I'm the Dying Emperor's Doctor

Once again, Serina has failed to prevent the Emperor’s death.
“Why? Why does he keep dying every time?!”
Executed for failing to save the Emperor as the palace physician, Serina awakens to find herself in her third regression. Forced to return to the palace, she faces the same deadly dilemma:
Refuse the position as Imperial Physician? Execution. Fail to treat the Emperor? Execution.
Determined to change her fate, Serina resolves to speak her mind this time. To her surprise, Emperor Ajade willingly appoints her as his personal physician.
“Fine. This time, I’ll save you no matter what it takes!”
Can Serina finally defy the odds, save the Emperor, and retire peacefully from her treacherous role as palace physician?
