The spirit stone, the crystallization of the aura of heaven and earth, contains abundant aura!

As we all know, aura is a thing that monks rely on to cultivate and swallow, and it can even be said that everything that cultivates the truth and seeks the Tao is based on aura.

According to the quality, the spirit stone is divided into four grades, the lower grade, the middle grade, the upper grade and the legendary best.

Originally, Lin Chen thought that the reason why there was a division of quality was because the amount of spiritual energy contained in different quality spirit stones was different.

But later he found out that this was not the case.

And through observation, Lin Chen found that the quality of the spirit stone seemed to be linked to the realm of monks.

For example, a cultivator in the Qi refining period will only use lower-grade spirit stones to trade or cultivate, and if a large amount of transactions is involved, they will use artificial spirit stone equivalents to trade, such as the Qingyun Spirit Leaf of the Qingyun Sect, the Corpse Spirit Pill of the Ten Thousand Corpse Gate, the Bihai Spirit Bead of the East China Sea Scattered Cultivation Alliance, and so on.

When it comes to the foundation building period, monks generally use medium-grade spirit stones for trading and cultivation, and occasionally use low-grade spirit stones.

Although in the market, the two are in a hundred base, but only when they reach the corresponding realm, can they be exchanged for spirit stones of the corresponding quality in the market.

And the use of spirit stones of different qualities by monks in different realms seems to have formed a common custom in this world!

"There must be a reason behind the formation of customs, to integrate the medium-grade spirit stone into the gas refining market, so as to facilitate the operation of the transaction, I believe that no one will think of it, but after all, it has not been ......."

"Is it the scarcity of the number of medium-grade spirit stones, no, unlikely, maybe the number is indeed small, but it is not cherished to this extent, otherwise, the exchange ratio will not be one to one hundred......"

Lin Chen pondered.

"Spirit stones are not only used for trading, but also for cultivation, and medium-grade spirit stones are not used in the market of the Qi Refining Period, I'm afraid it's not that they don't want to use it, but for most Qi Refining Stage cultivators, the spiritual energy in the body of this kind of spirit stone can't be used......"

As soon as he thought of this, Lin Chen looked at the medium-grade spirit stone on the experimental table.

It is a milky white jade, the size of a teacup, exuding a slight white light, and there is a faint warmth in the hand, which is different from the ordinary jade-like lower grade spirit stone, there is an indescribable strangeness.

Lin Chen mobilized the true qi in his body and wanted to attract a part of the spiritual qi in the spirit stone into his body, but he found that this kind of operation was like lifting a boulder, which was very difficult.

"Sure enough, just like in the previous life, primitive barbarians could only use flames, while modern people can use electrical and nuclear energy, different levels of energy, do they need different realms?"

Lin Chen was thoughtful.

With the in-depth research over the years, Lin Chen gradually discovered that this world composed of spiritual energy not only has a gap in the realm of cultivation itself, but also a difference in the level of everything.

As a result, the heavenly and earthly treasures that can only be used by monks of different realms are divided.

If you use it beyond the boundary, unless it is specially treated, it will waste most of the utility at least, and it may explode and die at worst!

And Lin Chen guessed that maybe for mortals and low-level monks, the world is the same, but for high-level monks, the world they see is probably different.

For example, strange things such as the morning glow purple qi and the Taiyin moonlight are just ordinary sunrise moonlight for mortals and qi refining period monks, but for foundation building period monks, it is the moonlight full of the sky and the purple qi coming from the east.

And the reason for all these differences, Lin Chen felt that it should be the aura of this world, and like the particles in the previous life, there was a division of energy levels!

The difference in the different energy levels of the aura has created the difference in the nature of this world!

"Of course, all of this is just speculation, I can't be sure if it's because the Qi Refining Cultivator has difficulty mobilizing the Medium Grade Spirit Stone Spiritual Qi because there is an energy level, or because of some other reason. So we have to experiment......"

"However, I can first assume its existence, and then use the existing phenomenon to falsify, if there is no problem, then it means that there is indeed an energy level in Reiki."

"However, according to the available information, the monk has the division of realms such as [Qi Refining], [Foundation Building], and [Jindan], and it is impossible not only to change the state of the spiritual energy that has been refined in the body from a gaseous state to a solid state, but also involves qualitative improvement......

"This may prove that there is an energy level for Reiki, and maybe I can start from this aspect......"

"As long as I control the mystery of the monk's promotion, I can verify whether the aura of this world has an energy level......

Lin Chen pondered for a while, then picked up the [Spirit Condensation Liquid] purchased from Yunlaifang City.

[Spirit Condensation Liquid], which can promote the liquefaction of true qi in the monk's body, is one of the three treasures in the foundation building period.

However, Lin Chen found that simply liquefiing the spiritual energy only formed the spiritual liquid, and could not improve the energy level.

"So, do you need an introduction, or a catalyst?"

Thinking of this, Lin Chen pressed his hand on the table, and suddenly, the formation of the entire laboratory was immediately activated!

The prohibition of dragon flying and phoenix dancing emitted a brilliant spiritual light, and under the traction of the formation, a large number of low-grade spirit stones swarmed out of the aura around it, forming a vortex of spiritual energy directly in the room!

This is based on the idea of the cyclone realm during the Qi refining period, and the aura is rotated to assist in liquefaction.

Lin Chen took out a [Spirit Condensation Liquid] and threw it into the Spirit Qi Vortex without hesitation.

This scene is enough to make the scattered cultivators crazy, for them, the foundation building spirit objects that they may not be able to get by working hard are just thrown and wasted!

But for Lin Chen, these so-called foundation-building spiritual objects are just auxiliaries, and the evolution of the essence of life has to rely on itself.

If you can't even have a clear understanding of the direction of your own evolution, and just rely on the elixir spirit to forcibly break through, what is the difference between it and a barbarian who has no power but no brains?

You must know that what he is seeking is the Great Dao of the world, and what he is asking for is an immortal true immortal, not to become a monk who can break through as long as there are enough elixirs and spiritual things!

After the [Spirit Condensation Liquid] came into contact with the Spiritual Qi Vortex, it directly collapsed and dispersed, forming a milky white aura that emitted a faint glimmer in Lin Chen's [Spirit Viewing Array].

It swam in a pale white aura, and then began to dim a little.

"Huh?" Lin Chen frowned.

The liquefaction of the aura has already begun, but the high-level aura obtained from the [Spirit Condensation] seems to be degrading!

"Not enough? No, no, it's not a matter of quantity, it's that there is no energy level jump at all. Lin Chen glanced at the medium-grade spirit stone on the side, and with a wave of his big hand, a part of the spiritual energy in his body poured into the formation.

But even so, the aura in the formation still didn't have any energy level jump!

'The aura of the medium-grade spirit stone originally tended to be stable, but under the influence of the aura of the lower-grade spirit stone, it began to slowly degrade, and it seems that the decline in the aura energy level is even easier to occur than imagined......

Moreover, it is not only easier for the energy level of the Reiki to decrease than to increase, but also to go from active to inert, and although the two can be converted to each other, the difficulty faced is different......

'But it's normal to think about it, the aura is to form everything and thus serve as the foundation of the world, and it is definitely several times easier to transform from active to inert with the decline of energy levels than its reverse ascension......

This characteristic of aura couldn't help but remind Lin Chen of the theory of entropy increase and entropy decrease in his previous life.

Of course, these are not the key now, the key is that I refer to the environment of the breakthrough during the foundation building period, but why has there not been any jump in the aura energy level until now? ’

"Or ...... My guess was wrong, Reiki doesn't have energy levels, but has other properties? ”

Seeing the milky white aura in the [Spirit Viewing Array] that exuded a glimmer of light dimmed little by little, Lin Chen frowned deeply.

What went wrong......

Suddenly, Lin Chen realized one thing, the breakthrough in the foundation building period, as far as he knew, it seemed that this only happened among cultivators!

And all cultivators, whether it is human immortal cultivation, demon beast bloodline atavism, or those strange creatures cultivation, they all have one thing in common, that is, they have self-awareness and wisdom!

After all, Lin Chen had never heard of a stone or a dead thing that could complete the evolution of his own life essence!

"Therefore, the breakthrough in the foundation building period, or the jump in the aura energy level, also needs the ...... of the living beings themselves Consciousness, or wisdom? ”

"So, do you still want to conduct a monk experiment?"

Under the bright light, Lin Chen sighed softly, but his eyes became deeper and deeper.
