The Heroine: Shen Xi. A world-class surgeon in her past life. Betrayed by her family, she is reborn into her 18-year-old self. She uses her knowledge of future medical breakthroughs and elite surgical techniques to crush her enemies. No "magic"—just pure, god-tier skill and a photographic memory for patient records.
The Hero: Mu Feichi. The Young Marshal of the capital. He is cold-blooded and suffers from severe insomnia and chronic pain due to old battlefield injuries. Only Shen Xi's specialized "Deep-Tissue Stimulation" (acupuncture) and her presence allow him to rest.
