His voice was not loud, but it startled Qin Yin. Perhaps it was because she was lost in thought. She lightly touched the screen of her mobile phone and the text message was sent just like that.
Qin Yin was startled but did not say anything. She just looked up at Shen Mingfeng and said, "There were no extra practice papers that day; everyone had just one, it was a perfect count."
"Yes, that's why I was puzzled," Shen Mingfeng discussed with Qin Yin, "If Miss Qin did indeed finish the test paper that day, then someone must have switched your test paper."
After saying this, he added, "There was a test paper with the name Qin Yin Han on it, but the 'Yin' character seems to have been striked off with a pen, so everyone unanimously decided that the test paper should belong to Qin Han."
