It was almost midnight, and Lin Ping was still writing hard.

"Xiaolin, aren't you sleeping yet?" Ma Zhongguo came to Lin Ping's room with his clothes on, "You didn't have dinner and hurriedly came to write, and now it's so late that you are still writing?"

"Yes. Lin Ping said without raising his head.

Ma Zhongguo picked up a book of teaching materials on Lin Ping's desk, these teaching materials were all newly changed by Lin Ping from the points store tonight, in addition to the self-mentioned "Five-year High School Entrance Examination Three-year Simulation", Lin Ping also spent points to exchange for several teaching materials about the Olympiad.

Lin Ping decided, he can't waste Wang Yige's mathematical talent, he wants to guide Wang Yige to develop in Olympiad mathematics, since Wang Yige likes mathematics so much, why not be an adult?

"Hey, Mr. Lin, where did you get these books?" asked Ma Zhongguo, flipping through the brand-new teaching materials.

Lin Ping was stunned by Ma Zhongguo's question, and then the system warning sounded.

[Warning: Your abnormal behavior has aroused the suspicion of others, and you must maintain your identity as a normal person in front of everyone to avoid arousing the suspicion of others.] When your abnormal value reaches the danger value, you will be in danger of being removed from this world!]

Lin Ping raised his head and smiled wryly: "The one in my backpack, I bought it when I came to teach, I haven't used it before, so I put it at the bottom of the bag, it is useful today, so I took it out." ”

"Oooh. Ma Zhongguo seemed to trust Lin Ping's words very much, and didn't ask too much, casually flipped the book twice and put it back on the table.

"Teacher Ma!"

Ma Zhongguo turned around and was about to walk back to the room, when Lin Ping called out to him.

"What's wrong?" asked Ma Zhongguo.

"Do me a favor. Lin Ping said with a smile, and then handed a handwritten math test paper to Mr. Ma, "This is my math test paper tonight, I have already copied one, but I still have to copy four copies, can you help me copy two copies." ”

Lin Ping, who originally only planned to take the test for Wang Yige, suddenly realized after finishing the test paper why not just let the other five people participate in it, anyway, the knowledge in the first semester of junior high school is almost finished, so it will be regarded as a preliminary exam, so he originally planned to produce only one test paper, and now he plans to copy five more copies.

"Yes, of course. ”

It seems that it is a very happy thing to be able to help Lin Ping, Ma Zhongguo put on reading glasses without saying a word, and then came to Lin Ping with a pen and paper and a stool.

Lin Ping hurriedly cleaned up a piece of space for Ma Zhongguo, so the two teachers, an old man and a young man, fought at night and used hand-copying to give the students the test papers.

Lin Ping looked at Ma Zhongguo, who was copying carefully with his head down, there was nothing abnormal, he sweated in his heart, and he suddenly had a feeling - he was like a spy who entered this world, but what he came here to do was not a bad thing, but to secretly contribute to the cause of socialist education in this world without revealing his identity.

In this way, Lin Ping's plan to help each of the five junior high school students change a set of "Five-Year High School Entrance Examination Three-year Simulation" cannot be implemented, otherwise so many books will suddenly pop up, even a fool will think that Lin Ping has a problem and is not normal.

Lin Ping can't explain to others that he is actually Doraemon Tinker Bell, and then he has a four-dimensional pocket that can do whatever he wants.

However, this strengthened Lin Ping's previous idea: that is, to take advantage of the National Day to go to the city to buy some things, and also bring the children with them, so that they can also go to the city to open their eyes.

The most important thing is to go to the city to see if you can help Liu Dazhu find a better place where he can give full play to his talents.

"College students are college students," Ma Zhongguo sighed while helping Lin Ping copy the test papers, "The level is high, not only can't I write these questions, but I can't do them." ”

Hearing Ma Zhongguo's praise, Lin Ping smiled embarrassedly and said: "Where is it, where is it, I also read the teaching and auxiliary materials, and I am now learning and selling." ”

Ma Zhongguo is not only copying the test paper, but also thinking about the questions on the exam paper, which can also be said to be doing this test paper, and when he encounters a problem that he doesn't understand, he will stop writing and ask Lin Ping. And Lin Ping also took the trouble to help Ma Zhongguo answer questions.

One is copying and learning, the other is copying and teaching, and by the time the two of them finish copying, it has already come to one o'clock in the morning.

The two raised their heads at the same time and smiled at each other, Lin Ping took the test paper copied by Teacher Ma and said thankfully: "Thank you, Teacher Ma!"

"Hey," Teacher Ma shook his head, "I thank you so much, you are not only the children's teacher, you are also my Ma Zhongguo's teacher!"

"Teacher Ma, don't say that, you can't afford it, you can't afford it!" Lin Ping said flatteredly.

"Teacher Lin, being too modest is pride!"

After Ma Zhongguo said this, the two laughed tacitly, and they were already a pair of old friends.

Ma Zhongguo has always been a studious person, although he is old, his heart is not old, but he has not had enough learning conditions before. After Lin Ping came, he was not only the children's teacher, but also became half of Ma Zhongguo's teacher, constantly helping Ma Zhongguo improve his teaching and knowledge level.

The next day, after the Chinese class, Lin Ping said mysteriously: "We won't have a math class in the next class!"

"Huh, no class?" Liu Xiangqian looked at Lin Ping with a surprised expression, "What are you doing if you don't go to class?"

"That's it, what are we doing when we don't have class?" Feng Xiao asked puzzled.

"If we don't have class, then let's play games together, play eagles and catch chickens!" Li Shulin excitedly proposed.

"Of course not," Lin Ping said with a smile, "We'll take the exam next class!"

"Exams, good exams!"

Liu Xiangqian said happily, and the other children did not show disgust on their faces.

Children in the mountains rarely take exams, so exams have become a very unusual thing.

When it came to math class, Lin Ping asked everyone to sit separately, and then took out the test paper that he copied with Teacher Ma overnight last night and distributed it.

"Teacher!" Liu raised his hand forward.

"What's wrong?"

"Wang Yige is not from our junior high school class, does he also have to take the exam?" Liu Xiangqian seemed a little unhappy, perhaps Wang Yige's existence challenged the self-esteem of these people as junior high school students.

"Yes, Wang Yige is very good at mathematics, so he also came to take the exam, you have to do this test paper well! Lin Ping said to Liu Xiangqian with a smile.

"Impossible!" Liu Xiangqian slapped his hand on the table, "I've won the first place this time!"

Lin Ping smiled and didn't speak, this kid is pretending to be a good one-handed, but it's a pity that he doesn't know that there are people outside the sky, in terms of academic ability, Liu Xiangqian is really difficult to pass Wang Yige.

"Teacher!" At this time, Liu Qingmei behind her tugged at Lin Ping's clothes.

"Huh?" Lin Ping turned around.

"Did you copy this test paper by hand?" asked Liu Qingmei in a low voice.

"Yes, I gave it to you, and then Teacher Ma and I copied these copies overnight last night for everyone to use for the exam. ”

Lin Ping said with a little pride, this is indeed a thing to be proud of.

"Thank you, teacher. Liu Qingmei whispered.

Lin Ping was stunned for a moment, and then Wang Yige also said, "Thank you, teacher!"

The other four children shouted, "Thank you, teacher!"

Lin Ping's heart warmed, and he pretended not to care and said, "Hey, it's okay, you guys are doing a good job is the greatest thank you to me and Teacher Ma." ”
