The others did not speak, and the scene fell silent for a moment.

When Xia Mu arrived at the classroom, he found a figure that should not have appeared here - Cang Leng.

Seeing Xia Mu appear, Cang Leng's eyes lit up, he forgot his position as a cold goddess, and waved his hand.

"Cang Leng, why are you here? No wonder I didn't see you when I went back to the dorm just now. Xia Mu was a little surprised.

Because of their acquaintance, Xia Mu simply sat next to Cang Leng.

Cang Leng took out a breakfast directly from the drawer, "Eat, I bought it for you." ”

Xia Mu then remembered that the original owner actually didn't have the habit of eating breakfast on weekdays, and Cang Leng was used to taking care of her.

Xia Mu shook his head a little apologetically, "I'm sorry, I didn't know you would help me prepare, but I've already eaten it." ”

Cang Leng pursed his lips, "It's okay, it's also to blame me for not taking much care of you on weekdays." ”

"If I treat you a little better in normal times, I'm afraid your health won't be so bad."

Xia Mu emphasized again, "You guys have taken care of me enough on weekdays, you really don't have to blame yourself." ”

Soon she started to take classes, because Xia Mu had fallen behind too many classes, so she was very serious.

Looking at Xia Mu like this, Cang Leng kept wanting to speak and stopped.

As soon as the bell rang for the end of class, Xia Mu saw a familiar figure - Ming Cheng.

Xia Mu's eyes widened, and he quickly lowered his head and sent a WeChat message to Mingcheng.

"Why are you here?" Xia Mu was extremely shocked by Mingcheng's appearance.

"The previous case has produced some new clues, and I have to go this way."

"Does it have anything to do with the cold?" Xia Mu's first reaction was this.

In fact, if you look at the conditions alone, Cang Leng is 1.7 meters tall, thin, and female.

It bears a strange resemblance to the murderer from five years ago.

Xia Mu couldn't help but glance at Cang Leng with his afterglow, and quickly retracted his afterglow.

Anyway, this is still a school, and Mingcheng can't help but leave some leeway for Cang Leng.

After all, Cang Leng is still an ordinary student, and if it turns out that everything is a misunderstanding, she still has to return to normal life.

But who doesn't know that the school is the fastest place to spread messages, so Mingcheng has to be cautious.

When the entire classroom was finished, Mingcheng walked in with people.

And Xia Mu walked behind Ming Cheng by inertia.

"Miss Cang Leng, you are related to a murder case five years ago, please come with us."

"It's not necessary for you to say it, unless you want to say it, but everything you say will be taken as evidence in court."

Cang Leng's eyes were very calm, but he looked at Xia Mu with some disbelief, "Did you bring them here?" ”

"Tell me honestly, is that you?"

Xia Mu's eyes were lowered and he didn't speak for a long time.

"Okay, even if I misread you, Xia Mu, I didn't expect you to be this kind of person." Cang Leng left two sentences coldly, and was taken away.

Xia Mu buried his head in his arms, his mind disordered.

Ming Cheng stopped talking and rubbed Xia Mu's head.

"Actually, it's not sure if she's it now, but Cang Leng has to go back and be investigated."

In fact, Ming Cheng did not connect the murderer with Xia Mu's classmates at the beginning, until another conversation with Uncle Wang.

Coming out of the house this morning, Ming Cheng took Chi Feng to Uncle Wang's house along the way.

"Uncle Wang, you still have to think about it again."

Uncle Wang, as a person who has been indirectly in contact with the murderer, has the most right to speak.

"Mingcheng, Uncle Wang wants to catch the murderer more than you, but I haven't found a clue after thinking about it countless times."

"I even listened to that phone call a thousand times, but nothing came of it."

"I even dream of being the girl's voice every day, but I don't get anything out of it."

"Recording?" Ming Cheng said.

"yes, that's the last conversation I had with my daughter." Uncle Wang didn't know why Mingcheng suddenly mentioned that recording, and he was a little puzzled.

"Would you mind telling me about it?"

Although Mingcheng knew that his request was a bit excessive, for the sake of the truth of the case, he had to open Uncle Wang's constantly healing wounds again.

Uncle Wang was silent, staring at Ming Cheng and not speaking for a long time.

Mingcheng didn't bother him, just looked at it like that, serious and serious.

"That's it," Uncle Wang sighed, "as long as there is a glimmer of hope to catch that murderer, I will admit it." ”

Uncle Wang hobbled and took out a worn-out mobile phone, full of nostalgia.

"This is still a gift that Yuanyuan bought me with her first salary after going to college to work part-time, and I am reluctant to throw it away all these years."

"Nowadays, it's more like a time machine that lets me know I'm not alone."

"Now, I'll give it to you."

Uncle Wang solemnly put the thing in Mingcheng's hand, full of reluctance.

"Uncle Wang, you can rest assured, I guarantee that there will be no damage to the contents inside."

Mingcheng skillfully picked up his mobile phone and clicked on the recording clip that Uncle Wang had listened to for five years.

"Hey, Dad, why did you answer the phone, I've called many times. I thought something had happened to you, it scared me to death! ”

"Hehe, your dad and I are old and strong, you little girl is too underestimated by me."

"You, are you smoking again, I listen to your voice is a little hoarse, be careful I tell my mother!"

"You little girl, you threaten me with your mother again. Tell me what's the matter, or I'll hang up? ”

"Don't, Dad, that, I made an appointment with my friend to have hot pot together in the evening, Mom, you can help me talk about it."

"I knew you had something to ask me for, but remember to come back early."

"Okay, Dad, I love you, don't say it, I'm leaving."

The phone stopped abruptly, and there was silence again.

"Chi Feng, try if you can reduce the voice of your voice and increase the background sound."

Mingcheng always felt that he had heard some special timbre just now, but he was not sure.

Although Chi Feng is in the field, he has always been an expert in sound before.

For distinguishing background noise, Chi Feng is really good at it.

"Don't worry, I'll leave this matter to me, the slowest hour, you wait for me."

It's not easy to use professionalism, and Chi Feng is a little excited.

Grab the laptop you have with you and get into the groove quickly.

Uncle Wang and Mingcheng have been standing next to each other, constantly smoking, and the cigarette butts are scattered all over the ground.

"How much longer?" Mingcheng took a sharp puff of his cigarette and stomped on the cigarette butt.

"Head, wait."

"Because this recording has been going on for a long time, I use the recorder that comes with the mobile phone, and the sound quality is not too high, and there is too much noise."

"I'm trying to separate the background sound from the vocals, but I'm not sure how it works."

Chi Feng didn't have much confidence in this recording, but he trusted Mingcheng's instincts extremely much.

On the issue of the case, Mingcheng has never been at fault.
