"It costs a lot of money to erect a bell tower in front of the imperial city for free." Li Yi motioned for Bi Gou to eat.

"How much does it cost?" Bi Gou didn't listen to anything else now, so he asked how much it was.

"In our Datang, as long as the height is not too high, the bell is very useful, if you get to the mountain of 2,000 zhang, the air pressure is ......."

"How much is it?" Bi Gou interrupted Li Yi's words, he already felt the value of the bell, and did not use water leaks and hourglasses.

"As with the bicycle, it's mainly the stability of the clockwork, which involves ......"

"How much does it cost?" Bi Gou was unmoved.

"Nine hundred and ninety-nine." The price given by Li Yi in passing.

"Pay 50 percent tax on profits, and sell one to the household department for 500 yuan." Bi Gou solemnly gave the tax requirements.

Li Yi looked at Bi Gou carefully: "Old Bi, are you serious?" I said nine hundred and ninety-nine, and you admit it? ”

"No, it's that after careful calculation, my household department came up with the cost of your clock of nine hundred and ninety-nine yuan."

Bi Gou waved his hand, still so serious.

He didn't care how much money Li Yi made anymore, because he was sad.

The matter of making noodles in his own household was Li Yi's idea.

And then what happened? All kinds of benefits, but they can't fight other businessmen, and other businessmen still pay taxes.

Since Zhong can make money, let the Li family Zhuangzi make it, anyway, once Xiao Yi has more money, he will throw it out.

The same money, given to Xiaoyi, is guaranteed to be stronger than to his own household.

"Cheng, sell one and give you five hundred dollars, and I don't care if you want to issue collateral for small amounts of currency." Li Yi reached an agreement with Bi Gou.

"When taxes began to be collected in most areas of the Tang Dynasty, the imperial court issued its own paper money." Mention it.

He stretched out his chopsticks to dry the tofu again, and wanted to roll shredded pork in Beijing sauce.

Li Yi stopped with chopsticks: "You can't eat too much dried tofu, soy products, it's not easy to digest, it will ferment, and there will be a lot of gas in your stomach." ”

"The doctor said let me eat green onions properly." Bi Gou went directly to the green onions.

"Go get a pancake and cut it into cubes like dried tofu."

Li Yi commanded, Ziyu reacted the fastest, got up and rushed out.

"Yes, you can use bread rolls too." Bi Gou took a sip of the bowl containing the rice wine and scalded it.

He needs to regulate his body right now, mainly the gastrointestinal tract, drink ginseng whisker water or something.

After eating for seven minutes, Bi Gou left with five catties of big pine nuts, ready to go back and send them to the people in the political hall to eat.

By the way, use the knowledge you learned from Li Yi, well, the most important thing is to pretend to be knowledge.

Li Yi got up and went out for a walk, taking a medical class for a while.

Bi Gou returned to the political affairs hall, took out the pine nuts, and held a meeting.

At the meeting, he said that the people in the political hall were dumbfounded, and the economy can play like this?

Currencies are also divided into credit money and non-credit money? So is it true that if it is always a non-credit currency, it will put an end to the problem of currency depreciation in the economy?

Officials put forward the idea that it was always better to use a standard currency that had its own value.

Such as gold, silver, copper, gloomy wood.

Bi Gou nodded, indicating that he understood, and began to speak: "In economic activities, there is a relationship between supply and demand, and there are many people in demand, and the price of commodities increases.

On the contrary, the quantity of supplied goods is greater than the demand, and the goods are unsalable and reduced.

The same is true for currencies, where vouchers cannot provide sufficient quantities for circulation as economic activity increases.

The result is deflation, which must be replenished by other means, otherwise the economy will stagnate.

That is, to use the base currency in the early stage, and to add credit money in the later stage, unless we have more standard collateral......"

Bi Gou told the officials what he had learned from Li Yi, and there was a look of reverence in the officials' eyes, which made my Bi Zaifu amazing.

Su Ying and Song Jing also felt that Bi Gou was amazing, so much content, they could actually remember it after listening to it.

The key is that Li Yi really has goods in his stomach, and everyone knows that the currency problem is serious.

But it is only clear that too much bad money will make the money worthless, and then the price of things will be expensive, and we must find a way to stop it.

And Li Yi actually has a complete set of theoretical support, what kind of situation to deal with by what means.

Even if there is still bad money, Li Yi doesn't care.

Collect, especially the evil money with tin, and give it at a price higher than the price of other evil money.

By the way, I found a place to make tin for bad money, and I asked for the place directly.

If you encounter one, you will catch one, and the tin origin will be controlled, so how can you mix tin?

In addition, the copper coins with iron and the copper coins with light weight in the bad money are also collected by the Li family Zhuangzi.

The price given is fair, at least the person who sold the money did not suffer much loss.

Including the normal copper coins on the market, Kaiyuan Tongbao, at any time with the exchange coupons that can be exchanged for the same face value at Lijia Zhuangzi.

Li Zhuangzi controlled the issuance and circulation of the entire Jingzhao Mansion's currency, and extended it outward.

"It's already written in the book, go back and read and think more, if you can, don't spread it, accidentally spread it...... Anyway. ”

After finishing the lecture, Bi Gou said one last word.

The problem of external transmission, he found that it was useless to just read books, and it had to be combined with specific problems to suddenly understand, so it was.

The point is that the book is about concepts, not applications.

The officials said they understood, and one person grabbed a large handful of pine nuts and left, and they were reluctant to eat it themselves, so they went home to their families.

After everyone left, Song Jing said to Bi Gou: "Long Ze, do you think you can invite Li Yi to come over and give a special lecture?" ”

Song Jing knew that Bi Gou had told everything he had learned today, how much had he not learned?

"Xiao Yi will teach people to print out some things and pass them on to the students in Zhuangzi, and those things are not allowed to be kept, and they will be burned when they are learned."

Bi Gou shook his head, thinking that it was impossible, how could Li Yi teach it casually? Wow!

is much more powerful than Guiguzi, Guiguzi has learned a lot and is proficient in a lot.

However, compared with Li Yi, Guiguzi and the apprentices he taught did not have much achievement in people's livelihood.

It's more about the art of vertical and horizontal and the art of war, and it's very powerful to calculate other people's countries.

That's because I didn't meet Xiao Yi, otherwise Guiguzi would not be easy to use in any of the surrounding states now.

Xiaoyi's ability lies in making great efforts to deliver technology to the people, improve the yield per mu and save time.

At the same time, they don't play any tactics, and directly put money and weapons on it.

What kind of vertical and horizontal art and art of war can withstand hot air balloons, telescopes, and a large number of logistical supplies?

Waiting for the musket to come out, the strategy and tactics on the battlefield, when encountering the musket team, will be directly crushed.

You don't need to play any tactics at all, just push all the way.

"It's fine." Song Jing thought about it for a while, and found that he really couldn't teach it directly, what if it was learned by outsiders?

At the moment, others can only look at it, and then analyze the reasons, even if it is learning, what they have learned is only scratching the surface.

Not only can it not help its own country, but it may also trap the country.

For example, paper money, if it is difficult to imitate paper money, it may be counterfeited by others.

Or the people in power run out of money and try to print banknotes, that's great.
