Mortals use gold and silver as the equivalent, while cultivators use spiritual stones as the basis of exchange.
Magical weapons, spiritual energy, even magic weapons, skills, and genius treasures are all that cannot be purchased with spiritual stones.
Spiritual stones as the basis of exchange are different for immortal cultivators than gold and silver are for mortals. The difference is that for immortal cultivators, spiritual stones can be used to improve cultivation, restore spiritual power, and control formations.
Law and other places.
For immortal cultivators, spiritual stones, in addition to exchange, also play the role of food and water for mortals. There is an old saying: "Food is the most important thing for the people." This sentence is equally applicable to immortal cultivators and spiritual stones.
Even outliers like Yin Xiuxuan often need spiritual stones.
The importance of spiritual stones to immortal cultivators is well understood by every immortal cultivator.
Just like immortal cultivators are divided into various levels, spiritual stones also have their own grades, but they are much simpler than those of immortal cultivators.
The most common spiritual stone, which is the level of spiritual stone commonly used by low-level monks like Yin Xiuxuan, is called "lower grade spiritual stone". On top of the "lower grade spiritual stone" there is a spiritual stone that contains a hundred times more spiritual energy and a hundred times more purity, called "lower grade spiritual stone"
"Middle-grade spiritual stone". Above the "medium-grade spiritual stone" there is the so-called "high-grade spiritual stone" that is a hundred times more powerful.
From "Mengxi Bi Tan", Yin Xiuxuan read about the exchange method of these spiritual stones.
Generally speaking, in terms of the amount of spiritual energy, a middle-grade spiritual stone is a hundred times that of a low-grade spiritual stone, and a high-grade spiritual stone is a hundred times that of a middle-grade spiritual stone. They should be exchanged for a hundred times the price.
However, the purity of spiritual energy and the difficulty of collecting high-grade spiritual stones make this exchange more than just that. Generally speaking, one medium-grade spiritual stone can be exchanged for one hundred and ten low-grade spiritual stones, and one high-grade spiritual stone can be exchanged for
One hundred and ten pieces of medium-grade spiritual stones.
Even this kind of exchange is only in terms of price in the world of immortality. In fact, most people who have middle-grade spiritual stones are not willing to exchange them, so the price can be raised to about 120 yuan. And with
A person with a high-grade spiritual stone is at least a being that makes Yin Xiuxuan call him heaven. How could such a being care about a small amount of low-grade spiritual stone.
In this way, low-grade spiritual stones are most commonly used in the market, medium-grade spiritual stones are rare, and high-grade spiritual stones are impossible to appear in the circles that Yin Xiuxuan may come into contact with now.
Seeing this, a question arises. Is there a higher-level existence than high-grade spiritual stones?
The answer is not given in "Mengxi Bi Tan", after all, the author's level is not too high.
Regarding this question, Yin Xiuxuan had also thought about it. He personally felt that the answer was yes, but he immediately put the question aside. Even if it existed, what did it have to do with him.
Unexpectedly, this question suddenly echoed in his mind again.
Looking at the half-cut spiritual stone in front of him, Yin Xiuxuan said to himself with a serious face: "Middle grade? Top grade?"
"Buzz...buzz..." The wire wasp screamed and moved towards the opening cut by the dagger, seeming to want to get in. It was its cry that called Yin Xiuxuan back.
"Let's take a look again!" Putting his hand on the surface of the spirit stone, Yin Xiuxuan once again let his thoughts enter the spirit stone and sensed it.
After a moment, an excited and slightly disappointed smile appeared on his face, "After all, it is impossible to have such good luck! But the middle-grade spiritual stone is not bad!"
It turned out that when Yin Xiuxuan first put his mind into the spirit stone, he suddenly sensed the pure and abundant spiritual energy in it, which scared him out. After reading "Mengxi Bi Tan", he was really sure that it was not a low-grade stone.
The spiritual energy possessed by spiritual stones.
However, in his hurry, Yin Xiuxuan just stopped at the touch of a button and did not check it carefully, so he did not know what grade the spiritual stone in it was, which was why he had his initial doubts.
After visiting it again, Yin Xiuxuan finally confirmed that there was a middle-grade wooden spirit stone inside, not the high-grade spiritual stone he had boldly guessed.
Yin Xiuxuan also took a look at the spiritual stone inside. It was almost the size of a standard spiritual stone, but the purity of the spiritual energy in it really shocked Yin Xiuxuan.
The purity of the pure energy he could sense was higher than the true energy in his own body. When he thought that the accumulated true energy contained in countless low-grade spiritual stones of the same level in his body was not as good as the level of this mid-grade spiritual stone, Yin Xiuxuan
This was when surprise turned to joy.
"Good stuff, really good stuff!" Yin Xiuxuan said with a slight smile as he patted the huge spiritual stone in front of him.
"Buzz...buzz..."
"You are also a good treasure!" Yin Xiuxuan called the iron wire back with his mind, casually put half a piece of spiritual stone into the bamboo tube, and then put it in it.
If it were an ordinary low-grade spirit stone, there were so many in this mine, and Yin Xiuxuan would not begrudge it, but this middle-grade spirit stone was something that even the foundation-building monks would snatch, so he would not hand it over generously.
Wire wasps "spoiled".
"High-level spiritual stones can be used when clearing levels to increase the chance of clearing levels! They can also arrange formations to exert greater power, and they can be used in many ways such as making magic weapons!"
Thinking about the use of this middle-grade spiritual stone, Yin Xiuxuan was just a casual cultivator for two months. Now he is just a peripheral disciple. He is not the kind of disciple of the foolish and loyal sect. He has such a good thing and offers it to the sect.
If you can get one or two rewards, how can you get such a middle-grade spiritual stone?
After all, this high-level spiritual stone has too many uses for low-level monks, especially key uses.
"How can we take this out!" A new question appeared in front of Yin Xiuxuan. The spirit stones in the spirit stone mine couldn't be taken away by him at all, unless...
"Okay! Let's do it!" Yin Xiuxuan clapped his palms together and made his decision. He turned back and looked at the huge spiritual stone lying quietly on the ground.
…
Ten days later, at the entrance of the Lingshi Mine, a figure emerged from inside.
"Who!" the guarding disciple shouted.
"I am a disciple who has entered mining!" The visitor showed his identity token, and it was undoubtedly Yin Xiuxuan.
The guarding disciple in green came over, looked at Yin Xiuxuan, frowned, and said, "Why did you come out in so many days? Have you collected everything?"
Yin Xiuxuan patted the dust on his body and raised a puff of smoke. He covered his mouth and nose and said, "Brother, I emptied a mine and couldn't find any other useful mines, so I came out."
"Oh! A mine has been mined out. Which one are you talking about? Mark it out for me!" As he said this, the Tsing Yi disciple's expression immediately improved and he quickly handed the jade slip to Yin Xiuxuan.
When Yin Xiuxuan read the jade slip, he saw that it was indeed different from the mark he was holding. In the area where he was, only the hole where he guessed the spirit stone showed that there was a spirit stone, and there were no spirit stones in the other near white strips.
Saying "How cruel" to himself, Yin Xiuxuan smiled and marked out the mine where he mined.
"Oh, that's right, there really isn't much ore left there! Very good, another mine has been solved, so I can leave this hellish place as soon as possible!" The Tsing Yi disciple laughed heartily as he spoke.
