Cornerstone of the Lunar Sea: Beyond the Light Cone

China's "Guanghan Palace" lunar base is hidden deep in the lava tube at the bottom of the crater. Chief engineer Chen Fan's team secretly developed the light speed engine, but encountered hundreds of failures in ten years. The lunar surface experiment resulted in serious injuries to three colleagues. A well-planned "meteor shower" attacked the base, and confidential data was almost stolen. When the engine core was ignited for the first time and the blue light that distorted time and space swallowed the laboratory, Chen Fan saw the smiling faces of his sacrificed colleagues in the turbulence of time and space: "Don't stop, move forward."
