Changsheng: Peak at the Beginning

Chapter 1381: Hunting Crime + Fireworks 6

Zhai Lanxin led Shen Yi and Xu Qin all the way to the art classroom. When passing by a wall, Shen Yi specifically praised the desk panel hanging on the wall: "This form is really creative. Almost everyone who passes by will never forget the good old days of their youth."

There are all kinds of graffiti on the desks and boards. The brushstrokes may be immature or even disorganized, but the mood expressed is very accurate. Xu Qin can almost imagine through these desks and boards how their owners are seriously distracted in class.

Zhai Lanxin had heard a lot of praise, but the praise from her peers undoubtedly made her happier, and the reaction of Xu Qin, a representative of ordinary people, who showed that he understood the meaning of the poem, made her most proud.

Zhai Lanxin said modestly: "Some desks are scrapped every year. I found the graffiti on these desks very interesting, so I came up with the idea of ​​displaying them."

With the help of Zhai Lanxin, Xu Qin and Shen Yi obtained all the student works related to the skull, and Shen Yi took some time to determine that the skull must have been replaced in the sixth year of Ren Xiaoxuan's disappearance.

With this harvest, everyone followed the team back to the police station. Du Cheng and Jiang Feng had already collected biological samples from Ren Xiaoxuan's mother, and now they were just waiting for the results from the forensic doctor.

At Xu Qin's suggestion, Shen Yi stepped forward to share the results of their visit: "We have confirmed that the skull unearthed with the torso is a teaching aid donated by the medical school to the art classroom of No. 8 Middle School. The principal of No. 8 Middle School issued a relevant certificate, and we have also verified the certificate and the donation content to confirm that they are correct."

"In addition, we also got the replaced skull and sent it to the forensic doctor for identification. We have preliminarily determined that the two skulls were replaced about six years after Ren Xiaoxuan was confirmed missing."

Xu Qin added: "I have brought back the head of the art classroom, Teacher Zhai Lanxin, for questioning. Old Yan is watching."

Li Han also found out a lot of information: "According to the principal of No. 8 Middle School, the renovation of the stadium was proposed in January this year. He never disclosed any information before, and there was no delay due to sponsorship or other reasons. The reason why the construction started now is that the summer vacation is approaching, and the frequency of using the playground has been greatly reduced, which makes it easier for the workers to work."

Strictly speaking, up to now, no one has even found the crime scene, and the forensic department is currently trying to determine whether the playground is part of the crime scene.

However, Xu Qin felt that the playground would probably not be the first crime scene. At present, it seemed most likely that the deceased was Ren Xiaoxuan. Although Ren Xiaoxuan disappeared on the weekend, it was not easy to kill someone and bury the body. There were many people coming and going in the playground, and the land underneath would gradually become compacted, making it difficult to dig.

So Xu Qin asked Du Cheng: "Can you ask He Rongyue to help infer some of the deceased's activities before his death from the bones and the attachments on the clothes?"

Du Cheng couldn't help but laugh secretly, "You want He Rongyue to die suddenly from overwork."

Having said that, Du Cheng quickly became serious, "He Rongyue has already started. Thanks to your mother's generous donation, our forensic equipment has been updated. Otherwise, if it were someone else, He Rongyue would probably want to beat us to death."

DNA identification is the simplest job for forensic scientists. The questions raised by Xu Qin are the truly detailed and troublesome tasks. What's more, He Rongyue has other groups' work to deal with, and Du Cheng is pushing her too hard. The reason why He Rongyue didn't make a fuss was really because of the financial backer's face.

Seeing that no one had anything to say, Shen Yi took the initiative to step forward and said, "Why don't I try and see if I can restore the deceased's skull into a portrait?"

They had tried using AI to generate images before, but the results were hard to describe. Du Cheng didn't quite believe in Shen Yi's ability at first, but they really couldn't just sit here waiting for He Rongyue's DNA test report, so they had to agree.

Early the next morning, He Rongyue brought a lot of test reports: "The DNA test results show that the skeleton torso we dug out in the playground matches the skull we brought back from the art classroom."

"In addition, it has been confirmed that the deceased is Ren Xiaoxuan, a 15-year-old high school student who disappeared ten years ago."

"Also, the playground was not the scene where Ren Xiaoxuan was killed. We found some substances on her clothes that did not belong to the playground. Ren Xiaoxuan's clothes and the dirt on her bones came from at least two places."

Du Cheng exhaled a breath of frustration, looked at the results of a night's work brought by Shen Yi, and then looked at the obvious bruises under his eyes. He felt a little sorry, but now was not the time to care about these things. "Jiang Feng, come with me to Ren Xiaoxuan's house again to inform her mother of the news, and by the way, look for any clues in Ren Xiaoxuan's belongings."

Jiang Feng quickly agreed, and then Du Cheng looked at Xu Qin, "Xu Qin, do you have any ideas?"

Xu Qin said: "The clue we have about the skeleton now is that the place where the deceased was killed was not the playground. She was later moved to the playground and buried, and the skull was replaced four years ago. So can we guess that four years ago, the murderer heard some news that might lead to the discovery of Ren Xiaoxuan's body, so he hurriedly dug Ren Xiaoxuan out and buried her again in the playground?"

Li Han immediately made a guess: "The only information that could allow the murderer to dig up the deceased is probably news of demolition or something like that."

Xu Qin continued, "And it's very likely that he's around No. 8 Middle School. Of course, this is not certain. After all, I can't figure out what the murderer meant by replacing Ren Xiaoxuan's skull with the teaching aids."

Du Cheng will listen to Xu Qin's ideas, but he will not rely on Xu Qin's super intuition. After all, handling a case requires brainstorming. Various views and opinions should be put forward at the beginning, and then everyone will gradually eliminate them together to get the final result.

Du Cheng continued to assign tasks: "Li Han, you stay in the office to provide technical support. Xu Qin, you take Shen Yi to visit the school again to determine Ren Xiaoxuan's social relationships before his death."

Everyone responded and started to take action. He Rongyue had already gone back to continue her work after delivering the report. Even Li Han, who seemed to be staying in the office, would not have an easy task today.

Shen Yi got in the car, and Xu Qin took out a basket of snacks for him to hold. "You've been busy all night, so take advantage of this time to eat something to fill your stomach and take a nap. I'm a very steady driver."

Shen Yi's brain was still a little slow because of staying up late. He looked at the pile of snacks in his arms, and then looked at Xu Qin who was concentrating on driving. It took him a while to react, and a smile instantly appeared on his face: "I have stayed up late before, but what happened yesterday was nothing."
