Originally, in addition to copper coins, the currency of the Tang Dynasty also included silk and other items, and copper coins were only one of the ways of trading.

But the system only accepts copper coins, and Cao Ze can only refuse other payment methods.

After receiving the silk silk, you have to resell it again, which is too troublesome.

After hearing Cheng Chumo's words, Cao Ze pondered.

Datang's payment method is too troublesome.

Not to mention the mobile phone payment of later generations, there is not even a banknote......

Not only are the guests troublesome to carry copper coins, but it is also a hassle to count the money when settling accounts.

It's okay to say in a short time, and the guests are eager for the delicious meal, so they put up with it.

But after a long time, there will definitely be problems.

Why don't you discuss with Lao Li about launching banknotes or running a bank?

It doesn't seem to work......

The implementation of paper money should be based on banks.

Datang is now poor and white, and this bank can't do it no matter how you look at it......

When the time comes, not only will it not be successful, but it will also cause a lot of trolls and trouble for yourself......

And even if everything goes well, it won't be implemented in a while.

What I need right now is something that can replace copper coins in restaurants.

Ordinary license plates and the like are definitely not good, and it is difficult to do a good job of anti-counterfeiting.

Unless there's something that no one else can imitate......

Thinking of this, Cao Ze suddenly had an idea.

Wait a minute......

Looks like I have it handy!

Cao Ze flipped it over casually, and a chip appeared in his hand.

That's right, Cao Ze thought of this plastic chip!

Plastic is absolutely anti-counterfeiting in Datang, and other human beings can't imitate it!

If only someone could get plastic out now......

Then Cao Ze will not only not blame, but will also be arrested and used as a talent!

The chips themselves are divided into different denominations, which is similar to the soft girl coin!

And this thing is very exquisitely made, and it is very high at a glance!

Go back and divide these chips into different denominations and use them as money in the restaurant!

At that time, customers will no longer be bothered by a large amount of cash, and it will be much easier to pay!

Cao Ze believes that these rich people in Datang will soon fall in love with this new payment method!

And that's not all there is to it!

After turning back and creating a new industrial shop, you can completely promote this payment method to the new shop!

In the future, my own shop will use this payment method, so this chip is equivalent to becoming a new currency!

Although it is only circulating in a small circle in the short term, it is enough!

Later, when people gradually get used to this convenient payment method, there will be a basis for going back to banks and paper money!

And the emergence of banks and paper money has undoubtedly promoted the society!

Of course, it's a bit early to talk about that.

Now let's solve the problem of the restaurant first.

"Immortal Master, what is this?" Cheng Chumo was immediately attracted by the bells and whistles: "It's weird and good-looking." ”

"That's good stuff." Cao Ze threw the chips in his hand.

Cheng Chumo picked it up and looked at it.

This thing is only an inch in circumference, and it is painted with a circle of beautiful red patterns.

Right in the middle is a small dotted blue circle with several numbers written on it.

Because he also listened to Cao Ze last time when he taught Arabic numerals, he also recognized the numbers.

“1000？” Cheng Chumo wondered, "Immortal Master, what does this mean?" ”

"That's what it always means." Cao Ze smiled slightly.

"Is this your Zuan's money?" Cheng Chumo suddenly said: "It's so good-looking." ”

"No, no, no." Cao Ze replied with a smile: "In the future, it will be the money of our restaurant." ”

Cao Ze said as he took out a few more chips.

After Cao Ze's explanation, Cheng Chumo finally understood.

The numbers on these things represent the text.

"Immortal Master ......" Cheng Chumo seemed to think of something: "You mean to let the guests exchange the money for this kind of thing to use in the future?" ”

"Hmm." Cao Ze nodded.

At the same time, he sighed in his heart, worthy of being Cheng Yanjin's son.

Although the father and son look like a simple man, they are actually thieves......

"This thing is good!" Cheng Chumo sighed: "Not only is it easy to use, but others can't imitate it!" ”

At about ten o'clock in the morning, the two set off in a horse-drawn carriage.

Cao Ze had already seen it before.

The sales in the mall are very user-friendly.

The four pieces of the mahjong set can be purchased separately, and the prices are all very cheap.

Plastic chips are a hundred pennies, and the face value is arbitrary.

Compared with the 10,000 draws, this cost is negligible.

By the time they arrived at the Drunken Immortal Residence, it was almost eleven o'clock.

The restaurant is still full, and there is still a lot of queue outside the door.

For nothing, the people of Datang showed full enthusiasm!

I can't help it!

After eating the food of Zuixianju, I couldn't eat the food of other restaurants anymore......

Not to mention spending money, I don't even bother to use chopsticks for nothing.

However, Drunken Immortal Residence didn't really let other restaurants in Chang'an City close.

After all, the Drunken Immortal Residence is so big, it is impossible to accommodate all the guests.

However, the people who go to other restaurants to eat are the kind of rich people who are not very rich, and Drunken Xianju has always made a lot of money.

After handing over the front desk to the second shopkeeper to take care of, Lu Dage excitedly went up to the fourth floor.

"I've seen the owner, I've seen the little grandfather." After entering the door, Lu Dage saluted respectfully.

Cheng Chumo naturally didn't need to say more.

As a little grandfather, he naturally didn't dare to slack off.

For Cao Ze, Lu Dage couldn't be more respectful!

After all, Cheng Chumo was so respectful to Cao Ze, and he didn't dare to slack off.

And on the day of the opening, he watched Lu Guogong take several nobles up to the fourth floor.

Especially when he saw Cheng Yanjin's attitude towards the man and his wife in it so respectfully, Lu Dage was so frightened that his heart almost jumped out of his throat!

There are really not many people in the world who can make Lu Guogong so respectful!

The last time you have to start with the prince, right?!

And ordinary princes can't do it!

It could even be the one!

Thinking of this, Lu Dage didn't dare to think about it at all.

After all, this kind of thing is no longer in the category of what he should know, and it is not good for him to know too much!

Later, after seeing Cao Ze enter Cheng Biting Jin's private room, Lu Dage knew that he had hit a big luck!

"Shopkeeper Lu, sit." Cao Ze smiled and gestured.

Lu Dage hurriedly sat down.

But the butt didn't dare to sit down, and only occupied a chair corner.

Sitting on pins and needles may be the best description of how he feels now.

If he could, he would rather still stand......

"Shopkeeper Lu." Cao Ze pointed to the chip coins on the table: "In the future, our restaurant will use this thing instead of copper coins." ”

Then Cao Ze explained the purpose of the chip coin.

These things are not complicated, Lu Dage understands them after listening to them once.

"Boss, this is really a good thing!" Lu Dage sighed: "With this thing, it can indeed save the guests the trouble of carrying copper coins." And it is also very helpful for the implementation of our fart-only system. ”

"It's just ......" Speaking of this, Lu Dage was embarrassed: "I'm afraid that the guests won't agree......"

After all, it's a novelty.

I'm afraid that the money is not so easy for people to accept in exchange for this thing.

"Don't worry about that." Cao Ze replied: "In fact, this thing is similar in essence to the traditional way of saving money, you just have to recommend it to the guests." ”

"Whoa." Lu Dage hurriedly responded.

"This box is full of these chips." Cao Ze pointed to the box on the ground and said, "Get these for the time being, it's not enough to turn back, you just send someone to the Lu Guogong Mansion to say it." ”

Cheng Chumo got up and walked over to open the box.

At this moment, there was a sudden commotion downstairs.
