"What do you mean?" asked the player who'd first fought Xu Huo, the one who played with metal cards. "There's only one way out for those of us trapped here?"
The old man glanced at him sidelong. "Didn't you hear what I just said? Seven. There are seven entrances and exits."
The player nodded. "I know, but only one door can open at a time. Doesn't that mean there's only one exit?"
"They can't all open in the same direction at the same time, but they can open in opposite directions," Xu Huo said. "Whenever someone is going out through one portal, someone could be coming in through any of the others. The doors might all open at once, or none of them might open."
The four players from the rescue team said nothing, but their expressions all said the same thing: Isn't that obvious?
"If several people go through one door, none of the doors might open. But if we split up, any of the seven doors could open," Xu Huo said. "I suspect there are so many doors in this space to make up for the lack of room. After all, the Dungeon covers at least eight cities and has four themes. Everything we've seen so far belongs to the Horror Theme. The Night Tour groups from the other themes might also be in this city, just in different districts and spaces. If so, the portals opening and closing could be a way of regulating how many people are inside."
"The ordinary people in the area we're in were sent away long ago by container items, but no newcomers have appeared here since. Your theory may be wrong," said the metal-card player.
"It could also be because there isn't much pressure in the Restricted Zone," Xu Huo said.
