Galaxy Zero

Lu Yu thought he was just repairing an electron microscope that was burned by a student. Until the charred lithium-sulfur battery residue revealed atomic coordinates that perfectly matched the "Book of Mountains and Seas". Four billion years ago, humans once unified 60% of the Milky Way and called themselves the Ancestral Ape Civilization. In order to avoid a dimensional cleansing called "optimization", we extinguished the divine fire with our own hands, demoted ourselves to beasts, and turned the solar system into a cradle of forgetfulness. Now the cradle is broken. In 2085, the human fleet left the solar system for the first time, and the hunters of level four civilizations have been waiting in deep space for four billion years. They were the chief culprits of the division of the empire, the descendants of feuding people, and the frightened birds guarding the cradle. The piece of scrap in Lu Yu's hand is the key to awakening everything. This time, there is no shield, no escape. Either learn to fly again or be completely annihilated.
