In 2135, ecological collapse sweeps across the globe. Li Qingyang, a young man from the countryside, is forced to move into an underground city. But after awakening a higher-dimensional perception ability, he is drawn into the Penglai Project, which will determine humanity's survival. As Earth's civilization uses space elevators and controlled nuclear fusion to reach for the stars, it discovers that the solar system has long since become the ruins of an ancient war between civilizations. When a fleet of three-body beings brings a warning of the universe's collapse, Li Qingyang pilots a starship equipped with wormhole technology and ventures deep inside a black hole to seek the key to reversing entropy. As an alien civilization tears open a wormhole and descends, he discovers that the starry sky he sees is actually a living neural network spanning the universe, and that the so-called invasion is merely an unconscious turn by a higher-dimensional life-form.
