Piece after piece of medical information flowed through the Tianji megastructure. The Collectors that made up Tianji communicated with one another about this information, analyzing the connections within it.
Through this, the Collectors gained a deeper understanding of the Hui civilization, an ancient civilization that had been destroyed eight hundred million years ago.
Back when it had conducted large-scale civilization experiments, the Hui civilization had divided its many laboratories into upper, middle, and lower tiers. There was no hierarchy between the three; their configurations were identical, and only the technological levels of the experimental civilizations they oversaw differed.
Lower-level laboratories were responsible for planetary civilizations that had not yet entered space. Mid-level laboratories oversaw civilizations capable of building spacecraft, while upper-level laboratories were responsible for civilizations capable of interstellar travel.
Because the development of civilization technology formed a pyramid, with more advanced technology being harder to develop, civilizations could destroy themselves, regress technologically, or stagnate for various reasons during their development. Thus, the number of civilizations dwindled the higher their
