After the security guard left, Nianmu took out the box, took out all the utensils and started installing them.

She is familiar with these things and she doesn't take much time to assemble all the equipment.

After assembly, Nianmu took out the skin care products she brought back from Zhang Yali's villa. She corrected the brands one by one and found that only two of them were not found.

She decided to start researching with these two brands.

Nianmu ate the bread he bought on the way casually and began ingredient analysis.

Ingredient analysis is not a difficult task, but it takes a lot of time to analyze it. Until midnight, she finally got the ingredient analysis tables for two cosmetics.

One of the essences, the raw materials are basically bleach, alcohol mixture, and an unknown chemical.

Nian Mu frowned. Except for the unknown chemicals, other raw materials were very cheap. How could Zhang Yali use them?

She looked at the ingredients list and instantly realized that this essence is very harmful to the skin, but it is the kind of effect that can make people see after using it once, but it is caused by these irritating chemicals that damage the surface of the skin.

Nian Mu estimated that Zhang Yali would definitely not joke about her skin. Maybe she didn't know that the ingredients in it were bewildered by its effects.

She looked at another chemical substance and took another look at the time.

It was already three o'clock in the morning.

After thinking about it, she continued to extract this chemical substance to see if she could find out.

Until the morning, she still couldn't find out what kind of chemical substance was. Nianmu wrote down the combination of chemical substances and recorded it by the way.

Then he yawned back to the company.

Lei Zhong happened to be on the elevator with her. Seeing her depressed look, he said carelessly: "Professor Nian, did you not have a rest last night?"

Nian Mu touched his face, "Is it so obvious?"

"You are in poor spirits, yes, and have dark circles." Lei Zhong reminded.

Nian Mu smiled helplessly. She realized that when she was about to go to work, she had no time to put on makeup. She just hurriedly washed up and left the apartment.

Even breakfast was eaten while walking on the road.

Perhaps the other party was Mu Shaoling's mother, so she was like this. She stayed up all night and had to analyze these ingredients.

Only Mu Shaoling would make her so willing.

Nian Mu looked at Lei Zhong and asked, "By the way, I'll show you a piece of information, please help me see if I recognize this chemical substance."

She took out a piece of paper from the official document bag and handed it to Lei Zhong.

Lei Zhong took it and just as he was about to see it, the elevator arrived at the floor. Seeing that he didn't realize he was going to get off the elevator, Nian Mu grabbed his sleeve and reminded him: "I'll get off the elevator."

Lei Zhong came to his senses and quickly said, "Oh, OK."

The two left the elevator and did not notice someone in the corner of the elevator taking a cell phone to take a picture at them.

Nian Mu looked at Lei Zhong and asked, "Do you know this chemical combination?"

"I think it looks familiar. It seems that it is a research topic that my university tutor is doing, and it involves a similar combination element." Lei Zhong recalled with a frown.

Nian Mu asked, "Then do you remember the research topic about this type of substance, is it good or bad?"

"I remember it's bad, it has a certain impact on the human body, so try to touch it as little as possible. But I'm not sure, Professor Nian, where did you know about this kind of substance?" Lei Zhong asked. They usually don't touch these chemical substances, so it's normal for her to not know.

"I want to understand clearly what's going on in a skin care product. Can you help me?" Nian Mu asked.

"Of course, I'll ask the professor now." Lei Zhong agreed immediately, and took his mobile phone to take pictures of the arrangement on the paper.

Nian Mu nodded.

She returned to the office, put the things in place first, and then called Dong Zijun to an insider, "Assistant Dong, is Mr. Mu in the office now?"

"Here, Professor Nian, do you want to meet Mr. Mu?" Dong Zijun asked.

"Yes, I have some things to report here, about Ms. Zhang." Nian Mu said.

"Wait a minute, I'll go and send a message." Dong Zijun replied, put the phone aside and left the special assistant office.

Nianmu listened to the sound of his footsteps getting farther and farther away, so he waited patiently.

After a while, Dong Zijun came back, picked up the microphone, and said to Nian Mu on the other end of the phone: "Professor Nian, Mr. Mu asked you to come up now."

"Okay, I'll go up right away." Nian Mu said, picking up the information and going to the top floor.

When passing by Dong Zijun's office, she asked, "Assistant Dong, do you need a message?"

"No, the boss is waiting for you inside, just knock on the door and go in." Dong Zijun said with a smile.

Nian Mu nodded, walked to Mu Shaoling's office door, and knocked on the door.

"Come in." A low voice came from inside.

Nian Mu pushed open the office door and watched Mu Shaoling sitting in the chair of the senior class, processing documents. Her focused appearance made her unable to bear to disturb her.

On a night many years ago, Mu Shaoling would always take her work home in order to accompany her as much as possible.

At that time, I could not bear to disturb him when I saw him working hard.

"Mr. Mu, I have something to report to you." The moment Mu Shaoling looked up and looked at her, Nian Mu immediately returned to normal and looked at her.

"Come in and talk." Mu Shaoling pointed to the opposite position.

Nian Mu walked in and did not close the office door. After all, with Dong Zijun here, not everyone could come in.

And opening the door is also a way to prove your innocence.

Nian Mu sat on the chair opposite him, took out all the documents and placed them in front of Mu Shaoling.

"Yesterday I screened those skin care products and found two more suspicious brands. After comparing and analyzing the ingredients, one of them had problems," she said.

Mu Shaoling didn't say anything, picked up the information she gave to look at it.

Although he didn't understand these, he could tell what was going on when he saw the ingredient analysis.

"This ingredient comes from a bottle of the essence of the brand. The ingredient inside is very irritating to the skin, but it can quickly see the results. But this is the effect of bleach, without any real effect." Nian Mu explained.

"Will she use such a stimulating ingredient?" Mu Shaoling knew how much his mother had in love with beauty.

This essence should be very irritating when used on the skin, and she will not use it at will.

"Yes, but there is an unknown chemical substance inside. I don't know much about this, so I have asked someone to check it out. Perhaps it is this substance that can prevent the skin from being stimulated by other chemical components, so that people don't feel uncomfortable when using it." Nian Mu explained.
