In the distant future, mechanical civilization rises and mankind gradually loses its dominance over the world. Lin Chao, a young engineer, lives on the edge of the coexistence of humans and machines and witnesses the machine camp's continuous penetration and suppression of human society. Lin Chao's good friend Jin Yu has been committed to studying the coexistence of humans and machines, while Su Bei leads the resistance army and is determined to defend human dignity to the death. Xuan Mo, the core of the mechanical camp, promotes the "purification plan" of machinery to the human world in an attempt to establish a new purely mechanical society. Artificial intelligence Eve gradually awakened her self-awareness during her communication with Lin Chao, and began to question the extreme logic of the mechanical camp. Lin Chao and Eve join hands to try to find the possibility of reconciliation in the conflict, but are drawn into the vortex of the final showdown between machines and humans. Amid the intertwining flames of war and speculation, Lin Chao faced the most difficult choice: Put humanity first, or try to create a new order of coexistence? In the end, under the morning light, where will the fate of humans and machines go? With a fresh and elegant style, this book shows the warmth and tenacity of science and technology, and explores the boundaries and possibilities between humans and machines.
