In 2049, a mysterious stone piece unearthed from the Peking Man Site revealed the code of civilization spanning hundreds of millions of years. The spiral carvings on the stone flakes, the metal screws of Kaluga, the nuclear reactor of Oklo, the glass ruins of Mohenjo Daro... These are regarded as traces of "prehistoric civilization" by humans, but they are actually the "teaching materials" left by the alien sowers for the "star seeds".
Earth's ape-man ancestors touched Kaluga's screws, Homo erectus left spiral patterns on Oklo's pottery sherds, and priests 5,000 years ago sealed star core fragments in glass - every exploration is a test of "independent growth." When the synchronous orbit ring of the "Sea Foam" star was activated, and when the Sower's starship arrived, mankind finally understood that the so-called "prehistoric civilization" was just the foreshadowing laid by the Sower for the "Twin Civilizations".
The earth and "sea foam" are the two selected "seeds" in the universe. When the energy of their star cores synchronizes, when human genes merge with the wisdom of the sowers, a "reunion" spanning a billion years begins - not a conquest, not a replacement, but the symbiosis and rebirth of two civilizations.
Purpose: Through the settings of "Mystery of Prehistoric Civilization" and "Interstellar Twins", explore the essence of civilization which is inheritance and symbiosis
