Connecting the clues obtained before, it is certain that the undead originally appeared in this underground city, and then appeared in the later Aladdin Imperial Capital by digging upwards, and launched a series of raids, causing the then powerful empire to collapse overnight.

Where there are undead, there must be dark wizards or lichs. So, this underground city has existed in the world for so long, why hasn't this dark wizard commanded the undead to attack until now, or is it that the dark wizard can't leave this place at all?

Perhaps it is possible to make a bold guess that someone used their strength to seal the lich or dark wizard, along with the entire city, and did not hesitate to sink the city into the ground for fear that the seal would be broken by others.

Then, if it's just a dark wizard, there is no need to bury the whole city with you, nine times out of ten it is a lich, and this lich is very strong.

What era is this city a product of?Who is the lich hiding here?Who is it that sealed him?One unsolved mystery after another haunts Kenshin, arousing his great interest, and he and the black dragon continue to walk the streets beyond the palace, hoping to find some key clues.

Kenshin's Death Spell turned countless undead into bones, losing energy support, and these bones that had been silent for thousands of years melted with the wind as soon as they came into contact with the air, leaving only a thick layer of bone powder on the ground, leaving deep footprints on it.

This half of the city is too big, the two of them searched for three days, and finally found a relatively large building complex in the center of this half of the city, there is a huge golden signboard at the door, but with the erosion of the years, these gold has become very light, there are a few characters on the signboard, but Kenshin can't understand it, only hope for the black dragon.

"The Warlock Research Institute, it turned out to be the Warlock Research Institute, how is this possible. The black dragon muttered to himself in distraction, his face full of horror.

What is it? Kenshin was stunned for a moment, and looked up at the signboard on it, could those characters be the Warlock Research Institute? What does this mean?

Ben Long remembered, this is the lost city of Cartier, no wonder it feels so familiar, I can't think of it, I really can't imagine that the holy capital, which was called the city of miracles, has been buried in the ground for thousands of years, no wonder no one has been found. ”

The black dragon patted his head violently, and the chaotic memories finally began to become clear.

"The Lost City, the holy capital of Cartier, strange, as if somewhere had you heard it. Kenshin chanted a few times in confusion, and motioned to the black dragon to explain.

"You don't even know the Holy Capital Cartier?Are you a human?" the black dragon's eyes widened when he heard this, and he explained, "As the name suggests, the Holy Capital is the most sacred city among human beings, and it is also the first city among human beings. ”

Kenshin suddenly came to his senses: "Longinus, by the way, it turned out to be this holy capital, why is it so familiar to me, then what's going on with this Warlock Research Institute?"

"The Warlock Research Institute is equivalent to the current Mage Guild, which was founded by the legendary * Master Longinus at that time, but with the decisive battle with the undead, all this, including the Holy Capital, has been annihilated in the long river of history, and there are few humans left who can survive at that time, they are all hiding and stealing, no one is looking for the missing Holy Capital, and when they recuperate for a long time and live in this land again, the prosperity of the past is long gone. ”

"Wait, hearing you say that, isn't this the place where Longinus sealed the dark wizard?" Kenshin's heart was beating wildly, those were three dark wizards.

The black dragon sighed: "After eight thousand years, there are still undead, which means that the dark wizard at that time is not dead, and it was not until two thousand years ago that the undead began to attack Aladdin, that is, the seal laid by Longinus began to loosen two thousand years ago, although the dark wizard has not yet been born, but I am afraid it will not be trapped for long." ”

"Then do you say that Longinus is dead or alive now? Even the dark wizard is alive, and he, the legendary* master, should not die. Kenshin asked with luck.

"It's hard to say, maintaining the seal requires constant energy consumption, now that the seal has been weakened, it seems that even if Longinus is still alive, I'm afraid the oil is running out, and after eight thousand years, the dark wizard of the year has already been promoted to a lich. ”

The black dragon said, his face suddenly changed greatly, and he exclaimed: "No, before the decisive battle, Longinus was the main god-level strength, and it was stronger than that God Exterminator Ares, in the era when Longinus existed, the two worlds of gods and demons did not dare to touch the continent at all, how could they be stumped by a few dark wizards?"

Kenshin was taken aback: "You mean, it wasn't the dark wizard who caused the apocalypse at that time, but the lich?"

"Yes, it must be a lich, and it is also a lich at the level of the main god, the reason why Longinus is called a legend is because his magic is very powerful, second, his understanding of the magic array, the magic array he laid out, can seal the main god who is about the same strength as himself, and the third is that he himself is not a simple mage, but a demon and martial arts double cultivator, and most importantly, this guy is even more perverted than you, he has an eight-system magic physique. ”

"What? Eight Magical Physiques, Ice and Thunder Didn't They Disappear Ten Thousand Years Ago?"

"So what? Longinus's fame was earlier than Thor and the God of War, he mastered these two types of magic in ancient times, and the war of the gods 10,000 years ago had no effect on him at all. The black dragon pursed his lips, Longinus was not only a dual cultivator of magic and martial arts, but also proficient in earth, water, fire, wind, light, darkness, ice, thunder, and eight kinds of magic.

"He became famous earlier than Thor, so why didn't he participate in the war during the bloodstained period of the hundred tribes?"

Kenshin was very puzzled, according to his inference, the two wars of the year should have been driven by someone behind the scenes, and Longinus was a strong man at that time, and there was no reason for the person behind the scenes to let him go, and now in retrospect, it seems that in that era of tribulation, only the human race was not affected.

"I don't know, when the war happened, Uncle Long was still fighting in another world, but according to Ben Long's understanding, Longinus led all the races to migrate to the Silver Moon Continent back then, and did not participate in those two wars, maybe he discovered something. ”

"Demon and martial arts double cultivation, eight-system magic physique, people are legends in the world, but I only have the title of a god destroyer, and I am endlessly hunted down, his grandmother's is also a human, why is the difference so big?" Jian Xin muttered unhappily.

The black dragon sneered disdainfully: "Don't expect to compare with him, your master may still have a chance, Longinus's strength is very taboo even for Lord Dragon God, and he is known as the strongest person in the human race." ”

"I'm rubbing, you damn broken dragon, it's only been a few years since the master's debut? Give the master a thousand years to surpass him. Kenshin replied indignantly.

Heilong didn't take his words to heart at all: "Okay, let's talk about it in a thousand years, what should I do now? Do you want to go in?"

"Nonsense, since you're here, why don't you go in, there must be Longinus's magic notes inside. Kenshin stepped forward and kicked the gate away.

"Boy, have you thought clearly, the lich of the year made Nenglonginus even seal himself together, and his strength is definitely at the main god level, and now I don't know what realm to go, with you and me, we are not opponents at all. ”

"Cut, are you scared?" Kenshin looked at him with disdain.

The black dragon said angrily: "Fart, when Uncle Long was roaming the world, your kid was not born yet, and I have never seen anything that can make Uncle Long afraid in this life." ”

"I'm not afraid of the best, I'll tell you, since this matter has happened, we must take care of it, otherwise if those three damned lich break the seal, the world will face the catastrophe of destruction, and I'm afraid there won't be a second Longinus at that time." Kenshin said, and walked in first.

"It's easy to say, you can blow it after you can beat it. The black dragon followed behind him, muttering softly.
