There is no doubt that this night was extremely difficult for Liu Shang.

The stomach was filled with rivers and seas, and the fire was so hot that I almost vomited for a night.

In the end, Liu Shang simply moved a chair and stationed it in the corridor at the entrance of the bathroom.

In order not to worry Jiang Ruolin, he turned off his phone early and said he was going to bed.

Maybe it wasn't until dawn that he got better and lay down on the bed and fell asleep.

When he woke up the next day, the rest of the dormitory had already washed up and was about to go out.

With Liu Shang's current state, it was naturally impossible to go to work. So, after getting up and changing, he went directly to class with him.

Since he was still in a state of dry retching in the morning, he just drank some water and did not dare to eat.

After learning through text messages that Liu Shang went to class, Jiang Ruolin, who happened to have no class in the morning, took the morning and some stomach-nourishing medicine to find the classroom where Liu Shang and his class were located.

On the way, I happened to meet Zheng Jiao.

After getting angry with Tan Feng and Zhou Liang, Zheng Jiao, who returned to the dormitory, was still very angry.

The next morning, she withdrew seven thousand from her private money. No matter what, she got Liu Shang's card by herself last night, and she always had to return the money to others with her own hands.

So, the two of them came to the classroom door together and waited for the end of the class.

When the two of them came outside the classroom, the atmosphere in Liu Shang and his class was extremely depressing.

Due to Liu Shang's continuous absenteeism, he had already been blacklisted by several teachers.

Today, I happened to run into Li Wenzhong, the teacher who was the most dissatisfied with him, who was in charge of surfactant chemistry.

After a while in this class, Li Wenzhong finally couldn't bear it anymore and waited for the questioning session.

"Let me ask a question, what is surfactant micellation?"

"Liu Shang! Are you here?"

Then, under the laughter of other students in the classroom, Liu Shang slowly stood up.

At this time, Li Wenzhong on the podium looked at him and pointed.

"So you are Liu Shang? It's really rare to see your true face today!"

"I think you may have a big opinion on me, which leads to you not coming in my class."

"Or you can tell me all the content I teach, and it doesn't feel difficult?"

"Then please answer this question so that we can all see your true knowledge!"

As Li Wenzhong finished speaking, everyone in the classroom chuckled. Everyone who had good relationships with Liu Shang slapped their foreheads, waiting to see Liu Shang make a fool of himself.

In fact, their laughter is not malicious. I believe that any student who misses classes every day will be called by such a teacher and has a sense of joy.

Seeing this scene in the classroom and the loud and angry voice of Li Wenzhong obviously under his control, Jiang Ruolin outside the classroom door frowned, her eyes full of worry.

Seeing her like this, Zheng Jiao, who was beside him, sighed lightly.

"Ruolin, it's actually been a long time since Liu Shang didn't come to class, or to be more precise, he didn't take any class."

"I heard that many teachers now have a bad impression of him, and I'm afraid he will be very miserable in the final exam."

"If you have the chance, you should advise him. He may be excellent in his abilities, conversation, and other aspects."

"But if you fail the course often, cannot graduate normally, or even take a leave of absence, you two will definitely not be able to talk about any future."

"Actually, before yesterday, I thought you two were very inappropriate, and he would definitely not be worthy of you before."

"But after last night, I might understand why you chose him."

"I'm also very curious about how many years later, when college is about to end, what will happen to you two? Will it really come to the end?"

"So, if you have the chance, please advise him not to put the cart before the horse, not to be too ambitious, or lose his ambitions."

In fact, Zhou Liang, Tan Feng and others have known about Liu Shang's frequent absence from classes and the red lights have already been on with many teachers.

They were just waiting, and when the thunder gathered and became bigger and bigger, they were about to explode, they would go to Jiang Ruolin to cause a fatal blow to Liu Shang.

Due to his changes in his mind's impression of Liu Shang and his disgust towards Zhou Liang and others' despicable behavior, Zheng Jiao kindly burst the bubble in advance.

But to her surprise, after listening to her words, Jiang Ruolin kept shaking her head, "No, Liu Shang is definitely not the kind of person who is too ambitious and loses his ambition!"

Seeing her confident view of Liu Shang, Zheng Jiao shook his head incomprehensible.

"Ruolin, none of us are ostrichs, we can bury our heads in the sand."

"Some things and some problems will be faced sooner or later."

Just as they were talking, Liu Shang in the classroom smiled bitterly, and then to everyone's surprise, he really answered Li Wenzhong's question.

Perhaps because of the surprise and abrupt moment, the classroom became quieter and quieter. Li Wenzhong on the podium couldn't help but frown and directly raised the second question of some difficulty:

"Liu Shang, please answer again, what are the surfactant hydrophobic groups in the market?"

Without any hesitation, Liu Shang blurted out, "Are the hydrophobic group?"

"Natural fatty acids, petroleum paraffin, alkyl benzene, alkyl aromatic compounds, alkyl phenol, polyoxypropylene, silicone resin."

"Well, there are fluorocarbons, which should be counted."

Once again, beyond everyone's expectations, Liu Shang answered this question again fluently and accurately.

However, several academic masters in the classroom frowned slightly. What is the fluorocarbon compound that Liu Shang mentioned?

The teacher didn't mention it before?

Fluorocarbon surfactants are also a surfactant that has been widely used in a few years and ten years later.

Its effect on reducing surface tension is very prominent, but the effect is slightly worse in changing the oil-water interface tension.

Even the lecturer Li Wenzhong is not very familiar with this cutting-edge technology, so when he heard Liu Shang mention this, he was stunned.

"Ha, I have to say that your answer this time is very good. Maybe you read the book in advance before you came to class today."

"Next, I want to test you a calculation question and use the debye-huckel formula to calculate the activity coefficient of the surfactant solution."

Afterwards, Li Wenzhong waved his pen and wrote a very difficult question on the blackboard.

Don’t say you do it, even if you look at it, you will feel headache and dizzy.

If you want to do this problem, you must not only be very familiar with the relevant chemical formulas and theories, but also have extremely high requirements for advanced mathematics.

As soon as I saw this test question, even the recognized academic masters in the classroom shook their heads helplessly.
