In the previous life, the golden lawyer Jiang Zhixia died unexpectedly. Once she traveled through time, she became the stupid girl of the village head's family in the 1970s whose IQ was stuck at eight years old. There is a brother who is honest but protective of his shortcomings, and a sister-in-law who is gossipy and makes trouble. Life is like a wild goose chase. Just as she was preparing to slowly cure her "idiot", a marriage contract letter from the Beijing Military Region came down, asking her, a "little fool", to go to the city immediately to get married! The target is the famous, cold-faced and iron-blooded "Living King of Hell" in the military compound - Gu Yanshen, the third son of the Gu family. Sure enough, Gu Yanshen broke the engagement in public, making her lose face. The whole compound was waiting to see her being driven back to the countryside in despair. Unexpectedly, Jiang Zhixia neither cried nor made trouble. With a smile on her face, she turned around and hugged the thigh of the commander of the military region, sweetly shouting "godfather!" The marriage ended, but she moved into the Gu family compound as her goddaughter and became "brother and sister" with him. Where is the fool you promised? But watching her calmly solve the problems in the compound, stunning everyone with her fluent Russian, and even winning the provincial top prize after resuming the college entrance examination... Everyone was dumbfounded. Gu Yanshen, who had refused to marry at the beginning, was filled with regret. At night, the man cornered her in a corner, his eyes were scarlet and his voice was hoarse: "Xia Xia, I was the bastard back then. Don't call me brother, call me husband. I will give you my life and all my allowances..."
