today's island

The "Old Cao" Director Jiang mentioned was called Cao Zhijie. He seemed to be nearly 40 years old, but he was still quite strong.Originally, he was looking at the experiment records with a sad face, but when he saw Lu Yuanzhe and Cheng Mo enter the door, he immediately stood up: "Comrade police?"

"Hello." Lu Yuanzhe reached out to him, "Lu Yuanzhe, Cheng Mo."

"Hello, two, if you don't come, we really can't take it anymore." Cao Zhijie held his hand tightly, looking like he saw the savior, and the two apprentice experimenters he brought hurriedly Stand up and give them your seat.

"No, no." Lu Yuanzhe waved his hand, "You guys are busy, we just came to take a look."

This small laboratory is equipped with an air conditioner and a fume hood. Although there is hydrogen gas, it is also inflammable and explosive, so it is unlikely to be poisoned.

The laboratory has its own layout specifications, and there is nothing but two instruments. The drawers are full of replacement components, and there are no dangerous goods.

"Which floor are your samples on?" Lu Yuanzhe asked, "Is the sample room safe? Who can go in?"

"On the third floor, 310, there is no danger. They are all non-pathogenic microorganisms. There are eleven people who can get in." Cao Zhijie introduced.

"The authority of the access control can be seen here." Secretary Shen handed Lu Yuanzhe a tablet computer, "From the gate to each room, the time of entry and exit can be checked on this."

Lu Yuanzhe followed the prompts to check the permissions, and Cheng Mo also came over.This is an access control monitoring system connected to the intranet. From this point of view, there are more people who can enter 403, forty or fifty, while only a few people who are doing microbiological experiments and leaders can enter 310.

Last night, He Zhigang was the only one who clocked in these two rooms. He didn't go to other rooms either.

"Is it possible for this access control system to be artificially modified?" Lu Yuanzhe asked.

"It's not necessary..." Secretary Shen frowned, unable to think of anyone who could do such a thing, "If someone really harms Xiao He, it's better to do some tricks in the experiment, everyone is an experimenter, exposed to high-risk chemicals Not difficult."

"No one will harm Xiaohe." Director Jiang cut in immediately, and gave Secretary Shen a restraining look, "We only have one department that does the program design of detection instruments, and I'm afraid there are not many people who are proficient in computers. It’s not on the island, so it’s impossible to change it randomly.”

"Xiao Shen, don't talk about things that are not harmful." Cao Zhijie was also quite taboo about this topic, and suddenly became nervous.

Cheng Mo glanced at Lu Yuanzhe, and raised his breath halfway to ask a question.

"By the way, do you have any water here?" Lu Yuanzhe asked suddenly.

"Generally, there are no water dispensers in the laboratory, why don't Captain Lu go downstairs with me to drink?" Secretary Shen asked.

"Okay." Lu Yuanzhe nodded, and patted Cheng Mo's shoulder, "Aren't you thirsty, take a few photos and go downstairs."

"Got it." Cheng Mo responded and took out his phone.

"Director Jiang, let's go downstairs together. I still have some questions about the planning of the research institute." As he said that, Lu Yuanzhe leaned into Director Jiang's ear and asked in a low voice, "The research institute does not work overtime in violation of the regulations. It is mandatory not to take vacations or send Overtime pay, squeeze the labor force of employees, right?"

Director Jiang's eyes widened all of a sudden, and he looked at Cao Zhijie vigilantly. He didn't want to discuss these issues in front of Cheng Mo, so he waved his hands desperately at Lu Yuanzhe: "No, no, Captain Lu was joking, we are a high-end research institution after all."

Lu Yuanzhe smiled, joked with him, and dragged him downstairs.

As soon as they left, Cheng Mo's photo was taken, and then he looked at Cao Zhijie: "Master Cao, can you show me your access control?"

"Ah?" Cao Zhijie was stunned for a moment, "Yes."

The two of them moved outside, Cheng Mo closed the door, his voice became much softer, but he still retained full sincerity: "What do you want to tell us?"

In the empty corridor, only Cao Zhijie and Cheng Mo were standing. After more than ten seconds of silence, Cao Zhijie finally felt relieved.

"Yes..." He rubbed his hands, hesitated for a moment, and said what had been in his heart for a long time, "Xiaohe told me several times last night that there was a ghost in the laboratory building, and asked me to accompany him to do the experiment. Then, I was very sleepy, and I thought it was young people who were timid, so I didn't take it seriously, and it turned out..."

"Do you think there is a problem here?" Cheng Mo asked.

"Of course it's impossible to be haunted. It's been a few years, how could such a thing happen suddenly." Cao Zhijie frowned, "But..."

But something happened to the person, and he couldn't find a single wound on his body. Who knows what the hell was going on.

"But something happened to him after he went back." Cheng Mo said, "You found out."

"That's right, if you don't cut the anti-theft chain, you can't get in at all. No one can harm him... I don't believe in ghosts... So I was wondering if Xiaohe was too nervous, stayed up all night, and collapsed all of a sudden. Cao Zhijie lowered his head, regretful, "If I knew he was so scared, I should have gone together."

After getting a general understanding of the situation, Cheng Mo comforted: "Sudden death is usually caused by some sudden illness, and it is not all caused by external factors. Don't think too much about it."

"Well, it would be great if we could find out the cause of the disease." Cao Zhijie sighed, "But everyone wants to make big things smaller, and if someone dies, it will have a great impact on funding."

This is indeed the most worrying issue of the entire institute. Once it becomes a case, it will have a great impact on the funding of the institute.

After saying goodbye to Cao Zhijie, Cheng Mo took the elevator downstairs, still thinking about "haunting".

When it comes to being haunted, the most likely thing is that someone sneaked in.But apart from monitoring, this is indeed a research institute with very complete security measures. It relies on central air conditioning to keep the temperature and ventilation, and there are no windows that allow people to pass through. All doors require access control cards. He couldn't think of any way to sneak in.

Besides, what's the use of sneaking in here?He Zhigang was killed in his room.

Lu Yuanzhe and the others were waiting in the lobby. Lu Yuanzhe was still holding a glass of warm water and handed it to him.

"Thank you." Cheng Mo took the water and nodded at him, indicating that he had answered all the questions that should be asked, so they left the laboratory building together and went to the last stop.

He Zhigang's room was even simpler. Only the anti-theft chain had been violently damaged, and there were no signs of forced prying on the doors and windows. The transom was open, but small animals could get in through such a small gap, and it was difficult for children to pass through.

There is no peculiar smell in the room, and there are no sundries; the clothes in the closet are neatly folded; there is a private washing machine, laundry detergent, softener, and disinfectant are all available. He is a boy with cleanliness and obsessive-compulsive disorder.

There are two experimental notebooks beside the bed, recording numbers and letters that Lu Yuanzhe and Cheng Mo cannot understand. The computer can run normally, but no one knows his power-on password.

The two of them read the contents of the USB flash drive under the guidance of Secretary Shen. They were also all experimental data. This was listed in the header, so they could understand it a little bit.More than half of them are qualitative and quantitative of microbial gas production, conversion rate of chemical reaction, extraction rate of some complex organic matter, and experimental conditions. There is really nothing suspicious.

"I shouldn't drink that glass of water." After checking around, Lu Yuanzhe suddenly got into the bathroom.

This was as sudden as drinking water, Director Jiang couldn't help looking at Cheng Mo.

"I didn't find anything wrong, maybe it's just overwork." Cheng Mo smiled innocently again, and calmly narrated to Director Jiang, "It depends on whether his family can understand."

"Human life cannot be saved. We will do our best to compensate you." Hearing what he said, Director Jiang was relieved a lot. "We will try our best not to cause trouble. You are the son of Mayor Cheng, so you must understand."

"We are also very sorry, he is still so young." Secretary Shen added.

Lu Yuanzhe came out soon, with the same meaning as Cheng Mo: "There is nothing suspicious, I guess my body can't handle it anymore, and now all kinds of cardiovascular and cerebrovascular diseases are getting younger."

"What a pity..." Director Jiang didn't know whether he was relieved or sighed, but he sighed with emotion.

After a few pleasantries with Director Jiang, the on-site investigation is over.Before dinner time, Lu Yuanzhe and Cheng Mo planned to go back to their room and sit down.

Director Jiang only sent them to the door of the room and said that he was busy when he went back. Secretary Shen accompanied them into the room and introduced the water and electricity equipment to them.

I walked back and forth in the corridor and didn't meet anyone. It seems that the typhoon fake research institute is indeed very empty.Their room is on the second floor, on the first floor as He Zhigang's room, and the layout of the room is similar, like a student dormitory, only a little bigger.

"That's right, it's still a double room." Lu Yuanzhe looked at their room, it was clean and simple, and he didn't mean to treat them differently just because they were criminal police officers.

Secretary Shen was stunned for a moment, and quickly asked him: "Is it not good? How about changing two private rooms for you?"

"No, it's very good." Lu Yuanzhe replied, and glanced at Cheng Mo, Cheng Mo smiled and agreed.

Dinner was served at six o'clock in the evening, and there were still two hours left. Secretary Shen said that they could rest for a while, and then said goodbye.After seeing off Secretary Shen, the two finally began to exchange information.

"How is it?" Lu Yuanzhe asked Cheng Mo.

"Master Cao said that He Zhigang wanted him to go with him last night, but he didn't take it seriously." Cheng Mo replied, "But he tends to be scared to death, mainly because he feels that he has not fulfilled the responsibility of his predecessors, and has not gone to He kills suspicion."

"I have some doubts here." Lu Yuanzhe said, "He is an extremely clean freak, but I just walked around his bathroom and found that he washed his clothes and wiped the bathroom last night, but the toilet was not closed. "

"Huh?" Cheng Mo's recording hand stopped for a moment, "Is this suspicious?"

"Forget it." Lu Yuanzhe nodded, "People who are obsessed with cleanliness will definitely cover it at any time."

He Zhigang is not only obsessed with cleanliness, he should be regarded as extremely cleanliness, and he can't fail to notice this.

"Then what do you think, someone went to find him last night and murdered him?" Cheng Mo asked.

"It's hard to say if it was murder, anyway, at least someone visited him last night." Lu Yuanzhe replied, then frowned, "But if it was homicide, it's really a secret room murder."

"No matter what the method of killing is, without definite doubts, it is still very difficult for us." Cheng Mo recalled the attitudes of the few people he met, "Although I think they have indeed failed to deal with the family members, we cannot guarantee that the family members will persist. Thorough investigation, after all, the research institute wants to close the case quickly, and is willing to spend a lot of money to settle the matter."

"Of course, they still have the government as their backer, and your dad doesn't want to make trouble, maybe they still want you to stand by them and let your dad lend a helping hand." Lu Yuanzhe shrugged and glanced at him , "Take it easy at night, there may be a tough battle to fight at night."

Cheng Mo looked at him suspiciously, and Lu Yuanzhe explained helplessly: "What do you think you have for dinner tonight? Box lunch?"

The entire research institute hoped that the major incidents would be reduced to minor ones. Of course, it would be best to resolve them in a happy drinking session.
