My queen is rebelling!

Seeing the faintly glowing lines, Cohen breathed a sigh of relief; the thing was still there.

He said to the others:

"This is the crystallization of the arcane empire's wisdom, an auxiliary spell that can communicate with all intelligent beings—the 'Concentric Seal'!"

"The 'Concentric Seal' is divided into a primary seal and a secondary seal.

The primary seal can unilaterally enable or disable the communication function of the secondary seal."

Witnessing the miracle from the history of human civilization across a thousand years, excitement flickered on everyone's faces.

The dragon mark on Cohen's hand shimmered, and a sharp carving knife appeared.

He walked to the mural, first cleaning the dust and debris around the glowing lines.

Then, he carefully studied the structure of the seal and its connection points with the mural, cautiously peeling it off.

After a long time and meticulous operation, Cohen finally removed the two faintly glowing seals intact.

Subsequently, he handed the seals to Nephthys.

Nephthys had already prepared two blank scrolls. After receiving the seals, she began to meticulously copy them onto the scrolls.

Cohen took this opportunity to say to Asuna:

"Asuna, after we return, contact the 'Pale Wings' and purchase some materials for inscribing seals.

Also, from now on, you will be our 'Endless Blade's' external liaison.

Arnold frowned slightly:

"So many beastmen, do I have to engrave them all by myself?

Can't we recruit some seal inscribers?"

Cohen shook his head:

"Not yet. The engraving method of the 'Concentric Seal' cannot be leaked."

In his previous life, Arnold had hired some seal inscribers, which led to the rapid leakage of the 'Concentric Seal'.

Cohen learned from Arnold's mistakes, preferring to put in more effort rather than let this secret be made public so quickly.

Otherwise, with Cohen's current strength, he wouldn't have the confidence to compete with those empires and kingdoms for beastman slaves.

He said to Arnold:

"You don't have to do it all by yourself.

The secondary seal is relatively simple. You can first link a few beastmen with the 'Concentric Seal'.

Then teach these beastmen how to inscribe, and you can work together to speed things up."

Arnold nodded thoughtfully.

The lines of the 'Concentric Seal' were extremely complex and profound. Each stroke of copying consumed a great deal of energy.

Time slowly passed. Finally, after about half the night, Nephthys completed the replication of the two seals.

Putting away the original seal and the copied seal, Cohen was in a great mood.

Having completed the main task of this expedition, the next step was to find that demigod-level artifact.

Relying on the star map position he had remembered in the Nightmare Mist Illusion, Cohen headed towards the location where the 'Book of Time and Space' was stored.

The research institute had crashed, and the space array was forcibly shut down.

Unable to teleport through various space nodes, he could only travel on foot.

Fortunately, although the research institute had crashed, the main structure was still relatively solid, and its location could still be vaguely distinguished.

After walking for a while and turning a corner, a narrow tunnel appeared in front of him, only wide enough for one person to pass through.

Cohen recalled that the room containing the 'Book of Time and Space' was near here.

Cohen stopped and said to the others:

"It's not easy to pass through ahead. I'll go in and take a look first. You guys wait here."

Cohen squeezed into the narrow entrance sideways.

The tunnel was filled with a decaying and damp atmosphere, and faint emerald-green liquid seeped from the walls on both sides.

Cohen sensed it slightly and found that it actually contained a trace of extremely weak life element.

A gleam flashed in Cohen's eyes, and he quickly discovered that this emerald-green liquid was very similar to the juice of the elven race's famous healing elixir, the 'Elven Holy Fruit'.

Cohen secretly noted the discovery in his heart and continued forward.

It was as if he had entered a huge maze, which made Cohen couldn't help but mutter to himself.

In his impression, this ruin shouldn't have such a long tunnel, and this tunnel was extremely irregular, not like something artificially excavated.

As he continued to move forward, the tunnel became more and more intricate, and the entire space became smaller and smaller.

Cohen had to almost bend over to continue moving forward.

Before long, it suddenly opened up.

Cohen came to a spherical cave.

Looking at this spherical cave, Cohen had a faint sense of familiarity.

Suddenly, he heard a strange sound, like a whisper coming from afar.

The sound was getting closer and closer, obviously coming towards Cohen's direction.

There are still living creatures?

Cohen's eyes flickered, and the Ghost Crab on his feet activated, directly遁入 into the wall next to him.

The sound grew louder and louder, turning into a rustling sound coming from all directions.

Soon, the ground and the surrounding walls of the cave seemed to be covered with a layer of emerald-green curtain.

Cohen fixed his eyes and saw a large group of emerald-green worms surging from the opposite side like a tide.

These worms were slender like silk, wriggling their bodies, as if flexible threads were dancing in the air.

They were densely packed together, and the sheer number of them made one's scalp tingle.

As they approached, the rustling sound grew louder and louder, like the murmur before a storm.

Wherever they passed, the ground seemed to be trembling slightly.

After a few minutes, it seemed that no more worms were coming out of the distant tunnel.

Then, these countless tiny worms began to gather like surging tides.

They wriggled their soft bodies, intertwined and climbed over each other. Those seemingly insignificant little worms were now being pulled by a mysterious force.

They adhered closely together, connecting section by section.

Each little worm was trying to find its place, constantly adjusting its posture.

Gradually, a huge worm outline began to appear.

As the last little worm joined, the large worm composed of little worms became clearer.

Its body was huge and shocking, and its surface was constantly wriggling, as if it had its own life rhythm.

Countless little worms, like individual cells, jointly formed this amazing and bizarre creature.

The bizarre creature moved slowly, and the ground trembled slightly under its weight, emitting a chilling aura.

Looking at the huge and bizarre creature, a forbidden name floated into Cohen's mind—

Nether Abyss Worm!

Cohen suddenly felt his scalp go numb.

He really couldn't understand why this forbidden creature would appear in the main plane!

Fortunately, it was only emerald-green. If it were a golden worm demon, he would definitely turn around and run into the shadows without saying a word.

This was the most terrifying creature from the depths of the Netherworld Abyss, a Nether Abyss Worm that could devour even the legendary realm of a legendary-tier transcendent in its mature stage!

Nether Abyss Worms are said to be the sin worms exiled to the Netherworld by Sarah Louis, the ancestor of all worms, used to devour the souls of the fallen and banished in the Netherworld.

They can devour everything. In their juvenile stage, they are emerald-green and can devour most solid metals.

Even a legendary-tier magic weapon can be eaten away by them if given time.

The mature stage is bright golden and can devour the legendary realm of a legendary-tier transcendent!

There is also a metamorphic stage that only exists in legends, which is said to be able to bite off a piece of even a saint's sanctuary!

It is definitely a forbidden existence in the entire main plane.

Nether Abyss Worms generally live in the Netherworld Abyss, above which there are layers of enchantment and plane barriers, and under normal circumstances, they cannot come out at all.

Cohen really couldn't figure out why there would be a juvenile Nether Abyss Worm here.

Just as his thoughts were drifting, suddenly, a faint silver light lit up not far away, vaguely showing the outline of a book.

Feeling the fleeting spatial fluctuation, Cohen instantly understood everything.

He shuttled through the walls, running towards the place where the silver light was flashing.

By the time Cohen arrived, the silver light had gone out.

A simple and dilapidated book lay quietly on the ground.

The cover was old and mottled, as if it had experienced countless storms and vicissitudes.

Cohen took a deep breath, and taking advantage of the worm demon's inattention, instantly put the book into the "Eternal Heart".

Leaving along the wall, he arrived at a safe area away from the worm demon.

Cohen took out the book and gently opened the cover. A mysterious aura rushed towards him.

Strange lights flickered faintly on the pages.

That was the aura of the space array surging!

It was indeed the "Book of Time and Space"!

Looking at the dilapidated book in front of him, it was hard to associate it with the crystal book he had seen in the Nightmare Mist Illusion before.

But in fact, this was the demigod-level artifact, the Book of Time and Space.

Cohen gently touched the pages and could feel a faint energy fluctuation, which was the power of the space array responding.

It seemed to be telling the story of a distant time and space.

This demigod-level artifact, which had witnessed the rise and glory of the empire, was now like its empire.

Having lost all its glory and halo, it lay quietly in the ruins, unseen by the light of day.

Cohen recited the spell taught to him by the gray-robed researcher.

Soon, a strange and mysterious rune began to appear on the first yellowed page.

As the magic power in Cohen's hand was input, the rune seemed to come alive.

The lines of the rune were like winding black snakes, twisting and entwining in the void, sometimes intertwining together to form complex shapes, and sometimes dispersing, as if exploring an unknown space.

The edges of the rune were covered with sharp protrusions and jagged lines, as if warning any creature that dared to approach, filled with a dangerous and strange aura.

Seeing this mysterious rune, Cohen finally confirmed the origin of that Nether Abyss Worm!

It had actually sneaked over from the depths of the Netherworld through the spatial node on the "Book of Time and Space."

This rune represents the Netherworld Abyss.

Cohen speculated that something must have happened to the "Book of Time and Space," causing the teleportation channel to the Netherworld Abyss to open.

It just so happened that a young Nether Abyss Worm was passing by and was teleported over.

Then, the energy of the "Book of Time and Space" was exhausted, and the worm could no longer return.

Cohen was secretly shocked. The people of the Arcane Empire were indeed a bunch of lunatics, daring to imprint the spatial node of the Netherworld Abyss on the "Book of Time and Space."

I wonder how they got in.

Cohen continued to flip through the book, discovering that he could only turn two more pages.

No matter how much magic Cohen channeled, no runes representing spatial nodes appeared on these two pages.

This indicated that these two pages were blank. As long as a spatial node of a certain place was imprinted, the "Book of Time and Space" could be used to travel back and forth.

It could teleport a hundred people at a time, but judging from the current degree of damage, it would be difficult to even teleport one person.

According to that gray-robed researcher, the complete "Book of Time and Space" had a hundred pages, forty pages had been used, and sixty pages were blank.

Now they are all damaged, and only this one page with the spatial node leading to the Netherworld Abyss can be used.

Understanding the key to this, Cohen stared intently at the Nether Abyss Worm in the distance.

A homeless Nether Abyss Worm. Cohen immediately had an idea about it.

An emerald green worm, belonging to the juvenile stage.

The juvenile "Nether Abyss Worm" itself is not that aggressive, but it can slowly devour various metals and rare materials.

Cohen looked at the empty spherical cave and finally understood where that familiar feeling came from.

The cave in front of him was actually the research room in the Nightmare Mist Illusion where the "Book of Time and Space" was stored.

The things in the research room should have been devoured by this "Nether Abyss Worm."

No wonder it's empty here.

Could it be that it also ate the corpses?

Cohen shook his head and overturned this guess.

According to records, "Nether Abyss Worms" do not eat blood.

Looking at the "Nether Abyss Worm" slowly moving its body not far away, Cohen closed the "Book of Time and Space."

He still remembered what the gray-robed researcher said, that the cover of this "Book of Time and Space" sealed a small sub-dimension.

It's just that the rules are not perfect enough, the space is not very stable, and humans cannot survive.

Then can this "Nether Abyss Worm" survive on it?

The environment of the Netherworld Abyss should not be better than a chaotic small sub-dimension.

Perhaps it's worth a try.

Cohen stepped out of the wall, and the "Nether Abyss Worm" not far away saw a strange creature appear.

Its whole body began to surge with emerald light, which was a sign of anger.

Cohen focused his gaze, held the "Book of Time and Space," and chanted a spell.

Ancient lines began to spread on the cover, like a beating pulse, and a mysterious power seemed to be about to emerge.

Cohen raised the "Book of Time and Space" high, and a dazzling light instantly shot up from the cover, illuminating the entire cave.

The ancient lines were like activated circuits, and mysterious light flowed rapidly within them.

Immediately afterwards, a virtual vortex gradually formed above the cover.

Looking at the "Nether Abyss Worm" trying to escape, Cohen accelerated the output of magic power, and the vortex instantly doubled in size, and a powerful suction force erupted from it.

Like an invisible big hand, it firmly grasped the "Nether Abyss Worm" and pulled it into the vortex little by little.

As the worm was taken in, the vortex gradually shrank and finally disappeared.

Cohen looked at the "Book of Time and Space," the cover completely returned to calm, as if nothing had happened.

Cohen breathed a sigh of relief, his eyes were tired, but he couldn't hide his excitement.

This time, the harvest was bigger than expected.

In addition to the demigod "Book of Time and Space," the "Nether Abyss Worm" was also an unexpected surprise.

Next, he needs to collect some information about the "Nether Abyss Worm."

Even he knew very little about the detailed situation of the "Nether Abyss Worm."

Moreover, it is not easy to sign a master-servant contract with a creature from the Netherworld Abyss.

Cohen restrained his thoughts, waved his fingers, and chanted a spell.

The "Book of Time and Space" gradually shrank, and finally turned into a rune imprinted on his arm.

The rune was obviously much more incomplete than when the gray-robed researcher received it.

He had to find a way to repair it as soon as possible. To enter the ancient tomb below, which Windsor Deller called the "Sleeping Cave," the "Book of Time and Space" was an indispensable item.

The gray-robed researcher had told him how to repair it.

But this kind of thing must be done in secret. Didn't "Black Tomb" spend so much money for Isabella's one-fifth demigod "Wings of Gold?"

If others knew that Cohen had the "Book of Time and Space," Effiein would probably be uprooted.

The resources required to repair a demigod are definitely sky-high.

He has to find a sucker to pay the bill.

It seems that His Excellency the Special Envoy is particularly enthusiastic about this "Sleeping Cave." Cohen had an idea and came up with a plan.

After solving the matter here, Cohen returned the same way.

The others breathed a sigh of relief when they saw Cohen return safe and sound.

Cohen said with a smile:

"This time the harvest was not small, I've kept everyone waiting."

Cohen estimated the time, and it was still early before the appointment with Windsor Deller.

He thought of his Queen sister's hobby, magic arrays!

Cohen vaguely remembered that there was a notebook of an Arcane Empire array master inside, but he didn't know if it was damaged.

The Queen sister's twenty-sixth birthday is not far away, and a notebook containing the essence of ancient arrays would definitely be a perfect birthday gift.

Cohen followed his memory, turned around several corners, and stepped into an old storage room.

As soon as he entered the door, the dust of time floated in the air.

Immediately afterwards, a few faint glimmers of light flickered in the room. As the light gradually increased, the ancient lines on the ground also began to show a mysterious color.

Those lines seemed to be alive, slowly flowing with light.

Suddenly, a strong light rose from the center of the ground, and in the light, mysterious symbols and patterns continued to change, emitting a powerful magic power.

A magic array!

However, to Cohen's surprise, this magic array did not seem to have any attack power.

As time passed, the light converged into a beam of light, projected on the ancient wall, and jumped back and forth in a specific trajectory, as if telling a story of the past.

Cohen's eyes moved slightly, and he instantly discovered something.

He firmly remembered the trajectory of the light beam in his heart.

Before long, the light dissipated, and the power of the array completely disappeared.

Cohen came to the wall, sensed it carefully, and sure enough, he found something sealed on the surface of the wall.

He focused his eyes, reached out his hand, and began to dance according to the trajectory of the light beam.

Soon, the surrounding space gradually distorted, as if an invisible film was slowly tearing open.

A different-dimensional space array!

Cohen was overjoyed, opened the space array, and an ancient notebook slowly emerged.

The cover had been blurred by the erosion of time, but some mysterious lines could still be seen.

Cohen gently brushed away the dust on the notebook, and at that moment, it seemed to trigger the mechanism of time.

An indescribable sense of solemnity came over him, as if he was holding a piece of history in his hands.

He slowly opened the notebook, and the ancient words were like sleeping elves awakened, and every stroke seemed to contain endless stories and mysterious power.

Looking at the complex patterns and outlined runes above, Cohen was sure that this was a notebook from an array master of the Arcane Empire.

This is definitely a priceless treasure for Yadel, who loves arrays.

With this thing, what benefits should I ask the Queen sister to give me?

Cohen couldn't help but fall into thought.

Until Nephthys woke Cohen up.

Cohen came back to his senses, put away the notebook, and said:

"It's almost time. Presumably, His Excellency the Special Envoy and their group have also finished searching. Let's go and meet them."

Everyone had no objection and followed Cohen back to the gate of the ruins.

When they arrived, Windsor Deller and others had indeed been waiting there for a long time.

Cohen glanced at it and found that the sixth-order adventurer Baron Kulikov looked embarrassed, and the solid and gorgeous armor on his body was already broken.

The eldest son of Duke Gavin, Iffiel, still had a few traces of fear on his face.

Obviously, they had experienced something bad.

Cohen was slightly surprised in his heart. It shouldn't be.

The route he gave them should not have any threats to them.

At most, there were a few silver-level golems. With Windsor Deller, a gold-level, and an experienced adventurer, they should have returned smoothly.

But looking at this, it looked like they had experienced a big battle.

Cohen glanced at Margaret next to him, and the latter winked at Windsor Deller and then shook his head slightly.
