An incorrect prediction by the system caused a rift in time and space, and people's lives were in chaos. Some people opened the toilet door and entered ancient times. People realized that this was not as simple as the time travel described in the novel. They called this unprecedented chaos the "time and space effect." In order to solve this problem, the system handed over the nine detected space-time fragments to two members to go to different time and space to find them, and there was still one remaining fragment. Outside of the system's detection, their story officially began... "You will go home, but I will stay here forever." We are all running towards heaven, and we are all running towards the opposite hell - "A Tale of Two Cities"
Purpose: Humanity and the earth are a community with a shared future
