Steel Covenant

Three centuries after an apocalypse shatters the human world, Qiao An is demoted from the Combat Armour Academy’s honours class to the outer academy’s logistics class after failing a mech compatibility test. Burdened by enormous debt, the young man’s prospects seem bleak. Then Qiao An discovers that he has already bonded with multiple sets of top-tier Combat Armours. When asked to choose between black and white, he decides to take both, hoping the powerful armours will make earning money easier. Saving the world is not his concern—until he hears that doing so could erase all his debts.
