Listening to the voice in Zuo Ling's ears, he asked quietly: "Is there a light on in the music classroom where Cheng Yiyi and they are?" ”

"Nope." Sun Qian replied quickly.

There is no need for Zuo Ling to say this, Xu Jingnan can hear the question, he raised his eyebrows, and asked quite strangely: "Then how can you see that Cheng Yiyi is pushing down is Jiang Chenxing who is in a coma?" So how can Hei see clearly, why didn't Jiang Chenxing jump down by himself. ”

Sun Qian was stunned for a moment, and subconsciously said, "There is moonlight......

On the other end of the phone, Zuo Ling, who heard this, suddenly laughed.

"You asked her, did there be two moons that day, and how did the two classrooms with opposite windows and a corridor in the middle make the moonlight and rain evenly wet."

If there is moonlight shining in from the window of the music classroom where Cheng Yiyi and Jiang Chenxing are located, then this moonlight is facing away from the window of Sun Qian's dance studio.

If there is moonlight shining in from the window of Sun Qian's dance studio, then in the same way, the music classroom where Cheng Yiyi and Jiang Chenxing are located is pitch black.

You can know that no one turned on the lights in the classroom that day, otherwise the security guards on patrol would have gone upstairs as soon as possible. What is known is that Jiang Chenxing was discovered by the patrolling security guards an hour after jumping to his death. In other words, this hour is enough time for the murderer to escape.

But if the lights were on, the security guards would have rushed over as soon as possible, and they would not have found Jiang Chenxing's body so late, and maybe they could still block the murderer.

Therefore, Sun Qian's words are very flawed.

"I ...... I think I'm mistaken, I think the lights are on, and the lights are on in their classrooms. ”

"Ask again what time the lights are on."

"What time do you see their lights on?"

"I ...... I don't remember very clearly, it should be that they turned on the lights as soon as they entered, and then I saw Cheng Yiyi stunned Jiang Chenxing, and then Jiang Chenxing didn't move, and Cheng Yiyi turned off the lights again, and then pushed Jiang Chenxing down. ”

"And how long do you think the process will take?"

Xu Jingnan asked obediently. Sun Qian thought for a while and said for ten minutes.

Zuo Ling raised her eyebrows, "She said that she saw Cheng Yiyi and Jiang Chenxing go in at ten o'clock, and turned off the lights after ten minutes, and that time was around ten o'clock." You asked her if she knew that every day at 10 p.m., all teaching buildings would cut off the power supply on time. ”

"Do you know that after our investigation, every night in Beiying University, except for the dormitory, which will be half an hour late, the teaching building is ready to cut off the power at ten o'clock."

Sun Qian: "......"

Seeing that she was silent, Xu Jingnan frowned and put on a serious look, "I'll ask you again now, have you ever seen Cheng Yiyi push the unconscious Jiang Chenxing down with your own eyes." ”

"I saw it! It's probably been a year, I really can't remember too many details, maybe they didn't turn on the lights, and the flashlight on their mobile phones couldn't be said, but there was light anyway. Sun Qian hurriedly explained.

"You even remember the time clearly, you can even remember clearly which window Jiang Chenxing and Cheng Yiyi were standing in, and now you have been hesitating to say a question of whether to turn on the lights or not."

"Maybe I'm just misremembering. Anyway, it's either moonshine or someone turned on a mobile phone flashlight. ”

Zuo Ling was already a little impatient, snorted, and said:

"Tell her that it was before the National Day, it was cloudy, and there was no moon."

Because it is close to the National Day, it is still easy to go back and check the weather that day.
