In 1977, in Kaoshantun, international negotiator Lin Zhiyao transformed into Lin Wanxing, an orphan girl from decentralization who was forced to marry by her uncle and aunt because her father did not love her mother. She was framed for domestic violence as soon as she opened her eyes. With a few words, she manipulated people's hearts and killed the best, but she accidentally broke the enemy's plot to target the "reactionaries" in the east of the village.
That man, Lu Zhi'an, looked like a down-and-out old man, but in fact he was a national treasure-level engineer who developed national defense generators. The scar on his left hand hid his passion for scientific research, and he was taciturn but secretly protective. Lin Zhiyao used the diary of an educated youth as a weapon and used modern negotiation skills to resolve the predicament of the times: using micro-expressions to find out the insiders of the commune, relying on political rhetoric to resolve the crisis of criticism, and using local strategies to organize villagers to protect secrets.
Coarse grain cakes match the dilapidated house, and the kerosene lamp reflects the spy shadow. The two formed an alliance from roasting sweet potatoes late at night to jointly destroying enemy agent communication points. In the era of scarcity of materials, they used waste products to make equipment and used psychological tricks to overcome dangerous situations. Uncles and aunts repented, young people awakened, and the whole people formed a team to protect the country; cross-village cooperation and establishment of enterprises turned Guashan Village from a remote village into a benchmark for prosperity.
There is no golden finger in space, only the wisdom of step by step; there is no floating sweet pet, only the tenacity of helping each other. When the wave of educated youth returned to the city, and when orders from the capital were delivered, they chose to take root in the countryside, letting their original intention of serving the country with technology bloom in the fields, and letting the feeling of protecting their families and the country be passed on from generation to generation. This is a silent game hidden in the countryside of 1970, and it is also a legend of family and country written with sincerity and passion.
