"Library?"

Merlin raised his head and looked carefully at the two huge gates in front of him, on both sides of the gate, there were two stone piers, and on the stone piers were carved some monsters that Merlin had never seen before, although they were lifelike, but they seemed to make people feel a chill from the bottom of their hearts.

Around the library of the Abyss Fortress, there seems to be a strange feeling.

Merlin frowned, then looked at Mage Leo.

Mage Leo had a calm face and said lightly, "Go in and choose the spell you need!"

Merlin nodded, then took a deep breath and walked to the two gates.

However, as soon as he stepped on the stairs, he felt a darkness in front of him, and his surroundings seemed to be immediately dark, and he had no sense, no seeing, no hearing, no perception.

"Illusion?"

Merlin was shocked in his heart, he had experienced countless illusions in the dark maze, and when he cultivated the heart of darkness, he had also experienced countless illusions, so he was very familiar with the illusion, and now that such an accident suddenly appeared, he immediately knew that the path was an illusion.

But soon, before Merlin could release a powerful conviction, the runes of the Heart of Darkness on his chest immediately exuded a warm aura, and then, Merlin's leader suddenly felt a coolness, and then he came to his senses.

This is the role of the Heart of Darkness, just now it was obvious that he was attacked by dark spells, it was the Heart of Darkness that played a role, it can resist most of the dark spells, there is a Heart of Darkness, especially the third type of Heart of Darkness, Merlin is difficult to be hurt by dark spells.

"Who?"

Mage Leo was the first to react, his blood-colored eyes on his forehead. Immediately, a blood-colored light flashed. Then it cuts through the void. Shoot towards a dark place.

"Bang".

There was a muffled sound, and then, a thin black-robed old man actually appeared from the attack of Master Leo's Dark Eye, and he also staggered a few steps forward, it seemed that he was very reluctant to resist the attack of the Dark Eye just now.

"Eyes of Darkness?"

The thin old man's face changed. Seemingly surprised, he looked at Merlin again, and said in a low voice, "Heart of Darkness!"

The thin old man's gaze scanned back and forth between Merlin and Mage Leo, his expression was a little gloomy, he was a dignified seventh-level spellcaster, and as a result, he released a spell, but he failed to put Merlin into an illusion, and there was no sixth-level spellcaster who cast the Eye of Darkness, which made him embarrassed.

"Master Leo, don't get me wrong. This is the Tesman mage guarding the library!"

When Master Hobbis saw the thin old man, he hurriedly stepped forward to explain.

Mage Leo didn't continue to cast the Eye of Darkness. just used the blood-colored eyes on his forehead to look at the thin old man coldly, and did not relax his vigilance.

Merlin also looked at the thin old man suspiciously, the other party obviously released a spell just now, but he didn't notice the slightest movement, which shows that this thin old man is smart, at least a seventh-level spellcaster.

However, the dark spells released by the seventh-level caster were easily resisted by Merlin's Dark Heart, which also reflected another role of the Dark Heart, that is, it could resist most of the dark spells.

In other words, even the dark spells released by the seventh-level caster would hardly hurt Merlin.

After a while, Mage Hobbis seemed to have explained clearly to the thin old man, Mage Tessman, so he walked over and said to Merlin: "Mage Merlin, you can go in and choose a spell now, after choosing a spell, Mage Tessman will unlock some rune circles on the spell for you." ”

Merlin nodded, like the Dark Spirit Domain, in the library of the Abyss Fortress, these spells are also protected by a specific rune circle, and it is necessary for Master Tesman to personally remove the rune circle on the spell in order to see the content of the spell.

So, Merlin continued to walk forward, and the two huge stone doors slowly opened, and then Merlin's figure disappeared from everyone's sight.

The thin old man, Mage Tesman, glanced at Master Leo deeply, and then said in a deep voice: "Dark Eye, yes, what you have cultivated is the real Dark Eye!"

After that, the thin old man also followed Merlin into the library.

Mage Leo was unfazed by the thin old man's words, and the only eye on his forehead, looking at Merlin's vanishing back, seemed to overlap with a figure in his mind.

"Redor...... My brother, it's like you're back?"

Mage Leo lowered his head and muttered softly, a look of nostalgia on his face.

As soon as he walked into the library, Merlin felt a trace of coldness, the entire library was different from the Tower of Vientiane in the Dark Spirit Domain, the Tower of Vientiane in the Dark Spirit Domain, people came and went, it seemed very lively, but this library was deserted, and it seemed that no one had been here for a long time.

Merlin was a little puzzled, could it be that there were no spellcasters in the Abyss Fortress to choose spells?

"The Abyss Citadel is different from your Dark Spirit Domain, the Abyss Citadel has very few spellcasters, and not every caster can adapt to dark spells...... Okay, hurry up and choose, your mentor Leo, is willing to use the Eye of Darkness to let you choose spells, you have to cherish it. ”

Behind Merlin, a somewhat sharp and piercing voice suddenly sounded, it was the Tesman mage who had been silent before, attacking Merlin with a spell.

Merlin nodded thoughtfully, and then began to look at the large number of spells in the library.

These spells are not all dark spells, after all, the Abyss Fortress is only good at dark spells, and if you want to become a powerful spellcaster, you still need spells from other systems.

It's just that in this library, the number of dark spells is the largest, accounting for as much as thirty percent of all spells.

Merlin easily found a bookshelf for dark spells, and on the bookshelf, there were everything from second-level spells to sixth-level spells, and there were so many types that Merlin was a little difficult to choose for a while.

"You can build six series of spells, and I think you still have some experience in the construction of spell models. Leo paid that big price. Lets you go to the Abyss Fortress to pick spells. It's certainly not for you to pick and choose a generic spell. Hehe, if you're confident, go to the back row of bookshelves and pick some of the most peculiar, unique, powerful, and complex spells. ”

Mage Tesman kept an eye on Merlin, and saw that Merlin seemed to have no idea what to do. He pointed to the back row of bookshelves and reminded Merlin.

Merlin's expression was slightly happy, he had a matrix number, and he was not afraid of how complicated the spell model was, on the contrary, he needed to choose the spell that was most suitable for him, and it was also relatively powerful, and after hearing the advice of Master Tesman, Merlin didn't need to waste time elsewhere, so he walked straight to the back row of bookshelves in the library.

There were only a handful of spells on the shelves. Merlin casually pulled out a spell book and opened it gently. Seeing the above introduction to spells, Merlin immediately became interested.

The spells here are not simple spells, they either have unique effects, or the spells are extremely powerful, but the spell models are also very complex.

The spells of the Dark Mist and the Darklight Domain that Merlin had previously constructed were all on the back row of bookshelves.

However, the spells that Merlin wants to choose this time are from second-level spells to sixth-level spells, and each level of spells will choose a spell, as for the seventh-level spells above the sixth level, that is not available in any caster organization, once it reaches the peak of the sixth-level caster, if you want to become a seventh-level caster, you must deduce the most suitable spell for the caster's own spell, and other people's spells will not play any role.

Merlin carefully selected the various spells on the bookshelf, after all, once he chose a spell, he would build into the sea of knowledge in the future, so Merlin had to choose carefully.

And Mage Tesman was not in a hurry, squinting his eyes slightly, quietly watching Merlin slowly flip through one spell after another.

After about four or five hours, a smile finally appeared on Merlin's face, and two books had appeared in his hand at this time, which meant that he had already selected two spells.

These two spells are the second-level dark spell Dark Tide and the third-level spell Dark Vortex.

Both of these spells have a strong hallucinogenic effect, once the tide of darkness is successfully constructed and released, it is even more terrifying than the domain of dark light, and the darkness descends like a rolling tide, which is very powerful.

And the third-level spell dark vortex, which is claimed to be able to devour all spirits, even if it is a caster with a very strong spirit, once it falls into the dark vortex, its spiritual power will be devoured, and thus fall into the illusion.

These are second-level spells and third-level spells, both of which are spells with particularly powerful spells and particularly complex spell models, and even many spellcasters in the Abyss Fortress do not dare to choose these two spells easily.

However, Merlin can quickly choose second- and third-level spells, but fourth-level spells, he seems to be very cautious.

Once the fourth-level spell is selected, it can be fused with the heart of darkness, and the power is increased several times, so Merlin will be very cautious about spells above level four.

"Dark nightmares, known as the ultimate of illusion, can make people fall into extremely real illusions without knowing it, and layer after layer of illusions, making people unable to distinguish between reality and illusion, just like nightmares, people feel terrifying......"

Finally, Merlin's gaze was fixed on a "Dark Nightmare" spell, which also happened to be a fourth-level spell, which belonged to the extreme of illusion.

This kind of illusion can confuse most spellcasters, of course, if you can't even confuse the dark nightmare, then there is actually no spell that can confuse.

Moreover, once the spiritual power reaches a certain level, it is difficult to be confused, even if the illusion is strong, it is the same, it is difficult to confuse those spellcasters with extremely strong mental power.

Therefore, the hallucinogenic type of dark spells has almost reached an extreme when it reaches the fourth-level spell "Dark Nightmare", and the fifth-level spells above are often illusions and real attacks in parallel, and illusions are often only auxiliary.

After pondering for a long time, Merlin did not hesitate to choose this fourth-level spell Dark Nightmare, which is known as the ultimate illusion, and at this time, it had been three full days since Merlin entered the library.

Next, Merlin has to continue to choose between level 5 spells and level 6 spells, which is a new realm, and the limit of illusion is the dark nightmare spell, after which the dark spells will develop towards physical attacks.

After all, dark spells aren't just hallucinating!
