Sure enough, as Fang Ru and Granny Su expected, the Strangers heard about the strong charm and quickly discovered its value.

The Giant Clans were the first to arrive, and they didn't have long to go, and several more batches came one after another. Some of them are polite, like a businessman, while others are like giants and want to solve problems by force. Fortunately, Fang Ru was well prepared, and Granny Su was also like a person, not to mention turning danger into disaster, and successfully squeezed out a lot of real money from the superpowers.

In addition to the strong charm, the giant team was also curious about whether the so-called "Mr. Wu" had any other magic weapons. Fang Ru and Granny Su were keenly aware of business opportunities, and they increased the variety of goods that night, and soon increased the purchase.

After a week, Granny Su and Fang Ru were very tired. Needless to say, Granny Su directly dealt with these people who could kill a zombie with a wave of her hand, and the physical and mental pressure was not small.

Fang Ru was not at ease, and stayed not far from Granny Su twenty-four hours a day. Mother-in-law out of the stall she wandered in the market, mother-in-law home she lay in the corner, mother-in-law walked on the road between the market and the house, she lurked in the bushes on the side of the road to follow, ready to help mother-in-law solve the armed negotiations, this is called a back pain leg cramps.

"I'm more and more curious about Granny Su's past." The pot is amazing.

Not everyone has the ability to seek skin with tigers.

"I want to know too...... Oops. Fang Ru straightened up from behind the bushes on the side of the road. Her old waist rattles.

It's eight o'clock in the evening. Many of the Adepts are reluctant to crowd with the ordinary people who come to the market, and there are many people during the day. It was inconvenient for them to have a deep conversation with Granny Su, so most of them came back in the early morning and at night. Mother-in-law and Fang Ru were also happy. So in the past few days, a convention has gradually formed: the old woman's stall surnamed Su, when the sun comes out, is just an ordinary stall, but once the sun leaves the sky, you can buy some wonderful things from her.

The mother-in-law had just sent away a group of supernatural people and was packing up her things: "Girl, you are here." ”

This doesn't sound surprising at all.

Fang Ru held his waist and limped out of the grass. "Mother-in-law, are you still smooth?"

"Can't you hear me?" The mother-in-law smiled kindly. It's like treating a granddaughter who loves to play tricks. "Come, drink some hot tea to warm up."

Fang Ru was as kind as a stream, and took the teacup. It's getting hotter, but it's still cool at night. I don't know when this kind of day is going to be stripped off during the day and wrapped into zongzi at night.

"I didn't hear it today." Fang Ru said. She ran out of listening potions. The small fish are too cold at night. Nest at home and don't go out.

Mother-in-law sighed. From the drawer on the counter, he took out a wad of banknotes and a flannel bag containing jewelry: "Team Lily of the Valley bought five strong charms. There are also three bottles of super acid. They don't have enough money and replace it with this. ”

The mother-in-law opened the cloth bag and poured out a crystal clear from it.

Fang Ru's breath suddenly stagnated.

"I've never seen a gem like this." The mother-in-law looked solemn. "This thing looks like crystal, but it doesn't look like it."

How worthless jewelry and gemstones are in the base, the mother-in-law knows better than anyone else. In the past, people might have fantasized that they could escape from Jing'an City and go to a safe place to escape, so they came to her to pick up leaks, but now that the whole country has been invaded by the zombie virus, her jewelry is completely unpopular.

The Stranger swore that this thing was very valuable, and if she didn't accept it, she would anger them, so the mother-in-law accepted it.

"They didn't say where they got it?" Fang Ru asked.

The mother-in-law was a little speechless. "Say yes...... Gouged out of a zombie's head. ”

A big word suddenly popped out of Fang Ru's mind: Damn!

Isn't this the crystal nucleus?

"Does this thing have a name?" Fang Ru hurriedly asked.

"It's said to be called ......," the mother-in-law thought about it carefully, "That's right, it's called the crystal nucleus." Hey, my brain just told me, turn your head and forget. ”

“……”

It turns out that there are some old customers in the top management of the base?

I've never heard that there is a crystal nucleus in the zombie's head, and she thought that there was a gap between reality and fiction, so it was waiting for her here.

Fang Ru silently raised his middle finger towards the sky in his heart. Jade Emperor children's shoes, is it really good for you to follow the trend like this?

However, as an otaku who loves to read online novels, Fang Ru still has a high acceptance of this term. "How much do they use this top?"

"Except for this wad of bills." Mother-in-law said.

Fang Ru took the thick pile of banknotes in her mother-in-law's hand. Her hands are not small, but they can barely hold them. After roughly counting, Fang Ru was very surprised: "So many? Nine out of ten? ”

In other words, the thick banknote accounted for only one-tenth of the transaction.

It is conceivable how much money Fang Ru has made in the past few days.

The mother-in-law nodded: "Listen to them, the base has the idea of using crystal nuclei instead of banknotes as currency." Each zombie has only one crystal nucleus in their brain. The number of crystal nuclei is equal to the number of zombies killed. ”

It is equivalent to how much effort is contributed to the base.

I heard Qin Shen say before that the base calculates the battle merits by the number of severed zombie heads. Congratulations to the base for finding a new solution that is clean and clear.

"No wonder the inflation in the base has been so strict recently." Fang Ru said. In just one week, prices in the base doubled. All of a sudden, there were fewer people visiting the market. It seems that it will not be long before the base will implement a truly planned economy.

Fang Ru was not surprised by this. The price of goods in the base is so high, isn't it the high-level of the base that made money by the way in order to force ordinary people out of the base to be cannon fodder? Now that the whole country has fallen, there is no need to collect money, and isn't it more convenient and effective to use crystal nuclei as bait to lure people out of the base?

"It looks like cash won't last more than a few days at the base." Fang Ru returned the money to her mother-in-law, "In the future, when the supernatural people come to buy things, it is best to have crystal nuclei." All the cash you have at home can be exchanged for supplies. ”

A look of embarrassment flashed on the mother-in-law's face. "You're going to spend the cash...... But now the flowers, will it not be worth it? ”

You must know that the materials in the base are actually quite abundant. After all, the entire Jing'an City is so big, and the survivors can be fully equipped with just one university. Using the daily necessities of the city's nearly one million people to feed these less than tens of thousands of people, there is still no pressure for a while.

This is also the fundamental reason why the cash economy of the base did not collapse immediately.

After all, the crystal nucleus has only appeared, and no one can be sure what the relationship between the crystal nucleus and the zombies is. In Granny Su's opinion, even if cash has no purchasing power, there are many people in the base, and a symbol of exchange is needed. Banknotes themselves are currency symbols, so why can't they continue to be used.

Of course, the most important reason is......

Fang Ru's eyes changed when she looked at her: "Mother-in-law, is the money I gave you out of your hands?" (To be continued......)
