After the nuclear explosion, civilization returned to zero. The useless commander Cheng Xiao, who had been spurned by the entire army, became the only person who could awaken the 'Shou Sui' AI. The survivors begged him to restore order, but he just wanted to wait quietly for death. Until psychiatrist Lu Zhao discovered that he could understand the whispers of AI, the orphan Ah Qi could touch the memories in the data, and the rebel general Black Crow was leading an army to encircle and suppress them. When Shen Yuan's robot began to self-destruct and Lao Ji's suicide note was burned, Cheng Xiao finally understood: It was not that he wanted to restart civilization, but that civilization was waiting for him to learn why some people were willing to shed tears for their enemies.
