Parallel Traceback

In the future, with the degradation of human spiritual civilization and the birth of advanced beliefs in the autonomous consciousness of general artificial intelligence, the world will fall apart and a small number of humans will embark on the evolutionary path of biotechnology. Beitang Shi, who died in the doomsday world, had his consciousness transported to the eve of the doomsday three years ago, but his fate of restarting did not follow the original trajectory. An ancient organization controlled Beitangshi's destiny long before he was born. Not only that, many people in this world were created like him, and even their autonomous consciousness is just one of the functions of the brain. In order to investigate the purpose of their creation and the truth behind this world, they constantly travel through time and space through consciousness transmission between the future world and the yesterday world, looking for hidden clues. Traveling through time cannot change the past, it only brings derivative parallel worlds. The future is a world of artificial intelligence? A biopunk world? Or is it the world of virtual reality... Or maybe all the present and future are a retrospective across time and space.
