Eight years have passed, and the quantum satellites that Yan Fei initially launched have reached nearly eight light-years from Earth. Through these quantum satellites, Yan Fei has mapped the terrain of all star domains within eight light-years of Earth.
Utilizing the wormhole traversal ability of the drone mothership, Yan Fei controlled the drone carrier to explore all stellar systems within an eight light-year range, gathering comprehensive data on these stellar systems. He even discovered two Earth-like planets in other stellar systems, which could be developed with some effort to become a second Earth.
