When quantum entanglement accidentally breaks through the barriers of space and time, genius physicist Yan Weifu discovers that he can hear "echoes" from parallel universes. On one side is the war alarm in the cyberpunk world, and on the other side is the prophecy of annihilation of magical civilization. All disasters in time and space point to the same source - him in the real world. In order to prevent the collapse of the multiverse, he must travel through the gaps in time and space and collect mysterious fragments scattered in the long river of history. Every choice he makes creates unknown destruction and rebirth.
