When Rough reappeared, he still controlled an ordinary person, as a prosthetic body for him to walk the earth, and communicated with Pipixia, and the two met with a hypocrisy.

"Ah, dear friend, we meet again."

"Yes, yes, I haven't seen you for a day, like every three autumns, I miss it very much."

“……”

After a greeting without nutrition, I still couldn't hold back and cut to the point: "Dear Xia, as agreed last time, I came to establish a formal business channel with you. You've got to come up with something good, or you'll be sorry for me. ”

This made Pipicia a little surprised, he didn't expect that Rough Te was actually more breathless than him, and the need for business was more urgent, although he didn't know the internal reason, but this was obviously a good thing for him: "Dear Rough Rought, I believe that the prospects for our cooperation must be very broad, and this is where our common interests lie, isn't it?" ”

"I hope my investment is not wrong," said this, the air in the hand of the bumpy hand was distorted, and a copper disk with complex patterns had appeared, as if engraved with a magic array: "This is an alien astrolabe, two by two, with a wonderful substance built, this material is a twin structure, disassembled and placed in a different alien astrolabe, activating any half, it can be connected with the other half, forming a space-time channel, so that the two sides can transport goods through this channel, which greatly saves the energy required to cross the world barrier." ”

As he spoke, he taught Pippia how to use it in detail.

Pipixia watched a small commodity disappear under the absorption of the alien astrolabe, and then appeared on the other half of the alien astrolabe, and couldn't help but feel very interesting, and at the same time, his heart moved, and a very important news was revealed in the words of the bumpy.

The cost of this Void Merchant's crossing the world barrier seems to be very high, when it comes to the need to consume energy, the heartache that unconsciously flows is not fake, in comparison, the cost of crossing the world by himself seems to be much lighter, and the hand that crosses the world only consumes some physical strength, and the gap seems to be a bit big.

But he was also cunning, and quietly praised: "It's so convenient, I feel that after using this kind of prop, the energy consumption has become much smaller." ”

There was a hint of pride in his tone: "Of course, the alien astrolabe is the secret of my success, which greatly reduces the cost of space-time trade, by the way, Xia, I also want to warn you here, the alien astrolabe is engraved with a self-destruct brand, don't think about cracking it, what bad consequences will happen, you have to bear it." ”

This time, Pippia confirmed that it was indeed not as easy as it was for him to travel through time and space, and the cost was much greater: "Don't worry, I won't spy on my partner's secrets." ”

Unaware that he had inadvertently leaked some information, he was overjoyed: "That's the best, by the way, the Alien Disk also has an instant communication function, as long as it is in this way, half of the energy particles in it can transmit information to the other side......"

After the introduction of the functions of the alien astrolabe, Pipixia nodded with satisfaction, many of the functions of this thing are similar to mobile phones and computers, but there is an additional physical transmission function, which is very advanced, and then smiled slyly, and said sincerely: "Speaking of which, it is not easy for us to meet every time, it is rare that you are here again today, but I don't know if you have brought any goods?" If we can trade, we can trade it, so as not to go home empty-handed and consume an extra amount of energy, which is a crime that increases the cost! ”

"This is indeed good advice, and if you have goods of equivalent value, of course I am more than happy to trade," said Rough wary, "but ...... If it were these low-value goods, I wouldn't agree to exchange them. ”

He looked around the general merchandise in the grocery store and felt a sense of concern.

"Of course, the equivalent exchange, I know, but if you don't look at the value of the goods you bring first, I don't have any points in my heart, right?" Pipicia has a point.

Rough hesitated for a moment, but finally nodded: "I'll send the list of goods to your alien disk." ”

After some manipulation, Pipicia activated the alien astrolabe in his hand according to the usage method taught by Rought before, and an image like a three-dimensional projection suddenly appeared in the air, which was a list of goods that Rought carried this time, illustrated and textual, and there were things like demonstration videos, even if Pipicia didn't understand the words of the Rought family, it would not affect the understanding of the purpose of these goods.

In general, there are more than 1,000 types of goods in Bumpy, mainly minerals, all kinds of minerals that have never been seen before, and minerals with special functions like Xijin, this part accounts for half of all types of goods.

Seventy percent of the remaining half are plants with strange effects, such as gold-eating flowers, which feed on different metals, and after some digestion and absorption, they grow out of alloys made of devoured metals.

In the end, the rest are artificial products, all weapons, armor, jewelry, etc., but these finished products seem to be biased towards magical items, such as combat boots that increase speed, sharp greatswords with lightning power, necklaces that can activate energy barriers in case of danger, and so on.

It seems that the main business of Rough is more raw materials and magical products.

Looking at the price tag of these goods, most of them are a standard unit of stardust in exchange for a group of corresponding goods, a few are higher, and the highest price is worth five stardust, which makes Pipixia's heart move.

According to the information he inherited from the Void Spirits, the flow of time and space is too vast and complex to have a unified currency, and the most common general equivalent is stardust.

The so-called stardust is a crystallization of special particles, containing extremely powerful energy, the size of a standard unit of stardust is similar to a grain of rice, but if the energy inside is needed for the energy of the entire earth in modern society, it is estimated that it can be maintained for hundreds of years.

This kind of crystallization also has an extremely crazy characteristic, the creation attribute, which can become any existence according to the user's mind, whether it is inorganic or organic, inanimate or living object, many powerful beings of the flow of time and space rely on stardust, and can even create worlds, which is also the fundamental reason why stardust is hard enough as currency.

However, although Pipicia lacks the current business information of the flow of time and space and does not understand the current market, he also knows that no matter how shabby the existence of a powerful flow of time and space is, he will not care about stardust and stardust, but most of the goods are that a stardust can buy a bunch of raw materials, which has exposed his background.

In other words, Rough will definitely not be a wealthy merchant among the Void Merchants, and it is very likely that he will be a footman similar to the Singles Gang, so that his distress about the cost of traveling through the world is explained.

Probably he thought he was a country void citizen who was even more ignorant than he was.

Well, but that's right, my knowledge of the flow of time and space comes entirely from a vanishing void geist.

With this consideration, Pipicia already knew how to deal with Rough Weather: "Sure enough, it's all good things, but, Rough Weather, stardust is too precious, I really don't have it, and it's not easy for you to come here, and you have also built a time and space trade road with me, if you don't change something, you will go back, I'm afraid it will also be a lossy transaction, so let's take credit, okay?" ”
