Three hundred years after the apocalypse, humanity survives in a shattered world where giant mechs and powerful Combat Armours determine one’s status, strength, and future.

Qiao An, a student from the prestigious Honours Class of the Combat Armour Academy, seems destined for failure when he flunks the crucial mech compatibility test. As punishment, he is demoted to the logistics division of the academy’s outer campus—a humiliating fall from grace.

For someone already drowning in debt, the future looks bleak.

But fate has other plans.

Qiao An soon discovers an unbelievable secret: he has already formed bonds with multiple top-tier Combat Armours, an achievement considered impossible by conventional standards. While others struggle to synchronize with even a single suit, he possesses compatibility with several of the strongest armours ever created.

Faced with a choice between two legendary armours, his answer is simple:

“Why choose one when I can have both?”

With overwhelming firepower and unparalleled potential at his disposal, Qiao An’s priorities remain surprisingly straightforward. He isn’t interested in becoming a hero, saving humanity, or carrying the hopes of the world on his shoulders.

He just wants to make enough money to pay off his debts.

Unfortunately for him, possessing the world’s most powerful Combat Armours tends to attract attention. As conspiracies emerge, enemies gather, and the fate of humanity hangs in the balance, Qiao An finds himself dragged into conflicts far bigger than he ever wanted.

But when someone mentions that saving the world might erase all his debts…

Well, perhaps being a hero isn’t such a bad deal after all.

Combining post-apocalyptic sci-fi, powerful mecha battles, humor, and an unwilling protagonist motivated more by financial freedom than justice, the story follows Qiao An’s rise from a disgraced student to a force capable of changing the future of humanity.
