Benjamin's words contained two pieces of information, tomorrow night and the meeting place.
From a functional standpoint, having Benjamin as an inside man was undoubtedly the best approach. Killing him and then blending into the Wika Village seemed too forced and difficult to implement.
Direct questioning was, of course, the best method at the moment, but Benjamin had stated that he could not be away for too long, so making choices was crucial.
Qian Cangyi planned to develop Benjamin as his helper, but first he had to rule out that Benjamin was just trying to deceive him.
Thus, he needed to set the time and place of their meeting himself.
Qian Cangyi spoke to Benjamin, saying,
"No, I won't meet you tomorrow; I will meet you in three days."
"I ask you, Benjamin, is the route you take to take out the trash fixed?"
Benjamin nodded.
Qian Cangyi continued,
"Good, I need you to keep it that way; I will find you in three days. Remember, don't mention this to anyone."
