"The reciprocal of infinity is equal to infinitesimal and the reciprocal of infinitesimal is infinitely large. When it is not equal to 0, because the reciprocal only makes sense at this point, and the infinitesimal quantity is possible to take 0. Everyone must remember!" Advanced mathematics is a subject that gives me a lot of headaches, and I am listless, holding my cheeks, listening to the teacher's lectures.

Finally, the bell rang for the end of class. Several students ran out of the classroom without waiting for the teacher to announce the end of class.

"Niuzi, it's noon, shouldn't you buy an order for your mistakes in the past two days? Sun Wei said sneeringly, and the brothers looked at me expectantly after hearing it.

"Okay, okay, I'll invite a few brothers to eat Sichuan County snacks. I reluctantly agreed.

"Let's go, let's go to the tooth sacrifice. Zhu Chen also joined in the fun.

Walking out of the school gate, we talked and laughed.

"By the way, Brother Guang, yesterday's matter of Namo was settled, right?" I asked.

"You're embarrassed to say, I don't know if it's good or bad, but you took a few pieces anyway. It's you, what happened yesterday, and you ran away as soon as you smoked it. Brother Guang said angrily.

"Hey, don't mention it, Fa Xiao wants to buy an object, I'm not sure, I'm afraid that he will be blind, so I'll go and see it." I mumbled.

"So what happened in the end, is it really fake?" Sun Wei picked up the leak with me, and he also became interested in Taobao.

"I guess it's true. "I don't want to talk about bronzes, after all, buying and selling bronzes privately can break the law.

"Niuzi, you are so good at appreciating treasures, why don't you join the club of our school for appreciating treasures?" asked Song Jun.

"And the treasure appreciation club?" I was a little surprised, the chorus club, the dance club, all kinds of ball clubs, even if it was the chess and card club, Beixin Academy, I knew it, I had never heard of this treasure appreciating club.

"We don't have a good news, and we are Song Junlu Ziye. Sun Wei said in a weird way.

"What does it have to do with me, Zhu Chen told me. Song Jun shouted that he was wronged.

"I also heard from Nanli. Zhu Chen didn't admit himself.

We cast strange glances at him in understanding.

"Tell me, the relationship has been so close lately, what's the situation? You talk about playing basketball every day, are you blinded by us?" Brother Guang teased.

"Oh, no, I just mentioned it by accident, he applied to join the club. Zhu Chen dodged Brother Guang's arm on his shoulder and said.

"There must be something wrong with you two. Why don't he tell you, not us? "Hu Shikao's honest people are honest and very lethal.

I couldn't help but laugh, and seeing that Zhu Chen was a little unsure of what to do, I quipped: "King Snoring, why are you so sour." If you have the ability to learn from the Song army, the sword will conquer the city before it is unsheathed. ”

"Hey, I didn't look for anyone and didn't mess with anyone, why did you bring me with you. Song Jun said angrily.

"You guys be serious, don't be old men and women..."Sun Wei interrupted us, and then Song Jun shot back: "Anyway, this matter has nothing to do with you. ”

We laughed, and the more we spoke, the more heartbroken it became, and our friendship grew stronger and stronger as we hurt each other.

"Grandpa, your grandson has called you. "This is the ringtone of my funny phone that I just changed yesterday.

"Hey, Dad. I picked up the phone and felt that something was wrong, and Brother Guang and the others were already laughing like crazy on the road, attracting strange observations from the crowd passing by.

"Mr. Yang called, and invited a few experts from the Palace Museum and experts in this area, and wanted to see the ink this afternoon. The voice on the phone was a little hurried.

"I'm in such a hurry, I still have class this afternoon. I scratched my head a little, it stands to reason that Brother Yang is a life-saving benefactor, and I should have done everything I could, but it's not a good thing to start skipping classes just after college.

I picked up the phone and asked my dad what had happened in the morning. Brother Guang's mobile phone also rang, and it was Jin Feng's father who called directly.

Brother Guang immediately restrained his smile and pressed the answer button respectfully.

"Hey, hello uncle, I'm Shu Guang. Brother Guang's tone was very pious, and he didn't have the usual smug at all.

"Xiaoguang, I just called Jinfeng's girl, and I didn't answer for a long time, so I called you. A mid-term voice came from the phone.

"Maybe Feng didn't have her phone with her, do you have anything to do? I'll go find her later?" Brother Guang asked tentatively.

"Oh, no, just ask. Uncle Jin said, "There is a student named Niu Ben in your school, have you heard of it?"

Brother Guang was stunned, turned his head and looked at me in surprise, I was puzzled, and continued to talk to my dad on the phone.

"Yes, Niu Ben is my roommate. Brother Guang said.

"He's your roommate?" the voice in the microphone was a little excited.

"Yes, uncle, he's right next to me. Brother Guang said very calmly, and then kept looking at me.

"Oh, Xiaoguang, your classmate is amazing, a few days ago, I missed an ancient painting, and recently found Li Tingqimo, quick, give the phone to your classmate." Thanks to the loudspeaker of the mobile phone, I can also hear it clearly next to me, and I am busy talking to my dad and hanging up the phone.

"Uncle, wait a minute. Brother Guang covered the microphone of the phone and instructed me: "This is the old man of the Jinfeng family, I want to find you, you are good, don't give me a moth." Then, don't forget to wave your fist and show off your muscles.

I was very helpless, although I didn't know when this uncle I had never met looked for me, I still picked up the phone.

"Hey, Uncle Kim, hello, I'm Maverick. "I was a little nervous.

"Oh, Mr. Niu. I didn't expect..."I was blindsided when I heard this, and hurriedly interrupted, "Uncle Jin, Uncle Jin, I'm a calf, not a cow teacher." ”

Uncle Jin smiled and said: "Little cow, you don't know yet, now you have found out about Li Tingqimo, the circle has been in an uproar, plus you have picked up the bee-eater map before, everyone in the circle also knows, you are now a hot celebrity in the collection circle! With achievements, it is natural to be called a teacher. But I never thought that you, Feng'er and Xiaoguang were classmates..."

"Uncle Jin, you're joking, I'm a beginner, how can I be qualified to be a person in our collection circle. Even though I knew it was complimenting me, I was still embarrassed and busy.

"Xiao Yang said, I can see Li Tingqimo this afternoon, no problem, I invited all the teachers over. Uncle Kim said.

"Your teacher?" I was a little surprised, and then I became excited, "Uncle Jin, I remember, your teacher is the master of Chinese studies!"

"yes, so, I'm going to call to make sure that the old man is very concerned about this. Uncle Jin said.

"No problem, no problem, I just answered my dad's call, and at two o'clock in the afternoon, I'll see you at the teahouse that Brother Yang said. Rest assured, I'll be there early. I said excitedly. For that master of Chinese studies, I admire it from the bottom of my heart.
