Friday, March 12, afternoon.

After school at Didan Elementary School, the Junior Detective Corps, organized by the head of the group, Yuantai, went to play football together, and although Conan and Gray Yuan were reluctant, they could only obey the majority in the minority.

After a long time, Didan High School was out of school, and Ran, Yuanzi, Mei Daiko, and Yamazaki passed by in the distance with their schoolbags, and saw that the young detective group was having fun, so they didn't call them.

At this time, a passing medium-sized trailer caught Yamazaki's attention, with yellow text on the black body - Bio, which was a biosafety vehicle belonging to the Good Mood Experimental Department, which would only be dispatched when there was a laboratory accident in a biological laboratory or research institute.

The biological laboratory near here should be the biological laboratory of Rice Flower University, and it seems that there was an experimental accident there.

"Let's go, let's go to Rice Flower University. Yamazaki suggested, "I saw the biosafety vehicle, and something seemed to have happened to the biolab there. ”

Lan asked, "Biosecurity car?"

"It's just dealing with bugs or something. Mei Daiko said.

"I don't know if I've watched too many movies, it sounds a little scary. The garden said timidly. ……

On the other hand, Gray Yuan also noticed that he had seen the rescue mechanism in the underground laboratory of the 2-chome Asai Xiang family, like if there was a laboratory accident in the underground laboratory, there would be white text on the black car body - a medical car, because there was no direct danger in the experimental accident in the underground laboratory, at most a small amount of drug pollution and sewage.

Of course, if you build Teenage Mutant Ninja Turtles there to play, that's another problem.

"What are you looking at?" asked Conan.

"It's a biosafety car, and yellow means it's dangerous. "It should be an experimental accident in the biology laboratory of Rice Flower University." ”

"Rice Flower University's biology lab," Conan said after a moment's thought, "I heard that it is for spiders." ”

"It's by studying spiders to study spider silk," Gray Hara said, "to make armor that is bladeproof and bulletproof." ”

Conan said, "You know that very well. ”

"I've been on a research platform in the web and have advised on genetic modification options for spiders. ”

"Uh......" Conan was speechless.

"What spiders are you talking about?"

"It seems to be funny. ”

"Let's take a look. ”

Mitsuhiko, Motota, and Ayumi immediately ran over, and Conan and Gray Hara reluctantly followed. ……

On the way, a police car also appeared, it was the criminal police, the Twilight Police Department and Officer Takagi, Conan suddenly cheered up, there was an incident.

Gray Yuan said angrily: "Experimental accident, don't think about going in." ”

Conan was immediately a little discouraged, and then found Lan in front of them, and immediately became happy again, maybe he could sneak in and have a look. ……

Rice Flower University, Biology Laboratory.

The periphery of the all-metal mansion in the single courtyard was full of people watching the excitement, and the police came forward to invite everyone out of the courtyard.

The Dusk Police Department showed their ID, "What's going on here, who called the police?"

"Officer, I called the police. A man in a white coat came up and said, "I'm Assistant Professor Toru Itokawa, and I received a call from Professor Yutaka Niinno, who shouted on the phone that he had been bitten by a red-backed spider, and then before I could speak, Professor Nino was silent." ”

The Twilight Police Department asked, "What about Professor Shinno, who was sent to the hospital?"

Toru Itokawa said, "Well, Professor Yutaka Nishino is still in the lab. ”

"What!" the Twilight Police Department was surprised.

"Please come with me. Itokawa took the Twilight Police Department to the monitoring room and called up the video, in which a middle-aged man suddenly screamed excitedly when he made a phone call, threw a small spider on the table, and then fell to the ground.

The Twilight Police Department was startled, "What kind of spider is this, did he die of poisoning?"

"It's unclear, but it's certain that the venom of the redback spider isn't so lethal as quickly. "According to the lab's procedures, I called a biosafety vehicle, and we couldn't go in until a professional had checked it." ”

"Didn't call an ambulance?" asked the Twilight Police Department.

"Officers, they're professional ambulance crews. Itokawa said, "Until they confirm it, I can't let ordinary people in, because I don't understand the situation, and I was bitten ......to death by a spider."

"Huh?" displeased the Dusk Police Department, "Is this still a trivial matter?"

"Officer, you don't understand. "There are a lot of alien spiders in this laboratory, as well as artificially modified mutant spiders, no matter what kind of spider it is, if you take advantage of the chaos to escape from the laboratory, it is likely to breed with our local spiders, causing species invasion, and the consequences can be big or small." ”

Officer Takagi is speechless, an American disaster movie?

The Twilight Police Department frowned, "In that case, how did this lab build here?"

"Don't worry, officer, this biological laboratory has perfect security measures and fully complies with the relevant regulations of the state. Itokawa said, then sighed, "But there is no way to prevent man-made accidents. ”

The Twilight Police Department asked, "Why do you say that about a man-made accident?"

"That's right, this lab is under surveillance 24 hours a day," Itokawa dialed the footage, "but you see, part of the video is missing, and the video from 2 p.m. to 4 p.m. has been completely deleted, and I suspect that someone erased it." ”

The Twilight Police Department said solemnly: "That is to say, someone moved his hands and feet, causing Professor Yutaka Nishino to be bitten by a poisonous spider. ”

"Yes, that's what I thought. Itokawa called up the list of personnel, "The only people who have permission to enter and leave this biological laboratory freely are the professor and me. ”

The Twilight Police Department asked, "Then you are also suspicious?"

"I have a full alibi, I'll tell you more about this later. Toru Itokawa continued, "The two people who plan to visit the professor today, pet merchant Yoshiki Urasaki and magazine editor Miwa Yasuda, as well as these interns, if they come to the professor, they may get access to the lab from the professor. ”

The Twilight Police Department looked at it with a little headache, "Takagi, you make a note of the personnel list." ”

"Yes. Officer Takagi replied.

Itokawa hurriedly said, "No, no, I'll print it out for you right away." ”

"Uh," the Dusk Police Department was a little embarrassed, "thank you then." ”

Moments later, the list of personnel was printed, with names, contact details, and home addresses.

"Takagi, take someone to look for it. The Twilight Police Department glanced at the list.

"Yes, police department. Officer Takagi took the list and left.

The Twilight Police Department said, "So, Mr. Itokawa, please tell me about your alibi." ”

Toru Itokawa said: "From two to four o'clock in the afternoon, I have a class, and although there is a break in the middle, the class location is a little far from here, and I can't rush back and forth. ”

"I want to be a minute or two late, or skip class......"

Toru Itokawa interrupted, "I'm sorry, officer, you misunderstood, I'm talking about teaching for students." ”

The Twilight Police Department was a little embarrassed, "I see." ”

At this time, the rescue team carried out the body of Professor Yutaka Niino and explained the situation to Toru Itokawa and the Twilight Police Department.

It is preliminarily inferred that Professor Yutaka Shinno did not die of poisoning, but died of a heart attack caused by poisoning.

Professor Yutaka Nishino has a mark on his ear that appears to have been bitten by a redback spider.

The red-backed spider died on Professor Yutaka Shinno's desk, and all living things in the lab were intact except for this red-backed spider.

The alarm in the laboratory is cleared and you can enter.

The rescue team left, taking the original video hard disk, and went back to see if it could recover the data, even if the police took it, they had to get it back because of the manufacturer, so the Dusk Police Department didn't take it.

The Twilight Police Department sent the body of Professor Yutaka Nishino to the Metropolitan Police Department, spider venom, if the algorithm doctor can't handle it, you can also ask the relevant biological experts for help. ……

After that, Itokawa Toru took the Twilight Police Department to the scene, "That's the area where the spiders are raised, this is the experimental area, and the place where Professor Nishino fell is in the research area, this could only be someone who brought the spider out, it's not the professor, it's someone else." ”

On Professor Nishino's desk, there was a small glass cover, and inside was a spider no bigger than a finger, with a black and bright belly with red hourglass-shaped spots, and now it was motionless and dead.

The Twilight Police Department asked, "Is this spider biting Professor Shinno?"

"It's supposed to be a male red-backed spider, and its venom can be fatal, but it usually takes a few hours or more, but its venom has paralyzing properties, maybe because the professor happens to have a heart attack, so the professor was poisoned and caused a heart attack, and the result was a tragedy." ”

The Twilight Police Department said, "Okay, now is the job of our police, investigating the killings. ”

Toru Itokawa said, "Then please, please be sure to find out the murderer of the professor." ”

The Twilight Police Department asked, "Anyway, why are there only the two of you in this big laboratory?"

Toru Itokawa said, "Originally, there were a lot of people, because some of the projects have ended, and they went to transform the results. ”

"Uh," the Dusk Police Department asked, "Excuse me, what are you doing?"

"The lab is mainly studying spider silk," Toru Itokawa said, "The professor's job is to observe and raise spiders, my job is to breed new species of spiders using emerging genetic technology, and others use the spiders we provide to pair up to produce new spiders and study the spider silk that these spiders spit out." ”

"Spider Silk?" asked the Dusk Police Department, puzzled, "What's the use of that?"

"Lots of uses. "For example, sutures that can be absorbed, so that there are no unsightly scars left after surgery, which is useful for you police officers who are often injured." ”

The Twilight Police Department is speechless, although you mean well, but don't say such things, okay?

At this time, Officer Takagi returned, and Itokawa went to pick up Officer Takagi and entered the laboratory, along with a man and a woman. ……
