Zhao Yu didn't expect that the forensic doctors in charge of the autopsy would be able to come up with a way to arrest the murderer.

"Team Leader Zhao," Gao Facai couldn't hide his excitement on the phone, "If our inference is correct, and this murderer is still studying his perfect corpse......!" We think that he will definitely find a way to improve the formula of the antiseptic solution and increase its stability.

"Therefore, we just restored the chemical structure of the three formulas, and then agreed that if the murderer wants to increase the stability of the formula, he needs to add antioxidant compounds, ethylene chelating agents or resin material stabilizers, etc., so that the erosion of the antiseptic liquid can be inhibited and the most perfect effect can be achieved!"

"Oh......" Zhao Yu mumbled, but he didn't understand it at all.

"You know what? If the recipe works, the corpse he makes will look like ...... However, the resin doll is a toy, but what he makes is ......."

Hearing this, Zhao Yu couldn't help but have his hair standing on end, and his back was cold!

"But...... That's not the point I'm going to talk about!" Gao Facai continued, "No matter which material the murderer chooses in the end, but when the antiseptic liquid reacts, an inducer called acyanenamine must be added......

Next, Gao Facai said a few words in English, and also said a lot of obscure chemical equations, and finally entered the topic after speaking:

"It was one of my students who reminded me that acyanenamine is something that requires large equipment to refine, and it is impossible for an individual to refine it. And because of the low price and very few applications, the output is very low. In the country, there are only a handful of producers.

"Generally speaking, there are only two ways to apply this kind of thing, one is in military scientific research, and the other is in chemical experiments in colleges and universities!

"We have checked, and this kind of thing is not sold on the Internet! If there is a private company that wants to buy it, then it can only place an order directly with the manufacturer!" Gao Facai said excitedly, "So, as long as we find out who has bought this kind of thing, it is possible to find the murderer!"

"Wow! This is amazing!?Okay! I'm going to check! I'm going to check......" Finally found a way, Zhao Yu was naturally more excited, and quickly asked again, "Tell me again, what is the name of that thing you said?"

Putting down the phone, Zhao Yu immediately told the team members about it! However, the reaction of the team members was not as Zhao Yu thought, Cui Lizhu was the first to stand up and deny:

"Boss, don't forget, my uncle is a professional thief, if he knows that he may be exposed when he buys something, he can steal it!

"That'...... Then let the manufacturer check carefully to see if this material has been stolen!" Zhao Yu said without discouragement, "Now that technology is so developed, I don't believe that he stole something, and he can still leave no traces!"

"I think this method is feasible!" Wu Xiumin nodded approvingly and said, "The head was only recently discovered! It is impossible for the murderer to know, and we police can guess his intentions based on this! He can buy it with a swagger, and he can't take the risk of stealing!"

"No matter what!give it a try!" Zhao Yu said to Zeng Ke firmly, "Zeng Ke, hurry up!"

"Okay!" In fact, when Zeng Ke agreed, his hands were already tapping on the keyboard quickly. After a while, he inquired about the manufacturer's information.

"Forensic doctor Gao is right, there are no more than 10 companies in the country that have equipment for the production of acyanenamine, and ...... It seems that there are still a few companies that have never produced at all......" With the continuous keystrokes, Zeng Ke quickly got a definite information, "Great, fortunately, these manufacturers are all large state-owned enterprises, and they have not closed down." In this case, except for those who have not produced and have just built a factory, I will ...... There are only two of them!"

"Great!" Zhao Yu clapped his hands and said, "You quickly ask the local police to contact the manufacturer, immediately go to inquire about the order information, and see who has bought it over the years?"

"Okay, but ......" Zeng Ke said, "Let's let Brother Tao and Sister Wu call, I'll try to get through the manufacturer's firewall and see if I can find the order directly!"

"Awesome!" Zhao Yu stretched out his thumb, then nodded at Wu Xiumin and Ran Tao, and the two quickly contacted the local police.

Zeng Ke is worthy of being a master hacker, and in less than ten minutes, he hacked into the network systems of both factories. Subsequently, orders from both factories were also found by him. After some screening and filtering, all the information of buyers who have purchased cyanenamine is displayed on the computer screen.

However, what everyone didn't expect was that there were not a few units that had purchased this chemical reagent. Even if the relevant military enterprises can be removed, they can be printed, and they still have more than 100 pages!

There was no way, everyone could only spread it out, and one person took a pile and began to manually filter and filter.

Zhao Yu looked at it carefully, but saw that the purchase information was all the words of the Cultural and Educational Bureau, XX Cultural and Educational Bureau, XX Cultural and Educational Bureau, and the like.

It seems that what Gao Facai said is right, except for the military industry, the people who buy this kind of chemical reagent are all colleges and universities! Not to mention individual purchases, there is not even a different kind of unit!

On the order form, in addition to the so-and-so Culture and Education Bureau, there are occasional words of so-and-so schools, but these schools are all large-scale universities and universities!

After seeing this information, Wu Xiumin was the first to raise his worries: "Team leader, it's broken! You see, so many schools have this kind of thing, if Li Fei steals not factories, but these schools, won't it be over?"

Who knows, after Wu Xiumin's voice settled, Zhao Yu was not disappointed, but jumped up like frightened!

"Hey, what's the situation, what is this?" Wu Xiumin ......was startled, and when she opened her mouth to ask, Zhao Yu had already rushed to Zeng Ke.

"Zeng Ke, hurry up, search for the information related to Bailing on the order form!

"Ahh......h

08 years?

"Grandma is a bear, Captain Sun! Hurry up and call Lao Sun and call him over!" Seeing that Zhao Yudu scolded the street, Zeng Ke hurriedly called Captain Sun.

Who knows, Captain Sun hasn't come over yet, but Gao Facai walked in first.

"Team Leader Zhao, how is the information?" Gao Facai asked and said, "I forgot to make it clear to you just now, although acyanenamine is an inducer, it needs to be purified because of its special properties. Therefore, the murderer needs to buy a large amount of goods, and he can't steal one or two bags to solve the problem!"

"Oh......" Zhao Yu nodded, it seems that Li Fei's possibility of stealing things is not very big.

"Team Leader Zhao, are you looking for me?" Captain Sun received the order and rushed over.

As soon as Zhao Yu saw Captain Sun, he hurriedly said, "Old Sun, you immediately ask your people to contact the Bailing Cultural and Education Bureau to check the purchase situation of what kind of rare goods, and see which school they are assigned to?"

"What...... What does it mean?" Captain Sun naturally couldn't understand.

"Cyanidelamine!"

Under Gao Facai's simple explanation, Captain Sun understood the whole story. Realizing that the matter was important, he called the director of the Culture and Education Bureau on the spot.

It didn't take long for the Bureau of Culture and Education to send back the information, saying that their Finance and Planning Department had verified that 08 was the completion of the reconstruction of the chemical laboratory building of Bailing No. 1 Middle School, so the batch of chemical preparations and instruments and equipment purchased were all sent to Bailing No. 1 Middle School!

OMG!

After getting this news, Zhao Yu's heart couldn't help but pound! He finally understood that yesterday's seemingly bloody copy adventure might not be a coincidence encountered in vain!
