"Doesn't the Ghost Shadow only appear following players? What's the difference?" Wan Yunrong asked.
"Think about it carefully, the Ghost Shadow didn't appear on the players who turned into ghosts at the same time, which means there's only one of it, and it's movable. Since it can move, capturing the players is useless, the Ghost Shadow can run away at any time," Ge Pan said confidently, "So the ghost we need to capture for the mission is the Ghost Shadow, not the players acting as ghosts."
"That sounds really elusive," Wan Yunrong said. "The Ghost Shadow, how do we catch it?"
"How could a real ghost appear in a copy of the field?" Wu Xiaonan said. "That Ghost Shadow might be a special item, or it's an item or characteristic of a player hidden here. Don't forget the corpses on the third underground floor, maybe the Ghost Shadow is created by some hidden player."
"But where is he hiding?" Wan Yunrong said. "We've searched everywhere here."
