Ji Zhouzi went to his parents' room first and sat by the bed to watch his younger brother who was sleeping peacefully.

Ji Zhouzi looked at his younger brother seriously. Ji Xiuzhu didn't look much like her. She looked more like her father and Xiao Zhuzi looked more like her mother.

But in terms of skin color, she has been fair since she was a child, and her younger brother has been a little black charcoal since she was born.

She grew older and neither knew how to take care of her skin nor maintenance. Later, she became more and more tanned. When she came out to work, she bought some Meijiajing for use because she was short of money, so that her skin condition was the same as in her thirties.

The younger brother later laughed and said that when the two siblings went out together, she was like the elders of her parents, causing her to beat her up.

"Stupid boy..." Ji Zhouzi gently put his brother's little hand into the quilt, his eyes soft, "It's great, my sister will definitely remember your growth experience in this life."

After watching his younger brother quietly for a while, Ji Zhouzi gently left the bed, walked to a desk in the corner of the room and sat down, and took out the homework he brought back from his schoolbag.

When Ji Zhouzi took out his homework, 666 was unwilling to come out lonely: [Host, there is a measure of the top students, which is the result, which is also the easiest way for you to earn achievement values ​​at this stage.]

666's tone is extremely tempting. It cannot make the host fall into its reputation. Since it is a system of top students, how can it have poor grades?

No, it will never allow its host to embarrass it.

Ji Zhouzi paused, squinted his eyes, and asked it seriously in his heart: [How many points do you need to get the achievement value?]

666 is so happy, it can’t wait to tell the host: [As long as you get the first grade, you will have the most achievements.]

[For example, if you have the first grade in each subject, your achievements will be worth 1 point.

The first place in each subject is in the year, and each achievement is worth 2 points.

The first place in the city in each subject, and each achieves 3 points.

The first place in the province in each subject, and each achieves 4 points.

He scored first in all subjects in the country, and his achievements were worth 5 points each.

The total score is the first in the class, the achievement is worth 5 points. The first in the grade is worth 10 points. The first in the county is worth 20 points. The first in the city is worth 30 points. The first in the province is worth 100 points.]

[Host, calculate, you are now in the second grade of junior high school, and there are 8 subjects in total. Assuming that you are the first in the class in each subject and the first in total score, you can easily get 13 points. If the total scores of each subject are the first in the whole grade, you can get 26 points. Look, is this achievement value very easy to get?]

Ji Zhouzi was excited. She was in the second year of junior high school. There were many exams in the future. She was reborn again. Wouldn’t the junior high school exam be easy for her? It is not difficult to get the first place. As long as you get the first place, you still have to worry about not being able to exchange your health value?

Ji Zhouzi confidently opened the physics paper, and when his eyes fell on the topic, he suddenly condensed.
