The original purpose was to create paper for rubbing paper, thus developing 丨Tiangong glue paper丨As soon as Puti was born, it caused a sensation in the circle of the Great Wilderness World: Aristocrats and Clans.

In addition, there are various types of papers such as Tiangong straw paper, Tiangong bamboo paper, Tiangong rice paper, Tiangong Dan paper, Tiangong oil paper, Tiangong oil paper, etc., which were also gradually studied by craftsmen from the paper mill under Gu Yi's guidance.

Gu Yi even urged paper mills to study very special "money printing paper". As for the purpose, it is naturally not necessary to explain.

Ten pieces of Tiangong paper, a size of a square meter, are sold for only one large gold. Although the price is not cheap, it cannot be considered expensive. The most important thing is that as long as you pay for this kind of paper, some of them are sold in Tiangong Wenbao Shuxuan. Unlike Tianheng silk paper, due to the output, you may not be able to buy it if you have money.

Think about it, in the ghost place where "a book is worth ten thousand gold", such a terrifying writing vehicle suddenly appeared, which made those gentry members not crazy. Almost all merchants, no matter what business they originally did, after discovering Tiangong Paper, they wanted to take out all the money they had on and exchange it for paper and transport it back.

In this way, the Tiangong Paper Factory, which was originally built just to make paper, suddenly transformed into Tiangong Money Factory, and was there paper? It was all piles of big gold cakes.

There are many other products like this, such as soap, soap, various cloth products, Mingguang jade, green stone jade, and various fine wines... Most merchants have spent all the money they brought before they can go out on the Golden Avenue, and they have spent all the money they bring. It is really "produced by Tiangong, it must be a fine product". If you don't buy it, you will feel like you have lost it.

This led to a saying among merchants that began to spread, that is, "If you don't have the work, you won't know how much money you have", no matter how much you bring, it is not enough.

What made Gu Yi most proud is that the commercial city does not collect currencies other than industrial RMB. If merchants want to consume in the commercial city, they must first exchange the large amount of gold they bring in the currency exchange to industrial RMB.

When the exchange rate of the Industrial RMB to the Dajin Cake is l:I, it is not exchanged according to the Dajin l:l obtained by merchants, but it must be melted on the spot and extracted "pure copper", which is the so-called "red copper" or "pure copper", and recast into standard ingots, before it can be exchanged with the Industrial RMB.

Although it seems like a waste of time, with the casting process of Dahuang, it is impossible to accurately ensure the weight of each large gold.

According to the standard of one big gold cake, some big gold is less than UU0 grams, some big gold is as high as 0 grams, and even the lowest one is only 500 grams, and the highest one can reach 700 grams. The gap between them is too big.

Moreover, the big gold cakes brought by merchants from all over the world are not made of a unified material. Due to the different productions in different places, brass, bronze, white copper, and copper are different, but the purchasing power is the same.

The impurities or alloy components contained in various copper are also different, such as "tin, zinc, nickel", and some also contain "lead" and "aluminum". The melting points of these metals are different:

Tin 23℃, lead 8℃, zinc 0℃, aluminum UU0℃, copper 1083℃, nickel 1453℃ (rounded by numbers after decimal points).

Therefore, after a simple melting point separation, acid-base replacement heating and condensation process, relatively pure metals can be obtained (the existing technology cannot achieve absolute purification), brass contains about 40% zinc, bronze contains about 35% tin, white copper contains about 30% nickel, and relatively pure copper contains about 10% alloy "impurities" like silver.

These "impurities" that account for about 30% of the large gold component are of course directly "discarded". Only about 70% of the copper remaining can be cast into a standard ingot of 630 grams per month, and then exchanged with the currency exchange 丨 l:l to RMB, which directly shrank by 30%

In order to refine the big gold, Gu Yi also specially asked the famous craftsmen to design a set of special furnaces of different specifications and sizes to accurately control the temperature so as to separate different metal "impurities" at specific temperatures.

Merchants from all over the world were surprised. They had used the big gold cakes for their whole life, but they never knew that the big gold cakes contained so many impurities. However, if they felt that it was not cost-effective to lose money, the currency exchange would still give out the full amount of the big gold rolls before smelting the big gold, or Yu Qian would return it to you the same amount of big gold cakes.

However, using 丨Tianheng Golden Roll丨Purchase of Tiangong products is twice as expensive as using RMB to buy. It is still cost-effective to exchange RMB. As for unrefined big gold cakes, 丨Commercial City丨It is absolutely not charged...

Why not accept it?

Others丨The staff of the currency exchange will point out with contempt and said, "Can you use these poor money as money? We丨Commercial City丨is used to lay the floor"

In addition to the gorgeous face-covering retreat, you can choose to go home directly, or sell the goods you bring to the Commercial City and receive the Tiangong Gold Roll for payment, which is a delicate metal check board as the size of a palm.

丨Commercial City丨Only use 丨Tiangong Gold Rolls丨Perform payment, not pay gold cakes and 丨Tianheng Gold Rolls丨, but 丨Tiangong Gold Rolls can only be used in 丨Commercial City丨, just like shopping cards issued in supermarkets. Although you have a penny of your money, it is limited to the amount of money you can only spend in 丨Commercial City丨.

It means that after merchants dragged goods from all over the country, they would not even think of taking away a penny from the commercial city. All they could take away was the various Tiangong products in the commercial city, which belong to "compulsory consumption".

Whether it is the RMB or the Jinshu, it is useless if you leave the Commercial City, so it would be fine if you spend all the RMB you exchanged for at once. If you don’t spend it, you have to do it again next time, otherwise wouldn’t that money be wasted?

But the remaining little money will definitely not be enough to spend next time, so you have to exchange it with big gold. If you exchange it and it cannot be spent, you have to come again next time... It has formed a vicious cycle

Well, take a step back and say, even if you calculate accurately, you just spent all the RMB in your work and RMB to kill you and don’t come next time? As a merchant, are you willing to leave the Tiangong product supply in the commercial city?

The answer is yes, isn't it?

Therefore, although merchants complain about the various systems of commercial cities, they have to act according to the rules of commercial cities. Who said that the various Tiangong products in commercial cities are all scarce resources and belong to the seller's market?

And all of this is exactly what Gu Yi wanted to achieve through the Commercial City: to break the original laws of the Great Wilderness World and establish the unique rules of Tiangong Group, or in other words, he wanted to transform from a "rule obedient" to a "rule maker".

While observing the various changes in the commercial city, Gu Yi smiled with satisfaction. As it seems, his plan is still very successful. Although the commercial city, which is located in a corner, cannot use his own rules to influence the entire world of the Great Wilderness, at least, he already has a tool to compete to change the laws of the Great Wilderness.

"Don't the commercial city not allow people with disheveled clothes to enter? How did these dirty mountain barbarians get in? Where is your manager? Why don't you call the urban management and blow them out quickly?"

Gu Yi, who was so beautiful, suddenly heard someone arrogantly behind him and suddenly heard words such as "manager", "urban management", etc., and looked back in surprise, but a merchant was pointing fingers and gestured at their group.

Gu Yi was stunned for a moment before he remembered that he appointed the manager of the shop as "manager", and called the Gothic Xuanbing who managed the commercial city and public security "urban management", but it was also the product of his evil taste.

But how could someone teach him a lesson?

Gu Yi looked down at himself, then looked back at Zi Yu with a helpless look on his face, and understood that he had violated his own regulations that "those who are not dressed in a mess" were not allowed to enter. But even if he violated the law by "knowing the law", when will it be the turn of this foreign businessman to teach him a lesson?

He looked at the fat guy with big ears in surprise, wearing a luxurious brocade robe, and a group of guards were following him, but he didn't look like a big man. He seemed to be either the accountant of the business or the tycoon of the clan.

Customers are God, and they always come to give him money. Gu Yi felt that he needed to be more kind, so he smiled without caring about him.

The rich man saw Gu Yi laughing at him, and thought that his power just now had shocked these rusty barbarians. In addition, the eyes of the customers in the store, he proudly said to the shopping guide maid beside him: "Why donkey goods be beaten out quickly and don't be afraid that Tai Bo will support you, just teach them a lesson"

The graceful shopping guide maid on the side was full of embarrassment, but she wanted to roll her eyes at the leopard. They had met Tiangong in training class and had long recognized Tiangong who had "limited visits". If Mr. Ziyu, who was beside Tiangong, had secretly waved to her when he came in, he would have come to salute her.

And this rich man actually asked her to drive out the tutor. Isn’t this cheating?
