For Someone Who Repairs Agricultural Machinery, It Makes Sense to Build a Mecha, Right?

"I'm just a farmer repairer. Is it reasonable to build a mecha?" Type: Hardcore science popularization / Dihualiu / Laughing until your stomach hurts Introduction: Police: "Someone reported you for privately manufacturing heavy arms!" Protagonist: "What an injustice! This is really a farm tool! Look at this mecha. It's painted with yellow paint and carries urea on its back. It's just a tractor!" Policeman: "Then why is it flying?" Protagonist: "The mountain road was bumpy, so I added a little ejection function to the suspension..." One sentence review: This is a top-notch novel in which the protagonist installs a nuclear engine on a tractor in order to save fuel, and installs a laser sword on a harvester in order to remove weeds. In the end, the Geneva Convention was forced to update the "agricultural provisions." Don't drink water, it's easy to squirt!
