In 2749 AD, humankind's home planet Earth became the Death Star due to resource depletion and ecological collapse. The "Spark Project" carried millions of human consciousness and civilization fires, and sailed through wormholes into deep space on thousands of starships in an attempt to find a new livable home. Captain Lu Chen, as the youngest starship tactical commander in mankind, took charge of the flagship "Ark" and led the fleet to move forward hard in the unknown star field, but unexpectedly encountered the strangest civilization in the universe - the Star Skeleton Civilization. They have no entity and no territory. They use star skeletons as their nests and feed on the consciousness of intelligent life. They can parasitize, tamper with, and devour consciousness. They also possess a set of consciousness rules called the "Star Skeleton Code", turning the game of consciousness into a plunder of survival. Faced with the gradual encroachment of star civilization, the human fleet is in a desperate situation: the parasites are reduced to puppets, and the consciousness of those whose consciousness is devoured is turned into cold star bones. Traditional interstellar warfare is meaningless in the face of confrontation at the level of consciousness. Lu Chen worked with the fleet's psychiatrist Su Qingyan and the AI captain "Apocalypse" to decipher the underlying logic of the "Star Codex". Using the resilience of human consciousness as a shield and the spiritual core of civilization as a spear, they launched a life-and-death game in the consciousness dimension. While resisting the invasion of planetary civilization, they face the crisis of trust and ethical choices within mankind - should they give up part of their consciousness for the sake of survival, or should they stick to the spiritual essence of mankind and the bottom line of civilization? From the tug-of-war of consciousness at the edge of the star field to the ultimate showdown at the core of the star skeleton, Lu Chen leads the human fire to guard the glimmer of civilization in the cold universe, and finally uncovers the secrets of the origin of the star skeleton civilization, finds a way to balance consciousness and survival, and opens up a new world for mankind in deep space.
