In the spacious practice room, Liu Yu sat quietly cross-legged.

A rich cyan aura appeared on the masculine face, and the Nascent Soul spiritual pressure filled the room wantonly.

Within the body, the tenth level of Qingyang Gong is constantly operating, refining the medicinal effects and massive spiritual power emitted by Bi Ganoderma.

First, through seventy-two cycles of the physical body, the spiritual power is initially refined into mana, and then through thirty-six cycles of the Nascent Soul state, it is refined into real Nascent Soul mana.

Different realms have different requirements for the "purity" of mana, and the intensity of mana is also very different.

Therefore, as the realm improves, the number of cycles of the Great Circular of the Kung Fu will also gradually increase.

It is necessary to further eliminate the "impurities" in the spiritual power and mana during the operation of the exercise again and again, and further condense the mana.

If we talk about the Qi Refining Realm, the purity of mana essence is generally 90%, then in the Foundation Establishment Realm, it is over 95%.

The golden elixir realm is at least ninety-nine percent, and can reach as high as ninety-nine point ninety-nine.

When it reaches 99.99%, if the Golden elixir cultivator wants to further purify his magic power, it is no longer possible to rely on himself alone. He must rely on external forces, such as spiritual objects or heavenly materials and earthly treasures, etc.

As for the realm of Yuanying, through the great cycle of the Yuanying state, it can be easily purified to ten digits after the decimal point.

Compared with the Jindan realm, there is a qualitative change.

From gaseous mana to liquid mana, and then to solid mana in the golden elixir realm, there will be a qualitative change with each transformation, and the "mana intensity" that can largely represent power increases significantly.

For the same unit of mana, the power of solid mana can even exceed that of liquid mana by dozens or hundreds of times!

In the same way, the power of the Nascent Soul's mana purified by the Nascent Soul is dozens of times greater than the power of the Golden Elixir.

Of course, the specific difference will still vary from person to person, but for the same unit of mana, the power of different realms will differ by at least ten times, and can be close to a hundred times at most.

For example, the peak of the golden elixir is compared to the early stage of foundation building.

Therefore, between every major realm, there is an almost insurmountable chasm!

Throughout the history of the world of immortality, there are very few people who can defeat the superior without the help of external force.

Within Liu Yu's body, the massive amount of spiritual power released by Bi Ganoderma rapidly circulated through the heavens again and again, imprinted with divine consciousness and refined into wisps of extremely small dark cyan mana.

Although the amount and scale of spiritual power can be seen with the naked eye, its power has increased hundreds and thousands of times after being refined into Nascent Soul mana.

During the whole process, the spiritual power actually did not really decrease much, it was just compressed and condensed into higher quality Nascent Soul mana, which seemed to be reduced in size many times.

The orderly flow and operation of spiritual energy according to certain rules is called "spiritual power". The two are essentially the same thing.

The main purpose of the Great Zhoutian Cycle is to eliminate impurities in the spiritual energy as much as possible.

Let it change from disorder to order, then continue to compress and condense it to meet the requirements of the corresponding realm, and finally be branded with divine consciousness.

To a certain extent, mana can also be called spiritual power.

Liu Yu sat cross-legged, the green spiritual light on his face constantly changing, bright and dark, and his spiritual pressure also rose and fell.

In Dantian, the chubby blue Nascent Soul is making secrets with its hands, and its whole body is shining with soft blue light.

Wisps of dark blue mana, like beautiful ribbons, floated rapidly from all the meridians and merged into the six-inch Nascent Soul, completing the final thirty-six cycles.

If your spiritual consciousness is strong enough, you will find that the cyan ribbon is not a real "ribbon", but is made up of cyan crystals that are smaller than dust.

Compared with the golden elixir realm, the volume of solid mana is once again reduced by about ten times, but each unit contains more spiritual power, and the mana intensity has also increased significantly.

Below Nascent Soul, the vast sea of ​​mana is made up of countless tiny crystals!

After thirty-six Nascent Soul cycles, "crystals" that were almost invisible to the naked eye slowly floated down to the sea of ​​mana below.

However, this is just a drop in the bucket.

Liu Yu glanced over with his spiritual consciousness and could barely see the level of the sea of ​​mana rising.

During the process, the growth of Nascent Soul is also very small. If you don't experience it personally, you won't be able to tell the difference with your spiritual consciousness.

As time passed, the massive spiritual energy released by Bilingzhi gradually decreased, and was completely refined in less than three hours.

"Huh~"

Slowly withdrawing his power, Liu Yu opened his eyes and exhaled heavily.

"It is indeed much faster than meditating to refine qi, but it is still far inferior to the elixir."

Feeling the extent of his cultivation, he couldn't help but shake his head slightly.

"Taking Ganoderma lucidum directly will only have a little more than 10% of the effect of a fourth-grade low-grade elixir."

"And compared to elixirs, elixirs contain more impurities, and it takes some time to remove them afterwards."

"Generally speaking, elixirs are still the best choice. Taking elixirs directly is not a long-term solution."

After finishing his work and standing up, Liu Yu silently concluded.

Spiritual medicines often have more than one "effect" or "characteristic". Except for the massive amount of spiritual energy and the effect that can improve cultivation, other effects are completely burdensome to monks.

This "burden" can also be regarded as "impurities".

After the elixir is refined, it still remains in the monk's body and continues to exert corresponding effects.

These medicinal effects must take time to be eliminated, otherwise they will be extremely detrimental to cultivation in the long run.

The reason why Liu Yu chose "Blue Ganoderma" was because in addition to its efficacy in improving cultivation, this drug has the least other medicinal effects and can save a lot of time in post-treatment.

The elixir directly absorbs the spiritual energy between heaven and earth to grow, and each unit of heaven and earth spiritual energy itself contains some impurities.

Qi refining and foundation building are at a low level, and the requirements for the purity of mana essence are not that high, so there won't be much trouble in the future, so there is no need to worry about this.

However, the realm of Jindan Yuanying requires extremely high purity of mana essence, and these impurities must be removed.

Compared with taking it directly, the method of refining it into elixirs is much superior.

In the process of refining the spiritual herbs into elixirs, the excess medicinal effects have been eliminated, leaving only the corresponding useful medicinal effects.

Most of the impurities in the spiritual power will also be removed, greatly saving the monks' refining time.

Moreover, the combination of the medicinal effects of many spiritual herbs and elixirs can also amplify the cultivation-improving properties of the main medicine, making the elixirs far more effective than elixirs.

However, whether elixirs or elixirs contain certain impurities, it is best not to take them continuously.

If impurities are not removed in time and accumulate to a certain extent, they may even become an obstacle to improvement in cultivation.

Although after condensing Nascent Soul, he was able to get rid of the influence of erysipelas, Liu Yu still had to pay attention to this aspect.

"The civilization of cultivating immortals has been developing for a million years or more. It is not unreasonable for the method of directly taking elixirs to be gradually eliminated~"

Liu Yu thought silently.

During this time, he had a deep understanding of the advantages and disadvantages of taking elixirs directly.

All kinds of thoughts passed away in a flash, and Liu Yu closed her eyes again.

In Dantian, the baby-fat cyan Yuanying moved and picked up the sunset golden rainbow gun floating in the lake of mana.

Immediately, he spit out a small mouthful of Yuanying's origin, landed it on the dark golden spear, and began to warm and nourish the treasure.

In this way, Liu Yu ushered in a brief period of peace, and his cultivation steadily improved at a speed far exceeding that of other True Lords.

Every few days, I take Ganoderma lucidum to practice, and then warm up the sunset golden rainbow spear, Jiugong Qingyang lantern, purple electric cloak, Youxia armor, red flame shield and other magic weapons one by one.

Maybe Tianfeng has already completed the mission, maybe it's because Liu Yu has just been promoted, maybe it's because the human-monster war has been going on so far, and the intensity has gradually decreased.

In short, the Seven-Nation Alliance has no intention of issuing orders for the time being.

Three years pass by in a blink of an eye while cultivating peacefully.

…

Three years later.

Tongtian Peak Cave Mansion, practice room.

"Huh~"

After finishing the practice, Liu Yu felt the surging magic power in his Dantian and raised the corner of his mouth with a slight smile.

Although the level of improvement in cultivation level is very small every time he practices, it is still very impressive after three years.

If the Nascent Soul realm is also divided into nine levels like the Qi refining realm, then his cultivation at this time is already a real "Nascent Soul second level"!

After all, strictly speaking, Liu Yu is not really a new Yuanying.

When conceiving a baby, taking "Yingnuo Dan", one of the three treasures of conceiving a baby, will directly increase the cultivation level of the Nascent Soul by fifty years, and in fact, it will have already left the state of the newly promoted Nascent Soul.

Coupled with the secret method of childbirth and the strong foundation of the previous realm, the speed of cultivation improvement itself is far faster than that of other True Lords, so it is not surprising that the cultivation level has progressed smoothly.

"very good."

"In this way, we will have greater confidence in this trip."

After finishing his work and standing up, Liu Yu's eyes flashed with a faint light.

If protecting True Lord Mo Mei this time went smoothly from beginning to end, he would naturally not think too much about it.

I also had some bold idea, just get the "Flying Immortal Pill" prescription safely.

But if an accident occurs, your strength will be put to use, and you may be able to gain more.

Chaos is the ladder up.
