I Become an Immortal in the Great Ming During the Hongwu Era

Novels Where the Protagonist Is the Only One With Magic in Ancient Times and Is Mistaken for a God Among Mortals

I’m looking for a story where the protagonist is the only one with supernatural powers, and people in an ancient setting or another world mistake them for a deity.

Any Books Like Transmigrated to the Ming Dynasty to Take the Imperial Exams?

I want a book with solid, realistic research and a well-built, believable historical setting. It can be about transmigration or being reborn, as long as the golden finger isn't too outrageous. I'm a history student, and I can't stand plots that are too ridiculous or cringeworthy. They make me uncomfortable the moment I read them.
