In the cyberpunk colony "Deep Blue Nine" on the edge of Titan, Lin Shen, a former pharmaceutical analyst, runs a small pharmacy and secretly identifies the deadly drug "Stardust" for the black market. During an appraisal, he accidentally inhaled alien archaeal spores deep in the ice. His consciousness connected with the cultural heritage of 30,000 years ago, and he gained the ability to deduce the impact of ecology and drugs. As the colony fell into chaos due to drugs, Lin Shen and Su Xingwan, a geologist who traced the source of the raw materials, discovered that behind "Stardust" was not only an illegal experiment by a multinational group, but also an alien genetic library sleeping deep in the ice giant, waiting for its successor. The two are forced to deal with the encirclement and suppression of the pharmaceutical giant, the ancient mission of spore consciousness, and the boundaries of human ethics. The final choice they face is: destroy forbidden knowledge to preserve the present, or risk inheriting the weight of a civilization and opening up an unknown evolutionary path for mankind's deep space future.
