Dude can teleport to a location he sees on a shoddy map with a scale equivalent to (I'd estimate) showing the whole Europe and more. How the heck does that teleportation even work? I can only assume he simply needs an intention, a wish. Probably a deity interprets that intention and transports him to the correct place. Likely one of the most broken teleportation cheat skills I've seen in trash isekai so far.
