Godly Dragon Guard

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

The old professor put down the book and said: “Today is the first day, I will not call the names, but will inform the students who have not arrived. If this semester is caught and missed three times, then the homework will be suspended.”

“Teacher, no one in our class is absent today. And there are more people!” 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 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 listen. The school does not prohibit outsiders to listen. It should be allowed?”

“Teacher, this is too unruly.” Zhou Guangwen frowned.

The old professor said in a deep voice: “This kind of rules don’t need to be concerned, of course you can watch. There is no end to learning. This kind of willingness to learn is a good attitude. Well, don’t waste time on this matter. Please take it Textbook, today we are going to talk about a more difficult formula.”

The old professor started to lecture, and Zhou Guangwen was in a bad mood.

Shen Lang was bored idle, and also heard it.

But Liu Qingyi became impatient after listening to it for a while, covering his face with the textbook, and talking to Shen Lang quietly, her playful appearance looked a little cute.

After being in contact with Liu Qingyi for a period of time, Shen Lang also discovered that she was cold outside and hot inside.

“This formula is like this. Everyone should understand it? Okay, let’s do a problem to consolidate it.” The old professor took the book and wrote two problems on the blackboard, and said to the students: “This The two questions are a bit difficult, and it’s okay if you can’t solve them. After all, the formula is too complicated. However, students who want to take the postgraduate entrance examination should pay attention to it.”

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

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

There are only a few people at Zhou Guangwen level, racking their brains to be the first to solve this problem.

For some schoolmasters, this is equivalent to a competition.

Shen Lang glanced at the title with interest and remembered it in his heart.

After a full ten minutes, Zhou Guangwen stood up and said, “Teacher, I have calculated it. Is the answer to the first question 1?”

“Oh, you have 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 this formula. For postgraduate entrance examinations, this formula should not trouble you.”

Many students gave Zhou Guangwen awe-inspiring glances. It is worthy of being a scholar who can solve this problem.

“Actually, this topic is not difficult. It just needs to be calculated carefully.” Zhou Guangwen said with a grimace.

After finishing speaking, he glanced back at Shen Lang and said, “I think the students who have just listened to the lecture carefully can calculate this question, and the student who was listening can also calculate it.”

All the students looked at Shen Lang together, 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 someone who will come to the audience on the first day to answer this kind of question, it would be idiotic.

Zhou Guangwen wanted to deliberately trouble Shen Lang. He said directly: “This classmate who is listening, what do you think of this question?”

There was a burst of laughter from the whole class.

Shen Lang didn’t speak, Liu Qingyi frowned, stood up and said, “Zhou Guangwen, what do you mean?”

Zhou Guangwen saw Liu Qingyi staring at him coldly, and his mood suddenly became terrible. Anyway, he felt that there was no possibility for him and Liu Qingyi, and he simply broke the jar.

“It’s not interesting, I just want to see if your friend is in the audience to see the effect.” Zhou Guangwen said with a bitter expression on his face.

The old professor waved his hand and said, “Okay, well, don’t discuss this matter anymore. Let’s take a look at the second question, the second question. Has anyone figured out the answer?”

Shen Lang said coldly: “The answer to this question is 2.13.”

As soon as this was said, the class was quiet for a while, and then a group of students laughed.

“I said this classmate, how did you calculate such a precise number?”

“That is, everyone who has been to college should know the law of high numbers? The answers to generally difficult questions are very simple. How can they be so complicated.”

“Yeah, with a decimal point. You are too good at this.”

Everyone laughed again and again, but no one noticed, the old professor’s face on the podium suddenly solidified.

Liu Qingyi didn’t know why Shen Lang spoke suddenly, but she vaguely felt that Shen Lang should not be 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 2.” Zhou Guangwen said. He had been immersing himself in this question just now, and he already had a rough result in his mind.

The old professor then recovered, scratching his head and said: “If the answer is 2, this question can get half the score.”

Zhou Guangwen’s face was full of triumph. This kind of problem would be difficult to solve in less than ten minutes. He can get half the score in only about five minutes, and he feels pretty good.

Zhou Guangwen feels that in terms of knowledge, he is already very NB. If others don’t know that he is so good, this is a very painful thing!

So he likes to express himself.

“Huh, it’s just half the score.” Guan Jing hummed, she couldn’t understand Zhou Guangwen’s face.

The old professor took a deep look at Shen Lang and said: “In fact, the real answer to this question should be 2.2. In the postgraduate entrance examination, this kind of question is generally used as a bonus item. The result of the solution is 2. , You can get half the score. If the answer is 2.2, you can get a full score.”

Having said this, the old professor paused and continued: “However, the perfect answer is 2.13. If you can get 2.23, you can get a full bonus point, usually 15 points.”

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

It was really 2.23, exactly the same as Shen Lang’s answer.

All the students looked at Shen Lang again, the previous ridicule and ridicule disappeared, replaced by surprise and shock. Liu Qingyi’s boyfriend is too powerful, and he can actually calculate the result so accurately!
