Chen Xuan suddenly understood.
No wonder they had not dared send anyone down to the fifth level to repair the water purifier.
Did that mean every shelter built around a subway station was under threat from a Large Nano-Lifeform?
"What if it climbs up here?" Xiao Jiu asked fearfully.
"Hahaha—don't worry about that. It only moves along the tracks. It can't reach the floors above them," Mingzi reassured her. "We've been trying other ways to reach the fifth level without using the tracks, like digging a tunnel."
Ryan chimed in. "As long as we leave it alone, it might as well not exist. Sha River Station even has a game called Guess the Train. You lie by the stairs between the third and fourth levels, where you can see the Ghost Subway up close, then bet on when it'll appear and who its passengers will be. The closest guess earns Credit Points."
"Passengers?" Chen Xuan frowned. "Who would dare ride that thing?"
Zhuang Yu, Ryan, and Mingzi exchanged glances.
"You've never seen someone killed by a Large Nano-Lifeform?" Ryan finally said. "Unlike the smaller ones, they keep some of their victims as food reserves, hanging them from their bodies like cured meat. That's what we mean by passengers."
Chen Xuan immediately remembered the corpses dangling from that colossal leg. They had swayed in the sandstorm like insect pupae.
"Ugh—" Xiao Jiu looked sick.
"Ahem. Personally, I find that game disgusting," Ryan hastily added after clearing his throat. "It's terribly disrespectful to the dead. The leader ought to ban it outright!"
The other two nodded repeatedly.
But Chen Xuan could tell Zhuang Yu was the only one who truly objected to it.
"Can you tell us about the Five Overlords? What else is there besides the Ghost Subway?" Jiang Siqi asked
