Ouyang stood up and said to Liu Lin, "Let's go right away and go to the mental hospital again!" ”

Liu Lin was silent and followed him out. Liu Lin drove, Ouyang Fan sat in the passenger seat, didn't say a word, just thought, like a big leader. Liu Lin looked at him sideways from time to time, really trying to tease him, but quickly dispelled the idea.

Entering the mental hospital, as soon as he entered the hall, Liu Lin found a figure and slowly walked towards the open ward. The figure was hunched over the waist, like an old man. But Liu Lin could see at a glance that it was Wang Han. He had obviously found out that Ouyang Fan and Liu Lin had come to the hospital. Why did he pretend to be an old man and walk, did he just do something bad?

Liu Lin dragged Ouyang Fan, and Ouyang Fan also saw it.

Liu Lin said in a low voice: "He is under the supervision of the police. ”

Ouyang Fan nodded.

If he did do something bad, the police would have known.

The two went directly to the monitoring room. The two young men in the monitoring room hurriedly gave up their seats. Ouyang Fan beckoned Liu Lin to sit down, brought up the video of Shen Wu receiving the items a few days ago, and watched it again.

He turned to the two young men: "Every time Shen Wu receives something, do you hold such a ceremony?" ”

"Yes."

"Think about it, has his ritual changed?"

"Didn't you?" The two young men said suspiciously.

"Have you destroyed all your previous footage?"

"It's not destroyed, it's all kept!"

Another young man immediately said: "No, we replaced the machine more than a month ago, because the previous machine was too old, it was always shut down, and it couldn't be repaired no matter how many times it was repaired." ”

"Where's the machine?"

"It was taken into the warehouse, and I heard from the section chief that it should be disposed of as an old thing. However, discs are available. According to Dr. Zuo's suggestion, in order to better study the patient's condition and prescribe the right medicine, the video was made into a CD and kept for at least five years. ”

Ouyang Fan stood up: "Thank you!" ”

He led the willow forest out. Liu Lin felt that Ouyang Fan might have found a problem. After taking a few steps, he suddenly remembered that the video he had in hand now was the video from two days before Ning Baolan was attacked. That is, on that day, Shen Wu received something and ran to the toilet to hold a ceremony. Isn't the previous ritual different from this one?

Ouyang Fan turned his head, immediately realized something, and said viciously: "You just follow me, don't talk much." If you leak a secret, you will be held responsible! ”

Liu Lin was stunned for a moment: Why did Ouyang Fan speak so fiercely? And, what is the responsibility, what is the responsibility?

Ouyang Fan ignored him at all and walked forward very impulsively.

Liu Lin smiled in his heart: This Ouyang Fan has a weird temper. It's cute, though.

Liu Lin stepped forward, next to him, and said funny: "Dr. Ouyang, I understand your words, and I promise to implement them resolutely and meticulously." ”

Ouyang Fan looked at him in surprise, didn't say a word, and walked forward again. Only then did Liu Lin realize that his mind was not on this, but all on the video. Liu Lin immediately regretted it, feeling that he was wrong to blame.

Liu Lin was sure that he had forgotten what he had just said.

The two found the head of the security section, who was a man in his forties who was slow and methodical. He opened the safe and looked through the CDs inside. He pulled out one of the CDs and said, "This is it." "I was about to hand it to Ouyang Fan, but I suddenly paused." No, no! He took the disc and looked at it repeatedly. The disc was in a very rigid plastic bag. "This bag has passed."

Ouyang Fan hurriedly asked, "How can you see it?" ”

But he didn't speak, but took the disc out of his bag and put it in the computer drive on his desk. The disc is empty!

The sweat of the security section chief immediately flowed, and he said in panic: "Something happened!" ”

Liu Lin hurriedly said, "It doesn't matter. Don't worry. He pulled Ouyang Fan, and Ouyang Fan immediately understood what he meant. The two of them walked out, and Ouyang Fan turned his head to the security section chief as he walked, "You wait a while, we will be back soon." You don't have to move this room, or CDs, or whatever. You just stay where you are, and that's it. ”

The chief of the security section nodded hurriedly. Liu Lin and Ouyang Fan got out of the hospital and came to the car, Ouyang Fan called Lu Zhijun and told him about the disc.

"You guys really can!" Lu Zhijun smiled, "Let me tell you, the disc was stolen by Wang Han." In order not to alarm him, we came to make a note of the package, and the disc has been exchanged back in our hands. We are working on the disc and there are no results at this time. Don't tell the chief of security the details, I'll call him. Wait, I'll make a copy of the CD. I'll send it to you. If you can help us find out what's in the disc, I'll treat you both to a big dinner. ”

Ouyang Fan was happy to eat: "This big meal, you have ordered!" ”

Ouyang Fan and Liu Lin continued to sit in the car. However, both of them wondered: what is the relationship between Wang Han and Shen Wu? Wang Han apparently knew about Shen Wu's murderous actions.

A small policeman came on a motorbike and gave them a CD. Ouyang Fan stuffed the disc into his laptop, operated for a while, and finally found the picture of the ritual that Shen Wu did in the toilet after receiving things last month. Liu Lin's eyes widened: the ritual that was done, although Shen Wu also raised his hands in a circle, he did not clench his hands and lay them across his chest, but after kowtowing, he walked out of the toilet with a drunken expression.

"Ha, ha!" Ouyang Fan seemed to breathe a sigh of relief and was very proud. "Liu Daxia," at this time, his mouth turned sweet. "You see, right? Shen Wu's attack on Ning Baolan was not a psychotic episode, but an animal intention. But as far as I can see, his animal intentions are only based on animal instincts, on the habits of life and action that he usually develops. In fact, it is only at the onset of the disease that the mentally ill person becomes delirious and delirious. After treatment, the five gods have already possessed the basic life skills and cognitive discernment abilities, of course, these abilities are only based on animal instincts. He must have received some kind of signal for action, and this signal can only come from what he has received. That is, the person who gave him something is one of the real criminals. The next step for us is to find out what kind of signals in these things will prompt God to kill people in the middle of the night. ”

Liu Lin couldn't help nodding, impressed Ouyang Fan from the bottom of his heart, and felt ashamed that he had wrongly blamed Ouyang Fan just now.

"Dr. Ouyang!" Liu Lin teased him, "Looking at your awesome appearance just now, I really want to beat you." However, now, I don't want to beat you, so I will temporarily prepare 20 strokes of the military stick and fight again if I am sick. ”

Ouyang Fan grinned: "Spare me, that's your blessing!" The truth will soon be revealed. Let's find the section chief immediately, bring all the other relevant CDs, and then go back. Feed! I said Liu Da martial arts master," Ouyang Fan said even more sweetly, "You still have a computer in this car, right?" ”

"Absolutely. Look, isn't that in the back seat! ”

"That's good! Back in my office, I'll give you a portion of the footage, and we'll search for them on two separate computers to see if we can find the sign that commands the five operations. Yes, it can only be a sign. Because the text is easy to leak the message. ”

"Alright, follow the doctor's command."

"Hee-hee!" Ouyang Fan punched Liu Lin and said, "Are you a little hungry?" Liu Lin, I want to eat shabu shabu, you won't be reluctant to give up those few taels of silver, right? ”

"Well said, well said! Let's go to the newly opened 'shabu-shabu' restaurant in the city, I heard that the decoration is very decent! ”

The two of them wanted to come to the relevant CD, so they went to the restaurant and ate so much that they shouted "hold on". Then, back to Ouyang Fan's office, he guarded a computer and searched for the information in the CD video.

The advantage of a closed ward in a psychiatric hospital is that there are surveillance cameras in almost every place, and the whole process of the intermediary delivering things is very clear. The two men cut out the images and focused on them. Ouyang Fan watched this month's video, while Liu Lin watched the video for the last two months.

It can be seen from the video that the nurses checked the things sent in from the outside very carefully, and the camera was also clear. Biscuits, sausages, cigarettes, etc., are all revealed one by one in front of the camera, but there is nothing abnormal in sight.

"Dr. Ouyang, what should I do if I put it inside something with the sign of the command?"

Ouyang Fan said: "If we really put it inside, we will be busy." ”

But the two of them still looked very carefully.

In the process of checking, in order to inspire his thoughts, Ouyang Fan re-called out the pictures of various civil gangs that he had collected before, and let Liu Lin see them one by one: "You see, these signs, armbands, badges, including the so-called symbols of the beggar gang, are all clearly marked. The black words of their team structure, such as the stack, cub, Buddha, etc., are all set in a set, and some words have been passed down for hundreds of years. As a member of the theft gang, Shen Wu has grown up in the gang since he was a child, and there will definitely be clear instructions for his actions. Don't let go of every picture, every line, especially what appears twice. ”

Sure enough, they found that both times a small boxy piece of yellow paper appeared for packaging food. It's just that the relationship between the pictures of the picture is that each lens looks at the yellow paper at a different angle. Liu Lin looked at the yellow paper on the front, and he could see that it was a piece of decorative paper, but it was wrapped in two rolls of bottles. When the nurse examined, she deliberately unfolded the yellow paper and faced the camera, so that she could see it clearly. The top half and the bottom half of the yellow paper each have two black curves, like simple art lines, and nothing else. And the piece of paper that Ouyang Fan looked at was also wrapped in two rolls of biscuits, but when the nurse examined it, she did not face the yellow paper facing the camera, but carried it diagonally and put it on the table, because there were other things on the table, so she covered the camera. Ouyang Fan had to process the yellow paper, first cutting it from other items, and then zooming in to barely see the details.

They finally found the problem.
