It's really a bright village! Zhao Yu never expected that the forensic doctors in charge of autopsy would 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 the murderer is still studying his perfect body! Then... we think that he will definitely find a way to improve the formula of the antiseptic liquid and increase its stability.

"So, 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-type stabilizers, etc., so that the corrosion effect of the anticorrosion liquid can be suppressed and the most perfect effect can be achieved!"

"Oh..." Zhao Yu said ummy, but she couldn't understand at all.

"Do you know? If the formula is successful, the corpse he made will look like... a resin doll! However, the resin doll is a toy, but what he made is..."

Hearing this, Zhao Yu couldn't help but stand upright and her back felt cold!

"But... this is not the point I want to say!" Gao Facai continued, "No matter which material the murderer chose in the end, when the anticorrosion liquid reacts, an inducer called cyanocyanamine must be added..."

Next, Gao Facai said a few words in English and also said a lot of obscure chemical equations. After that, he finally got to the topic:

"It was one of my students who reminded me that things like acyanine need large equipment to extract, and individuals cannot refine them. Because of their low price and very few applications, the output is extremely low. There are only a handful of production companies in the country.

"There are generally only two ways of application, one is military scientific research, and the other is chemical experiments in universities! The use rate among the people is basically zero.

"We have checked that this kind of thing is not sold online! If a private company wants to buy it, then you can only place an order directly with the manufacturer!" Gao Facai said excitedly, "So, as long as you find who bought this kind of thing, you may find the murderer!"

"Wow! So amazing! OK! I'll check it now! Check it now..." After finally finding a solution, Zhao Yu was naturally even more excited and asked again, "Tell me again, what is the name of the thing you are talking about?"

After putting down the phone, Zhao Yu immediately told the team members about this! However, the team members' reaction was not as Zhao Yu thought. Cui Lizhu was the first to stand up and deny:

"Boss, don't forget that my master is a professional thief. If he knows that buying things may be exposed, he can steal it! It's just a factory, isn't it a piece of cake?"

"Then... let the manufacturer check carefully to see if this material has been stolen!" Zhao Yu said without discouragement, "Now that technology is so advanced, I don't believe that he can steal things without leaving any traces!"

"I think this method is feasible!" Wu Xiumin nodded in approval and said, "The head was discovered recently! The murderer could not know at all. Our police could guess his intention based on this! He could buy it with a swagger, and he would not risk stealing!"

"No matter what, you have to 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 typing on the keyboard quickly. After a while, he searched the manufacturer's information.

"The high forensic doctor is right. There are only 10 companies in the country that have produced cyanide amine equipment, and... it seems that there are still several companies that have not produced them at all..." With the continuous keyboard typing, Zeng Ke quickly obtained a precise information, "Great, fortunately, these manufacturers are all large state-owned enterprises and have not gone bankrupt. In this case, except for the fact that there is no production, it is still the one that has just built the factory. I will... only two companies!"

"That's great!" Zhao Yu clapped his hands and said, "You can ask the local police to contact the manufacturer immediately to check the order information of that rare thing, and see who has bought it over the years?"

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

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

He once deserved to be a master of hacking. In less than ten minutes, he invaded the network systems of both factories. Then, he found orders from both factories. After some screening and filtering, all the buyer information of those who had purchased cyanocyanide were revealed on the computer screen.

However, what everyone did not expect was that there were quite a few units that had purchased this kind of chemical reagent. Even if the relevant military enterprises could be removed and printed out, it would still look like more than a hundred pages!

There was no choice but to spread it apart, each of them took a stack and started manual screening and filtering.

Zhao Yu looked carefully, but found that the purchase information was full of the words of the Cultural and Education Bureau, xx Cultural and Education Bureau, xx Cultural and Education Bureau, etc.

It seems that Gao Facai is right. In addition to military industry, those who buy this kind of chemical reagent are all colleges and universities! Not to mention individual purchases, there is not even a different unit!

On the order form, in addition to the Cultural and Education Bureau, the words "Xi" school sometimes appear, but these schools are all larger universities!

After seeing this information, Wu Xiumin was the first to raise his concern: "Team leader, it's broken! Look, so many schools have such things. If Li Fei stole not the factories, but these schools, wouldn't that be done?"

Unexpectedly, after Wu Xiumin finished speaking, Zhao Yu was not disappointed, but instead jumped up like scared!

"Hey? What's the situation? This is? Team leader..." Wu Xiumin was startled. When she asked, Zhao Yu had already rushed to Zeng Ke.

"Zeng Ke, hurry up and search for information related to Bailing on the order! Especially Bailing No. 1 Middle School!"

"Ah? Oh..." Zeng Ke didn't know why Zhao Yu was excited, but he still did as Zhao Yu's instructions. "I found out that some were some, and the Bailing Municipal Bureau of Culture and Education purchased a batch of goods in 2008!"

2008?

"Grandma, Captain Sun! Call Lao Sun quickly and call him over! Hurry!" Seeing that Zhao Yu was scolding and opening the street, Zeng Ke quickly called Captain Sun.

Unexpectedly, before Captain Sun came over, Gao Facai walked in first.

"Team leader Zhao, how did the information be checked?" Gao Facai asked and said, "I forgot to explain it to you just now. Although acetylene amine is an inducer, it needs to be purified because of its special attributes. Therefore, the murderer needs to purchase a large amount of goods, and it is not possible to solve the problem by stealing one or two bags!"

"Oh..." Zhao Yu nodded. It seemed that Li Fei might not have been stealing very much.

"Captain Zhao, are you looking for me?" Captain Sun rushed over with great enthusiasm after receiving the order.

When Zhao Yu saw Captain Sun, he hurriedly said, "Old Sun, please contact your people immediately to Bailing Culture and Education Bureau to check the purchase situation of that rare product, and see which school they all allocated to?"

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

"Acylcyanamine!"

After Gao Facai's brief explanation, Captain Sun understood the whole story. Realizing that the matter was of great importance, he called the director of the Culture and Education Bureau on the spot.

Not long after, the Culture and Education Bureau sent back the information, saying that their Finance and Finance Department had verified that the renovation of the Chemical Experimental Building of Bailing No. 1 Middle School was completed in 2008, so the batch of chemical preparations and instruments purchased were all sent to Bailing No. 1 Middle School!

Oh my god!
Chapter completed!
