"What's wrong?" In this strange atmosphere, although Fang Lingxin was curious, she didn't dare to make a loud noise, so she approached Zhou Tian and asked in a low voice.

"I only found one such place, but I didn't know that the transactions here were either bartered or received not money, but high-quality black jade." Zhou Tian smiled bitterly.

As he spoke, Fang Lingxin also noticed that there was a stall in front of him that was trading, the stall was set up by a middle-aged fat man, and the guest was a young man who looked like he was in his thirties, and he was looking at a gourd-shaped object, the middle-aged fat man stretched out his hand to compare, and the young man also stretched out his hand to compare, and finally it seemed that it was a deal, and the young man took out three black jade stones the size of his little finger and handed them to the middle-aged fat man, and then happily put away the gourd-shaped object.

"It's really black jade!" Fang Lingxin looked at the three little black stones, and her face was also full of shock.

She is from everyone's background, and she knows more about black jade, which is one of the more precious jade varieties, with delicate material, good light transmission effect, moist and bright, and natural and transparent. The overall elegance is like the vast Milky Way, natural freehand, smart and free. High-quality black jade is extremely rare and expensive, often costing hundreds of thousands or millions, comparable to diamonds.

Zhou Tian smiled bitterly: "This is not an ordinary black jade, but a kind of energy stone, so it is also called a black jade energy stone, it is an ore used by cultivators to arrange the cultivation of the spirit gathering array, in the cultivation world, they call it a black spirit stone, and the value is much higher than that of ordinary high-quality black jade." ”

Because of the relationship between cultivating Qi Ding Jue, Zhou Tian also consulted the information of jade. Jade is a natural spiritual object, high-quality jade contains a trace of aura, the higher the quality, the more aura it contains, and cultivators can absorb the aura in high-quality jade to cultivate.

It's just that even if it is a top-grade jade, the aura contained in it is extremely limited, and it still has some effect on cultivators in the early stage of qi gathering, and basically the effect of top-grade jade in the middle stage is not much.

Therefore, after reaching the middle stage of Qi Gathering, the mundane top-grade jade cannot meet the cultivation needs of cultivators, and at this time, the black jade energy stone is particularly important. The effect of using black jade energy stones to arrange the spirit gathering array is several times or even dozens of times the effect of the spirit gathering array arranged by the general best jade.

It's just that natural black jade gems are scarce in the world, they are even more valuable than diamonds, and they are very rarely circulated on the market. Originally, Zhou Tian was quite strange about this phenomenon, but now he finally understood that these surviving black jade energy stones had flowed into the hands of these people.

The ancients had a saying that "poor literature and rich martial arts", which is extremely correct, martial arts practitioners practice muscles and bones outside, and practice a breath inside, whether it is quenching or internal cultivation, they are inseparable from expensive medicinal materials, where can ordinary people afford to resist. This sentence was magnified several times more than when applied to the cultivators. For example, aside from the medicinal materials, let's just talk about the jade needed in the early stage of qi gathering, generally the amount of natural medium-grade jade that needs to be consumed in the first layer of qi gathering is about one piece every ten days, and the value of a piece of natural medium-grade jade rough is about 10,000 yuan, which is equivalent to about 1,000 yuan a day and 30,000 yuan a month.

When it comes to the second layer of Qi Gathering, the medium-grade jade can no longer meet the cultivation, and at this time, the aura in the high-grade jade must be needed to provide cultivation, and the same amount of one piece for ten days will cost about 100,000 yuan a piece, and 300,000 yuan a month.

When it comes to the third layer of Qi Gathering, it needs natural top-grade jade to meet cultivation, an equal amount of top-grade jade is often millions, and a month's cultivation needs millions or even tens of millions, which is what ordinary people can bear.

And these are just a calculation method, really when absorbing the aura in the jade to cultivate, but also according to the spiritual roots of different people to absorb jade with different attributes, such as the physique of the wood attribute, what needs to be absorbed when cultivating can only be the jade containing the aura of the wood attribute, this is not to say that you can find it if you want to, often the time and cost of finding jade with the same attribute are not much worse than the value of jade.

The black jade energy stone is a higher level than the Pu Neng jade, which has the effect of condensing energy, and the black jade energy stone can be used to lay a gathering spirit array in the cultivation place, and gather the spiritual energy between heaven and earth for their own use, which is the main cultivation method for cultivators after the middle stage of gathering qi.

However, because black jade energy stones are scarce in the world, and a piece of black jade energy stone cannot be used infinitely to arrange the Spirit Gathering Array, it is even more precious.

It was far away, and said that Fang Lingxin heard Zhou Tian say that the black jade energy stone was even more valuable than the high-grade black jade, and she couldn't help but be stunned. At the same time, it was the first time that she was curious about the inconspicuous strange things in these stalls, what kind of treasures were they all traded for black jade energy stones that were more expensive and rare than high-grade black jade?

However, she still remembered what Zhou Tian said before, just look at it and talk as little as possible, so she had to stay by Zhou Tian's side obediently and not speak.

The reason why Zhou Tian was able to find this place was because of his super powerful hacking skills, which was to find a trading market on the Internet that was impossible for ordinary people to store, called the Dao Cultivation Exchange, and it was also the only open cultivator trading place among the very few cultivator trading places in Tianjing, where the things traded here included low-level magic weapons, talismans, spirit grass, herb and wood liquids, as well as materials for refining magic tools and talismans, etc., and sometimes there were some semi-finished pills for sale.

Low-level talisman materials are easy to find, whether it is black dog blood, ordinary yellow table paper, aged cinnabar, and fox tail brushes are not difficult to find. But the main materials of the Qi Refining Pill he wanted to refine were not so easy to find, and they were definitely not something that could be found in ordinary herb halls.

The main spiritual grass of the Qi Refining Pill is the Silver Heart Grass, which is a kind of spiritual grass that is very similar to the dog's tail grass. Although the Silver Heart Grass is a low-level spirit grass, it is also extremely rare in this world where the spiritual energy is thin. It is not difficult to find other auxiliary materials for Qi Refining Pill, although they are also some precious herbs, which can be bought in some large Chinese medicine halls.

So this time he came to this Dao Cultivation Exchange, mainly for the Silver Heart Grass, and of course, the Medicine Furnace. Although he has Tianding in his body, Tianding's level is too high, and with his current cultivation, he can't even drive Tianding to one billionth.

Lao Jing told him that if he wants to learn alchemy, he must start from the most basic. As for refining the Qi Refining Pill, it is almost the same if there is a medicine furnace that is more than a hundred years old, of course, it would be better if you could get a low-level medicine tripod.

But he didn't know that the trading here was actually a black jade power stone, this thing...... He really didn't.

"Let's take a look first, maybe I'll pick up a leak by shit luck!" Zhou Tian said self-deprecatingly.

"How do you sell this?" Zhou Tian soon found something he was interested in, a brush that had fallen off.

He doesn't understand the trading code language here, and even if he understands it, he doesn't plan to do it according to their trading method, although the code language transaction seems very mysterious, but how tiring it is, people have a mouth in addition to kissing and eating, isn't it used to talk, hands have a more important role, if it is not a last resort, it should not be robbed of the work of the mouth.

But he was referring to a beautiful palace lamp hosta next to the brush, I don't know why, as soon as he saw this hosta that exuded a classical atmosphere, he felt that this hosta was very suitable for a person.
