Tianjing University, one of China's institutions of higher learning, is home to almost all talents.

It's Saturday, and it's supposed to be a day off, but the auditorium is empty.

Because today is Professor Zheng Xu's lecture.

Zheng Xu, a professor in the Department of Chemistry at Tianjing University, is one of the few male professors who are popular with students. Not only because the lectures he teaches are simple and easy to understand, but also because he is the dean of teaching.

Dean of Teaching, Ah, there is wood! This field must be held!

"I think everyone should know what a photochromogenic compound is, which is a compound that can reversibly undergo color change under the action of light......" Zheng Xu put his hands on the solid wood lectern, talking, his voice echoed throughout the auditorium through the sound, "Photochromic change is often associated with changes in molecular structure......

On the stage, Professor Zheng Xu spoke happily, and off the stage, a classmate lay on the table and snored gently, looking like he was sleeping soundly.

On either side of him, two classmates were lip-syncing.

"Hey! Leng Xuan, how long did this guy Awen masturbate last night? Look at him sleepy! Zhang Yang was dedicated to two things, pretending to be listening carefully to the class, while mouthing at Leng Xuan on the other side.

"How do I know?" Leng Xuan glanced at Zhang Yang and said, "We are not from the same dormitory." ”

"Do you want to wake him up? I feel like I'm going to have to sleep like this! ”

"I also have an ominous premonition, let's call him quickly."

As he spoke, the two of them were ready to wake up the sleeping Zhengxiang's classmate named Shi Wenpeng.

But their movements were still a step slower, and Zheng Xu's eyes were staring at Shi Wenpeng like an eagle.

Good boy, have the guts to dare to sleep in my class! I'm tired of living!

Zheng Xu raised his eyebrows, and after confirming Shi Wenpeng's seat, he spoke.

"Please count from the left in the ninth row, and the eleventh student will stand up and answer my question."

As soon as the professor's words fell, a layer of cold sweat broke out on Zhang Yang and Leng Xuan's heads.

"It's over, what should I do, I've been discovered!" Zhang Yang and Leng Xuan made eye contact.

"How do I know what to do!" Leng Xuan is also anxious, if you are targeted by Zheng Xu, the teaching director, I guarantee that you will not have a good life this semester!

"There is a Dao cloud, a dead Dao friend is not a dead poor Dao! Let's pretend we don't know him! ”

"Great idea!"

So, the two of them sat on their knees, looking like I didn't know the sleeping thing.

The corners of Zheng Xu's mouth twitched, you two are going to wake up the sleeping guy for me!!

"Ahem, the classmate sitting in the tenth seat, please wake up the classmates next to you." Zheng Xu said with a smile.

It's just that his smile is flamboyant, and it looks extremely infiltrating.

Zhang Yang's face turned white all of a sudden, and then he raised his hand helplessly.

Syllable!!

A crisp sound sounded......

"I'll rub, which grandson shoots me!"

Shi Wenpeng, who was attacked in his sleep, was furious, and someone woke him up as soon as he fell asleep! I really don't have any public morality! The most important thing is that this grandson killed him!

Shi Wenpeng stood up abruptly, and then ...... And then there was no then. He suddenly felt like his head was swelling, as if someone had suddenly stuffed a lot of stuff.

Zheng Xu's eyebrows raised, he dared to say dirty words in front of him! Good! Very good! If you don't clean up, I'll have your surname!

However, although he had made up his mind to clean him up, his face was still calm.

After all, I'm the dean! Be kind to your students!

"Ask this student to answer what are the two types of photochromism."

The questions are so simple that almost anyone who reads a book can answer them. But will Zheng Xu let Shi Wenpeng go so easily? The answer is no.

Zheng Xu said that a chemistry professor who does not dig holes is not a good teaching director.

"According to the color-changing mechanism, it can be divided into T type and P type......" Shi Wenpeng, who was in a mess in his mind, subconsciously answered the question.

"Yes." Zheng Xu pretended to nod, and then asked, "So what is the difference between Type T and Type P?" ”

"The difference between type P and type T is that the achromatic process is still a photochemical process, not a thermochemical process."

Zheng Xu nodded. It seems that he is not a freshman or sophomore, so the difficulty of the following questions can be increased a little more.

"So what is the influence of the conformation of macromolecules on the photochromic properties of azo copolymers?"

As soon as the question came out, Zheng Xu looked at the classmates below who had changed their faces, and felt a sense of relief in his heart.

Sample, I can't get you down!

"It is mainly reflected in the fact that the polymer containing the azo group on the side chain is particularly obvious, if the copolymer is at a high pH value, he curls into a clump, which slows down the cis-trans isomerization of the molecule, and the rate of photochromic change is slower than that of the azo model compound of the small molecule. At low pH, the straightening of macromolecules makes the transition of cis-trans isomerism easier, and the chromogenic and achromatic reaction rates are faster than those of small molecule compounds. ”

it!

Zheng Xu almost suffocated to death without taking a breath, this question may not be able to be answered even by a senior!

However, Zheng Xu said that even if you answer it, you will never be able to answer the next question! Hey, hey, hey!!

"What happens to spirolan photochromic polymers under the action of ultraviolet rays."

It's hard to say that the problem is difficult, and it's not difficult to say that it's not difficult. Because this question is so biased!!

The students looked at Shi Wenpeng with interested eyes, wanting to know if he could answer.

"! Is this a crossing? Shi Wenpeng finally sorted out the chaotic memories in his mind and came to such a conclusion.

However, this conclusion made him feel a deep stomachache. You said that you wrote it well, and you didn't do anything big to hurt the heavens and reason, why did you cross over, and you said that you wore it to another world, forget it, and threw it to the parallel world for Mao! It's not a place where heroes are useless, it's not!

Waste of resources!

You must know that a street writer is very precious!

"Classmates! Please answer the question! Zheng Xu pressed his throat, trying to make his voice sound more majestic.

Sample! I can't answer it! Let me think about how to punish you and deduct credits? It's boring, I'm tired of playing. Corporal punishment? The dean said that he was a good person and never physically punished his students.

Shi Wenpeng's thoughts were called back by Zheng Xu, but ......

"What, professor, can you explain the question again, I didn't hear it too clearly......" Shi Wenpeng said cautiously.

From the memory of the original owner of the body, Shi Wenpeng made a summary of Zheng Xu.

That is: the dean of academic affairs who does not come up with new tricks is not a good chemistry professor!

"Then I'll say it again." Although he smiled in his heart, Zheng Xu still nodded calmly and said, "What kind of changes will occur to the snail photochromic polymer under the action of ultraviolet rays." ”

"Uh...... This ......" Shi Wenpeng racked his brains to recall the memories of the original owner, but ...... Nima's profession is not right!!

This is the content of the elective course, who will study it in depth! Isn't that sick!!

Holding back, Shi Wenpeng finally held back two words......

"Guess ......"

Zheng Xu: "...... Huh"

Zhang Yang: "......"

Leng Xuan: "......"

Students: "......"

Damn, you're teasing me, right? This must be teasing me!!

Zheng Xu is messy! He said that the dean of education who does not physically punish students is not a good chemistry professor!!!!!!!!

As soon as the words came out, Shi Wenpeng regretted it! He can't wait to smack himself in the mouth! What a mouth! It's so cheap!

"What's that, professor, I'm talking about playing......" Shi Wenpeng said weakly, trying to deduct a way out of Zheng Xu's hand.

"Oh, that's just talking." Zheng Xu smiled, smiling very sunny and bright, but there were a little more wrinkles on his face, like a chrysanthemum.

"Now! Immediately! Right away!! Go out for a lap for me! Don't let me run ten laps around Beijing University, don't stop! ”

Ten laps!

"Classmates! Please answer the question! Zheng Xu pressed his throat, trying to make his voice sound more majestic.

Sample! I can't answer it! Let me think about how to punish you and deduct credits? It's boring, I'm tired of playing. Corporal punishment? The dean said that he was a good person and never physically punished his students.

Shi Wenpeng's thoughts were called back by Zheng Xu, but ......

"What, professor, can you explain the question again, I didn't hear it too clearly......" Shi Wenpeng said cautiously.

From the memory of the original owner of the body, Shi Wenpeng made a summary of Zheng Xu.

That is: the dean of academic affairs who does not come up with new tricks is not a good chemistry professor!

"Then I'll say it again." Although he smiled in his heart, Zheng Xu still nodded calmly and said, "What kind of changes will occur to the snail photochromic polymer under the action of ultraviolet rays." ”

"Uh...... This ......" Shi Wenpeng racked his brains to recall the memories of the original owner, but ...... Nima's profession is not right!!

Holding back, Shi Wenpeng finally held back two words......

"Guess ......"

Zheng Xu: "...... Huh"

Zhang Yang: "......"

Leng Xuan: "......"

Students: "......"

Damn, you're teasing me, right? This must be teasing me!!

Zheng Xu is messy! He said that the dean of education who does not physically punish students is not a good chemistry professor!!!!!!!!

Shi Wenpeng's face turned green, Nima, this is going to die! It's really going to die!

However, looking at Zheng Xu's iron-blue face, Shi Wenpeng swallowed his saliva, didn't dare to say a word, obediently walked out of the door of the auditorium, and started his own big business of running circles.

The cool wind of autumn blew the earth and blew on Shi Wenpeng's body, but this did not make him feel cool at all.

The heat generated by the strenuous exercise swirled around his body, causing him to lie on the stone table in the pavilion like a dead dog.

"It's not me talking about you, you're handsome today!" Leng Xuan sat opposite Shi Wenpeng, bared his teeth, and gave him a thumbs up.

"Get out...... Shi Wenpeng said weakly, if it weren't for the fact that his lower body was already unconscious, he would definitely kick this guy who said cool things.

Ten laps! Ten whole laps, bastard! Shi Wenpeng feels that it is a miracle that he can survive now.

"Xiao Shi, brother really envy you, really." Zhang Yang, who was sitting on Shi Wenpeng's left hand, pretended to say in a deep voice, "It's only been one class, and all the girls remember you, hey!" Ay! Ay!! ”

Three sighs in a row made Shi Wenpeng's liver hurt! Nima, this shame was thrown to the sister, I guess the whole school will know about it tomorrow......

As soon as he thought of this, Shi Wenpeng wanted to cry, what is the matter!

"By the way, let's discuss what to eat first." Leng Xuan took out his wallet from his pocket and glanced at it, "I have less than five thousand yuan left this month." ”

"Five thousand, a lot, I have more than three thousand left." At the mention of money, Zhang Yang's face became bitter.

Two days ago, I spent more than 3,000 yuan on my girlfriend's birthday, booking a table, inviting friends, buying a birthday cake, and preparing a birthday gift! More than 3,000! How many buns can you buy!

I really can't live.

"Hehe......" Shi Wenpeng rested his chin on the stone table and glanced at the two of them with disdain, "You guys are good, I have more than seven hundred and less than eight hundred yuan left." ”

"I'll go! What did you do! Spend money so fast! Leng Xuan and Zhang Yang said they didn't understand, because according to the usual point of view, among the three people, this product is the most money-saving! The two of them were relieved by Shi Wenpeng.

"I bought a notebook yesterday and spent more than 8,000 yuan." Shi Wenpeng smiled and said.

"I'm dizzy!"

"Kneel!"

The two of them are completely convinced.,This product obviously already has a notebook.,Still buying? It's really a lot of money, and my back hurts!

"What's that, you two send me back to the dormitory first, it's a bit cold......"

I sweated, and then I was blown by the cold wind, it's no wonder it's not cold!

Leng Xuan and Zhang Yang were helpless, so they had to take him back to the dormitory with one arm alone.

Back in the dormitory, Shi Wenpeng lay on the soft big bed and screamed comfortably!

All the tiredness in his body seemed to disappear the moment he collapsed on the bed.

"What do you eat? We'll bring you back a little later. Leng Xuan asked after closing the wide open window.

"Whatever, I'll eat whatever you buy." Shi Wenpeng squinted his eyes and said.

"Okay."

"By the way, don't buy seafood, I don't touch that." When it was over, Shi Wenpeng shouted at the backs of the two people.

"Got it, you can rest."

After saying that, the door of the dormitory was closed by two people.

After lying on the bed for a while, Shi Wenpeng felt a little bored, reached out from the table and picked up the new notebook he had just bought, put it on his lap, leaned on the edge of the bed and started surfing the Internet.

Although the notebook is newly bought, it has all kinds of good software, such as chat tools, music software, and almost everything that should be available in addition to games.

Habitually opened the penguin and entered the account number and password. However, when logging in, a prompt pops up.

"The account you are logged in to is not registered or the password has been entered incorrectly."
