"Lao Bi, you can't do this, it's not my Li family Zhuangzi, you have to give me the collateral of the exchange coupons."

Li Yi looked at Bi Gou fixedly, stretched out his hand, and asked for something.

"What for you?" Bi Gou looked down at Li Yi's hand, which was slender and suitable for playing the piano.

"Give me gold, silver, and brass." Li Yi shook his hand a few times.

"Why?" Bi Gou didn't want to give anything, and no one else had given anything to the exchange coupons of the Li family Zhuangzi before.

"You're taking advantage of it, you look at the voucher as a penny, but it's actually in circulation.

Each time it circulates it it adds a little bit of tax, and the more times it circulates, the more tax it corresponds.

Theoretically, it circulates thirty times, thirty taxes and one, and you can get a profit of its own value.

But the cost is not, it needs to be turned over more than 300 times before I can pay back.

But I haven't received the tax, which is equivalent to the currency issued for you, you think about it, isn't it? ”

Li Yi is reasonable, as he said at that time, the country loses money if a dime is issued.

Purely from the point of view of manufacturing, it is a loss, but the dime is circulated again and again, and the tax generated far exceeds its own value.

The most profitable is actually the one-dollar coin, which wears out much less than other banknotes.

Of course, the most money-saving is digital currency, and the state saves money.

Then part of the cost is passed on to the people, who need to download the software and then pay for it with the software.

Is there a cost to buying a mobile phone? Traffic has a cost, right?

There is no other traffic business, open software payment, a traffic costs about two cents, even if the thing bought is one yuan, the additional payment is 20%.

Unless the software of digital currency is free of traffic, it is to reduce the cost of national currency and increase the international competitiveness of the national currency.

Then let the people of the country pay additional traffic fees, and this expenditure is regarded as a subsidy to telecom operators?

As for other software, it is a commercial act, and this is an act of the state, which should not be confused.

At present, the cost of the penny issued by the Li family Zhuangzi is higher than the face value.

If you can't earn it back, you need financial subsidies from the imperial court, and every time the currency is circulated, it has nothing to do with the Li family Zhuangzi.

The tax revenue generated by it was taken by the imperial court, so you have to give something, otherwise you don't want to issue the currency of the Tang Dynasty in the future, otherwise it will hit you to death.

Bi Gou sandwiched shredded green onions and shredded meat onto the dried tofu and rolled a roll with chopsticks: "According to what you said, the money has been circulating back and forth, and then the imperial court collects taxes."

In this process, it is inflation, the same thing, with a lot of turnover rate, represents currency depreciation, right? ”

Bi Gou felt that he had learned the essence, and it was so simple.

Li Yi still smiled: "Purely in terms of currency, every circulation involves taxes, and the face value of the currency has not changed, which is a depreciation." ”

"But." Bi Gou understood, helped Li Yi say it, and he knew that there was a turning point.

"The circulation of money, which involves the productive forces and the relations of production, whether it depreciates depends on whether the purchasing power of money for a product has decreased.

It turned out that I had two stones of wheat per acre, twenty-five dollars for one bucket and two hundred and fifty dollars for one stone.

Now I produce four stones of wheat per acre of land, and according to the laws of economy, the price will inevitably be reduced, 20 yuan per bucket, 200 yuan per stone.

At this time, the currency did not depreciate, and the purchasing power increased, even if it took on taxes in the process of circulation. ”

Li Yi gave the simplest example and told Bi Gou that the tax in the process of currency circulation cannot be calculated separately.

At the same time, it is necessary to calculate the change in the national productive forces, which are higher than the taxes paid when money is circulating, and the value of money increases.

"When the currency is issued as collateral in kind, there is basically no depreciation of the currency, unless there is a natural disaster for the whole Datang.

But at that time, tax exemption and imperial court monetary support could be carried out, subsidies could be given, and the value of the currency could be balanced again.

Lao Bi, don't be afraid of problems with the exchange coupons of the Li family Zhuangzi, it is impossible, because as much currency is issued, I will prepare as much collateral as possible. ”

Li Yi made it clear that the currency I issued was not a credit currency, but an unleveraged exchange certificate with equivalent collateral.

If you say it's a voucher, it's a voucher.

It is different from the national credit currency, which is directly linked to the physical object.

Bi Gou began to scratch his head, how to get money, it is so difficult to learn by himself? How much is involved, exactly?

"Should I give you money now? No, gold, silver, copper? "Bi Gou finally returned to his normal state and figured out the key points.

"No, you just need to give me the same amount of tax exemption, and I will buy collateral with the money saved from tax exemption."

Li Yi shook his head again, Lao Bi, you still don't understand.

"But I've always given you tax exemptions, and now I feel like I can't stand your taxes anymore, and you always find reasons for me not to take your money."

Bi conceived to get into Li Yi's head, and then learned all the things that Li Yi would have.

"I have something new to come up with, and I want to give this tax exemption." Li Yi nodded and whispered.

"You tell me something, otherwise don't think about it, otherwise the old man will crash and die on the pillar of the Baqiao, do you believe it or not?"

Bi Goucai is not fooled, he is cautious, afraid of being calculated by Li Yi.

"How can there be someone like you? You threaten others with your own life, why don't you just kill me? It's all a death anyway.

Anyone who threatens others with his own life is a weakling, and he is not afraid of death, so why not drag the enemy to die together? ”

"Then tell me what it is, the old man has lived enough." Bi Gou's eyes widened, and he looked like he was ready to die with you.

"You look at the time with me, always look at the watch, it's an electronic clock, I can't give it to you, let alone sell it.

Everyone now uses hourglasses and water leaks to keep time, and at the same time looks at the sun, moon and stars.

I have something, a mechanical clock, a clock made by calculating the pendulum according to the latitude and longitude of our Chang'an.

The accuracy of this clock is different in different places, and it is the influence of gravity that allows me to build an escapement due to the lifting of steel.

I'm going to make a chiming clock, and I'll ...... when the time comes. It doesn't really matter, the main thing is that it can be timed. ”

Li Yi threw out a new technology product, Zhong.

In addition to the steel and escapement design, the local gravitational acceleration must also be considered.

At the equator and Chang'an, the oscillating clock will be skewed because the earth is not round, but elliptical.

The autobiographical angle of the earth should also be taken into account, and the pendulum clock has an error, which will become larger and larger, and must be adjusted.

This is easy to solve for Li Yi, he has information to check, just adjust the length of the pendulum.

"How much are you going to sell?" Bi Gou looked up at the electronic clock, he knew this thing, and sometimes he specially took his own hourglass to pair it.

"I'm going to build a bell tower for free to help everyone determine the time, but in fact, the technology of the water armillary sphere will do." Li Yi didn't say the price.

"How much does it cost?" Bi Gou doesn't care about anything else, grasp the main point.
