Zhu Yuchi was hit by a transmigrator's emissary, a huge truck. The System told her that her signature skill had randomly rolled an UR-grade martial art: Mountain-Splitting Palm, which was perfect for the ancient world she was about to visit.
Zhu Yuchi accepted the setup that the System had bound her and would send her to various worlds to complete missions. The System was delighted and told her that if she completed her missions properly, the Main God could turn back time and send her to two hours before her death. It also said it was very powerful, and as long as its Host focused on the missions, the two of them working together would be invincible.
The System brought Zhu Yuchi to a dim little room and told her that her mission was to make the fated female lead of this world live a happy life.
Zhu Yuchi: So, who's the female lead?
System: See that luxuriously dressed woman in front of you?
Zhu Yuchi: Got it. It's her, right?
System: She's ambitious, and she'll enter the palace later. She'll eventually become Empress, but unfortunately, she still won't be able to change the fate of her daughter being sent away to marry for political reasons.
Zhu Yuchi: So, should I help her gain a foothold in the palace or stop her from entering it?
System: She'll be pregnant in a moment. The child is yours.
Zhu Yuchi: ...?
World One: [Power is a woman's best beauty treatment, so my daughter is destined to become Empress]
A cold-blooded general with exceptional martial skills X an ambitious Empress with a calculating mind. Together, they change the dynasty.
(Note: Because the System secretly arranged for a woman to give birth to a child, the female lead will disguise herself as a man. Her wife and daughter both know the truth, and a future-generation extra will reveal it to the world.)
World Two: [I met a rich woman on the road and became sworn sisters with her, then her daughter fell in love with me]
World Three: [A courtesan flees with her older sister's daughter, and I take them on a journey through the martial world]
World Four: [My subordinate brings me an orphan girl who was supposed to be silenced. I'm the leader of the Demon Cult]
World Five: [I rescue a girl who's being hunted and kindly take her in, but she wants to sleep with me]
Theme: Never say that women are not heroes
