The teacher is polite to you, can you still pretend to be forced? Of course not.

Liu Sen still learned a lot from his father.

"Mr. Lin is very comprehensive, I don't have anything to add. ”

After coming and going, Lin Han's attitude towards Liu Sen changed greatly, and even began to have some energy coming uninterruptedly, obviously appreciative.

After three weeks of training, Liu Sen tried his best to obtain spiritual power, and finally mastered the differential median theorem, indefinite integral, definite integral, derivative, differential equation, multivariate function differentiation, multivariate function integration, curve integration, surface division, infinite series, preliminary complex variable function, and differential geometry foundation.

The strength is roughly equivalent to the level of a perfect score in the freshman year of the Department of Mathematics.

It consumed 29,800 spiritual power, "Linear Algebra and Spatial Analytic Geometry" was also done, mathematics still has not been upgraded to level II, and "Probability Theory and Mathematical Statistics" is still missing, but this book does not contain much content, and with the previous foundation, the consumption of spiritual power will be reduced, even so, it still requires nearly 10,000 spiritual power.

Liu Sen is indeed a perfectionist, a little uncomfortable if he doesn't get to the full level, and he always thinks about how to get the "Theory of Probability" right.

While improving, Liu Sen regretted that it was too bad to participate in the Provincial Mathematics League, and all the spiritual power he earned was consumed.

Although he complained in his heart, he also understood that, as the system suggested, mathematics is the foundation of all academics, and sooner or later it must be improved step by step, and the sooner it is promoted to level II, the better it will be.

I was going to Feicheng to participate in the Hui Provincial Mathematics League, the location was at the Hui Provincial Normal University, because Gyeongju to Feicheng was two hours away, the school arranged for the bus to go to Feicheng one day in advance, and stayed at the nearest Normal University Hotel.

Jiang Xue deliberately came over and said to Liu Sen, "Brother Sen, I wish you, the sea is wide and the fish can jump, and the sky is high and the birds can fly." ”

"It's really sour, it's not just a provincial league exam. ”

Jiang Xue pursed her lips and smiled slightly, "Wait for you to come back." ”

Her face was calm.

Liu Sen received her mood fluctuations from the system, which were very violent, a full 100 points, this girl has a high emotional intelligence, and it is really rare to have this emotion.

"When you come back, you can continue to lecture on the topic for me, and there has been no progress in this time. ”

"Okay, I'll give you three questions a day. ”

"Thank you, Brother Sen. Jiang Xue is very happy, she is a girl with strong self-control and very clear goals, and at this stage, she is studying well and entering a good university.

Liu Sen is too lacking in spiritual power now, and when he saw Qiao Yu standing on the balcony, he also stood over, and the two looked at the scenery downstairs side by side, as well as the pedestrians walking around.

Qiao Yu frowned, feeling 50 points of disgust.

Haha, yes, there were several mood swings in the morning, far more violent than usual, and Liu Sen naturally couldn't let go of the opportunity.

"I left for Feicheng in the afternoon. ”

Liu Sen said.

"I wish you success. Qiao Yu still remained polite.

"I definitely want to win a provincial first prize this time, at least a few points can be added to the college entrance examination. ”

Qiao Yu smiled reluctantly, and scolded in his heart, you just dream.

Provides another 100 energy.

"Enter the provincial team, enter the national team, and then come back with a gold medal, and directly send it to a prestigious school. Liu Sen said, "However, I will still come back and encourage you to work hard for the college entrance examination." ”

Qiao Yu was furious in his heart, you still have to be a little embarrassed, you really dare to think that if you send it, you will come back disgusting, bah, it is impossible to escort it.

This provides 200 energy.

"Tsk, don't envy me, and don't be jealous. ”

Nima, Qiao Yu's face froze, and he couldn't wait to deduct Liu Sen's smile from his face.

400 points arrived, Liu Sen was satisfied.

At noon, Liu Dahai called his son, and Liu Sen also had to go home to pack two clothes.

Liu Dahai waited at home and directly threw away 5,000 yuan.

"It's better to go out than at home, don't hold back, take it. ”

Liu Sen took a thousand from it, and handed the rest to his father, "This trip to Feicheng, the school will take care of food and housing, and I will come back tomorrow after the exam, there is no cost, and there is no time to spend." ”

Although his parents can make some money, it is definitely hard money, in the past, Liu Sen would think of ways to ask for more pocket money, but now he is all about spiritual power, and the things he can buy are absolutely good, and he looks down on money a lot.

Liu Dahai is relieved, his son has really grown up and is sensible, look at it, he doesn't want any money in hand.

"Good son, work hard to get to Jianghai University, my father will also buy you a room at the school gate, and your mother and I will always repay the loan. ”

Liu Dahai's biggest ambition is that his son will gain a foothold in the big city of Jianghai, and every time he sends food to Jianghai to live in his son's house, that is the greatest happiness, so his grandson was born in the big city and has a firm foothold.

Liu Sen felt a warm current in his heart, his parents were the kind of people who were dedicated to thinking about their children, and he was really ignorant before.

"In the future, I just need to find a girlfriend who has a house. ”

"That's not a big deal, absolutely not, your uncle's family is a daughter, and our old Liu family is the only one ...... you."

Liu Sen thought to himself, I can eat soft rice and hard food, hurry up and let my father stop, otherwise I will be trained again.

After lunch.

8 people got on the bus, Lin Han accompanied him, said some discipline on the way, stay in the hotel honestly at night, don't run around, set an alarm clock early tomorrow morning, etc.

Lin Han's impression of Liu Sen has changed greatly, and he is extremely looking forward to his breakthrough.

In the past two years, the competition between Feicheng No. 168 Middle School and Feicheng No. 1 Middle School has become increasingly fierce, and everyone wants to become the best high school in Hui Province.

These high school super scholars, the top 100 in the province, absolutely none of them die to study, they are all versatile, have excellent IQs, and have mastered the ultimate method of learning and the god-level skills of the exam.

As long as this kind of talent is gradually accumulated, in a few years, it will gradually widen the gap and become the first high school in Huizhou Province worthy of the name.

The math league has always had the largest number of students, and it is a battle.

The two high schools have long started training players, almost accounting for 95% of the players in the provincial team every year, and only one or two are won by other municipal high school students, and most of them are at the bottom.

Along.

Liu Sen's egg hurts, and he is still close to being able to get the second level of mathematics with nearly ten thousand spiritual powers, and if he doesn't upgrade perfectly, he can't guarantee a full score, and now he is really uncomfortable if he doesn't get a full score.

Using spiritual power to solve problems is always not beautiful, and the opportunity to improve the self-confidence coefficient is lost.

After staying in the hotel, he couldn't stay idle, wandered around the Huizhou Normal University, and went to the mathematics department to see if he could find an opportunity to pretend to have some spiritual power.

I didn't pay attention to it, I hit someone all of a sudden, it was a special feeling, a little slippery and a little soft, and it was concave inside, how could it be so comfortable.

It was a scream.
