I Traveled to a Collapsed World

[Slow travel + no cp + non-cool writing + relaxed + group portrait] [Time travel first and then fast travel, a new world of fast travel] Main protagonist group: [F-level silly and cute little system] + [Occasionally funny, sister-like host] + [Gentle and powerful god] (There is a male protagonist, but he is not in love. He focuses on helping his growth; there are many private settings, and any infringement will be investigated.) A sudden plane accident caused Le Sang to travel through time. She entered a small world that was about to collapse and be destroyed. She wants to return to her original world and rebuild the Wen family orphanage, but this seems to be an unattainable thing! Facing the most difficult super-risk mission in the fast-traveling world, and facing the protagonist group who are reborn, blackened, and have inner demons in the small world, where should Le Sang go? Stay or continue? Death, or challenge? Can she go back? Will she join the fast travel world? — "X277, why don't I have the memory of the original owner?" — "How could that happen? Why is the original owner still there?" — "A new star appears and everything turns around." — "Is the Great Collapse coming again?" — "Pfft, sister?" — "Red flag?" "Huh? That's what you're talking about!" As he gained a deeper understanding of the world of fast travel, Le Sang's previous obsession became smaller and smaller. What is the meaning of time travel? What is the point of the task? It seems that after seeing thousands of stars, I miss their brilliance even more.
