"Huh? That's ...... Done?"

Xu Shiya hadn't reacted yet, looking at the book that was full of writing, standing stupidly in place, a little stunned.

"Of course it's done, you're still too slow!" Lin Fan rolled his eyes.

"It's not...... I ......" Xu Shiya waved her hand again and again, wanting to explain, but her tongue was knotted and she couldn't say a word.

Seeing Xu Shiya's stunned expression, Lin Fan stretched his waist, subconsciously looked up at the time, and couldn't help but feel embarrassed: "I'll go...... It's really slow enough, it took six hours for just such a question, my god, but then again, this question is really fucking troublesome!"

"Uh......" Hearing Lin Fan's words, Xu Shiya suddenly sweated, on this question, she has been studying in college for four years without a clear idea, and so far she still looks at this question as if she is reading a book from heaven.

At home and abroad, there are some experts and professors who have been studying this question all their lives, but so far I have not heard of anyone who can have a method of solving it.

But now, it only took Lin Fan six hours to finish this question, and it was still too slow, Xu Shiya was a little speechless, and she didn't know what to say.

"Report!" Suddenly, a shout outside startled Xu Shiya, she came back to her senses in a daze, and hurriedly spoke: "Come in!"

The door was pushed open, and Wu Qiang walked in.

"Is there something wrong?" Seeing Wu Qiang, Lin Fan and Xu Shiya were all confused.

"Hmm...... Teacher, our homeroom teacher asked me to call Lin Fan back to class!" Wu Qiang stood outside the house and said cautiously.

"Head teacher, Teacher Qiu, haven't I already greeted her, why is she still urging?" Xu Shiya frowned, a little puzzled.

As early as when Lin Fan was doing the question before, she ran out to say hello to all the teachers according to the next class schedule, saying that Lin Fan might not be able to go to class, but she didn't expect the head teacher, Mr. Qiu, to come to such a show at this time.

"What, Mr. Xu, anyway, the question has already been made, so I'll go first!" Lin Fan said and walked directly outside.

"Hey, you wait......" Xu Shiya still wanted to stop it, but after thinking about it, she waved her hand, "Okay, you go first, and we'll discuss this question when we have time!"

"Okay, goodbye, Mr. Xu!"

After saying hello to Xu Shiya, Lin Fan followed Wu Qiang and quickly went to the class.

Inside the house, Xu Shiya looked at the process of nearly two books in a daze, whether this answer was right or not, she didn't know, the answer process above was too floating, and it was too troublesome, and she couldn't tell if it was the right answer.

After thinking for a while, Xu Shiya took out the phone and pressed a number, and after a while, a kind voice came from the phone, "Xiao Xu, how is it? It's okay to be a teacher in Yunshan No. 1 Middle School!"

"Hmm...... Fortunately, Huang Lao, how are you doing? Your body is still strong! Usually pay more attention to exercise!"

"Hahaha...... It's rare that your little girl is still so concerned......"

After being polite with Professor Huang for a while, Xu Shiya spoke: "Old Huang, do you remember the question I told you before?

"Oh, what did you say, what's wrong?, the results of the research?" Huang Lao asked with a smile, his tone relaxed and unconcerned.

"Hmm...... It was one of my students who wrote out the answer, but I'm not sure if it's the right answer, so I'd like you to discern it!"

"What? one of your students?" Hearing this, Huang Lao laughed, but still nodded again and again, "Okay, okay, you can send it to me, I'll have time to take a look!"

"I'll send you an email, you can take a look now, I'm in a hurry here, Huang Lao, please!"

Xu Shiya begged, Huang Lao nodded with a smile, "Okay, okay, I'll watch it now!"

"Uh-huh...... Thank you Huang Lao!"

Hanging up the phone, Xu Shiya did not hesitate, immediately took out her mobile phone and took pictures of those answers page by page, a total of more than 20 photos were taken before it was over, arranged in order, and sent it directly.

After a busy job, Xu Shiya was still not at ease, so she called Huang Lao again to urge, and only then did Xu Shiya breathe a sigh of relief when Huang Lao confirmed that he was watching.

Unconsciously, it has been a long time since the document was sent, but there has not been a reply from Huang Lao's side.

Xu Shiya waited anxiously, and wanted to call to urge, but she was afraid of disturbing the other party, so she could only pinch her mobile phone and paced in place.

I don't know how long it took, suddenly, a pleasant ringtone rang, Xu Shiya's eyes lit up, and she immediately grabbed the phone to answer the sound.

"Little ...... Xiao Xu...... You...... You...... You ......" On the other side of the phone, Huang Lao was panting heavily, and he didn't say a word for a long time.

Xu Shiya was frightened, and hurriedly cared: "Huang Lao, don't worry, speak slowly, speak slowly!"

"Whoa......" After a burst of heavy wheezing on the other side of the phone, Huang Lao spoke with difficulty, "That...... Xiao Xu...... The ...... to answer this question Student...... Keep ...... Be sure to keep it...... Wait for me...... I'm going to see him! This is the hope for the future of the country......"

"Huh?" After saying this, Xu Shiya was stunned, and in an instant, her eyes brightened again, "Huang Lao...... Are you saying that he got the answer right? Hey, Huang Lao, you speak!"

Xu Shiya grabbed the phone and was extremely anxious, and at this moment, a pleasant voice came, "Shiya, don't say it, grandpa has a myocardial infarction, I have to send him to the hospital quickly! Grandpa is old, don't use these things to stimulate his old man in the future! He can't stand it!"

"Huh?" Hearing this, Xu Shiya's face turned pale with fright, and she swallowed fiercely, "Huang Lao...... Huang Lao, he's okay!"

"It's okay, that's it, hang up first!"

Hung up the phone, listened to the busy beep on the phone, and then looked at the difficult question on the table full of books, Xu Shiya's heart was shocked inexplicably, and she couldn't say a word for a long time.

On the other side, as soon as he and Wu Qiang walked to the door of the classroom, they were stopped outside by the head teacher, Mr. Qiu, "What are you doing?"

Lin Fan straightened his waist and replied with his chest straight, "Teacher Xu has a math problem to discuss with me!"

"Hah...... Just you?" Hearing this, Mr. Qiu laughed as if he had heard the funniest joke in the world.

At the same time, Yang Dong and Xue Meiqi and others in the class also sneered.

"Teacher, he skipped class if he didn't want to go to Chinese class, and what did Mr. Xu ask him to discuss math problems, he really can't lie!" Hao Pengfei also smiled, laughing extremely proudly, looking at Lin Fan's eyes full of provocation.

"Fuck you, when class ended, Mr. Xu shouted at him in front of the whole class, didn't you hear it?

"Fat Tiger, who the are you slapping the table with and glaring at me?Stand up for me?" Mr. Qiu, the head teacher, was furious, glaring at Fat Tiger and yelling.

"I ......" The fat tiger blushed and got up directly from his seat.

The head teacher looked at Fat Tiger, no longer paid attention to him, and turned to look at Lin Fan, "Blatantly skipping class for six hours, this is the second time, I won't say anything if I didn't catch me last time, this time I was caught by me, what else do you have to say?"

Lin Fan smiled and shook his head, "There's nothing to say!"

Hearing Lin Fan's words, the head teacher became even more proud, and circled around Lin Fan, "Let's talk about it, how should I deal with you this time?

"What kind of parent is it, just expel it, what is the effect of this kind of black sheep in addition to lowering the average score of our class!" Hao Pengfei sneered.

"That's it, teacher, don't hesitate any longer, expel directly, I raise my hands in favor!" Xue Meiqi was triumphant.

And looking at their appearance, Lin Fan smiled, "Teacher, I want to ask, why did you expel me?"

"Hah...... Why did you expel you? Are you embarrassed to ask? Look at your academic performance, and then look at what you have done, I won't talk about blatantly skipping class this time, I found a gangster outside the school to beat Yang Dong at the school gate two days ago, do you think I don't know? I can fire you just because I fought and skipped class!"

There was a smile on the corner of Teacher Qiu's mouth, but the fat tiger on the other side had blood-red eyes, and he slapped the table hard with a snap, "Are you your spicy next door?" Obviously, it was Yang Dong who looked for Zhao Hu and they beat Lin Fan, but they were beaten by Lin Fan, and now you are told that it was Lin Fan who beat Yang Dong? There is a teacher like you in the world?"

"Fat Tiger, shut up for me!" Teacher Qiu was furious, his eyes were staring at Fat Tiger, his chest was rising and falling, and the whole person was extremely angry.

"Shut up, than your Malegobi mouth, draft, Lao Tzu has long been fed up with your bird's anger, don't you read, draft!" After the fat tiger finished speaking, he kicked over the desk, his eyes were full of fire, and he looked directly at Teacher Qiu.

"You...... You ......" looked at the fat tiger, Mr. Qiu trembled with anger, panting heavily, unable to say a word for a long time, for a long time, Mr. Qiu finally relieved his breath, staring at the fat tiger is roar that shook the world, "You get out of me!"

"Hahahaha...... Get out, I'm afraid of you!" the fat tiger sneered, didn't even think about it, and walked directly to the outside of the classroom.

When he arrived in front of Teacher Qiu, the fat tiger also snorted at her, suddenly, his mouth wrinkled slightly, he took a deep breath, his throat made a thick sucking sound, and then, his mouth made a muffled sound, and then he looked at it, and a mouthful of sticky old phlegm sprayed directly on Teacher Qiu's trouser leg.

"Hiss......" At the moment when this mouthful of old phlegm spewed out, the whole class gasped, and for a moment, the whole class was silent, and they all looked at the fat tiger with a shocked face.

"You...... You ......" Looking at the old phlegm on his trouser leg, Mr. Qiu went crazy with anger, and the whole person was panting heavily, and suddenly, with a roar, he rushed directly towards the fat tiger.

"What do you want to do?" At this moment, Lin Fan moved, one hand directly grabbed Teacher Qiu's wrist, and a pair of eyes glared at her fiercely.
