If Mo Chengjun is asked to rank the 'strange phenomena' he has seen and heard after coming to this immortal cultivation world, the first thing to bear the brunt of it must be a ghost.

There is no way, people die as ghosts, and even the world after death-Yin Earth, is a field that so many scientific giants in the previous life wanted to peep into, but they couldn't even squeeze through the cracks in the door.

A mysterious collapse of the lake!

And to say that he is ranked second, Mo Chengjun has to recommend the use of space.

Compared with the world after death, the cognition of time and space is much stronger in the previous life.

The most classic is the "Theory of Relativity" of the scientific giant, which has greatly changed people's common sense of the universe and nature, and put forward new concepts such as "four-dimensional space-time", "curved space-time" and "space folding".

But concepts are really just concepts, and with the support of theories, there is still a distance of 108,000 miles from practical application.

Even in Mo Chengjun's era, outer space exploration and colonization have become the main theme, but distance in the sense of space is still the biggest problem in front of me.

Light-speed spaceships driven by curvature only exist in science fiction, let alone interstellar portals and the like.

But when it comes to this world of cultivating immortals, everything is different.

First of all, not to mention that the storage bag is very popular, and it can't be done for every immortal cultivator, but in an immortal sect of the level of the Galaxy Sword Sect, the inner disciples are all issued by the system.

Although the space inside is really not large, you can't be a cadre for the village chief, and Wuling is not a car.

This is still a means of using space folding, and it has become popular.

Besides, there are many magic weapons that are engraved with the prohibition of 'size and size', so much so that it can really become bigger and smaller.

Although there is also a limit, it can't be as big as Sun Dasheng's golden hoop stick, so exaggerated to the extent that it can pierce the sky, but for the real immortal cultivation power, this seems to be a routine operation.

There are many great powers who like to practice the mountain peaks into magic weapons, and they usually put them away the size of a palm and carry them in their arms.

When the fighting method is thrown out, the body is revealed, and the mountain-like mountain that covers the sky is smashed down, so I ask you if you are afraid?

There is also the Hengsha mustard seed bowl brought in by the green bat, although it has now become a glazed mustard seed bowl, but the space inside is also real!

All of this, if you look at it from a point of view, aren't they all routine operations?

But from the perspective of a scientific research elder, this is very unscientific.

Why did you engrave the prohibition of 'size and size', so that this thing can become bigger and smaller at will?

How can you just take the space inside the bowl and hold a sea of sand inside?

Mo Chengjun felt that if he studied these thoroughly, and then returned to his own world, he would write a few papers casually and throw them out would have the effect of 'blowing up the street'.

His portrait is definitely enough to be hung in the highest hall of scholarship for future generations to worship.

It's exciting to think about that picture......

What a fart!

He has slept for three thousand years, even if he becomes an immortal and an ancestor in the future, and has a chance to return to Blue Star, he still doesn't know what he will become?

Now that I think about it so much, I have a hairy use, so I might as well do some research in a down-to-earth manner!

However, Mo Chengjun actually didn't study anything useful.

It's just that after the "Book of Heaven" was written, from the point of view of the "Book of Heaven", it seems that there is really some explanation.

In fact, it is dark energy or dark matter that is leveraged by the spiritual power of heaven and earth, and then it is a possibility to twist or fold space with dark energy or dark matter.

Well, there are many unsolved mysteries, and Mo Chengjun is not even interested in the records in the small book this time.

I only feel that if this is studied thoroughly for him, it is estimated that there will be no boundaries and secrets in the eyes of immortal cultivation and science.

That's just too far away.

However, since Mo Chengjun wants to use the 'cave sky' as his safe house, he has worked hard.

Not to mention the insight into the essence of the 'cave sky', but for its attributes, characteristics, nature and function, it must have been deeply understood and studied.

Originally, Mo Chengjun thought that the 'cave sky' was a bit of space that was constantly pulling and expanding, similar to a balloon, and after it was blown up, there was a lot of space inside.

In the Buddhist saying, it is a flower and a world, and a leaf and a Bodhi.

But the problem is that after really in-depth research, especially after entering the Wutong Cave Tianyi Group, he felt that this point of view was a bit unreliable.

First of all, the balloon is blown up, which also takes up external space.

But in fact, the 'cave sky' is independent of the original world.

It is safe because it does not exist in this world except for the anchor point that connects with the world.

Even if you have an immortal war in this world, the sky is dark, the sun and the moon are dark, what can you do with me?

And the only way to enter and exit the cave is to pass through that anchor point, which is the entrance to the sky.

If you don't have the right way to open it, you can only stare dryly, even if you know that there is a cave here.

The most infuriating thing is, alas, do you think that the entrance to the cave sky, that is, the anchor point, cannot be moved?

No, it's actually movable.

Although it takes a bit of effort, this 'gate' is mounted on the 'car' and can be run at any time.

All of the above, almost everywhere says the safety of the 'cave sky'.

And this is also one thing that must be put on the agenda after those who have become immortals and ancestors-to open up a cave of their own and create a safe 'home' for themselves.

It's just that you really have to admit that the materials and spiritual objects consumed by this cave heaven are not necessarily bought with money.

Even if it is an immortal, it may not be able to take it.

So, 'wanting' and 'whether you can do it' are two different things!

In a sense, Mo Chengjun is lucky, lucky beyond imagination.

The 'Mahogany Secret Record' left by the Ning madman solved the rarest of the Two Realms Stone.

And the Evil Ghost King sent him the 'Five-Colored Earth' again, and although God obstructed him repeatedly, he was stunned by the method of recovering the Eye of the Spiritual Spring in the dormant period that he had made.

As a result, he has now built a small foundation, and he dares to look at the cave.

It's just that this time, Mo Chengjun was really scared enough by the 'kidnapping' of the disciples of Mending Heaven, and his sense of security fell suddenly.

He really didn't want to suffer again, and he didn't want to pin his comfort on others.

Therefore, there is a freshly baked "Big Plan", and there is also today's line.

……

Deep in the Great Wilderness Mountains.

It is already tens of thousands of miles away from the Galaxy Sword Sect.

Night, top of the clouds.

The goshawk flapped its wings and spun abruptly, revealing Mo Chengjun's body.

He stepped on the auspicious clouds, his eyes flashed, he looked down, only to feel that in the clouds and mist, the mountains and rivers on the ground could be faintly seen, as small as ants.

Looking at the sky again, I only felt that under the dark and heavy curtain, there were small holes, and the brilliance flowed down like substance, and the bright galaxy seemed to be within reach.

Under the sky.

above the earth.

Mo Chengjun only felt that this place was extremely suitable.

He took a deep breath and tried to calm his slightly excited mood, even if it was him, he was a little unable to control himself for the upcoming big scene.

After a while, Mo Chengjun took out the array plate that had been prepared long ago and a few matching magic flags.

After pinching a few tricks, he threw out the magic flag again, and a set of hidden formations had been arranged.

Although it was between the clouds, it was already very hidden, but Mo Chengjun still didn't want to make the slightest mistake.

It wasn't until the formation was foggy and completely integrated with the surrounding clouds that Mo Chengjun made another move.

He took out the Two Realms Stone, held it in his palm, looked at the dark leaf-like stone, and took a deep breath.

Then, without hesitation, it is a grip.

What a strength he was, this grip directly crushed the seemingly indestructible stone of the two realms.

Bang!

Stone flakes that were almost visible to the naked eye cracked, shards flew, and darkness rippled out, enveloping him in an instant.

The sky was spinning for a while, Mo Chengjun only felt a strong sense of discomfort coming, and when he saw his surroundings clearly, he only felt that everything had changed.

He was still in the clouds, not up to the sky or down to the earth, and the stars and the mountains were still there.

However, everything seems to be separated by a layer.

It felt, to use an inappropriate analogy, that he was in the water, looking around with wide eyes.

He could still see the sky and the underwater, but the turbulent currents made his vision so strangely distorted that it seemed like the whole world was wandering.

Of course, if you blink and take a break, when you look again, it seems that the world is different as far as the eye can see.

Filtering through the shaky scenes, you look closer, and it seems to be dark all around.

What you can see is darkness, boundless, dark and deep, but not cold, not terrifying.

It's just there, there, immutable, and it doesn't matter how you feel as a human being.

Is this the 'position' of the cave sky?

This was the thought that flashed through Mo Chengjun, but he didn't dwell on it too much, because he didn't have much time.

The Stone of the Two Realms.

A long time ago, Mo Chengjun thought that it was used to open up the cave, but in fact it was not, and it didn't have that much ability.

Its role is simply to send people into this unique level of the world.

Please allow Mo Chengjun to use the word 'level' to describe it, but he really doesn't know how to express it, which is the most appropriate thing he can think of now.

But this kind of 'entry' is also effective.

If he can't stabilize the passage he enters after this point in time, then I'm sorry, I'm going out, but there is no second Two Realms Stone to let you in.

Without any further delay, Mo Chengjun quickly took out a set, seven seven and forty-nine spiritual spring eyes.

Then, a huge array disk appeared out of thin air, and the Eye of the Spirit Spring was placed in a specific position by Mo Chengjun.

Immediately after that, several spells were pinched, and the surging mana poured in, like a series of connections, activating the forty-nine spiritual spring eyes.

It's really just a moment, and the rich heaven and earth spirit is pouring out as if you don't want money.

In Mo Chengjun's eyes, the colorful spiritual machine suddenly formed waves, expanding rapidly outward like a tidal wave.

The expansion of this spiritual machine was so fierce that it even swept Mo Chengjun out.

The richness of this spiritual power caught him off guard, and his head was dizzy for a moment, as if he was drunk with oxygen, and his mind was dizzy and dizzy.

But Mo Chengjun still stabilized his body as fast as he could, took out a colorful stone, and accurately threw it in the center of the array composed of the Eye of the Spirit Spring.

That's the heart of it all, the place that's been reserved for it.

Syllable!

There seemed to be a light echo, and then, a huge amount of heaven and earth spirit had a catharsis, and the five-color earth was like a sponge frantically absorbing the rich heaven and earth spirit machine.

Then, as if alive, it expands outward, grows, expands.

It was just a few dozen breaths, and a five-colored land suspended in the void was created.

At first, it wasn't big, it was just a place to stand on a cone, but as time went on, the five-colored land expanded rapidly, and judging by the speed, it became faster and faster.

Mo Chengjun finally stood on the ground, only feeling so solid and down-to-earth, he also jumped, feeling great.

But you think that's the end of it?

Wrong!

And that's just the beginning!

He had saved up a full nine sets of bases, a full four hundred and forty-one spiritual spring eyes, and this was where he went!
