"Wait for the lights, wait for the lights......" The bell rang on time.

Teacher Xu helped the black-framed glasses on the bridge of his nose and closed the teaching tablet, "Go out and run slower after school, now class is over!"

When the words fell, the classroom suddenly became noisy, some people packed up their things and ran out of the door, some people were busy talking and laughing, some people grabbed snacks and stuffed their mouths, and some people walked up to the podium with textbooks.

After changing the two ways of explanation, the students finally thanked and left. Xu Man nodded with satisfaction, turned his head to look at the others, but no one came up to answer questions, so he had to stuff his tablet into his briefcase and go back to the office in a huff.

Actually, this is normal. The difficulty of ninth-grade chemistry is limited, and the course has only been two months since it began, and every day is to burn and burn to see, and there is still a period of time before the trim equation and the periodic table are memorized, and most students have not yet realized the horror of the chemistry demon.

The Bee School had a public office for the trainees, but she moved her desk to Zhang Xuyao's room.

Pushing the door in, she saw several boxes of express packaging bags thrown on the ground, and her daughter was holding a utility knife in her hand and cutting the cardboard box on the table.

When she saw the colorful mobile phone pattern on the lid of the box, she was angry: "You have so many mobile phones, why do you spend money indiscriminately?"

was reprimanded by his own mother, Zhang Xuyao said that there was no pressure. Dropped the knife, took the briefcase and put it on the table, pressed my mother to the chair and sat down, took a full glass of water and handed it to the other party, she smiled and asked, "Mom, why are you so angry?"

Teacher Xu was so angry that her hand shook but a lot of water spilled out, and when she put the paper cup aside, her anger was much smaller, and she glared at her and asked, "Do you want to say that you can earn money by your ability, and you are willing to spend it as much as you want?"

"No, no, no," Mr. Zhang shook his finger, "This phone was given to me by the manufacturer, as long as I help shoot an advertisement." Anyway, it was a benefit delivered to the door, so I reluctantly accepted it. ”

"You!" Xu Xu pointed to his daughter, hating iron and steel: "Can't you go to your class well?

"Mom, the mobile phone is not a food, medicine and dairy product, it is very safe. ”

"What if it's not up to par quality and the explosion hurts someone?

"Hey, will the phone blow up?" Zhang Xuyao looked at his mother, "It's understandable that others don't know how to talk nonsense, mom, you're a chemist!"

Whether it is a column lithium-ion battery for power banks or plate polymer batteries for mobile phones, there are special safety valves and safety wire designs, which can automatically decompress even if there is a failure, and will not really explode, but may catch fire and burn.

was taught a lesson by his daughter, but he didn't get angry, but stroked his palms with both hands and said excitedly: "Very good, that's all!"

"Hmm, what's good?" this time it was Zhang Xuyao's turn to be confused.

"Good daughter," Teacher Xu looked at her and said, "It's time for you to contribute to the cause of education!"

"What's with what? Why did you get to me again?"

"Hehe," Mr. Xu rubbed his hands, "next week's interesting chemistry experiment, I plan to find a few mobile phones to burn, you have so many old mobile phones, bring me a few to burn!"

"No problem!" Zhang Xu Yao agreed, this request was not difficult at all. The frequency of her phone replacement is already very high, and after receiving a bunch of mobile phone advertisements this year, the eliminated mobile phones are even more piles of them. The good-looking ones were taken away by her, and the rest were all kinds of old machines that couldn't run, and they were burned and reused.

"However," she said hesitantly, "these mobile phones should not be easy to ignite, and my brother Jing has very high requirements for battery safety." ”

"It's better or not, just look at it," Xu Xu said with a look of fascination, "You can try the remote control glove box here." ”

When conducting physicochemical and biological experiments such as toxic, irritating, radioactive, and infectious, experimenters need to use a glove box to protect themselves. The box is completely sealed and has an independent air circulation system, and the experimenter operates the experiment through a pair of long gloves on the side wall, so it is called a glove box.

The equipment of the Bee School goes one step further, the box is equipped with a camera and a remote control robotic arm, and people can watch the reaction in the box through VR glasses outside, and then control the manipulator through somatosensory gestures to conduct experiments, which further improves safety, and can also replay the contact at any time to save drug consumption. The whole system is somewhat like a da Vinci surgical robot, but with much lower accuracy and cost, which is a new use for Bee's own VR products.

Mr. Xu had only watched the relevant videos before, but he had not actually used them, after all, this kind of large-scale equipment had to be reported and applied, ********and simple experiments such as oxygen production and dilute sulfuric acid hydrogen production were not eligible to use it.

Seeing her daughter looking at herself with "you can really toss" eyes, Xu's mother was a little embarrassed, and knocked on the mobile phone box to change the topic: "Why is this mobile phone so thick, it looks weird?"

The smartphone industry is popular for "convergence evolution", and the appearance looks similar, even to the point where you don't know the brand model without looking at the trademark. But that's not the case with this phone, which is angular and thick, and looks unusually eye-catching in line with the trend.

"It's!" Zhang Xuyao picked up the box, "This is a black mobile phone, and it is normal for it to have a strange appearance." ”

"Huh?" Hearing this, Xu Zhi's suspicious eyes immediately shot in, "Are you lying to the ghost?" 'Black Pearl Smart Camera Phone'! Why is the name in Chinese, and African blacks can understand it?"

"Well, this is the manufacturer's plan to export to domestic sales, specially made a batch of Chinese packaging of the national version of the test water. If it weren't for this, they wouldn't have found me, after all, your daughter is not very popular in Africa. ”

Explaining, Zhang Xuyao pulled the box over, took the utility knife and opened the seal. The lid was removed to reveal a black phone in a soft plastic bag, surrounded by basic accessories such as data cables and headphones.

"The domestic market has peaked, and all manufacturers are busy going overseas to find growth, with high spirits going to the United States and Europe, low requirements going to Latin America, and many going to Southeast Asia and India. Brother Jing and they took their partners to Africa, and this black pearl is a successful case of cooperation between the two sides. ”

Tearing open the bag and taking out the mobile phone, Zhang Xuyao showed the back panel of the mobile phone to her mother, "See, the woofer specially customized for the African people can play the drum and sing anytime and anywhere." ”

"I said how it looks so thick, it turns out that there are two more speakers," Xu Xu pouted, "I remember that there were such knockoffs ten years ago, and I have seen eight speakers." ”

"That's different,The kind of cottage machine only emphasizes more speakers、The sound is loud,It's all noise pollution,This amplifier unit is at the speaker level,The sound quality is much better,You don't need to bring Bluetooth speakers when you go out in the future。 ”

"Oh, by the way, that's not the maximum thickness of it!Wait for me to turn it on first," Zhang Xuyao lowered his head and pressed the power button, a black pearl scrolled around on the blue background, and then entered the main desktop, the wallpaper and icon style are the default settings of the bee 7 system.

Even if it is open to third parties, Bee has a firm grip on the control of the operating system, the pre-installed system must be selected from several official versions, and the upgrades and app stores are also controlled by Bee. Of course, with a slap in the face, they also left some corner soup for the partner manufacturer, allowing changes to the splash screen, and a small amount of necessary software can be pre-installed.

When Zhang Xuyao skillfully rejected the "first-time use guide", he saw four pre-installed software icons appear on the desktop, one of which was "Recommended Black Pearl Theme", which was the entrance to the customized interface of the mobile phone. Happily clicked, the wallpaper turned into a dynamic water surface, and the original "new skeuomorphic style" application icons also turned into round and shiny colored pearls, which looked pearlescent and moist and quite fresh.

When the "speaker mode" is activated, the back cover of the phone clicks, and with a slight pull, it is pulled open a few centimeters like an accordion, becoming more like a speaker.

"What's the use of this, can you gather voices or what?" Teacher Xu asked curiously.

"Mom, you're so lonely! Speakers have the best volume,This can enhance the bass effect with a pull,It doesn't sound too harsh," said on his lips, Zhang Xu Yao started the FM radio module to play a song as proof, and the results came out of the speaker were all advertisements for height, beauty, and discounts. Fortunately, it's not midnight, otherwise it would only be more embarrassing to hear late-night phone calls and gender topics.

Turning off the radio stupidly, Teacher Zhang snorted: "No wonder there are fewer and fewer people listening to the radio now, all of them are advertisements, how can you listen to them?"

Closing the back cover and opening another app, she walked up to her mother, "Mom, let's take a group photo!"

Although the latter looked puzzled, he still skillfully compared the selfie style, leaving a group of intimate, warm, funny and cute ten consecutive shots.

"Hmm, what's going on?" Looking at the black mother and daughter with their hands on the screen, Mr. Xu's face was full of question marks: thick lips, wide nose, dark skin, instant noodle rolls, who is this?

"This is the two of us! If you don't know me, why don't you even know yourself? They all said that this mobile phone is designed for African people, and its beautification function is naturally black aesthetic oriented, and then it becomes like this!"

The front camera used by this phone takes a selfie by default, and no matter what race it is, it will be turned into an African black pearl by the beautification algorithm of the Bee Heart 437.

"I see," Permission nodded, "so you've turned black." Come on, send it to me. ”

Although she thought it was weird, she still threw these photos into the circle of friends with a curious and playful mentality.

Stuffing the mobile phone to the other party, Zhang Xu Yao said: "Mom, you take it first, don't be in a hurry to play, do me a favor first!"

When the two of them walked out of the office, they looked up and saw the long shadows of trees sprinkled on the ground painted with sunset yellow, and the whole campus seemed quiet and peaceful. At this point, the students of the primary and junior high schools have left, and the senior high school is either taking the fourth period of activity class or doing mock problems, and it is naturally quiet outside.

Walking to the place selected in advance, Zhang Xuyao skillfully set up a tripod, put his BP7 on it, and then walked to the side and stood facing west. Xu reluctantly launched a photo app, turned on the player and speaker, and put it in front of his daughter.

"Knock knock knock!" The sound of the deep drum came from the horn on the back cover, with the original local chanting, quite a bit of the vastness of the African land.

It's just that the female voice that sounded next immediately made people stunned, and they heard their daughter chanting repeatedly in the same tone as chanting: "Xuan Kefei! Krypton changes his life! Pray to draw a big red card! Xuan Gaifei ......"

It is the popular "Prayer Song for Leaving Africa and Entering Europe".

Europe is Europe, the hometown of white people, and a community of people with white faces who are lucky enough to produce the best; but not Africa, but in just four words, it carries the good expectations of generations of liver ship admirals, sleep-up demon masters, and the sons of Wang Yi, as well as resentment that is so strong that it is almost substantial.

Whether it's the island country DMM, or the bee game, or the three-stone net pig, online game companies are very stingy with card players, and everyone has a big red card and a high star card, which is the treatment only for private servers and stand-alone modifier players. Therefore, Europeans are destined to be only a minority, and the European royal family is even more of a minority, and most players can only be black, and it is more reliable to count on leaving Africa and entering Asia. The skin color of yellow people in Asia is between black and white, so the "well-off players" have regarded themselves as Asians.

Too many people sing this song when they burn incense and pray before drawing cards, sing this song when they fail to draw cards and destroy the whiteboard, and hum this song when they are bored waiting for the bus and waiting for a meal, so that this brainwashing saliva song has successfully become the most popular Internet divine comedy during this time.

When the pearl company found Zhang Xu Yao, it was to forcibly rub a wave of heat, after all, they are more professional when they get out of Africa and enter Europe!

The Black Pearl phone can shoot anyone as a black person, and it can also shoot a black person as a high-nosed, deep-eyed blonde and blue-eyed white person, as long as you change a few settings, isn't it just out of Europe?

Mr. Xu doesn't play domestic web games and mobile games, and he doesn't know anything about ten consecutive draws, star promotion, card strengthening, fate connection, and CV (dubbing) stars, so he naturally can't understand the lyrics full of the spirit of complaining and self-complaining, but this does not affect her to follow the dynamic rhythm and start shaking her legs and shaking her hands.

"The song is okay, but the lyrics are boring, and some of them are moaning without illness," she commented.

"Who said that, this is our life, the life of tens of millions of people!" Zhang Xuyao disagreed with her mother's statement, and made a gesture, "Okay, okay, Mom, don't worry about that, hurry up and try to shoot a section." I won't be able to shoot it when the sun goes down!"

Teacher Xu nodded, skillfully adjusted the preset plan, and motioned for her daughter to get ready to start.

The accompaniment of the music remembered again, and Zhang Xuyao, who had been prepared, immediately moved, and danced the exclusive dance steps of the prayer dance in the twilight of the sunset.

The action looks very strange, but after watching too much, it is also quite emotional, Xu's mother trembled and jumped in, jumping with her daughter, this is a little difficult, but it is difficult for her old man.
