The System Wants Me to Earn Lifeforce

Su Zeze, a genius doctor from the 22nd century, disrupts the space-time System and arrives in an era of martial arts.

She wakes up covered in wounds and is called a princess consort. The man who has her thrown into prison turns out to be her own husband, the regent.

Even worse, her husband is involved with her older half-sister. As the legitimate daughter, she is too frail to practice martial arts and can only study medicine.

To make matters worse, she has to earn points by treating and saving people, then exchange them through the space-time System for more life. Every day, her life is in danger.

Fortunately, the space-time System can grant her anything she wishes, allowing her to treat and save people in this other world. Since her personality is completely different from the original owner's, the regent finally begins to see her in a new light, and the two fall for each other.
