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

"What's the matter? Did you eat something bad?" Bai Yanran walked over and checked the girls' mouths one by one.

"Students who have a sore mouth gather here. The teacher will write down their names, and then you can go to the infirmary and find a doctor to prescribe some medicine."

There are six classmates with sore mouths, five girls and one boy.

Among the six, some of them were more squeamish, and they all cried out in pain.

"Mr. Bai, will this affect the chorus later? After all, we are the first to be on stage, and there are only 20 minutes left before we are on stage."

"Yes, it takes ten minutes to go to the infirmary here, plus the time for the doctor to see the doctor and prescribe the medicine, it's a bit rushed."

"Teacher Bai, they come running out of breath, which will greatly affect the state of performing on stage." Yu Minmin walked to Bai Yanran's side, as the class leader, wanting to share some responsibilities for the teacher.

But at the moment, neither of them can think of a better way.

While they were discussing what to do, Yun Ling strode towards the dressing table, opened the bottles and cans that the classmates had used, and smelled them.

At first, her expression was calm.

Until she grabbed an Armani 402 lip glaze and unscrewed the lid, her brows came together naturally.

"No need to go to the infirmary, go to the infirmary to waste time, toss back and forth and still have a mentality."

Yun Ling took the entire lip glaze in his hand, turned around, and inspected the people in the room: "Whoever used this lip glaze just now, raise his hand."

"I."

"And I."

"we."

"Me and Dongzi."

Six people raised their hands, just the six who yelled that their mouth hurts.

When the students saw that the fat Dongzi also raised his hand, they couldn't help holding back a smile.

"Little fat, you old man, what kind of lip glaze should I put on! It just happened to be this color number!"

"Hahaha, our chubby has a girlish heart."

"En?" Yun Ling raised his eyebrows, staring sharply at a few classmates who were joking.

These melons are really inadequate, and they don't look at the current situation or the occasion.

Yun Ling's eyes were extremely killing, cold and cool, her aura at this moment far surpassed Bai Yanran.

The joking classmates closed their mouths in an instant, and lowered their heads one by one, realizing their own mistakes, and being honest in an instant.

Yun Ling saw that these children finally stopped making noisy, and then continued: "This lip glaze has been added with allergenic drugs, so these students who have applied this lip glaze will have allergic reactions. ."

"Ah? It's artificial? Who is so terrible!"

"Does this count as poison? Is it illegal?"

The classmates looked at each other, thinking about it with extreme fear, shouldn't they, have their hands and feet been touched in other cosmetics?

"The crime is not serious, it is not that serious, but he must have violated the school rules, as long as he can be caught, warned or expelled, it is possible."

Qin Yanyue, who had not had any sense of participation, strode forward, drew her pockets with both hands, came to Yun Ling's side, and stood shoulder to shoulder with her.

He is a high school student and the person in the class who knows the most about law. His classmates believe in what he said.

"What should we do? We don't know who the murderer is now?"

"Yes, what should I do?"

"Everyone doesn't panic. If you have mouth allergies, go find a piece of soap and get some soapy water to clean your lips. This sensitizer is acidic. Just neutralize the acid and alkali, and then rinse with clean water. Min, you take them to the bathroom.

Other students, we all use Teacher Bai's lipstick, first touch the finger, and then apply it to the lips.

Okay, everyone move! "

Yun Ling clapped his hands, calm and wise.

Everyone got orderly under her instructions.

"Brother Yun, how can you be so calm and calm?"

After the students did their own things, Qin Yanyue looked at Yun Ling and asked her curiously.

Yun Ling put the Armani 402 lip glaze into his trouser pocket, and continued to search around, looking for clues that the murderer might leave.

Hearing Qin Yanyue's question, she didn't look up, and spoke naturally: "It's not a big deal."

A few classmates had mouth allergies. In her opinion, it was just a little trouble.

However, don't do something small for good, and do not do something small for evil.

Although this matter is small, she also has to find out, and show the classmates a fairness!

In this section, the sensitizer is placed in the lip glaze that the students use for makeup, which obviously wants to affect the performance of their chorus.

"Brother Six, you smell it."

Yun Ling rummaged around, but found nothing useful, so he turned his attention back to the'murder weapon'.

She took out the lip glaze, unscrewed it and handed it to Qin Yanyue.

Qin Yanyue sniffed, and frowned like Yun Ling's reaction just now: "Benzoic acid?"

"Yes." Yun Ling nodded: "Brother Six, you should know how to extract this stuff, right?"

"The school's chemistry laboratory?" Qin Yanyue frowned, "But I haven't passed this week."

"It's okay, there is it." Yun Ling lifted his head and fixed his eyes on the monitor in the corner of the room. The murderer was bold, but forgot that the school was full of electronic eyes!

"When will the murderer be caught?" Qin Yanyue asked: "I know the chemistry laboratory. I will take you there when the time comes."

"Well, after the chorus is over."

-

A few minutes later, Yu Minmin returned to the dressing room with six students.

"Teacher Bai, Brother Yun, the classmates have washed their mouths clean, saying that their mouths no longer hurt or itchy!"

"Let me see." Bai Yanran checked the lips of the students one by one, and found that it was indeed not as red and swollen as before.

She was surprised and turned to look at Yun Ling: "What the **** is going on?"

"It's very simple. Some people inject a benzoic acid solution into the lip glaze. This solution is generally used as a preservative, but lipsticks and skin care products are prohibited from using this preservative. Like Armani lip glaze, there must be no such preservative. Benzoic acid.

Benzoic acid has a pungent, formaldehyde-like smell, which can be distinguished by smelling it. If this thing is too much, it will cause skin edema, rash, itching, peeling, etc. after touching the skin, which is the reaction of the six students just now. "

Bai Yanran was a mathematics teacher and had good chemistry grades back then, so after listening to Yun Ling's analysis, she immediately understood.

Other students can understand part of it as soon as they listen to it, and although they don't understand another part, they somehow feel that Yun Ling's remarks are noble.

Just the way that Brother Yun said that his head is Taoist, is he really a scumbag?

A group of classmates looked at each other and doubted life again.

"Teacher Bai, let's talk about the murderer. Let's get ready for this chorus. We must leave a good impression on the Lord Mayor?"

Yun Ling smiled and quickly brought the topic back to the right track.

The murderer wanted to hinder the normal performance of their chorus, ha ha, no way!
