Modern cardiac surgeon Shen Congrong traveled through time and became a substitute for Yaoyin and married into Prince Jing's palace. She soon discovered that Prince Murong Che's "rebirth from illness" was all a disguise, and the two of them were actually the control subjects for the human experiments of the madly criticized imperial doctor Baili Hui. With the help of modern medical thinking, Shen Congrong solved the drug traps, memory editing, poison manipulation and other conspiracies one by one, and formed a life and death alliance with Murong Che from mutual testing. They conducted in-depth investigations and revealed Bailihui's plan to seize eternal life using the royal family, generals, and medical clan as materials. In the end, the two teamed up to destroy the experimental core and eradicate Baili Hui in the decisive battle at the Imperial Tomb. Shen Congrong founded the medical school as a queen, promoted medical ethics, turned the once sinful place into a light of salvation, and together with Murong Che opened a new era of medicine that respects life.
