After deciding to find an opportunity to try the acupoints and pulse interception to see if they could succeed, Lin Xu continued to look through the biology textbook. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The last chapter of the human body unit of the biology textbook introduces the urinary, endocrine and reproductive systems of the human body, and Lin Xu couldn't help but widen his eyes as soon as he turned it, because the drawings of this chapter actually drew the structural diagrams of the male and female lower body reproductive systems. Although it was only a simple composition in black and white, there was no subtlety and beauty at all, but it still made Lin Xu's eyes widen and gave him a great impact.

Although he knew that men's bodies were different from women's bodies since he was a child, he didn't understand them when he was a child, and he didn't pay much attention to them at all. It wasn't until after entering puberty, because of the growth and development of the body, that physical and psychological changes began to begin, and I began to be curious about women's bodies, and began to pay attention to the women around me.

But curiosity and attention are the same thing, but no woman will take off her clothes to show him carefully. In this era, there would not be such restrictive footage on television, not even the plot of the woman taking a bath, anyway, there was no TV station that could be received in their village. And he has not yet come into contact with restricted films, books, pictorials and the like. So although he knows that the structure of a woman's body is different, in addition to the obvious protrusion on the girl's chest that can be seen in the upper body, he also knows nothing about the difference in the structure of the lower body, and he is not clear at all.

It wasn't until this time, after reading the illustrations in the biology textbook, that he understood. Although this illustration is simple and crude, there are many places that should be depicted, and they are also marked in the way that the lines are drawn indicated, such as the yin 'canal', the ovaries, the sub-uterus, the fallopian tubes, and so on.

After reading it, Lin Xu couldn't help but subconsciously glanced at the girl closest to him, Zhang Yuwei at the same table, and also aimed at the lower body of others.

may also be Zhang Yuwei's sensitivity, and immediately noticed his different gaze. Turning her head to look over, she still had a strange inquiry in her eyes at first, but when her eyes swept over the illustrations in the biology textbook that Lin Xu was looking at on his desk, she immediately understood. This understanding couldn't help but immediately blush.

"What are you looking at?" In shame, Zhang Yuwei reached over, turned Lin Xu's biology textbook over and closed it, and then immediately turned her head over and looked down at the book. It's just that the blush on his face couldn't dissipate for a long time, and he felt that Lin Xu's eyes were also hot at this time, and he didn't dare to look at each other at all.

Seeing that he was discovered by Zhang Yuwei, Lin Xu couldn't help but blush with embarrassment. I wanted to explain, but I didn't know what to say. opened his mouth, but he had to smile and shut up, and didn't say much.

After turning his head, he silently turned the biology textbook to the previous page and looked at it again.

Zhang Yuwei caught a glimpse of Lin Xu turning his head out of the corner of her eye, and she breathed a sigh of relief. But when he noticed that Lin Xu opened the biology textbook to read it again, he couldn't help but feel angry. But this time, he didn't reach over again and closed Lin Xu's book again. After all, people are reading their textbooks, and she really has no reason to interfere too much, as long as Lin Xu doesn't turn around and stare at her again.

"What kind of biology book is this, how can there be such a thing?" sighed in her heart, but Zhang Yuwei couldn't help but be curious, and secretly found her biology textbook. Then he supported his head with his arms, isolated Lin Xu's gaze, and went to look secretly. She was sitting against the wall, as long as she blocked the gaze of Lin Xu at the same table, she was not afraid of being seen.

Adolescent children will begin to be curious about the body of the opposite sex. Not only are boys curious about girls, but girls are also curious about boys.

In addition to introducing the differences between male and female reproductive structures, this article also gives a brief introduction to the functions of each part of the reproductive system. It also briefly introduces how men and women give birth to children. That is, the sperm produced by the man and the egg produced by the woman meet and combine to become a fertilized egg, which then develops into an embryo, and then grows into a newborn baby after the woman's October pregnancy.

It's just like that, but it's just a very simple general introduction, and there is no detailed process. First of all, it is not explained how a man's sperm and a woman's egg can meet. So after Lin Xu read it, he still didn't understand it very well, but he mainly studied the different body structures of women.

After this article on the reproductive system, there is also a special article on the physical changes of puberty. The laryngeal segment of the boy protrudes and begins to change voice, the girl's mammary begins to develop and enlarge, and the function of the nervous system and the heart and lungs and other organs is significantly enhanced. There is also the rapid development and maturation of the sexual organs, with dreams in boys and menstruation in girls.

From this article, Lin Xu learned more about the differences between the changes in the bodies of men and women. However, the boy's dream relics mentioned in it, because he has not experienced it, he doesn't quite understand what a dream is called.

After reading it, although Lin Xu understood some things that he didn't understand before, he also gave birth to more curiosity and questions. But the explanation of these things in the book is only general, not more in-depth.

He can only look forward to it with a little regret, hoping that the biology class can get to this part of the content as soon as possible, and the biology teacher will talk about it more. But I vaguely feel that this seems to involve some private matters, and I am afraid that the teacher will not talk much about it in class.

After roughly reading the biology textbook, Lin Xu continued to look at other textbooks, but before he finished reading the language, the bell for the end of the morning reading had already sounded. The morning reading class is only half an hour, but it is shorter than the 45 minutes of a normal class.

After the morning reading class, it is time for breakfast, and then after breakfast, at 8:10 a.m., the first class of the morning will begin. It was 7:30 a.m., forty minutes before the first class in the morning. Lin Xu planned to take advantage of this time to find a place where no one was to take time to practice his red sand hand and spinning Qiankun palm.

When he practiced at home during the holidays, it took him about an hour just to practice the red sand hand. However, with the proficiency of later practice and the increase of physical strength, the time for him to practice these two martial arts was correspondingly shortened. By the time school started, he had been able to cut the practice of both subjects to less than an hour.

However, forty minutes, in addition to practicing, also have to eat, I'm afraid it's a bit insufficient. After thinking about it, Lin Xu decided that if he didn't have enough time, he would only practice the red sand hand, and rotate the Qiankun palm to practice the rest of the time.

Thinking like this, as soon as the bell rang after class, he quickly packed up the books on the desk and stuffed them into the drawer, and stopped carrying his school bag. After cleaning up, he quickly got up, and without waiting to be with his roommates in the same dormitory, he ran out first, went downstairs and turned onto the main road, and went straight to the back playground.

He left so quickly, but it also made Zhang Yuwei next to her breathe a sigh of relief, she was still a little shy and embarrassed at this time, and she was afraid of saying more to Lin Xu and taking more pictures.
