Sewer Rat Evolution : Book One: A Monster Evolution LitRPG
They flushed him like garbage. They should have made sure he was dead.
Subject R-1T was a failure. A lab rat injected with experimental arcane energy that was supposed to kill him. Discarded by cold, clinical mages, he was tossed down a disposal chute into the city’s fetid underbelly.
But the experiment didn’t kill him. It changed him.
Awakening in the toxic darkness of the sewers, R-1T finds he is no longer just a rat. A blue interface hovers in his vision, a System that rewards the strong and devours the weak. To survive, he must embrace his new
Hunt. Consume. Evolve.
From venomous slugs to hive-minded drones constructing a terrifying empire in the deep, the sewers are teeming with predators. R-1T starts at the bottom of the food chain, but he doesn't plan on staying there. Every kill brings new Biomass. Every level brings new mutations.
The Arcanists thought they were disposing of trash.
Instead, they were forging a monster.
Don't miss the start of this Monster Evolution LitRPG series!
Experience a gritty, "Weak-to-Strong" progression fantasy featuring a non-human protagonist, stat-heavy character building, and a visceral struggle for survival.

It’s fun, but lacking in substance. A little bit of worldbuilding between the action scenes would have been nice.
