Technology in the future interstellar world is developing rapidly, but the topic of time and space travel is still a taboo that people dare not touch. However, an inexplicable interstellar catastrophe is coming. In order to preserve human civilization, the Alliance has no choice but to use immature technology to send people back and forth in time and space to find the cause of the catastrophe. Who knows... This technology is too immature! Comrade Xiao Fang, the alliance's special commissioner, said that the time travel error is around a few thousand years. Who can withstand this? ? ? Forget it, little tricks don't work, roll up your sleeves and work hard! (Historical waste can only write history based on my mixed historical knowledge, please forgive me)
