It's just that this jade coin is really exquisite, and the cork bag is carefully made, it can be seen that at least this jade coin is an important thing for the girl in the water shirt, or an important relative.

When Zhang Jingtao asked to take a look, the girl in the water shirt did not throw the jade money over, but walked lightly, and handed the jade money to Zhang Jingtao with a smile under the veil.

At that moment, it seemed that everyone had seen something incomparably beautiful, and the melodious voice made people want to listen to it, even if the girl in the water shirt was still fighting without mercy before.

For this reason, the men present were a little jealous that Zhang Jingtao could receive this girl's gift like this.

Zhang Jingtao was also stunned for this girl's temperament, and then came back to his senses, took off the jade money in his hand and took off the cork sleeve to take a closer look.

This jade coin, the gold in the middle is engraved with the words 'cents', and there is nothing else.

After a pause, with the ability to call traditional Chinese medicine, Zhang Jingtao felt that the money should weigh 5 grams.

It's just that when Zhang Jingtao looked at the exquisite jade money, the girl in the water shirt said: "Since the jade money has been taken out as a lottery head, this copper coin made according to the jade coin is also together, they are a set, first made the appearance of the jade coin, and then according to the appearance of the jade coin, and made the mold of this copper coin, only to make this mother coin." ”

As he spoke, he handed over a fine copper coin with a square hole.

Mother money, talking about the first copper coin made after the mold of Fan Qian was opened.

Then the copper coin will be trimmed, or welded with some materials, or some materials will be removed, and after the ideal mother coin is obtained, a new mold will be made according to the mother coin.

In other words, this set of two coins is actually a mother coin.

It's just that this set of mother coins is too exquisitely made, and for this reason, the copper mother money has not been repaired.

If you look closely, this mother coin looks very much like a copper coin of the Qin Kingdom, but it is not the same size and color.

Because this copper coin is made according to jade coins, it is naturally only 2.5 centimeters in diameter and 1 centimeter thick, of course, this 1 centimeter is still 1 millimeter in modern people's opinion.

In particular, the color is very similar to modern coins, except that it is not a steel coin, but a copper coin.

In the middle of the copper mother coin, the hole that is one centimeter square is open, and after checking it with his hand, Zhang Jingtao feels that the weight of this copper mother coin is 4 grams, which is 1 gram lighter than the 5 grams of jade mother money.

On this copper mother coin, it is engraved with the words "half two" that later generations believed.

However, these two characters are standard Chinese simplified characters, and, according to the principle of starting from left, Zhang Jingtao believes that these two characters are fundamentally 'two halves'.

You know, this money only weighs 4 grams, what does it have to do with half a tael?

"This Gen is a set of private money made in private, right? Where among the vassal states are coins with a diameter of 2.5 centimeters? Duan Yu on the side couldn't help but show off his knowledge.

Zhang Jingtao took a closer look at this set of mother money, and his unmathematical knowledge suddenly became clear, and his heart beat faster.

But he only asked Duan Yu: "If I use this set of mother money to exchange some better lottery heads with you, will you change them?" ”

Duan Yu sneered: "Don't dream. ”

Zhang Jingtao asked Ximen Fox again: "What about Ximen Gongzi?" You must have a lot of good things in your home. ”

Ximen Fox also took the opportunity to show off his knowledge, and said with a smile: "This is probably a certain sect's military talisman, yes, one set is two, and they can be compared with each other, but unfortunately, what do I want to do with thousands of troops?" So I'm sorry, but this set of money has no value in my eyes. ”

Jing Jian didn't need Zhang Jingtao to ask again, and said, "Don't be verbose! In my opinion, this is just a step down for you, how much is it worth to study this set of antiques? ”

Zhang Jingtao ignored it, and asked the girl in the white dress again: "Beauty, I think you might as well use your sword as a lottery, but this set of mother money is for you to play." ”

The girl in the white dress was simply dismissive of it, and she didn't want to answer, but she seemed to think that why was this kid so brazen and wanted her sword?

The girl in the white dress snorted lightly and said, "It's really a poor habit of seeing money's eyes, and trying to make me lose my weapon, it's really whimsical!" Hum! Do you want this jackpot? Don't just fuck off! ”

Zhang Jingtao hooked the corners of his mouth, smiled lightly, and said, "Okay, just use this set of private money as a lottery head." ”

He said to the girl in the water shirt: "They don't know the goods, don't you say?" ”

The girl in the water shirt was interested in her beautiful eyes, glanced at Zhang Jingtao, and replied, "Zhang Zheng is really a little funny." ”

I don't know why she said that.

Zhang Jingtao didn't know, but saw that the copper mother coin could also be stuck into the back of the cork, so he stuck it on and returned it to the girl in the water shirt.

It's just that when the hand was repaying the money, he deliberately touched the hand of the girl in the water shirt.

The girl in the water shirt didn't seem to be aware, but when she put away her mother's money, it was a little too fast, so fast that she seemed to be a little flustered, and when she raised her eyes and saw Zhang Jingtao smiling at her, her eyes drooped, and she was a little dodgy.

Since the lottery has decided, everyone does not say much.

The study room of Ximen Mansion is indeed a good place to discuss swords.

This study is not an ordinary study, but it is a large square martial arts arena, with a thin wooden wall on the outside, a white paper partition wall on the inside, and one of the inner walls is made like a shadow wall, which is also called the frame wall.

On this inner wall, there is a big word 'sword' written on it.

Looking at the martial arts arena again, half of it can be used to practice martial arts, and half of it is a square platform with a square circle.

These square tables were covered with white paper, and a brush the size of a long sword was placed on a huge pen holder on one side, and the ink was ready-made, and it was packed in an ink bowl on one side.

"On the sword, it is better to write the sword first, from the calligraphy, you must be able to see who has a deeper understanding of the sword, which is also the basis of our competition." When the girl in the white dress saw this situation, her eyes lit up.

You must know that the paper, the pen and ink are all good things, if you love calligraphy, I am afraid that you will have itchy hands at the first sight.

Ximen Fox is the same, but he is not in a hurry, he walked to a low platform, but said softly: "Incense!" ”

There are Yahuan around to smell the wind, and on an incense stand in the middle of the hall, the sandalwood in a delicate moire incense burner is lit.

"Clean hands, clean face!" Simon Fox said again.

A group of maids came in and brought a basin of water to the people in front of the desk.

Everyone is not too cumbersome, if this little bit of mental kung fu has not been practiced, then there is no need to talk about swords.

Then there was silence in the hall, the woman in the white dress, Ximen Fox, Jing Jian, Duan Yu, Zhang Jingtao, these five people all stood in front of the desk, silent.

But there is a sharp momentum on the body.
