In a highly developed future world, technology has broken through the boundaries of human cognition. Artificial intelligence has become capable of independent decision-making, gene editing has become popular, and consciousness transfer technology has caused global shock. Winston Laing, a classical ethicist, was invited to participate in the review of the world's first 'Consciousness Transfer' project. At the crossroads of technology and ethics, his family dilemma with his daughter Leah, his ideological collision with the programmer Eve, his argument with Arthur, the chairman of the ethics committee, and his confrontation with the mysterious entrepreneur Seth, all together weave an unprecedented debate about human nature, morality and technology. After witnessing the miracles and disasters brought by technology, Winston gradually moved towards the fission of his mind. He must make a choice: stick to traditional ethics, or accept the reshaping of human nature by technology? The novel unfolds in a classical traditional style, deeply depicting the ethical crisis and human struggle under the torrent of science and technology, and finally reveals the true face of the future world in a global ethical trial.
