Final Fantasy from the Beginning

The general plot is about the male lead transmigrating to a cultivation world. Since the missions are too urgent and too difficult, he tackles dungeons instead. In other words, it's a fresh start in another world. I'll figure out the rest later. There's Miku, though, and there definitely won't be a huge harem, so fans of harem stories can skip this one.
