In order to show the importance attached to the special investigation team, the Beiqian Police Department has specially reserved one of the best case analysis rooms for them to use. This huge analysis room is ridiculously large, and it is no problem to accommodate 200 agents at a time.

"That's it!" After entering the house, Miao Ying immediately pointed to the big screen and said to Zhao Yu, "This receipt was found by us from Lang Xiangyang's relics, the receipt was opened by a clinic, and the clinic is downstairs from Lang Xiangyang's house!"

"We asked Lang Xiangyang's younger brother, and he said that in the first few days before Lang Xiangyang had encephalitis, he had already had some symptoms. Therefore, he should have gone to this clinic for a check-up, but because the symptoms were not obvious at that time, he was just given an infusion......

"Team leader, look!" Miao Ying pointed a red indicator at a certain place on the slip, "Pay attention to this payment time, it happens to be the day when the last case of the demon case happened. Since that day, there has been no similar case of the Demon Case!"

"Oh......" Zhao Yu nodded and said, "In other words, when the last case of the demon case happened, it was possible that Lang Xiangyang was receiving an infusion in the clinic?"

"It's hard to say, the time on the bill is 7 o'clock in the morning, when the clinic has just opened. And at that time, more than four hours had passed since the last demon case! Theoretically, Lang Xiangyang still had a chance to commit the crime!"

"However, I remember that the last case did not take place in the north, but in Guang'an......" Zhao Yu recalled, "Guang'an is 40 kilometers away from the north, and Lang Xiangyang went to the clinic early in the morning to see a doctor......

"The key is one point!" Miao Ying said again, "Lang Xiangyang can't drive! Every time he goes out to work, someone else takes him there!"

"Han Kuan!" Hearing this, Cui Lizhu couldn't help but interject, "It must be Han Kuan who went with him! Look, these two masters and apprentices may be a joint criminal! Let's take a good look, on that day, was it the hospital where Han Kuan sent Lang Xiangyang?"

"That makes sense, I'll go check it out! Ask the doctor who issued the bill!" Ran Tao nodded, and immediately turned around to make a call. Before leaving, he also deliberately gave Cui Lizhu a thumbs up, "Okay, these days, I haven't followed the boss in vain......"

"I asked Lang Xiangyang's younger brother," Miao Ying said, "but his younger brother can't remember clearly! It's a pity that Lang Xiangyang's lover has Alzheimer's disease and can't remember anything!"

"I think Xiao Cui is right," Zhao Yu said, "I also think that based on Lang Xiangyang's physical condition alone, he can't commit the crime alone, and Han Kuan may be his accomplice!"

"And that's not all...... There is no evidence to deny whether there are other murderers in this case!" Miao Ying nodded and said, "I'm really worried that the demon case was committed by a certain gang, and the murderer would be an organized and disciplined team......!"

"Team leader!" As he was talking, a man and a woman walked in from the door, and it was the man who greeted Zhao Yu, it was Zeng Ke. And the beauty next to Zeng Ke, Zhao Yu also recognizes it, it is Zhang Peipei, Gao Facai's beloved apprentice!

When he was in Quliang, Zhao Yu also had a quarrel with Zhang Peipei, so Zhang Peipei was a little jealous of Zhao Yu, and after walking into the office, he kept hiding behind Zeng Ke, not daring to look at Zhao Yu with his eyes.

"It's great that you're here! How are your legs?

Because Gao Facai's team had participated in the forensic work of the headless female corpse case, even Cui Lizhu knew this beautiful forensic doctor, and it can be said that there was no one alive.

"The equipment is on the way," Zhang Peipei said, "However, I just looked at the situation of the Northward Migration Forensics Section with Zeng Ke, and it fully meets our standards." So, as soon as my people come over, we'll re-inspect the scene and take samples again......"

Subsequently, Zhang Peipei said a lot of professional terms, and Zhao Yu didn't understand much, but out of politeness, he nodded frequently.

"Team leader!" After Zhang Peipei finished speaking, Miao Ying began to introduce their current investigation to Zhao Yu, "Because the time is too long, we can't restore the trajectory of Lang Xiangyang and Han Kuan 10 years ago. However, according to Lang Xiangyang's younger brother, at the beginning, although Lang and Han had only worked for half a year, they had been to a lot of places.

"Their company is mainly engaged in teaching equipment and equipment, such as special classrooms, music blackboards, projectors, voice equipment and so on...... Although I am also responsible for some of the maintenance work, most of them are new. So, although it has only been half a year, they have been to too many places, and they rarely repeat each other.

In his impression, in addition to the northward migration area, it even includes Tongjiang and Baiyun and other places, and the scope is very large!

"What's worse is that due to the company's repeated restructuring, those documents and bills from 10 years ago are almost impossible to find, so there is no way to know where Lang Xiangyang and Han Kuan went at the beginning!"

Listening to Miao Ying's report, Zhao Yu nodded silently and memorized these details in his mind one by one.

"In addition, through the cooperation of the northward relocation police, except for the old lady in her 60s, we have basically investigated that most of the victims in the northward migration demon case are suspected of bullying others before their deaths!" Miao Ying said again, "However, except for the campus bully Lei Ting, who can sit down, everyone else is limited to suspicion!"

"Old lady?" Zhao Yu repeated.

"The old lady and her children have not been in contact with each other for many years," Miao Ying said, "but I heard from the neighbors that the old lady has a very strange temper and is not easy to get along with." But...... We can't think of any bullying incident that a man in his 60s can do......"

"Will it ...... What if this old lady accidentally saw the murderer?" Cui Lizhu interjected suspiciously, "Someone killed her?"

"All in all, the demon case is short in time and has a large number of crimes, which is very different from ordinary serial murder cases!" Miao Ying ignored Cui Lizhu and continued, "It's easy to commit a crime, but it's difficult to find a target! In such a short period of time, there is not much time left for the murderer to find the target! We have made a lot of guesses, but we just can't guess, how can the murderer find the target so quickly?"

Oh, yes!

Before, Zhao Yu had also had such doubts. Take the headless female corpse case as an example, even if Li Fei was back then, he only found a suitable target every year or so. But how could the murderer of the demon case kill nine people in a row within half a year? Can he ensure that all nine of them have bullied others?

There's no way they're going to ask questions, right? Everywhere they go, they ask, hey, big brother and sister, where are the bullies around here? I'm going to get rid of him?

Well...... Because of this, Miao Ying is worried that there will be a mysterious organization behind the demon case, right!? Only if you act collectively, this case will be more reasonable!

But...... Is there really a demonic organization?

"Boss, Sister Miao, I have found the doctor in the clinic who treated Lang Xiangyang back then!" Ran Tao said from a distance, "Because Lang Xiangyang died in the hospital later, the doctor remembers clearly, at the beginning, it was Lang Xiangyang's lover who supported him! The doctor saw that Lang Xiangyang's condition was not very good, and he once suggested that he go to the big hospital for a careful examination."

"However, Lang Xiangyang still had important work to do that day, so he only let him simply infuse some liquid, and then left! Who knows, later, in less than a week, he heard the news of Lang Xiangyang's unfortunate death!"

"If that's the case, at least the last demon case shouldn't have anything to do with Lang Xiangyang, right?" Miao Ying guessed.

Just as Miao Ying was speaking, a faint morning light had poured out of the sky, which happened to shine on Miao Ying's beautiful face.

The sun is out!

Zhao Yu suddenly remembered today's "Qiangen" hexagram!

If you want to solve the case, you have to hurry!

Thinking of this, Zhao Yu hurriedly snapped his fingers and said to Miao Ying: "By the way, I came all the way here, so let me see that demon suit first!"
