At this time, Tian Xiaoyu didn't have time to close the zipper of her coat, carried a bag, and ran around the campus, forming a unique landscape, and she was not fast enough, and she couldn't wait to step on Nezha's Hot Wheels. Finally panting and running to the classroom, looking up at the time, fortunately, there are still two minutes before the class starts, but the teacher has already stood in front of the podium and is ready to speak, in order not to attract the attention of others, Tian Xiaoyu hurriedly entered through the back door and sat down in the back row.

Sit still, breathing evenly, while looking at the students in the front row and the teacher on the podium. The teaching classrooms are all step-type, the further back the row, the higher the terrain, at this time Tian Xiaoyu sat at the back, there was a Jesus-like perspective, and he unconsciously straightened his back.

Listening to the class, I always unconsciously glanced at Fang Yu in front of me...... Although Tian Xiaoyu has warned herself several times in her heart, the more she warns, the greater Fang Yu's position in the perspective, just like when she was doing physics papers in the college entrance examination, she kept singing in her head about her sister sitting on the bow of the boat! The more I want to stop it, the louder the song becomes, sister, you take the bow of the boat~~~ Brother, I'll walk on the shore...... In the end, the physics that I have always been good at only scored 118 points! Thinking of this, Tian Xiaoyu was very angry and hated this song very much, but now that he thought about it, he unconsciously hummed it in his head......

Damn it! Tian Xiaoyu couldn't help but hit the table with his fist, and several classmates who were sitting close to him were startled by the sound of the beating, and turned their heads to look at her, Tian Xiaoyu saw this and hurriedly hunched his waist and shrunk his neck, nodding to them to apologize.

"Okay, let's answer that classmate!" From the front podium came the voice of the teacher.

The classroom that was still a little whispering just now suddenly quieted down, and the students sitting below didn't dare to move as if they had been pointed, worried that it was they who clicked, and of course Tian Xiaoyu at this time was also like this, looking down at the books.

"Hey, don't look down, just the one sitting in the back row, everyone just looked at your classmate, I think you should know the answer, otherwise why would everyone look at you?" The instructor said "kindly".

Tian Xiaoyu seemed to have been relieved, slowly raised her head, and happened to meet the teacher's gaze, oh my God, she was shocked, is it me? The teacher's affirmative gaze answered the question in her heart.

Tian Xiaoyu stood up slowly, and everyone sighed softly when they saw that the unlucky guy had been identified, and the tense classroom atmosphere just now relaxed again.

Who am I?

Where do I come from?

Where am I going?

What did you just ask?

A series of question marks spread from the bottom of Tian Xiaoyu's heart to his face, and this confusion made the scene more embarrassing.

"Teacher," Tian Xiaoyu blinked his eyes, bit his lip again, and plucked up his courage to say, "I'm very sorry, I was a little distracted just now, and I didn't hear your question clearly......"

The instructor cupped his eyes, nodded and smiled, "Oh, that's right." Then let me ask again, what are the sources of error in the field of measurement? ”

Tian Xiaoyu heard the question clearly, it was not difficult, but he subconsciously wanted to flip through the book in his hand, and then thought that he didn't know which page he was in, so he gave up the way of turning the book, sorted out his thoughts, synthesized it from his work experience, and said softly: "Well, probably, there are principle errors, manufacturing errors, operational errors, etc." ”

After listening to Tian Xiaoyu's words, the teacher nodded and said, "Well, that's good." After flipping through the book, he looked up again and asked, "Then I ask you again, how to avoid errors in principle?" ”

Tian Xiaoyu, who just wanted to bend down and sit down, listened to the teacher's question and stood up straight again, and replied: "Well, maybe, you can study the principle error law to avoid it, and also, you can use error compensation." ”

"Okay, well, sit down!" The instructor nodded and continued, "This classmate, you answered very well!" Be confident, when answering questions, don't be possible, probably, pat your thigh, say it with certainty, even if it's wrong, be confident! As he spoke, the teacher lifted his right leg up and slapped his thigh hard.

Everyone laughed "coaxing", Tian Xiaoyu looked at the teacher and nodded with a smile, after sitting down, gratitude spread out of her heart, because she has not been a particularly confident person, and the affirmation of others for her can always be exchanged for her very moved. Unconsciously glanced at Fang Yu again, Fang Yu turned his face sideways and did not look at Tian Xiaoyu, but there was her in the afterglow, and Liu Wei next to him turned around and threw a big wink at Tian Xiaoyu, Tian Xiaoyu saw this and grimaced.

The two classes passed quickly, and the bell rang for the end of class. Tian Xiaoyu packed her mobile phone and books into her bag, picked up her bag and thought about whether to go back to the dormitory or go to the study room, but today is Monday, Zhu Yue may not have time to meet his friend application on the Internet, so it is useless to go back to the dormitory, so let's go to the study room first, review more today, and review less tomorrow!

Just walking slowly, I heard someone behind me calling me, it turned out to be Zhang Ying and her boyfriend Wei Yang.

"Yo, Tian Xiaoyu, I feel like I've lost weight again! It's like a little girl of sixteen or seventeen! Wei Yang praised Tian Xiaoyu like honey in his mouth.

Wei Yang is sweet-mouthed, otherwise how could the girl be so popular and still be able to circle Zhang Ying. After listening to Wei Yang's compliments that he didn't know whether it was true or not, and most of them were fake, Tian Xiaoyu smiled helplessly at Wei Yang and said, "God, I've been busy reviewing recently, it's not bad if I'm not a few years old!" He pounded Zhang Ying with his arm again, "Wei Yang's mouth is like smearing honey, it is easy to attract bees and butterflies, you can be careful!" ”

Zhang Ying took Wei Yang's hand and shook it, and said with a smile: "Just let him try to attract bees and butterflies, and see if he doesn't hit him!" ”

Wei Yang was aggrieved and spread his hands, "Hey, it's hard to be a man!" Don't say bad things, don't let good things go! ”

Tian Xiaoyu suddenly remembered that Wei Yang, as the eldest brother of the class, often led other students to play games, and he didn't know how much he knew about Bitcoin, so he straightened up and asked, "By the way, Wei Yang, I want to ask you something." ”

Zhang Ying saw that Tian Xiaoyu was about to ask about business, so she pulled Wei Yang to Tian Xiaoyu's side, walked to the side by herself, and gave the two of them space to talk.

Sure enough, she is a model of a good wife and mother! Tian Xiaoyu said in her heart.

"If you have something, please tell me, brother, I must know everything, and I will say everything!" Wei Yang waved his hand and said arrogantly.

"Well, you guys who play games a lot, do you know Bitcoin?" Tian Xiaoyu asked tentatively.

Wei Yang frowned and thought for a while, and replied, "Bitcoin? I don't know! He raised his head again, scratched his head and thought about it for a while, and then said, "Isn't it, that, when playing a game, hang up the server, how many coins will be mined out?" ”

"That's right! That's it! Tian Xiaoyu jumped up excitedly and quickly replied.

Zhang Ying and Wei Yang were happy when they saw Tian Xiaoyu's excitement.

"What's wrong? What's the use of that thing! Wei Yang said.

Oh, my God! Tian Xiaoyu's heart was already stormy, it was useless, how could it be useless! Ten years later, it's 210,000!! God has eyes! I, Tian Xiaoyu, am going to get rich!!

Tian Xiaoyu exhaled, adjusted his emotions, and said: "Well, that's right, my brother has a hobby of collecting this coin, and he wants me to help collect it." ”

"Oh, this bitcoin is useless, you give an account, and it will be given to you directly." Wei Yang said.

"Hey, I can't take it for nothing, I was entrusted by someone, and he said that he wanted to buy it, so I will buy it and transfer it to him." Tian Xiaoyu said righteously, saying that he was about to believe it, and at the same time he was very embarrassed in his heart, after all, it was a lie......

"That's okay, it's not much anyway, just watch it!" Wei Yang nodded and said, "Then I'll go back and ask you and see how many there are." ”

"Okay, okay!" Tian Xiaoyu pursed her lips and said with a smile: "Thank you, brother-in-law!" ”

"Hey!" Zhang Ying couldn't help but pat Tian Xiaoyu's shoulder with a face full of shame, and said with disgust.

"Haha!" Tian Xiaoyu laughed and said, "The eldest sister is still shy!" Then he waved his hand and said, "I'm going to the study room, bye-bye!" ”

"Review well!" Wei Yang and Zhang Ying admonished.

Tian Xiaoyu waved his hand and walked happily to the study room, feeling uncontrollably excited, mixed with guilt, and feeling that it was really difficult to do business......

Jumping into the study room, but saw someone sitting in his seat, this back is too familiar to be more familiar, Fang Yu.
