"You said Mr. Chen took that photo of me?" Ye Yu was puzzled, "I said at the time, I didn't have any face-to-face contact with him that day, and the surveillance video can prove my innocence." ”

"There are some things that you don't have to do yourself. For example, let Chen Yan also experience a "fantasy" like the one you experienced earlier. Lou Yue said, "As long as you find a way to make him fall asleep temporarily and put it in a relatively closed environment, it is easy to control it through the controller, and the car where Chen Yan's body was found is an excellent implementation environment." ”

The cause of Chen Yan's death was instantaneous shock caused by external stimuli, which was simply scared to death. Thinking of his previous personal experience, Ye Yu believes that this kind of "illusion" can indeed bring a certain amount of stimulation, but it is a bit far-fetched to the point of shock.

"If it's just the stimulation of the virtual reality environment, the possibility of directly shocking people to death is actually very small." Before Ye Yu could ask, Lou Yue opened his mouth directly, and at the same time called up a screen from the bracelet, which seemed to be a report. "But for a brain that is severely overloaded in the short term, this stimulation is sufficient."

"This is the test report of Chen Yan's brain, which shows that his brain has been intensively overloaded in recent times and has reached the critical point of collapse." Sister Mu on the side explained.

"This ...... What does it mean? I don't understand. ”

"Hehe~ Since you know the particularity of our bureau, then you should think that ordinary criminal cases will not find us. The reason why we intervened was naturally related to the Blood Keystone. Sister Mu leaned over, sat lightly on the armrest next to Ye Yu, put her hand on the back of the chair, and said to Ye Yu with a smile.

The faint smell of perfume on Sister Mu's body made Ye Yu feel a little uneasy, and he couldn't help but speed up, and hurriedly moved his body to the side with a red face.

"It's a sequelae of overuse of the Bloodstone." Lou Yue said a word. "There is a price to pay for the use of the Blood Keystone, it greatly enhances the human brain waves, but also puts a great load on the brain, if used continuously in a short period of time, then the brain will become extremely fragile, and the timely stimulation will cause it to collapse."

"In other words, Chen Yan's death was carefully planned, and the murderer is likely to be related to the Blood Keystone?"

"Actually, we started paying attention to Chen Yan a few months ago. As you may know, since February this year, in just three months, H Group has completed several annexation projects in a row, and the process has been extremely smooth. We received information that Chen Yan had mastered the secrets of several important people on the annexed side in the process, so that he could successfully coerce the other party to complete the annexation. And this information, without exception, was obtained quickly after Chen Yan met with these figures. Sister Mu's laughing expression gradually faded, and her tone became serious.

"It's like...... He read the other person's memories directly during the meeting? ”

"At least that's what the higher-ups are suspicious of, and because it may have something to do with the Blood Keystone, they asked us to secretly investigate him. And we did find some clues in our investigation. Lou Yue called up a few photos on the virtual screen, which seemed to be Chen Yan's profile photos.

"The first three are photos of Chen Yan during last year's cooperation activities, while the last few are photos of Chen Yan's information at several annexation meetings this year. Did you find anything noteworthy about this? “

Ye Yu looked at the photos carefully, and felt that each one seemed to be about the same, nothing more than some actions such as shaking hands and taking photos, Chen Yan's expression was natural, the background of the photo was relatively monotonous, there was nothing special about it, and it seemed that he was wearing it...... Hey? Wait a minute......

"Can you enlarge Chen Yan's hand in the next few photos?" Ye Yu noticed something, "The ring on his hand seems to be ......"

"Although you are a rookie reporter, your observation skills are not bad." A hint of appreciation flashed in Lou Yue's eyes, and then he enlarged a close-up of Chen Yan's hand.

In those photos of the annexation meeting, Chen Yan seems to have a ruby ring on the index finger of his right hand, although the photos cannot clearly show its luster, but in terms of color, it is somewhat similar to the blood keystone.

"Have you investigated that ring?" Ye Yu looked at Lou Yue.

"That ring was obtained by Chen Yan through some channel at the end of last year. We have not found any transaction records regarding the ring, presumably purchased on the black market. However, since this is Chen Yan's personal belongings, if I directly request an investigation without evidence, it will not comply with the regulations, and I am afraid of startling the snake, so I originally wanted to take the opportunity of Wu Xuebing's disappearance to meet him directly, but unfortunately it was a step too late. ”

"He had an accident on the eve of his meeting with you...... So, did you find the ring after he died? ”

"It was taken." Lou Yue's always calm expression cast a slight shadow, "It was the night of Chen Yan's accident." ”

A surveillance video appeared on the virtual screen. This is the picture of Chen Yan walking out of the north gate of the main building at that time, and you can see that he is still wearing the ring on his hand. However, at the scene where the body was found, the ring was gone. We carefully searched the site and the entire park, but found no trace of the ring. ”

"In other words, someone secretly took the ring that looked like a blood keystone at the scene, and that person is likely to be the murderer?"

"Yes." Lou Yue raised her eyes, "However, during the execution of the murderer's plan, there were some unexpected situations, resulting in the tail being exposed. ”

"Unforeseen?"

"It's Chen Yan's abnormal behavior." Lou Yue adjusted the bracelet, and the virtual screen showed a three-dimensional image of the headquarters of Group H. "Let's recreate the scene at that time. At 9:30, Chen Yan set off from the office, and appeared at the north gate of the hall on the first floor of the main building five minutes later. ”

The roadmap of Chen Yan's actions was displayed on the screen, and the time was marked on the side, which seemed to be clear at a glance.

"The road between the main building and the annex building is not monitored, and we don't know what happened to Chen Yan on this section, but according to the information we have later, we can confirm three facts:

First, after Chen Yan left the north gate of the main building, the surveillance video of the annex building and the underground garage did not capture Chen Yan entering;

Secondly, Chen Yan took a photo near the South Gate at 9:45 and checked it repeatedly;

In the end, Chen Yan's body was found in his own car in the underground garage of the annex building. ”

"Wait, there is an obvious contradiction based on the facts you have listed. Since the surveillance video of the annex building and the underground garage did not capture the footage of Chen Yan entering that day, why did Chen Yan's body appear in the car in the underground garage out of thin air? This doesn't make sense! ”

"Everything that seems irrational can be explained by reason. What we know is that the surveillance cameras did not capture it, but it does not mean that Chen Yan did not enter. Lou Yue moved the bracelet again, and the plate pictures of the annex building and the underground garage on the screen were enlarged, and the three-dimensional building was perspective, and several red dots appeared inside. These are the locations where surveillance cameras are deployed in the annex building and in the underground garage. It is mainly distributed in the main passages such as doorways, halls, and elevators, and is not very dense. Theoretically, as long as you are familiar with the deployment of the cameras, it is possible to successfully evade surveillance and enter the garage. ”

"And this area is Chen Yan's dedicated parking space." A spot in the frame is highlighted, and it can be seen that there is no red dot near this area. "There are no cameras installed near Chen Yan's dedicated parking space, and for whatever reason, we can't tell how Chen Yan got into the car through the surveillance."

"Since there is no surveillance near the parking space, there should always be one on the way to the parking space, right?"

"There are two routes to Chen Yan's parking space. The first is to go down to the underground garage through the elevator in the lobby of the annex building, and the second is to enter the garage through the fire staircase of the annex building, both of which are equipped with surveillance cameras. If you take the elevator, you will definitely be caught by the camera inside the elevator; In this way, the only way for Chen Yan to enter the garage is the fire staircase. “

"But there are also monitoring probes on the fire stairs, and if you go down this route, you may be photographed, unless you ......"

"Unless Chen Yan deliberately dodged the camera." Lou Yue gave the answer.
