Travel Through the 1950S to Help the Country Exchange Supplies

Liu Ruyan, a female doctor of materials science, was accidentally given a dual-time and space ability connecting 2024 and 1950 by an ancient jade passed down from her family. She is no longer a bystander of history, but an eyewitness who is pushed into the current of the times. Starting from using modern medicine to save a dying life, she met the power of the country and completed her identity transformation from a "time and space passerby" to a "national comrade". With her help, a secret and efficient closed loop quietly operated: the state provided support, and Liu Ruyan purchased key materials in modern times; sent to the 1950s, which were in desperate need of redevelopment, in exchange for not only gold, but also antiques and strategic rare earths carrying civilization; and then liquidated through special channels, the funds returned to nourish the nascent republic. What she brought was not only materials, but also "tinder of knowledge" that transcended the times. All future technologies have been systematically interpreted through "dimensionality reduction" and turned into a "technological nutrition package" that contemporary scientists can digest and absorb, igniting the spark of independent innovation. In the face of external doubts and blockades, Liu Ruyan and her comrades adhered to the strategy of "development focus" and did not compete for shortcomings and gains, silently laying a solid foundation for industry, technology and people's livelihood. They use their strengthened "physical bodies" to calmly cope with challenges, win respect with their absolute strength, and promote the integration of civilizations. When the final test came - in the face of a sudden global disaster, the Republic shouldered the responsibility of guarding the common destiny of mankind with technology and responsibility that far exceeded history. And Liu Ruyan's end point is far more than that. Standing in front of the window of the space station, looking back at her blue home, her eyes have been cast on the boundless sea of ​​stars.
