"What kind of books did you buy, didn't you just buy them yesterday, and what are you going to buy?" asked Wang Liuwu puzzled. Yesterday, Shen Tianwei didn't buy the full set of this semester's Wang Houxiong series at Tianyi Bookstore, why do you want to go now?

"Didn't I buy Mr. Wang's reference book yesterday, but today I'm going to buy "Friends of Mathematics". Shen Tianwei subconsciously blurted out.

"Is "Friends of Mathematics" the one edited by Tao Li of Jinling Middle School?" Wang Liuwuyi was stunned, and then asked.

"That's right. What's wrong, is there a problem?" asked Shen Tianwei.

"There's a problem? Of course there's a problem! Didn't you say I wouldn't buy the book if I killed you? Why did you suddenly change sex now? Wang Liuwu immediately asked.

Shen Tianwei, who was standing there, suddenly felt a little embarrassed, he seemed to have really said something similar, and this change in attitude seemed to come too quickly. It's amazing how much of an attitude change I can have in just one day.

But Shen Tianwei really wants to buy this book now! Because even he has to admit that the "Friends of Mathematics" edited by Tao Li is indeed better than Wang Houxiong's mathematics reference book, and it seems to be better than Wang Houxiong's in any aspect!

As for what is good, Shen Tianwei can't understand it for a while, but the experience of using it is different. "Friends of Mathematics" has a kind of magic that attracts you to keep looking down and slowly become interested in mathematics.

That's right, it's getting yourself interested in math, and that's the scariest thing about this book. Shen Tianwei now believes a little bit in the legend about Tao Li on the Internet.

"He bought it for me, okay? You see he painted my book like this, I still bought it new, and he can't pay me for a copy?" Chen Hui, who was still sitting in a chair, explained helpfully.

How could he not see Shen Tianwei's embarrassment, but if he didn't give Shen Tianwei a step at this time, he was afraid that he wouldn't dare to say too much in the future.

"Yes, I bought it for Little Ash, and you see I was careless, so I scribbled on it. Hurry up, if the book is gone in a while, but you are the only one who asks!" As he spoke, Shen Tianwei cast a grateful look at Chen Hui, and then ran outside the classroom.

"Why do you want me to buy books!" Wang Liuwu muttered quietly, but still followed Shen Tianwei.

After Shen Tianwei rushed out of the classroom, he rushed all the way towards Tianyi Bookstore, not because he was worried about the upcoming class, but because he remembered that Tianyi Bookstore seemed to have a few copies of "Friends of Mathematics" in total, and he was afraid that he would not be able to buy them if he was late.

When I ran to Tianyi Bookstore, the owner Huang Yiming was packing up his things and preparing to close the door and go home. On the first night of school, not many students would come, and it was still comfortable to go home on a cold day.

"Old ...... Boss...... Wait a minute. Shen Tianwei pinched his waist and said breathlessly.

"Aren't you the classmate who came yesterday, what's the matter?" Huang Yiming recognized Shen Tianwei at a glance that he had been here yesterday, so he asked with a smile.

"I want to ask, do you still have "Friends of Math" in your store? Shen Tianwei hurriedly asked.

"Of course there is, I took a dozen copies, and so far no one has asked except you twice. What, do you want to buy it?" said Huang Yiming with a smile.

"Hmm, please get me a copy. Shen Tianwei nodded hurriedly and said.

"The Friends of Mathematics in the sophomore semester, right? I went in and looked for it, and it was all put in the innermost part. Huang Yiming said as he walked into the bookstore.

"It's not Tianwei, why are you running so fast? Are you smeared with oil on your feet? But I'm tired to death. At this time, Wang Liuwu, who was following behind, finally caught up, and he couldn't breathe.

"You're too vain! Fortunately, run faster, or the bookstore would have closed. By the way, would you like "Friends of Math"? Or I'll buy you a copy too. Shen Tianwei said angrily.

"I don't want it, what do you want that?" replied Wang Liuwu without even thinking about it.

"Of course, it's for studying! Let me tell you, this book is really easy to use, you won't regret it!" Shen Tianwei said with an oath.

"I don't know who said this book is not good. What's the matter, now you want to give it to me again?" Wang Liuwu rolled his eyes and said.

"That's called this time, that time! What do you know? At that time, I didn't know whether this book was good or bad, and I evaluated it based on my own subjective assumptions, but now I know that this book is very useful, why didn't I buy it?" Shen Tianwei defended.

"I'll just say it, this fucking must be you who want to buy this book, and you actually let the little gray ash take the blame!" Wang Liuwu said immediately.

"Come on. I can't tell you about it. Boss, here are two copies of "Friends of Mathematics"!" Shen Tianwei immediately shouted into the bookstore.

"No, who told you I want it?" asked Wang Liuwu hurriedly.

"Count me on your business! It's only a few dozen dollars anyway. Let me tell you, it's too late for you to thank me in the future?" Shen Tianwei pouted and said.

"I'm going to thank you now! It's just a book, how can it be as exaggerated as you say. Wang Liuwu said disapprerovingly.

"This is your book. It's been almost a week since I got it, and I've finally sold two copies. Huang Yiming said with emotion.

"Maybe in a few days, the book will be in demand. Shen Tianwei said with a smile while paying.

After taking the book, Shen Tianwei and Wang Liuwu said goodbye to Huang Yiming and walked in the direction of the classroom.

"Take the book, remember to read it, the book has its own golden house!" The books have been bought, and when they go back, the two of them are not in a hurry. Shen Tianwei handed a copy of "Friends of Mathematics" to Wang Liuwu as he walked.

"What a golden house. It's all fake, don't try to lie to me. Wang Liuwu took the book and said angrily.

"You'll know if what I'm saying is true. If you don't watch it, you'll really regret it. Shen Tianwei patted Wang Liuwu's shoulder and said in a tone from a passerby.

When the two of them arrived at the classroom, everyone was looking at the book seriously, of course, there were many people pretending, anyway, there was no teacher there, so take the book to cover it, and you can play with your mobile phone.

After Wang Liuwu returned to his seat, the same table was playing with his mobile phone selflessly, and when he saw Wang Liuwu sitting down, he just glanced up, and then hurriedly said, "Liuwu, do you want to eat chicken? Let's open the black in four rows in a while." ”

Wang Liuwu was about to take out his mobile phone to agree, but when he saw the newly bought "Friends of Math" on the table, he hesitated for a moment, and then replied, "You guys play first, and I'll come back later." ”

After silently putting away his mobile phone, Wang Liuwu picked up "Friends of Mathematics" and began to look through it slowly.
