Genius engineer Jin Yan is reborn into the mecha era as the daughter of a poor blacksmith. With no spiritual energy, even piloting a mecha is out of reach? She insists on tearing up this rule through design, modification, and tactics. Sporting a cool yet cute face, she roasts a troublemaker's backside until it smokes; then drags along the sharp-tongued yet soft-hearted wealthy prodigy, turning the mecha squad into a massive, hilarious spectacle. Starting from the border star region, these youths charge all the way into the center of the storm. Coexisting with danger awakens super-S-grade spiritual energy, while identity mysteries and alliance conspiracies follow one after another. When the phantom beast approaches their homeland, she and her partners finally stop joking, piloting mechas to charge onto the battlefield—money can be remade, but the people behind cannot be fewer.
