After the Group Pet, the Ancestor’s Vest Went Crazy

"Oh?" The mayor also raised his eyebrows, curious.

Yun Ling moved a chair and said, "Sit down, I will talk to you about this slowly."

"Okay!" The mayor suddenly became interested and sat on the chair. The rest of the people, including Qin Yanxi, turned their attention to Yun Ling.

Yun Ling smiled. Originally, she only wanted to solve this problem within the school, but Yin Mengqiao got together, so don't blame her for having a black belly.

"That's it. Before our chorus came to the stage, six students were allergic to lips. Originally, Teacher Bai and I thought it was an accident. After our investigation, we discovered that someone deliberately put an excessive amount in this lip glaze. benzoic acid!"

After all, Yun Ling took out an Armani 402 lip glaze from the pocket of his school uniform.

When he saw this lip glaze, Wen Shiyang pulled Yin Mengqiao excitedly.

Yin Mengqiao glared at her, gave her a hard push, signaled her not to make a fuss, and calm down!

She had expected it a long time ago, what should be done in case of Dongchuang incident? So prepared in advance.

So at this moment, Yin Mengqiao didn't panic at all when seeing the'murder weapon' found, but sneered.

She wants to see how the hillbilly solves the case!

Watching Conan comics all the time, do you really think you are a detective?

"Mr. Mayor can smell it."

Yun Ling unscrewed the lid of the lip glaze and handed it to the mayor's nose.

The mayor sniffed and frowned: "There is indeed something pungent and spicy to the eyes."

After he finished sniffing, he handed the lip glaze to Qin Yanxi: "You should also smell it, and decide the case together."

The principal took the lip glaze and sniffed, frowning.

Qin Yanxi's reaction was exactly the same. Both of them smelled a strong, formaldehyde-like smell in it. The language could not describe the specific smell, but it was pungent and spicy.

The city committee of other inspection teams also smelled it, and their expressions were almost the same.

"I have this lip glaze, it's definitely not the smell." A young city party committee said.

The mayor nodded: "Find a chemistry teacher and test the substance inside."

"You don't need to find a chemistry teacher, isn't Xueba just here?" Yun Ling raised his head in an air, and turned his eyes to Qin Yanyue in the corner.

Upon seeing this, Bai Yanran immediately echoed: "Yes, yes, this child Yanyue often soaks in the chemistry laboratory. His experimental level is among the best in the country, and he has won many first prizes."

The mayor heard the words and nodded: "Well, let's all move to the laboratory."

"Prior to this, the principal, I beg you to ask the security room to adjust this, as well as the monitoring of the chemical experiment." Yun Ling raised his hand and pointed to the electronic eye in the corner.

The principal immediately nodded, and he didn't even notice that he obeyed Yun Ling's words like this.

-

The school auditorium is only five minutes away from the chemical laboratory.

Five minutes later, a group of people Wuyang Wuyang stood in the aisle.

There are important equipment in the laboratory, and there are potential safety hazards in doing experiments, so irrelevant people are not allowed in, and everyone can only stand on the outside of the glass window.

In the laboratory, there are only Qin Yanyue, the mayor, the principal, and Qin Yanxi and Yun Ling.

"Let's use a liquid chromatograph for detection." Qin Yanyue briefly introduced her own detection methods and steps, and then began to immerse himself in the operation.

He took a sample carefully first, then added it to the test tube, poured the three solutions in succession, made the volume constant, vortexed, and took out the filtrate...

Soon, pour the filtrate into the testing instrument.

"Look at the test results. This lip glaze contains 5% benzoic acid. How much can the content of normal cosmetics not exceed?"

In the first sentence, Qin Yanyue said it to others. In the latter sentence, she raised her eyes and turned to Yun Ling to ask her.

Yun Ling checked it with his mobile phone: "Normally, it does not exceed 0.1%. This lipstick exceeds the normal value by 50 times!

Of course, someone will come out to argue later, saying that it may be the production responsibility of the Armani manufacturer, so let's look at the monitoring! "

"Mr. Mayor, then move my office, the security captain has already called out the monitoring."

So the group moved in mighty force from the chemical laboratory to the principal's office.

The office is very large, so nearly 40 people squeezed in. A group of people gathered in black and surrounded in front of the principal's computer.

Where did the security captain have seen such a big battle?

He had some stage fright, plugged in the U disk, turned on the monitor, and his hands kept shaking during the whole process.

The one who formed a sharp contrast with him was Yun Ling, who stood by and commanded, not chaos in the face of danger: "Go forward, between 6 and 9 in the morning."

"Good." The security captain rewinded as instructed.

"Stop!" The speed is very fast due to the quadruple speed. If you don't look closely at the screen, you won't be able to see it at all.

The security captain stopped, and Yun Ling pulled forward again.

When she saw that there were obvious traces of deletion in the surveillance, she sneered: "From 7:23 to 25 in the morning, two minutes of surveillance were deleted in the middle.

If I'm not mistaken, the monitoring of the chemical laboratory is probably also deleted. "

"Deleted? Isn't it? Wouldn't it be impossible to catch the murderer?"

"This murderer is so cunning! Actually knows to delete surveillance? Is this a habitual offender?"

"Thinking about it is terrible, there is such a villain in Lawrence College? This time it is lip glaze and excessive benzoic acid. Next time, maybe poisoning!"

"Yes, yeah, this kind of person is too dangerous!"

The students chatted and talked a lot, all expressing fear.

The mayor furrowed his brows and glanced at Qin Yanxi and the principal: "It seems that your school's education is not perfect. We must pay attention to the students' ideological and moral education."

Upon hearing this, the principal turned pale.

He really wanted to call Yun Ling a little ancestor!

As the saying goes, family ugliness should not be publicized. There are bad elements inside the school. It is not enough to deal with it behind closed doors. Why should there be a big trouble?

Now that's all right, the mayor criticized him.

"Mr. Mayor, the top priority now is not to blame the school, but to catch the murderer. Our country is safe and secure, and the rule of law is strict, but there are still gangsters. Individual bad incidents, please do not rise to the collective.

This little wicked mind is broken. No matter how the school teaches him ideological and moral classes, his wicked mind will not be cleaned up. This kind of person has a good place to go. "

Yunling paused, dragging a long tail.

"Where?" The principal hurriedly took the question.

"Youth control office." Yun Ling hooked the corner of his mouth and smiled wickedly.

Yin Mengqiao's heart stunned when he heard the words.

At this moment, someone in the crowd said: "I remember! I went through the chemical laboratory the day before yesterday and found Yin Mengqiao sneaking out of it. Could it be that she was the murderer?"

Hearing someone pointed the finger at him, Yin Mengqiao became anxious: "Funny! Qin Yanyue goes to the chemical laboratory all day long, why don't you say that he is the murderer? You have no evidence, so don't spit people with blood!"

"How could it be Brother Yue? Brother Yue has no conflict with us, but you, maybe we didn't choose you as the lead singer, do you hold a grudge?" Yu Minmin immediately retorted.

Suddenly, the two of them quarreled, and the volume was loud.

"I am a dancer, what good is it for me to frame your chorus? Our show is one! Squad leader, I know you have always been biased against me. After all, we have been fighting for the title of class flower for two or three years, but you You can’t just pour dirty water on me just because of personal enmity, right? You are like this, without the fairness of the squad leader."

"You..." Yu Minmin died of anger, but was unable to refute.

There is no evidence, even if they all think that Yin Mengqiao did the bad thing, that's all right!

At this moment, Yin Mengqiao kept pretending to be pitiful, which made her feel wronged.

"Stop fighting, do you want evidence? I'll do it." Yun Ling couldn't stand it anymore, and she also felt that Yin Mengqiao did this.

She patted the security captain on the shoulder: "Uncle, please let me know, I have a way."
