today's island

I don't know whether it's because of guilt about the murder case or because he is afraid of Cheng Mo's identity. Director Jiang came out to greet them in person, and shook hands with them as if they were old friends they hadn't seen for many years. : "This is Shen Li, my secretary."

Although Secretary Shen was young, he behaved gracefully and without shyness at all. He shook hands with them warmly but politely, and in turn marveled at their youth and promise.

It took only 3 minutes to exchange pleasantries. Lu Yuanzhe finally took the initiative and praised the institute. This long reception finally entered the second stage - Director Jiang's self-promotion.

Leading the secretary to sing along, Director Jiang vigorously introduced the achievements of their institute in recent years, and the words were hype.

Lu Yuanzhe didn't understand, but he understood. The frequent glances at Cheng Mo were for Cheng Mo's father.

Cheng Mo seemed to have done some homework on their project. Whether it was biomedicine or ecology, he could more or less pick up the conversation.

Seeing that he was so interested and had an inexperienced face, Director Jiang felt relieved, and began to float, blowing so loudly that Lu Yuanzhe seemed to be aware of some flaws.

Cheng Mo really cooperated, with a smile on his face and sincere eyes, exactly the same as when he first joined the task force.

Lu Yuanzhe sighed in his heart. Except for him, it seemed that no one could see through the disguise of Cheng Mo, a five-good student.

Although it is a fairly advanced research institute in Daocheng, the buildings are very simple and are all standard cuboids without any artistic design.It may be that the experimental accident will spread to the surrounding area. The distance between each building is several hundred meters, and there are some bushes and trees in the middle as isolation belts.

Along the way, Lu Yuanzhe observed all the way, a three-story dormitory building, according to director Jiang's introduction, when there are many people, more than half of it can be occupied, but these days are relatively deserted; an experimental building with the largest area One basement floor, four floors above ground, all the experiments that can be done indoors are here; a five-storey office building is used for office and reception; finally there are some auxiliary buildings, some experiments are not suitable for completing in the building , also built a separate small room.

It wasn't until they were introduced into the main office building of the research institute, and after introducing the lobby and various departments, that Cheng Mo asked with that harmless face, "Can you lead us to see the researcher who happened now?"

"Before eating?" The topic turned a bit hard, Director Jiang was taken aback for a moment, "Would you like to take a rest first?"

"It's okay, the delay won't be long, maybe it's not a big deal?" Cheng Mo laughed.

Director Jiang loves to hear these words: "Okay, then I will ask Xiao Shen to put your luggage there first, and I will take you to have a look first."

Lu Yuanzhe sighed in his heart, okay, I'm hooked.

Leaving the simple and elegant office building, they walked towards the slightly shorter laboratory building.Affected by the typhoon, it was getting late, the sky was getting dark, and the street lights along the way were turned on. If there is a real power outage, it may not be easy to go.

"It's really a simple situation." Director Jiang introduced them while leading them over, "You know, sometimes samples are taken in the middle of the night for experiments, and He Zhigang is the employee who stayed overtime yesterday."

Last night, the deceased He Zhigang worked overtime in the 403 chemical laboratory in the middle of the night in order to collect samples.He did a microbiological gas production experiment that night, which is non-toxic and harmless in theory, just take a sample and inject it into the instrument, so he didn't arrange other people to work overtime with him.

He didn't come out for breakfast, but the lab was fine, and no one cared.Until ten o'clock in the morning, someone came to him, but no one responded to his calls, so he had to ask the person in charge of logistics to ask for the key card.

The door was opened by swiping the card, but the anti-theft chain was hung, and it was still impossible to get in, and no one could wake up. Finally, they only cut the anti-theft chain and entered the house, only to find that he was not breathing.

"He lived alone and couldn't find any injuries, so he could only think about sudden death." Director Jiang concluded.

"What time is the experiment?" Cheng Mo routinely took out his notebook to record.

Director Jiang thought for a while and replied, "Ten past four in the morning."

"So accurate?" Lu Yuanzhe asked.

"It must be very accurate." Director Jiang nodded, "The laboratory has to fill in and sign the records, and someone checks them every week. We just read the records left by Xiao He last night."

"Then what about the instrument he used?" Cheng Mo asked, "Is it dangerous?"

"It's just an ordinary gas chromatograph." Director Jiang introduced.

"Gas chromatography?" Lu Yuanzhe muttered with a frown. It's really difficult for liberal arts students to understand. No matter how you think about it, it's all about the weather.

"Uh... that's it." Director Jiang took out his mobile phone, searched for a long time, and flipped through several pages. Finally, he found a complete picture and handed it to Lu Yuanzhe. "It's this cube. The specific principle may need to be given by the staff. You introduced it, but there is absolutely no gas threat."

"Is there no monitoring in your laboratory?" Lu Yuanzhe asked, "Did he go and return on time?"

"No, everyone doesn't like being stared at, plus the building is clocked in and out, and it's on an island, so there's really no need to guard against theft in the laboratory building." Director Jiang sighed, "As you know, there are many experiments to do. Waiting time, everyone has to play with mobile phones and the like, and don’t want to be watched.”

There is no surveillance in such a large research institute. Lu Yuanzhe immediately glanced at director Jiang, but he didn't read the guilty and lying expression on his face.

"However, he clocked in and out of the laboratory building and laboratory normally, and there are clock-in records." Director Jiang didn't notice his gaze, and added calmly, "He went at two o'clock, left around 04:30, and the experimental samples also Tested normally."

"Go at two o'clock?" Lu Yuanzhe was also a little confused about this time.

"The instrument has to be turned on in advance to test samples." Director Jiang explained, "It's normal to go at this time."

"Then who was the first person to find him?" Lu Yuanzhe continued to ask.

"It's Lao Cao." Director Jiang replied, "It's the person who collected data for him this morning. People often arrange experiments like this. One person will work overtime in the middle of the night, and the instrument will run automatically. In the morning, another person will record data and shut down. "

Chatting about the issues related to the case, they walked to the laboratory building in a short while. Compared with the ordinary office building, this place has a more technological sense. In addition to the gate, each laboratory also needs to swipe the card, and only relevant personnel and management can enter. .

The corpses are parked in the innermost warehouse on the first floor. This floor is mainly used to receive outsiders and pile up useless experimental products. Everyone will not come near this place in the middle of the night. Putting it here will least disturb other people's work.

Fortunately, it is a biochemical research institute, so it was able to find a freezer to bury the body. Otherwise, it would be difficult to digest before eating.

He Zhi was 24 years old just now. He was slightly fat but still healthy. It really didn't look like he would be in a state of sudden death.

They asked Director Jiang to borrow the laboratory bench in the room, they closed the door, and quietly dialed Ling Xi's phone number.

Lu Yuanzhe's experience in autopsy is limited to the verbal reports of elites in the forensic department, as well as some basic studies during school, there is really no way to make an assertion on this kind of corpse with no trace of scars.

"I've really never done a remote autopsy." Ling Xi complained on the other end of the phone, "Forget about the video, it's still audio and pictures."

"The signal is limited, so I can't broadcast live. What can I do?" Lu Yuanzhe replied helplessly, the typhoon is coming, it is really not a good time to talk.

There was no ferocious expression on the face of the deceased, and no bruises of struggle were left. The corpse spots were obvious. Lu Yuanzhe and Cheng Mo checked the body surface of the deceased thoroughly, and found no conspicuous pinholes.

After taking a lot of photos of Ling Xi, Ling Xi's first guess was suffocation: "Although I'm not 100% sure, his symptoms are very similar to non-mechanical suffocation."

"What symptoms?" Lu Yuanzhe didn't notice suffocation at all.

Ling Xi paused for a while, and gave an example: "For example, gas poisoning such as carbon monoxide, the body surface of the deceased will have no scars, and it may not necessarily show obvious symptoms of suffocation."

"Then how do I find out what the reason is?" Lu Yuanzhe asked.

"Dissect, slice." Ling Xi replied.

"Of course it can't be done." Lu Yuanzhe shrugged.

"I can't find any scars on the surface. The most likely thing is poisoning. Many common highly toxic chemicals will leave certain traces on the body surface. The symptoms of chemicals that cause suffocation are less severe." Ling Xi explained, suddenly After a pause, he added, "Of course, it is not ruled out that it was simply sudden death due to illness."

"What about other homicides?" Lu Yuanzhe asked.

"If there are people here who are proficient in medicine, there may be some anesthetics that can also cause such a death." Ling Xi replied, "To be honest, I am not at ease about your inspection, and it is not ruled out that the other party has hidden injection techniques." , so that you can’t notice it. There are also some mechanical injuries that cannot be seen on the body surface, such as suffocation caused by soft objects, and you can’t find it like this.”

Unable to draw a definite conclusion, they had to move the body back into the freezer and back into the hallway.Director Jiang was still waiting in the corridor, but he might be a little scared, so he stood a little farther away.Secretary Shen also came back, came up to tell them that they had put their suitcases in the dormitory, and gave them their room cards.

"What are you talking about...Old Cao? Are you busy now?" Lu Yuanzhe asked.

Secretary Shen nodded: "Now I'm doing experiments in 403 with two other employees, but I should be able to talk to him."

"Bold enough." Still insisting on doing the experiment, Lu Yuanzhe boasted.

"That can't be helped. The instrument is there, of course he must be there." Secretary Shen smiled helplessly, "But now there are regulations, there must be at least three people in the night experiment."

Lu Yuanzhe asked suspiciously: "Three?"

"Well, I'm not afraid of your jokes, because everyone agrees that even if there is something on the upper body, it's not enough to hit two with one." Secretary Shen shook his head as he spoke, not quite understanding this idea.But she doesn't work overtime in this building, and she doesn't have the right to speak.

"It's good to have more people. In many experiments, two people supervise each other. Dangerous reagents are still managed by two people and double locks. Now we only add one person, so everyone can feel at ease." Director Jiang is very satisfied with this emergency response.

"I think it's a good idea." Lu Yuanzhe smiled.This idea is quite creative. After watching so many horror movies, I have never seen a wraith possessing several people at the same time.
