The radiation background of the magic barrier not only interferes with prophecy spells, not only prohibits teleportation spells, but also interferes with "magic detection", and even creates a noise background that interferes with the auditory perception of living creatures.

At this moment, Isaac discovered that it also directly interfered with the aura radiation of the "magic items" with strong chaotic radiation, making it difficult to directly identify the attributes and qualities of the "magic items".

From this, Isaac's heart just moved, and he was contacted again. It also has related "magic effects" and even "magic traps"!

In this kind of "dungeon" environment, not only is it dark, but there are also unknown levels of evil monsters lurking, and there are also all kinds of interference from this "chaotic radiation"...

"really!"

"This is not only a place where adventurers become famous, but it is also the most dangerous tomb of heroes in the material world!"

"In this kind of environment... normal spell casters, I'm afraid only lichs and the like can adapt to it!"

After all, the lich's various immunities are inherently restrained from "sneak attacks".

This further discovery.

Isaac was on heightened alert for a while.

Of course... the high expectations in my heart inevitably made my interest even higher.

People who don't know how to do it think this is a "mysterious barrier"!

Standing at his level...the essence of this magic barrier is no less inferior to the "mysterious lock"!

This is, if you can gain something, it is definitely worth it!

And that's when Isaac stopped and turned his eyes.

Just as they were sneaking towards this side with great vigilance, a team of three adventurers suddenly stopped.

Anyone who dares to venture into the Lost City must be well prepared.

Not to mention anything else, a rare item with "dark vision" is a must-have for everyone.

Isaac looked towards them, and they suddenly noticed the outline of the figure in front of them.

Another faint firelight flickered in the darkness of the corridor.

Just by the light of this fire, among the three of them, the adventurer, who was wearing night vision lenses and always had a long bow in his hand, with a bit of half-elf characteristics, suddenly shrank his eyes.

He recognized the person in front of him!

It is the "Shangjin" lady who must be greeted respectfully. She alone is the one who dares to break into the Lost City of Earth!

The long arrow had already been strung, but it was not raised directly over there. It was half-pointed towards the ground. The half-elf adventurer cautiously signaled his companions to stop, while calmly saying: "Sir, would you please go first?"

On the dungeon level, the long corridors are like a maze, with countless side roads.

If you miss this journey, you will have your own destination.

But he didn't want to have a fatal conflict with an unknown person whose danger level was hard to say because of a misunderstanding.

Of course, if you don’t want conflict or don’t want conflict, you just have to be careful when it comes to it.

These three people.

Isaac glanced over.

The half-elf who spoke must have the title of "Ranger", and may have advanced to "Magic Archer". After all... Even if the magic aura is interfered with by chaotic radiation, from the appearance of his longbow,

It can be seen that it is not an ordinary product, and judging from the fact that when he met here, he was focused on the bow and arrow, but did not move the long sword behind his back, it is obvious that the bow and arrow is his main weapon!

The other two people.

One is a dwarf. The heavy armor, the heavy axe, and the heavy shield are naturally the consistent style of the dwarves. Most of the footsteps that penetrated the noise before were also made by him.

And the last one, judging from the robe, wand, and other equipment, is obviously a spell caster.

These three people were alert but also reserved. No matter whether it was weapons or spells, they were not pointed directly at them.

This is... trying to be on guard as much as possible without conveying any hostility!

"good!"

Isaac has always been reasonable.

With this gesture over there, he nodded slightly, but continued to move forward.

Seeing this, the three people breathed a sigh of relief and were not in a hurry to follow. They counted the time and waited until the darkness completely disappeared before slowly starting to move again.

And the front.

It was Isaac who was walking in the darkness, casting spells silently.

And when his spells cast, the magic power fluctuations were obscured by chaotic radiation.

It would hardly alarm any creature. After a full minute of casting time, as he raised his hand, a total of thirty numbers, half real, half illusory, like eyeball-shaped "beads", appeared in the sky.

It suddenly appeared among them.

"Go, scout the way and be on guard for me!"

As soon as the mind and will moved, these "eyeballs" immediately rose to the ceiling, and fell to the corners of the corridor, and quickly dispersed and distanced themselves.

And as they spread out.

Although they cannot share their vision directly, their faint telepathy will alert him immediately if there is any situation anywhere!

This is the sixth-level spell "Arcane Eye"!

It is a stronger version based on the fifth-level prophecy spell "Peeping Magic Eye"!

"Arcane Eyes", the caster can create a large number of "Arcane Eyes" to observe and monitor everything within a mile centered on himself.

Moreover, unlike the "Peeping Magic Eye", the observation of the "Arcane Magic Eye" can penetrate normal darkness.

In addition, the number of creations is linked to the level of the caster. With Isaac's 19th level mage level and 9th level "mana enhancement", he can create 29-32 "arcane spells".

Eyes"!

And, more importantly, the duration of the "Arcane Eye" is also related to the caster level, and can last for one hour per caster level.

In other words... this spell casting, with Isaac's spell strength, lasts for more than a whole day!

This is exactly what Isaac prepared specifically for this after having a certain amount of information about the environment of Leyline City.

This kind of creative "detection spell" is the only type of prophecy spell that is not affected by the radiation background of "Leyline Maze"!

The scattering of these thirty arcane eyes...

Even though his spiritual perception was interfered by the radiation background of the magic barrier, Isaac's grasp of the surrounding environment suddenly increased.

"The entrance to the 'Arcane Chamber' on the second floor is in the west direction."

"The map data shows the famous places, which are also in the western region..."

"library!"

"Throne of the Dead!"

"Magic Pillar Hall!"

The names of several landmarks emerged in Isaac's mind.

There is no rush to conduct direct research on the magic barrier in this passage right away.

The mad mage's masterpiece has not been destroyed by anyone for thousands of years.

Even Isaac has enough confidence in his own intelligence and his ability to know magic.

But he is not so arrogant that he thinks he can analyze and reverse the most famous achievement of the Mad Mage at will!

In particular, the time he can stay here will not be too long!

still……

"We should first look for the magical secret room directly related to Halaster, and then analyze it through combination and comparison!"

"The dungeon level is the most likely to be relevant..."

In the darkness, Isaac roughly grasped the direction and walked through the passages that forked from time to time, but the speed of his footsteps remained consistent.

Not much time.

There are still whining noises wafting through the passage.

Suddenly, the induction that was transmitted to his soul made his heart move, and he kept moving forward. At a very fast speed, an "Arcane Eye" flew back, and as he stretched out his hand, it fell on him.

of palm.

Immediately, some images quickly appeared in his mind.

"Scavengers and goblins, and hobgoblin warriors."

"What's on the top of the cave is a dormant pseudo-monster."

"However, this kind of environment..."

In the image, at the end of this long corridor, there is an "Arcane Eye" that has not been completely observed, but it can be roughly seen that the scale is quite large.

On one side were the beast-turned-ratmen, and on the other side were the goblin tribe led by the hobgoblin, engaged in a bloody fight.

And lurking in the shadows of the ceiling of this hall, there are several dormant pseudo-monsters, just waiting for a big meal.
