Chapter 337 Uncle Policeman, You Are a Hacker
In a word, everyone already knows who the caller is. Director Sun is now the director of the Qidong branch. Although he doesn't have Xu Dayuan's ridiculous promotion speed, he is still a real leader.

Old Liu seemed to have thought of something, his eyes lit up, and he moved to Xu Dayuan's side. Xu Dayuan had no choice but to turn on the speakerphone, and the sounds of turning pages and typing keyboards in the room also stopped cooperatively.

"Didn't you ask us to cooperate? When I thought He Chunyang went to find Cheng Zhi, the boss of Fireworks, it seemed not serious enough, so I called him personally. In addition, have you forgotten that I handled this case back then. Why don't you just tell me?"

Xu Dayuan smiled awkwardly.

"Hey, how can I forget this, I'm not thinking that if He Chunyang can do it, he won't bother the old leader."

"Stop messing around with me. You are my leader now. I'll take Boss Cheng and the child there in a while. As for taking pictures to check your fingers, I think Zhou Xiaozhou can do it. It's better for you to see it yourself."

Xu Dayuan naturally had no objection.

"Okay, but is the child going to class today? Shall we come together?"

Sun Ju snorted twice, not to mention some details of Xu Dayuan, he was really similar to Sun Ju.

"Stop playing with me. I told Boss Cheng that I encountered a case that was very similar to the kidnapping of his son. After police analysis, the young man didn't look like the real culprit. The real culprit was not caught. The possibility of retaliation is not impossible, after all, the new case involved tearing up the ticket."

"I've learned that, Director Sun is still old and cunning, so I won't be polite to you anymore, call me when you come."

After Xu Dayuan finished speaking, he quickly hung up the phone, and he could vaguely hear Director Sun's furious voice coming from the microphone. Seeing that he hung up the phone, everyone started to continue the work at hand.

Seeing Xu Dayuan hang up the phone, Zhou Ning pointed to the door.

"Since Bureau Sun will be here soon, I'll go and study the inspection report first, and we'll collect it after we meet Bureau Sun and the survivor of the kidnapping, shall we?"

Xu Dayuan didn't object, they returned to the laboratory, Zhu Xingxing and the others seemed to be looking at something, Zhou Ning walked over and asked subconsciously.

"Have you found anything?"

Zhu Xingxing raised his head and saw Zhou Ning and the others coming back, so he stood up from the ground, but it seemed that his feet were numb after squatting for a long time, and they fell to one side together, and Da Zhao hurriedly supported her.

"What's wrong, what are you squatting on the ground to study, don't know where to sit? Hurry up and stomp your feet."

Zhu Xingxing gave him a blank look, struggled a little embarrassedly, pointed at the inspection report with a thumping leg and said:
"Boss, look, we rearranged the chemical substances found on the clothes of the deceased, asked Sister Cui for the original test records, and asked Dr. Lu about it.

Dr. Lu said that the combination of sulfur, nitrogen, oxygen and other compounds in this proportion should be a special kind of grease, which is not used in ordinary cars or ships.

Because some special particles in it are more like a kind of grease used by the navy, and this grease is generally solid and needs to be applied to the wearing parts to reduce friction. It is mostly used for high-precision wearing parts of ships. "

Zhou Ning frowned slightly. This discovery, together with the analysis of the murder weapon before, made Zhou Ning have to suspect that the murderer had some special identity.

Da Zhao took the record and looked at it carefully, with a rare serious expression.

"I'll ask my old man to see where these things are used and who can access them."

After talking about Da Zhao, he walked away. In fact, Zhou Ning never asked about Da Zhao's family background, but Zhou Ning could guess one or two. He grew up in a military compound, and his parents were in the army. some important jobs.

After waiting for a long time, Da Zhao came back.

"My dad said that this kind of solid grease is unique to them. There are many people who can contact it, mainly the personnel in charge of ship maintenance. Taking this thing back is of no great use, so the control is not very strict.

However, this kind of grease has defects in high temperature resistance, and now it is more advanced. It is a newly developed grease, and its composition has changed a lot. It can be regarded as an obsolete product before 2003. "

Although this sentence is very general, it also locks in a scope, the navy and ships, such personnel can get this kind of grease, especially the timeline before 2003.

If this person was also responsible for the kidnapping in Qidong in 2000, then this person may have served as a soldier and joined the army before 2000. Although recruits have holidays, they cannot come out, so the time for enlisting in the army should be earlier, even at this time May have been retired.

But what is he doing with this grease?
Is it for tool maintenance?
Thinking of this, Zhou Ning took out his mobile phone and dialed Cui Lili's number, but the other party answered in seconds.

"what happened?"

"Sister, let me ask. Just now Zhu Xingxing said that the fat on the deceased's clothes had many chemical components analyzed. Then I would like to ask if similar tests have been done on the wounds of the deceased. Are there any similar components?"

"I just checked my work notes. It is true that I did the comparison, but it was submitted by Cui Haibin's group for inspection. Although the wound extract was collected in it, there was no reminder to perform a chemical residue comparison, so I did not Give them the corresponding report, I will look through the experimental process records later, I think I should keep the bottom line, find me and send it to you."

Thank you, Zhou Ning hung up the phone, and Liu Yongxin came over.

"Apprentice, do you suspect that the murderer used this as lubricant to maintain this three-edged bayonet?"

Zhou Ning nodded.

"Otherwise, I can't think of the purpose for him to save this grease. After all, it is difficult to use such high-density grease in life. Maybe it is a habit, in order to prevent corrosion and rust for knives."

Liu Yongxin nodded, he still agrees with this analysis.

"It is indeed possible, but according to this analysis, the murderer's identity may be a retired soldier. If this identity can be confirmed, then he can escape the arrest of the two kidnapping cases on February 2000, 2.3 and April 2004, 4.14. It can indeed be said that Makes sense."

Zhou Ning did not speak, staring at the information sorted out on the glass whiteboard, carefully watching.

But his heart was already churning. If the murderer really had this identity, then the difficulty of this case would increase again. But why did he choose Zhu Yantao's family to start?
Could it be because of Fang Yue's identity?

It stands to reason that a semi-retired actor should not attract a lot of attention, unless it is a popular saying that he has an illegitimate meal, but Fang Yue is not very popular, and only one film he participated in can be sold, if not Killed, I am afraid it has long been forgotten by people.

So, is Zhu Guotai's money exposed?
When I met Zhu Yantao in Rudong City before, the fat old man's smile was very healing. For such a gentle person, his son is not far behind. Besides, Fang Yue can choose, so he naturally has an excellent side.

Owning a chain restaurant, this financial resources in the Qindao area in 2004 is not that kind of top rich man, it can only be said that he is in the front position among the younger generation, and he has the most resistance injuries and abuse injuries, and even his intestines have been pulled Breaking a few meters, this kind of practice has been seen in the training of the small black room, and it is usually done when seeking revenge.

But what kind of enmity can a restaurant owner have with others?
Especially that child, whose lower body was pierced, even stirred up a bit, and there were multiple fractures on his body, which were injuries caused by the beating. What kind of cold-blooded person would do this to a child?
After getting the ransom, he didn't release them, and even killed the hostages while getting the ransom. Fang Yue took relative care. Could it be Fang Yue's former suitor, or someone he once knew well?

Zhou Ning shook his head, doubting too much, it seems that he still has to wait for Xu Dayuan and the others to sort out the information, and then investigate the social relationship between Fang Yue and Zhu Guotai.

15:14
Bureau Sun arrived in a hurry, and started yelling loudly as soon as he went upstairs.

"I said you didn't send anyone to wait for me downstairs. It's okay. It's my first time to come to your technical department. What's your opinion on me?"

"Bureau Sun is here, come in!"

Xu Dayuan hurried over. When the two shook hands, they slapped each other's arms vigorously. Zhou Ning was about to step forward, so he stopped quickly. He couldn't bear this greeting.

However, Bureau Sun saw Zhou Ning with an excited smile on his face.

"You can't be called Zhou Xiaozhou anymore. You are Director Zhou now. I said you must be a great talent. Look at this and you are going to follow what I said. But you are all so good, and I have a good eye for people."

As they said that, several people laughed. He Chunyang opened the door and came in at this moment, followed by two people with nervous expressions on their faces. He Chunyang nodded towards Xu Dayuan without too much enthusiasm.

"Boss Xu, someone brought it here. This is Cheng Zhi, the owner of Qidong Caiyun Fireworks Wholesale Department. He is the largest fireworks dealer in Qidong. This is his son Cheng Xinghui."

Xu Dayuan nodded with a smile, and shook hands with Cheng Zhi. The kid looked about 172cm tall and looked very mature, but his eyes looked like a child. Seeing so many policemen, he blinked nervously.

"Thank you for your cooperation, so how about we go to the next room to chat? The child will play here for a while, and I will ask the doctor to send him an individual. You can rest assured that this place is absolutely safe. Whether it was 12 years ago or now, the duty of the police is to protect The personal and property safety of the people.”

Cheng Zhi thought for a while and nodded. After all, they all chose to come and made up their minds.

"Actually, it doesn't matter if it's money or not. I just hope that my son will be healthy and safe. After all, this kid is hard-won. His mother almost died when he was born. We all treat him like a fool."

Director Sun patted Cheng Zhi on the shoulder and sighed.

"Don't talk about it, buddy. We all know who is not a parent. To avoid future troubles for the time being, let's go and talk together. Director Zhou's child will be handed over to you."

Zhou Ning nodded, those people all went out, Cheng Xinghui became more nervous, Zhou Ning didn't move, and winked at Xiao Qu, Xiao Qu was already prepared, and clicked on an interface of the phone.

Bang, a celebration interface popped up, and he wiped the sweat off his forehead in a serious manner.

"It scared me to death. The leader just came. If he saw me playing games for a while, wouldn't he scold me to death?"

Cheng Xinghui's attention was instantly attracted, and he looked at Xiaoqu with admiration on his face, and Xiaoqu made a boo gesture to Cheng Xinghui.

"Don't tell them!"

Cheng Xinghui nodded vigorously without leaving Xiaoqu's phone screen. Xiaoqu moved towards Cheng Xinghui unintentionally, and started another round of confrontation. After a few minutes, Cheng Xinghui relaxed. Seeing Xiaoqu's victory again, he turned towards Xiaoqu. give a thumbs up.

"Uncle policeman, you are really good. I also drove the purple diamond, but I can't get up!"

Xiao Qu waved his hand, and Da Zhao moved over.

"Don't call him Uncle Policeman. He's not a policeman, but a tentacle monster. He's an ashes of a computer professional. Let alone small games, hacking into other people's computers is a piece of cake for him."

Cheng Xinghui looked surprised.

"Uncle policeman, you are a hacker!"
