**The Rust Age: Thorns and the Starry Firmament**
Blood rain pours from the sky. Scarlet spores spawn hordes of bone-corroding beasts, and civilization collapses overnight.
The cold, world-weary bodyguard **Lin Wei (Thorn)** is mortally wounded saving her client, only to be injected with a lethal drug by the genius biologist **Su Wanxing**.
The “Twin Core” System forcibly binds them together: their lives and pain are shared, and if one is gravely wounded, they both die!
She resents this burden, yet is forced to feel the other’s midnight tremors;
The other feels guilty about this shackle, yet relies on her sharp edge to tear through the darkness.
From a chokehold standoff in a cold-storage room to fighting a mutated lord back-to-back,
From suspicion and exploitation to clasping hands to trigger the annihilation of civilization
They are each other’s “pathogen,” but also the only antibodies they have in their desperate plight.
As the beasts’ nest swallows the setting sun and conspiracies spread through the City of Gears,
Only a pact sealed in flesh and blood can burn away the apocalypse and rewrite the starry firmament
