In the huge pitch-black hole, Merlin followed behind Master Leo, and his mental power was always aware of everything around him.

The dark passage was long, and Merlin could feel that they were continuing to go deeper underground, and instead of having a castle or anything like that, the Abyssal Fortress was built underground, with a huge passage that extended in all directions.

Soon, a glimmer of light gradually appeared in the dark passage, and the uneven walls showed a pale golden light.

"Here, Master Leo, it's not the first time you've come to my Abyss Fortress, but this little guy is probably the first time you've come to the Abyss Fortress, and I'm very curious!"

The old-looking Hobbis mage had a smile on his face when he saw Merlin looking around.

Merlin was indeed very curious, this hall was buried deep underground, but there was no feeling of suffocation, and in the corners of the hall, there were four white glassware that seemed to be lampshades, and there was a huge crystal pearl in it, and from the pearl, a soft white light was emitted, reflecting the underground hall as if it were day.

All the facilities of the Abyss Fortress made Merlin feel a little incredible.

"Alright, let's get down to business! Mage Leo, what do you mean by the Dark Eye?"

Master Hobbis's expression also became solemn, and he asked in a hoarse voice.

The blood-colored vertical eyes on Master Leo's forehead blinked slightly, and his eyes were invisible, but this "dark eye" seemed to be able to replace his eyes, and he could see everything around him, and he seemed to be able to see things that were difficult for ordinary people to see, such as some illusions and the like. There is no way to confuse Master Leo with the Eyes of Darkness.

"The cultivation method of the Dark Eye. All you get in the Abyss Fort is a crippled cultivation method. So after all these years, can anyone in your Abyss Fortress cultivate the Eye of Darkness?"

Mage Leo spoke suddenly, but instead of answering Hobbis's question directly, he mentioned the cultivation method of the Dark Eye.

Mage Hobbis was naturally clear about this, so he sneered and continued, "Hehe, Master Leo. It's no secret that the cultivation method of the Dark Eye is indeed incomplete, and the cultivation method of the Dark Eye you get should also be incomplete. However, you are indeed powerful, and you are actually able to create an original method of cultivating the Dark Eye by yourself, so as to cultivate the Dark Eye to the fullest. ”

Mage Hobbis's gaze clearly revealed curiosity about Master Leo's original Dark Eye cultivation method.

A smile appeared on the corner of Mage Leo's mouth and said, "Sixty years ago, I came to the Abyss Fortress and exchanged some treasures for some of your dark spells. This time, I have come to give you treasures as well. But this time, I'm giving you my original cultivation method of the Dark Eye!"

"Your original Dark Eye cultivation method?"

A hint of fiery color flashed in Master Hobbis's eyes, and if others said that he had created the cultivation method of the Eye of Darkness, Master Hobbis would definitely disdain it.

However, it was Mage Leo who said this, this weight is very unusual, Master Leo is recognized, he has cultivated the Eye of Darkness to the fullest, and even relied on the Eye of Darkness to kill the seventh-level spellcaster in Osmu.

With such a record, everyone will no longer doubt Master Leo's Dark Eye, and Master Leo's original Dark Eye cultivation method is naturally extremely valuable, comparable to any treasure.

Thinking of this, Mage Hobbis couldn't help but ask, "Master Leo, what do you want to exchange the cultivation method of the Dark Eye for?"

A slight smile appeared on Master Leo's face, and as expected, his Dark Eye showed great strength, and for the Abyss Fortress, his original cultivation method of the Dark Eye was the most attractive.

So, Master Leo gently put his finger on the table and said in a deep voice, "You need to ask my student, Master Merlin, to go to your library and choose any dark spell above the second level, this is one of them. ”

"Second, the Pandora magic energy in your Abyss Fortress and the cultivation method of the Heart of Darkness will also be passed on to Merlin, and Merlin will also need to use your Dark Realm to cultivate for a few days, and it is best to cultivate the Heart of Darkness during this time. With these two conditions, if you agree, I will give you my original cultivation method of the Dark Eye!"

After Master Leo finished speaking, he quietly waited for Master Hobbis's answer.

And Master Hobbis's face was also a little gloomy, and his eyes kept falling on Merlin's body, he didn't expect that this time Master Leo used the precious Dark Eye's cultivation method to exchange it for Merlin in exchange for spells and the Pandora magic power of the Heart of Darkness, so he also wanted to see what was so special about Merlin that he actually made Master Leo go to such great lengths and pay such a big price to help Merlin.

After a long time, Master Hobbis spoke: "The first point, Merlin can choose from the dark spells above the second level, but he has to sign a contract, and he can't pass on these spells. ”

"No problem!"

Mage Leo nodded, when he came to the Abyss Fortress in exchange for a spell, he signed a contract and must not be passed on. The most crucial condition he put forward is the second point.

"On the second point, Master Leo, you should know that the Heart of Darkness is unique to my Abyssal Fortress and has never been passed on. ”

Mage Hobbis said slowly, but his eyes were fixed on Mage Leo.

"Hehe, Master Hobbis, it's true that the Heart of Darkness is not known, but how is the Heart of Darkness compared to the Eye of Darkness? ”

"The Heart of Darkness is of course very important, but you can also sign a contract with Merlin so that he can't pass on the Heart of Darkness, and even I can't cultivate, so that only Merlin can cultivate, but you have obtained the cultivation method of the Eye of Darkness, maybe you have a talented and persevering spellcaster in the Abyss Fortress, and if you get my cultivation method, you can also cultivate the Eye of Darkness successfully. ”

The blood-colored vertical eyes on Master Leo's forehead emitted a strange blood-colored light, and after he finished speaking, he stopped speaking and quietly waited for the result of Master Hobbis.

After a long time, Master Hobbis stood up and said to Master Leo, "This matter is very important, and I need to go to someone to discuss." ”

"It's okay, we can wait. ”

Master Leo's face looked very calm, and he said lightly.

Mage Hobbis nodded, and then walked into the depths of the hall, leaving through the other side of the passage, in this extensive underground, if you don't stay for a long time, you don't know where these passages lead, and if the Abyss Fortress is in danger, many spellcasters can quickly leave through these complex passages.

The Dark Spirit Domain is very mysterious, even entering and exiting the Dark Spirit Domain can only be teleported by the rune array, and it is very difficult for outsiders to find the Dark Spirit Domain, and the Abyss Fortress is a huge and complex underground passage built underground, making it difficult for outsiders to figure out these passages.

Therefore, it is difficult for these spellcaster organizations to be conquered at once, which is one of the main reasons why the caster organizations can be inherited for thousands of years without being destroyed by a devastating blow.

"Mentor Leo, what is the Heart of Darkness?"

After Merlin saw Mage Hobbis leave, he couldn't help but ask Mage Leo, from the conversation between Mage Hobbis and Mage Leo just now, Merlin only knew that the Heart of Darkness was a kind of Pandora magic energy, which was unique to the Abyss Citadel, but what it was, Merlin was confused.

Mage Leo explained calmly, "The Heart of Darkness is a type of Pandora magic of the dark type, but unlike the Eye of Darkness, the Heart of Darkness is only a secondary Pandora magic power. If you cultivate the Heart of Darkness, you will be greatly more powerful than many amplified spells when you cast any Dark spell. Moreover, if you are attacked by a dark spell yourself, the heart of darkness will automatically solve it, and as long as it is not a dark spell that is ridiculously strong, it will not pose any threat to you. ”

After a pause, Master Leo's expression became solemn, and he said in a deep voice, "If that's all there is, then I won't let you cultivate the Heart of Darkness." The biggest benefit of cultivating the Heart of Darkness is actually when you build a Level 4 spell, and at that time, the Level 4 Dark Spell you build will be able to be fused with the Heart of Darkness, and the power of the spell will become extremely powerful. ”

"Actually, I have occasionally seen from some ancient texts that three thousand six hundred years ago, when spellcasters were at their peak, those ancient and powerful spellcasters, every spell would be fused with Pandora's magic energy, and the spells after fusion, even if they were first-level spells, could have terrifying power. However, time has passed, the heyday of spellcasters has passed, and even most of the Pandora magic energy has been lost in the long history, not to mention the method of Pandora's magic energy and spell fusion? ”

Master Leo let out a long sigh, and there was a lot of emotion in his tone.

However, Merlin's heart moved slightly, it turned out that three thousand six hundred years ago, in the heyday of spellcasters, Pandora's magic energy could be fused with spells, even if it was a first-level spell, once it was fused with Pandora's magic energy, it could have terrifying power.

Merlin thought of his Pandora's magic energy Collapse Fire, this Collapse Fire has a total of three forms, and the third form of Collapse Fire seems to be able to merge with the seventh-level spell, which also confirms from the side what Master Leo just said, which is likely to be the truth.

Just when Merlin wanted to ask again, Mage Hobbis returned to the hall, and behind him, there were two powerful spellcasters, who came to the hall without saying a word, squinting slightly, and constantly looking at Merlin and Master Leo.

The atmosphere in the hall suddenly became a little dull. (To be continued......)
