The situation on Elysium Island was a little more complicated than Xu Xian had imagined.

The language spoken here is the Central Plains, but few people speak it on the streets, and even in the free exchange trade, communication is made or not.

Each takes out its own goods, if both parties feel that the exchange is appropriate, then exchange, if they feel that it is not suitable, the sale cannot be done, both parties can add conditions, but it is also carried out within a reasonable degree.

Here, gold and silver can also be used, especially those gambling houses and green houses, which only recognize gold and silver, and almost everyone on this island has a lot of money, so silver is not used as the main trading tool here, but gold.

“…… Brother-in-law, I've also seen the situation on the island, what are we going to do next? ”

After Xiaoqing followed Xu Xian for a while, she couldn't help but ask impatiently.

Xu Xian said: "The most supple goods on this island are actually copper products, and whoever has higher quality copper products can exchange them for some rare treasures in the ocean, and they can exchange for more gold." ”

"Brother-in-law, do you want me to go find some copper products and come back?" Xiao Qing asked with wide eyes.

"There is no need for copper products, no matter what kind of copper products you go to find and come back, there will be no big breakthrough in the things you get, there must be better quality things, especially the things that the sea people need, in order to exchange for greater benefits." Xu Xian looked at a few merchants on the side of the road who had Dongzhu and coral, and even the night pearl under the sea, many people wanted to exchange copper products with these people, but these people refused to exchange, and as for gold and silver, they were not in the eyes of these people.

Xiaoqing asked, "Where can my brother-in-law go to find something better?" ”

Xu Xian sighed: "If you want to say that something better than a bronze mirror, it is naturally glass products, but the glass products of this era are too primitive, and there is no ...... on this island that sells this thing."

"Brother-in-law, what is glass?" Xiaoqing asked with a wink.

"How to say it, it's actually a chemically manufactured thing, mainly using quartz sand and soda ash...... That is, soda is used for calcination, but some other processes are added, and it is not very easy to turn it into a piece of flat glass, which needs to be stretched or vertically led at high temperatures...... It is almost impossible to do it under today's conditions, but it is possible to make some glass beads. Xu Xian imagined.

Xiaoqing looked eager to try, and said, "Brother-in-law, let's try it later?" ”

"Forget it, we don't have much time, this time we went to the island, our main purpose is to observe the situation here, so that we can do business in the future." Xu Xian said, "I didn't bring any money with me this time, it seems that I can only go to the wilderness to rest first, and I don't know how to leave this island and return to Yanshan County......"

Xiaoqing said: "Brother-in-law, since we can't go back for the time being, let's go outside this small town to find a place to rest first." ”

"Hmm." Xu Xian nodded, and went out of the town on the island with Xiaoqing and the others.

As soon as he came out, Xu Xian felt that he was spinning again, and then Xu Xian passed out in a coma, and in the moment before the coma, Xu Xian was thinking in his heart, next time it was best not to come out with Xiaoqing, otherwise she would always mess around.

After Xu Xian fell into a coma, Xiaoqing seemed to be very enthusiastic, and first put Xu Xian in a very warm thatched pile, she said to herself: "What kind of glass does my brother-in-law want to make, then I will help him, so that my brother-in-law can make a lot of money once he comes out, I will make it according to the method he said!" ”

After Xu Xian provided some original technical information, she went to find the quartz sand and soda ash that Xu Xian said, and then began to make glass.

……

……

Xu Xian woke up from sleep, the sky was already dark, he suddenly jumped up from the grass, and just as he felt that something was wrong, he quickly stood up and prepared to leave.

But seeing that Xiaoqing had already appeared in front of Xu Xian with a piece of flat glass.

"Brother-in-law, is this what you're looking for?" Xiaoqing asked with a smile.

When Xu Xian saw the glass, he simply didn't know what to say.

In his opinion, this is simply crazy, the scientific and technological stuff can be completed in one night with the blessing of spells, if this thing is studied on land, even if there is a ready-made technology, it may take several years to develop.

"Uh...... How did you get there? Xu Xian asked.

Xiaoqing said: "I found a lot of furnaces in the small village, and I went to find some materials, so I tried it according to the method that my brother-in-law said, and it was done, and if my brother-in-law needed it, I would go and get some for my brother-in-law." ”

Xu Xian's face was very embarrassed, this kind of lame reason changed to the wise him, and he didn't believe it when he was killed.

But even if he knows Xiaoqing's origin, and he also knows what Xiaoqing relied on to make the glass, even if this reason is really full of loopholes, he still has to pretend that everything is reasonable and let himself accept it in his heart.

"I didn't expect you to be so capable." Xu Xian smiled, "With this thing, it's not enough, you need to use a small chemical reaction to plate the silver on the glass." ”

Xiaoqing asked curiously, "How do you plate the silver?" ”

"Silver Mirror Reaction...... It's a bit complicated to say, to make some raw materials, the most important thing is to dissolve the silver in a nitric acid solvent, if there is electricity......" Xu Xian said, he could only describe as much as possible, and Xiaoqing was also listening carefully.

"Brother-in-law, you wait a minute, I'll see if I can find the materials and come back......" Xiaoqing slipped away again after listening to Xu Xian's description.

When Xiaoqing appeared in front of Xu Xian again, there were already a few more silver-plated glass mirrors in his hand, Xu Xian took it in his hand, looked inside, and clearly showed his image inside.

Xu Xian smiled: "This is it." ”

"What's the use of this...... Ah, here's ...... Why is there still a me? Xiaoqing was busy showing Xu Xian her achievements before, and she didn't look at the glass mirror carefully, and after she looked at it, her eyes couldn't be pulled out.

"This thing, in fact, is to replace the bronze mirror, isn't this effect much better than the bronze mirror? If you take this thing to the market on the island and exchange it, you should be able to exchange it for some treasures, right? Xu Xian said with a smile.

Xiaoqing had a cheerful smile on her face, and her eyes narrowed into two crescents, looking very playful.

"I didn't expect this thing to be so good, brother-in-law...... What are we waiting for, let's go and see what we can get, and if it's feasible, we'll come back and continue to make some more, and we'll be fully loaded. Xiaoqing Mei Zizizi.

Xu Xian nodded and said, "Then let's go to the market to have a look, it's best to get something valuable but not heavy, otherwise our small boat really can't be taken away." ”
