Just when Shang Wen was preparing to use financial means to solve the issue of compensation between Yan and Zhao. Qin's economy was in full swing to absorb the gold reserves of the six countries.

The industrial system of the Qin State was initially established, first of all, heavy industry based on military production, and iron ore smelting in the Guyang Iron Works in the north. The abundance of open-pit coal in the area, as well as the nearby iron mines, now Baiyun Obo, provided the Qin State with an abundant supply of iron resources. This also paved the Qin state to quickly establish iron as the primary metal position to replace bronze.

In terms of iron smelting technology, the Qin State first used coal coke iron smelting technology, which no country can know. And the Six Kingdoms didn't understand why Qin's iron-smelting technology had advanced so rapidly overnight.

The extensive use of iron enabled the Qin state to rapidly develop various affairs. For example, Guyang Iron Works uses a large hot rolling mill to produce not only the necessary iron ingots or various blank tubes for China. At the same time, it also produces some building materials independently. The advent of cement brought a lot of changes to the architecture of the Qin State.

Wealthy families began to use cement mixed iron bars on a large scale to build a large number of sturdy buildings, and two- or three-story buildings began to be used in the new towns selected by the Qin state. At the same time, it began to be used in some small towns of newly established states.

Cement plants began to be built in response to huge demand. Many factory owners are involved. For example, Yingyu intervened in Guyang Iron Works by way of loans, and finally re-injected capital to become a shareholder. Took control of the largest iron factory in the Qin State. At the same time, a large-scale cement plant was built around the iron plant. Because when processing iron, some by-products. Or it can be produced by heating. As a result, Guyang also became the largest cement plant in Qin.

Weapons, cement, iron bars and other building materials produced by heavy industry entered the Qin State at the same time, but also entered the markets of other countries. And these are all the leading products of the Qin State.

Taking Zhao as an example, the emergence of new building materials made King Zhao begin to reconsider the construction of the palace. At the same time, some of the clan's children began to use this sturdy material to build defenses. Because of the upgrade of weapons, the original rammed wall could not withstand the attack of the cannons.

While smuggling weapons to make a fortune, the Qin State was also importing sturdy building materials. It's contradictory, but it's not contradictory at all for the Qin State, because they're making money. Who has a contradiction with making money.

Due to the high demand in the country, these building materials cannot be produced in a short period of time. Although some factories have been built, they will not be able to start production until after the beginning of spring at the earliest. Therefore, the price of cement is extremely high. One gold is given to three stones. Iron bars have standards due to the production of the Qin State. Therefore, most of them are still imported from Qin. With the building materials, it is also necessary to ask the engineers of the Qin State to build it, because the proportion of concrete is only known to the engineers of the Qin State. This is also a large amount of expenditure, after the retirement of a large number of engineering troops in the Qin State, they set up their own training courses, or opened construction firms, contracting large and small construction projects at home and abroad. They made a fortune from it.

At the same time as these things are imported, they are also absorbing a large amount of gold from various countries. Because the exchange of paper money in the Qin State has a certain link to gold. The listing of gold futures directly gave an equivalent exchange between paper money and gold. Gold is depreciating. Because the gold reserves of the Qin State have reached an astonishing number. The underground palace of the Qin Palace's palace could no longer accumulate a large amount of gold. The Qin state was using new building materials to build new underground palaces to store the gold. But how much gold there is, no one knows.

Not only in heavy industry, but also in the light industry of the Qin State, which greatly absorbed the gold of the Six Kingdoms. The Qin State controlled the fashion trends of the Six Kingdoms, for example, ladies began to use leather bags. Perms, wearing leather clothes, high heels, etc. These things have become very popular on the streets of Xianyang, Qin State. Moreover, with Xianyang as the center, it began to radiate the entire Guanzhong and the newly established state on a large scale, because the people had a rich family foundation. Truckloads of wheat began to be hauled into futures trading centers or into mills to be processed into flour. Then enter Xianyang and board the train from Xianyang. Or it can be transported to various countries by horse-drawn carriage. The Six Nations began to phase out corn in large numbers, and flour is replacing corn as the main food dish. And all this in exchange for a lot of money for the farmer, with money, they not only paid off the bank loan, but at the same time, they also began to have new pursuits, and women began to dress up. Men are starting to pay attention to what they wear. Because they didn't have to work in the fields in dirty clothes, everything was done by slaves.

This in turn absorbed a lot of gold for the Qin State, because it was impossible for people to leave food, not only that, but the purchasing officials of the royal family gathered in Xianyang, and they frantically purchased all the strange goods, and the demand for perfume has far surpassed other commodities, becoming the main commodity of the royal harem, and under this stimulus, a large number of perfumes of various flavors are frequently launched. Then there's the costumes, the heels. In particular, the state of Chu purchased a huge amount of high heels. Because, high heels can make the women in the palace walk more gracefully. This variety is very attractive. Being able to have a pair of high heels became a symbol of the status of women in the palace of the king of Chu. Even the maids desperately needed a pair of high heels.

And not just high heels. Mirror. Especially the big glass mirrors. It became an essential material for the decoration of the royal family. The state of Chu has a very big demand for this.

There are only two countries that are able to decorate such large glass mirrors. One is the Qin State, which is the largest producer, so the decoration of glass mirrors is a smooth thing. But the state of Chu became the second.

A large number of glass mirrors that can clearly reflect the shadow of a person were imported by the Chu State, and a large number of glass mirrors were placed in the palace in the Chu King Palace of Shouchun of the Chu State. Not only inside the palace. In the harem, all the concubines who were very favored by the king of Chu were installed with a large number of glass mirrors. Moreover, the glass mirror of a concubine has somewhat become a symbol of this woman's status in the harem. Even those maids of the palace of the king of Chu will be able to have a small glass mirror as a kind of great vanity to show off.

Unlike the Chu State, the other countries were very stingy. Zhao Guo only has a few pieces in the main hall, and the small pieces of glass mirrors have become the personal objects of the favored concubine. Several other countries are no better off there, mainly because of the growing lack of gold in the country. Even those knife coins have risen to a high level. And what caused all this was Qin State's very powerful gold absorption**. The Qin state occupies a central position in all trade. This was the beginning of the trade of the Qin State. Laid the position of hegemon.
