He saw the signs of Earth’s impending doom a decade before it happened, warning the world of the catastrophe to come. But instead of being hailed as a savior, he was ridiculed, dismissed as a madman by his peers, and ignored by society.Realizing that nothing could change humanity’s fate, Xiao Yu made a decision. He turned his brilliance toward survival. Using knowledge decades ahead of human science, he constructed the first true interstellar battleship—not for humanity, but for himself.

To uncover the truth, he must push beyond the limits of human science. His battleship is just the beginning. Through relentless technological advancement, he will evolve, forging a warship that can traverse the stars, a fleet that can reclaim humanity’s lost legacy.The universe is vast, filled with unknown civilizations, ancient mysteries, and dangers beyond imagination. But Xiao Yu will not stop. He will find answers. He will ensure humanity’s flame is not extinguished.The journey into the unknown begins now.
