The Prince Wants a Kiss, but His Princess Only Wants to Build a Career

I'm a military doctor in a special forces unit in the 21st century. After an explosion, I transmigrate into the body of the second daughter of a concubine in an ancient prime minister's household. Framed by her stepmother, I'm forced to live in the countryside for ten years. At long last, I'm brought back to the capital, only to find that my father doesn't care for me, my stepmother doesn't love me, and my sisters are all vicious beyond belief. Having transmigrated once, I refuse to live as spinelessly as the original owner of this body.

They say I can't practice medicine? Then I'll open clinics all over the world.

They say I'm too weak? I'll whip you until you're crawling on the ground.

They say I have no money? I'll build my own business empire.

The girl who was bullied all her life transforms into the most sought-after young woman in the Great Zhao Dynasty.

I only wanted to focus on building my career, so can someone tell me what this marriage proposal is all about?
