What If Every Emperor Swapped Dynasties at Random?

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.
