The top class of the second middle school has always been based on the principle of teaching students according to their aptitude, and people with different specialties adopt different education methods, in order to let more students with professional specialties enter prestigious schools on top of quality education and in addition to examination-oriented education.

Therefore, in the process of selecting people, it is also a separate proposition.

Li Lechen did well in mathematics, and the comprehensive science was only 3 points short of the full score, so the focus of his test was this kind of question.

Simple, naturally there is no need, what you want is to be able to do difficult problems.

A set of test papers, jointly produced by the teachers of mathematics, physics, chemistry and biology, includes two pure mathematics questions, one pure physics question, and two science comprehensive questions.

The questions came out of the printer, A4 paper, and there were exactly four questions on one side.

"You just do these four questions. Zheng Fangxing took the question off the printer and said to Li Lechen, "It's ten o'clock now, let's do twelve." ”

"Can I submit the paper in advance?" asked Li Lechen.

“......”

Zheng Fangxing suddenly didn't react, he hadn't even read the question, so he asked if he could hand in the paper early, maybe he was too confident, right?

Or is it ......

"If you can't do it at all, I'll contact your parents, you have a problem with the mock test. Zheng Fangxing directly received a dose of preventive injection.

"No, no, no!" Li Lechen denied Sanlian, "I'll simply ask if I can hand it in early if it's done, I'll ...... My bedroom hasn't been cleaned yet!"

This reason is not a reason, after all, I was suddenly called over for the exam.

However, Zheng Fangxing still feels a bit ridiculous, generally the standard answer time for such a big question is 20 minutes to half an hour, and now the four questions are given 70 minutes, which is really below the standard answer time.

However, after nearly 30 years of teaching, it is not unseen that Xueba has never seen it, although Li Lechen, who has been teaching for two years, does not look like a genius Xueba, but it is difficult to ensure that he will improve by leaps and bounds after a summer vacation.

So Zheng Fangxing still nodded.

With this nod, Li Lechen was also happy. He was afraid that he would be bored if he had done the question early, and then he would sit here and count the cobwebs.

So according to the position pointed out by Lao Zheng, he sat down at a teacher's desk and began to do the question.

"Scratch paper is here. Zheng Fangxing pointed to the printer on the table, and there was a lot of A4 paper in the carton.

"Oh. Li Lechen replied casually.

Then, Zheng Fangxing returned to his desk and continued to work on the computer. Solving questions is a technical job, and it is also one that Zheng Fangxing needs to consume a lot of time every day.

With the intelligent assistant, Li Lechen doesn't need to go to the live broadcast for help at the moment, and the intelligent assistant is comfortable in the face of the problem in front of him.

The key is that this intelligent assistant is really automatic and user-friendly, it should be that Li Lechen doesn't understand many formulas and nouns, so he directly presents the solution steps on the virtual screen in the form of a barrage.

So, Li Lechen didn't have to understand what the topic was talking about at all, he just copied it step by step.

Within a few minutes, a copy was made.

Li Lechen subconsciously wanted to take out his mobile phone to see what time it was, and at the same time estimated how to allocate the time for his next three questions, and suddenly thought that he was taking the exam.

So he looked up and asked, "Teacher, what time is it?"

"Didn't you bring your phone?" Zheng Fangxing was immersed in the sea of questions, and he didn't even want to look at the lower right corner of the computer.

Cell phone...... Li Lechen twitched the corners of his mouth, remembering Lao Zheng's sharp-eyed appearance when he took the mathematics test the day before yesterday, and couldn't help but sigh that the treatment of Xueba in the teacher was different.

It seems that going to the top class is not only a benefit, the teacher is really kind to the top students.

Without thinking much about it, he took out his phone and looked at the time.

10:55 a.m.

In other words, Li Lechen only did the big question just now, oh no, he copied it for five minutes.

In fact, copying for five minutes is already a long time, and it belongs to the kind that is very serious about copying down. But Li Lechen knew that this time was also ridiculously short.

I don't know how to do the questions, but normally it should take three to five minutes to review the questions, three to five minutes to make a draft calculation, and another five minutes to write the answer when the calculation is smooth, so ten minutes should be the shortest.

Li Lechen secretly limited his time to 40 minutes for these four questions, so that it should be more reasonable to hand in the paper at half past eleven.

Thinking so, Li Lechen slowed down and chatted with the intelligent assistant with his mind.

"Can you tell me a little bit about what you do?"

"First of all, I have Ten Trillion Whys in my program, so I have all the knowledge in reserve. "Secondly, if I am fully automated, I can act as your bodyguard, alerting you when danger is approaching." ”

This is very good, I have felt that Wang Dazhuang tried to attack him from behind, but was startled by himself, Li Lechen felt that this smart bodyguard was indeed very reliable.

"How far can you do this?"

"To put it mildly, there's a flu wave coming at you, but not in enough concentrations to get you. The smart assistant explains.

"Really?

"Ahh

Without waiting for the intelligent assistant to affirm, a loud sneeze came from behind him.

It seems that the flu virus is real.

"This one is too small, so what if it's a bigger one?"

"A plane is flying over where you are, but it's not in danger of crashing, so I didn't alert you to safety. ”

“......”

The possibility of this kind of thing happening is indeed very small, but being able to detect it so far is beyond Li Lechen's expectations.

"Let's talk about something realistic, it's not big or small, what does it affect me?"

"It's not influential, but it's not insignificant, right now, 35 degrees behind you, outside the window, there's a guy staring at you, and from the brainwave analysis he's collected, he has a certain degree of malice towards you, but he's not ready to take action. ”

"it!"

Li Lechen was startled, subconsciously turned his head and looked out of the so-called 35-degree window behind the right.

At this moment, there was indeed a person standing outside the window, Liu Yu, who was also called over by phone to take the exam. He was careful and delicate, and he didn't rush into the office in one go. He kept a close eye on the people in the office while he was in the hallway.

The math teacher who is seriously solving the problem should be the legendary Zheng Fangxing.

The student who had just sneezed, wearing a pair of high-altitude glasses, was thin and short, and at first glance he looked like he had studied hard day and night and had a very poor physique.

There is a person who scratches his ears and cheeks and hasn't written for a long time, and I don't know how he is qualified to enter the top class preselection.

And what caught Liu Yu's attention the most was Li Lechen.

At this time, Liu Yu didn't know Li Lechen's name, but he clearly remembered his back, because this back inadvertently performed a magic trick to make the bottle disappear out of thin air just now.

Sometimes what seems like a simple trick, especially street magic, is actually very difficult.

On the contrary, some large-scale so-called very dangerous magic tricks of changing people and cutting off heads and hands are actually just good props and good cooperation of assistants.

Just like the magic trick that Liu Yu performed before to conjure an orange out of thin air and then turn it into a bottle of juice, not only do you have to make a lot of preparations before changing, but also take into account the scene during the performance, if there are too few people, it is not easy to change.

Only magicians understand magicians, so Liu Yu knows that the boy who is doing the question with his back to him is his opponent.
