"The devil case, known as one of the five unsolved cases, is also called a serial suicide case!" Miao Ying took the information and introduced to everyone, "This case occurred between August 2002 and February of the following year. In about half a year, a total of 9 victims appeared in the northward moving area!

"These nine victims fell from an unmanned or abandoned building and died. Since there was no obvious sign of killing, most of them were classified as suicide! Even if two cases were filed for murder, they were ultimately unable to solve the case.

"Northern migration does not refer to a single city, but generally refers to Yingping, Guang'an, Changfeng and Beiqian areas. Due to the lack of Internet connection at that time, the way of death is similar to suicide, the backward investigation methods and the later SARS epidemic, this case did not attract the attention of the police at that time.

"On the contrary, a year later, when the police conducted a nationwide online investigation, they were discovered by a careful police officer and linked the cases of the nine victims.

"He found that the victims of these nine cases died very similarly, and the characteristics of the crime scene also have many common points. In addition, they all happened in a short period of time, so he determined that these nine cases must have some connection and are not small!

"So, he immediately drafted the documents and reported them step by step, and finally reported to the Criminal Department. The Criminal Department also attached great importance to it and immediately set up a special investigation team to go north to investigate. Captain Jin Zhenbang, who wrote the yellow notebook, was one of the investigators at that time!"

Speaking of this, Miao Ying took a breath and continued: "However, since it has been a year since the incident, the investigation of the special investigation team has not been smooth. The crime scene has changed a lot, and the victims have been cremated and buried, and no valuable clues can be found!

"In desperation, they had to focus on investigating the victims, but they regretfully found that the nine deceased not only had different genders, ages, and identities, but also had no connection with each other.

"Through the visit, I learned that all these nine people have no psychological problems such as depression. According to their families and friends, no one would believe that these people would choose to commit suicide!

"In addition, when the special investigation team visited the scene, they also found an important clue!" Miao Ying took out a picture from the folder and said to everyone, "When they investigated one of the crime scenes, they once found an eyewitness. The witness was an old man living near the crime scene. According to him, he had seen a ghost on the day of the crime!!!

"Here..." As he said that, Miao Ying raised the picture in his hand high, "This picture is the ghost drawn by the police based on the description of the witness!"

Everyone has learned about the general situation of the demon case before, so they are naturally not unfamiliar with this so-called "ghost". But the ghost in the picture has two curved horns, blood-red eyes, sharp ears like sharp knives, and fangs in the mouth are terrifying!

"The witness said," Miao Ying pointed to the picture and said, "That night, when he came out to relieve his hands, he suddenly saw a green light coming out of the vacant building opposite! In the green light, he suddenly saw this evil ghost, which scared him so much that he quickly got into the house, and almost got frightened!

"After drawing," Miao Ying pointed to the picture again and said, "Some experts recognized that this so-called 'ghost' is the demon in Western mythology and legend! As a result, the statement of the demon case has been passed down to this day!

"Because this case is full of mysterious and strange colors, it has been favored by the media for a long time and is widely publicized. There are even film and television crews who made movies based on this case, which is widely known.

"It is precisely because of these causes and conditions that the demon case has emerged from many major unsolved cases and has since become one of the five unsolved cases!" After saying that, Miao Ying laughed meaningfully, "Now, the Baishan Reservoir case has been settled. The headless female corpse case has also been solved by us! If this time, the demon case can be solved... that would be really amazing!"

"I hope..." Zeng Ke clasped his hands together and prayed, "Han Kuan is really related to the demon case? I hope I can find a breakthrough in him!"

"The year when the Demon Case happened," Wu Xiumin said, pointing to the information on the whiteboard, "It was the last year when Han Kuan went to school in Yaoming! Yaoming was in Tongjiang Province, and was thousands of miles away from moving north. At that time, Han Kuan was still in school. How did he get involved with the Demon Case?"

"I checked the information, unfortunately..." Zeng Ke shook his head and sighed, "The school where Han Kuan went to school back then has been completely ruined, and it has been yellow for many years, and basically no information can be found!"

"Then let's investigate Han Kuan's classmate record and class group, and work hard to find his classmates!" Miao Ying said, "No matter what, we have to figure out the details of Han Kuan when he was in school!"

"Yes!" Zeng Ke nodded and quickly did as Miao Ying told him.

Unexpectedly, at this moment, the office door suddenly opened, but Ran Tao walked in from outside with a computer case in his arms.

"Oh? Ran Tao, what are you doing with a computer?" Wu Xiumin asked in confusion.

"Do you ask me? Where do I know?" Ran Tao quickly hugged the case and came to Zhao Yu and said, "It was the team leader who asked me to do it!"

"Well...yes, yes!" At this moment, Zhao Yu was still carefully checking the information in the two boxes, not listening to Miao Ying and others, nor paying special attention to Ran Tao holding the computer. He just said without raising his head, "Put the computer there, let Zeng Ke check it carefully..."

"Oh, OK!" Ran Tao turned around and placed the computer on Zeng Ke's desk, "Here, Xiao Zeng, I'll leave it to you!"

"What... is this?" Zeng Ke was surprised, "What do you want me to check?"

"It's Zhang Jingru's office computer!" Ran Tao said, "I asked their manager. After Zhang Jingru was killed, they had never moved this computer. The team leader asked you to check it, just check it..."

"This..." Zeng Ke looked at Zhao Yu, not understanding what the purpose was?

"Nothing..." Zhao Yu looked through the information carefully and carefully and said to Zeng Ke, "Focus on checking Zhang Jingru's browser records, especially during the period before the incident! See which websites Zhang Jingru has been on..."

"Oh...oh..." Zeng Ke nodded, immediately installed the connection cable, and started to move.

"Zhao Yu...you..." Miao Ying looked at Zhao Yu's serious look and couldn't help asking, "Do you really think that new clues can be found in these two boxes?"

"Well...not sure, but I still have to look for it!" Zhao Yu said uncertain, but in fact it was the opposite. Because the location of his copy adventure today clearly indicated these two boxes. The system never aimlessly, so he firmly believed that he could find something from these two boxes...

"I think..." Miao Ying looked at Zhao Yu and said, "We may have to look for all the novels written by Han Kuan to check them out! As the saying goes, knowing yourself and your enemy will never be defeated, we should..."

Unexpectedly, before Miao Ying finished speaking, she suddenly saw Zhao Yu's eyes suddenly stopped on a piece of printing paper. He seemed to have noticed something from that piece of paper. He actually held the paper in front of his face and let the sunlight shine on it more comprehensively...

"Why...is there any problem?" Miao Ying was attracted by Zhao Yu's actions.

"This is someone's loan approval document, which was filed by Zhang Jingru. There was a lack of ink on the printing paper, which should be invalid!" Zhao Yu stared at the paper without blinking and said inexplicably.

"Hmm..." Miao Ying asked hurriedly, "What does this mean?"

"The document has a date, which was 0 days before Zhang Jingru's death! Also, this was originally a complete document, but from the page number, it was taken away on the page before this page!" Zhao Yu said again.

"Then..." Miao Ying guessed, "Do you think this person applying for a loan... has something wrong?"

"No! There is something wrong with the paper!" At this point, Zhao Yu finally raised his head, picked up a pencil from the table, and then said to everyone with bright eyes, "Everyone, the time to witness the miracle is coming!"

After saying that, he placed the pencil's tip obliquely on the piece of paper and quickly applied it.

As he applied, the pencil gradually covered part of the paper. As a result, under the reflection of the sun, an amazing pattern emerged from the smear!
