"You father and son, you can't talk about anything well, you have to blow your beard and stare at your eyes" Empress Eldest Sun walked in and glared at the two of them fiercely.

As soon as I came in, I saw two people staring at each other.

Empress Eldest Sun shook her head helplessly.

This father and son

When you don't meet, you miss each other, and when you meet, you bite each other, it's like a dog

"Qingque, you are a child, you should let your father order, Erlang, you are a father, what can you see like Qingque" Empress Changsun said gently: "You two, both give each other a step, the dignified father and son of the heavenly family, like two vindictive children, what do they look like"

"Mother, you're here" Li Tai greeted him with a smile.

He put down a brocade box and said, "Mother, I brought you a treasure."

"Hmph" Li Shimin heard this, snorted coldly, and said: "It's not enough to deceive the minister, I still want to deceive your mother."

Li Tai rolled his eyes.

I really want to shout: Daddy, come on, hurt each other

"Mother, please see." Li Tai opened the box.

Empress Eldest Sun came over to take a look, with a hint of doubt on her face, and asked, "This is the pastry in your house."

"No, it's soap, aka soap." "It's much easier to use than pancreas, and when we made it, we added some spices to it, and it was fragrant when we washed our hands," Li said. ”

"It's okay to wash clothes and take a shower, even if it's to wash your hair, it's fragrant." Li Tai said with a smile.

"Oh," Empress Eldest Sun said, looking at the soap that looked like a cake block, "This is from overseas again."

"Yes." Li Tai nodded, and then ordered someone to go and fetch a plate of water to come back.

I personally made it and washed my hands that were originally a little dirty.

He said: "Mother, with this thing, it will become easier to clean and clean in the future." ”

"Sure enough, after washing, my hands feel a lot cleaner, and they are fragrant." Empress Eldest Sun said with great satisfaction.

This is the son's filial piety.

Well, it's really great.

Empress Eldest Sun didn't seem to realize that she had become an advertising spokesperson.

Li Shimin watched from the side, and his nose let out a dissatisfied sound.

"Dad, I also brought you a gift." Li Tai opened another box and saw two horseshoe gold in the box.

"Yes"

Li Shimin's brows furrowed slightly.

snorted coldly and said, "I don't lack your money."

"Dad, haven't you noticed that there is any difference between these two horseshoe gold," Li Tai said with a smile.

"What's the difference between this color" Li Shimin picked up two horseshoe gold and said: "The right side is more dim, the left side is brighter and more golden, and it is also heavier." ”

"I said if it's on the left, it's pureer, do you believe it?"

"Seriously"

"Fake." Li Tai said: "This piece of horseshoe gold, I added two taels of brass, and the purity of the gold cast is much less than the gold that looks dark and red at this moment. ”

"However, I don't say it, who knows that there are two taels of gold in it, and I put this gold on the market, and then let people brag everywhere that this gold is real pure gold, what do you say" Li Tai said with a smile.

"Hiss"

Li Shimin couldn't help but gasp.

When he looked at Li Tai, he couldn't help but secretly admire.

This son of his own is really black-bellied

When two taels of brass are bought with two taels of gold, it is estimated that the aristocrats of the entire Tang Dynasty are eager to buy it, after all, the color of this gold looks more beautiful and more golden.

"Dad, this thing, but it's a baby" The smile on Li Tai's face brightened.

Li Shimin pondered for a while, and then said: "If this is the case, wouldn't it be possible to use brass as gold?"

"Dad, you really want to be beautiful, you can't add more than 20% of the brass, otherwise you will be exposed." Li Tai said, I still want brass to be used as gold, do you think that the nobles of the entire Chang'an City are fools

It's really okay to fool ordinary people, after all, ordinary people have never seen gold in their lives.

However, it is not easy to fool those families.

Datang's gold is basically in the hands of the family, why is this so

Because the family is rich, really rich

Ordinary people, basically, have a few times a year to be considered rich.

"That's a shame." Li Shimin sighed.

"However, it can be used elsewhere." Li Tai said.

"Yes"

"Minting"

"No, no." Li Shimin shook his head and said: "If the coinage is less copper, it will be broken. ”

"Moreover, a large number of bad coins appear in the market, which will affect the economy of my Datang, which is not feasible and not feasible." Li Shimin said.

"What if others don't recognize it," Mr. Lee said.

"How can you not recognize it" Li Shimin showed a trace of doubt on his face, good or bad, you can see it at a glance, okay

"Dad, we can create a new type of currency, called Shiwen currency, and mint it with tin in the copper coin, if you don't avoid the currency, you basically can't see it."

"We can also make some silver coins, silver coins of seven coins, we can use them for one or two." The more Li Tai said, the more energetic he became: "In the future, we can also mint gold coins, with copper in between, which can also be used as pure gold." ”

"This" Li Shimin hesitated a little, and said: "Let's try the copper coin first, this gold coin and silver coin are too shocking, inappropriate, inappropriate." ”

"Yes, let's try the copper coins first." Li Tai was very happy, it seems that Li Shimin agreed.

In this era, the legal currency is Kaiyuan Tongbao.

However, there are still people who use cloth and brocade as currency, and some people also use pepper as currency.

When Yuan Zai, the prime minister of the Tang Dynasty, was raided, he copied out dozens of tons of pepper, which can be called huge greed. People in later generations must think it's funny, dozens of tons, even if they can't eat it every day, what is there to be greedy

In this day and age, pepper could be used as currency.

In ancient Rome, you had a bag of pepper and you could flaunt your wealth everywhere.

Gold and white eyes are only used in large-scale transactions, after all, they are scarce, such as the construction of Daming Palace and the Imperial Palace, which requires good timber and good bricks, which have to be traded with merchants.

"This matter needs to be done secretly." Li Shimin thought about it and told Li Tai, "You must moisturize things silently, but you can understand"

"I understand, I understand." Li Tai smiled, it seems that his father is actually quite treacherous.

Gold, yes, I can give it a try, too.

Silver, yes, I can give it a try, too.

Copper coins, got it
