknown.
Everyone thought that strange illness had ruined Lin Guan. But after a mysterious higher-dimensional force corrupted the world, he learned that his illness was the key to understanding it.
Anyone else who comes into contact with it is dragged into monstrosity by fear, obsession, and attachment to loved ones. Lin Guan, however, can read the traces it leaves behind and claim the authority that belongs to him. He uses that power to cross the dead city in search of his family.
Those who once protected humanity have been warped into monsters by corruption, but Lin Guan carves out his own path.
Facing cannibalistic monsters mutated by the apocalypse, he uses his authority to cow all who stand before him. Years later, the truth comes to light, and the struggle for authority begins.
The beings the world calls monsters take their place behind Lin Guan.
Seated upon his throne, Lin Guan looks down at the people and monsters slaughtering one another for power. Blood blankets the land, and cries of anguish reach the clouds. But in the eyes of a god, they are no more than ants fighting over food.
“Gods never care.”
Abandoned at the end of the world, what do you mean, I'm the King of Monsters?
