Starbound Puppeteer: I Turned My Mecha Into Living Weapons

Yan Nuo stares at the memorial wall—twenty-something brothers, all heroes who died defending the empire. Now it's her turn at the military academy, except she's got one fatal flaw: no special abilities. In this interstellar age where power is everything, she's just another expendable nobody. But when ancient puppet cultivation techniques merge with cutting-edge mecha technology, Yan Nuo discovers she doesn't need to be a hero—she just needs to turn her war machines into an army of one. The empire wanted a soldier. They're getting a legend.
