Miscalculation
Editor: Henyee Translations
Vampires were known to be the second fastest intelligent creatures. The first were, undoubtedly, the dragons.
The Mages, with Wind Soaring, could only fly 35 meters per second, and around 126 kilometers per hour, which was very fast in this world where transportation was inconvenient, although the spell was flawed in that it cost tremendous magic power and required a day of rest for two hours of flight.
The bat form of the vampires was much better. They could fly 50 meters per second, or 180 kilometers an hour. More importantly, the bat form was just one of their many shapes and did not consume anything. They could fly for a whole day as long as they had enough stamina.
While the dragons were faster than them, the dragons were too big and had a low acceleration, and they were not as agile as the bat form of vampires at low altitude.
Therefore, vampires were all very confident about aerial warfare.
