As soon as the content was published, someone grabbed the sofa under Weibo. Of course, there are also good students who carefully analyze the questions. Cheng Jibei was eating breakfast while scrolling through netizens' comments. "'s comments were pushed to the top.

@应实局居: l=2πr.It has nothing to do with the type of ball, and it has nothing to do with 1.same size.Be good, cultivate more geographical awareness and less math problems.

Refresh again, and there are dozens of replies under the comments of the Department of Yingzheng in an instant.

@胡罗胡狗拓儿: 66666 Don’t say I copied it, I haven’t even finished reading the topic yet [Goodbye]

@白天_高三 is determined to blog less: Am I the only one who thinks the following sentence "good" is spoiled by honey?Our candy is coming soon, the main father is sending out candy (#▽#)

Cheng Jibei felt the parsley he had just eaten choked in his throat.

——Speaking carefully, do high school students now have such big brains?

More than a year ago, Cheng Jibei, a young player majoring in geography who was in his senior year, was determined to serve his motherland while taking the postgraduate entrance examination.

As one of the largest comprehensive live broadcast platforms in the country, in addition to common live broadcast items such as game competitions, singing and dancing, Mose Live has also specially designated a teaching area to keep pace with the times, and signed some teachers like Cheng Jibei. The teacher who is sincere in his dream of education () is stationed in the station to offer live webcast courses.In order to attract more students, the teaching area of ​​Mose Live has also developed a special function: the anchors will randomly select a few students to do the questions in the barrage, and the students' problem-solving steps will be displayed on the storyboard in the lower right corner of the live broadcast room .Since most of the problem-solving steps are displayed in white characters on a black background, everyone calls it "doing problems on the blackboard". It feels like returning to the three-dimensional classroom.

Cheng Jibei's live broadcast class is from 08:30 to 10:30 every Tuesday, Thursday, and Saturday night. In addition to the normal lectures and knowledge point analysis, he often teaches some test-taking tips in the live broadcast. Some students came to the blackboard to interact with the questions based on these skills.

It is a happy and painful thing for the students to be able to do questions on the blackboard in Cheng Jibei’s live broadcast room. The joy lies in hearing Mr. Jibei’s gentle voice like a male anchor at midnight calling his ID. The pain is that the questions he gives are basically free propositions. Occasionally, he can guess a few of the objective questions correctly by intuition, and few people can get all the scores for the subjective questions.

Teacher Cheng Jibei, whose teaching philosophy is "non-toxic and not husband", has always been strict with others and lenient with himself. Students who have been on the blackboard are basically sprayed by him. Even so, a large number of students will still come to do it the next day. When it was time to answer the question, he excitedly swiped "Teacher sprayed me" in the barrage.

When I thought of the teacher frowning and looking at the questions I didn't get right, he said to me gently: "I'm afraid your Turpan Basin can hatch polar bears, so hurry up and grow some snacks." I am so excited! ——Excerpted from the Weibo profile of Ms. Zhang Junya, a loyal audience of "Teacher Jibei's Geography Classroom".

Cheng Jibei, who originally had the mentality of passing through the boring period of senior year, got a group of shaking M students and a considerable income by accident. Therefore, he still did not give up this part-time job after he was directly promoted to our school and became an honorable graduate student. A lot of teaching aids have been purchased for good classes.Over the past year, Cheng Jibei's live broadcast room "Ms. Jibei's Geography Classroom" has accumulated a lot of popularity. Not only have regular students attend classes on time every night, but in recent months, there have also been a few caring little housekeepers to help Maintain barrage order.

However, more than a month ago, there was a sudden ripple in the calm water in Cheng Jibei's live broadcast room - a mysterious boss with the ID of Ying Que Siting was born out of nowhere.

It was Thursday that Ying Quasi Hall suddenly appeared.

On that unusual Thursday afternoon, Cheng Jibei was temporarily dragged by a group of senior fellows from the Second Research Institute to be a data recorder for the soil analysis experiment. With a rigorous and truth-seeking attitude, the seniors tirelessly groped and failed in the pursuit of truth. ...

Time passed by every minute and every second, seeing that the time for the live broadcast was approaching, and the brothers had no intention of ending the experiment at all, Cheng Jibei burst out with amazing acting skills in desperation, and shouted "Brothers hold on to me to release myself It's gone!!" Throwing down the notebook and rushing out of the laboratory, he sprinted back to the dormitory at a speed of [-] meters.

The earth-shattering battle when Cheng Jibei opened the door made the roommate Xie Zhili, who was crouching at the foot of the bed and looking at Li Fan, drop his mouse in fright.

"Cheng Youqian, have you been hunted down?" Xie Zhili patted his chest and rolled down from the bed to pick up the mouse, watching Cheng Jibei quickly turn on and debug the live broadcast equipment with a confused face.

Cheng Jibei had no time to be Xie Zhili's supporter, and focused on adjusting the angle of the camera: "Tonight's live broadcast will be broadcast, and you will be charged [-] if you are late."

Xie Zhili suddenly realized. After picking up the mouse, he turned over and rolled back to the upper bunk to plug in his earphones: "Can't you get a photo of me? I won't be on camera if I don't shave today."

Usually, even if you wear a suit and tie, you don't dare to be photographed, okay?Cheng Jibei silently rolled his eyes.

After dragging out the whiteboard and a few maps for class, and adjusting the angle of the live broadcast, Cheng Jibei pressed the red dot of "Start Live Streaming" and watched the number of online viewers of the live broadcast slowly increase.

"Hello students, welcome to today's geography class, I'm Jibei." Cheng Jibei greeted the barrage crowd very skillfully.

"Good evening, Beibei! Today is also a big brother who is full of gentleness and strength!"

"Beibei skipped my evening self-study just to see you, praise me!"

"The one in front who said she was gentle and powerful might be the Mushroom girl who forgot the last class and cried at the blackboard hahhh"

"Gentleness? Nonexistent"

"My northern real straight man can't even coax a girl. I really feel sorry for his future girlfriend."

Seeing that the direction of the barrage was unconsciously going in a strange direction, Cheng Jibei quickly spoke to turn the tide: "Today we will review the knowledge points about the sun's altitude angle."

"The sun's altitude angle refers to the angle between the incident direction of the sun's rays and the ground plane. Simply put, it is the altitude angle. When the sun's radiation is at its maximum, do you think..." Cheng Jibei drew on the whiteboard while explaining Simplified picture, the topic about Cheng Jibei’s future girlfriend in the bullet screen is gradually replaced by the students’ course questions. Cheng Jibei occasionally picks out a few frequently asked questions in the bullet screen to answer them, and subtly reveals the topic about the sun. Several types of questions about altitude angles were introduced to the students.

"There is also the No. 11 question of the Zhejiang Wenzong paper last year. This is a multiple-choice question that requires us to calculate the angle of the sun's altitude. Normally, you stupid people will think about it and don't want to directly substitute it into the formula when you get the paper, right?" Cheng Ji The North Killer didn't blink, and directly took the lead to attack the little fans, "Then if you make mistakes after tonight, don't say you watched my live broadcast, okay? I'll brush up the Weibo topic for you# Geographic exam owes me a computer#."

The bullet screen was filled with "23333" and "the teacher scolded me"... Shaking M so much that Xie Zhili, who accidentally caught a glimpse of the screen, suspected that the live broadcast room opened by his roommate had a mind-destroying function. Of course, the roommate's own score should also be to a certain extent The Internet caused the destruction of the minds of netizens in the live broadcast room...

Cheng Jibei copied the content of the topic on the whiteboard, turned around and found that the barrage in the live broadcast room had changed.

——The quick "see boss" "666666" and "thank you for the crown" made him suspect that he had traveled to the live broadcast room of the little sister who was wearing a low-cut leopard print and sang "Social Shake" in the next door.

Cheng Jibei subconsciously leaned closer to the screen to confirm the information in the live broadcast room.I don't worry if it's still Teacher Jibei's geography classroom... what a ghost!He was horrified to find that No. 1 in the gift area of ​​the fan group had become a level 1 trumpet with the ID "Ying Que Si Ting". "Send to the North's little teaching assistant", at the moment it has dropped to the second place aggrievedly, which is in stark contrast to the Yingji Hall, which is still rising in gift value.

As a profit-oriented live broadcasting platform, Mose Live Broadcasting is naturally indispensable to rewarding the anchors with various gifts. Roses are the most common rewarding gifts, which cost 5 yuan each. Scepter, crystal ball and other gifts, the most expensive crown is 888 yuan each. It is said that a well-known e-sports player in the game area can receive three-digit crowns for one live broadcast.

At this moment, Cheng Jibei saw that Ying Que's reward record in this room had stopped at "100 crowns".

100 888 × = 88800

Eighty-eight thousand eight hundred yuan.

Mom, I seem to see what is called the future.

Cheng Jibei calmed down his excitement, stabilized his trembling voice and said: "Thank you for the hundred crowns from the classmate whose ID is 'Ying Que Si Ting', welcome to my live broadcast room." Damn it is so happy OK!

However, Cheng Jibei knew in his heart that most of the people who watched the live broadcast in the teaching area were some students, and even the rich second generation rarely had such a large amount of money.As a five-good young man (who thinks he is) the successor of socialism, Cheng Jibei ruthlessly added: "If you make a mistake because of trembling hands, you can contact customer service to apply for a refund."

The barrage seemed to stand still for a moment.

After a few seconds, the bullet screen was filled with "I Bei is really a kind person with a gentle heart" and "A teacher with very upright views. I love my Bei forever".

Then, Ying Que Siting posted his first barrage after entering the live broadcast room.

Ying Que Siting: No shaking hands, your class is very interesting, I will come to listen to it often in the future.

Cheng Jibei felt a small firework explode in his heart—he automatically translated Ying Que Siting's words, which to him were simply the most beautiful love words in the world.

——Your class is very interesting, I will often come to reward the crown in the future.

Ah, it's nice to have money.

The author has something to say:

Hi big Karma!Surprised or not, unexpected!

Sudden attack post=333=

This time the inspiration came from visiting station B one day and suddenly saw a live broadcast room where a teacher was teaching physics. I was shocked why there are still people squatting live to learn knowledge, and then opened a brain hole to talk about small anchors and local tyrants If nothing else happens, it will be updated every day. Here, I would like to thank my little friend who has been following me for such a long time, eh!
