Yu Shuai narrowed his eyes, "Doubting that I'm lying? Since we need to find the murderer among us, You Qiwen and Liu Zhengping seemed like they just came down from the third floor."
"We were looking for clues on the third floor," Liu Zhengping said immediately.
"Did you find anything?"
"We heard some noise and came right down immediately, without the chance to look further," You Qiwen explained.
Yu Shuai let out a cold laugh.
"Speaking of suspicion," Li Chao turned the light toward the twins, "one of you two was the last to arrive, right?"
Chen Tu and Chen Nan, with identical faces, made the same expression; the former said, "Don't try to turn things around, why don't you tell us what you did on the first floor after the power outage!"
