In 2247 AD, human footprints have spread all over the solar system, but loneliness is increasing day by day. Humanity has never stopped exploring deep space, eager to find traces of extraterrestrial civilizations. A scientific research ship named "Pioneer", performing a long-term deep space survey mission, unexpectedly received an extremely weak but well-structured and obviously unnatural signal from the edge of the Oort cloud outside the solar system - "Abyss Echo". This signal is not a greeting, but like a huge, encrypted "data package", which contains fragments of scientific and technological principles that far exceed human knowledge, but is also accompanied by disturbing and difficult-to-decipher ideological information. The discovery of the signal source triggered shock and fierce debate among the top officials of the United Earth Government: Is this an opportunity or a gift from a higher civilization? Or is it a trap, a "poison apple" that induces humankind to self-destruct? The "Whisper Project" was launched. An elite team composed of top scientists, linguists, psychologists, and military representatives was convened to try to decipher the signal and determine human response. At the same time, the "technological seeds" hidden in the signals have quietly taken root and sprouted in human society, triggering technological explosions and social upheavals. However, the secrets and intentions behind the signal sources are far deeper, older, and more dangerous than anyone imagined. Humanity stands at the crossroads of leap and destruction, listening to the echoes of the stars and making the final choice.
