Back in the late 1970s, Li Chunqiu woke up and faced a showdown with his fiancée Lin Qingxin, who had been married for three years just to use him to escape and return to the city. In his previous life, he endured regrets and did nothing. In this life, he is completely sober and refuses to be anyone's cannon fodder. He took advantage of the opportunity of the resumption of the college entrance examination to change his destiny, went to Yanjing alone, showed off his amazing medical skills in the factory hospital, specialized in treating difficult and complicated diseases, overwhelmed his arrogant colleagues, and became a miracle doctor in the industry from his son-in-law in the countryside.
