The arrival of Merlin and Mage Leo caused some sensation. Mage Leo smiled at Merlin and said, "Merlin, look at the spell casters around you, you are looking forward to you breaking into the Rune Tower."

Merlin was naturally very clear about the discussions of the spellcasters around him, but he also knew that these people were not expecting him to break into the rune tower, but looking forward to seeing his invisible "confrontation" with Chrys.

Merlin looked up at the towering rune tower, and his heart was filled with a hint of fighting. He didn't mind the others comparing him with Chrys. Even himself wanted to have a real battle with Chrys.

However, Chrys betrayed the Dark Spirit Realm and defected to Osm, he never showed up again, and Merlin did not have the chance to compete with Chrys. However, with the Rune Tower, he can be indirectly compared with Chrys.

"Mentor Leo, I'll go in first!"

Merlin whispered to Master Leo, then turned around, and the waves of wind element appeared on his body, and in the blink of an eye he flew into the mysterious rune tower.

****

In the rune tower, Merlin just entered it and saw three spellcasters, two men and one woman, who seemed to be level three spellcasters.

"Swoosh".

Before Merlin could look at the three spellcasters carefully, she saw them being shrouded in a white light and disappeared into the first floor of the rune tower in the blink of an eye.

“Passing the first floor?”

Mei Lin was slightly stunned, and then he thought that these three people might have passed the first floor of the Rune Tower and entered the second floor.

In the rune tower, spell casters are surfing almost every day. Even if they fail, they will not die. They will only be sent directly into the rune tower. A certain contribution point will be deducted.

After all, the purpose of Master Fidel's construction of the rune tower was not to kill the low-level spell casters in the Dark Spirit Realm, but to select the best spell casters, especially those who are good at runes, as the key target of cultivation, and to give some unique and powerful treasures. Therefore, even if you fail, you will not die.

Merlin did not bother to guess the three spellcasters, but came directly to the middle of the first floor, where there were a few vermilion red pillars, with dense mysterious runes engraved on them.

The aura of these runes is faintly similar to the runes on the stone tablet outside the Dark Spirit Realm. They should have been carved by Master Fidel himself. Even after thousands of years, they still have incredible power.

This is the magical power of runes. Merlin has seen many rune magic circles so far, and he even has a powerful rune magic plate.

However, when it comes to studying runes, I'm afraid no one can compare to Master Fidel. The rune magic array he carved can actually produce a breath of life, just like the spirit of the rune magic array in the stone tablet and the black cat Didimos, even a great legendary wizard cannot do it.

This shows how profound the study of Master Fidel’s rune is!

"Buzzing"

Mei Lin stood in the middle of the vermilion stone pillars. The mysterious runes on the stone pillars began to flash with a trace of white light, and these white lights quickly gathered together in the air. Gradually, a huge black dog appeared in the air.

The big black dog shook his ears, his eyes were distracted, he looked listless, and his aura was not strong, and he could even be considered quite weak.

However, what surprised Merlin was that this big black dog actually had a hint of "life" smell, which was very similar to Didimos, the black cat inside the stone tablet outside the Dark Spirit Realm.

Merlin took a few steps back and distanced himself from the black dog. After all, this was a rune tower. It was a tall tower built by the great master Fidel. Even these runes were carved by the master Fidel. No one knew how strong this big black dog was, so he needed to be careful.

The big black dog slowly raised his head and looked at Meilin. He actually spoke in a cold tone: "I am the guardian spirit of the first level of the Rune Tower. If I defeat me, I can enter the second level. If I fail, I will be sent out of the Rune Tower! Have you heard it clearly?"

Merlin nodded and said, "I heard it clearly!"

"Swish".

As soon as Merlin finished speaking, the big black dog took action. It was extremely fast and looked very lazy, but now it became extremely sharp. Its body was covered with mysterious runes, which made its size look even bigger.

The attack method of the big black dog was very simple and rushed around, but the force made Merlin feel a little confused. It was not very powerful, but it was too weak.

"Frozen space!"

Merlin did not use magic power, but directly released the third-level spell, cold space!

This frozen space expands from the iced area and can almost form a "space". Of course, it is not a real space, just a small place completely covered by cold air, from the sky to the ground, all covered.

"Click".

The third-level spell freezing space has both restraints and certain attack power. After all, the extreme low temperature is also quite powerful. Once frozen, many low-level spells cannot resist it. With the cowardly body of the caster, facing the extreme low temperature, they cannot survive at all.

Of course, the big black dog in front of him was not a spell caster, but it seemed even more unbearable. It was frozen directly by Merlin's frozen space spell. Then the ice crystal cracked and its figure disappeared.

"Just win like this?"

Merlin was a little stunned. Although it was only the first level, it seemed to be too simple...

"Swoosh".

After a while, a large black dog condensed again on the mysterious rune on the stone pillar. However, this time, the large black dog did not take action, but said to Merlin directly: "You have passed the first level of the rune tower, but don't be complacent. The first level of the rune tower is only equivalent to a first-level caster, but you are a third-level caster. Defeating me is nothing. Your real test is above the fourth level!"

Only then did Merlin realize that the guardian spirit on the first level of the rune tower was only equivalent to the first level caster, while the second level was equivalent to the second level caster. As the number of layers of the rune tower increased, the strength of the guardian spirit became stronger.

At level 4 or above, Merlin will face a real test, because the guardian spirit on the fourth level is comparable to the fourth level caster, the fifth level is comparable to the fifth level caster, and the sixth level is the sixth level caster. And the last level, the seventh level guardian spirit on the seventh level has reached the level of a seventh level caster!

The purpose of Master Fidel's construction of the rune tower was to select real geniuses in the Dark Spirit Realm, especially those who are good at runes. Therefore, he even allowed up to three spellcasters to unite and use the rune magic plate to pass the level.

However, even so, it is too difficult for a spellcaster below level 4 to defeat a spellcaster of level 7. No wonder no one in the Dark Spirit Realm has been able to break through the seventh level, and even the sixth level has not been able to break through the seventh level for thousands of years.

The strongest one is like Chrys, who only made it through the fifth level, but did not defeat the guardian spirit on the sixth level.

"Okay, go to the second floor."

After the big black dog finished speaking, his figure instantly disintegrated. Then, a white light flew out from the vermilion stone pillar, covering Meilin.

"Swish".

When Merlin's figure appeared again, he had already reached the second floor of the Rune Tower!

There are still a few vermilion stone pillars in the second floor. Mei Lin is already familiar with the environment in the rune tower, so he immediately stands in the middle of the vermilion stone pillar. Soon, the mysterious rune condenses the guardian spirit of the second floor, a fat squirrel.

This fat squirrel has a terrifying tail. It swept across and was very fast and could not be defended.

However, this attack could not hurt Merlin at all.

Then Merlin randomly cast a third-level spell and defeated the second-level guardian spirit and continued to the third-level of the Rune Tower.

The third layer of guardian spirit is a very terrifying white spider. This white spider will spit out tough white spider silk, and there is also a strange smell on the spider silk. As long as you smell this smell, you will feel paralyzed.

It is also easy to deal with this spider. Merlin directly used the collapse fire and easily burned the spider to ashes, defeating the third layer of guardian spirit.

Next, Merlin successfully ascended to the fourth floor of the Rune Tower, but this time, Merlin met the three spell casters he had seen on the first floor before.

These three spellcasters are all fighting against the fourth level guardian spirit, a powerful black giant wolf.

This black giant wolf is extremely fast and has a tough body. Even ordinary level 4 spells can withstand multiple times. Only by attacking a certain place continuously can the giant wolf be damaged.

Merlin watched the battle between the three spellcasters. These three spellcasters were actually four-type spellcasters, and the spells they built were quite outstanding. Therefore, even if they faced this black giant wolf alone, they could defeat them.

Although these three spellcasters are not geniuses like Chrys, they can definitely be called elites, especially in small spellcasters organizations such as the Dark Spirit Realm, they are definitely the targets of focus for training.

But these three elite spell casters are now united. It is obvious that they are going to hit the fifth or even the sixth floor of the Rune Tower!

"Bang".

Finally, these three spellcasters released the spell together, one of which bound the black giant wolf, and the other two spellcasters seized the opportunity and released the attack spell frantically, and instantly defeated the black giant wolf.

"I finally passed the fourth floor...but this is just the beginning of our test. Let's go and enter the fifth floor!"

The three spellcasters were faintly led by Master Enweiya. They looked back at Merlin, with a hint of eagerness in their expressions. Under the white light, the figures of the three disappeared again.

Merlin frowned and looked over his head. He could see that if there were no special means, the fifth level was the limit of these three spellcasters. It would be impossible to pass the fifth level!

"It's my turn!"

Meilin looked at several vermilion stone pillars, but a relaxed smile appeared on his face. Perhaps for ordinary third-level spell casters, breaking through the fourth level and facing a guardian spirit that is comparable to a fourth-level spell caster is the beginning of the real test.

But for Merlin, the fourth or even the fifth floor is no different from the first or third floors he has penetrated!

"Swoosh".

Meilin quickly stood in the middle of the stone pillar, and gradually, the white light emitted by the mysterious rune quickly gathered in mid-air.

Gradually, a figure of a giant black wolf appeared in the air!
