Guo Mingyu felt that something was wrong, the scout he had sent out hadn't returned yet. Quickly, he ordered, "Send someone up to take a look."
The person who went up to check quickly returned and reported, "They're not there."
Song Zheng'an said, "It's like they vanished into thin air! That's impossible, I saw them before coming back."
"It's true."
"Something's not right, they might have been discovered and killed." Guo Mingyu guessed they might not be coming back.
"Discovered and attacked by us?" Xuan Wu asked.
Guo Mingyu deduced from the strange occurrence that they must have been discovered. There was no better explanation.
Xuan Wu spoke again, "If they have found us, would they have changed their pass route?"
Guan Yi replied, "It's possible. There could be other paths nearby we are not aware of."
Yet, Song Zheng'an argued, "We've checked all around. There are no other routes."
