Lin Yuan, 28, was an engineer at the National Deep Space Exploration Bureau, but disagreements over principles pushed him to the sidelines. As Earth's resources ran dry, humanity entered an era of large-scale space development, with the Interstellar Alliance leading the construction of an infrastructure network across the solar system. Stationed alone at an abandoned space station, he unexpectedly binds to an “Infrastructure Sign-In System.” Sign in each day to unlock modules of cutting-edge technology: energy cores, automated mining machinery, suborbital engines… No one knows that he is quietly reshaping the interstellar order. Western corporations monopolize technology, pirates ravage the trade routes, and the first lunar base is on the verge of falling. He has the System, but no support. Should he quietly build supply ports and logistics hubs, becoming the power behind the scenes? Or should he step forward and weave a smart network across the stars all by himself? Beneath the red flag, a silent infrastructure revolution is spreading through deep space.
