A mysterious virus sweeps across the globe, rewriting the rules of evolution for all life. Human civilization rapidly collapses beneath the overwhelming superiority of size and strength, and Earth enters an unprecedented era of giant beasts!
As humanity struggles to survive amid the ruins, he discovers that he has become an insignificant little caiman in a swamp. No spiritual energy, no alien technology, only the most primitive and brutal laws of nature: survival of the fittest, and limitless evolution!
From the moment he devours his first young fish, there is no turning back. His thick hide hardens into Dragon-Scale Heavy Armor, tougher than alloy; his short limbs evolve into Abyssal Claws capable of tearing apart the earth; and deep in his primitive brain, the Crimson Vision of a predator ignites...
The King of the Swamp is only the beginning. When his colossal shadow begins to blanket the rivers, when he strides across the continental shelf and roars at the ancient leviathans lurking in the ocean's depths, an age ruled by a cold-blooded emperor will finally begin!
“They say humanity is the spirit of all creation.”
“But now...”
Beneath the deep water, golden vertical pupils slowly open, and a mountain-sized back breaks through the sea.
“I am the calamity.”
Why should the protagonist be changed?
