The Black Giant Wolf is the guardian spirit of the fourth level rune tower, which can be compared with the fourth level spell caster. Although the three spell casters just now can defeat the Black Giant Wolf alone, it also seems a bit difficult and took a long time to defeat it.

Merlin was watching the other side for a while and learned about the characteristics of the black giant wolf. It is fast and has a strong defense. Even if it is attacked by a level 4 spell, it can withstand it. It is quite difficult for ordinary level 3 or even level 4 spell casters.

"Fast speed? Strong defense?"

A smile appeared between the corner of Meilin's mouth. The characteristics of the black giant wolf were almost restrained by him. In terms of speed, Meilin had a momentary wind and extremely fast. In terms of defense, Meilin had even more earth-fusion magic power integrated with magic, which could withstand the attack of level 6 spells.

"Swoosh".

The black giant wolf turned into a black light and rushed towards Meilin. Meilin gently stretched out his fingers, and a trace of white fire appeared in his white fingers.

"laugh".

Meilin bounced his fingers, and a white light flew out and spread quickly, turning into a fireball the size of a fist.

"Bang".

The fireball hit the black giant wolf hard. The black giant wolf didn't even react and was directly wrapped in flames and instantly dissipated in the scorching high temperature.

“Too weak!”

Merlin shook his head slightly. Perhaps for ordinary spell casters, the fourth level of the rune tower is the real test, because only when it reaches the fourth level can the guardian spirit be comparable to the fourth level caster, and the strongest one can enter the rune tower is the third level caster.

Starting from the fourth level, the caster basically needs to challenge the challenge above the level. Therefore, it is called the real test!

However, Merlin is not an ordinary spell caster, and the fourth level is not a test for him.

"Next. It's the fifth floor!"

Meilin was covered with white light and disappeared in an instant.

****

On the fifth floor, Master Sarah, Mage Enwea, and Mage Ilman, these three spellcasters were staring at the stone pillars in front of them with serious expressions.

Master Enweiya turned around and looked down, and said in a deep voice: "We have to seize the time. I didn't expect that Merlin was so fast. He was almost catching up with us. He had to defeat the guardian spirit of the fifth level at the fastest speed and break through the fifth level!"

The fifth floor of the Rune Tower is something that no one of them can pass through, even if they unite together, they feel very difficult.

The only hope is that the Mage Enweiya spent a huge price to obtain the Koleman rune magic plate. The three of them were all in the Dark Spirit Realm. They have studied runes more profoundly and are considered very rune-capable spellcasters.

It is precisely because of this that the three of them can activate a magic array as complex as the Koleiman rune magic array. This is their only hope, and it is their reliance on breaking into the rune tower this time.

Rune magic circles were not inferior to Pandora's magic energy in the most glorious era of spellcasters. It was just that because studying runes requires too much energy and takes too long, many spellcasters simply chose to practice Pandora's magic energy, and were unwilling to study runes.

And now, when the casters are completely declining, runes have completely declined. There are very few spellcasters who can master runes, that is, the Dark Spirit Realm is good at runes. Therefore, some spellcasters who are excellent in runes appear.

These three people are undoubtedly in the Dark Spirit Realm and have excellent talents in runeology. Otherwise, if someone else is replaced, even if they get the Koleman rune plate, they will not be able to activate it.

Seeing the nervous look of Master Enweiya, Master Ilman seemed very calm and said relaxedly: "Mage Master Enweiya, don't worry, the black giant wolf on the fourth level is not that easy to deal with. Even if Merlin is really a genius like Chrys, it will take some effort to deal with the black giant wolf. We have plenty of time to pass through the fifth level!"

Master Enweiya also nodded slightly. He also knew that the black giant wolf on the fourth level was not so easy to deal with. It took them a long time before they passed.

However, he said cautiously: "You have to seize the time and don't take it lightly! Let's start, we will first integrate our mental power into the Koleman rune magic plate and make all preparations. When the guardian spirit on the fifth level appears, we will activate the magic plate, combine the power of the three of us to activate the Koleman rune magic array, and kill the guardian spirit on the fifth level in one fell swoop!"

As the words fell, a disc emitting white light had appeared in the hand of Master Enweiya, and on the disc, there were dense mystical runes engraved.

This is the Koleman rune magic plate, which is very precious. It was obtained by Master Enweiya at a huge cost. At least three spellcasters who are proficient in runeology can be activated smoothly.

However, once the magic plate is activated, it can trigger the Koleman rune array that has been arranged in the magic plate, and burst out with unparalleled power.

When seeing the rune palette of Koleman, a hint of envy appeared in the eyes of Master Sarah and Mage Ilman. Rune palettes like this are very precious. As a spell caster organization that is good at rune, there are naturally such rune palettes in the Tower of All Things, and there are even rune palettes that are stronger than Coleman.

However, the price of those rune palettes is unimaginable. Any rune palette often requires thousands of contribution points, which is too expensive for spell casters at level 4 or above.

Even the Koleman rune plate obtained by Master Envia was not exchanged from the Tower of Everything, but obtained from outside through some special methods.

That is, Master Enweiya, who comes from a powerful family of spellcasters, can have such huge wealth to buy a rune magic plate. As for Master Sarah and Ilman, they can only secretly envy it.

"Hurry up and put your mental power into the rune magic plate..."

Master Enweiya said in a deep voice.

Master Salah and Master Ilman were also a little impatient. Although they had simulated it before, the simulation was a simulation. Master Enweiya would not take out such a precious rune magic plate for them to try. Only when they really need to use it will they allow them to engrave their mental power into the rune magic plate.

"Swoosh".

Suddenly, a white light flashed through the fifth floor. Master Enweiya and others immediately noticed the change and stared at the sudden appearance of the white light.

Soon, a black robe figure gradually walked out of the white light.

Seeing this figure, Master Enweiya and others changed their faces instantly.

"How could it be so fast? How could the guardian spirit on the fourth level be defeated so quickly?"

"I actually broke to the fifth floor. I thought Meilin would delay the fourth floor for a while, but I didn't expect that in the blink of an eye, Meilin arrived at the fifth floor. It seemed that the black giant wolf on the fourth floor did not cause any trouble to Meilin at all."

Master Ilman, who just swore to the point where Merlin would spend some time on the fourth floor, had a very awkward expression, but no one was paying attention to him at this time. Master Enweiya only had a strong sense of urgency.

"Quick, engrave the mental power into the rune plate. Merlin is stronger than we imagined. We must not let him break into the sixth level first!"

Master Enweiya immediately urged, so Master Sarah and Master Ilman also came to their senses and immediately mobilized their mental power to carve a trace of mental power into the rune magic plate.

"Buzzing"

Suddenly, the rune plate in the hand of Master Enweiya immediately burst out with a dazzling light, and mysterious runes appeared in the air one after another, and then flew to the surface of the three people, like a layer of armor, protecting all three people in the mysterious runes.

After doing all this, Master Enweiya and the other three of them did not delay and stepped directly into the middle of several vermilion stone pillars and began to face the guardian spirit on the fifth level.

Meilin, who had just arrived at the fifth floor, frowned slightly, feeling a little inexplicably. He felt a hint of hostility from the eyes of Master Enweiya and the other three.

Merlin remembered very clearly that he didn't know these three people at all, so how could anyone become hostile to him? It was really a bit inexplicable!

However, when he saw Master Enweiya and others rushing into the vermilion stone pillar and starting to challenge the guardian spirit on the fifth level, Meilin had a glimmer of enlightenment in his heart.

It turned out that these three people were afraid that he would pass through the fifth floor first, or even the sixth floor first. After all, no one could pass through the sixth floor for thousands of years of inheritance in the Dark Spirit Realm. Therefore, there are also treasures left by the great master Fidel himself in the sixth floor.

Thinking of this, Meilin shook his head helplessly. This kind of "hostility" was really a bit inexplicable. In his opinion, the three people including Master Enweiya were not strong in their own strength. The fifth level was already their limit. It was difficult to get through the fifth level, let alone the sixth level.

Therefore, Meilin was not in a hurry, but squinted his eyes slightly, stood aside, and watched carefully the three of them fighting against the fifth-level guardian spirit.

Although Merlin is very strong, after reaching the fifth level of the Rune Tower, he had to be more cautious. The guardian spirit arranged by Master Fidel is stronger than the other, and he cannot be despised at all.

"Wow!"

Just like the sound of water flow, when Master Enweiya and the other three stood in the middle of the vermilion stone pillar, all the stone pillars emitted a rich white light. These white lights gathered together, like small streams, and finally gathered into a vast ocean!

A "fier" aura appeared faintly in the rich white light, which had never appeared on the first to fourth floors of the Rune Tower.

"roar……".
Chapter completed!
