The journey from the Magic Beast Forest to the Freedom Plains was quite long, especially if someone didn't have a virtual map of the entire Rare Plains like Jacob.
With Autarch's special trait of never being tired as long as it has a fresh host body and Jacob's own unique endurance, they both didn't need to rest as they could continue to move.
Furthermore, Autarch could continue to replenish its mana with a magic core like a battery and maintain both the speed and altitude of the Bronze Disc. Right now, they were traveling over 1000 miles per hour speed, and despite that air current, none of them seemed bothered by it because Autarch was also using a mana barrier.
