The assassin's troops, slowly advancing through the rocky caverns.

The damp saltiness filled Lynn's senses, the ground was full of standing water, and the quiet space was filled with the sound of 'ticking' water from time to time.

It's an abyssal place, beneath the plague islands, and maybe even below the seabed, but here...... and not shrouded in darkness......

There are many wonderful creatures here, some like plants, with branches, glowing blue creatures everywhere, and around them there are some trilobite-like arthropods and worms, and even some fluorescent starfish.

And there were creatures that Lynn was familiar with, and there was a small group of empty jellyfish floating in front of Lynn's troops, I don't know how long they had been living here, but they all seemed to be doing well.

The creatures weren't infected by the fungus, their light was self-inflicted, and the plant-like creatures were a species of coral, and they grew in small puddles of water, which Lynn reckons for food.

It's like an undersea environment, with a lot of water, but it's not completely submerged, maybe they have some way to drain the water out? Or will the water be consumed for some reason?

The assassins gathered together and moved slowly, the roof of the cave dripping cold water on them from time to time, and there were also fungus growing here. But in those places where there is no water on the ground, there are some mycelium and mushrooms, which dodge the water dripping from the puddles and cave roofs, but they can't spread out.

Could this be the place where the head of the plague fungus is located? It is indeed possible that the group of assassins felt some special signal here, which was constantly being emanated.

In the process of moving forward. Lynn also noticed that there were many small openings on the roof of the cave at intervals. If you drill into these small holes and go up. You'll reach a mud cavern, and then go up again to emerge from the Plague Island.

These caves are the caves where the head of the plague is located, and sure enough, as Lin thought, this underwater cave at the bottom is connected to all the islands.

However, this place felt different to Rin, who thought that there should be some creatures here that were creating the Plague Head, or that there were a lot of mushrooms storing energy, but she didn't expect that there were so many sea creatures living here......

Lynn headed in the direction of the strong signal. Going deeper, the strange thing is that the deeper you go, the less creatures around, and the environment is relatively dry, the water on the ground slowly disappears, and the cave becomes more spacious, with many round stone pillars that feel like they are used to support the cave.

No, it's not a stone pillar.

An assassin approached the stone pillar and gently scraped some crumbs from it, after eating it. Lynn discovered that it was a hardened fungal structure, and this one had become quite solid inside. It can indeed be used as a 'support column'.

This hardened structure...... It feels like the fungal fossils you found in the salt cave.

Sure enough, they must have had some connection in the past, and Lin felt that these fungi should not have been hardened by something, but that they themselves would become like this under some circumstances, and that all the fungi would work together.

But what happened to them? If known, this could be the key to exterminating them......

There weren't as many puddles here as there used to be, but there were still some creatures that Lynn found to be more familiar...... Ancient squid.

This ancient squid is distinctly different from the species on the northern continent, they are twice as large as there, about twenty centimeters, and have a blue ring-shaped markings all over their bodies, which do not seem to change as their bodies change color.

They seemed to be in groups of ten in the watering hole, and when Lynn's assassin approached to observe them, they did not appear to be afraid, but instead observed the assassin curiously.

Lynn wanted to call them 'Blue Ringed Squid', but the name didn't seem interesting, so she called them 'Abyssal Squid'.

I don't know what the intelligence of this 'Abyssal Ancient Squid' is different from that of the North Continent, but usually similar species are not too far apart, and the two of them may mate and give birth to new species.

Maybe you should grab one and give it a try......

Thinking about it, Lin let the hunter get close to the puddle, and the abyssal ancient squid, who had not seemed to be afraid, instantly swam into the mud and sand at the bottom of the pit, and they kept burrowing into it, and all of a sudden they disappeared.

After watching it for a few seconds, Lin decided to forget it, let's catch it next time, this army is not here to study and explore.

Lynn then continued to follow the signal and head deeper into the depths, where there were no more puddles of water around, and there were no creatures, and without the glowing creatures, the environment was dark.

At this time, the assassin glowed, and the whole cave was much brighter again, and Lynn saw that there were many cone-shaped pinnacles on the top of the cave, I don't know if they were hardened fungi, and there were some shiny things around it that reflected the light.

This is...... Crystallized?

Lin gathered the light of the assassin and found a crystal standing on the ground, this crystal seemed to be the same as the one in the Kibucha worm in the Northern Continent, Lin had seen it in the sea before, and usually there were ...... near these crystals

Lynn asked the assassins to look around, and sure enough, they saw a number of creatures moving around, they looked like scorpions, only five centimeters in size, quite small, but their bodies were covered in crystalline carapaces.

Yes, there are always crystallized creatures near these crystals, and it's a wonderful feeling, as if the creature will unconsciously eat these crystals, and then the crystals will start to grow on its body in place of its original carapace, and the process may be quite fast.

There is more than one crystallization here, and when the assassin releases the light, he can see that there are all around him, and they are piled up in clusters all over the cavern, giving this damp and dark place a special sense of beauty......

As we move forward, the original stony ground has become gray gravel, and the crystalline clusters have become even larger, and the height of the original stone is only about one meter, but here it is slowly increasing in height, two meters, three meters...... Even Lynn saw that it was more than six meters tall.

But it seems that because of the impermeability here, there are no creatures, and the scorpion of the previous one cannot be seen here.

…… Wait, what's that?

Lynn saw a large object in front of the Assassin troops, the surface of which was also formed by hardened fungi, this one was...... The leg of the head of the plague.

This was only one of the sections, and the predator looked around and saw that he could get into the section, but it was empty, as if he had just made a shell and had not yet stuffed anything into it.

Then Lynn noticed that there were a lot of these one-section legs all around, and some Plague Head Carapace Pieces, could this be the place where the unfinished items were kept?

'Gada'.

As Lynn was inspecting a carapace fragment, she suddenly heard a familiar voice.

When Lin heard this, she immediately asked the assassin to rush in the direction from which the sound came, and sure enough, Lin saw a wonderful thing that she had seen before...... Echo eggs.

Lin had seen a lot of these eggs when she was advancing at sea, and locusts infected by plague fungi would bypass them, and after that, during the war with the fungus on the mainland, Lin had never seen anything like it, but she didn't expect this to be here?

This echo egg is exactly the same as the one I've seen before, wrapped in a layer of rock, and occasionally makes a 'gada' sound, and there are many scattered nearby, but it seems that this one is the only one that makes a sound.

Lynn had the Assassin open a nearby silent echo egg, and when digging through the outer rock, it was discovered that the egg inside was dead.

It seems that the energy is exhausted, and maybe only one can make a sound alive.

Lin continued to move on, there were many echo eggs here, most of them were close to the crystal cluster, but only the one that Lin saw at first had a sound, and all of them were dead.

This underwater cave seems to be hiding quite a bit of stuff, and Lynn thinks she might be able to discover the history of the fungus here.

Now, Lynn's troops suddenly stepped into a clearing, and the edges of this clearing were filled with crystals and echo eggs, as if they had been pushed to this position by some creature, specifically to clear the clearing.

In front of her, Lin suddenly saw a bunch of echo eggs forming a circle, and in the center of the circle, there was a huge crystal, this crystal was about ten meters high and more than five meters wide, like a huge rock, and there seemed to be a ...... in it What is it.

The location was not clear, and the assassins looked closer, and through the transparent crystal surface, Lynn noticed that there was indeed a strangely shaped piece in the center of the crystal.

The thing was gray, it seemed to be very soft, and its shape was very irregular, and the whole thing was about two meters in size, like a lump of flesh or something, and it was still trembling slightly, as if it was still alive.

Lynn also noticed that the piece of meat was surrounded by a number of mycelium-like threads, which were connected to the bottom of the crystal, as if they were leading to the ground.

Is this ...... The brain of the plague fungus?

Lin felt that it was indeed releasing a large number of signals, which were much stronger than those of the previous Fungal Lord, but because it was underground, Lynn thought that it was impossible for its signal to be transmitted to the plague army outside, so did she need the Fungal Lord as a 'transit station'?

This brain seems to be quite large, but the plague fungus can only occasionally show intelligence, and it is really necessary to study it.

The Assassins began to climb the crystal, but just as they were touching it, Lynn heard the nearby sand suddenly begin to vibrate violently, as if something was about to emerge from the gravel. (To be continued......)
