According to the Big Data Search, "Gu Mian's closest friends and beloved family" should be at this location.
At this moment, Gu Mian is in a classroom, fiddling with a device in his hand that looks like a mobile phone.
This is Xiao Qiao's Big Data Search; you input the thing you want to find, and it autonomously locates it for you.
This special item is very useful. When you input 'ghost' in the instance, it will mark the ghost's location, allowing players to precisely avoid danger and significantly increase survival rates.
However, Xiao Qiao doesn't often use this tool in instances; she frequently searches for miscellaneous items in the real world, like a missing sock, a gaming console that vanished shortly after being set down, and has even spied on Gu Mian's whereabouts a few times with it.
Later, the Big Data Search became a handy tool for the entire apartment, and everyone started borrowing it from Xiao Qiao to find misplaced items.
