Apocalyptic Mechanical Expert Wearing 70'S

Yu Qiuwan was in the 1970s without any identification. He was suspected of being a spy and was taken into a detention center. Facing the serious and handsome young officer, Yu Qiuwan said: "I can prove that I am not a spy." Yu Qiuwan was born in the apocalypse and is an expert in machinery. She didn't expect that she would travel back to the 1970s. This world is very beautiful, the sky is blue, the air is fresh, there are no ferocious beasts, no zombies, and no mutated flowers and plants that will strangle and devour humans. Especially, the food here is delicious. Yu Qiuwan embraced this beautiful world: "I like it here so much!" What? The country is lagging behind, and there are still enemies lurking outside? It doesn't matter, what she's best at is mechanics! Purpose: Work hard for a better future
