Reborn as an oil tycoon

Chapter 38 Questions
There is no doubt that this night was extremely difficult for Liu Shang.

The inside of the stomach was turbulent, burning and uncomfortable, and almost vomited all night.

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

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

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

When he woke up the next day, everything else in the dormitory had been washed and he was ready to go out.

In Liu Shang's state at this time, it was naturally impossible to go to work, so after getting up and changing his clothes, he went directly to class with him.

Since he was still retching in the morning, he only drank some water and didn't dare to eat.

After learning that Liu Shang was going to class through a text message, 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.

On the way, I also happened to meet Zheng Jiao.

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

Early the next morning, she withdrew [-] 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 with her own hands.

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

When the two of them came outside the classroom, the atmosphere in Liu Shang's classroom was extremely oppressive.

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

Today, I happened to bump into Li Wenzhong, the teacher who was the most dissatisfied with him, who taught surfactant chemistry.

After attending this class for a period of time, Li Wenzhong finally couldn't bear it anymore and waited for the questioning session.

"Let's start asking, what is surfactant micellization?"

"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 nodded.

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

"I think you may have a big opinion on me, which is why you never come to my class."

"Or does it mean that you know all the content I taught, and you don't think it's difficult?"

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

After Li Wenzhong finished speaking, everyone in the classroom couldn't stop laughing, and everyone who had a good relationship with Liu Shang also slapped their foreheads, waiting to see Liu Shang make a fool of himself.

In fact, their laughter was not malicious, presumably any student who was absent from class every day would feel like this when asked by such a teacher by name, and felt happy.

Seeing this scene in the classroom and Li Wenzhong's loud and angry voice under obvious self-control, Jiang Ruolin outside the classroom door frowned, her eyes were full of worry.

Seeing her like this, Zheng Jiao at the side also sighed softly.

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

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

"If you have the opportunity, you should persuade him. He may be excellent in ability, conversation, and other aspects."

"However, if you often fail courses, fail to graduate normally, or even suspend school, the two of you will never talk about any future."

"Actually speaking from the bottom of my heart, before yesterday, like everyone else, I thought the two of you were very inappropriate, and he was absolutely not worthy of you."

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

"I'm also very curious about how the two of you will become when the university is about to end a few years later? Will you really go to the end?"

"So, if you have a chance, you should advise him not to put the cart before the horse, stop aiming too high, and play with things."

In fact, Zhou Liang, Tan Feng and others have long known about Liu Shang's frequent absenteeism and the fact that many teachers have turned on red lights.

They were just waiting, until the thunder was getting bigger and bigger, and was about to explode, before going to Jiang Ruolin's side to deal a fatal blow to Liu Shang.

Because of the changed impression of Liu Shang in his heart, as well as his aversion to Zhou Liang and others' despicable behavior, Zheng Jiao kindly burst the bubble ahead of time.

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

Seeing her firm opinion of Liu Shang, Zheng Jiao shook his head unreasonably.

"Ruolin, none of us are ostriches who can bury their heads in the sand."

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

When the two of them were talking, Liu Shang in the classroom showed a wry smile, and unexpectedly, he actually answered Li Wenzhong's question.

Perhaps because of the surprise and abruptness at this moment, the classroom became more and more quiet, and Li Wenzhong on the podium could not help but frown, and directly asked the second difficult question:

"Liu Shang, please answer again, what are the surface-active hydrophobic groups in the market?"

Without the slightest hesitation, Liu Shang blurted out, "Is it a hydrophobic group?"

"Natural fatty acids, petroleum paraffins, alkylbenzenes, alkylaromatics, alkylphenols, polyoxypropylenes, silicone resins."

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

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

However, the top students 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 widely used in a few years or more than ten years.

It is very effective in reducing surface tension, but slightly less effective in changing the interfacial tension of oil and water.

Even the lecturer Li Wenzhong was not very familiar with this cutting-edge technology, so when Liu Shang mentioned this, even he was taken aback for a moment.

"Oh, I have to say, your answer this time is very good, maybe you also read the book in advance before coming to class today."

"Next, I'm going to ask you a calculation question, using the Debye-Huckel formula to calculate the activity coefficient of a surfactant solution."

Afterwards, with a swipe of his pen, Li Wenzhong wrote down a series of extremely difficult questions on the blackboard.

Don't talk about doing it, even looking at it will make people feel headache and dizzy.

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

Seeing this test question, even the recognized masters in the classroom shook their heads helplessly.
