The blasphemous experiments in the "Creation Gene" laboratory have torn apart Pandora's box. A catastrophic leak twisted the genetic weapon that was supposed to bring about evolution into a nightmare sweeping the world - a swarm of mutant snakes that proliferate infinitely and become crazy with bloodthirsty.
The prosperous city has become a hunting ground for flesh and blood. King cobras grind bones, vipers' neurotoxins induce madness, acid vipers dissolve flesh, and burrowers turn shelters into tombs. What's even more terrifying is that the snakes, under the control of the "snake mother consciousness", have shown terrifying wisdom and tactics, pushing humans to the brink of extinction.
Scientist **Levi** bears the original sin, mercenary **Jack** turns into a cold god of death, and medical student **Su Ting** grows up in a pool of blood. They traveled through the ruins swallowed by the snake nest, struggled against the dark rule of the survivor fortress (the "Butcher"'s living bait), and hunted down the mad doctor **Collins** who caused the disaster (he actually wanted to harness the power of the snake god).
This is a journey into the heart of hell. Facing fusion trolls, mental pollution and flesh lairs, the survivors paid the price with their lives. The final battle is not a celebration of victory, but a cry of despair. When the "snake mother consciousness" was severely damaged, the snake tide degenerated into wild beasts, leaving only ruins, trauma and wandering snake shadows in the world after the disaster. The fire of civilization sways weakly under the shadow of eternal terror.
