For Duanmu Huai, this scene was all too familiar.
Accompanied by the clanging of metal pipes and footsteps, one monster after another, with Alien-like heads and four arms, leaped down from all directions. They opened their large mouths filled with sharp teeth and let out a blasphemous roar and curse—they were the Genetic Thieves, one of the Alien creatures most deserving of extermination in this world.
The Genetic Thieves were one of the notorious units of the Tyran Insect Race, the most troublesome and annoying infiltration units for players, simply because... these things really could infiltrate everywhere.
Moreover, they were extremely adept at camouflage and could even spend hundreds of years gradually dispersing into human crowds.
