"Looks like this isn't the first time someone has thrown you a note, right?" Guo Xiang asked.

"Well, it's not!" Gu Zhennan nodded.

"Huh?" Guo Xiang's eyes widened.

"But I've never seen it." Gu Zhennan replied, "I don't have that much to work on. ”

Guo Xiang sneered, count yourself conscious.

stayed in the library for one class, and there was a class in the next class, Gu Zhennan took Guo Xiang to class, and the two sat together.

Zhou Qing was very surprised to see Guo Xiang, just now in the library, he thought that she was only sitting with Gu Zhennan occasionally, why did she come with her now, could it be that they were together?

What class is she in? How come I've never seen one?

At this time, the teacher began to roll call, Guo Xiang took a look, isn't this Teacher Zhu? In his previous life, he lived next door to his house, and when he was a child, he used to visit his house.

But at that time, my father was a teacher of the oil family, and in this life I changed to my mother, I don't know if he is still a neighbor, but anyway, my mother is a teacher at the University of Petroleum, so he should know him, right?

Zhou Qing kept an eye on Guo Xiang when Teacher Zhu called her name, and found that she didn't respond, isn't she a student at school?

Mr. Zhu started the class, and this class was "Petrochemistry".

When it comes to some low-grade oil wells, the production is not much after one production, and secondary and tertiary production can be carried out.

There is not only oil in the oil well, but also water and gas, and gas is natural gas, and if there is enough natural gas, it will be spewed out and become a self-blowing well.

This is the first oil recovery, and after the injection is over, the reservoir enters the secondary oil recovery stage. Because the oil, water and gas in it are insufficient, the oil is very thick and cannot be pumped, so it is necessary to inject water and gas to pump it out.

The remaining water injection and gas replenishment are useless, the oil has been concentrated like asphalt, and it is about to reach a solidified state, at this time, it is necessary to add chemical reagents, carry out polymer flooding, and use chemical polymers to soften the heavy oil before it can be extracted.

Guo Xiang felt quite interesting when he heard this, he seemed to have heard his father say it in his previous life.

Zhou Qing kept staring at Guo Xiang, and when he saw her and Gu Zhennan whispering a word from time to time, Gu Zhennan also smiled and nodded, and couldn't help but be jealous in his heart.

Usually he is such a cold person, she still thinks that he is the same as everyone else, why is he so special to this girl?

And what he said just now was so hurtful, he had been in the same class with him for so long, and he didn't know himself? Is it okay to be praised as the class flower by your classmates?

Isn't that woman dressed in a foreign way? What's the big deal?

The more Zhou Qing thought about it, the more angry he became, and suddenly stood up.

"Do you have any questions, classmate?" Teacher Zhu looked at Zhou Qing.

"I ......" Zhou Qing was a little flustered, and suddenly pointed to Guo Xiang, "Teacher Zhu, she is not from our class, no, she is not even a student of our school, I don't know how to get in." ”

Everyone looked at Guo Xiang curiously, what's going on?

Guo Xiang rolled his eyes, what do I have to do with you when I come in?

"Teacher Zhu......" Gu Zhennan just wanted to stand up and explain, Guo Xiang pulled him, smiled and said, "Why, students who are not Teacher Zhu can't come to the class?" I think Mr. Zhu's class is very interesting, I have admired it for a long time, can't I come to audit? ”

"You are talking nonsense, you are not a student of our school at all, how can you come to audit? You're coming, you're coming......" Zhou Qing couldn't say it, saying that she was here to talk to Gu Zhennan? Then everyone doesn't know that he has a partner?

"Teacher Zhu, may I ask, can't you come to your class if you are not your students?" Guo Xiang looked at Teacher Zhu.

"Absolutely." Teacher Zhu nodded, he was naturally very happy to have students choose his class.

However, it seems that he has not seen this student before.

"You said you came to listen to my class? Then let me test you, what chemical reagents are used for polymer flooding? Teacher Zhu looked at Guo Xiang.

Gu Zhennan's heart suddenly lifted, his daughter-in-law doesn't understand this, right?

Zhou Qing also smiled proudly, see how long can you pretend? You're going to show your stuffing, right?

Guo Xiang smiled faintly, "It's polyacrylamide, Mr. Zhu, am I right?" ”

Teacher Zhu nodded with satisfaction, "That's a good answer!" ”

No way! Zhou Qing was shocked, he didn't even know.

Gu Zhennan was also surprised, but thinking that her daughter-in-law said that she never forgot it, she must have read the book, right?

"But, but she's not ...... at all," Zhou Qing was anxious.

"Teacher Zhu, in fact, I am really not a student at school." Guo Xiang smiled: "You don't remember me? I'm Guo Yaqin's daughter......"

"Are you...... Xiangxiang? Teacher Zhu pushed his reading glasses and looked at Guo Xiang carefully, "No wonder you understand this, it's not strange that it's Teacher Guo's daughter." ”

Teacher Zhu smiled, "Didn't I hear that you are studying in a medical university?" Why did you come to my class? ”

"I just came to the school to have a look, and I happened to come across your class, so I came to listen, your lecture is still so good, I was fascinated by it." Guo Xiang took the opportunity to pat himself on the back.

Teacher Zhu laughed, "It's good that they're all like what you said." ”

The students looked at the two of them dumbfounded, hey, the teacher is in class, why are you still talking?

"Just right, take advantage of today's opportunity, Mr. Zhu, let me introduce you, this is my lover." Guo Xiang pulled Gu Zhennan up, "Please take care of Mr. Zhu in the future!" ”

"Huh? Are Gu classmates married? ”

"Is this his daughter-in-law?"

"No wonder he is so cold, I originally thought he was unkind, it turned out that he had a daughter-in-law."

"That's right, it's so beautiful, I don't care about others......"

"They are still top students in medical universities......

"Classmate Gu is deeply hidden......"

Zhou Qing's face turned white, how could this be? We're only sophomores, how could he get married?

Teacher Zhu looked at Gu Zhennan and had a little impression of him, he was newly transferred, but he worked very hard.

He nodded, "That's good." ”

"Sit down, now go back to class!" Teacher Zhu said.

Guo Xiang and Gu Zhennan glanced at each other, and the two sat down together, Gu Zhennan was not embarrassed because Guo Xiang said that he was her lover, but took it for granted, originally he wanted to let everyone know that he had a daughter-in-law, but now it is easier.

Gu Zhennan reached under the table and held Guo Xiang's hand, she glared at her and pursed her lips and smiled.

Zhou Qing watched the interaction between the two from the side, and his teeth were about to be crushed.

After class, the two went to the cafeteria to eat together.

The handsome man and the beautiful woman caused another wave of onlookers.

Both of them are calm emperors, and they are not affected in the slightest.

"Today's mission is complete." Guo Xiang looked around and clearly told others that Gu Zhennan was a master of the grass, so don't beat his idea.

"Now you can rest assured?" Gu Zhennan smiled, why is the little daughter-in-law so cute?

"If there's still that shameless entanglement, you're welcome." Guo Xiang said.

"Okay, I'll listen to you." The corners of Gu Zhennan's mouth hooked.
