I Hope This Trip Will Eventually Reach the Stars

Gro passed through, Traveling to a planet that has stopped rotating, half of it is a lava ocean with rolling magma, and the other half is a hard glacier at minus 200 degrees. Extreme heat and extreme cold alternate slowly on the planet on a year-by-year basis. The remaining humans can only ride on the "flying city" and struggle forward on the "twilight line" surrounding the planet. Fighting against heaven and earth, internal and external troubles. Gro passed through crisis after crisis until: "I just became invincible. Did you tell me that the interstellar trade fleet has arrived?" ——PS: To put it simply, it is an interstellar road article
