Du Xiaozhou happily put the two rusty copper coins in front of Lin Mumu and Liu Yuanyuan.

Liu Yuanyuan nervously pinched the coin and looked closely.

"Have you seen enough? Nerd babes? Fang Tianyong sneered: "We're in class now, but there aren't so many people waiting for you." ”

Lin Mumu chuckled: "From your words, I know that you are very unprofessional, as a professional antique appraiser, the biggest taboo is to urge words."

If you are a seller, it means that you have a weak heart. If you are a peer, it means that you have ulterior motives.

It's written in these books, why, didn't Fang read the books carefully and didn't listen to the teacher? ”

Lin Mumu is good-tempered most of the time, provided that she doesn't provoke her, once someone provokes her, her good temper will all be reined in.

Like now.

Lin Mumu suddenly asked Liu Yuanyuan: "How do you feel?" ”

"This one is too heavy. I can't see the other one. Liu Yuanyuan replied.

Lin Mumu took the one that Liu Yuanyuan said was wrong in weight, took it in his hand and weighed it casually twice:

"This weight is not right at all, the real ancient coins are made of exquisite materials, the copper is delicate, due to the age, the internal composition has changed, the weight will be greatly reduced, and the copper used in the counterfeit coins is poor and thicker.

It's written in the book, so this one is a later imitation. ”

Then she picked up another coin with a pencil, but she didn't have it in her hand, and said:

"And this one, although the weight is right, and it is also a copper coin, yes, it is not. One way to do it is to bury it in piles of chemicals, and possibly even in thatched huts, so that it can become yellow rust.

Therefore, when we identify, in order to prevent the infection of viruses and other things, it is best to observe before starting.

It is said that there is a golden house in the book, which seems to be true. Student Fang, are you still satisfied with the answers that I, a nerd, found in the book? ”

Lin Mumu said, and with a pencil in his hand, he picked up the two copper coins to Fang Tianyong.

Fang Tianyong subconsciously took it, and then the expression on his face became more and more ugly, he didn't even care about the copper coin, said that his stomach hurt, and hurriedly ran to the toilet.

From his disgusted and disgusting expression, Du Xiaozhou also guessed that Lin Mumu said another copper coin, I am afraid that it was really through the means of burying the thatched house in the legend.

Thinking that he had carried the two copper coins in his arms like babies before, and tried them with his tongue, Du Xiaozhou was nauseous, and hurriedly ran to the toilet.

"Let's take a five-minute break." Although it was not time for the end of class, the teacher was very considerate and gave them a break.

Lin Mumu, Liu Yuanyuan, An Xiaoqin, and Chen Fangya also went to the bathroom to wash their hands. Although they didn't touch the copper coin with their hands, after all, it rolled on their table, and it was disgusting to think about it.

"Lin Mumu, you are simply amazing. Didn't disgrace us professionally! In the bathroom, Chen Fangya patted Lin Mumu's shoulder excitedly.

"Look over there."

Fang Tianyong and Du Xiaozhou just came out of the bathroom, Fang Tianyong was fine, Du Xiaozhou had become a weak puppy.

"Poof, I'm laughing to death." Chen Fangya is a lively character, standing at the door without fear of hatred, learning Du Xiaozhou's previous actions, chicly taking out two coins from his arms, and learning Du Xiaozhou's voice:

"This is the coin I found in the bathroom~~~ I wonder if it's something that my ancestors used to go to the toilet?"

Fang Tianyong and Du Xiaozhou ignored her, glanced at them hatefully, and hurried back.
