The Female Emperor of Great Jin Has Arrived, Everyone Get Out of the Way!

The drama-filled history of the Rebellion of the Eight Princes absolutely must not be forgotten.

The protagonist, a history buff obsessed with the Rebellion of the Eight Princes, transmigrates back to the Western Jin era and discovers that he has become Sima Zhong in his youth, except as a girl. As a result, the crown prince becomes the crown princess, and she gets the nickname Zhong'er. Jia Nanfeng, meanwhile, becomes a handsome man, even more striking than Pan An, who lived in the same era.

It's strange, sure, but with the crisis of the Rebellion of the Eight Princes looming, Zhong'er must grow into an empress of her age.

But...

Why is it that whenever she sees that Jia Nanfeng, all she can think about is cuddling, hugging, and snuggling?

She casually swore brotherhood with two guys, only to find out they're the very culprits behind the Five Barbarians' Upheaval?

They're supposed to be rivals for the throne, so why does he blush whenever he sees me? Could he have a crush on me?

Should we just treat this as a romantic comedy? There has to be a limit to how unserious this can get...

And yet the schemes have been set in motion long ago.

Zhong'er's path to becoming empress is still a long one.

(Pure romance, one-on-one, gender-swap transformation. She gets bewitched at the start and goes completely off the rails, then struggles to resist. After coming to her senses and weathering many trials, she ultimately becomes a little girl of her own free will.)

(Also: Many novels on this site turn the Three Kingdoms characters into girls. This story begins with Liu Shan's death, before Wu has fallen, so it can be seen as a continuation of those Three Kingdoms gender-swap stories.)
