The higher the level of the crystal card, the higher the storage limit, and the higher the production cost, because it is not a bunch of data stored in it, but real money.

After the gold, silver and copper are deposited into the crystal card, the balance will be displayed on the crystal card, and there are also virtual number symbols and transaction-related buttons on the crystal card, which is similar to the display screen of the mobile phone.

There will be a pair interface on each crystal card or card machine, so you only need to dock the two together and transfer the corresponding amount to each other when trading.

No matter how large the amount is, as long as the amount is determined, and then click to confirm the transaction, the money can be transferred to another card or card machine through the interface.

Because the crystal card itself is a high-tech magic weapon with internal space, they do not store data, but real gold, silver and copper, and there are two ways to take out the cash in the crystal card or credit card machine, one is to take it to the bank's ATM or staff for withdrawal.

There is also a way to directly use violence to damage the crystal card, so that the cash stored in the crystal card will also burst out, but in that case, the crystal card will be completely scrapped, generally only when you pick up someone else's crystal card and do not know the password lock, will do so, after all, the crystal card itself is also a valuable treasure.

"I—I don't have a crystal card, so let's pay in cash!"

Kun Shao scratched his head a little embarrassed, then took out one hundred and twenty gold coins and handed them to the cashier.

I saw that the cashier did not put the 120 gold coins into the credit card machine or the crystal card, because only the bank has the equipment to deposit gold, silver, copper and other cash into the crystal card.

Therefore, when everyone has too much cash in hand, they will go to the bank to deposit money and deposit the cash into the crystal card, which will be much more convenient for transactions.

Although the crystal card is very important, but in comparison, now Kun Shao and they need two first-level space backpacks, after all, the crystal card can only store money, and the space backpack can store various items, which is a must-have item for home travel.

"Hey, this sword is good!"

At this time, the sound of flowing clouds sounded in the store.

Kun Shao put away the alchemy talisman, then turned his head to look, only to see Liuyun looking at a short sword that emitted golden light.

"Blade of Sanctions!"

Kun Shao looked at the label under the short sword, and saw that the price was 1,800 gold coins.

The Blade of Sanction is a weapon suitable for Marksman-type heroes, which can increase the hero's physical attack and absorb Qi and Blood, restore one's own Qi and Blood and Stamina, and restore Qi and Health to pre-made enemies, similar to the "Nightmare Fang" wand used by the Mage.

"Here, wrap me up with this blade of sanctions. ”

Liuyun said, pointing to the Sanction Blade on the shelf.

"Okay, wait a minute!"

Soon, a shopping guide took off the Sanction Blade, then put it into the delicate sword box, and said politely to Liuyun: "This son, please come here to pay!"

Liuyun nodded slightly, and then walked over to the cash register.

"Childe, hello, a total of 1800 gold coins, do you want cash or a card?"

"Of course it's a credit card!"

After saying that, I saw Liuyun's hand wave, and a white crystal card appeared in his hand.

"Wow!"

When everyone saw the white crystal card in Liuyun's hand, they were all shocked, and they all looked towards Liuyun, the white crystal card can store 10,000 gold, which is a treasure that only rich people can have.
