When the police car stopped at the gate of the Nanshan laboratory, a young man in casual clothes quickly opened the iron door and took the initiative to come up to greet him.

"Comrade policeman, you're here. ”

"What's the situation?" Gu Chen took the lead in getting out of the car, turned on the law enforcement recorder he was carrying, and asked him, "You called the police?"

"Yes...... Yes. The young man nodded quickly and explained, "Yes...... It was I who called the police. ”

"The alarm center said that there was an explosion in your laboratory, what is the situation?" Lu Weiwei, who then walked to Gu Chen's side, also quickly tidied up her hair and put the police hat on her head.

The young man shook his head, and the whole person was also nervous, feeling extremely frightened.

Gu Chen took out the transcript and asked him lightly: "Don't be nervous, tell me what happened on your side slowly." ”

"I'm to blame for this. The young man lowered his head and said regretfully: "I was supposed to be on duty with Gao Cheng tonight, but I didn't know that this kind of thing would happen, the laboratory exploded, Gao Cheng was seriously injured, but I was not by his side, Gao Cheng might die." ”

Seeing the young man's look of repentance, Gu Chen and Lu Weiwei looked at each other, feeling that something had happened in this laboratory?

So Gu Chen asked again: "Could it be that Gao Cheng was the only one in the laboratory at that time?

"That's right. The young man cried and mourned, nodded again and again, and said, "Originally, I was on duty with Gao Cheng, but I was temporarily called out to eat by my colleagues. ”

"At that time, I thought that Gao Cheng should not have a problem with Gao Cheng in the laboratory, but when I returned to the laboratory, Gao Cheng was already lying in a pool of blood, his body was full of glass shards, and the whole person had fainted. ”

"When I arrived, Gao Cheng seemed to be almost out of breath, so I quickly called 120, and just before you arrived, Gao Cheng had just been taken to the hospital. ”

At this, the young man wiped his tears again.

Gu Chen didn't know too much about the situation at the scene, and it was not easy to make judgments, so he had to go to the laboratory to have a look, so he asked the young man, "What's your name?"

"My name is Liao Feng, and Gao Cheng and I are both Professor Zhang's assistants. ”

"Okay Liao Feng, since Gao Cheng has been sent to first aid, can you please take us to the laboratory to have a look?" Gu Chen said.

Liao Feng didn't hesitate, and directly gave up his position and said, "Then you can come with me, and I'll take you over." ”

Following Liao Feng's footsteps, everyone walked through an office building and came to a lower building in the back row of the office building.

"This is our lab. Liao Feng turned around and introduced to everyone.

At this moment, he quickly took out the key and opened the door of the laboratory.

As soon as he stepped into the door of the laboratory, Gu Chen found that the ground was full of glass residues, and all kinds of fragments were scattered all over the ground.

When the sole of the shoe is stepped on it, there will be a crunch sound from time to time.

"Wait a minute. Officer Wang stopped moving forward and said to Liao Feng, "Who else has come in here besides you?"

"No one, right? I don't know. ”

"You don't know?" Gu Chen frowned, and asked again, "When you left the laboratory, the door wasn't closed, right?"

"yes. Liao Feng did not deny it, but directly explained the situation to Gu Chen: "Because the two of us were on duty that night, I was temporarily called out to eat, so the laboratory was not closed, and I don't know who came in." ”

"But from the scene I don't know what's going on, because there are a lot of shattered pieces of glass on the floor of the lab. ”

As if thinking of something, Liao Feng said again: "Oh yes, there is also a stone with a diameter of about 18 centimeters." ”

Speaking of this, Liao Feng found the stone at his feet, so he was ready to bend down to pick it up.

"Wait a minute. Gu Chen dragged him back and prompted, "Don't move, leave this to us." ”

"Huh?" Liao Feng didn't seem to understand, and the whole person was stunned for a moment, until he saw Gu Chen start to put on white gloves, and he didn't react.

Gu Chen first held the big stone in his hand and weighed it, then turned his head and asked Liao Feng, "This stone was previously available in your laboratory?"

"No, I haven't seen it. Liao Feng said this, and suddenly hesitated, so he said: "Although I haven't seen it, this stone may be in the laboratory, but I didn't notice it myself." ”

"Then have you ever touched it?" Seeing that Liao Feng was about to carry the stone with his bare hands, Lu Weiwei couldn't help asking.

Liao Feng continued to shake his head: "I haven't touched it, I just thought it was strange before, after all, how could there be such a big stone in this laboratory?"

"I don't know who brought it in, because when I came back from dinner, I found Gao Cheng lying on the ground, with a lot of broken glass stuck in his face and chest, and he was covered in blood. ”

"Then I found this big rock on the floor, and I felt that Gao Cheng must have been attacked, so I called the police after calling the emergency service. ”

"Wait a minute. Gu Chen interrupted Liao Feng's words and asked him rhetorically, "How can you be sure that Gao Cheng must have been attacked by someone, not that some dangerous items in your laboratory exploded?"

"Impossible, absolutely impossible. Liao Feng directly denied Gu Chen's statement, and said: "We couldn't be clearer about this laboratory, there are no dangerous items at all. ”

"There was no dangerous nitroglycerin, no gunpowder, and no traces of burning at the scene, but this situation at the scene was obviously caused by an explosion, but where did the explosion come from?"

Liao Feng asked a rhetorical question, but Gu Chen couldn't answer for a while, so he could only say lightly: "Don't get excited, let me take a look at the scene first, please retreat to the door first, don't destroy the scene." ”

"Good...... Good. When Gao Cheng saw that Gu Chen, Lu Weiwei and Officer Wang had all started to put on their foot covers, in order not to block everyone, he consciously retreated to the door.

At this moment, Gu Chen, Lu Weiwei, and Officer Wang also began to investigate the scene.

Not only were glass shards scattered everywhere on the ground, but the sharp-eyed Gu Chen even found a broken glass bottle cap with a few knotted wires tied to it in a corner.

Gu Chen picked up the glass bottle cap and put the wire on his hand to observe it carefully.

"What is this?" Lu Weiwei also found out, and hurriedly walked to Gu Chen's side, squatting down to screen.

"It's like piano filament. Gu Chen also frowned, and for a while he couldn't tell why the piano wire in his hand was here, and it was still tied to the glass bottle cap in a knot.

Officer Wang walked over, stretched out his hand and said, "Then show me." ”

Gu Chen handed it to him, and then continued to search the other corners of the laboratory, but there seemed to be some doubts in his heart.

"It appears that the explosion was caused by the contents of the glass bottle. Gu Chen glanced at the broken glass on the ground, and when he connected to the bottle cap just now, he probably had some conscious judgment.

Gu Chen pinched the fragment of the bottle cap just now, put it on the tip of his nose and sniffed it, there seemed to be a smell of alcohol.

"That's weird. Gu Chen frowned, and after looking around left and right, he found that there were no so-called dangerous and flammable items around him.

And it's the same as what Liao Feng said just now.

"There was no dangerous nitroglycerin at the site, no gunpowder, and no traces of burning. Looking back at the debris on the ground, Gu Chen shook his head slightly: "But, how did this explosion come about?"

It seemed that he had also fallen into Liao Feng's doubts just now, but Gu Chen was pondering when he suddenly found that on a wooden bookshelf, it seemed to be wet and dripping.

Gu Chen hurriedly walked to the bookshelf, first stirred the tip of his nose a few times with his hand, and found that the liquid was colorless and odorless, and then gently touched the water trail with his hand.

"Isn't this just water?" Looking at the wet water trails on the bookshelf, Gu Chen suddenly pondered: "Maybe the glass bottle just now must be filled with water, but the water won't explode." ”

Shaking his head, Gu Chen called Liao Feng to his side again and asked him, "You tell me about your activities tonight, the more detailed the better." ”

"Yes...... OK. Liao Feng nodded, and only after calming down did he say: "Gao Cheng and I are both assistants to Professor Zhang, and we interned here after graduation. ”

"Tonight, Professor Zhang originally arranged for me to be on duty with Gao Cheng, but then another colleague of mine called me and asked me to go out for supper together, and he said he paid the bill. ”

"Of course I was happy to hear it at the time, after all, I hadn't been to supper for a long time, and I thought that there was Gao Cheng in the laboratory anyway, so it should be fine, so I went out with another colleague. ”

"When was the explosion, do you know?" Gu Chen asked again.

Liao Feng shook his head: "Well, I really don't know, I also returned to the laboratory after eating supper and saying goodbye to that colleague, it was quite late, and I found out that something was wrong in the laboratory." ”

"When I saw Gao Cheng lying on the ground, bleeding everywhere, I thought it was some dangerous object explosion in the laboratory. ”

"But looking back, it's not right, there are no dangerous items in our laboratory, but how did Gao Cheng get injured?"

"But it feels like someone attacked him, and I don't know what to do alone, so I called you to help. ”

"Got it. After Gu Chen looked at the scene left and right, he took pictures of the scene for evidence, and then collected some bloody glass fragments in the evidence bag, ready to take them back to the technical department together for testing by the technical department of the municipal bureau.

"Okay?" Seeing that Lu Weiwei was still searching, Officer Wang on the side hurriedly reminded her.

"No dangerous items were found. Lu Weiwei has already inspected the site three times, and it still seems that there are no so-called flammable and explosive materials at the site as previously checked.

Officer Wang said: "The most important thing now is to look at the situation in Gao Cheng, only Gao Cheng knows what happened nearby tonight." ”

"Yes. Gu Chen also clasped his hands to his chest and nodded slightly, but the whole person fell into self-contemplation.

But suddenly, the corner of Gu Chen's eyes was attracted by a dark shadow at the door.

"Who is it?" Gu Chen immediately turned his head and asked.

"I ...... I'm Professor Lao Zhang here. A middle-aged man in a leather jacket was also standing anxiously at the door at the moment.

"Professor Zhang, Professor Zhang, you are here. When Liao Feng saw him, he quickly took the initiative to walk to his side, and then introduced to Gu Chen, Lu Weiwei and Officer Wang: "Comrade policeman, this is Professor Zhang from Nanshan Laboratory, and Gao Cheng and I are both assistants under him. ”

"Hello Professor Zhang. Gu Chen took off his white gloves, shook hands with him and said, "I am Gu Chen from the Third Criminal Investigation Group of the Furong Branch. ”

"You...... Hello. Professor Zhang's attention at this moment didn't seem to be on Gu Chen's body at all, but on the inside of the laboratory.

He just wanted to raise his legs to enter the door, but was blocked by Gu Chen.

"Professor Zhang, at present, this laboratory will be temporarily taken over by our police until the matter is clarified. Gu Chen told him directly.

Professor Zhang frowned: "Can ...... But what's going on here?"

"Professor Zhang. Seeing that the professor he had notified had just arrived, Liao Feng hurriedly reported to him: "Gao Cheng is injured, covered in blood, and there are glass shards all over his body. ”

"What about Gao Cheng's people now?" Professor Zhang hurriedly asked him, and the whole person was also nervous.

"I was taken to the hospital, I guess...... It is estimated that there is more luck than luck. Saying this, Liao Feng's whole body burst into tears.

Professor Zhang remembered stomping his feet: "I said Liao Feng, what the hell are you doing here? I asked you to work the night shift in the laboratory, what are you doing here?"

"Professor Zhang: I'm sorry. Liao Feng couldn't cry, and the whole person also regretted it: "Originally, I was here to accompany Gao Cheng on duty, but later, Zhang Hao called me and asked me to go out for supper." ”

"I thought about it, anyway, there was Gao Cheng in the laboratory, so nothing should happen, so I went out for supper with Zhang Hao. ”

"But later, after I said goodbye to Zhang Hao, I returned to the laboratory to find that Gao Cheng had already fallen to the ground, and the whole person seemed to have fainted. ”

"And there was a lot of blood on my body, I felt that Gao Cheng was dying, so I quickly called 120 for first aid. ”

"That'...... Then what did the doctor say when you put him in the ambulance?" Professor Zhang's face suddenly turned blue.

Liao Feng shook his head and kept shaking his head.

Professor Zhang was so angry that he pushed him directly: "Liao Feng, you should say it quickly." ”

"The doctor said he ...... Speaking of him, it can be dangerous. ”

"What else?" Professor Zhang was so anxious that his neck was crooked to forty-five degrees, and he didn't dare to look away from Liao Feng for a moment.

"I didn't ...... No, it's gone. Liao Feng couldn't cry all over, and seemed to be in extreme grief.

Professor Zhang was so frightened that he took two steps back, his body hit the wall, and his whole face turned blue and said, "So, you don't know what's going on in this laboratory?"

"I don't know, I really don't know. Liao Feng wiped his tears and said, "If I can come back earlier, maybe I will be able to find out for the first time, Gao Cheng's blood will not flow so much, and he will not be life-threatening." ”

"It's all my fault, it's all my fault, I shouldn't have left my post without permission, I shouldn't have run to have supper at night, I'm sorry for Gao Cheng, I'm sorry for him. ”

"You all calm down first. Seeing Liao Feng and Professor Zhang crying and interfering with the investigation, Lu Weiwei came directly to the two of them and said, "We will temporarily block this laboratory first, and unrelated personnel are prohibited from entering and leaving, please cooperate." ”

"I didn't ...... No problem. Professor Zhang happily printed: "This laboratory itself is for these assistants to do research and experiments, there are no special and valuable things in it, you can seal it if you want to, but please be sure to help us investigate clearly." ”

"You don't have to worry about this. After Gu Chen completed the evidence collection work at the scene, he came to Professor Zhang and said: "Investigation and evidence collection is the work of our police, we will definitely help you find out the reason, and please actively cooperate with your Nanshan laboratory." ”

"That's for sure. Professor Zhang nodded frequently.

"Besides......" Gu Chen looked up at the two of them and asked again, "Are you the person in charge of this laboratory?"

"That's right. Liao Feng nodded.

"Then please fill in your name, ID number and phone number, if there is the latest situation that needs to be cooperated, our police will contact you in time." ”

Seeing that the two of them were stunned for a few seconds, Gu Chen asked again, "Is there a problem?"

"Oh! no...... No problem. ”

"Leave the phone number, right? ”

It was also at Gu Chen's prompting that Liao Feng and Professor Zhang respectively filled in their names, phone numbers and ID numbers on the blank pages of the investigation transcript.

Gu Chen closed the transcript, and then said, "Seal this place, and besides, go to the hospital with us to see the current situation in Gaocheng." ”

"Okay, let's go now. Professor Zhang said.

It was also after locking the laboratory that Lu Weiwei also took out the portable cordon from the tool bag and pasted it on the door.

A few people went downstairs and rushed to the emergency hospital in Gaocheng together.

Professor Zhang's car was in front and the police car was behind.

By the time I arrived at the emergency center, it was late at night.

At this moment, the light at the door of the emergency room is still on, and everyone is waiting anxiously at the door.

Looking at the light that lit up, everyone hoped that it would be extinguished soon, so that Gao Cheng could come out safely.

At the same time, they were worried that the lights would go out, leaving only a corpse.

There weren't many people in the hallway.

Gu Chen, Lu Weiwei and Officer Wang were leaning against the walls on both sides of the corridor, while Professor Zhang and Liao Feng were standing at the door of the emergency room.

It was as if the first word of news came from the emergency room, and both of them had to be the first to know.

I don't know how long I waited, Gu Chen's ears suddenly buzzed, and the light on the door of the emergency room suddenly went out.

At this moment, Professor Zhang and Liao Feng both stood up straight, while Gu Chen, Lu Weiwei and Officer Wang all looked at the door.

It seems that the doctor who is the first to come out screams will notify him of death or survival.

"Crunch!" the door opened.

As soon as a middle-aged man in a surgical gown went out, Liao Feng rushed over directly and grabbed him with both hands.

"High Castle ...... Are you still alive?"
