If hyper muscles isn’t your thing, then I suggest hitting the downvote button. Mean comments solve nothing.
The Unerian never actually got into aerodynamic research, their aeronautical technology diverged from the Zebras and went into the territory of large deadly flying battleships instead of airplanes. From this tech emerge the industrial application of using flying ships as cargo haulers, they are slower than airliners but have a way larger cargo space. Every day, the fleet of cargo ships flew back and forth, delivering containers across the continent and beyond.
Rarely, an airship does break down, that’s when a specialized towing service gets into action. But unfortunately, the nearby station was busy with their current task, the trading company then posted a job of helping tow the ship which, to their surprise, was taken by a single person.
This isn’t Fort’s first time hauling a very heavy object, but pulling a 100k tons ship for 10 hours straight does strain her a bit. Luckily, the nearest port town is just a short 3 days walking trip.
