Transmigrated to the 1950S to Help the Nation Trade for Supplies

Liu Ruyan, a PhD in materials science, unexpectedly gains the ability to connect two timelines, 2024 and 1950, through an ancient jade heirloom. She is no longer a mere observer of history, but someone thrust into the tide of the times to experience it firsthand. Starting with using modern medicine to save lives on the brink of death, she encounters the power of the state and transforms from a “passerby through time” into a “comrade of the nation.” With her help, a secret and efficient closed loop quietly takes shape: the state provides support, and Liu Ruyan purchases crucial supplies in the present day. She sends them to a 1950 ravaged by ruin and in desperate need of rebuilding, receiving in return not only gold, but also antiques that carry the legacy of civilization and strategic rare earths. These are then sold through special channels, and the funds flow back to nourish the fledgling republic. She brings more than supplies: she also carries “sparks of knowledge” from beyond their time. All future technology is systematically interpreted in a way that brings it down to a level they can understand, transformed into “technical nutrition packs” that contemporary scientists can digest and absorb, igniting the first sparks of independent innovation. Faced with outside skepticism and containment, Liu Ruyan and her comrades stay true to the strategy of “steadfast development.” They do not fight over short-term gains, quietly laying a solid foundation for industry, science and technology, and people’s livelihoods. With their strengthened bodies, they calmly meet each challenge, earn respect through sheer strength, and seize the opportunity to advance the integration of civilizations. When the ultimate test arrives, a sudden global catastrophe, the republic draws on technology and a sense of responsibility far beyond anything in history to shoulder the duty of safeguarding humanity’s shared fate. But Liu Ruyan’s journey does not end there. Standing before the space station window and looking back at her blue home, her gaze is already fixed on the boundless sea of stars.
