In the time-traveler chat group, am I the only one on Earth?

[Chat group + multiple female leads] [Not for those who prefer righteous and pure love stories]
Lu Yun, who has failed in both her career and love life, is pulled into a very special chat group.
"I've been transported to a post-apocalyptic world where food is scarce and we're starving!!"
"I transmigrated to a world of cold weapons. Although the food, clothing, and shelter are not as convenient as on Earth, at least I live in a palace and don't have to go hungry every day."
"You're all in such a terrible situation. Luckily, I transmigrated into a novel world..."
Lu Yun: "You all time-traveled? Why am I still on Earth?"
"You're on Earth? Really?"
"Handsome guy, I have a daughter on Earth. Could you help me see how she's doing?"
[Ding! You have received a red envelope (1000 taels of gold) from Li Susu, a time traveler from the Great Xia Dynasty.]
"Dude, my biggest regret in life is not being able to take care of my parents. Can you help me take care of them?"
[Ding! You have received a red envelope from Su Chen, a transmigrator from the post-apocalyptic world...]
"Brother, I'm entrusting my wife and kids on Earth to you..."
Lu Yun: "........."
