Spoiler

He manages to return back faster using a flying ship, however instead of his home, he finds a city. He finds out he's in the wrong era. He despairs not being able to get back and finds out that time travel back to his original era has a very low success rate, like below 1 percent. After dealing with something that happens immediately after, as thanks for his help dealing with it, the goddess? sends him back to his original era.

yeah, expected that after the city name was different than what he remembered.
Thanks for the spoilers
