Lei Xiaochen originally had five merit values ​​and two karma values, plus a little merit value and a little karma value collected by the cross today. He had a total of six merit values ​​and three karma values.

Today he has prayed three times, using two points of merit and one point of karma. He now has 4 points of merit and two points of karma available.

The college entrance examination is about 20 days away. His most important thing at the moment is to improve his grades and strive to make a big splash during the college entrance examination.

Lei Xiaochen's first and second model scores are around 500 points. If he is lucky in the college entrance examination, he may be able to pass the first-class line.

Previously, the greatest hope of his family and himself was to be able to enter the first-book line. His father Lei Zhiwei promised early that as long as his grades could be ranked first, he would buy him a high-end mobile phone as a reward. His sister Lei Yuyi might promise. If his scores were ranked first, he would definitely buy him a high-end laptop.

In the past, Lei Xiaochen did not have the confidence to get rewards from his father and sister, so his strength was just like this. It was difficult to improve in such a short time. Can his college entrance examination scores be finally on the first-tier line? He felt that the proportion of luck was more important than strength.

Now that he has learned the magical prayer technique, the goals of the college entrance examination naturally need to be improved a lot. The minimum goal he sets for himself now must be 985 universities.

He did not directly target Mizuki and Kyoto University because he did not know what the scores in comprehensive science and English were this time.

If the scores of these two subjects are high enough, he will be sure to target Shuimu and Kyoto University. Whether he can achieve this goal is nothing more than the gap between five merit points.

Now there are still about 20 days before the college entrance examination. He can still get twenty merit points through the cross, and it is very easy to reserve five merit points.

He was able to enter the highest institution of learning in China by spending five points of merit. This was once something Lei Xiaochen dreamed of. Now he had the opportunity to enter the university he dreamed of, of course he was very happy, but he was not prepared to use this method.

In Lei Xiaochen's opinion, it is too wasteful to use a little merit to exchange for good results in an exam. There are countless exams in his life, and it will be meaningless to do this in the long run.

Only by truly improving grades is the way to go.

He is planning to spend more merit points to improve his memory and IQ. As long as his memory and IQ improve, his test scores will naturally be improved.

This is the correct way to open the prayer technique to learn!

Now that you have made a decision, the next step is to try it.

He first spent a little merit value to improve his memory. After praying, Lei Xiaochen took out a book to start reading. After reading a page, he began to recall.

What made him happy was that although he had not yet reached the level of not being able to remember everything he had just read, he could basically remember what he had read and repeat it again, but it was just a little different in details.

What made him even more happy was that as long as he recalled the various books he had read before, the general content could be recalled basically.

The effect of the merit value is even greater than he imagined. A little merit value has greatly improved his memory. If he is willing to spend 10:8, he can sooner or later increase his memory to the level of never forgetting everything.

The effect of memory improvement is so obvious, Lei Xiaochen believes that the effect of improving IQ is definitely not much worse.

Lei Xiaochen began to pray again, praying that his IQ could be improved. After the prayer, his merit value was reduced a little again. Now he only has two merit values ​​and two karma values.

After the prayer was over, Lei Xiaochen was sure that his IQ had been improved to a certain extent, but to what extent? He was not clear about it, and could only test it through practice.

In yesterday's math exam, Lei Xiaochen had not done several questions. Now his memory has been greatly improved. He can clearly recall the questions he did not do.

One of the questions is as follows:

The known function f  (x  )=a  e  x  .

(1) If the tangent line of the image of function f  (x  ) passes through the point (0,-1), find the value of a  ;

(2) Is there a negative integer a ? Make the maximum value of function f (x  ) a positive value? If it exists, find the values ​​of all negative integer a  ; if it does not exist, please explain the reason.

This problem of function and derivative is quite difficult, and it can be used to test how much its IQ has improved?

After recalling this question again and thinking about it for a while, Lei Xiaochen quickly had a way to understand the question.

Picking up the pen, Lei Xiaochen began to write on the manuscript paper, and soon came up with a =-1e. The following proof is very difficult, but Lei Xiaochen already has a clear idea. If he writes with great pleasure, he will finish the answer soon.

Through the answer to this question, Lei Xiaochen has been convinced that his IQ has indeed improved to a certain extent. However, it is difficult to have a quantitative data as much as it has improved.

After praying twice in succession, his memory and IQ have been significantly improved. Lei Xiaochen was greatly encouraged. He planned to use all the merit points he had accumulated in recent days to improve his memory and IQ.

He had a premonition that by the day when the college entrance examination began, perhaps he could be admitted to the highest institution in China with his true strength.

After improving his memory and IQ, Lei Xiaochen suddenly had the motivation to learn. He found the math wrong question book and began to overcome the first question.

Before I knew it, it was getting dark. By the time my parents came in, Lei Xiaochen had already overcome a large part of the difficult problems in the wrong question book.

"Chen Chen, are you still studying? Come and see what delicious food mom brings you?" Xie Lan shouted loudly as soon as she entered the door.

Lei Xiaochen was interrupted by his thoughts, so he simply put down his pen and went out to greet him.

"Ah, such a big prawn! How much does it cost per pound?" Lei Xiaochen took the bag in his mother's hand, looked inside, and exclaimed in surprise.

"It's not very expensive, 75 per kilogram. Today I've finished the third mock exam. I'll celebrate it for you." Xie Lan said happily.

Taking off his coat and changing into slippers, Xie Lan asked around the bush: "Is it difficult to have a third-model model? I feel that your grades have improved this time?"

"Without any progress, you have to know after the grades are given. You ask about your grades every day, so don't put pressure on your children?" Lei Zhiwei directly interrupted Xie Lan's question.

Xie Lan glared at her husband and retorted: "I took Chinese and math exams yesterday. I was afraid that the child would be under pressure, so I didn't ask for it all day. Today, I have finished all subjects, so I can't ask yet?"
