Xia Yan, a modern medical genius, accidentally died in a surgical accident, and her soul was selected by the mysterious "Wanjie System". The system told her that if she wanted to get a chance to be reborn, she must travel through countless novel worlds and complete the task of correcting her destiny. As a price, she will lose all emotions and become a pure "task performer". When she first entered the system, Xia Yan completed her tasks with a calm and efficient attitude. By relying on modern medical knowledge and the skills provided by the system, she shined in various worlds. However, in the world of anti-war medical heroes, she encountered a turning point that changed everything - the original protagonist of this world "Lin Mo", an anti-Japanese hero with both medical skills and chivalry, was supposed to sacrifice himself to save the entire village, but survived because of Xia Yan's intervention. Lin Mo's tenacity and sense of justice touched Xia Yan's frozen heart, making her begin to question the true purpose of the system.

Xia Yan must find a balance between love, mission and self-salvation, while fighting against the "cleaners" sent by the system - those former missionaries who failed and were completely controlled by the system. …
