"Normal observation, statistics and probability, plus logical deduction," Qiao Ze explained succinctly, "It's nothing. I just wanted to make sure. You guys go ahead."
After speaking, Qiao Ze nodded at the two of them and then turned away, just in time to meet Su Mucheng who was coming over.
Then a few snippets of conversation drifted over on the breeze.
"Qiao, who are those people?"
"Don't know them."
"What? Then you..."
"Was just confirming something, but it's fine now. Are you going back to your dorm or...?"
"I think I'll go home."
"Alright."
...
"Lv, what's the situation?"
"What do you think? Weren't you bored? Is it interesting now?"
"No, but how did we all get recognized? We've only been following for a few days, right?"
"It's the thirteenth day."
"So, what do we do now?"
"Huh..." Lv Nan looked at the couple who were already more than thirty meters away, let out a sigh and said, "Follow them. We still have to complete the task."
