"This ...... This is?"

Mage Envia felt a huge burst of coercion, and felt as if he was out of breath all over his body, which was obviously very different from the first four layers.

The white light gradually dissipated, and in mid-air, a grizzly bear more than three people tall appeared, but the important thing was not how large the grizzly bear was and how terrifying the momentum was, but the dense runes that constantly surrounded the surface of the grizzly bear's body.

Those runes flew out from the vermilion stone pillar to enhance the strength of the guardian spirit, and this grizzly bear was far more powerful than the guardian spirit of the fourth layer just by looking at the momentum.

What's more, there is also the protection of that layer of runes, which is very difficult.

"Sure enough, the strength of the fifth-layer guardian spirit has changed drastically!"

Merlin's eyes narrowed slightly, and the guardian spirit of the fifth layer actually made him feel a trace of threat, which showed that it was likely that the grizzly bear could hurt Merlin.

With Merlin's current strength, he can be compared to a sixth-level peak spellcaster, but now, he feels a hint of threat in the fifth-layer guardian spirit, which shows that this fifth-layer guardian spirit is extraordinary.

The fifth layer is the real test of the Rune Tower! It is no wonder that in the history of thousands of years, there are very few people who can break through the fifth layer.

Mage Envia glanced at each other and the other two mages, and then said in a low voice: "Don't be afraid, the Koleman Rune Array, if played properly, can even be comparable to a sixth-level spellcaster, the three of us have studied the runes very deeply, and we will definitely be able to exert most of the power of the Koleman Rune Array, and at least reach the peak of the fifth-level spell." I'm sure I'll make it through the fifth floor!"

The voice fell. Mage Nwia was the first to charge towards the grizzly bear. The Koleman Rune Disc in his hand exuded a trace of dazzling light, and a large number of runes began to bless his body, making his aura quickly become powerful.

At the same time, the remaining Mage Sarah and Mage Yilman also glanced at each other and started together.

The Koleman Rune Circle originally required at least three people to exert its power. The three of them had studied the runes together very deeply, and they were able to exert most of the power of the Koleman Rune Circle, reaching a point comparable to that of a fifth-level spellcaster.

"Boom".

Lightning suddenly appeared, like a heavy rain pouring, pouring down in an instant, blasting towards the grizzly bear in mid-air, the Koleman rune array is a purely offensive rune array, if it can exert its maximum power, it can even bombard the sixth-level spellcaster.

But with the power of Mage Enwia and the other three. Now it can only exert part of the power of the Koleman Rune Circle, but even so. It is also comparable to a fifth-level peak spellcaster.

"Crackling".

One after another, thunder and lightning hit the grizzly bear's body one after another, but the layer of mysterious runes on the grizzly bear's body, like a real armored robe, blocked the thunder and lightning outside, and no matter how thunder and lightning bombarded, it could not cause any harm to the grizzly bear.

"Come again!"

Master Envia gritted his teeth, he was originally full of confidence, and it took a huge price to get the Koleman Rune Disk, just to be able to break through the sixth layer and get the treasure left by Archmage Fidel in the sixth layer.

It's just that now that he has been stopped on the fifth layer, how can Master Enwia be willing?

"Buzz".

The Mage Ilman and Mage Sarah that Mage Enwia is looking for are the best at runes that he can find among the spellcasters below the fourth level of the Dark Spirit Realm, and only with them can he barely urge the Koleman Rune Circle and exert the power of the rune circle part.

As the three of them desperately urged the rune array, finally, from within the Koleman rune disk, several huge runes with white brilliance appeared loomingly.

As soon as these runes appeared, the thunder and lightning as thick as a finger disappeared, and was replaced by a thunderbolt as thick as an arm, constantly spitting lightning, which was daunting.

Seeing this thick thunderbolt, a hint of joy appeared on the face of the Enwia mage, and he said in a deep voice: "The strongest attack of the Koleman Rune Array, Koleman's Thunder, kill!"

The Koleman Rune Circle is named after a great spellcaster, Koleman, and it is rumored that the Koleman Circle can be activated by up to eighteen Thunder Archmages, of course, these archmages must be proficient in runes.

With eighteen archmages, urging the Koleman Rune Circle together can make the Koleman Rune Array exert its strongest power, and even faintly be able to compete with the legendary mage.

But this is just a legend, the legendary mage is a great spellcaster who has condensed the law and mastered the true meaning of the elements, no matter how powerful the spell is, it must follow the law and be suppressed by the power of the law.

Therefore, the caster below the legend, no matter how strong he is, cannot be stronger than the legendary caster, even in the most glorious era of the caster, I have never heard of someone who can kill the legendary mage without the realm of legend!

Although regarding the Koleman Rune Circle, it only takes to gather eighteen Thunder Archmages who are proficient in runes to rely on the power of the circle to compete with legendary mages, but this is just a legend.

The only thing that can be explained is that the Koleman Rune Circle is indeed extraordinary, and it is not simple.

The Koleman Rune Disk in Master Envia's hand was just that the Koleman Rune Array had shrunk countless times, and of course, the power had also been reduced countless times, but even so, when the huge Koleman Thunder appeared, it still made people feel the palpitations in the heart of the Fa Sense.

"Boom".

The thunder of Koleman, which was as thick as an arm, flashed like a dazzling lightning, and then came to the grizzly bear in mid-air and bombarded it fiercely.

The loud noise, coupled with the flickering of electric light, made it impossible to see inside.

Merlin was also a little shocked by the power that the three of them could exert after joining forces.

These three people are obviously only third-level spellcasters, although they are all the best in the dark spirit realm, and it is very likely that they will become fourth-level spellcasters and build towers alone.

However, these three people did not have Pandora's magic ability, they did not have powerful spell-casting tools, and just relying on a rune magic disk, they could instantly exert the power of a fifth-level peak spellcaster, which also made Merlin have a deeper fear of runes.

In the most glorious era of spellcasters, with powerful runes in their hands, even a weak spellcaster can bombard high-level spellcasters.

Runes are indistinguishable from spell construction, as well as Pandora's magic energy, but today, there are too few spellcasters who understand rune literature.

After all, runes are no better than Pandora's magical energy, and they only need to gather some treasures to successfully cultivate and burst out with unparalleled power. Rune literature takes a long time and a lot of energy to study carefully in order to master a little bit of the skin, as for mastery, unless you have a good inheritance, coupled with extraordinary talent for runes, you can become a great rune master.

Just like Merlin, there is a rune spell disk, but he is not proficient in runes, so he can't urge the rune spell disk, even if he is a seventh-level spellcaster, Master Bamu, is already a high-level spellcaster, but it is also because he is not proficient in rune literature, and he can't urge the rune magic disk.

If you are not proficient in runes, even if you get a powerful rune magic disk, it will not help, and it will not help your own strength, perhaps, this is also one of the reasons for the gradual decline of rune literature.

Of course, the rune circle is only one of the vast runes, and it is one of the widely used runes, and there are many ways to apply runes.

Like the guardian spirit in the rune tower, it is obviously born in a complex rune array, but it has the breath of life, and for example, the spirit of the rune circle in the dark spirit realm, the black cat Didemos in the stone tablet outside also has the breath of life, which is very magical.

These are just one of the aspects of the application of runes, being able to give birth to life from nothingness, even legendary mages can't do it, but if you are proficient in runes and reach the same level as Archmage Fidel at the beginning, you can give birth to life from nothingness.

Archmage Fidel left this rune tower alone in order to find those who are talented spellcasters, especially those who are good at runes, so that up to three casters are allowed to unite and set up powerful rune circles.

Now the three of them, Master Enwia and the others, are using the rune disk to stimulate the power of the Koleman rune circle in the magic disk, and fight against the guardian spirit grizzly bear of the fifth layer.

The thick Coleman's thunder, filled with a trace of electric light, enveloped the huge body of the grizzly bear, and only a burst of "crackling" sound could be heard, and no one could see the situation inside.

"Roar ......".

Suddenly, a huge roar sounded, and a violent shock wave directly shook the three of them, including Master Envia, and turned pale.

And as this roar sounded, the electric light shrouded in the grizzly bear also collapsed one after another, revealing the grizzly bear's body at the end.

At this time, the grizzly bear still looked energetic, and the mysterious rune armor on its body seemed to be much less, and it looked a little dim, and it was obvious that it was blasted off by the Koleman Thunder cast by Master Envia just now.

However, it was only a few runes that protected the grizzly bear, and the grizzly bear did not suffer any damage.

"How can you be unscathed? How can you be defeated?"

"Defeated, completely defeated, even the thunder of Koleman can't bombard the guardian spirit, we are completely defeated......"

"It's too much to underestimate the Rune Tower......"

Master Envia and the other three were pale, and their faces showed disappointment, they thought that with the help of the Koleman Rune Disk, the three of them would be able to easily break through the fifth layer, and even have a chance to break through the sixth layer.

But the current situation made them deeply realize that in the thousands of years of the Dark Spirit Realm, there were very few spellcasters who could break through the fifth layer.

The fifth-level guardian spirit is far from being as simple as a fifth-level spellcaster!(To be continued......
