The house is not the main one, but xuejue Xianwang and others noticed that some strange looking goods were sold in those small shops.

Zhang Daoling noticed that they seemed very curious, so he led them to a big "supermarket".

"It's called a supermarket. All the things sold in it are clearly marked. It's unique to Kyushu. It's different from the traditional market. Such supermarkets can be seen everywhere in Kyushu. You can buy anything you want at any time. "

"What you have on the shelf at hand is called drinks."

"It's called snacks on the right side, and there's spicy bar. It's very delicious. Come on, try it."

With a bad smile, Zhang Daoling took several bags of spicy strips and opened them for them to taste.

"I'll go. Why is it so hot?"

"But it's strong and addictive."

Snow Jue fairy king and coffin fairy King look strange. It's the first time that they eat this kind of strange taste, but they think it's very delicious.

Other people eat, but also quickly out of pocket to buy more bags.

"Shopkeeper, how to sell it?"

The shopkeeper is a little old man. He has long been familiar with these "country bumpkins" who are well-dressed.

"A bag of fifty cents."

"What's five cents?" A few people were stunned.

"Wumao is Wumao. You don't even know money, do you?" The shopkeeper was surprised.

"We know money. Is it a spirit stone?"

"No

"No?" The coffin fairy was confused.

Zhang Daoling had already prepared and smilingly took out a paper ticket. "This is money. It's the unified currency in circulation in Kyushu."

"Isn't it a spirit stone?" The coffin fairy was surprised.

"So is Lingshi, just a kind of currency in circulation."

Zhang Daoling thought about it for fear that they would not understand it. He worded: "this is the unified currency that can be used by all people in Kyushu, and Lingshi is of high value, so it is generally only used in large transactions. It's good to use this kind of currency in our daily life. "

"Oh, well, how to use it? Buy it directly? " The coffin fairy is like a curious baby.

"Yes."

Zhang Daoling nodded, "this kind of currency is issued by the government. It can be used everywhere, and there is no need to worry about forgery. Ordinary people can't forge it. According to the above denominations, it can be divided into 10000, 5000, 1000, 500, 100, 50, 20, 10 yuan, 5 yuan, 1 yuan, 5 Mao, 1 Mao and other denominations. With this, you can buy anything. "

The king of coffin suddenly wondered, "in the past, there was not a spirit stone as a trading currency. It doesn't sound very troublesome for you to use this kind of currency."

"No trouble, not at all. On the contrary, it's much more convenient than before."

Zhang Daoling laughed and explained: "the Lingshi is of great value. At present, a piece of inferior Lingshi on the market is priced at 10000 Kyushu dollars. And ordinary people may not make so much money a year. How troublesome is it to spend a stone? What's more, if you want to buy something of very small value, how can you pay for it? For example, things like this supermarket, a stone can buy a lot of things. But ordinary people can't use so many things in their daily life. "

"More importantly, with this new currency, you don't need to hoard any more. You can buy whatever you need at any time. Not only is the mobility of goods improved, but life is also convenient. "

"In addition, the currency of the whole country is unified and can be used everywhere. There is no such thing as before. A piece of stone with different value in different places causes all kinds of disputes and hinders the development of trade."

"You say it's more convenient? Or is it more troublesome? "

After hearing this, everyone was surprised.

Snow Jue fairy King took a breath and felt awe inspiring. Just listening to Zhang Daoling's explanation, he could feel the terrible value of this change.

"Shopkeeper, how much did they buy just now?" Zhang Daoling asked with a smile.

"Ten dollars in all." The little old man said casually.

"Wechat?"

"All right."

Under the incredible eyes of Xue Jue Xian Wang and others, Zhang Daoling took out a mobile phone!

"What's that?"

"It's called a mobile phone, and it's also something of the lower world. I don't know how to play with it, but it's said that it's very convenient for me to do something about it." Zhang Daoling poked his finger on the screen of the mobile phone several times, but he didn't know how to do it.

"Cough, let me do it."

At this time, Li Xuanwu in the crowd came forward, took the mobile phone, then opened wechat and showed his payment code.

The shopkeeper took out the machine on the cash register and swept it.

"Drop!"

Seeing this, Zhang Daoling sighed and shook his head, "it's still you post era people who can play. Anyway, after studying for so long, I still can't understand it.""That's paid?" Snow absolute fairy king and others see a face muddle force.

"Yes."

"Just sweep that thing? Isn't there no money? " The coffin fairy pointed to the money in Zhang Daoling's hand.

Li Xuanwu was dumbfounded and shook his mobile phone. "It's called a mobile phone. Although it's not popular in Kyushu, it's already available in major urban areas. See those two icons on the door? It's called a two-dimensional code. "

"What is a QR code?" People are more puzzled.

"I really can't explain this for a while. It's from the lower boundary. It's very complicated. Take your time on the way out. "

After leaving the supermarket, the coffin fairy king and others were eating spicy strips while listening to Li Xuanwu's explanation.

"The place where we live is called the fairyland. If we practice, we will have the power of all kinds of laws, the power of the great way and so on. But there are many things that can't be seen by the naked eye, such as light waves and electromagnetic waves. It's ok if you don't understand them. In fact, I don't quite understand them. This is the technology developed by human beings in the lower world where I used to live. With the help of various machines, they have analyzed many things that can't be seen by the naked eye. "

"For example, it's noon and the sun is hanging in the sky, isn't it?"

Everyone looked up, and now the sun was shining.

"The light emitted by the sun is not just light. Through scientific and technological analysis, we can analyze a variety of colors, including red, orange, yellow, green, cyan, blue and purple. What the naked eye can see is only transparent color. Sometimes when it's raining, you can see the rainbow. The rainbow is seven colors. In fact, those seven colors are part of the sunlight

When Li Xuanwu explained, he specially asked the people who took pictures behind him to record his words.

This is what we want to show to the people in other fairyland cities in the future, so that they can see all the extraordinary aspects of Kyushu now, and they are willing to be loyal to Kyushu from the bottom of their heart.
