After class, many people hurriedly made small movements, and as the class bell rang, Teacher Liao walked in triumphantly with the test papers.

"It's good, I can see that everyone is taking this exam very seriously, so I won't waste any time. The students sitting in the first row keep a copy for themselves and pass the exam paper to the students in the back. ”

The students were not in a hurry, but pretended to browse the exam questions and thought hard. As soon as Ye Yuhu and Lao Liao turned around, he quickly took out a blank piece of paper from under the drawer, his movements were secretive, and his voice was subtle, even the national spies did not do as well as him.

He was already the focus of attention, and the reflection in Lao Liao's glasses swept to Ye Yuhu, and immediately rushed up with an arrow and grabbed his hand: "Hehe, the cheater has zero points, let me see what kind of broken answer is pressed on your paper." ”

Ye Yuhu innocently spread his hands helplessly: "Teacher, this is my scratch paper." ”

Lao Liao's eyes widened, the blank piece of paper was empty, and there was not a word: Could it be that I was too careful? coughed and said: "It's good if you don't cheat, you have to get good results in the test based on your true level." ”

When Lao Liao transferred to another group of patrols, Ye Yuhu quietly took out a mineral water bottle and dropped a few drops of transparent liquid on the white paper, showing a row of dense purple-red small characters, which was the answer.

Liao Xuebing immediately turned around sharply, pointed at Ye Yuhu and said, "Hehe, I finally caught you, and you dare to play yin with me." Stop immediately or you will be disqualified. ”

Ye Yuhu shook the piece of paper and said with a smile: "Teacher, it's not illegal to use scratch paper in the exam, right?"

Lao Liao walked over, took the draft paper, there was nothing on it, he pushed the black-rimmed glasses hard, and said in his heart: "Am I really dazzled?"

It turned out that the paper was filled with a colorless phenolphthalein dilution, which was invisible to the naked eye, and then dropped into a dilute NaOH solution, a chemical reaction would occur, changing into a purple-red, and as long as it was slightly shaken, the purple-red color would disappear. Ye Yuhu played him twice in a row, and he was extremely proud.

"Mengjun, what are you looking at?" shouted Lao Liao.

Meng Jun rolled up his sleeves and shook them twice in the air, "Teacher, I can't even look at my watch?"

Liao Xuebing took off his watch and examined it carefully, except that the body was a little big, no matter how you looked at it, it was just an ordinary electronic watch, and the button on the side of the dial was pressed several times but there was no response, he grunted and returned the watch to Meng Jun.

Meng Jun smiled sinisterly, continued to fiddle with the watch, pressed the button a few times, the dial popped open, and it turned out that there was a delicate mobile phone in the middle, and the screen was full of answers.

"Murong Lanluo, you don't sit down, what are you doing crooked to the side?" Lao Liao shouted again.

"Idiot. Murong Lanluo said in a low voice, lightly touching the ear stud set in the earlobe, which was a small tape recorder headphone, and the answer to each question would be transmitted from the earphone into the ear.

Liao Xuebing inspected for twenty minutes, nervous, cautious, and his eyes were like torches, but he found nothing, so he had to walk back to the podium and sit on a chair.

Liao Xuebing took off his glasses, wiped them again and again, put them back on, and saw more clearly. Good...... I'm really right as a teacher, it doesn't matter if I explode cigarettes, it doesn't matter if I get a turtle portrait, it doesn't matter if I lose 4,500 yuan in betting, as long as I can get close to these innocent female students, I don't care about anything.

The bell rang after class, and he slowly collected the test papers, only hating why time passed so quickly, if there was one more hour, no, two hours, how nice it would be!

At noon, he did not go back to the dormitory for lunch break, and continued to stay in the office to correct the exam papers. Every time he changed a paper, he was surprised, it was so awesome, how could he do so well in the exam, the file left by the previous head teacher is still there, and the record on it says that only half of the people passed the Chinese class exam, which is too weird. Could it be that my old Liao's character couldn't be better, they have been studying hard this week, and their grades have improved by leaps and bounds?

Looking at it further, the answers to each exam paper were similar, and there was a typo in one place that was so obvious that it couldn't be more obvious, and almost half of the people wrote it like this, so it was clear that someone had cheated. In the theoretical question: "Please explain the relationship between Zhu Bajie and Tang Seng." Everyone has the same answer: in fact, Tang Seng is equivalent to the leader of a team, and Zhu Bajie is his male secretary, both of them have the same characteristics, they are diligent in thinking, lazy to do things, and more or less have a woman's relationship, which may explain why they smell the same, so that Sun Wukong is excluded, maybe, Tang Seng has a subtle feeling similar to Zhu Bajie similar to Brokeback Mountain, because Zhu Bajie always pleases Tang Seng, often talks sweetly, and Tang Seng likes to protect Zhu Bajie's short ...... What a mess.

That Ding Liujing is usually very quiet and very ladylike, every time she gives a lecture, she sits upright with her legs together, why is it this time......

Liao Xuebing threw the pen on the table and thought angrily: "I've been tricked again!"

It is unforgivable that Lao Tzu made such a low-level mistake in vain. Forget it, let them pass the test for the time being, and I will talk to Ding Liujing alone in the future......
