Zhou Ning didn't speak and hastened out.
Just as he reached the half-flight of stairs to make a turn, the youngster opened the door, ran out in his slippers, and caught up to Zhou Ning to say urgently,
"I just remembered something else. When the senior girl was being controlled, it seemed like she tore at the man's ear, and he cursed, 'Damn, my ear's falling off!' After that he swore at the senior girl a few times and dragged her upstairs by her hair."
Zhou Ning nodded and patted the youngster on the shoulder.
"I've got it, thank you!"
They descended the stairs and walked towards the police car. Mr. Zhao looked back at the building and sighed softly.
"It's a shame no one was living on the fourth floor at the time. If someone had been there, perhaps they would have heard something."
Fang Mu shook his head.
