In the Great Northern Wilderness in 1968, Su Wanqing was a sick young man who could be bullied by everyone in the educated youth. He coughed and fell down when the wind blew, but on the night when he was pushed into the ice cellar by his best aunt, he activated the ancestral space! With spiritual springs to cleanse marrow, medicine fields to grow grain, and ancient medical secrets by her side, she has tempered her sharp edge. During the day, she is a weak and vulnerable little girl, and at night, she transforms into a mysterious doctor who treats illnesses and saves lives. Was your place back in the city robbed? She relied on her medical skills to make friends with veteran cadres, but she backhandedly ruined the reputation of the best. Did she trip up the educated youth and green tea? She borrowed space supplies to start a side business and made a lot of money; the retired captain Gu Yanshen wanted to take care of the "weak woman", but he repeatedly encountered her ruthlessness when tearing apart the best and her calmness when saving people - this sick beauty is not easy to mess with! From the Great Northern Wilderness to Beijing City, she used the silver needle as the blade and the space as the shield. While uncovering the truth about her parents' disappearance, she and Gu Yanshen went from testing each other to fighting side by side. Who said that sick beauties in that era could only be manipulated by others?
