Godly Dragon Guard

The class bell rang, and a white-haired old professor wearing thick glasses walked in.

The old professor put down the book and said: "Today is the first day, so I won't call the students by name. I will inform the students who are not here. If you are caught skipping classes three times this semester, you will fail the course."

"Teacher, no one in our class is absent today. And there is an extra person!" In order to vent his dissatisfaction, Zhou Guangwen stood up again, glanced at Shen Lang, and said, "Classmate Liu Qingyi brought a boy here. It’s a classroom, shouldn’t the extra people be allowed to leave?”

"Oh?" The old professor glanced at Shen Lang.

Liu Qingyi stood up and said: "Teacher, he is my friend and he is here to observe. The school does not prohibit outsiders from observing, so it should be allowed, right?"

"Teacher, this is too unruly." Zhou Guangwen frowned.

The old professor said solemnly: "There is no need to care about this kind of rules. Of course you can listen if you want. There is no end to learning, and this attitude of being willing to learn is very good. Okay, don't waste time on this matter. Please take it Out of the textbook, today we are going to talk about a more difficult formula."

The old professor started giving lectures, and Zhou Guangwen was in a very bad mood.

Shen Lang was bored and listened.

Liu Qingyi, on the other hand, became impatient after listening for a while. She covered her face with the textbook and talked to Shen Lang in a low voice. Her playful appearance looked a bit cute.

After being in contact with Liu Qingyi for a while, Shen Lang also discovered that she was cold on the outside and hot on the inside.

"This is the formula. Everyone should understand it, right? Okay, let's do a question now to consolidate it." The old professor took the book and scribbled down two questions on the blackboard, and said to the students: "This The two questions are a bit difficult, and it doesn’t matter if you can’t solve them. After all, the formulas are too complicated. However, students who want to take the postgraduate entrance examination should still take a closer look.”

The students in the class looked at the questions on the blackboard with confused expressions.

These two questions are too difficult, and few people in the class can solve them.

There were only a few Zhou Guangwen-level figures, racking their brains to be the first to solve this problem.

For some academic masters, this is equivalent to a competition.

Shen Lang glanced at the title with interest and kept it in mind.

After ten minutes, Zhou Guangwen was the first to stand up and said, "Teacher, I figured it out. Is the answer to the first question 1?"

"Oh, you calculated 1!" The old professor smiled and praised: "You are right. The answer to the first question is indeed equal to 1. It seems that you should have figured out the formula. If you’re taking the postgraduate entrance examination, this formula shouldn’t be a problem for you.”

Many classmates looked at Zhou Guangwen in amazement. He was worthy of being a top student if he could solve such a difficult problem.

"Actually, this question is not difficult. You just need to calculate carefully." Zhou Guangwen said with a stern look on his face.

After speaking, he glanced back at Shen Lang and said, "I think the students who just listened carefully to the lecture should be able to calculate this question, and this student who was listening can also calculate it."

All the students looked at Shen Lang, and the old professor also glanced at him, but the old professor didn't have much hope for Shen Lang. This kind of question is inherently difficult. If you expect that a person who comes to audit on the first day can answer this kind of question, it is nothing more than wishful thinking.

Zhou Guangwen wanted to deliberately cause trouble for Shen Lang. He said directly: "This student who is observing, what do you think of this question?"

There was a burst of laughter from the whole class.

Shen Lang said nothing, Liu Qingyi frowned, stood up and said, "Zhou Guangwen, what do you mean?"

When Zhou Guangwen saw Liu Qingyi staring at him with cold eyes, he suddenly felt terrible. Anyway, he felt that there was no possibility between him and Liu Qingyi, so he simply gave up.

"It's not interesting, I just want to see if your friend's listening has any effect." Zhou Guangwen said with a face filled with resentment.

The old professor waved his hand and said: "Okay, okay, let's not discuss this matter. Let's take a look at the second question. Has anyone figured out the answer to the second question?"

Shen Lang said coldly: "The answer to this question is .1."

As soon as these words came out, the class was quiet for a while, and then a group of students burst into laughter.

"Let me ask this classmate, how did you calculate such an accurate number?"

"That is, everyone who has gone to college should know the rules of advanced mathematics, right? Generally, the answers to difficult questions are very simple, how can it be so complicated."

"Yes, it still has a decimal point. You must be too capable."

Everyone burst into laughter, but no one noticed that the expression on the old professor's face suddenly froze.

Liu Qingyi didn't know why Shen Lang suddenly spoke, but she vaguely felt that Shen Lang was not talking nonsense.

But for such a difficult question, Shen Lang didn't even calculate it, and it was impossible to get a true answer.

"Teacher, I think the answer to this question should be." Zhou Guangwen said. He had been immersed in calculating this question just now and already had a rough result in his mind.

The old professor came back to his senses, scratched his head and said, "If the answer is yes, you can get half the marks for this question."

Zhou Guangwen's face was full of pride. This kind of problem was difficult to solve in less than ten minutes. It only took him about five minutes to get half of the points, and he felt very good about himself.

Zhou Guangwen feels that in terms of knowledge, he is already very good. It would be very painful for others not to know that he is so awesome!

So he likes to express himself.

"Humph, it's just half the score." Guan Jing snorted. She couldn't stand Zhou Guangwen's arrogant expression.

The old professor gave Shen Lang a meaningful look and said: "Actually, the real answer to this question should be... In postgraduate entrance exams, this kind of question is usually used as a bonus point. The result is, You can get half points. If the answer is ., you can get full points."

At this point, the old professor paused and continued: "However, the perfect answer is .1. If you can get ., you can get full bonus points, usually fifteen points."

Except for Qiao Xing, who was sleeping on the table, all the students in the class showed shocked expressions.

Really..., the answer is exactly the same as Shen Lang said.

The students looked at Shen Lang again, and the previous sarcasm and ridicule disappeared, replaced by surprise and shock. Liu Qingyi's boyfriend is so amazing, he can actually calculate the results so accurately! (To be continued)
