Chu Changge could sense his own world, so he knew this wasn't the Second World.
Gu Mian guessed this was probably Exile World.
Exile World was the world designated "2" among the seven, with a low degree of alteration, quite similar to Earth.
The 'brother' whom the Holy Daughter had introduced to him belonged to this world.
This time, Gu Mian had brought his own brother along as well, but unfortunately, all the latter could do was call out for his "sister," providing no valuable information.
At that moment, his brother peeked his head out from the CD, looking at Gu Mian's phone screen, much like a parent checking if their child was secretly dating. Gu Mian pushed him back in.
Gu Mian's love interest hadn't sent any messages yet. Chu Changge's phone, however, was constantly ringing with messages from his chat partner.
So Keke and Gu Mian both leaned in to look at his screen.
[Xia Yutong]: Hello, are you Chu Changge? Nice to meet you, I'm Xia Yutong.
