Chapter 890 Copper

After Wu Changqing consumed this wave, he looked at the system data.

Host: Wu Changqing.

The current territorial area is 12.4 million square kilometers, the total resource points are 372 million, and the remaining 328.5 million.

The current population of the jurisdiction is 220.4 million, with a total of 220.4 million technology points and 156.32 million remaining.

It seems that there are still many resource points and technology points, but the further you go, the less expensive it is.

Like this time, just for the needs of the steel industry, he spent 20 million resource points and 5 million technology points.

This kind of consumption will disappear after a dozen or twenty times.

The system also reminded that it will be updated in the future. According to Wu Changqing's experience in playing games, the update is to stimulate players' consumption, and there will definitely be some expensive new gadgets.

Therefore, Wu Changqing can't use up all these resource points and technology points, and has to keep some of them just in case.

In case after the update, there are materials in the store that can achieve superconductivity at room temperature, or controllable nuclear fusion materials and technology, or there is a magic medicine that can keep a man in his 70s and keep his majesty, there are no resources to buy it Aren't you going to cry to death?

No matter how well Dahua develops, it is not as good as his glory, or his personal longevity is important, and he is not a real saint.

The land area on the earth is limited, and Wu Changqing is not sure whether the system will recognize such a thing as planting a flag on the moon and announcing that the moon is the territory of Dahua.

Up to now, the whole world is under Wu Changqing's control.

The only thing that cannot be controlled and is still full of mystery is this broken system.

Facing this unknown gadget, Wu Changqing was very cautious, neither used it excessively nor completely relied on it.

He didn't know whether it was right to do so, and he would only know later.

The emergence of stainless steel is an evolution of the steel industry.

In the past, it solved the problem of creating something from nothing, but now it solves the problem of building something from nothing.

With various stainless steels, the performance of the machine can be greatly improved.

At the same time, some machines that could not be manufactured before can also be manufactured now.

For example, the high-speed engine, the engine made of ordinary steel in the past, cannot be too fast, and the parts will be damaged quickly if it is too fast.

A machine that cannot be operated continuously is useless even if it is built.

With the use of special stainless steel, the service life of the components can be greatly improved, and the engine can be turned faster.

The improvement of engine performance has a huge impetus to the entire industry.

This is still the premise of building an airplane. If the speed is not fast enough, there is no way to go to the sky.

Now, as long as the engine continues to be improved, it is theoretically possible to manufacture aircraft.

Both hot air balloons and hydrogen balloons have great flaws, that is, they are used for military purposes to achieve miraculous effects, but they do not have much effect at other times.

With Wu Changqing's reminder, some people are already studying the problem of flying into the sky.

With special steel, projects that could not be done before can now be put on the agenda, such as the Nanjing Yangtze River Bridge.

This is an important project to connect the north-south railway, and it has been proposed many times.

It's just that people from the former Ministry of Science and Technology said that the current strength and toughness of steel are simply not enough. Either the bridge piers are built very low and densely, so that the intervals are very close, otherwise the steel will collapse due to insufficient strength and toughness.

The piers are built too low, and the spacing is too small, which will affect the passage of ships, which is not cost-effective.

Therefore, this project has been dragged down.

But now, as long as high-strength low-alloy steel is used, the span of the bridge can be increased, and ships under 5,000 tons can pass through.

Although there are still many difficulties, in theory, it has the ability to build a bridge across the Yangtze River in Nanjing.

Connecting the north-south railways and roads will greatly save the cost of north-south transportation.

Due to the obstruction of the Yangtze River, the current north-south transportation has to be transshipped several times in the middle, which is very troublesome.

After the coal from the north is transported to the north bank of Nanjing by train, it must be transported to the south bank by ship.

Loading and unloading is time-consuming and labor-intensive.

This situation is not limited to Nanjing. Wuhan, Zhenjiang, Wuhu, and all the cities along the Yangtze River all have the need to build bridges across the river.

The same is true of other places with big rivers.

Dahua's infrastructure project has just begun.

Steel is the most used metal in Dahua, followed by copper and aluminum.

Silver is the best conductive metal, but silver is a high-value currency, and Dahua has no luxury to use silver to make wires.

If this is done, there will be countless people cutting wires and selling them at night.

Those power lines in the wilderness will certainly not be spared.

When the income is high to a certain extent, it is difficult for the law to maintain its deterrent effect.

Therefore, Dahua's current cables are all made of copper, and the crime of stealing wires is very serious. Minimum ten years to start, causing heavy losses and immediate death penalty.

Only in this way can those thieves give up the idea of ​​stealing.

In addition to making cables, copper is also widely used in other ways. After the flintlock was eliminated, Dahua now makes bullets and some shells are all made of copper.

Machine parts such as door valves, moulds, sliding bearings, etc. also need to use copper.

In fact, the Central Plains is quite short of copper, and now the transportation of copper

The scope of application is getting wider and wider, and the demand is increasing, and the supply has been in short supply.

For this reason, Wu Changqing also issued a decree, that is, when collecting taxes, no copper coins will be collected, only silver coins and banknotes will be accepted.

The purpose of this is to completely replace copper coins with paper money, so that the copper can be used in industry and other aspects.

It is too wasteful and unnecessary to use it as currency circulation.

And it's inconvenient. Now that the price of goods has risen so much, a penny has become worthless.

Buying things with copper coins is exhausting.

In order to avoid causing too much turmoil, Wu Changqing did not prohibit the circulation of copper coins, nor did he force people to exchange copper coins for banknotes.

In that case, it is easy to cause panic and hoarding.

Moreover, paper currency has not yet become popular in remote areas, and the main currency is still copper coins.

Wanting to completely replace copper coins with banknotes at one go is a bit too big a step, and it is easy to tear the eggs.

Anyway, Dahua is not particularly short of copper in the industry for the time being, but it may be short in the future.

Therefore, there is no need to rush for a while, you can slowly replace copper coins with paper money.

As long as people find that using paper money has not affected their lives, they will no longer reject the use of paper money.

The reputation of the Dahua court is much better than that of the previous court, and the people have more trust in the court. Therefore, the promotion of banknotes is going smoothly, and it only takes a little more time. In the future, not to mention copper coins, even silver coins will be completely replaced by banknotes.
