Chapter 93 Missing
Zhou Ning dialed Zhou Xiaoyu's phone, and a female voice came from it.

"The phone you are calling is either off or out of service area."

After hanging up the phone, Liu Yongxin patted Zhou Ning's arm.

"Don't worry, if you care about it, you will be confused. Maybe Xiaoyu is in class, and my wife has a classmate who is from No. [-] Middle School. I will ask her to see if Cui Guanglin has gone to school today, so I can find out from the side."

Liu Yongxin went to make a call, Zhou Ning went to the window and directly dialed the number of Second Aunt.

"Where is Second Aunt going to work?"

"Well Xiao Ning, why did you call me?"

"It's okay. I chatted with Xiao Yu for a long time last night. I just wanted to ask you when I went back last night. You didn't talk about her again. How is she feeling?"

Second Aunt snorted.

"Later than we came back, she said she came back with you, Second Uncle Ni persuaded me, I didn't say much, she left this morning without eating, she went out very early, and didn't talk about anything else .”

"Go to school today, is there a class?"

"You boy, are you stupid at work? They have a boarding system in high school, and they have two days off every two weeks. This week is not a big holiday, and they all ask for leave when they come out on Friday night."

"I forgot in a hurry, I just asked, Second Aunt, don't worry about it, don't worry Xiao Yu is not a willful child, she understands your worries."

"Okay, don't persuade me, I know you are a good boy, I didn't say anything, you can persuade her more, I still have to pass the class first!"

After talking about hanging up the phone, Liu Yongxin also finished contacting him and was talking to Xu Dayuan, Zhou Ning hurried over.

"Cui Guanglin went back to the school last night. Zhou Xiaoyu and the others didn't see it, but they asked people to go to the Chinese teaching and research section to look for it."

A bad premonition made Zhou Ning's fingers feel cold, and Xu Dayuan waved his hand.

"Don't wait, go directly, I will find their school leaders on the way."

Several people went downstairs, Xu Dayuan had already summoned several members of the criminal police team, and the two cars drove towards No. [-] Middle School quickly.

Zhou Ning had been calling Zhou Xiaoyu's cell phone all the time, but there was no one answering it all the time. Big Zhao Yu Guang saw Zhou Ning's movements, and stepped on the gas pedal even harder.

Ten minutes later, they came to the gate of No. [-] Middle School.

Xu Dayuan had already contacted the principal, so the guard didn't stop him. The car drove straight in and stopped directly in front of the office building. When he got out of the car, he saw several teachers waiting there. Xu Dayuan ran straight to the elderly man.

"How is Principal Bai? Did you find someone?"

Principal Bai also had an anxious look on his face, pointing to the office building behind him and said:

"When I received your call, I asked someone to look for it. I searched the office building and the classrooms where they teach, but I didn't see anyone. I just asked the two teachers to look for all the restrooms, and the person hasn't returned yet."

"Do they have classes in the morning? Is it normal?"

"Teacher Zhou has no class in the morning, and there are two classes this afternoon. As for Teacher Cui, he went to their second and third classes in the morning for the first class, and then he didn't see anyone."

Zhou Ning dragged Xiao Qu and stepped forward.

"Check the monitoring, let Xiaoqu check, he is fast."

Xu Dayuan naturally agreed.

"Is the surveillance at the doorman?"

Principal Bai nodded.

"Let the security chief take you there."

Da Zhao waved his hand.

"Hurry up and get in the car with the security chief and Xiaoqu. Let's check the surveillance cameras. Do you know Zhou Xiaoyu and Cui Guanglin?"

"know."

Several people got into the car, turned around and drove towards the guard.

Principal Bai pulled Xu Dayuan and asked in a low voice:

"I said, to find someone at school, we still need to reduce panic. Can you tell me what's going on?"

Xu Dayuan shook his head.

"I also don't want to cause panic, but things are a bit special. You know that I am from the criminal police team. I can't tell you the details of the case. You just need to cooperate with us to find someone. Are all the teachers in the office building now?"

Principal Bai was stunned for a moment, but he also knew that Xu Dayuan would not ask such a merciless question if it was not a serious matter.

"There are still 10 minutes, 11:40 is the bell for the end of get out of class. I have just informed all the teachers to gather in the multi-purpose hall on the second floor."

Xu Dayuan nodded, gave some instructions to He Chunyang, and they dispersed quickly, and then said to Principal Bai:
"Principal Bai, you go to the multi-purpose hall first, find a teacher to take me to Cui Guanglin's office, and find the floor plan of the school, and ask the teacher who holds the key to follow. My people have to check all corners of the school. Doctor Liu Fayi, please follow me A teacher, go to the dormitory building of the teaching staff."

Liu Yongxin knows what this means. One is to see if there are any Tibetans, and if you have a dormitory, you can find things like hair or toothbrushes. These can be used to extract DNA. If there is really something, it can be compared.

Zhou Ning nodded to him, and Liu Yongxin followed a teacher with a survey box.

Zhou Ning followed Xu Dayuan to the third floor of the office building. The names of various teaching and research offices were hung on the doorplates, but this third floor seemed to be the teaching and research offices of the second and second departments of senior high school.

Pushing the door open, there were two teachers inside. When they saw people coming in, they naturally looked over. Xu Dayuan had already held up his ID card without the introduction of the accompanying teacher.

"I'm Xu Dayuan from the criminal police team. Please put down your work and answer a few questions for me. Have you seen Cui Guanglin this morning?"

An older female teacher stood up directly, nodded and said:

"5:40 is the time for morning self-study. I arrived at the teaching and research room at 5:35. I happened to meet Teacher Cui going out with a thermos. Looking at the direction, I went to the west building. Oh, it was their second and third grades."

Another male teacher went on to say:

"After the first get out of class, Teacher Cui and I went back to the teaching and research room. He tidied up the desk, then went out with the car keys, without saying where he was going. Just now Principal Bai called to ask, and I have already told him."

"Do you know what car he drives?"

"Teana, a silver-gray 2010 model, cost 24 yuan, and I have to pick up the car for one month."

Zhou Ning didn't wait for the teacher to speak, and spoke first.

The teacher nodded and looked at Zhou Ning with some surprise.

"Yes, it's the sound of nature. The top-of-the-line interior is all leather, but how do you know?"

"I'm Zhou Xiaoyu's brother, have you seen Zhou Xiaoyu this morning?"

Both shook their heads, as if trying to understand something, the male teacher said quickly.

"After the first get out of class, when I met Teacher Cui, I asked him, how did I meet the parents last night? Did you set a date? Teacher Cui just smiled and didn't see any special emotions. He left in a hurry, and I didn't ask any more questions."

Zhou Ning walked to the table with Cui Guanglin's brand. The table was very neat. Although there were several stacks of homework books and papers, there was not even a crease. The vacuum flask was also empty, and there was no water drop outside.

Zhou Ning opened the inspection box, picked up the thermos cup with gloves on, and scanned it, but there was not a single fingerprint. This discovery made him even more flustered. Does a normal person clean the cup without leaving fingerprints?
Then the brush swept across the tabletop, and traces of wiping appeared. Zhou Ning opened all the drawers and saw a bottle of 75% alcohol solution on the bottom shelf. He leaned over to smell the tabletop, and looked at Xu Dayuan.

"The tabletop and all items have been carefully cleaned, and there are no fingerprints left. This kind of cleaning is meaningless unless there is a special smell or... blood on the hands."

The last two words were said by Zhou Ning while gritting his molars. At the same time, he grabbed the luminol reagent in the investigation box and sprayed it on the table and thermos cup.

A crescent-shaped fluorescent trace appeared on the bottom of the thermos cup and on the table. Zhou Ning lifted the thermos cup and found that the fluorescent spot on the bottom of the thermos cup was sunken in. This should be the blood stain from the beating.

Zhou Ning's fingers were already trembling, so he quickly collected samples with a cotton swab, and the thermos cup was also put into the evidence bag.

Xu Dayuan dialed Da Zhao's cell phone directly, and the other party connected almost instantly.

"Xu Da, we quickly checked the surveillance. Cui Guanglin's car entered the campus at 08:30 last night, and the parking lot on the west side has not been touched. Zhou Xiaoyu arrived at the school gate at 07:30 this morning.

We have been looking for just now, but we did not find the two of them, and Cui Guanglin's vehicle had left the school gate. Even if there was a vehicle that went out, we did not find any traces of the two of them. "

"That is to say, confirm that they are all on campus?"

"Yes, it is confirmed that they have not left the campus. The north gate of the school cannot be opened. There are anti-crawling nets on the high walls around, and all of them are covered with surveillance. It is impossible to leave quietly. Even the vehicles entering and exiting the cafeteria are strictly unpacked here. Check, and they are all facing the surveillance, nothing was missed.”

After getting this answer, Xu Dayuan breathed a sigh of relief. As long as he didn't leave the school gate, at least the scope was limited. He immediately dialed a number, reported the things here, and mobilized his staff at the same time.

At this moment, the female teacher's mobile phone rang. She looked at Zhou Ning and pointed to the mobile phone, her eyes were asking Zhou Ning if she could answer the phone. Zhou Ning glanced at the words "Principal Bai" on it. The teacher answered.

The female teacher was quite smart, so she answered the phone directly hands-free. The principal Bai on the other side of the phone yelled anxiously without waiting for the female teacher to speak.

"Captain Xu couldn't get through on the phone. Mr. Sun told the police that Mr. Cui was found, no, Mr. Cui has already come to the multi-function hall."

When Xu Dayuan heard the movement, he hurried over and grabbed the phone.

"Say it again, where is the man?"
