I Built the Mech for the School Beauty, Shocking the Scientific Community

Xuyang, a struggling student at Jiangcheng University of Science and Technology, is fired after being suspected of fabricating his graduation project. While guarding his grandfather's old repair shop, he accidentally awakens the Super God Repair Shop System. School beauty Li Sisi mistakenly orders a 50cm mech as a 500cm one due to a slip; Xuyang builds it on time using the system, but genius Yu Zihao steals the credit, and both are fired. Representing the school in the National Science Competition, Xuyang upgrades his mech and unlocks an atomic breath attack, stunning the audience, winning the competition, and clearing his name. Later, Yue Xing discovers rare earth resources. Xuyang builds a supersonic mech to compete, but Zhao Kun secretly sabotages it. Finally, Xuyang repairs the mech, launches a rocket to the moon in a hurry, retrieves the rare earths first, and becomes a new star in national scientific research.
