In 2187 AD, the "Great Silence" came - all faster-than-light communications in the galaxy were suddenly interrupted, and the interstellar colonial empire fell apart. Lin Ye, the former chief data analyst of the empire, accidentally activated a "star code" from a prehistoric civilization on an abandoned space station. The code not only repaired communications, but also revealed a shocking truth: the "Great Silence" is a "screening mechanism" for higher civilizations to target lower civilizations, and human civilization has long been marked as a "target to be eliminated." In order to restart the interstellar connection and reveal the truth of the screening, Lin Ye united the exiled remnants of the imperial fleet, the rebel planets that mastered biotechnology, and the AI consciousness hiding deep in the network to form the "Restarter Alliance" that spanned races and positions. While avoiding the pursuit of the "Scavengers" of advanced civilizations, they deciphered the civilization code in the star skeleton code and searched for a glimmer of hope for the survival of human civilization in the ruins and sea of stars. However, they discovered that behind this screening, there was also hidden a billion-year grudge between prehistoric civilization and advanced civilization, and humans were just the most unexpected "variable" in this cosmic chess game.
