To be honest, when he came to this world, Mo Chengjun had seen too many magical things.

Those fairies and monsters that only exist in mythology have appeared in front of his eyes one by one, even if it has been many times, but he still feels incredible.

There are also those methods, supernatural powers, formations, talismans, and pills, which seem to be able to be explained by science.

He did the same, but looking back, the magic was still everywhere.

And all these miraculous places, the most unbelievable thing for Mo Chengjun has to be the method of opening up the cave.

In the void, between the three-dimensional and the four-dimensional, a piece of earth is carved out of thin air, and plants can be sown, multiplying, and expanding......

This kind of thing, if he hadn't experienced it himself, or even practiced it more than once, he might not have dared to believe it.

It can be said that all kinds of wonderful methods are the most important in this way!

It's just that this thing is also really high-end and high-grade, even if it is an immortal sect of the level of the Eight Great Immortal Sects, the accumulated information is very limited.

Mo Chengjun's collection of all kinds of secret recording exercises is hundreds of thousands of volumes, but when it comes to Dongtian, it is only a few bookshelves.

Most of them still exist in the form of travelogues, sightings and heard-notes, leaving some speculations that are difficult to distinguish between true and false.

The real substantive content is not as much as that 'Mahogany Secret Record'.

It was only at this time that Mo Chengjun could be regarded as the most complete and systematic method of opening up the cave.

Under the Sycamore Immortal Plant,

on the recliner,

Mo Chengjun stretched his golden body of merit, closed his eyes slightly, as if he was sleeping in a non-sleeping room, and there were messages flowing through his heart.

Then, an enlightenment arose in my heart......

It should be said that the information given by the Candle Dragon Dragon Monarch is very 'solid', not only the technology of opening up and building the Immortal Domain, but also a series of evolution processes of this method.

It was also from these materials that Mo Chengjun was able to determine that the method of opening up the cave was derived from the Heaven Replenishment Sect, and it was also the predecessor of the law of the Immortal Realm.

Its biggest feature is to divide the connection between the cave and the present world as much as possible, and while maintaining its independence, it is also necessary to complete the internal self-circulating ecosystem, which can achieve the purpose of self-sufficiency.

In other words, it is shaping a new world that is independent and complete.

Take a look at this, isn't it a little familiar, similar to the shelter that was only opened during the catastrophe.

In fact, according to the records in the jade slip, such characteristics are what the Heaven Replenishing Sect most desires and needs in that special era.

It's just that in the process of follow-up development and construction, the Mending Heaven Sect also found that this routine seems to be very good, but in fact, there are many problems that cannot be solved.

For example, the materials needed for development and construction are really exaggerated, exaggerated to the point that even the volume of the Heavenly Sect can hardly bear it.

Please note that although the Heaven Mending Sect was large, what he needed to build at that time was not one or two, but it had to be able to accommodate almost the entire world.

For example, it takes a long time for the cave to enter a virtuous circle.

Don't look at the area of the Heavenly Court's blessed land is 'huhu' skyrocketing, but in fact, it is the result of Mo Chengjun smashing a lot of spiritual spring eyes, and it is also the resources that he saved by mastering the 'spiritual spring eye recovery method'.

But where does a normal cave have this capital?

It is only after being promoted to the blessed land, opening up the spiritual vein, completing the self-division and reproduction of the spiritual machine, and the creation of the spiritual spring eye, that it is possible to form a virtuous circle.

But these things take time.

If there is really a thousand years, take your time, it doesn't matter, but unfortunately, even the great power of the immortals rarely has such a long life and patience.

In addition, the growth of the Cave Heaven Law is also worrying.

According to what is written in the information, after the opening of the cave, it is good to say that it will be upgraded to a blessed land, but it is not easy to reach the small world.

In the long history of the Mending Heaven Sect, there are only a handful of people who can reach this level.

As for what Mo Chengjun had in mind, he broke through the dimensional wall, entered the four-dimensional plane, and achieved the world......

This is just a concept, a delusion of the original designer of the cave.

Anyway, for thousands of years, the Heaven Replenishing Sect has worked hard in this regard, and the investment source has never succeeded once.

Of course, none of the above is a problem, and even if there is a problem, it is not impossible to overcome it.

But the last point is the fundamental reason why the method of the Cave Heaven was gradually abandoned by the Heaven Replenishment Sect, that is, the continuous collapse effect of the artificial ecological circulation system.

This statement was not put forward by scientific researchers, but a new concept that was put forward in the later stage, after the artificial ecological circulation system continued to collapse.

The Mending Heaven Sect found that when the Cave Heaven Blessed Land could not maintain positive and continuous growth, the internal ecosystem would develop in the direction of collapse.

What does that mean?

That is to say, if we really treat the cave as an independent world and cut off all interaction with the outside world, then the artificial ecological circulation system will develop in a bad direction and never return.

No matter how ingenious your biological chain is designed, how well the personnel control is, and how perfect the circulation of food and drinking water is......

These, no matter how good you do, it is useless, and the artificial ecological circulation system will inevitably collapse!

As for the reason, there is no definite number, but there are many theories.

Some people say that it is the imbalance of microorganisms, some people say that it is the natural limitation of the five-color soil foundation, and some say that it is the decline of heaven and earth.

And more people believe that this is a defect in the mezzanine of the dimension, and the rules are incomplete, so it cannot really last.

As for the specific solution, there are two main ones.

This first way is to maintain the positive and continuous growth of the blessed land, and the way is that as long as you can win, any contradictions will be covered up.

Mo Chengjun's Heavenly Blessed Land is like this, anyway, he has not encountered any Honkai effect.

Of course, since he opened up the Cave Heaven, this realm has been growing and expanding at an extremely high rate, and it has not gone downhill.

The second method is aimed at the defects of the dimensional mezzanine, which is the case, and it is good to directly change the status quo.

Specifically, either up or down.

'Go up' means to upgrade, become a world, break through the dimensional wall, that's really awesome.

It's not just as simple as solving a problem, but there are a lot of additional gains.

Theoretically speaking, if you enter the four-dimensional world, that is the four-dimensional life, and the cards and abilities are not conceivable for three-dimensional carbon-based life.

Mo Chengjun still remembers watching a video a long time ago, saying that four-dimensional life looks at three-dimensional life as if he was reading a book, time and secrets have lost their meaning, and I don't know if it's true?

Of course, this road is not easy to follow.

Or rather, so far, no one has walked through.

However, 'up' is not good, but 'down' is still okay at the beginning, the four-dimensional level is not reached, and the three-dimensional world is at your fingertips.

And the fairy technology is a downward extension, which is the expansion and compatibility with the outside world after giving up independence.

Of course, the reason why this is the case is also the inevitability of the times.

There is a saying that every era has a choice for each era.

The independence and concealment of the blessed land is the choice in times of war.

But later, under the leadership of Long Zu, the demon clan won the war with the desire world and drove them out, so naturally, there was no need to hide.

On the contrary, if they want to counterattack and spread the war to the realm of desire, they will no longer have a refuge, but a forward base.

As a result, the fairy domain technology came into being.

The characteristics of the fairy domain technology are openness, expansion, and it is based on the blessed land of the cave, and after completing the self-division and reproduction cycle of the spiritual machine, it opens the door of the cave.

In this way, the spiritual opportunity will spread outward and can spread out on the barren land.

And for immortal cultivators, with the spiritual opportunity, it is equivalent to having all possibilities.

They can shape mountains and spiritual veins, they can gather rain and sow seeds, they can spread life and multiply species.

Eventually, a living planet similar to this main world with a complete ecological circulation system was born.

Of course, not all barren planets can open up fairy realms, and some basic conditions must be met.

For example, it must be a solid planet, with a complete earth and sky, and preferably with plenty of water.

It doesn't matter what the air is in, because it can be adjusted, but it's better to have an atmosphere that can be easily modified.

In addition, there are unique resources that can be combined with spiritual particles to develop into pillar mineral deposits.

There is also the distance from the sun, preferably neither far nor close, with a clear day-night cycle and plenty of sunshine.

Do you feel like it's too much to ask?

Mortals and monsters who are not immortals are so fragile, like a drop in the ocean.

Moreover, these conditions seem exaggerated, but it is much easier than finding a perfect life planet in the universe.

Find a few more galaxies, you can always find them!

According to Yu Jian's records, an immortal realm like 'Guanghan Palace' is actually nothing, and it belongs to the inferior grade of a small immortal realm.

It's just that it's important because of the location.

The pinnacle of the Heaven Mending Sect is actually nine super-large immortal domains connected to each other, covering the entire planet, and then taking hundreds of years of continuous evolution and debugging, finally completing the transformation of the entire planet.

It is a desert in the universe that has been completely turned into an oasis, a man-made miracle, and a living planet that has been grazing.

Even through the jade slip, Mo Chengjun can feel the pride and pride that is about to overflow the screen.

In fact, it's something to be proud of.

Even Mo Chengjun couldn't help but sit up straight when he saw this.

Just kidding, 'war forward base' and 'herding life planet', those are completely different things, okay?

It seems to be one and the same, but it is an artificial planet of life!

It is equivalent to saying that this world is no longer completely irreplaceable, and it also represents the Heaven Replenishing Sect, which has truly embarked on the interstellar era.

This is the height that the blue star of thousands of years ago has not been able to reach.

It was only at this time that Mo Chengjun realized a little hindsight.

Why did the Shattered Moon Demon Lord come here and do so many bad things, but only one Ying Long Longjun chased after him?

It's not that Ying Long Longjun is far behind, but he is at most comparable to Candle Dragon, and he plays an auxiliary role.

However, if the two armies face each other, one side is stolen, and even the imperial city is besieged, what will be the result?

Naturally, the army in front retreated to defend, and then sent the most powerful army to relieve the siege of the imperial city.

If this world was the only source of troops for the Heaven Replenishment Sect, it was estimated that the ancestral dragon would have already run back.

But now, the Mending Heaven Sect has a follow-up choice.

Frankly speaking, Mo Chengjun was extremely interested in the technology of the 'herding life planet', especially the specific method of linking the nine large immortal domains, but there was no one in the jade slip.

Thinking about it, even for the Mending Heaven Sect, this kind of means is also the ability to press the bottom of the box, and it is purely for the sake of showing off.

In the Jade Slip, the technology of the development and construction of the fairy domain is completely recorded, which is divided into seven parts.

They are "Immortal Domain Positioning Method", "Cave Heaven Exploration Technique", "Blessed Land Placement Method", "Spiritual Realm Exploration Technique", "Reproduction and Resting Sutra", "Pioneer Two or Three Things" and "Immortal Harmony Method"!

Among them, the "Immortal Positioning Method" is about how to roam the galaxy, how to choose the right planet, how to find the best land, and how to choose the location where the immortal domain is completed.

This series of methods, which looks simple, is actually particularly important, but if the choice is not appropriate, there will be a lot of trouble in the future.

and then there is "Cave Sky Opening Technique", which is the content that Mo Chengjun is most familiar with.

How to shuttle through dimensional gaps, how to place five-colored soil, how to stimulate the growth of the earth, how to plant flowers and trees, how to form the initial cycle of spiritual energy, how to maintain the existence of the cave sky, etc......

It is worth mentioning that the Heaven Mending Sect is worthy of being the birthplace of the Cave Heaven Method, and they have accumulated far more experience in this area than Mo Chengjun.

For example, when the five-colored soil spread into the earth, they began to shape the terrain and landforms.

This is to prepare for the formation of spiritual veins in the later stages.

For example, they have a strict plan for planting flowers and trees.

Where can trees be sown, where is the right place for spiritual grass, where can spiritual valley be planted on a large scale, and where is the best place to do nothing......

It can be said that they have made the best arrangements while maintaining the stability of the earth.

And most notably, in order to ensure that the cave does not collapse quickly, they strictly limited the number of dings that should be inside.

A place like the Heavenly Court Blessed Land, which has a population of tens of millions at every turn, is rare even in the Heaven Mending Sect.

But who said that Mo Chengjun has sufficient resources?

Rich and capricious, that's what he's talking about.

The content of the "Blessed Land Placement Law" is naturally how to upgrade the cave heaven into a blessed land, how to form spiritual veins, how to complete the division and derivation of spiritual machines, how to create the eye of spiritual springs, and how to develop various spiritual ores......

In fact, this part of the content is what Mo Chengjun urgently needs.

Because, there are various experiences about the shaping of spiritual veins, there are techniques for making the eye of the spiritual spring, there are precautions for the cultivation of various spiritual mines, and so on.

Mo Chengjun had to admit that compared to the experience accumulated by the Heavenly Sect for thousands of years, the layout in the Heavenly Court's blessed land was extremely rough.

He only made a slight estimate that if he followed the method of mending the Heavenly Sect, the various revenues of Heavenly Court would have to increase by at least fifty percent to several times.

Especially regarding the part derived from the spirit ore, the formation provided by the Heaven Mending Sect can greatly reduce the time and expand the scale, which is indeed a qualitative leap.

As for "Spiritual Realm Exploration", we have to make it clear what is the spiritual realm?

Maintaining strict independence and almost not opening to the outside world is a blessed land. But if it is open to the outside world and takes the path of the fairy realm, it will not be a blessed land.

It has a new name, Spiritual Realm.

It can be understood as a secret realm specializing in the production of heaven and earth spiritual machines.

This step is also the watershed between the original version and the way of the fairy realm.

Its content is about how to move mountains and reclaim the sea on a barren planet, lay out formations, form a closed loop, and finally directly open the blessed land and let the spiritual machine gush out.

Then, let the original spiritual machine cycle expand externally, and include the barren land into the scope, and with the heaven and earth spiritual machine, there is all possible.

First of all, thank you for the 10,000 points of reward of the sword in the corner of the rivers and lakes, I really didn't expect that there would be such a large reward in this book, I almost jumped up with excitement.

I can only say, thank you for the reward!

Then, this chapter is actually not finished, and there is not enough time, so I will continue and send it early tomorrow......
