Traveling Through Ancient Times: I Went from Blue Star to Interstellar

(Alternative history + time travel + space + satellite + thermal weapons + daily farming + later exploration of the universe) Traveling through time, holding technological space in hand, settling down, sending satellites into the sky, shocking everyone. Just imagine, what would it be like to see the subway running across the ancient land? The war drums are beating, let me activate the navigation first, put the low-Earth orbital gun in position, and the heavily armed army is ready to fight! Such equipment seemed to be enough to fight aliens in ancient times, but don't forget, I just want to enhance Blue Star's fragile protection. On the interstellar battleship at the bottom of the trench, what kind of civilization is the "Poseidon Project"? Those space territories have charming scenery and arouse people's imagination. Everyone was shocked and asked: "Do you intend to conquer the universe? But they..." Lin Jiang replied proudly: "How can we live a mediocre life after time travel and rebirth?"
