From Concubine's Daughter to Legitimate Heir: Conquering the World with Space Treasures

Two-faced, clear-headed healer + aloof, tsundere, secretly passionate prince + marriage before love + sweet, satisfying revenge

Everyone knows how impressive it is when an ugly duckling transforms into a swan. Once she makes her stunning transformation, everyone is left in awe!

A medical PhD from the 21st century transmigrates into a book and wakes up in the body of an ugly, oppressed illegitimate daughter in ancient times. The husband she's forced to marry is on his deathbed.

She sheds her original body's cowardly, helpless nature, cures her husband's illness, rebuilds the family business, and tears apart her vicious half-sister and stepmother. In the process, she uncovers a mystery about her birth...

Unfortunately, her devoted yet cold-hearted husband still insists on divorcing her...

She was ugly, but after transforming her appearance, she astonishes everyone and her career soars.

She was weak, but her powerful space storage is packed with everything she could need, and her medical skills are unmatched. With a gun in one hand and ammunition in the other, she takes brutal revenge.

“What? They got back together?”

He once treated her with cold indifference, but now he clings to her relentlessly. Her stone-faced husband comes to his senses, falls head over heels, and turns into a devoted simp.

Was it a misunderstanding, or was there another motive?

The more determined he was to divorce her at first, the more miserably he chases after her later...

For the restoration of their country, they join forces: she wields a gun, he fires the cannons. Together they drive the corrupt emperor and his cronies from the palace and unite the realm!
