In a word, everyone already knows who is calling, Sun Ju is now the head of the Qidong Branch, although he is not as outrageous as Xu Dayuan's promotion speed, but he is also a real leader.

Lao Liu seemed to think of something, his eyes lit up, and he came to Xu Dayuan's side, Xu Dayuan helplessly clicked on the hands-free, and the sound of turning pages and tapping on the keyboard in the room also stopped cooperatively.

"Didn't you let us cooperate? I thought about Cheng Zhi, the boss who He Chunyang went to find the fireworks, and it was not solemn enough, so I called him personally, and did you forget that I did this eucalyptus back then, why didn't you tell me directly? ”

Xu Dayuan smiled awkwardly.

"Hehe, how can I forget this, I don't think that if He Chunyang can do it, he won't trouble the old leader."

"Don't engage in these false things with me, you are now my leader, I will take Boss Cheng and the child over in a while, as for taking pictures to check your fingers, I think Zhou Xiaozhou can do it, or you can watch it yourself."

Xu Dayuan naturally has no opinion.

"Okay, but the kid has class today, right? Let's come together? ”

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

"Don't play with me, I told Boss Cheng that I met a eucalyptus, which was very similar to his son's kidnapping, after police analysis, that young man is not like the real murderer, the real murderer was not caught, and the possibility of retaliation is not impossible, after all, the ticket was torn up in the new eucalyptus."

"I've learned, it's still the old treacherous and cunning of the Sun Bureau, okay, I'm not polite to you, come and call me."

After speaking, Xu Dayuan hung up the phone quickly, and could vaguely hear the sound of Sun Ju's fried hair coming from the microphone.

Zhou Ning saw Xu Dayuan hang up the phone, so he pointed to the door.

"Since Ju Sun will be here in a while, then I'll go study the inspection report first, and when I see Ju Sun, and the survivor of the kidnapping, let's summarize it, right?"

Xu Dayuan did not object, a few people returned to the laboratory, Zhu Xingxing, they seemed to be looking at something, Zhou Ning walked over and asked subconsciously.

"Did you find anything?"

Zhu Xingxing looked up and saw Zhou Ning and them coming back, so he got up from the ground, but it seemed that he had been squatting for a long time, and his feet were numb, so he fell to the side together, and Da Zhao hurriedly supported her.

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

Zhu Xingxing glanced at him, struggled a little embarrassedly, thumped his legs and pointed to the test report and said:

"Look, you see, we rearranged the chemicals found on the clothes of these deceased, and 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 should be a special kind of grease, not for ordinary cars or boats.

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

Zhou Ning frowned slightly, this discovery, coupled 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 took a closer look, rarely with a serious expression.

"I'm going to ask my old man to see where these things are used and who can get their hands on them."

After saying that, Da Zhao walked away, in fact, Zhou Ning never asked about Da Zhao's family history, but Zhou Ning could also guess a thing or two, he grew up in the army since he was a child, and his parents were in the army, so he should be in some important positions.

After waiting for a long time, Da Zhao returned.

"My dad said that this solid grease is unique to them, and there are many people who can come into contact with it, mainly the personnel responsible for ship maintenance, and it is not of great use to take this thing back, so the control is not very strict.

However, this kind of oil has defects in high temperature resistance, and now it is more advanced, it is a newly developed oil, and the composition has changed greatly, and it is considered to be an obsolete product before 2003. ”

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

If the kidnapping of Qidong in 2000 was also committed by this person, then it is possible that this person had been a soldier and enlisted in the army before 2000, although the recruits had holidays, they could not come out, so they enlisted earlier, and even at this time they may have been discharged.

But what does he do with this grease?

Is it to maintain the knives?

Thinking of this, Zhou Ning took out his mobile phone and dialed Cui Lili's phone, but the other party answered in seconds.

"What's wrong?"

"Eldest sister, let me ask, just now Zhu Xingxing said that the oil on the deceased's clothes has analyzed a lot of chemical components, so I want to ask if a similar test has been done in the wound of the deceased, is there any same composition?"

"I just checked my work notes, and I did do a comparison in them, but it was sent by Cui Haibin Group at that time, although wound extracts were collected in it, but there was no prompt to compare chemical residues, so I didn't give them the corresponding report, and later I looked at the experimental process records, I think I should keep the bottom, find me and send 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 preserve 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 agreed with this analysis.

"It is indeed possible, but according to this analysis, the identity of this murderer may be a retired soldier, if this identity can be determined, then he can escape the arrest of the two kidnapping scenes on February 3, 2000 and April 14, 2004, it really makes sense."

Zhou Ning didn't speak, staring at the information sorted out on the glass whiteboard, looking carefully.

But his heart has already surged, if the murderer is really this identity, then the difficulty of this eucalyptus will 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 is born illegally, but Fang Yue is not very popular, and he can only get his hands on the films he participated in, if he was not killed, I am afraid that he would have been forgotten by people long ago.

So, is Zhu Guotai's money exposed?

When I saw Zhu Yantao in Rudong City before, the fat old man's smile was very healing, such a gentle person, his son was not far behind, and he could let Fang Yue choose, naturally he had an excellent side.

Owning a chain hotel, this financial strength in the Qindao area in 2004, is not the kind of top rich, can only be said to be the top position in the younger generation, and he has the most resistance injuries and abuse injuries on his body, and even his intestines have been torn off a few meters, this practice has been seen in the training of the small black house, and it is generally done in the case of seeking revenge.

But what kind of grudge can a person who opens a restaurant have with others?

Especially that child, his lower body was pierced, and even stirred, and there were multiple fractures on his body, which was an injury caused by a beating, what kind of cold-blooded person would do this to the child?

The ransom was obtained, and the people were not released, and even the hostages were tortured and killed while the ransom was obtained, and Fang Yue was relatively taken care of, could it be that Fang Yue was a former suitor, or someone he once knew?

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

......

15:14

Sun Ju came in a hurry, and began to shout as soon as he went upstairs with a loud voice.

"I said that you don't send anyone to wait for me downstairs, so I don't care, it's the first time I've come to your technical department, what is my opinion?"

"Sun Ju is here, come in!"

Xu Dayuan hurriedly walked over, and when the two shook hands, they slapped each other's arms hard, Zhou Ning was about to step forward, but quickly stopped, and said hello like this, his physique was a little unbearable.

However, Sun Ju saw Zhou Ning at a glance with an excited smile on his face.

"You can't be called Zhou Xiaozhou, you are Director Zhou now, I will say that you must be a great talent, look at what I said, but you are all so powerful, and I also have a vision for people."

Saying that, several people laughed, He Chunyang only pushed the door in at this time, with two people behind him, with a somewhat nervous look on his face, He Chunyang nodded towards Xu Dayuan, without too much enthusiasm.

"Xu Ju, someone brought it, this is the boss of Cheng Zhi Qidong's Caiyun Fireworks Wholesale Department, and 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, that kid looked about 172 tall and looked very mature, but his eyes looked like a child, and when he saw so many policemen, he kept blinking nervously.

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

Cheng Zhi thought about it and nodded, after all, he chose to come, and he also made up his mind.

"Actually, it doesn't matter if the money is not money, I just hope that my son can be healthy and safe, after all, this kid is not easy to come by, his mother almost gave birth to him, we all treat it as eyeballs."

Sun Ju patted Cheng Zhi's shoulder and sighed.

"Don't talk about this, man, we all understand, who is not a parent, don't you avoid future troubles for the time being, let's go and talk about it, Director Zhou's child is handed over to you."

Zhou Ning nodded, those people all went out, so Cheng Xinghui was even more nervous, Zhou Ning didn't move, and glanced at Xiaoqu, Xiaoqu had already prepared and clicked on an interface on the phone.

Bang, jumped out of a celebratory interface, and wiped the sweat from his forehead with care.

"But I'm scared to death, the leader just came, if you see me playing a game for a while, don't you scold me to death?"

Cheng Xinghui's attention was instantly attracted, and he looked at Xiaoqu with adoration on his face, and Xiaoqu made a shushing gesture towards Cheng Xinghui.

"Don't tell them!"

Cheng Xinghui hurriedly nodded vigorously, his eyes did not leave Xiaoqu's mobile phone screen, Xiaoqu moved towards Cheng Xinghui unintentionally, and began another confrontation, after a few minutes, Cheng Xinghui relaxed, saw Xiaoqu win again, and gave Xiaoqu a thumbs up.

"Uncle policeman, you are so good, I also opened a purple diamond, but I can't go up!"

Xiaoqu waved his hand, and Da Zhao leaned over.

"Don't call him a police uncle, he's not a policeman, he's a tentacle monster, a hardcore figure in the computer major, not to mention small games, it's hacking into someone else's computer or something, it's a piece of cake for him."

Cheng Xinghui looked surprised.

"Uncle policeman, you're a hacker!"
