Cannon Fodder Female Supporting Role? I Turned Around and Joined the Army to Serve the Motherland.

Shen Niannian was originally a top materials scientist in the 21st century. After she died from overwork, she passed through a period novel and became a cannon fodder female supporting role who was about to be sold to a fool by her family in exchange for a bride price. In order to save herself, she quickly found Fu Yan, a cold-faced military officer who came to Beijing for vacation, and offered to marry him to join the army on the island, and by the way, she could become a stepmother for his two orphans who were martyrs. Shen Niannian returns to the 1960s with the defense scientific research space. She doesn't hang around men, she looks like a weak stepmother on the surface, but secretly she is rubbing nuclear submarine materials on the island. Everyone was waiting to see the delicate Shen Niannian crying on the island and being tortured crazy by two little devils. As a result, she went to the island, and she used Mathematical Olympiads and small physics experiments to control the two little devils into submission. They chased after them and called them "Fairy Mom". And the unsmiling Captain Fu returned home at night and found that the drawings drawn by his wife turned out to be the formula for special steel that the country was in urgent need of! When the border waters were deterred by foreign enemy aircraft carriers, the country fell into a technical blockade. Shen Niannian took out a stack of blueprints from his apron pocket: "Honey, don't panic, I've made a new submarine anti-radar coating material." Fu Yan looked at his frail daughter-in-law who couldn't take care of herself, and silently gave a military salute.
