Bell bell bell ~~~

When the bell rang for the end of school, Jiang Bing, as usual, put up a blushing face, and after looking left and right, he got up and prepared to go home.

"Jiang Bing, wait and go" Just as Jiang Bing passed by the door of the classroom, a voice came from a seat in the corner, and the voice subconsciously turned around, "Teacher Liu Xin?"

The last class was not Teacher Liu Xin's class, this was what Jiang Bing knew, but why Teacher Liu Xin was sitting in his seat, he was puzzled.

"Do you remember our agreement" Teacher Liu Xin called Jiang Bing to him and asked.

She wears a ring on her hand and is still spinning her pen as she speaks.

"Of course, how could I forget" Jiang Bing suddenly thought of his tutoring, and he had a hunch that something unexpected would happen next.

"Then, this is your teacher Hua Ye's phone number, I will put it in front of you now, I will ask something in a while, if you don't answer, how about I call" Liu Xin said.

"Yes, yes, but there is a lot of knowledge, I only understand the general knowledge, and I am not familiar with it," Jiang Bing said hesitantly.

"It's okay, just answer it, just let me know in your own words that you understand what it means."

“OK”。

"Sun Lu, you come in" Liu Xin shouted towards the door, and at this time, the sunlit shadow at the door that Jiang Bing had been paying attention to moved, and Sun Lu walked in.

The shadow was hers, she had been standing there before, because there were no classmates in the class, and Jiang Bing didn't know how long she had been outside.

"I asked you to help Jiang Bing before, did you do it?" asked Liu Xin.

"Well, let's do it..."Sun Lu forgot about this matter because of her previous lovelornness, and later played a game to completely forget about it, and now she was mentioned by Liu Xin, she was a little nervous.

"What is called, what is done is done, no is nothing".

"Yes" Sun Lu heard Jiang Bing's speech at the door just now, although she didn't know why Jiang Bing said this, but she had become friends recently, and she was still very confident in Jiang Bing.

In fact, Sun Lu's confidence in Jiang Bing comes from Liu Xin's sentence You can answer in your own words, according to Jiang Bing's consistent style, you can definitely get away with it, she firmly believes that of course this is her only way out at present.

Who asked her not to object when Liu Xin asked her before, and directly agreed, at that time, Jiang Bing could occasionally get up to listen to the class, Sun Lu felt that she was sure, but after so long, she had long forgotten.

"Then let me ask a simpler one, what is a nebula, and you explain the concept of nebula."

"Nebula...," Jiang Bing recalled.

"Ah" Sun Lu whispered, but Liu Xin didn't hear it, this is the content of the third year of high school, and the chapter is relatively late.

And during this period of time, Jiang Bing was absent from school except for sleeping, how could he know about Xingyun, Sun Lu secretly scolded bad luck, and the first question he asked was so tricky.

"Nebula is... Jiang Bing thought, he had just seen this place in the morning, and he thought it was very interesting at that time, and he deliberately took a few more looks.

"What's it, can't you answer" Liu Xin asked, Jiang Bing just dragged on for a long time, and refused to answer, making Liu Xin anxious and Sun Lu worried.

"Nebula is the general term for non-stellar gas dust clouds in the universe, which are divided into bright nebulae and dark nebulae according to their luminous performance, and bright nebulae are divided into diffuse nebulae, reflection nebulae, planetary nebulae and supernova remnants according to their origin and physical origin" Jiang Bing finished speaking in one breath, and after finishing speaking, he took a breath and asked in the surprised expressions of the two, "Does the teacher still want to recite the specific meaning of each nebula?"

"No need, I believe you should be familiar with this part, and I won't ask questions", Liu Xin was really surprised, she really didn't expect that Jiang Bing couldn't even see the concept of how to memorize the nebula on weekdays.

What was even more surprised than Liu Xin was Sun Lu, she felt like she was dreaming when she listened to Jiang Bing's recitation, Jiang Bing skipped class except for sleeping on weekdays, how could she memorize the concept of nebula so smoothly.

"Finally, let me ask you a simpler question, what are neutrons," Liu Xin asked.

This is the knowledge of the second year of high school, or what Jiang Bing talked about when he didn't come, Sun Lu was even more nervous than before, because Jiang Bing hadn't even heard of the name neutron.

"Microneutrons are neutral and are an ignorant elementary particle, and I can't remember the rest clearly," Jiang Bing said.

"It's okay, I really didn't expect that you can be so good if you don't study in class, I think you just owe a beating, if you listen well in class, your grades will definitely not be worse than Sun Lu" Liu Xin said, she no longer turned her pen, and said Jiang Bing with some complaints.

"Yes, yes, I will definitely listen to the lectures in class in the future, in fact, I am too lazy to study because the class leader tutors me after class," Jiang Bing said.

"It can't be like this anymore, you know."

"Yes" Jiang Bing shouted, making a saluting gesture that made Liu Xin laugh.

"Sun Lu, you are doing a good job, people like Jiang Bing who are not enterprising, opportunistic and slippery, can be taught very well by you, I am not wrong about you" Liu Xin praised Sun Lu.

Sun Lu was ashamed and didn't dare to answer.

"Then this lazy guy will be handed over to you in the future, I believe that you will be the same as before, urging him to study" After speaking, Liu Xin stood up, sorted out his clothes, and prepared to leave.

"I know," Sun Lu said, and then sent Liu Xin away.

"Hey, what's the situation with you, was that really you just now?" Sun Lu trotted back to ask Jiang Bing after sending Liu Xin away.

"Haha, I'm not very powerful, are you a little worshipful brother now, it's okay, brother is just a legend, you don't have to say anything like thanking the master" Jiang Bing said, he had just relieved Sun Lu's siege, and now he has to inch in.

"Get out, say it quickly!" Sun Lu smiled and changed her serious expression.

"Okay, okay, it's really a woman's heart, I read your book this morning, and it just happened to be in the book," Jiang Bing said.

"If it's really fake, you just read it once and memorize it."

"Of course, for someone as smart as me, it's not easy to memorize it after reading it."

"I have pi here, do you want to try it?" Sun Lu said.

"Then forget it, even if I talk faster for a while and a half, I can't finish memorizing."

"From tonight onwards, I will give you tutoring, and you are not allowed to run when the time comes" Sun Lu said, fortunately, this time Jiang Bing read the textbook in the morning, if it was next time, maybe he would not be so lucky, he was caught, Jiang Bing was not happy, she was even more uncomfortable, she didn't want to be said by Liu Xin to be a person who only had a momentary passion.

No one wants to stay at school at night, after all, who doesn't want to go home at night and have a good rest, except for those who are called nerds, are people like Jiang Bing who are tutoring.

After dinner, Jiang Bing, who had nothing to do in the hotel, came to the classroom, but somehow, he had no interest in reading at all, and he was like two people in the morning.

Jiang Bing ate quickly, and came to the classroom after eating early, and at this time, only a few classrooms in the entire teaching building of the third year of high school were still lit.

The agreed time with Sun Lu was seven o'clock, so Jiang Bing was not in a hurry to read, after all, there was still a long time to study after a while, if he finished reading the textbook, how would he spend the rest of the time.

So Jiang Bing clicked on his phone and watched the anime.

This is an anime from a long, long time ago, from Yamatai, an independent kingdom on the border of Yan and Huang.

At that time, the animation industry in Yama Taiwan was extremely developed, and countless amazing works were created, and the Clannad that Jiang Bing watched was also one of them.

Although Yamatai has a deep blood feud with Yanhuang, it has to be said that its country still has merits.

The ancient saying of Yan and Huang takes its essence and abandons the dross.

"Have you seen enough" Sun Lu hurriedly walked into the classroom, her mouth full of grease stains, and she looked like she had just eaten a big meal.

"OK, ready to start at any time" Jiang Bing put down his phone, turned it off directly and stuffed it into his pocket.

"Then let's get started," Sun Lu said.

"Wait, are you sure you want to start now?" Jiang Bing asked when he noticed that Sun Lu didn't notice the grease stains on his mouth.

"Of course, it's seven o'clock, and I have to go home early," Sun Lu said.

"You better look in the mirror first, I can't really learn from you like this," Jiang Bing said.

"What does it look like" Sun Lu took out a small mirror from the hole in the table and looked at her face.

"Ah" Sun Lu shouted, immediately closed the mirror, took out a wet towel from the hole in the table, and simply wiped the remaining oil stains on his mouth.

"Where did you just go, why don't you wipe your mouth and leave," Jiang Bing said, turning the book out of the ground and placing it on the table.

"Of course it's going to have a big dinner, hey, don't worry about it, let's start learning" Sun Lu immediately felt ashamed when he thought of the scene he had come all the way, so he changed the topic.

Tonight, Sun Lu did not let Jiang Bing review physics, but took out English, although Yan Huang occupies more than one-third of the territory of the human race, there are still many people who learn English.

Seeing this dense letter, Jiang Bing felt dizzy, and he was not stunned at all when he asked him to learn mathematics, Chinese and physics, but in English, Jiang Bing really hated it in his heart, and even a little creepy.

"Tonight we are words, this unit is fifty, two hours OK" Sun Lu said, she is very good at English, she is very famous in the whole school, tonight she took out her housekeeping skills, let Jiang Bing learn English.

"Ahh Wave... West... Jiang Bing looked at the twenty-six English letters at the beginning, and a single letter was buttoned up.

"What, Posid, you... You don't know English words" Sun Lu was shocked when she saw Jiang Bing's ABCD, she didn't expect Jiang Bing to pronounce the word as pinyin, she was caught off guard by Jiang Bing's play, she was so panicked, she promised Liu Xin to teach Jiang Bing well, but the scene in front of her was simply teaching a kindergarten child, and he was a person with a stupid brain, slow response, and not enterprising.

Sun Lu had a headache, and she had to start teaching from phonetic transcription first, and let Jiang Bing learn from scratch.

Somehow, Jiang Bing, whose brain is comparable to that of a scientist on weekdays, actually short-circuited, and he couldn't learn English.
