Chapter 96 I'll Be There in 5 Minutes
10 minute later.

Zhou Ning came to the third floor of the staff dormitory building, and Liu Yongxin was waiting on the second floor. This floor has not been found yet. After all, Cui Guanglin is a person with a low sense of presence, and he was also searching for Zhou Xiaoyu here.

Seeing Zhou Ning coming, he quickly followed upstairs, but there was no one in the dormitory.

"Open the door and let's check."

With an embarrassed expression on his face, the guard spread his hands and said.

"It's not that we don't cooperate. The teacher's dormitory keys are all in their own hands. The old man checked just now. We all look at a dormitory to find someone to open a door."

Liu Yongxin followed suit and nodded.

"I checked several dormitories downstairs, but I just needed to contact the teacher to open the door, but everyone was in the multi-purpose hall, so I couldn't find Cui Guanglin's dormitory."

"How many teachers are there in this room?"

Zhou Ning glanced at it and saw that there were two bunk beds in the dormitory. According to the layout, there were beddings on the three beds. Obviously, besides Cui Guanglin, there were two teachers living here.

While talking, a male teacher came over, held up the key and said:

"I have the key!"

Zhou Ning glanced, this person is the teacher I met in the chemistry teaching and research section just now.

"Let's check first. If there are any dangerous items hidden, it will be safe for you to find them."

The teacher smiled.

"I understand."

With that said, the door opened, Zhou Ning and Da Zhao approached the room carrying the survey box, some liquid was sprinkled on the ground and bubbles appeared on the edge, Zhou Ning squatted down and did not rush over, but stopped Da Zhao and found a piece of test paper dipped in liquid.

When the test paper was thrown down, it seemed to be carbonized and turned into a pitch black color. The teacher covered his mouth and let out an exclamation.

"Sulfuric acid, this is concentrated sulfuric acid!"

Zhou Ning nodded. The chemistry teacher is still very good. You can guess what substance it is when you see this.

However, the area where the liquid was spilled was not large. Zhou Ning looked towards the source, and a brown glass bottle was broken in the corner of the room. Obviously, the sulfuric acid bottle fell and the liquid spilled out. However, this thing can be placed in the dormitory, which makes Zhou Ning a little scared .

"Big Zhao looks for a special evidence box, picks up the fragments of the bottle, be careful not to touch the liquid, and don't touch the gloves."

The flesh on Da Zhao's face trembled, and he quickly squeezed together, put these pieces into a glass box, and then carefully closed the lid.

"Which bed and cabinet belong to Cui Guanglin?"

The male teacher pointed to a bed by the window and said:

"Just the bed, the cabinet by the window and the desk are his."

Zhou Ning walked over, the bed was very tidy, not to mention the hair, there was not a single wrinkle on the bed sheet, and when the mattress was lifted, there was nothing hidden underneath, and the cabinet was even more empty when opened, just a washing basin with toothpaste, toothbrush and soap.

Zhou Ning didn't give up. There was a broken bottle of sulfuric acid at the door. It was too late to clean up. The place is so clean. Could it be because someone came and disturbed him?

No, something must have been missed.

But the room is so big, everything is clear at a glance, Zhou Ning glanced out of the window, and opened the window, the window of this room faces north, the north wind quickly poured in as soon as it was opened, and Da Zhao came over from behind.

"There's nothing here. Could it be that he turned off the light rain and hid here for three hours? Is there any point in that?"

Zhou Ning didn't speak, he stepped forward and stood by the window, and leaned half of his body out. At this moment, he saw a plastic bag hanging on the edge of the small decorative guardrail outside the window. The sill was on the window.

Da Zhao didn't dare to speak, so he hurried over to support Zhou Ning. This is the third floor, although it is not high, but the whole person is squatting at the window, which is still a bit scary.

Zhou Ning didn't touch it directly, but poked the plastic bag with a swab. The bag swung around, but there was no reaction on the swab. Then Zhou Ning picked up the plastic bag with tweezers and handed it to Da Zhao.

Liu Yongxin shouted from behind:

"Don't pick it up with your hands, handle it gently."

Da Zhao trembled, grabbed an oval tweezers, caught the bag and put it on the table, helping Zhou Ning to jump down.

Zhou Ning operated two tweezers together and opened the bag. There were four brown glass bottles inside, which were exactly the same as the sulfuric acid bottle just now. Da Zhao came over and quickly took pictures.

"I'll go. There are still four bottles here. Could it be sulfuric acid in them?"

Before Zhou Ning could speak, Liu Yongxin came over and shook his head.

"Take the things back, Dr. Lu is still there, he is a professional, let him make the distinction."

Da Zhao didn't talk nonsense, so he quickly found a box and put the things in it. There is a high probability that this thing is sulfuric acid. If it falls or breaks, it is dangerous and must be kept well.

Seeing that Zhou Ning was about to leave, the teacher pointed to the sulfuric acid liquid on the ground.

"How do we deal with it here, can it be cleaned up?"

Zhou Ning nodded.

"It has already been sampled, and there is no need to keep it on site. Please clean it up. I think you are more professional."

The man breathed a sigh of relief, and quickly poured water into the room. After all, it wasn't much, so it would be fine to dilute this amount and clean it up, without hurting anyone.

After half an hour.

Interpol.

Zhou Ning jumped out of the car with his things in his arms, Da Zhao was holding the box, and Liu Yongxin followed behind. The three of them hurried to Dr. Lu's office. Those who needed to be sent for inspection had already been sent by someone on the way, but the ones in the bag were left Four brown bottles.

"Dr. Lu, please help me to take a look. This is the bottle found outside the window of the suspect's dormitory. A sulfuric acid bottle was broken on the floor of his room, and a little bit was scattered on the ground. I'm not sure what these substances are."

Dr. Lu happily leaned over, hurriedly asked someone to take the bottle, and said thoughtfully:

"Don't destroy the outer bag. Zhou Xiaozhou still needs to extract fingerprints. This is also evidence for them. By the way, let's extract the outside of the bottle first. Just give me your powder and brush. We can do this."

Zhou Ning naturally didn't talk nonsense. Da Zhao and Liu Yongxin have been tossing with him until now, but they haven't eaten, and he feels sorry, so he quickly left the relevant tools.

"Then thank you Dr. Lu, let's go eat something."

"Go quickly, just now Xu Da arranged for someone to bring you a box of lunch, you have been tossing to this point, hurry up and eat."

Liu Yongxin waved his hand.

"You guys go to An'an to have dinner with peace of mind. I will follow you to the Municipal Bureau. The amount of inspections this time is very large, and the various inspections are very complicated. Xiao Liu explained that I am afraid that there may be some omissions."

Zhou Ning was a little worried, but of course he was more apologetic.

"Master, let's go after eating."

Liu Yongxin rolled his eyes.

"Stop talking nonsense, listen to me and listen to you."

Speaking of Liu Yongxin's departure, Zhou Ning knew that the master was worried about him, and it was true that Xiao Liu couldn't explain it clearly by himself, and it was easy to make mistakes. The master followed, and the detection speed was naturally fast.

Thinking of this, he immediately dragged Zhao Xinli out of Dr. Lu's office. Big Zhao looked astonished and looked at Zhou Ning several times, as if observing Zhou Ning's state.

"I said, why are you not in a hurry, Cui Guanglin is interrogating, and Xiao Yu is still in the hospital, what's the hurry?"

Zhou Ning shook his head.

"Cui Guanglin is not in a hurry. He won't explain in a short time. We have to wait for the test results. Only when the comparison is successful can we talk about the next step. As for Xiaoyu, there is nothing good about it. Instead, we have to eat well. It gives me the energy to do more things.”

Da Zhao sighed, although Zhou Ning said so, he also knew in his heart that Zhou Ning was really anxious, and it was the kind of anxiety that couldn't be helped, the calmer he was at the moment, the more uncomfortable he felt.

"That's up to you, let's eat first!"

The two washed up, quickly resolved the battle, and poured a large glass of water. Then Zhou Ning dialed He Shancun's cell phone, and the phone rang, and the other party connected.

"I'm still wondering, why are you so calm and don't care about your sister's condition?"

"It's up to you, I don't worry."

He Shancun smiled. He was very satisfied with Zhou Ning's answer.

"Xiaoyu is in good condition. The wound on her head is not deep. She has had six stitches and her hair hasn't been shaved too much, so as not to affect her appearance. I have had various blood tests done on her, and no problems have been found so far.

Nurses have also carefully checked the body, there is not a single needle hole, but if the person is unconscious after inhaling the anesthetic, it cannot be detected in the blood, after all, it was already five or six hours ago. "

Zhou Ning knew that the testing conditions in the hospital were limited, and now he could only wait for the results from the testing center.

"I know, as long as there is nothing wrong with Xiaoyu, and the nurse you asked to check Zhou Xiaoyu's body?"

"Ah, what's the matter? Can I go and check?"

"Come on, I mean, I didn't find a female doctor to examine her carefully. I'm afraid she has some injuries on her body, or... let's put it this way, among the few dead people found in the previous case, four were One is positive for HPV, one is positive for HIV, I can't tell whether it's their own virus or the killer's problem."

He Shancun was stunned for a moment, and his face became serious.

"I understand. I'm going to do a physical examination and related tests now. Why didn't you tell me earlier, have you collected the blood sample of her scumbag boyfriend? Is there a screening for related viruses?"

"His delivery was delivered at noon. I just thought of Xiao Yu just now, and I still want to check and rest assured. If it's done, I'll hang up."

After finishing talking and hanging up the phone, He Shancun pinched the phone and misplaced his teeth, feeling a little careless in making friends.

Glancing at the intern next to him, that person shrank his neck in fright, wishing he could bury his face in the display screen.

He Shancun dialed a number, but the other party didn't have a good attitude when he got through.

"When Director He received your call, my calf hurts. What's wrong?"

"Hey, it's a personal matter. A friend's sister was sent to the emergency room in a coma. We are not sure if she was violated. After all, the suspect has been arrested. This person has many diseases. He has both HIV and HPV. It is you who Have a look?"

"5 minutes, I'll be there!"
