"Anyway, that's it, you can choose for yourself two ways." Song Xinying also wrote down the two solution steps in detail in her notes while explaining, but when she raised her head after finishing the question, she still saw a few big faces full of doubts.

The room was quiet, and Song Xinying's voice was already extremely clear, and even the slight breathing could be heard clearly. According to her understanding of the people in front of her, even if they didn't hear part of the problem-solving process, they wouldn't know how to do it at all, and they could do it if they thought about it carefully. But now they look like they don't understand and want to listen to it again, this abnormal situation is something that Song Xinying never expected.

The puzzled expressions on the faces of several students seemed to be frozen by glue, and they did not change for a long time. Among them, there was a tall and thin boy who was still staring at Song Xinying, and his eyeballs began to run in his sockets with the subtle changes in Song Xinying's demeanor and demeanor.

"Ahh Song Xinying's expression gradually frightened, when she saw the classmate whose eyes were rolling, Song Xinying was frightened and screamed, she hurriedly got up from the chair and staggered back to the door in a few steps. But as soon as she finished screaming, the rest of the room woke up from the strange state just now.

"Song Xinying, what's wrong with you?" In the eyes of everyone, it was Song Xinying who was about to open the door and escape.

"You...... You guys...... Don't remember? Your expressions were so scary just now! ”

"Huh? Have it? Several people looked at each other, but apart from laughing at each other's grimaces, they didn't feel anything scary.

"Haha, Sister Xinying has always been so timid, maybe the classroom is too quiet after dark, so she will be frightened by our usual behavior, right?"

"This ...... I....... But! Song Xinying wanted to defend herself, but seeing that everyone else didn't remember what happened just now, who would believe her when she said it? And now the state of her classmates is no different from usual, and she even wonders if she was frightened by the content of the previous association and hallucinated.

While thinking about these things, Song Xinying's body unconsciously sat back in her previous seat.

"Hey, hey, hey...... Sister Xinying...... See if you can ......" One of the fatter little boys smiled embarrassedly at Song Xinying, he was actually listening to what Song Xinying said just now, but he was confused when he listened to it. When he was still in the first half of the problem-solving step, Song Xinying was almost finished talking about the second method of solving the problem.

The slightly chubby boy in front of him was probably stunned during the explanation just now, so he couldn't keep up with his train of thought.

"Uh...... I didn't know what was going on just now, and I was stunned. The girl with the ponytail was also a little embarrassed, she had been following Song Xinying's solution ideas just now, and she had already understood how to do this fill-in-the-blank question, but at a certain moment, the originally clear ideas suddenly became extremely blurred.

The rest of the classmates who were not close to Song Xinying did not say a word, looking forward to Song Xinying's answer again.

Hearing the voices of her classmates' questions, Song Xinying realized that she had re-seated herself in her previous position at some point. She was so frightened that she tried to get up from her seat, but her legs suddenly went limp, and she couldn't use any strength at all, and she couldn't stand up at all.

"What's wrong with me?" Song Xinying only felt cold sweat all over her body, and her whole body trembled uncontrollably, she had felt this feeling before, and more than once.

She only remembered that this feeling would only appear when she was on the verge of death, but now that the few classmates in front of her no longer had the previous abnormal state, and there was no abnormal sound in the classroom, why did she linger in this sense of fear that she only had when she was facing death?

"Xinying, what's wrong with you?" The girl with the ponytail hurriedly held Song Xinying's hand supporting the table, she only felt that Song Xinying's hand was cold.

"Che, don't you want to waste time telling us about it again? It's stingy. ”

"No, it's not, I'll talk about it."

Song Xinying held back the fear in her heart, forced herself to forget her previous associations, and calmed down her mood, so that she could give a lecture to her classmates. Those who can study in a classroom with themselves must be classmates who get along well, Song Xinying is afraid that she will say the wrong thing and force these few friends away, this time she hopes that her classmates can understand.

"Let's talk about a relatively simple method first, first establish a spatial Cartesian coordinate system......"

"Hey, wait a minute, and build a coordinate system? This is a fill-in-the-blank question, and it will take enough time to do a big problem according to the method you are talking about now, so what is the use of us learning it? Don't waste our time here, let's talk about another way! The chubby boy interrupted Song Xinying's explanation a little impatiently, with this simple and basic method, he would definitely be able to do it without explanation. This, of course, he himself thinks.

"Qiangtao! I said can you be quieter, you don't want to listen to other people who want to listen, and besides, haven't you already listened to the advanced way of solving the problem just now and still don't understand? Then we naturally have to master this simple and complicated method of solving the problem first. ”

"Cut, nosy, I just accidentally got stunned. Well, if you want to hear this, then listen to it first! The chubby boy named Qiang Tao plucked his ears disdainfully, and then he sat sideways and stopped listening to Song Xinying's explanation.

"Ru Fan, don't be angry, maybe I didn't think it through, otherwise let's talk about another method first." Song Xinying was afraid that the two would fight, so she hurriedly persuaded to fight, most of the persuasion methods she knew were to take the mistake on herself, this persuasion method was still taught by her classmates in the class at the beginning, and the effect was very good in normal times. But in this classroom, this way of persuasion provoked Ru Fan.

"Smack!" The loud sound of slapping the table sounded in this soundproofed classroom, and when she heard Song Xinying take the responsibility on herself, the ponytail on the back of Ru Fan's head was angry and floated up, and this loud noise was also made by her. "The surname is strong, don't be ignorant, it's good that Song Xinying is kind enough to give you a lecture, don't kick your nose and face here, if you really have the ability, go to the next classroom to figure it out by yourself!"

Qiang Tao's face was flushed by this sentence, and his slightly chubby figure looked like he was fatter than before, as if the bulging place of his body was swelled by the anger in his heart.

He didn't expect Ru Fan to maintain a role that played a punching bag in the class, and he usually didn't think that Ru Fan and Song Xinying got along very closely, and he didn't see Ru Fan intervene when he scolded Song Xinying before, but the head teacher would immediately come forward and punish himself while defending Song Xinying. So what is Ru Fan coming forward for now, could it be for this fill-in-the-blank question?

I can't think about it so much, Qiang Tao can only leave this classroom, he knows that if he doesn't leave hard, but still listens to the questions here with a shy face, then after returning to the real school, where should his face be put when this matter is reported?

"Who is afraid of whom, in that case, then I won't listen to this clown girl quacking here, I'll go to the next classroom. Hey, remember, you drove me away, don't call me back, maybe I'll find an easier way. After Qiang Tao finished speaking, he slammed the door and left.

Song Xinying has long been accustomed to the title of "clown girl", this is a title that her classmates will only use when they humiliate themselves, and she will no longer feel humiliated by it. What she is more concerned about now is how to tell every question well, so as to please people like Ru Fan and make them her friends.

In the process of speaking this time, Song Xinying became the one who was the most distracted. The title "clown girl" always lingers in her mind, and sometimes Song Xinying will comfort herself with Ah Q's spiritual victory, maybe one day she will become a white swan.

But in this school, isn't it also at the mercy of others to become a white swan?

"I'm sorry, guys, but I'm ...... I'll go to the toilet first. Song Xinying stood up and bowed to the few classmates who were listening to the lecture and apologized, when she needed to get up and apologize, her legs were not weak, or maybe because she had no fear at this time.

This time, no one stopped or cared about asking Song Xinying, even Ru Fan only lowered his head and made the fill-in-the-blank question that he couldn't do before, and Song Xinying left the soundproofed classroom temporarily.

After Qiang Tao came out, he hurriedly ran to the next classroom, clinging to the back wall, his ears against the wall trying to catch the sound of Song Xinying talking about fill-in-the-blank questions. It's a pity that the walls are very thick, and he can only hear a subtle sound, and he can't hear what Song Xinying is talking about at all.

"Damn, how do you do this?" Qiang Tao held the paper in his hand, and his eyes kept looking at the fill-in-the-blank question on the paper as he stuck to the wall. Although the question can be understood, Qiang Tao has no idea to solve the problem at all.

The subtle sound coming from the inside of the wall suddenly stopped, Qiang Tao was a little at a loss, he thought that Song Xinying had finished speaking.

Suddenly, Qiang Tao heard a hair-raising sound, which was very loud and clear, as if someone was scratching the glass with his hand in his ear, and the sound was a bit like it came from the classroom where he was.

Qiang Tao stayed where he was for a while, and no one came out of the classroom next door, as for outsiders like Liu Xian'er, they should go to the dormitory building with the deputy squad leader at this time. So who is making this strange noise in this classroom right now?

He mustered up the courage to look back, only to find that Song Xinying had appeared in this classroom at some point. Song Xinying was facing the blackboard, holding a piece of chalk in her hand and writing on the blackboard about the fill-in-the-blank question, but the sound of chalk rubbing against the blackboard was too weird.

Qiang Tao naturally knew that Song Xinying had come to take the initiative to please herself, and the girl wanted to make herself forget the previous unpleasantness. But Qiang Tao will not treat Song Xinying well because of this, he even wants to tease Song Xinying again.

"Yo, why did the clown girl take the initiative to send it?"
