In fact, the 10 million coins of copper coins were indeed a huge sum of money for the Tang Dynasty in the early days of Zhenguan. If Li Shimin wanted to cast so much money in a short period of time, even the old version of copper coins would still be a difficult task.

According to historical records, the highest annual copper coins in the Tang Dynasty in the early Zhenguan period were only 320,000 guan. However, during the reign of Emperor Zhenzong of Song Dynasty, the highest annual copper coins in the more than 5 million guan were not enough, so the earliest paper money appeared, Jiaozi.

Of course, the reason why there is such a small amount of minting is, on the one hand, because the currency circulation in the early Zhenguan period was not high. In addition to copper coins, silk in this period also belonged to the currency in circulation, and on the other hand, it was also due to the limitations of the minting process.

Of course, for Li Anran, casting copper coins is not a difficult task. The copper ore found in the territory of the Tang Dynasty, which was hidden in the rarely visited areas and had considerable reserves, was enough to support the manufacturing of huge amounts of copper coins.

In addition, each copper ore site is equipped with fully automatic manufacturing equipment. From smelting, purification, plate making, stamping, and the final product inspection, it is all done directly inside the equipment. Almost every second, a large number of copper coins and copper coins will be manufactured.

At the same time, such equipment is also available in the processing area of ​​the People's Bank of China. Coins that are collected into the treasury through deposits, investment, financial management, insurance and other businesses will be purified and refined in the corresponding production equipment in the processing area.

Then add the so-called "impurities" according to the proportion. Of course. Considering that the value of tin is higher than that of copper, it is naturally impossible to put the cart before the horse like the ancients. They use low-value metals and finally make new copper coins and copper coins.

As for the losses caused by this kind of currency reconstruction process, it is really not even a drop in the bucket for Li Anran. Not to mention, there are deposit management fees, and the profits generated by lending and issuing government bonds are nothing.

The reason why in addition to the copper coins that were promoted and circulated was to make old copper coins, the main reason was that each new copper coins was used as five cents, which is worth five ordinary copper coins, based on the prices in the early Zhenguan period. Although it was not unavailable, it was still inconvenient.

Just like in later generations, with the rise of prices every year, not to mention a cent, even a dollar can no longer buy anything, but a dime still has an indispensable value. Not to mention the heavens, even abroad is also indispensable.

Of course. The "super" currency represented by Zimbabwean coins with the smallest face value are in millions, which is naturally a different matter.

In fact, when manufacturing new currencies, Anran Lee also thought about using aluminum as the material for currency. Although this thing is a light metal, it has good ductility and a tough texture.

Even in humid air, an oxide film can be formed to prevent metal corrosion. The key is that this oxide film will not affect the beauty of coins like copper rust and rust.

In the period when cent coins were not eliminated, the three cent coins of one cent, two cents and five cents were made of aluminum. In addition to the light weight, the biggest disadvantage is that this thing is not resistant to burning. Even if it is just a little burning on the fire, it will turn black.

In addition to aluminum coins, Anran Li originally planned to make stainless steel currency. However, although this thing is relatively low in cost, it is much more troublesome to make than copper coins. After all, the composition of stainless steel is relatively more complicated and far less convenient than copper coins.

In addition, the people who want to let the people of the Tang Dynasty accept these two completely new currencies, to some extent, it is more difficult than accepting money tickets. After all, money tickets are directly linked to gold coins, silver coins and copper coins, which are completely different from aluminum coins and stainless steel coins.

After Li Anran handed over the first copper coin worth ten million yuan to Li Shimin, he was not idle. Instead, he went to the modern time and space that had not been back for a while and issued a purchase list to Hu Linger who was staying there.

After Li Shimin finished a 500 million chunk of public debt, he was very clever and did not ask for all the money. After all, fighting in battle seems to be spending money on the surface, but in fact, except for military aura, the rest must be replaced with corresponding materials.

Although Li Anran has been operating in the Tang Dynasty for about two years, especially after obtaining the multi-function exploration ship, he has indeed put a lot of effort into some basic industrial chains, such as the various minerals hidden in places where people are difficult to reach.

In addition, while building a sacred palace on the island of Taiwan in later generations, we also did not forget to open up a large number of farmland, fruit forests, fishing ponds, pastures, and the establishment of textiles, metallurgy, brick kilns and other industries closely related to life.

Even in later generations, I found various mineral veins with amazing reserves that are quite famous in modern time and space, and did some deep processing work when conducting large-scale mining.

But even so, he still had no way to take over the material consumption of the Tang Dynasty's military forces against the Turks this time. It was not long since Li Anran started to build a large-scale resource base, but was restricted by various aspects and his ability was limited.

Fortunately, the earth in modern time and space has a very complete industrial foundation. Although the technology level is a little worse, it is still enough to provide various materials for the Tang Dynasty, which is still in the era of cold weapons, to fight a battle.

Among all the supplies, the most important thing is not weapons such as swords, guns and halberds, nor armor, leather boots, helmets, but food and grass that are indispensable for people eating horses every day.

Food and grass, as the name suggests, is grain and forage.

The former is eaten by humans, but the latter is naturally used for horses and cattle and donkeys for picking up cars.

Although the value of a good knife is enough to match the amount of food, there is no need to say about the forage. But it cannot be held back. A good knife can last for a long time, but the food and grass are eaten a little less. The more battles, the more soldiers and horses they are consumed, the greater the consumption.

If there are too many, let’s take the number of 100,000 troops that are often written in Romance novels as an example. Although the rations used by an adult soldier to fill his stomach are not quantitative, in order to maintain physical fitness and combat effectiveness, it is not enough to eat less.

In ancient times, when fighting in modern time and space, even in the wild, you can rely on military rations to have meat and fish every meal, and even functional drinks, coffee, fruit and other auxiliary diets. That's not to think about it. It would be good to be able to eat enough on weekdays.

That is, before the fight begins, some meat jerky, jerky and other meat will be distributed on it to supplement the soldiers with enough nutrition. But even so, not to mention the amount of food this day, let’s calculate it based on a pound of grain. A 100,000 army is as much as 100,000 pounds.

Even if the ancient units of measurement were somewhat different from later metric units, after all, this account was just a rough calculation, so there was no need to be too serious. Even if a hundred thousand kilograms was 50,000 kilograms, it was only a 50 tons, and this was only a day's amount.

After a war, it would take for a year or two to last for so long. It would be necessary to count the process of marching, camping, retreating, etc. in a few months. Fifty tons a day, and 1,500 tons a day in thirty days. This number is really not small.

The price of wheat flour in modern time and space is about three yuan per kilogram, and one ton is three thousand yuan. One thousand five hundred tons costs about four and a half million. Even if the quantity is ordered, the cheaper the price is, it will not be too different.

What made Li Anran speechless was that the past mixed grain flour used to feed livestock was more expensive than wheat flour after being hyped up by the so-called dietary health concept. The only cheaper one was corn flour used as feed.

Fortunately, although this thing is made of feed, it is not impossible for people to eat it, and it is said to be quite nutritious. The only bad thing is that this thing is processed from genetically modified corn. Although it cannot kill people, Li Anran will never try it.
