Outside the Rune Tower, all the spellcasters were staring nervously, even Master Leo was no exception, and even some powerful spiritual power fell into the Rune Tower.

After all, there were only a few people who could break through to the sixth layer of the Rune Tower, and in the entire Dark Spirit Domain for thousands of years, including Claes, who betrayed the Dark Spirit Domain.

And now that Merlin has actually broken through to the sixth layer of the Rune Tower, this is an invisible confrontation with the former genius of the Dark Spirit Realm of Claes, and it is no wonder that even those powerful spellcasters will be interested.

It's just that this wait is a long few hours, and Merlin has been on the sixth floor for too long, maybe he doesn't even notice it, but the casters who are waiting outside are a little restless.

"As long as you don't get sent out of the Rune Tower, it means that you still have a chance!"

Mage Leo muttered in a low voice, the blood-colored vertical eyes on his forehead blinking slightly, staring closely at the sixth floor of the Rune Tower, where the light was still shining and showed no signs of disappearing.

Suddenly, all the spellcasters clearly saw that the bright light on the sixth layer of the Rune Tower actually began to flicker, and the light began to flicker, which proved that there had been changes in the sixth layer.

Either the light will disappear and Merlin will be sent out of the Rune Tower, but that would mean that Merlin, like Claes, will stop at the sixth layer.

Either the light directly ascends to the seventh layer, which will be even more sensational, which means that Merlin is the first caster to step into the seventh layer of the Rune Tower since the construction of the Rune Tower!

"Will it fail and be sent out of the Rune Tower?"

"Claes also stopped at the sixth layer at the beginning, which shows how difficult the sixth layer is. Will Mage Merlin be able to break through?"

Everyone knew how difficult the sixth floor of the Rune Tower was. For whether Merlin will be able to work miracles. No one is sure!

"Huh".

Suddenly, the bright light dimmed slightly, and then, an even more dazzling light suddenly rose from the seventh layer, and at the same time, a huge ball like crystal glass at the top of the Rune Tower also emitted a dazzling brilliance, covering almost the entire Dark Spirit Domain.

Such a huge momentum. It was the first time that everyone had seen it, and it would only appear if the caster had stepped into the seventh and last floor of the Rune Tower.

"On the seventh layer, Mage Merlin has actually really stepped into the seventh layer! The first person in the Dark Spirit Domain for thousands of years is none other than Mage Merlin!"

"What Claes didn't do, Mage Merlin did, God bless me in the Dark Spirit Domain, a genius like Claes betrayed the Dark Spirit Domain. But there is a spellcaster who shines brighter than Claes's light and is more genius than Claes!"

"The invisible confrontation between Mage Merlin and Claes. At this moment, the winner has been decided, and Mage Merlin is even better!"

Many of the spellcasters looked excited and excited, and some couldn't help but cheer, not least because Merlin was the first caster to step onto the seventh floor after the construction of the Rune Tower for thousands of years.

More reason, or because of the significance of Merlin's stepping into the seventh layer, one of the most important meanings is that in the invisible confrontation with Claes, Merlin won!

Mage Leo finally smiled, and although his smile was so terrifying that the casters around him were even less close and far away, he still laughed, and it was a smile from the heart......

"I didn't expect that I, Leo, would be able to have such a wonderful student one day!"

Mage Leo touched the terrifying blood-colored vertical eyes on his forehead with his hand, as if thoughtful......

"Whoosh".

On the seventh floor of the Rune Tower, a white light suddenly appeared, and then, Merlin's figure gradually appeared in the seventh layer.

"Hoo ......"

Merlin let out a long sigh of relief, he finally reached the seventh level of the Rune Tower, and in the invisible confrontation with Claes, he seemed to have the upper hand.

However, Merlin knew that this was just a victory over Claes many years ago, and now Claes, who has taken refuge in Osmu, I don't know how terrifying it has become.

"I'm really looking forward to beating you head-on!"

Merlin sighed, then began to look at the last floor of the Rune Tower.

As the last layer of the Rune Tower, there is nothing to observe about the furnishings inside, the most important thing is the Guardian Spirit, the Guardian Spirit of the last layer of the Rune Tower.

According to the rules of the Rune Tower, the strength of the guardian spirit of each layer will have a qualitative improvement, and the guardian spirit of the last layer of the rune tower must be even more powerful, even reaching the point of a seventh-level spellcaster, for Merlin, he is still far from reaching the strength to be able to compete with a seventh-level caster!

"Welcome, lucky spellcaster, you are the first spellcaster to step into the seventh layer in a thousand years!"

At this moment, a familiar voice sounded, Merlin was slightly stunned, and then stared at mid-air, a familiar figure appeared.

It was a black cat with extremely elegant movements, a pitch black body, and a haughty demeanor, and it was also a lazy appearance, as if it had not woken up.

But Merlin was all too familiar with the black cat.

"Why are you here?"

Merlin was a little stunned, isn't this magical black cat outside the Dark Spirit Domain, the divine black cat Didymoth in the stone tablet? Why is it that he is actually in the Rune Tower now, and has become the guardian spirit of the last layer of the Rune Tower?

"Uh...... It's you, rookie mage!"

The aura of the black cat was originally walking in the air, and its arrogant attitude didn't even bother to look at who had broken through to the seventh layer, but after hearing Merlin's stunned voice, it hurriedly took a look and found that it was actually an "acquaintance" Merlin, and the aura of his body disappeared in an instant, and he became lazy again.

Merlin took a deep breath and bowed slightly, "Dear Lord Didmoth, my name is Wilson Merlin!"

The black cat Didymoth shrugged his head, shook his two black claws slightly, and said as if he was weak, "Okay, Master Merlin, since you have found out, then I might as well tell you." This was all arranged by Archmage Fidel. Throughout the Dark Realm. As long as there are runes. Basically I can control it, so I can travel freely to any part of the Dark Realm. As for the seventh layer of the Rune Tower, I will occasionally make a cameo appearance as a guardian spirit, anyway, for so many years, no one has ever broken through to the seventh layer except you......"

The guardian spirit of the seventh layer of the mysterious rune tower was actually only an occasional "cameo" by the black cat Didemos, which made Merlin a little ridiculous. Very helpless feeling.

"Lord Didemos, what is the test of the seventh layer of the Rune Tower?"

Merlin hesitated for a moment, but asked softly.

The black cat Didymoth took a deep look at Merlin, raised a black claw, and said, "Mage Merlin, although you know me and often give me such delicious and crispy elemental crystals, you don't expect me to 'release water' to let you break through the seventh floor of the Rune Tower. In order to find a suitable spellcaster, Archmage Fidel spent a lot of effort to build the Rune Tower. Even if I am a guardian spirit, I can't break the rules set by Archmage Fidel!"

For this. Merlin naturally had been mentally prepared for a long time, although the black cat Didymos was a little magical, but even if it was magical, it was just the spirit of the rune circle, it would always be bound in the rune circle, and naturally it needed to follow the rules set by Archmage Fidel.

"Lord Didemos, don't worry, if you want to break through the seventh layer, it will naturally rely on my true strength!"

The black cat Didymoth nodded and said: "Very good, in fact, there is only one real test, that is, your understanding and comprehension of runes, using runes, quickly make a rune tool, only if you meet the requirements of Archmage Fidel, can you pass through the seventh layer and obtain the most important treasure left by Archmage Fidel!"

"There is only one kind of test?"

Merlin frowned, sure enough, this rune tower was really established by Archmage Fidel in order to cultivate spellcasters who are good at runes, but after so many years, no one has been able to step into the seventh layer, let alone meet the requirements of Grand Master Fidel.

Moreover, Merlin was not proficient in runes at all, but only briefly understood some common sense of runes, and it was difficult to even arrange rune arrays, let alone make rune tools.

"Lord Didemoth, is there really only one test, and is there any other way to pass it?"

Merlin said to Didymoth with a bitter face.

"Is there any other way? Actually, there are some of them, but at the beginning, Archmage Fidel was just a random setting, such a person, even in the most glorious era of spellcasters, was the top demon genius, if such a caster really appeared, even if he didn't know runes, he was willing to give away the treasure. ”

The black cat Didymoth pondered for a long time before he finally remembered the second test of Archmage Fidel, or it was no longer a test, which even Archmage Fidel thought was impossible.

"What solution? Lord Didemos, I don't know much about runes, and I don't need to think about this first test, so I want to try this second test. ”

Merlin directly said that he didn't know runes at all, and the black cat Didemos was also surprised, but it was only a few years before he saw Merlin enter the dark spirit realm and become the current six-series third-level spellcaster, just building spells requires a lot of energy, and if he is still proficient in runes, it is not normal.

So, the black cat Didymoth continued: "This second test is very simple, that is, defeat me! Mage Merlin, although I am the spirit of the rune array, but with the blessing of the rune array arranged by Mage Fidel, I can burst out with the strength of a seventh-level spellcaster, hehe, if you choose the second method, then you will face almost the same as a seventh-level spellcaster!"

"Level 7 Spellcaster!"

Merlin wasn't surprised, he had actually vaguely guessed that this would be the case.

The Rune Tower only allows casters below level four to enter, and casters below level four want to defeat level seven casters, this is simply a fantasy, perhaps in the most glorious era of spellcasters, there are also such demonic geniuses, but that is also pitiful, almost one hand can be counted.

At present, Merlin has seen the most evil is the legend of Nikolai that he heard the spirit of the law of fire mention on Nikolai's ship, and defeated the seventh-level caster when he was a fourth-level spellcaster.

Even the Legend of Nicholas, who has achieved a great legend, defeated the seventh-level caster only after becoming a fourth-level spellcaster, and below the fourth level, the Legend of Nikolai is never the opponent of a seventh-level caster.

Therefore, the second test method set by Archmage Fidel, even he himself did not believe that such a person would appear.

However, if such a demonic genius really appears, even if he is not proficient in runes, Archmage Fidel is willing to give away the treasure, the fundamental reason is because such a spellcaster, too few and too few, once he grows up, it will be very terrifying, and he is destined to become one of the greatest spellcasters!

"How's it going?

The black cat Didymoth urged again, and looking at its appearance, he was also a little impatient.

Merlin took a deep breath, then nodded heavily, and said in a firm tone, "Think about it, Lord Didymoth, let's do it!"

"Oh, looks like you've chosen the second option......"

Didymoth, the black cat, looked up and stared at Merlin with a smirk. (To be continued......)
