This dungeon has mushrooms growing on it.

Chapter 229, page 228: The Seal
A five-layered mushroom forest.

The once glowing mushroom forest has been reduced to a mess, with mushroom trees lying scattered about, their broken branches and caps covered with vicious claw marks and teeth marks.

In the center of the ruins, a spatial rift, about four meters long, opened menacingly.

On the other side of the rift lies a lush, verdant primeval forest, full of life yet extremely deadly, as evidenced by the monsters that emerge from it.

A worm with a thick shell, attracted by the burnt smell wafting from the fifth floor, slowly poked its massive body out of the crack and clumsily crawled out.

However, just as its hard-shelled body had crawled halfway through, the crack suddenly contracted!
The unstable edges of the rift transformed into spatial blades, and the worm's hard shell was as thin as paper in front of the spatial rift, easily cut through!

Even more terrifying is that the edges of the fissure are deeply embedded in its soft flesh, causing it to suffer the pain of being cut with every little movement. For a time, it was caught in a dilemma and could only tremble in vain in excruciating pain.

But it didn't know that this was its last chance to escape.

As time went by, the crack continued to shrink and slowly closed... eventually disappearing without a trace, leaving only half of the insect's corpse in the original place.

……

Oh!
So this is what it feels like to repair cracks!

Within the core area, the enormous crystal monument still shimmered with a pure blue light, and Lin Jun's soul remained trapped inside.

The suction force originating from the core did not stop, but Lin Jun was no longer worried that it would drain her dry.

When Lin Jun's soul completely filled the crystal tablet, a wondrous cycle was formed!
The core continuously draws in his soul essence with a constant caliber, and at the same time, expels the soul with the same constant caliber.

Lin Jun's soul was now connected to a unique dual-channel circulation system, forming a semi-permanent link with the core of the underground city in a dynamic and balanced manner.

The reason it's called "semi-permanent" is that after obtaining core access, Lin Jun can forcibly extract her soul from the core based on her senses.

However, firstly, the dungeon still requires computing power to maintain, and secondly, an overly forceful approach might cause unpredictable consequences. Therefore, maintaining the status quo is the safest option for now.

Controlling the core means that Lin Jun now has extremely high authority within the Purple Crystal Underground City.

In theory, he can control the punitive lightning, access permissions, and even spatial transformations within the dungeon...

The reason it's only theoretical is because in practice it's like fixing code, and Lin Jun is a complete novice who can only figure it out by trial and error!
The reason why the electric arc from the Yellow Book was so powerful was simply because within the core hall, accessing permissions was as straightforward as moving a finger. Once outside the core area, the complexity and difficulty of the operation increased exponentially!
Fortunately, repairing spatial rifts does not require advanced technology.

He only needs to send the computing power provided by his soul to the location of the rift, and the dungeon will automatically repair the rest.

Of course, since the soul needs to continuously provide computing power, it will naturally have an impact on Lin Jun as well.

The most direct impact is that the control capacity of the Puji Legion is permanently reduced by 500 units, and additional capacity will be occupied when repairing rifts.

Therefore, faced with the current state of the devastated underground city, Lin Jun could only adopt a conservative repair strategy—prioritizing the cracks that posed the greatest threat and could cause significant trouble, while dealing with the rest slowly.

As for the other complex functions of the dungeon, we can only explore and figure them out as we go.

However, Lin Jun had a strong intuition: the lightning bolt, as a punishment measure, was probably the button in this complex permission system that was easiest to guess.

Besides the core item, Lin Jun also had an unexpected gain.

Inspiration LV1

Simply put, his perception was pried open, although he was only at LV1 at the moment. Apart from his own vast and clear cyan soul, the other souls in his weak perception were as blurry as if they were seen through a thick fog. But this was still a leap from 0 to 1!
This skill wasn't stolen; it was awakened through personal experience of having one's soul pulled apart by the core.

Knowledge and power in the realm of the soul have always been a blind spot for Lin Jun.

As this crisis has revealed, his carefully laid plans, whether it be the transfer of the main body or the cutting of the bacterial network, are all at the physical level.

As a result, on a spiritual level, he was easily outmaneuvered by the Yellow Book—it wasn't even a soul attack, just a trap that exploited a core mechanism—and he almost lost. If he had had this "inspiration" earlier, he might have been able to see through the Yellow Book's trick.

There's a reason why Lin Jun hasn't thrown the Yellow Book directly into the void yet; it's currently in a delicate state, with a tiny bit of Lin Jun's soul occupying its cover.

At first, it tried to squeeze Lin Jun out, but every time it squeezed a little out, Lin Jun would squeeze a little in, thus maintaining a dynamic balance. In the end, the Yellow Book had no choice but to give up.

This led Lin Jun to the essence of the Yellow Book—something that resembles a soul but is not a soul.

It's unclear what exactly it is, but obviously, as long as you use your own soul to envelop and crush it, you can easily destroy the Yellow Book. In a true sense, life and death are in Lin Jun's hands, which is even more direct than being parasitized by mycelium.

Mycelium parasitizes; if you move to a place not covered by the mycelium network, you will not be affected.

Based on her experience with soul contact ignoring space, Lin Jun could resolve the issue at any time, no matter how far she threw the yellow book.

Speaking of which, the Yellow Book mentioned some important intelligence at the end.

Snapped--

With a flick of its tentacle, the tattered yellow book, its cover still bearing blue patterns, was tossed onto the cold ground like trash.

Now, it's difficult to distinguish this tattered book from the previous sacred texts by sight alone.

He kicked the notebook away with a thud: "Didn't you say there was more important information? Stop playing dead and confess!"

After waiting for a while, there was no response.

A tiny arc of electricity struck precisely, and a burnt smell accompanied by wisps of smoke rose up.

Still silent.

Then... keep the power on!

The electric arcs were like whips, one after another, until the yellow book was almost turned black.

The voice, as if suddenly realizing something, exclaimed in surprise: "Oh dear! I'm so sorry, Lord Holy Scripture~ I forgot that you don't have a single page left, so you can't write on the cover!"

Soon, outside the core, a minotaur was sacrificed to the Yellow Book.

Sensing the faint soul entering the cover, Lin Jun pinched the source of the yellow book.

"Listen up," Lin Jun's voice came through the audio feed, "From now on, no soul is allowed to be saved in the cover! If you dare to save it even once, I'll crush you! Understand?"

Under the threat, a slight tremor ran along the spine of the book, and a brand-new, but obviously fragile, page, with a kind of urgent "will to survive," quickly grew out.

As soon as the pages were completed, the yellow book hurriedly began to prove its value!
[Stop the shock! Stop the shock! I'll tell you everything!]
[The secret lies behind the small door at the core!]
……

……

……

Several poopy creatures stood in front of the small door. If Lin Jun, who held the highest authority, wanted to, she could easily push the door open.

but--

"What do you mean by sealing away one-sixth of the Demon King later?"
