Yan Qingge, a top modern surgeon, died suddenly unexpectedly. When she opened her eyes, she became an abandoned concubine in the cold palace. She even had a death countdown that said she would die in three days. In order to survive, she saves people with a silver needle in her left hand and kills with poison in her right hand. While working as an "emergency doctor" for the prince, she plays psychological games with the sinister emperor.
"Your Majesty, you need an acupuncture for your headache."
"My beloved concubine's technique is very similar to the elaborate method used to assassinate me."
"Then you still want me to pierce it?"
"I'm curious, what tricks do you want to play this time?"
When the cold palace became her "Top 3A hospital", when the emperor went from being suspicious to being really favourable, Yan Qingge discovered that the death of the original owner was actually involved in a shocking conspiracy of the previous dynasty!
"I can save your life, or I can kill you."
"Your Majesty, do you want to cooperate? I'll treat the disease, and you'll kill the person."
The medical genius concubine × the suspicious and evil emperor, a counterattack from scheming against each other to fighting side by side!
