Xiao Yu faced an unavoidable truth: humanity's extinction was certain. Refusing to surrender, he channeled his genius into a singular mission—building the first true interstellar battleship. When civilization crumbled, he transcended his mortality, merging his consciousness with the ship's core systems and vanishing into the cosmic void. As the universe's last heir to Earth's legacy, Xiao Yu hunts for answers. What destroyed humanity? Was annihilation inevitable, or did darker forces orchestrate the end? His quest demands breakthroughs beyond known science. The battleship transforms into an instrument of evolution, spawning advanced warships and armadas capable of charting the stars and reclaiming what was lost. Across infinite space, unknown civilizations guard ancient secrets while cosmic horrors lurk unseen. Xiao Yu presses forward, driven by one imperative: uncover the conspiracy behind humanity's fall and reignite civilization's dying flame. The void awaits. The answers he seeks lie among the stars.
