As a professional in life professions, one often has part-time jobs in multiple fields, before specializing in one direction. Shipbuilders of floating hovercraft are not only required to master magic guided engineering and forging, but they must also possess exquisite woodworking skills.
Last comes the inflation device for the buoyancy airbags. Eteliria's buoyancy balloons are filled with high buoyancy and stable Guy Dust, making the inflation device essentially a type of magic guided reactor. With Fang Hong's current technology, he was not yet able to produce it and could only place orders. However, he still needed to learn some related usage and maintenance theories.
But he had no plans to directly learn the production technology for the inflation device, as he estimated their ships wouldn't need it in the future.
