"It's not early, we have a special task tomorrow night, we must maintain full energy, then we will go to sleep first. ”

Kun Shao said a word to the old man and Teacher Su, and then took his classmates up to the third floor together.

The third floor is a small world belonging to Kun Shao and Cai Ji, and two spacious bedrooms are each furnished with a huge modern bed.

Kun Shao said to Bijun: "You three girls sleep in one room, and we three boys sleep in one room, so let's squeeze it!"

"Hmm!"

Bijun snorted and didn't say anything more. Meiyan said half-jokingly: "Anyway, Sister Cai Ji is so young, she doesn't take up any space at all, and she can sleep well." ”

"Giggles!"

Everyone laughed, the atmosphere suddenly became a lot more lively, and after this period of contact, the relationship between the three girls also improved a lot, just like the three sisters.

Day 2......

Everyone got up early because they still had a lot of work to do today.

Bijun needs to use the first-order ice crystal nucleus that Bi Lei gave her to make a frost staff, and since the crystal nucleus used is a first-order product, the frost staff she makes is also a first-order level.

Compared with the first-order Frost Staff and the second-order Frost Staff, their initial attributes will be very different, and the most direct way to improve their attributes is to strengthen Yunyuan.

The necessary item to strengthen the weapon is the Enhancement Runestone, or Enhancement Stone for short.

And this kind of enhanced Yunyuan rune stone is refined from crystal stone, one crystal stone can refine ten pieces of enhanced Yunyuan rune, so the market price of crystal stone is 10,000 gold coins.

The Crystal Yuan Stone can not only be used to refine into a strengthened Yunyuan rune stone, but also to refine the Yuan Dan that can be used to improve cultivation.

Similarly, a piece of Crystal Yuan Stone can refine ten Yuan Dan, Yuan Dan is ten times better than Energy Dan, so its price is also ten times that of Energy Dan, the market price is one thousand gold coins, and taking one Yuan Dan to cultivate for one night can improve one's cultivation for one hundred days.

Therefore, the price of Yuan Dan is similar to that of Yipin Nei Dan and First-Order Crystal Nucleus, and the market price is 1,000 gold coins.

The three currencies of gold, silver and copper are more popular in the ordinary market, but the most popular currency in the cultivation market is the crystal stone, because the crystal stone can not only be used to refine the Yuan Dan to improve cultivation, but also can be used to refine it into a strengthening Yunyuan rune stone to strengthen equipment.

Therefore, in the cultivation market, the largest unit of currency is not gold, but crystal!

The so-called crystal is the crystal stone.

The conversion formula for this world currency is as follows: 1 silver = 100 copper, 1 gold = 100 silver, and 1 crystal = 10,000 gold.

Therefore, the largest monetary unit is crystal, and it is precisely because of the emergence of crystal stone that it is convenient for everyone to trade a huge amount.

After converting gold into crystals, the data is naturally reduced a lot immediately, 10,000 gold is equal to one crystal, then 100,000 gold is 10 crystals, 1 million gold is equal to 100 crystals, 10 million gold coins are equal to 10,000 crystals.

Just imagine, if you carry 100 million gold coins on your body, how heavy is it? Even if you use a crystal card, you need a level 6 green crystal card to be just able to store it, in contrast, it will be much more convenient to carry 10,000 crystal stones, after all, not everyone can afford to buy a level 6 green crystal card, and a high-level crystal card is a status symbol, even if you have money, you may not be able to buy it.

This shows the preciousness of the Crystal Stone, and the enhanced Yunyuan Rune Stone refined from the Crystal Stone is naturally a rare treasure, and now Bijun and they don't dare to think about it at all, and there is no need.

The price of a first-order ice crystal nucleus is one thousand gold coins, and the wand made from it can only be sold for two thousand gold coins at most, and the price of a strengthened Yunyuan rune stone is one thousand gold coins.

So no one would want to waste an enhancement Yunyuan rune stone on an ordinary piece of equipment.
