The bazaar is actually not far from Huaiyuan Town, and when the escorted sergeant arrived at the place, Wang Xiang found that it was more lively than he imagined, the bazaar was very large, and there were many people, and there were already many people who had set up stalls in the bazaar, on which there were all kinds of goods, and those merchants from the Western Regions who were dressed differently were obviously from different countries.

Everyone seemed to be accustomed to the sergeants escorting the people and merchants over, and Wang Xiang's arrival did not cause much commotion.

When they arrived at the bazaar, the people and merchants who had come with the sergeants separated to find a suitable exchange partner, and then came back when the time came to return to Huaiyuan Town.

The captain of the team who led the team to the market today is called Wang Xi, a young man, Wang Xiang said to him and wandered around with the iron egg, Wang Xi wanted to arrange two sergeants to protect Wang Xiang but he refused, now others don't know who he is, if you get two sergeants to follow behind, it will attract attention, and there is an iron egg by his side, and he has a warehouse such a life-saving weapon basically will not have any problems.

Wang Xi also felt that it made sense when he heard it, so he didn't force it, they also needed to purchase some things for the army when they came out this time, so it was not good to delay much, and asked Wang Xiang to take other sergeants to exchange goods if he had something to do with him.

There are all kinds of things in the bazaar, there are animal skins, herbs and ores, and even some unknown animal bones, which dazzle Wang Xiang, while the people and merchants of the Tang Dynasty brought mostly grains and other grains, as well as a small amount of porcelain and tea and other valuables.

The porcelain and tea of the Tang Dynasty are very popular here, and they are often snatched up as soon as they are taken out, and most of them are exchanged for fine animal skins and cherished medicinal materials, and many of those unknown animal bones are also commonly used medicinal materials.

Wang Xiang is just wandering around, and he doesn't have any special goals, there are many things he hasn't seen here, and it's quite interesting to ask this and that.

Suddenly, something in front of a merchant from the Western Regions caught his attention, it was an inconspicuous black stone.

"What is this?"

The stall Wang Xiang pointed to was a small man with pigtails in the Western Regions, and Wang Xiang couldn't tell which country it was from the Western Regions.

Kasan is a merchant in Yanqi country, this time brought a lot of things to trade, seeing that Wang Xiang asked about the black stone he inadvertently dug up, he was suddenly a little interested, this thing was dug by him, and he didn't know what it was for, but he felt that the black stone was more peculiar, so he brought it over and put it on the stall to try, but after a few days, although a few people asked, but no one was willing to exchange things for this useless black stone, he planned to throw this stone away.

"It's a black stone."

Hearing Kassan's introduction, Wang Xiang was stunned for a moment, what kind of introduction is this......

Actually, Kasan didn't know how to introduce it, because he didn't know what the black stone was for.

"Why don't you take a look at the other goods, I have the best quality fox skins here, as well as all kinds of fine medicinal materials."

Wang Xiang was not interested in animal skins or anything like that, but picked up the black stone and looked at it carefully.

It's really coal, a natural coal mine!

"Where did you find this stone?" Although Wang Xiang was a little excited in his heart, he still remained calm on his face.

Kasan didn't know why Wang Xiang was interested in this black stone, and replied casually: "This is dug in a wasteland outside our Yanqi, and it is strange to say, our Yanqi is full of lush grasslands, but there are a few pieces of land that are barren, and not a single grass grows. ”

It's no wonder that the underground is all coal mines, Wang Xiang laughed in his heart.

"Are there a lot of black stones like that out there?"

Kasan thought for a moment and nodded, "It seems that there are quite a few." ”

Wang Xiang showed a smile on his face and said, "What goods do you need?" ”

Kasan was stunned for a moment, he didn't expect that Wang Xiang really wanted to exchange this black stone, and asked what goods he needed, and he didn't know how to make a price for a while, after all, he was already planning to throw this stone away.

After thinking for a while, Kasan asked tentatively, "Are you really going to want this stone?" ”

Wang Xiang nodded and said, "Of course, and I don't want this piece, but a lot." ”

"A lot?" Kasan was even more confused: "How much are you going to want?" ”

"As much as you want."

"Ahh Kasan was really pleasantly surprised, there were many such black stones in Yanqi, he never thought that anyone would really want this kind of black stone, and said how many there were, and the other party spoke very seriously and didn't look like he was joking.

Seeing that Kasan was stunned, Wang Xiang simply took out a glass bead the size of a fingernail and said, "How about exchanging a bead for a cart of black stones?" ”

"Glass beads!"

"That's right, Liulizhu." Wang Xiang saw Kassan's eyes shining and smiled, this thing is actually just a glass bead fired by the Gewu Academy, Wang Xiang let people burn a lot of such beads to bring on his body, he always feels that it is more convenient than carrying silver, and copper coins can not be compared, in the eyes of others, this is a glass bead of good quality, a small thumb nail size bead is worth at least dozens of times, that is, tens of thousands of copper coins, Wang Xiang really can't imagine who will be okay with tens of thousands of copper coins on his body......

"Are you really willing to trade a glass bead for a cart of black stones?" Kasan felt something unreal.

"Of course, I can pay you a deposit for a car upfront."

Kasang carefully took the beads handed by Wang Xiang and put them in the palm of his hand to observe, the beads are crystal clear, the most rare thing is that it is round, it is really very round, he has seen a lot of glass beads, but he has never seen such a round.

It must not be easy for someone to take out such a glass bead casually, and Yanqi has always been obedient to Datang, although Kasang wants to do this deal, but he is also afraid that Wang Xiang will regret it in the future and bring trouble to himself, so he opened his mouth and persuaded: "Friend of Datang, I Kasang will never deceive friends, this kind of black stone has a lot in our Yanqi, but it is useless at all, otherwise you should take a look at my other goods here." He really couldn't bear this glass bead, and hoped that Wang Xiang would be able to take a fancy to other goods.

Wang Xiang didn't expect the little merchant named Kasan to be so honest, he laughed and said: "Kasan, you have the best qualities of a businessman, I am willing to make you a friend, but I really want to buy this black stone, so you don't have to worry that I will regret it, as long as you can bring me a cart of such stones, I will pay you a glass bead, and when the time comes, you can bring the stones just by telling those sergeants." ”

After listening to Wang Xiang's words, Kasang had no doubts, and patted his chest happily: "Don't worry, I'll go back to Yanqi tomorrow, and I'll definitely bring you a few carts of black stones, but it may take a little time." ”

Wang Xiang reminded: "You can hire someone to help dig the stones, and I will pay them." ”

Kasang hurriedly waved his hand and said, "No, no, I'll just pay the salary." For him, this transaction is simply unprofitable, how can he make Wang Xiang pay his wages.

Kassan, who originally planned to go back to Yanqi tomorrow, thought about it and decided to leave to return to Yanqi immediately, a cart of stones can be exchanged for a high-quality glass bead, where does he still have the heart to set up a stall, and it is the right thing to go back to dig stones as soon as possible.

For Wang Xiang, there is no more cost-effective deal than a glass bead casually fired by the Gewuyuan in exchange for a car of coal mines, and what he has to think about now is how to transport these coal mines back to Chang'an.
