My Shadow Guard Is a Man in Disguise (Matriarchy)

Romance blurb:

Jiang Ruoyao transmigrates into a matriarchal world and becomes a spoiled imperial princess who bullies women and men alike.

The men she meets are either delicate beauties as frail as willow branches, or rugged men bent on killing her for revenge. The only exception is the "Shadow Guard Sister" at her side: cool and composed, busty with a slim waist, valiant and spirited, elusive, and highly skilled in martial arts... (Ten thousand words omitted here.)

Jiang Ruoyao isn't interested in handsome men. She only has eyes for her Shadow Guard, and loves cuddling up to her.

Until Jiang Ruoyao thinks she's become a lesbian and decides to come out to the world.

Not wanting her master to be misunderstood, the Shadow Guard finally tells the truth and kneels to accept punishment.

Jiang Ruoyao: "You say you're a man? Prove it!"

The Shadow Guard lowers his head in despair and slowly begins to undress.

Jiang Ruoyao's eyes widen at his perfectly proportioned physique and well-defined abs...

Jiang Ruoyao wipes away her drool. Maybe she does still like men!

Career blurb:

Jiang Ruoyao transmigrates into a matriarchal world as a spoiled imperial princess. She plans to lie flat and coast through life, but Heaven won't let her be a slacker.

The couplets and poems she recites offhand become famous across the land. The people she happens to save turn out to be a miracle doctor and the richest man alive. When she's exiled to the frontier, she unexpectedly improves the military's weapons and equipment. Even her former wastrel friends are inspired by her to make something of themselves.

She heads north to fight the enemy and south to control the floods. Though the royal family plots against her and her enemies surround her, she ultimately wins the people's support, finds love, and claims the world.

PS: The female lead has a golden finger throughout. She and the male lead return to the modern era, and there are no childbirth plotlines.

Theme: Persistence is the key to success
