Xiao Zhao hesitated for a moment and lowered his voice. "Actually, I don't think it was an accident. Brother Liu has been doing high-altitude homework for many years, and there have never been any accidents. Moreover, he's especially careful. Every time he uses the safety rope, he checks it once to ensure it does not suddenly break."
Shi Man pretended to be surprised and continued to ask, "Then do you have any other evidence to prove that this wasn't an accident?"
"I…" Xiao Zhao suddenly lowered his head and thought seriously for a while before making up his mind to tell the truth." Actually, I think I vaguely heard Brother Liu talking to someone downstairs, but I was too far away and didn't hear clearly."
Shi Man and Yi Zheng looked at each other and nodded. "Alright, I'll investigate the clues you just provided seriously. If you think of anything else, please contact us as soon as possible."
