Genius Mage! Crushing the Trash-Tier World with Higher-Dimensional Power

"I can fly." If you don't understand what that means, let me put it this way: in a world of low-level fighters hacking at each other with swords, I can dominate from above like a plane against mules and horses!

In my previous life, I was an ugly good-for-nothing nearing thirty. Now I've been reborn in another world, a place where both science and magic have developed at an extremely sluggish pace. Here, a mage who can cast a "Fireball" is hailed as a great mage, while I was born with a talent for flight magic! That means I can enjoy the advantage of a plane attacking the ground in an age of cold weapons!

What exciting adventures await a mage with such a talent in another world? Will he carve a path of utter victory through his new world, or choose to live a quiet, ordinary life?

As he lies on his deathbed, holding his beloved's hand, will he be able to say, without regret, "I have lived my life with no regrets"?
