The remote bunker, with the arrival of Li Boyang and the others, gradually had a glimmer of life.

The three of them practiced for the first time, and they should bring the same things.

Marching Rations, Compressed Water, Water Collectors, Mushroom Strains, Dila Crystal Purification Module, Artificial Sunlight Emitter, ...... Although it takes a week for the strains to grow, and the amount of marching food and compressed water is very limited, everyone has to live a hard life for the time being

However, the appearance of the Dilla crystal purification module still gave everyone hope, even if they were full and hungry, they still gritted their teeth and persevered.

The bunker was originally a sentry post, but it was expanded into a bunker due to the discovery of miniature crystal veins underground.

Even so, the underground is still limited in size and cramped space.

The food and water that I originally ate were also divided from the Black Iron Battle Castle.

The Black Iron Battle Fort is gone, and it is not easy for the bunker to hold out for so long without being completely ashed.

Where else can I think of a purification module to purify meat, soil, and fungus.

It's just a dream, and you can only wait for death.

Now he is not dead, but has ushered in an unexpected new life, and everyone is already satisfied, how dare they ask for more.

Everyone in the bunker didn't want to, but Li Boyang had to think about it.

After all, the three of them just stayed here for a while, and they still had to leave after all.

If Li Boyang and the three of them leave, without them hunting the creatures of the demon cave to use as nourishment, the energy in the Dilla crystal will run out and they will not be able to get charged, what will they do?

To put it bluntly, the people in the bunker don't have the strength to continue living.

If you don't have power, you can't hunt cave creatures.

If you can't hunt cave creatures, you won't be able to recharge the Dilla Crystal.

The Dilla Crystal cannot be charged, and the people in the bunker will eventually have to wait for death.

Everything seems to be back to square one.

After thinking about it, Li Boyang still created a batch of [Yuan Neng Purifiers] that could not be simplified anymore.

The crystal is used as the container, the bacteria are used as the purification core of the container, and then the crystal nucleus of the demon cave creatures is used as the original kinetic energy, supplemented by the bone marrow of the demon cave creatures as a buffer.

The highest is then injected into the mental force framework to promote the operation of internal energy.

One by one, the [Yuan Energy Purifier] that was so rough that it couldn't be rougher was created like this.

The heavy task of teaching everyone "Quanyou Basic Form", Li Boyang lost it to Kaisheng.

The task of hunting was given to Romy.

On the other hand, he gave two high-quality [Yuan Neng Purifiers] that had been made a long time ago to the two.

"Touching the Yuan and Cultivating the Body Detailed" was written into a book, Li Boyang was too lazy to teach people, and directly let Kaisheng and Romi learn by themselves, if there is anything they don't understand, ask again.

I don't know if it's because of the stimulation, Kai Sheng and Romy's cultivation speed for Yuan Neng is a little unexpectedly fast.

At first, Li Boyang didn't care too much and didn't care too much.

But later, he gradually felt that something was wrong, Kai Sheng's extraction speed of their Yuan Energy seemed to be a little wrong, and they all caught up with half of his [Touching Yuan Cultivation] stage.

Only then did he turn his attention away from the next step of studying Yuan Energy, and instead focused on the [Pure Crystal].

After all possibilities were ruled out, all that was left was the difference in the environment - that is, the Clear Crystal Vein below.

The output of [Clear Crystal] in the Demon Cave is not small, but because of the difficulty of mining, the veins are small, and there are many fragile products, resulting in a high price.

None of the [Clear Crystals] that can be brought to the watch world are cheap.

In the eyes of the Ministry of Science and Technology, the appearance of the [Clear Crystal] is the opposite of the object after the flesh and soil of the demon cave devours the surrounding energy and substances too cleanly.

Naturally, there is a very strong rejection reaction to the breath of the demon cave.

In Li Boyang's understanding, the [Clear Crystal] is more like the uneaten food spit out of the flesh and soil of the Demon Cave, or the forbidden [Vacuum].

The flesh and soil of the Demon Cave devour energy and matter, constantly splitting and multiplying, and the things that can be left behind are not only [vacuum].

Because of the vacuum, the Crystal is strong and fragile.

The solidity is because of the substance that makes up the [Clear Crystal], the flesh and soil of the demon cave cannot be swallowed at all, and can only be spit out.

The fragility is due to the vacuum nature of the [Clear Crystal], once it encounters a high concentration of demon cave pollution aura, it is easy to cause inconsistencies in internal and external pressures, and then collapse and shatter.

Because of this characteristic, [Clear Crystal] is often used to detect deep transformation or pollution of the human body.

[Clear Crystal] vacuum rejection seems to have nothing to do with Yuan Neng.

But if you think about it at a deeper level...... What if the vacuum is not empty?

The [Yuan Energy Vortex] in Li Boyang's body was running endlessly all the time, trying to interact with some higher-level order energy every second...... But because the gap between them is too big, every interaction is actually a failure, and what is finally absorbed by the [Yuan Energy Vortex] is actually the overflowing particles of that energy.

[Crystal Clear] is special because of its appearance crystal, which causes it to seem to reject all energy.

In fact, due to the nature of the vacuum, the Crystal has always had an astringent effect on certain energies.

For example, Yuan Neng!

When he found out about this, Li Boyang was a little confused.

If this is the case, [Pure Crystal] may be changed to another name from now on, such as Primitive Stone, Primordial Crystal, and so on.

When cultivating, you only need to put a circle around you to increase the speed of obtaining Yuan Energy by several times.

When the [vacuum] is filled with meta energy, it may be possible to channel it out to replenish the meta energy consumption, and then use it again.

In an instant, it has changed from a high-end object dedicated to detecting pollution to a necessary resource for cultivation, and the price will soar tenfold and hundredfold.

Unless the Ministry of Science and Technology can research the [Artificial Clear Crystal], I'm afraid something big will happen.

Li Boyang hesitated for a long time, but finally didn't tell Kaisheng and Luo Miming about it.

Let's just let the two of them think they're talented.

After figuring out the true use of [Clear Crystal], Li Boyang couldn't help but think deeply.

Once the vortex of Yuan Energy is formed, the absorption of Yuan Energy will no longer stop, and everyone is like this, at most the efficiency (talent) of absorption is different.

In other words, even if it is slowly sharpened by time, it can be rubbed to the consummation of the Yuan Energy in the Yuan Energy Vortex in about fifty years.

So...... What's next? How can we safely connect our own energy with external energy?

First of all, you have to avoid the pollution of the Lusheng Realm, and secondly, you have to have the strength to resist the sixth order, otherwise this exterior scene will be meaningless.

The first thing that Li Boyang thought of was - magic weapon.

The essence of the [Yuan Energy Purifier] is actually [Wai Dan], which is originally intended to be used to purify and purify the Yuan Energy and assist in cultivation.

So can you create a [magic weapon] like this, use the [magic weapon] to contact the external energy, and then manipulate the external energy, and finally reach the [exterior] realm?

And the biggest problem in creating the [magic weapon] is nothing else, it is precisely how can one's own yuan energy stay in the [magic weapon] for a long time?

If you can't retain your own energy for a long time, even if you create a [magic weapon], eventually the [magic weapon] will be completely polluted by the energy of the outside world, and then go out of control.

This kind of [magic weapon] is meaningless, because it does not belong to oneself and will get out of control at any time.

From the point of view of the Immortal Dao, this is that the [magic weapon] has not been refined.

But what if you add [Pure Crystal]?

Li Boyang was stunned for a long time, and finally came to the conclusion that it seemed to be ...... Feasible.

After coming up with this answer, Li Boyang's attention shifted from the [Clear Crystal] back to himself.

The core problem of [magic weapon] has been solved, but there is a problem with his current Yuan Energy.

The upper limit of the Yuan Energy Vortex has undergone drastic changes due to the changes in his mind and thoughts, and even the Yuan Energy itself has undergone a slight qualitative change.

In Li Boyang's perception, the original colorless, formless, mist-like Yuan Energy had changed into a pale golden liquid state at this time, converging in the middle of the Yuan Energy Vortex.

The liquid elemental energy was steaming with mist elemental energy, but it seemed to be contaminated by this gold, and gradually changed into a faint gold.

This made Li Boyang puzzled at the same time, but also very puzzled, could it be that Yuan Neng really had the attribute of idealism?

Whether the world is idealistic or materialistic, he has no interest in knowing at all.

Because the question is too far away for him.

Even in the last life, the people who were able to touch on this kind of problem were either great scientists or great philosophers.

But he never thought that on the issue of Yuan Energy Ascension, he would encounter a problem that he had never thought of.

The change of the mind will reflect the change of energy, and then make the energy undergo a qualitative change at a certain level.

For the first time, the mind and the Yuan Energy were connected in an unbelievable way.

Just when Li Boyang was puzzled, the [system] that had been silent suddenly reacted and passed a message to him.

Li Boyang couldn't help but be stunned after reading the information, and his expression when he looked at the system panel suddenly became a little strange.

Is this seemingly rudimentary synthesis system still responsible for transmitting knowledge? ?

Glancing at the prompt in the lower right corner of the system panel, Li Boyang couldn't help but twitch the corners of his mouth.

The font size of this prompt is so small that if he hadn't stared at it, he would have ignored the past.

【Ding! The host's state of mind is improved, the heart demon tribulation is successfully destroyed, and a copy of the knowledge of the state of mind of the previous life is obtained.

Li Boyang stared at the three words [Heart Demon Tribulation], and suddenly felt a little afraid.

He didn't want to be a human being before, I'm afraid he was affected by this so-called [Heart Demon Tribulation].

But the question is that his strength is low now, how can he come into contact with the [Heart Demon Tribulation], which sounds like a relatively lofty thing?

Isn't it because he faced the [Chain of Order]?

My heart tightened, the title of [Immortal Evil Lotus Guest] is indeed very useful, and opening the evil seed state of [Evil Lotus Seed] is simply invincible.

Li Boyang originally thought that he would wait for the cooling to finish before continuing to use it.

But when you think of peeping into the deep-seated [Order Chain] in the state of evil seeds, it is very likely that you will be invisibly counterattacked and suffer from the [Heart Demon Tribulation].

He immediately stopped thinking about using it again.

If it weren't for the fact that he happened to see the nine people in the bunker and was baptized in his heart, he was afraid that he would die quietly.

Keeping it firmly in mind, Li Boyang calmed down and read the information transmitted by the system carefully.
