The first rays of sunshine in the morning sprinkled on the windowsill, today is a little different, the first mock exam in the third year of high school, Song Ran didn't have to go to school to study in the morning, but in order to send Cheng Wangshu to school, he still insisted on going to school with Cheng Wangshu. He always said that the days when we could go to school together like this were numbered, and we had to make good use of the day.

"Today is the first model exam of the third year of high school, do you know what it means, it means that you have one foot in the preparation line for the decisive college entrance examination, so you all seize the time, and now everything can be leaned back. Those who fall in love, I don't care if you fall in love, but don't delay my studies, and see how I clean you up when my grades come down. After Sun Ning said this, he walked out of the classroom with its black folder.

The moment he walked out of the classroom, there was an uproar in the classroom, and before Cheng Wangshu could react to what was going on, there was no sound for a moment, it turned out to be Sun Ning standing at the door of the classroom with a calm face. He said in his characteristic voice, "The hallway is full of the voices of our class. ”

In the days that followed, whenever Cheng Wangshu saw movies and TV series about high school, when he saw this sentence, he always remembered this English teacher who liked to wear oversized logo half-sleeves and oversized logo sneakers.

"Cheng Wangshu, do you watch anime?"

"Look,But I don't watch Chinese comics.,I prefer Japanese comics.,Comics.,I watch all anime.。

"Have you watched Tokyo Ghoul, then?"

"Look at it, I really like Kirishima superly...... I like" Cheng Wangshu Balabala said, only to find that Sun Watermelon was looking at her helplessly, and when she was wondering, she heard a faint voice behind her: "Why do you like to sit here so much, go home and watch anime, you come out with me." ”

Fortunately, it was just to talk about anime, so Sun Ning didn't criticize her too much, just reprimanded her and let her go back.

When he went out from school, he was still surprised to see him standing at the door of the class, leaning against the window and looking at him with a smile on his face.

"Why didn't you go home and stand here, how long have you been waiting for me!"

"It didn't take long for me to see you being called out by the head teacher."

"Can't you just come a little earlier and remind me that the teacher is here?"

"I reminded you, but you were chatting with your chubby tablemate, and you didn't even see me!"

"So it's time for your self-study class to arrive, and you've been waiting for a class here, which doesn't make sense, shouldn't you go home and study hard? How about today's test, you must have done well, right? ”

"Why do you think I did well?"

"If you don't do well in the exam, you should have gone home to study a long time ago, how can you have time to come to me and tease my boring son."

Song Ran suddenly twisted Cheng Wangshu's shoulder as if she was angry, and let her look directly into her eyes: "Can't I come to you on purpose?" Can't I just come to you just to share my feelings with you? I ......"

Cheng Wangshu was stunned by his sudden question, the whole person was hard and pestle was there, and he didn't know what to say.

Probably seeing Cheng Wangshu's frightened expression, he didn't ask any more, just sighed softly, then let go of Cheng Wangshu, and helped her smooth the school uniform jacket that was scratched by him, and then walked away quickly.

"Song Ran, did you not do well in the exam? Is this what it looks like? And the results haven't come out yet, so you don't have to be under so much pressure. ”

"It's really hard to hear you comfort me." He looked at Cheng Wangshu with a disgusted expression, and then sat down along the basketball hoop in the playground. He rarely sat down before himself, and it was usually he who sat here comforting himself.

"Aren't you the omnipotent and omniscient Song Xueba? Do you still need comfort? ”

"Cheng Wangshu, are you all pasty in your head? I'm a high school student too! I'm going to be stressed, too! ”

"Oh, it turns out that Xueba is also a human being!"

"What the hell is going on in your head every day?" Song Ran looked at Cheng Wangshu, he didn't understand what the girl in front of him was thinking about every day.

"Have you ever heard of a lighthouse jellyfish?"

"What's that? Let's hear it. ”

It is a kind of jellyfish that can live forever, they may be born with jellyfish buds or eggs, and then slowly grow into juvenile, youth, middle age, and finally old age. But the 'lighthouse jellyfish' are different, they will go back to the jellyfish bud stage, then regrow, then slowly grow old, and then go back to old age, and the infinite cycle will lead to eternal life. ”

"It's not in line with the laws of biological development, so I don't think it's reasonable." Cheng Wangshu looked at Song Ran and explained this question seriously, and felt that he was very interesting.

"Some people say that when the lighthouse jellyfish reaches old age, they replace all the dead cells with new ones, so is this jellyfish still the same as the original?" So Cheng Wangshu continued to ask his own questions.

"The question is the problem of the 'Ship of Theseus', when the last part of the ship is replaced, is it still the same ship? If you ask me, I don't think it's so. ”

"Don't understand?" Cheng Wangshu shook his head, Song Ran looked at her with a curious look and felt very interesting, so he still explained to Cheng Wangshu.

"From a biological point of view, all the old cells in the human body are metabolized every 7 years, but you don't regenerate every 7 years, do you?

A living individual is a fertilized egg cell that undergoes cell division and cell differentiation to form tissues and organs, and finally grows into a human. Each cell in an individual's body carries the same parental gene, which is passed on to them as it grows and multiplies, so that all new cells remain the template for the original parent cell. That is, even if the cells of the individual are all renewed, the genetic traits have not changed, and you are still you. In particular, stable brain nerve cells keep you awake for the rest of your life. ”

"So: the only thing that can confirm that I am mine is my consciousness?"

"Hmm...... What weird stuff do you have in your head? Song Ran listened to Cheng Wangshuqi's strange theory, and didn't know how to explain it to this girl, so he could only pat her head helplessly.

"That's what you said! What are you hitting me for? ”

Song Ran looked at her holding her head, and felt that this girl's strange thinking was sometimes very interesting.

"Your problem does not exist, because the life cycle of various cells in the human body is different, and it is impossible to have a consistent update completion time. As a result, no matter what time of day, there are always new cells and senescent and dead cells.

There are hundreds of billions of cells in an adult's body every day, and hundreds of billions of cells are also dying at the same time, and the two are in a dynamic equilibrium. Cell regeneration is the need for human growth and repair. In the dead cells, in addition to necrotizing death, the autonomous and orderly apoptosis of cells under gene regulation is to prevent excessive proliferation and stabilize the internal environment. The two are opposites and unified biological phenomena, the inevitable laws of life processes. ”

"I don't understand."

"It's weird that you can understand, it's really in a bad mood, but it feels much better for you to mix it up like this. Let's go, send you home. ”

"But I haven't figured out what's going on, so don't me!"

"Wangshu, have you ever thought that after I go to college, we will only see each other once in 4 months, what should we do? I can't stay with you then. Song Ran stared at Cheng Wangshu's eyes, hoping to see a trace of nervousness or other emotions in her eyes.

"It's okay, I'm not a kid anymore, I can take care of myself." Cheng Wangshu's indifferent tone made Song Ran's heart feel a little painful.

"What if I had another girl I liked in college?" Song Ran's tone was a little aggrieved.

"Well, it's normal, girls in college must be much more interesting than high school, and like the college you're going to, there must be a lot of excellent girls, so it's not surprising that you like other girls, people will always be attracted to people who are better than themselves."

Cheng Wangshu raised her head and her big eyes flashed with sincerity, and she looked at Song Ran and said word by word.

"You!" Song Ran gritted his teeth and looked at Cheng Wangshu, and then squeezed out such a word from between his teeth.

"Don't worry, I'm definitely not that kind of girl with a big nose, if you have a new girl you like in college, you can just tell me, I will definitely abdicate and make way for Xian, and I will definitely not be entangled." A trace of sadness flashed in Cheng Wangshu's eyes, Song Ran was probably angry by Cheng Wangshu's words, so she didn't notice her emotions.

"I don't want you to abdicate and make way for Xian, I want you to be entangled!" Song Ran's voice suddenly raised a lot, and his face flushed with anger, but Cheng Wangshu didn't dare to look up at him.

"But I don't want it, that's too ungraceful, I'm not unwanted, feelings are originally what you want me to do, you like me, we're together, you don't like me anymore, we'll get together and disperse, and the twisted melon is not sweet!"

Cheng Wangshu lowered her head with some tears in her eyes, but she still endured it alive, and when she raised her head again, her eyes were clear when she looked at Song Ran.

"Cheng Wangshu!"

"What are you yelling at me for! Scared my mind! Look at the way your eyebrows are raised, it's so interesting, hahaha! Her laughter pierced through the walls, but it couldn't hide the choked cry of her laughter.

"You're so ruthless!" Song Ran turned around and strode forward, only listening to her hearty laughter.

"Heartless? Maybe, I've never been a person who likes to be reluctant to give up, and the more entanglement you have, the more you hate me, and if that's the case, I'd rather leave you with the best smile. Cheng Wangshu's heart swelled with some sour feelings.

Probably because the breath of the college entrance examination is approaching, even Cheng Wangshu began to become nervous, and the spring wind gradually became warmer, but the smile on Song Ran's face gradually became less, Cheng Wangshu always wanted to ask what happened, but every time he wanted to speak, Song Ran used some other topic to divert him, and Cheng Wangshu didn't mention it with interest.

"By the way, I'm going to prepare for the provincial joint entrance examination and the art exam, and I'm going to get up early every day to run and practice morning exercises, do you want to come with me?"

"I'll forget it, I study until the second half of the night every day, how can I have any motivation to get up early and run, you better go by yourself."

"Alright then, my lonely morning exercise!"

In the next few days, Cheng Wangshu got up at 4 o'clock in the morning every morning to practice morning exercises, Song Ran still came downstairs every day to pick him up and go to school together, and there was not much time to stay together, Cheng Wangshu could feel that he was under a lot of pressure, but he couldn't ask about his grades.

"Wangshu, give me some encouragement, I feel a little tired." Song Ran's expression looked tired.

"What's wrong?"

"It's not much, it's just that I quarrel with my dad at home every day, and I'm tired of arguing." Song Ran's tone was a little self-deprecating.

"Song Xueba, will there be a time to go home and be scolded?"

"Miss Cheng, even if you are a scholar, you will be tired, okay, I am not a god." Song Ran was amused by Cheng Wangshu's words, and he found that in the eyes of this girl, he seemed to be an omnipotent person, no trouble, no scolding, and no anger.

"Oh, come on, I'm sure you can!"

"That's it?" Song Ran looked at the smiling Cheng Wangshu and felt in a trance, her body exuded the unique fragrance of a girl, and the pink between her lips only wanted to taste the taste of her lips.

"Or else?"

Song Ran couldn't suppress the impulse in her heart when she looked at her playful appearance, and her body suddenly approached Cheng Wangshu, and then stopped just when she was about to kiss her.

Cheng Wangshu didn't dodge this time, not so much because she didn't dodge, but actually looked at him without emotion, and there was a little more disgust in his eyes.

"Wangshu, I'm just ......" Looking at her appearance, Song Ran's heart suddenly panicked, he wanted to explain something, but she refused, she took a half step back coldly, allowing herself to distance herself from her, and then showed his familiar smile.

"You don't have to explain, I just don't like it, it's okay." After speaking, Cheng Wangshu turned around and strode away, and the smile on her face faded the moment she turned around.
