"The Great Tang Chang'an City?"
"Really from that galaxy that looks so barren?"
"It seems so."
"Oni, quickly check what they've written in their letter!"
"Don't rush, don't rush! Daisen, you need to understand, from the Milky Way to here, at normal spatial speed, it takes about four hundred years of travel. That means they wrote the letter to us four hundred years ago; why are we in such a hurry now?"
"Well, that's true too, but I'm still too excited! New friends, Oni, new friends!"
"Alright, it's already been fully received. Let's take a look at the friendly letter from this new friend. Our neighboring Milky Way finally has someone we can communicate with."
"Yes, that little blue orb is too weak, it can't even pick up soul wavelength signals, can't receive our channels. Otherwise, if they could communicate, we could provide some technical support to each other."
...
Their civilization seems quite friendly.
