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

[Chat group + many female protagonists] [Great and righteous and pure love warriors are not allowed to enter]
Lu Yun, who failed in both career and love, was pulled into a very special chat group.
"I traveled to the end of the world. Food is scarce here and I can't even get enough to eat!!"
"I traveled to a world of cold weapons. Although food, clothing, housing and transportation are not as convenient as on Earth, at least I live in a palace and don't have to starve every day."
"You are all so miserable. Fortunately, I traveled to a world of fiction..."
Lu Yun: "You all traveled through time? Why am I still on Earth?"
"You are on Earth? Is that true?"
"Handsome, I have a daughter on Earth. Can you help me see how she is doing now?"

"Brother, the biggest regret in my life is that I haven't been able to take good care of my parents. Can you help me take care of them?"
[Ding, you received a red envelope from the doomsday world traveler 'Su Chen'...]
"Brother, I'm leaving my wife and children on Earth in your care......"
Lu Yun: "........."...
