Hilarious Body Swap: I'm Not a Woman, Am I?

Gender-Swap Stories

Completed stories where a woman transmigrates into a man's body or a man into a woman's body, with a huge contrast between their original and new identities.

Any Pure Wish-Fulfillment Stories?

Any Stories With Bonus Chapters About Future Generations and Generations of Emperors Watching From the Underworld?

I'm looking for books similar to With the Minister System in Hand, I Disguise Myself as a Man in Ancient Times (Rising to the Clouds, Imperial Exams). I mean stories where the dead emperor watches the next generation's development.
