Chapter 448 (1/2)

When the bell rang, an old white haired professor with thick glasses came in.

The old professor put down his book and said, ”today is the first day. I won't call the roll. I'll inform the students who haven't arrived. If you're caught skipping classes three times this semester, you'll lose the course. ”

”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, ”Liu Qingyi brought a boy over. This is a classroom. Should we let the extra people leave?”

”Oh?” The old professor took a look at the waves.

Liu Qingyi got up and said, ”teacher, he's my friend. He's here to listen in. The school doesn't forbid outsiders to listen, should it be allowed? ”

”Teacher, it's too unruly.” Zhou Guangwen frowned.

The old professor said in a deep voice: ”it's unnecessary to care about this kind of rule. Of course you can listen in. There is no end to learning. This attitude of being willing to learn is very good. Well, don't waste time on this. Please take out your textbooks. Today we are going to talk about a more difficult formula. ”

The old professor began to give lectures. Zhou Guangwen was in a bad mood.

Shen Lang was idle and bored, and he also heard it.

It was Liu Qingyi who was impatient after listening for a while. He covered his face with his textbook and talked to Shen Lang in a low voice. His playful appearance seemed a little cute.

After contacting Liu Qingyi for a period of time, Shen Lang also found that she was cold outside and hot inside.

”That's the formula. Do you understand it? OK, let's do a problem to consolidate it The old professor took the book and wrote down two questions on the blackboard. He said to the students, ”these two questions are a little difficult. It's nothing if you can't solve them. After all, the formula is too complex. 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 and showed confused expressions.

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

Only a few Zhou Guangwen level figures racked their brains to be the first to solve this problem.

For some Xueba, this is equivalent to a competition.

Shen Lang took a look at the topic with great interest and kept it in mind.

After ten minutes, Zhou Guangwen was the first to stand up and say, ”teacher, I've worked it out. Is the answer to the first question 1?”

”Oh, you worked out one!” The old professor laughed and praised: ”you are right. The answer to the first question is really equal to 1. It seems that you should have made this formula clear. If you take the postgraduate entrance examination in the future, this formula should not defeat you. ”

Many students have cast an amazing look at Zhou Guangwen, who can solve this problem, is worthy of learning hegemony.

”In fact, this topic is not difficult, just need to calculate it carefully.” Zhou Guangwen said with a face.

After that, he glanced back at Shen Lang and said, ”I think all the students who have just listened carefully can work out this problem, and so can the student who has been listening in.”

All the students looked at Shen Lang, and the old professor also looked at him, but the old professor didn't have much hope for Shen Lang. This kind of problem is very difficult, you expect a person who comes to the audience on the first day to solve this kind of problem, that is just like a fool's dream.

Zhou Guangwen wanted to find Shen Lang's trouble on purpose. He said directly, ”what do you think of this problem, this fellow listener?”
