Lin Yun had become aware of the surveillance on the 7th day. He had been overdrafting his mind power by using Berserk Transformation for ten hours straight. But his soul became a lot purer after he woke up, his mind power also grew in strength and his perception naturally grew sharper.

But even though Lin Yun noticed the surveillance, he ignored it. Letting outsiders enter that sealed space was very dangerous in itself. There was nothing wrong with their host being cautious and monitoring them, so Lin Yun didn’t mind. In any case, the important parts of his research couldn’t be monitored.

What’s more, the mysteries and data researched would ultimately be copied for the Starry Sky College, so it didn’t really matter…

Lin Yun didn’t care about that matter, but he started thinking about other things. In ten days he had comprehended over fifty truth runes.

And with his growth over the past ten days, Lin Yun now only needed two hours to recover his mind power now. His current mind power was almost enough to support Berserk Transformation all day long.

After resting, Lin Yun entered his Natural Demiplane.

Only three quarters of the pillar in the center of the Natural Demiplane was emitting light.

This meant that the merging Demiplane almost reached the core of the Natural Demiplane. Once the pillar was fully illuminated, there would be no distinction between the Natural Demiplane and the Demiplane.

As for that pillar, it would become the most special area of the Natural Demiplane. Lin Yun couldn’t tell what kind of change would occur. After all, this was something that had never been recorded. Even the future owners of Natural Demiplanes weren’t able to develop a Natural Demiplane to that degree.

If there was any special change, he would only be able to understand when the time came.

He watched the development of the Natural Demiplane attentively. Its growth was stable, the Mana Vines had already turned into a huge patch of vines drawing mana from the void.

Mana Vines could only develop to this degree in newborn Natural Demiplanes, because only there could the Mana Vines tear mana from the void after germinating.

With these Mana Vines, the Natural Demiplane’s mana was taken care of.

The mana was gathered and liquefied into a mana lake, and a tenth of the mana lake’s mana was absorbed by the pillar. This was key to the merge of the Demiplane and the Natural Demiplane.

As he saw everything going smoothly, Lin Yun suddenly got an idea, and once he had that thought, he could no longer suppress it.

He could carve the truth runes he researched onto the Demiplane’s pillar!

Lin Yun floated above the pillar, and the more he thought about it, the less he could suppress that idea.

Although the Whisper Crystal was a very strange thing who contained unknown things, the truth runes were unadulterated mysteries, pure truth. Even after that future genius of the Starry Sky College went crazy and destroyed the Starry Sky College, the research of truth runes didn’t stop.

Because the truth runes weren’t evil, they were only a kind of mystery close to Laws. The research of truth runes was still ongoing when Noscent developed to its peak, but there has never been negative news regarding truth runes.

Since these were so powerful and contained mysteries close to the truth, it didn’t seem harmful to carve them onto the developing Demiplane.

The more he thought about it, the harder it was for him to suppress this crazy idea. After thinking about it for half an hour, Lin Yun couldn’t think of anything negative.

Even so, Lin Yun didn’t immediately give it a go, he instead cautiously pondered and decided to first carve the runes he had already comprehended.

The pillar was the most special area, but it didn’t completely merge with the Natural Demiplane. If the truth runes really had benefits, then it would be for the best. If it caused some negative changes, then the worst outcome was only the destruction of the pillar. That would only make his law power container disappear and he would fall back to being a Heaven Mage that had just advanced.

With the Natural Demiplane supporting him, and the fact that he walked out of the Gate of Rebirth, Lin Yun could be considered an innate Heaven Rank powerhouse. Even if something happened, he couldn’t fall back to the Archmage realm.

If there was an obstacle, he had to experiment…

Lin Yun recalled the truth runes he had comprehended and decided that the first truth rune he would carve would be the energy conversion truth rune that he had comprehended early on.

The barrier covering his body dissipated and his terrifying Extraordinary Power burst out. Suddenly, that Extraordinary Power attracted the Laws of the Natural Demiplane and the Earth, Fire, Water, and Wind Laws fluctuated alongside Lin Yun’s Extraordinary Power.

Mana, Extraordinary Power, Mind Power, everything converged together to condense a truth rune’s comprehension.

In an instant, a mysterious and perfect law rune appeared before Lin Yun. The law rune started slowly taking shape, forming triangles. Shortly after, four triangles converged together in the same spot, forming a 3D rune. The most perfect structure for law runes.

As Lin Yun’s mind power slowly poured into it, the mysterious aura exuded by the law rune became thicker and thicker.

Then, that law rune started revolving. As it revolved, it slowly turned into a flat rune, before turning into a strange and simple rune. It was like a character of a special language.

Lin Yun solemnly dragged this truth rune and slowly merged it on the upper part of the pillar.

As the rune came in contact with the pillar’s radiance, it immediately merged with the pillar.

But nothing happened after the rune was merged. This made Lin Yun frown…

Even something bad happening would have been better than nothing. Nothing means that there is no good development and no risk of his rank being affected. It also implied that truth runes have no effect towards the Demiplane.

But this was the most unlikely situation. After all, truth runes contained power similar to law runes. Whether it was good or bad, there should always be a small reaction. This situation was completely out of Lin Yun’s expectations.

Since there was no reaction after merging, Lin Yun kept going and condensed the 2nd truth rune.

…

There was still no change after merging the fifty truth runes he had comprehended.

Lin Yun sighed and prepared to leave the Demiplane.

But suddenly, the pillar shuddered and a special fluctuation appeared. The pillar shuddered even more fiercely as if there was a light earthquake.

But aside from the shaking, there was no other change. Five minutes later, Lin Yun suddenly sensed something and he looked into the distance, only to see a steam of water emitting a dense mana aura flying over from a distance.

If a Great Mage approached that dense stream of water, they might directly explode.

Lin Yun could see that the ten-meter-thick stream of water was formed from the Mana Water of the mana lake. It was actually forcibly attracted by the pillar…

After all, although the pillar absorbed mana, it was absorbing mana from the Natural Demiplane. The absorption of the mana of the Natural Demiplane would form a vacuum which was passively replenished by Mana Water.

How could it be that ridiculous… After all, the mana lake was over a thousand kilometers away from the pillar!

Lin Yun flew up, but he couldn’t stop this. That was a stream of Mana Water whose end couldn’t be seen. Even if he controlled the Natural Demiplane to stop it, he would be unable to prevent this from happening.

Anything going in between the stream and the pillar would be thoroughly destroyed, this was a pure mana attack crossing over a thousand kilometers. That terrifying speed carried terrible momentum and even Heaven Rank powerhouses could die in an instant…

Lin Yun blankly stared as that stream of water charged into the pillar. He expected the mana water to blast the pillar and destroy it, but that didn’t happen. The stream of water, carrying terrifying momentum, seemed to disappear instantly upon coming in contact with that pillar.

The mana rapidly disappeared inside the pillar and the entire Natural Demiplane shivered. All the lifeforms within the Natural Demiplane were in shock due to that kind of pressure, especially those simple insect lifeforms that had been nurtured by the Natural Demiplane. They were so scared that they couldn’t let out a sound. They got under the earth and didn’t have the courage to emerge.

Lin Yun silently calculated the amount of Mana Water and was scared witless. This was mana condensed into liquid form.

A single drop of Mana Water could completely replenish the mana of a newly advanced Archmage. Even Lin Yun, who far surpassed his peers in that regard, only needed a potion bottle of Mana Water.

But now, the Mana Water had transformed into a thick flood which travelled over a thousand kilometers to enter the pillar.

The water of the mana lake was rapidly dropping, and in merely a dozen seconds, the water level declined by half.

The light on the surface of the pillar rapidly spread to the lower half. It took less than ten seconds for the last quarter of the pillar to be covered in light, the pillar finally turned into a peak emitting colored radiance.

At that time, the force fiercely attracting the mana lake’s Mana Water dissipated, but the Mana Water that was still on its way was still carried into the pillar by its momentum.

After the pillar finished absorbing the remaining Mana Water, Lin Yun suddenly felt something…

That was a feeling of perfection, the Natural Demiplane and the Demiplane he had established were no longer separated, they were one and the same. The source of the Natural Demiplane and the source of the established Demiplane ended up fusing together.

Now, only one plane could be sensed.

After completing this step, Lin Yun felt as if he suddenly became aware of an error he had had in his comprehension of the Laws, that was because a flaw had been fixed and his control over the Natural Demiplane had reached the highest level.

It was like the Natural Demiplane had been established by him!

Thoroughly controlling a Natural Demiplane was a feat no one had been able to accomplish before the end of Noscent, but the Natural Demiplane was no different from the Demiplane he had created!

This gap was already large to the point where it couldn’t be explained, and there was too many benefits to keep track of them all at the moment.

Lin Yun was thoroughly dumbfounded. He hadn’t foreseen that the truth runes would actually be that powerful. He only comprehended fifty of them, yet they allowed him to perfectly fuse his Natural Demiplane with his established Demiplane and merge their sources perfectly!

Everything had stabilized by the time that pillar thoroughly turned into a radiant peak and great changes happened to the Natural Demiplane.

The peak was like a control center which controlled the Mana Water within the mana lake, transforming it into a drizzle that sprinkled over the entire Demiplane.

Then, the earth faintly shook and the original two to three-thousand-kilometer-wide land expanded once again. It stopped after expanding by another hundred kilometers and the surrounding ocean widened.

But the true change wasn’t the Demiplane becoming bigger, but something else.

A few small-scale volcanoes appeared in the south, while seawater started condensing into an ice field in the north. The earth started raising in the west while gales rose and thunder boomed over the eastern sea.

The earth, fire, water, and wind started showing signs of deviation. This was something that could only happen when the four laws were completely stable.

After these deviations appeared, the power of elements would appear, and it would no longer be under the form of pure mana. There was clearly more fire elements in the south, while water and ice elements clearly gathered in the north. The earth rising in the west meant that earth’s power grew even stronger there, and as for the east’s gales and thunder, it showed that the wind elements gathered over the eastern sea.

This wasn’t a bad thing, it was actually showing that the Demiplane had undergone its evolution. More advanced lifeforms would be nurtured from now on, they wouldn’t be like those brainless insects.

The clashes of different elements would make it easier for a variety of lifeforms to be nurtured. This was a wonderful start.

It was safe to say that mana would always be lacking during the growth of a Natural Demiplane, but the mana gathered by the Mana Vines already condensed a mana lake. This would be used by the Natural Demiplane when it reached a bottleneck.

But this was also normal. Natural Demiplanes couldn’t keep evolving unimpeded. But in theory, as long as the Natural Demiplane kept growing, they would never have enough mana.

And now, Lin Yun was looking at the mana lake’s original location. It already turned into a hundred-meter-deep hole. The Mana Water had already completely disappeared, but Lin Yun was smiling.

Because this was good. This was extremely good. He wasn’t afraid that the mana would be consumed, he was afraid that the mana wouldn’t be consumed.

The Natural Demiplane completed an evolution and the entire Demiplane’s mana density sharply fell a few dozen times. The lack of mana roused the Mana Vines in the north.

The originally excessive abundance of mana had made the Mana Vines’ expansion stagnate. After all, the sparser the mana, the more frantically the Mana Vines would grow and tear the void’s chaotic energies to turn them into stable and gentle mana pouring over the Demiplane.

Now that the mana lake was empty, the Mana Vines became a lot more energetic. At the start, the Mana Vines were already over a hundred meters in thickness and wriggled out of the Demiplane’s earth to rush several kilometers up and disappear in the void. It was unknown how long the parts in the void were.

The thickest Mana Vine seemed to have sensed the lack in mana in the Demiplane and immediately burst out with its strongest energy. It swayed its terrifyingly huge body and rapidly split into two several-dozen-meter-thick huge vines to start tearing apart the energies from the void.

As they devoured that power, the two thick Mana Vines rapidly expanded and more and more mana came from the void.

Mana Vines of all sizes took this opportunity to start frantically dividing their bodies, while some of the smaller Mana Vines were maturing at a rapid pace.

The chaotic energies torn from the void were digested and transformed by the Mana Vines into pure and smooth mana which very slowly filled the mana lake.

The dense mana of the Natural Demiplane also started rapidly increasing. Based on that kind of speed, it would take half a day to recover the Demiplane’s mana. As for the mana lake, it would be slowly filled.

Lin Yun was stunned as he watched the changes of the Demiplane.

Natural Demiplanes were a pain to develop, but it wasn’t in regard to their size, because as long as they had enough mana, they could keep on expanding. With a Mana Vine, the size of a Natural Demiplane was bound to continuously increase.

But the evolution of the Demiplane’s essence in itself was extremely troublesome. It was just as troublesome as calming down the four elements at the early stages. Every step was evolving the essence of the Demiplane, and this evolution of essence would become more and more troublesome. Every step was harder than the last and required more than just mana.
