All the items sold by the Qi Chamber of Commerce are either newly refined, or have erased the original owner's spiritual sense, so you only need to drip blood to recognize the master, and you don't have to worry about being eaten by the powerful spiritual consciousness inside.

"What the hell is this?"

After Li Ming refined the storage bag pinned to his waist, he found that there was nothing in it except for a hundred relatively muddy stones.

Hearing Li Ming's doubts, Zhu Rongrong said, "You take it out and I'll take a look!"

Li Ming's hand was on the storage bag, and as soon as his spiritual sense moved, a walnut-sized stone appeared in his hand......

"Spirit Stone! This is a low-grade spirit stone!" Zhu Rongrong said excitedly, "How many pieces are left in your storage bag?"

"Plus this one, a total of 100 pieces!" Li Ming replied.

"This Clan Chamber of Commerce is quite generous!No wonder there are so many unforgiving people in this world!" Zhu Rongrong said with emotion.

"This is the spirit stone?" Li Ming couldn't help but look back and forth, he knew the purpose of the spirit stone from the novel.

At the beginning of the division of heaven and earth, the clear qi rises, the turbid qi sinks, and the spiritual qi retrograde in the two qi of clear and turbidity, and then is absorbed by some earth's veins to form spiritual veins. The aura is transformed by the spirituality of all things in heaven and earth, and is absorbed by the leylines and mountains between heaven and earth, and attached to various mountains and rocks.

That is to say: the spirit stone is formed by the adsorption of spiritual energy by some stones; So, there will definitely be some impurities that cannot be absorbed. And these impurities have become the carrier of the attachment of the aura.

In the center of the spiritual vein, because the spiritual energy has been in a process of adsorption and release; Therefore, after the concentration of spiritual energy is high to a certain extent, because of the increase in density, the high pressure in the center of the spiritual vein is very strong and strong; At this time, the aura is compressed into a liquid state, which is: the spiritual vein.

The aura in the spiritual veins that was compressed into a liquid state was like being suppressed in the leylines or mountains, and became a pool of stagnant water; However, it affects the surrounding environment all the time, causing it to develop countless branches, just like groundwater.

These small branches, like groundwater, flow periodically under some places, and do not interact with the aura in the air to form a circulation, gradually forming a stable spiritual environment, which is commonly known as 'secret land', 'blessed land' and the like.

In the process of forming stagnant water in the early stage, as well as in the process of periodic flow later, some high-purity aura will precipitate out of the leyline's aura flow substance, forming a crystal-like, glassy luster or grease luster translucent substance, which is: spirit stone. The essence of the spirit stone is a collection of high concentration of spiritual power, but it will be wrapped in some impurities during the formation process.

Therefore, based on the amount of impurities contained in the spirit stone and the permeability of the spirit stone, the cultivator divided the spirit stone into four levels: lower, middle, upper, and extreme.

Among them, the next grade: the spirit stone with low transparency, which is lotus pink, bean green, light green, and milky yellow (the spirit stone has no spiritual power attributes, and the color is caused by the penetration of impurities), containing obvious defects in the form of cotton wool or sesame. This kind of spirit stone is mainly used in small formations or cheap mechanisms, teaching mechanisms, and is often mixed with demon beast Neidan.

Medium grade: spirit stone with slightly higher transparency, dark red, brown red, ochre red, duck egg green, sky blue, green seedling green, etc., with oil luster, no obvious flaws or fewer flaws to the naked eye. This type of spirit stone is often used for small and medium-sized formations, large mechanisms with fewer opportunities to be used, and alchemy furnaces to power up.

Upper grade: with glass luster, good brightness, usually only produced in the Wuyue mine, other mobile leylines have sporadic output. Most of them are white, milky white ice-like translucent crystals, which are flawless to the naked eye, and have also been produced with fish belly blue, light green, and moon white. This kind of spirit stone is generally used for the energy supply of large institutions such as Tiankun, the large formation pressure plate, and some insidious assassination and transformation magic weapons.

Excellent: The output is very small, and the existing few pieces are pure and transparent colorless crystals, with large volume and strong spiritual power. As an important energy reserve for large families and sects, they are generally not used easily.

At first, the exchange of lower-grade spirit stones and middle-grade spirit stones was only hundred-fold; However, when it was later discovered that there was a great shortage of high-grade spirit stones, they were changed to thousand-digit; It wasn't until I found out again that there was a priceless and unmarketed best spirit stone, which was changed to 10,000 miles.

The original discovery of the spirit stone was due to the movement of the earth's crust, which made the spirit stone at the junction of the spirit veins bare on the surface, and was discovered by family cultivators who went out to practice. After bringing it back to the family, it was found through research that the aura contained in these strange stones could be used for cultivation.

In the cultivation realm, there are many things that contain aura, but nothing else is like a spirit stone, except for aura and fixed impurities, there is nothing else. In those things, it's not that the aura in them is not strong, but that there are too many impurities in them, and unlike the fixed impurities in the spirit stones, they won't be absorbed by people; Therefore, these things can only be taken directly by monks after they have been refined.

Unlike spirit stones: the human body can directly absorb it, even faster and more efficiently than absorbing the spiritual energy in the air; This makes the monk lack spiritual power in his cultivation, and in the absence of any elixir, the spirit stone becomes the best choice.

As a result, there were spirit stone mines after that, and these spirit stone mines became the objects of competition among major families.

For the use of spirit stones, there are generally two ways: one is direct absorption, and the other is to gather spirits in array.

Direct absorption, which was discovered at the beginning. According to the grade of the spirit stone, the utilization rate of the aura is about: 70% of the lower grade, 80% of the middle grade, 90% of the upper grade, and the best grade is infinitely close to 100%.

Although the concentration of spiritual energy in the spirit stones is relatively high, it is slowly absorbed one by one; Therefore, even the best spirit stones will not explode. However, if anyone wants to be too anxious for quick success and quick profit, absorbing a large number of spirit stones at one time, the body explosion will definitely return.

Although the spirit stone can speed up the cultivation, it can only make the cultivation a little faster. Only in the environment, when the concentration of aura is low, the effect is more obvious.

For example, there is a cultivator with dual spiritual root qualifications and good understanding. If he was in a border area with a low concentration of aura, it would take about twenty years to build the foundation. If in this case, he has a steady supply of spirit stones, even if he only has low-grade spirit stones, the time to build the foundation can be reduced to ten to fifteen years.

Similarly, this cultivator, if he doesn't have a spirit stone, he may spend ten to fifteen years building a foundation in another place, such as the residence of a certain big family. If you directly absorb the spirit stones when cultivating, the time to build the foundation may be shortened to nine to twelve years.

Therefore, for the cultivators of the small sects, the function of the spirit stone is: to reduce the gap with the cultivators of the big clans.

As for the cultivators of the major sects, the spiritual energy content in the spirit stones has accelerated their cultivation to a certain extent, but when the grade of the spirit stones is not high, the effect is not great!

That is to say, there are several uses for direct absorption:

First, it is used by people with few resources, such as outer disciples, small sect disciples, and small family disciples, and those who are in an environment with a low concentration of aura. Because, under normal circumstances, the spirit stones they earn are one by one, and they are basically absorbed directly when they get their hands.

The second is the disciples of the big family and the big sect, they have the opportunity to come into contact with high-level spirit stones, but the amount is also not much, so it is generally not enough to set up a formation, so they can only choose to absorb it directly.

The third is that when the situation is urgent, the time is not enough for you to set up a formation, and it will be directly absorbed. However, this kind of absorption is not as fast as the elixir to replenish the spiritual energy in the body, it is about the same as the usual cultivation speed with the spirit stone, and it has no side effects compared to the elixir. Therefore, in the case, due to the emergency situation, I had to choose to directly absorb the spiritual energy in the spirit stone to replenish the spiritual power in the body.

And then there is: the Gathering Spirit Array.

This method has a higher utilization rate and longer duration for the aura in the spirit stone, but it has certain limitations.

First of all, the amount of spirit stones should be enough to set up a formation; Secondly, there is a place for you to set up a formation; Third, there is time for you to set up a formation; Fourth, after setting up the formation, you can cultivate quietly and undisturbed.

Therefore, under normal circumstances, the cultivation of the Gathering Spirit Array is used during retreat.

Although, you can use the spirit stones to press into a formation plate, put out some advanced spirit gathering formations, extract the spiritual power in the spirit stones and spread it in the air, forming a high spiritual power environment to improve the cultivation efficiency; However, due to the urgent demand for spirit stones in some fields, especially the development of sand tables and the systematization of alchemy, the use of this spirit stone has not been popularized on a large scale, and it can even be said that it is unknown. In addition, even some big factions of formations, when using spirit stones to suppress the formation disk, there are also injuries caused by spirit stones bursting; Therefore, even if you are tempted, but because you don't have the technology, you can only give up this more efficient array after the temptation is due to its side effects.

Some people also wondered: Why didn't those who discovered the spirit stone mine hide in it and secretly cultivate, but instead tell a certain big family?

This is because the concentration of spiritual energy in the spiritual stone mine is particularly high.

In the spirit stone mine, there is everywhere the spiritual energy that has gathered in the air after overflowing from the spirit stone. Although there is only a small part of the aura that each spirit stone emits from it, it can also form a high-concentration aura environment locally when gathered.

How thick is the aura at this time?

It's the kind of thing where if you don't run the exercises to absorb the aura, the aura will drill into your body by itself.

When the amount of spiritual energy penetrating into the body is greater than the amount that the monk transforms after running the exercises, that part of the untransformed spiritual energy will run around in the body, destroying the meridians, causing the monk to explode directly.

Generally, in this kind of environment, there are only two kinds of people who will not die: one is super power, which absorbs a huge amount of aura per unit of time, so much that it is unimaginable; The second is those amazing and glamorous sons of the sky, who often not only do not explode, but may also be washed away by the I Ching.
