Rust Remnant Orphan

On the barren waste star with acid rain, neural anchor modification is the only bargaining chip for bottom orphans to survive, but at the cost of burning lifespan and overdrawing nerves. Lin has been imprisoned in the mining area since childhood, witnessing companions turned into consumables for dismantling parts by the Star Crown Senate. He barely escapes death by relying on a patchwork rust remnant machine. With no way out, he joins the Rust Remnant Mercenary Corps, using the broken mecha as armor and his remaining life as a blade. The aristocratic standard Crown Guard mecha crushes refugees? Then dismantle the top-tier military equipment for parts! The interstellar chamber repeatedly backstabs and cheats? Then trample the strongholds to seize survival resources! The Senate offers a bounty for a galaxy-wide siege? Then unite billions of bottom-level modifiers, fighting all the way from the waste mining area to the inner core star domain! What does it matter if life burns out? From now on, covered in rust iron, with a remnant life in hand, we will surely overturn the lofty and rotten throne of the Star Crown!
