The worker who came to install the water purifier was busy in the kitchen, changing the pipes, and then the line, Zhu Yuexin beckoned and looked at it for a while, and quietly asked the worker who was talking to Wang Wuyun about the price of this thing installed at their home.

"We are acting as an agent for the best foreign brand, and Mr. Wang is asking for the installation of the most expensive machine in our brand, this machine is also doing activities and promotion now, one installation, free maintenance for life, so the price is also a little expensive......

"Ah, how much is that?"

The worker master said a price, which startled Zhu Yuexin.

Zhu Yuexin returned to the living room with a complicated feeling.

"Wuyun, it's too expensive!" Zhu Yuexin looked at Wang Wuyun and said, very embarrassed.

"In my opinion, it's not expensive, my uncle and aunt used to take care of me so much, what is this little thing, it's just to let you drink some clean water at home!" Wang Wuyun shook his head and said lightly, " If you want to take me as a friend, don't say this again in the future, by the way, in addition to this water purifier, when you are at home on Saturday in the future, I will also ask the vegetable and fruit distribution company of Nanjiang Agricultural Reclamation Group to deliver to your family what you want to eat next week, you pay attention to receive it, those vegetables, fruits, meat and eggs are of high standard, and they are exported to the European Union, uncle and aunt want to ask, you find a reason to deal with the past, it is really not okay, you will supply me again!"

"Okay, I won't talk about it!" Zhu Yuexin's heart was moved, he sucked his slightly sour nose, and changed the topic suddenly, "By the way, Wuyun, you just said that there is fluoride in this water, will there be any health harm if people eat fluoride?"

"No harm on the surface!"

"Oh, then why are you so nervous?"

"Do you know where the fluoride in your body ends up when you eat it?"

Zhu Yuexin thought for a while, "Metabolized?"

Wang Wuyun shook his head, "No, only a small part of the fluoride in the body will be metabolized, and the rest is still in the body, guess again!"

"Will it be absorbed by bones?"

"That's not right!"

Zhu Yuexin tilted his head and thought about it again, "If this thing is harmful, the human liver is detoxified, and this thing should precipitate on the liver!"

"The logic you said is fine, the liver is indeed detoxified, but this thing will not precipitate on the human liver!"

Zhu Yuexin scratched his head, "Where will it settle, I can't guess ......"

Wang Wuyun pointed at Zhu Yuexin's head, "They will eventually settle in a certain area inside your here!"

"Ah, you mean my brain!" Zhu Yuexin asked in surprise, "In the past, I shouldn't have eaten less fluoride-containing water, but I didn't feel anything wrong, it shouldn't be harmful to health!"

"That's all it takes to define your health!"

"What do you mean? Are there many kinds of human health?"

"People's health includes many levels of things, including physical health, as well as mental health, but in terms of physical health, it can be divided into many levels, what you call health is only the ordinary standard of health, but above the ordinary standard, the human body actually has a higher health standard!"

"What is a higher standard of health?"

"Have you seen X-Men?"

"I've seen it, what's wrong, does this have anything to do with what we said?"

Wang Wuyun didn't answer, but suddenly asked rhetorically, "Who do you think is the best in "X-Men"?"

"Magneto, of course!"

Wang Wuyun sighed, his gaze suddenly became deep, and after a few seconds, he said faintly, "If Magneto completely loses his superpowers one day, do you think his body is healthy?"

"That's a movie, besides, how could Magneto lose his superpowers?"

"If Magneto eats too much fluoride, it is estimated that he will no longer have superpowers, and he can only become an ordinary person......" Wang Wuyun spread his hands.

"Hahaha......" Zhu Yuexin was slightly stunned, and then laughed, thinking that Wang Wuyun was joking with him, "Your joke is interesting!" Just finished laughing, he suddenly remembered something, "By the way, by the way, I almost forgot, and one more thing, did you download WeChat on your mobile phone?"

Wang Wuyin knew that it would be difficult for ordinary people who were accustomed to the "inside the cage" cognitive model to accept the "outside the cage" cognitive model all at once, so he didn't continue, but replied according to Zhu Yuexin's words, "I have WeChat on my phone, but I haven't registered yet!"

"You hurry up and register one, let's add a friend, it will be convenient to contact in the future, I can also pull you to the WeChat group in the class, and now it is estimated that you are the only one in the class who has not joined the group!"

Wang Wuyin quickly registered and logged in to WeChat with his mobile phone number, and the name of WeChat was Wang Wuyin, and the avatar simply chose a four-leaf clover representing luck.

As soon as he got these things done, Zhu Yuexin added Wang Wuyin's friends, and then pulled Wang Wuyin into a group called "Qu'an No. 2 High School Class 1......

Inside the group-

Zhu Yuexin sent two messages in a row - everyone welcomes Wang Wuyun from our class to return to the team!

Below is a picture of applause.

It's just that soon, the class group that was still silent suddenly became lively.

Zhao Tianyang: Idol, I didn't see it before, please accept my worship!

Xu Zhengheng: Awesome, classmate Wang Wuyun made our sophomore class completely famous in school......

Liu Yumiao: My cousin is in her third year of junior high school, and two days ago she asked me if there was a person named Wang Wuyun in our class, who beat up the school's big pervert for the girl she had a crush on, which was very happy.

Gao Shan: Wang Wuyin, if you want to tutor English in the future, even if you come to me, I will make it up for you for free, by the way, do you want to take notes in the past two days?

Looking at the beating avatars, Wang Wuyun had a special feeling in his heart.

Just when the group was lively, all of a sudden, a discordant voice suddenly appeared.

Chen Zirui (Vice President of the Student Union of Qu'an No. 2 Middle School): Please pay attention to the discipline in the class group, distinguish between right and wrong, don't chase after the wind, Wang Wuyun beat Vice Principal Dai, it's not right, he has been punished by the school, he has a major demerit, and he is suspended for a semester, Wang Wuyin, I think you should find a separate opportunity to come to the school to apologize to Vice Principal Dai Qiang, and also apologize to all the students in our class, what you did has had a great negative impact on our school and class......

"I'm grass, Chen Zirui, this stupid X, I entered the student union with a drill, and when I became a vice president, I felt that I was amazing, would I speak human words......" Zhu Yuexin gritted his teeth and was about to send a message to scold him, but Wang Wuyun pressed his shoulder, didn't let Zhu Yuexin send anything, and sent a message under Chen Zirui.

Wang Wuyin: @陈子睿 (Vice President of the Student Union of Qu'an No. 2 Middle School), does your father know that you have recognized another father at school?

"Puff......" Zhu Yuexin couldn't help laughing when he saw Wang Wuyun's speech......

Chen Zirui on the other side of the screen also became popular all of a sudden, but he didn't expect Wang Wuyun, who had always been well-behaved in the class, to dare to talk to him like this.

Chen Zirui (Vice President of the Student Union of Qu'an No. 2 Middle School): Wang Wuyun, how the fuck do you talk?

Wang Wuyin: I'll just talk like this, the female classmates at school were bullied by Dai Qiang and didn't see you jump out, the female teacher was harassed by Dai Qiang and didn't see you jump out, Dai Qiang has something to do, you just fucking jumped out, are you still ready for me to apologize and take a screenshot of your WeChat to show yourself credit? It is because of the existence of people like you that the student union in the school that should serve the students has become a reptile concentration camp that kneels and licks the scum like Dai Qiang!

Chen Zirui on the other side didn't know if Wang Wuyun had told him about his plan all of a sudden, and he was silent all of a sudden.

Zhu Yuexin was laughing wildly on the side, his stomach was already hurting from laughter, he felt that what Wang Wuyun said was too sharp and too relieving.

Zhu Jia: This is our class group, not in school, and I don't think some people should use chicken feathers as arrows here......

Wang Tao: Zhu Jia is right, this is the group of students in our class, not the group of the student union, the only rule in the class group is that everyone speaks freely, if anyone feels uncomfortable here, please leave by yourself......

Zhu Yuexin: You are the best......

Tong Baichuan: Some people don't want to think about it, Wang Wuyun even dares to fight Dai Qiang, and he still cares about you, are you better than Dai Qiang?......

- Yao Ming's smiling face picture!

Zhang Yang: Is it only me who thinks that Wang Wuyun's summary of the student union is very good?

Wen Jing: Those people in the student union moved the officialdom outside the school to the school one by one, thinking that they were the leaders and cadres among their classmates, and they pretended to be commanding and commanding everything, making the student union miserable......

......

The group suddenly became lively.

Under the excitement of the crowd, Chen Zirui did not say anything anymore......

Maybe it's been lonely for too long, looking at the classmates in the group talking and speaking for themselves, Wang Wuyun felt a long-lost warmth in his heart, and he was a little moved.

just said a few words in the group, and soon, Wang Wuyun's WeChat address book had a large number of classmates who wanted to add his friends......
