How Karl and the others were rescued, there are some details Gao Yang doesn't know, and the janitors wouldn't be generous enough to tell everything.
"How were you rescued, don't you know? You went through everything and remained conscious."
Gao Yang's casual remarks won't dismiss Karl, who seriously said, "I want to know how you did it. What I saw was just a small part, and there are too many unexplained points."
"Like what?"
"How did your people find us? Don't say it was a coincidence, and don't say you predicted where we would escape, because we ourselves didn't know where to go."
Gao smirked, saying, "When the police found you, I naturally knew where you were. It's that simple, the police were ahead, we were behind, waiting for a suitable moment to rescue you."
