In the Iron Dome City, a Victorian city filled with roaring gears and filled with steam, the mechanical engineering genius Edwin Gearhandle and the aloof star of the Alchemy Academy, Claire Stardust, accidentally became connected due to a laboratory accident. In order to optimize the college's core steam engine, which was on the verge of being scrapped, they abandoned their sectarian views and magically combined the cold gear array with the shining alchemy array to create a subversive "ether engine." However, the "entropy energy conversion equation" at the core of the engine has attracted the covetous attention of the "Yinhui Chaebol" who monopolizes magical energy. Conglomerate heir Leonard Yinhui used patent infringement as a weapon to try to stifle this innovation. Faced with the high walls of technological monopoly and the doubts within the academy, Edwin and Claire must work together to deal with the rust-stained workshop and the parchment-covered courtroom. They not only need to improve the engine, but also challenge outdated rules and promote the formulation of an unprecedented "Cross-border Technology Patent Sharing Agreement". In the symphony of gear bites and twinkling stars, they will ignite the fire of a new era of integration and sharing for Iron Dome City. This is a passionate journey where robotic arms dance with magic wands, and patent documents compete with steam wrenches.
