"Book library?"

Meilin looked up and looked carefully at the two huge doors in front. There were two stone piers on both sides of the door. On the stone piers were carved with some monsters that Meilin had never seen before. Although they were lifelike, they seemed to make people feel cold from the bottom of their hearts.

There seemed to be a strange feeling around the library of the Abyss Castle.

Merlin frowned and then looked at Master Leo.

Master Leo's face was calm and he said lightly: "Go in and choose the spell you need!"

Merlin nodded, then took a deep breath and walked towards the two doors.

However, as soon as he stepped on the stairs, he immediately felt darkness in front of him, and it seemed that the surroundings were immediately dark. He had no perception, no perception, no perception.

"Illusion?"

Meilin was shocked. He experienced countless illusions in the dark mystery, and when he was practicing the dark heart, he also experienced countless illusions. Therefore, he was very familiar with illusions. Now that such a sudden change occurs, he immediately knew it was an illusion.

But soon, without Merlin's release of strong belief, the runes of the dark heart on his chest immediately emitted a warm breath. Then, Merlin's leader suddenly shuddered and felt a cool feeling, and then he woke up.

This is the role of the Heart of Darkness. It was obvious that he was attacked by the dark spell just now. The Heart of Darkness played its role and could resist most of the dark spells. With the Heart of Darkness, especially the third kind of Darkness, Merlin is difficult to be harmed by the dark spell.

"who?"

Master Leo first reacted. A bloody vertical eye on his forehead immediately flashed through a trace of bloody light, then cut through the void and shot towards a dark place.

"Bang".

There was a muffled sound. Immediately afterwards, a thin old man in black robe appeared from the attack of Master Leo's Dark Eye, and he staggered forward a few steps, as if he had just resisted the attack of the Dark Eye, and it seemed very reluctant to resist the attack of the Dark Eye.

"Eye of Darkness?"

The skinny old man's face changed and seemed a little surprised. Then he looked at Meilin again and said in a low voice: "Heart of Darkness!"

The thin old man's eyes scanned back and forth between Merlin and Mage Leo, and his expression seemed a little gloomy. He was a dignified seventh-level spell caster. As a result, he released his spell, but failed to pull Merlin into a illusion. Moreover, no level six-level spell caster cast the Dark Eye, making him feel embarrassed.

"Master Leo, don't get me wrong, this is Master Tesman who is guarding the library!"

When Master Hobis saw the thin old man, he hurriedly stepped forward and explained.

Master Leo did not continue to use the Dark Eye, but just used the blood-colored vertical eyes on his forehead, looking at the thin old man coldly, without relaxing his guard.

Meilin also looked at the thin old man in confusion. The other party had obviously released a spell just now, but he didn't notice the slightest movement, which showed that the thin old man was at least a level seven spell caster.

However, the dark spell released by the seventh-level spell caster was easily blocked by Merlin's Dark Heart, which also reflects another function of the Dark Heart, which is to resist most dark spells.

In other words, even the dark spells released by the seventh-level caster are difficult to hurt Merlin.

After a while, Master Hobis seemed to have explained it clearly to the thin old man Master Tesman, so he walked over and said to Merlin: "Mage Merlin, you can go in and select spells now. After choosing the spells, Master Tesman will untie some rune arrays on the spells for you."

Merlin nodded. Like the Dark Spirit Realm, in the library of the Abyss Castle, these spells are protected by specific rune arrays. Master Tesman himself needs to remove the rune array on the spell to see the content of the spell.

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

The thin old man, Master Tesman, looked at Master Leo deeply, then said in a low voice: "Eye of Darkness, not bad, what you have cultivated is the real Eye of Darkness!"

After saying that, the thin old man also followed Mei Lin and entered the library.

Master Leo was unmoved by the thin old man's words. The only eye on his forehead looked at Merlin's disappearing back, and it seemed that he gradually overlapped with a figure in his mind.

"Redoer...my brother looks like it! Are you back?"

Master Leo lowered his head and murmured softly, with a look of nostalgia on his face.

****

As soon as he walked into the library, Mei Lin felt a trace of coldness. The entire library was different from the Tower of All Things in the Dark Spirit Realm. The Tower of All Things in the Dark Spirit Realm was crowded with people coming and going, but the library was deserted and seemed to have been no one for a long time.

Merlin was a little confused. Could it be that there were no casters in the Abyss Castle to choose spells?

"The Abyss Castle is different from your Dark Spirit Realm. There are very few spellcasters in the Abyss Castle. Not every spellcaster can adapt to dark spells... Okay, hurry up and choose. Your mentor Leo is willing to use the Dark Eye to let you choose spells. You must cherish it."

A sharp and harsh sound suddenly sounded behind Merlin. It was the Tesmann Mage who used spells to attack Merlin without any expression before.

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

These spells are not all dark-type spells. After all, the Abyss Castle is just good at dark-type spells. If you want to become a powerful spellcaster, you still need other spells.

However, in this library, the number of dark spells is the largest, accounting for as much as 30% of all spells.

Merlin easily found a bookshelves for dark spells. On the bookshelf, there are everything from level 2 to level 6 spells, and there are a lot of types, which makes Merlin a little difficult to choose for a while.

"You can build six-series spells, and I think you have some experience in building a spell model. Leo paid such a great price to choose spells in the Abyss Castle, and it is definitely not for you to choose ordinary spells. Hehe. If you have confidence, go to the last row of bookshelf to choose from. There are some of the most peculiar, unique, powerful, and most complex spells."

Master Tesman stared at Merlin all the time. Seeing that Merlin seemed to have no idea how to start, he pointed to the last row of bookshelfs to remind Merlin.

Merlin looked slightly happy. He had a matrix number. He was not afraid of how complicated the spell model was. On the contrary, he needed to choose the spell that suited him the most and was relatively powerful. After hearing the advice of Master Tesman, Merlin didn't have to waste time elsewhere, so he walked straight to the last row of bookshelf in the library.

There were only a small number of spells placed on the bookshelf. Meilin pulled out a spell book and gently opened it. Seeing the introduction of spells above, Meilin immediately became interested.

The spells here are indeed not simple spells. They either have unique effects or are extremely powerful in spells, but the spell model is also very complex.

The dark mist and the spells of the Dark Realm that Merlin had previously constructed are all on this last row of bookshelf.

However, the spell Merlin wants to choose this time is from level 2 to level 6 spells. Each spell will choose one spell. As for level 7 spells above level 6, it is not available to any spellcaster organization. Once it reaches the peak of level 6 spells, if you want to become a level 7 spellcaster, you must deduce the most suitable spellcaster for the caster himself. Other spells will not play any role.

Meilin carefully selected various spells on the bookshelf. After all, once the spells were selected, they would be built into the sea of ​​consciousness in the future, so Meilin had to carefully choose them.

Master Tesman was not in a hurry, squinted his eyes slightly, and quietly watched Merlin slowly looking at one spell after another.

About four or five hours later, a smile finally appeared on Merlin's face. Two books had appeared in his hand, which meant that he had selected two spells.

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

Both spells have strong hallucination effects. Once the dark tide is successfully constructed and released, it will be more terrifying than the dark light realm. When the darkness comes, it will be as powerful as a rolling tide.

The third-level spell Dark Vortex is said to be able to devour all spirits. Even a spellcaster with a strong spirit will be swallowed up once it falls into the dark vortex, and then falls into the illusion.

These are second-level spells and third-level spells, both of which are spells with extremely powerful spells and particularly complex spell models. Even many spell casters in the Abyss Castle dare not easily choose these two spells.

However, Merlin can quickly choose level 2 and level 3 spells, but he seems very cautious in the fourth spell.

Once the level 4 spell is selected, it can be merged with the Dark Heart and its power will be increased several times. Therefore, Merlin will be very cautious about spells above level 4.

"The dark nightmare, known as the ultimate illusion, can make people and gods fall into an extremely real illusion without knowing it. Moreover, layer after layer of illusion makes people unable to distinguish between reality and illusion, just like a nightmare, it makes people feel terrifying..."

Finally, Merlin's eyes fixed on a "Dark Nightmare" spell, which happened to be a level 4 spell, which belongs to the ultimate illusion.

Such illusions can confuse most of the casters. Of course, if you can't even confuse the dark nightmare, there will actually be no spells that can confuse them.

Moreover, once the mental power reaches a certain level, it is difficult to be confused. Even the strongest illusion is the same. It is difficult to confuse those casters with extremely strong mental power.

Therefore, the dark spells and hallucinations of the psychedelic species have almost reached the extreme when they reach the level 4 spell "Dark Nightmare". The level 5 spells that go up are often illusions and real attacks, and illusions are often only auxiliary.

After pondering for a long time, Meilin chose this level 4 spell Dark Nightmare, which is known as the ultimate illusion, without hesitation. At this time, it had been three days since Meilin entered the library.

Next, Merlin has to continue to choose level 5 spells and level 6 spells. This is a brand new field. The limit of illusion is the Dark Nightmare Spell. After that, the dark spells will develop towards physical attacks.

After all, dark spells are not just hallucinations!
