"It's better to start setting up the secret room outside this barrier!"

After thinking for a moment, Isaac quickly made a decision.

Although the changing form of the "Green Dragon Crown", the Enchanting Demon's eye of true knowledge may not be able to see through it.

However, he still has many magical effects on his body, which may not be able to hide from the Tanar'ri giants, including the Enchantress.

Moreover, he had already made preparations to create a magical secret room.

Penetrating this secret room from outside the barrier to inside the barrier not only facilitates his in-depth research on the seal barrier, but also provides the convenience of being able to enter and exit the Hell Gate Castle at any time!

With this decision, Isaac further thought about some of the structural introduction of Al-Almo to Hell Gate Castle.

"Hell Gate Castle has at least nine floors!"

"Although the true north-south tunnel has only one core passage."

"However, between the layers, whether vertically or horizontally, there is a network of caves that are difficult to accurately count and are like a maze."

According to Anice's information, these cave networks are composed of the Esko Cape, even the elven civilization of the older era, those tombs, mausoleums, and even magical ruins. However, more importantly, they are still the tower.

After the Tanari ruled the city, the high tanari drove many low-level demons and later demons to dig it out.

These are called "deep dark caves", and there are also unknown numbers of monsters inside.

Although the vast majority of them are "waste demons" who cannot join the "Flash Legion", such as "coward demons" who can only be used as "slave miners", and "original demons" who are even weaker than "coward demons",

There are also goblins and the like, who are worse than the original demons, dregs among dregs.

But it's not that there aren't any creatures who hide in it because they don't want to obey Tanar'ri's orders. There are even many spellcasters here.

According to Anis, there are rumors from some high-ranking members of the demon tribe. Among these spellcasters, there were even those who were in the Esko period. They summoned the tanar'ri, but they were simply overthrown by the tanar'ri. They could only

The old guy who survived in the form of a "lich"!

"If these old guys can survive, it's obviously not because of Greensack's extrajudicial mercy!"

"Most likely, some of the 'deep dark caves' are not only hidden, but may even penetrate the 'sealing barrier', which makes Greensack and the others unable to follow and search even if they have the 'Eye of True Knowledge'!

"

"And if these Tanar'ri giants can't search directly..."

In Isaac's mind, he quickly became sure of the specific layout of the secret room.

"Creating a 'deep dark cave' directly would naturally require a large amount of work. Even if it is to 'turn fossils into sand', I don't know how long it will take to complete."

"However, if there is a ready-made target and you can connect to it directly..."

"All we need to do is arrange some illusion scenes and add some combination of 'disgusting' and 'suggestion', so that those who approach will not feel any abnormality and will consciously turn around!"

And such an arrangement...

Isaac is still confident that it is impossible for those Tanar'ri giants, ordinary demons, and ordinary demons to see through his arrangement even if they are close to his secret room!

With such a move in my heart, a "short message" was transmitted silently from my heart.

It was in the distance that the military camp fortress was like a dungeon in the dark space. While stirring up a few Tanarok, the Al-Al Demon was waiting patiently. He only said a few words calmly and ended the fight with these demons.

The topic of orcs quickly went into the depths of the fortress.

…

Half a day later.

A dark cave located on the level above the underground military camp.

First, by combining "fossils into sand" and "turning sand into stone", a secret room connected to this cave was quickly formed.

From within the dark cave, there was quite a certain range of space, some long-lasting illusions, and a magic circle to cover up the magic aura and magic fluctuations, and they were quickly arranged.

"That's it for now!"

"Take this side and combine it with the secret room on the other side of the tunnel sentry post."

"While researching, bring the Elf Holy Sword here."

"If you want to truly enter Hell Gate Castle, then put the Holy Sword over there."

Although the environment of this secret room is simple, Isaac has never had any high aspirations for the environment. If it can meet his research needs, it is enough.

As for whether this place can meet his needs...

His eyes were slightly squinted, and in the depths of his pupils, a circle of light was looming.

The combination of true knowledge, mind and will, and the essence of the "Wheel of Heaven"...

At this moment, in front of him, although it was invisible, it could be felt. It was different from the "Earthline Maze City Barrier", but it was also...

"Legendary spell!?"

"However, it seems there are some differences!"

"Is it a mythical lock?"

"Or……"

A hand was raised, caressing the invisible barrier. The barrier seemed to not exist at all. There was no feeling of touch from his hand.

However, although it cannot be directly touched with the material body, Isaac's unfolded mind and the essence of the "Wheel of Heaven" have been connected from the outside to the inside. At the same time, from the level of the phenomenon of magic and the essence of magic,

By comparison, I observed and analyzed this boundary.

This observation…

“What an artistic construction!”

"The forcing effect on the High Tanari and the prohibition on teleportation are woven together like a web."

"But it is bound to the Mysterious City of Hellastna. It has an obviously different nature."

"Probably, it's the style of those with pointed ears!"

"However, when the Harper sealed this place, there seemed to be no rumors of the Elf Supreme Mage appearing during that period."

"Is it... a great mage like Kelben who has profound research on the supreme magic of elves?"

After a long period of time, Isaac came back to his senses with some admiration and some speculation from this observation.

This chapter is not finished yet. Please click on the next page to continue reading the exciting content! Although I have only identified some effects of this enchantment from some understanding, there are more and deeper essences that have yet to be explored slowly.

Analyze.

However, after observing for a while, he had a vague feeling.

This enchantment has an elven style and is quite similar to legendary spells.

but……

It seemed to be somewhat different from the "legendary spell" he knew.

At the same time, it seemed that there were some differences from the "Mysterious Barrier" he knew.

After pondering in his mind for a long time, Isaac finally stopped these thoughts.

A bolt of lightning flashed on him immediately.

He was going to get the "Elven Holy Sword" earlier, but a slight observation made his thoughts sink deeply into it.

Of course, the more this happened, the more excited he became.

He has already seen and analyzed the "Line Maze Barrier" in depth, and he will be involuntarily attracted to the point of being deeply trapped... This is the only way to see the extraordinary degree of this "Seal Barrier"!

There was a flash of lightning and the figure disappeared immediately.

But after just a few breaths, another bolt of lightning broke through the darkness of the secret room.

When the electric light disappeared, there was a faint purple glow, burning like a candle in the secret room.

Of course it is the Elf Holy Sword!

Just like before, when the holy sword was once again in Isaac's hands, the shock and struggle began again.

One of Isaac's hands also naturally passed over its blade.

The lightning flashed immediately.

"Suspected to be the enchantment of the elves' supreme magic!"

"The Elf Holy Sword that can penetrate the barrier and completely erase the life essence sealed by Greensack!"

"Let's see if, by combining you, we can compare some of the essence of the elves' supreme magic!"

In Isaac's eyes, the wheel of light projected from the soul's essence shone exceptionally brightly at this moment.

The gaze, the observation of the sealing barrier, and the observation of the Elf Holy Sword, especially the magic gem on the Holy Sword...

The mind and will are slowly surging.

However, just when his will touched the purple flame of the Elf Holy Sword...

There was another purple electric light, more intense than touching the sword blade with one's own hands, and it struck the soul directly.

Even though Isaac had been touched and electrocuted several times, his eyes were still slightly narrowed as his heart was shaken involuntarily.
To be continued...
