Human Federation: My Infinite Avatars

With both parents reduced to conscription fodder, a bottom-tier youth endures to become a god-level technical officer. A system awakens, granting infinite respawning avatars at his command, sacrificing resources to exchange for black technology! His main body poses as a dutiful tool, while his avatars sweep through all dangers in the shadows. What if the transcendent powers hold sway? Behind the scenes, his avatars lay plans across the stars, and mortal technology will eventually topple the upper echelons! — Description from novelcodex.org
