Tiancheng ran out of Lao Mu's house and went straight to his breeding farm, Lao Zhao saw Tiancheng's arrival, as if he saw a savior.

"Quick, our sow has a cub again!" It was a very common thing, but for Lao Zhao, he didn't dare to do it by himself, all Tiancheng watched it himself, for Tiancheng, every sow in the breeding farm touched his nerves, and every sow gave birth, never dared to take it lightly, which was the lifeblood of the breeding farm.

Tiancheng was running very quickly, and as soon as he stopped, he stood there panting heavily, really out of breath, and asked Lao Zhao intermittently: "Is it a smooth delivery?"

"Hmm. Lao Zhao coughed and replied heavily.

"That's okay!" Tiancheng's heart was put in his belly, and when he saw the sow in the farrowing room who was giving birth, he breathed a sigh of relief, a bunch of cubs under the sow were feeding, and Mu Zhen was staring curiously there.

It was another litter of black and translucent piglets, Tiancheng's face showed joy, and he called happily: "Mu Zhen, come here!"

Mu Zhen raised her head suddenly when she heard this, and followed Tiancheng out of the delivery room.

"I came from your house just now, and your father said that he wanted you to go home and wouldn't let you do it!" Tiancheng said, took out five ten-yuan bills from his pocket, handed them to Mu Zhen and said: "You have been here for so many days, and I won't give you any other things, this fifty yuan, you take it to buy some school supplies, and it is also a little bit of uncle's heart!"

Mu Zhen didn't take it, he felt that his father asked him to come, which was no different from cutting grass for the cattle back then, but the way he punished him was different, and he didn't do any work here, how could he take Uncle Tiancheng's money?

"Thank you, uncle, I can't ask for this money, I have a very happy time here, how can I ask for your money?" Mu Zhen said sincerely.

"This has nothing to do with whether you are happy or not, you are here to help, how can I not show a little heart? Besides, you see that the sow has given birth again, this is a happy event, and it is also a happy money to give you some money!" Tiancheng said, putting the money directly into Mu Zhen's hand, and casually urged: "Take it quickly, if you don't take it, uncle is going to be angry!"

Mu Zhen saw Tiancheng's somewhat angry expression, reluctantly took the money, and whispered, "Thank you, uncle!"

When Mu Zhen returned home, the sun had already slipped to the top of the West Mountain, and Mu Yan, who was preparing dinner in the kitchen, saw her brother coming back and said hello: "Brother, come and help me make the pot." ”

Mu Zhen didn't say a word, went directly into the kitchen, picked up a large handful of firewood in front of the pot door and stuffed it into the bottom of the pot, the fire at the bottom of the pot was immediately extinguished by this firewood, and immediately poured a thick smoke, choking the two of them kept coughing, Mu Yan smiled: "Haven't you learned to cook a pot in the pig farm?"

"It's not to learn how to cook a pot there, how can I learn it, besides, I'm going there to exercise my hands and feet, and see how I blow it!" After speaking, one hand picked up the firewood with a burning stick, and then lay on the ground and blew on the curtain of the pot door.

It's really strange to say that this ember encountered Mu Zhen's blowing, and suddenly there was a "boom", and Xiongxiong burned.

"It seems that I still learned, I deliberately choked me with a cigarette just now!" Mu Yan, who was standing in front of the pot with a shovel, joked with a smile.

"How can I be willing to choke you? You are alone at home, what about them?" Mu Zhen was referring to, of course, his parents and Mu Bao.

"Don't dare, Mu Bao followed him to the ground, they should come back in a while, let's hurry up and cook, and wait for dinner!" Mu Yan replied as she kept turning over the dishes in the pot with a shovel.

"When I came just now, Uncle Tiancheng gave me fifty yuan, and he took it out as he spoke!" Mu Zhen said a little happily.

"Why do you give so much?" Mu Yan was a little surprised.

"That's it, I didn't think of asking for money when I went there to help!Uncle Tiancheng has to give it to us, let's not make him angry!" Mu Zhen said and put it back in his pocket.

As the two were talking, Lao Mu and Xiuhua entered the courtyard gate, and Mu Bao jumped to the kitchen with a few small fish strung with dogtail grass.

"Look at the fish I caught, you can make fish soup!" Mu Bao said happily to Mu Zhen and Mu Yan.

"It's almost the same to feed the ducks!" Mu Yan said in a slightly mocking tone.

"Do you think that's it, we still have it there!" Mu Bao said, pointing to Lao Mu outside the house, Mu Yan looked back, sure enough, Lao Mu was holding several strings of these small fish in his hand, and was about to find a basin to put down!

The family quickly cleaned the fish, fried it in oil, and then cooked a pot of delicious fish soup.

After dinner, Mu Yan and Mu Bao followed Xiuhua to the side of the road to cool off, leaving Lao Mu and Mu Zhen at home, Lao Mu took out a few exercise books purchased from the bookstore this morning, and said to Mu Zhen: "The recent education reform, I am making a plan, the state advocates that students should start from reading, writing, listening, speaking, and practicing, and do a good job in classroom teaching.

Mu Zhen understood that Lao Mu was going to impose the teaching of primary school on himself again, he looked at the stack of books, and did not say a word, even if he was dissatisfied, what could he do? Who let himself not get satisfactory results in this exam? Mu Zhen silently complained to himself.

"I've carefully selected these books from the bookstore, and you'll have to master them. Lao Mu emphasized again and again that he was afraid that Mu Zhen would be lazy.

Mu Zhen took the books, and then went back to his own book next door to the kitchen, he knew that Lao Mu's idea was to let him rehearse these exercises from now on, from tonight, without leaving the book, this is the teaching reform in Lao Mu's heart. But education reform in the heart of Lao Mu is another idea, he has more than once believed that education is to give full play to the subjective initiative of students, classroom teaching is to let students become the protagonist, the teacher becomes a supporting role, how to guide students to understand the knowledge to be taught in the classroom is fundamental, and there is this kind of education in the guidance of Mu Zhen, always deviate from his own teaching philosophy, engage in special tactics, in his eyes, for his son, is to practice more, practice makes perfect is common sense.

Since then, Mu Zhen has never gone out of the door, every day in the room during the day to read the few exercises that Lao Mu bought, as soon as Lao Mu has free time, he will sit down to check Mu Zhen's learning, or choose the unit test in the book to test Mu Zhen.

In Mu Zhen's view, those questions are similar, and then deliberately practice, it is tantamount to doing useless work, even so, Mu Zhen is not willing to raise objections to Lao Mu, he is worried about triggering Lao Mu's endless nagging, worried that Lao Mu will be stimulated, and cause his anger, worried that Lao Mu will misunderstand his learning.

Mu Zhen's worries were not superfluous at all. Mu Zhen always feels that the important thing in mathematics is the mastery of formulas and theorems, and mastering those basic formulas and theorems will lay a solid foundation, just like building a foundation for a house, formulas and theorems are the foundation, and the exercises are as simple as building a house and bricks on it.

Mu Zhen had never encountered any problems, but the truth was not as he thought, and there was a problem in this exercise set that he could not overcome, and when he looked at the answer, the answer was as simple as a few words—using the method of counterproof. The teacher may have talked about the counter-evidence method in the last month, but because of the depressing days in the later period, the class could not concentrate at all, so listening to the lecture was "to the ear", and the knowledge that the teacher talked about entered from the left ear and slipped away from the right ear, without putting a few words in his mind, and the textbook did not talk about the special proof method of the counter-evidence method, Mu Zhen felt at a loss.

At lunchtime, Lao Mu came back, Mu Zhen took this question to ask Lao Mu, Lao Mu looked at it for a long time, his brows were furrowed, and he didn't know where to start, he suddenly remembered Yuan Bing, who was admitted to the mathematics department of the teacher college in the neighboring village last year, and he should have a way to solve this problem.

"I can't prove this counter-evidence method either, so I'm going to ask Yuan Bing from the neighboring village in the afternoon. Lao Mu said without digression.

Although Yuan Bing's home is in Li Ji, which is adjacent to Xiaowangzhuang Village, but the responsibility of the family is only separated by a ditch from the responsibility of Lao Mu's family, when he usually works, Lao Mu sits on the ground to rest, as long as he meets Yuan Bing's father, the two will sit on the ground and chat for a while, Yuan Bing's father is the accountant of Li Ji Village, and he is also a capable person in the village, Lao Mu admires him very much, especially after his son was admitted to college, Lao Mu is even more impressed by Yuan Bing's father.

In the afternoon of the same day, Lao Mu went to the plot of land next to Yuan Bing's house, and while working in the field, he looked in the direction of Li Ji Village from time to time.

Looking up at the sun's distant treetops, Lao Mu felt that there was no hope of waiting for the arrival of Yuan Bing's father and son today, so he decided to abandon the work in his hand and take his son to Li Ji to visit this top student of the mathematics department. Thinking of this, Lao Mu didn't have the heart to work in the field, but walked up directly from the rice field, he didn't care about washing the sludge on his feet, he only hastily packed up his things, and went straight home, Xiuhua looked at his back and let out a long sigh.

Lao Mu, who returned home, didn't say a word, and directly pushed out his old Long March, beckoned Mu Zhen to take the math workbook and went to Li Ji together.

Liji Village is not big, there are about 200 people, Yuan Bing's family lives in the village, and Lao Mu found the door of the house after a little inquiry.

"Big brother, which gust of wind blew you here!" Seeing Lao Mu who pushed open the gate and entered the courtyard, Yuan Bing's father greeted Lao Mu in surprise.

"It's so close, come to your house to knock on the door, is Yuan Bing at home?" asked Lao Mu.

Before Yuan Bing's father could speak, he heard Lao Mu calling his name in the house, so he got up and stood at the door of the room to greet Lao Mu: "Uncle Mu, I'm at home!"

"It just so happens that my son has a math problem and wants to ask you for advice, so I brought him to your door!" said Lao Mu politely.

"Look at what you said, it's really polite, as long as you can help, you will definitely help!" Yuan Bing felt that Lao Mu was a little embarrassed to say this.

"Take it out and let your brother take a look!" said to Mu Zhen, who was standing behind the bicycle.

Mu Zhen didn't speak, she took out the workbook directly, and turned out the question that folded the pages directly.

Yuan Bing glanced at it, smiled and said: "This question is a traditional question, to put it bluntly, he won't take the test at all, it just exists as a proof method, and this proof method is rarely used, it seems useless for you to let him do this?"

Lao Mu heard Yuan Bing say this, his face was a little embarrassed, and he didn't know what to say.

Lao Mu's discomfort has attracted Yuan Bing's attention, and he feels that Lao Mu may not understand what he said, and explained: "I'm not saying that you can't do it, but if you do it, you don't necessarily add much knowledge, this question is a bit difficult to say, I write it down to prove the process, you let him understand it well, see if he can understand it." ”

As he spoke, he took out paper and pen from the drawer of the table, and after a while, he wrote down the proof process completely, handed it to Mu Zhen, and said: "See if you can understand it, there are very few such questions, and I have only touched three or two questions, if you understand, I don't need to explain!"

Mu Zhen looked at the proof process carefully, nodded, and said that it was now solved, Lao Mu watched Yuan Bing solve the problem so quickly, and showed a friendly smile: "Thank you!"

"Neighbors, how can you be so polite!" Yuan Bing's father hurriedly replied.

On the way back, Lao Mu pondered Yuan Bing's words: "It's useless! Could it be that I'm wrong? If I don't encounter this kind of problem, will I still take Zhen'er to seek a teacher? Students should practice more, this must be not wrong, he is a young man, and he still doesn't know enough." Lao Mu still insists on his own point of view, learning is to practice more, and there is no room for ambiguity.

In Lao Mu's insistence, Mu Zhen's life has not been able to get rid of the shadow of the sea of questions, and she still insists on repeating the same learning every day, and she is a little tired.
