In the wasteland where the old world government collapsed due to the impact of "super evolution", the law of the jungle is the only law. The blood of super-evolved people has become the most precious resource, and it also breeds endless greed and danger.
Sayig, codenamed "Beast King", is an animal super-evolved person who survived the hellish laboratory on earth. His powerful strength and deep-rooted distrust of human nature are his weapons for survival. Iris, codenamed "Flower Doctor", looks innocent and pure, but in fact he is a plant-based madman who uses black market serum to gamble on evolution and is obsessed with power. His superb medical skills and top-notch lies are his perfect disguise.
The two people, who were supposed to have nothing in common, were forced to tie up because of a hunt for super-evolved people and a conspiracy by non-academy radicals. From a temporary alliance that was vigilant and exploitative of each other, to a twisted and solid bond forged in life and death battles. They will travel through dangerous ruins, fight against bloodthirsty predators, crazy pursuers and terrifying mutant monsters, and explore the truth behind the "blood of evolution".
This is an apocalyptic journey that begins with betrayal and exploitation, but ultimately leads to a revolution that subverts everything. The combination of wild beast nature and extreme madness will tear apart this decadent doomsday with absolute power, and jointly create their new order and throne on the ruins.
Purpose: In a completely collapsed world of the weak and the strong, explore the true definition of "power" and the price of "order", and ask whether the old cycle will be repeated on the ruins of destruction, or whether a new law can be born that respects life, accepts heterogeneity, but is strong enough.
