However, Lin Yun was quite surprised that the fifth ancestor survived. The other party paid such a great price and successfully tricked Agalon and the others into the trap. It would be difficult to think about it after entering the Nightmare Kingdom.

Lin Yun felt a little trouble when he thought about how to save Agalon and the others.

It is very easy to enter the Nightmare Kingdom. Lin Yun knew that more than a dozen ways could enter the Nightmare Kingdom, but if you want to escape after entering, you must be fully prepared.

After entering the Kingdom of Nightmare, the natural half-planes should be blocked and cannot be opened in the Kingdom of Nightmare. In that world that seems to be virtual and illusory, everything may be fake, but equally, if you really die inside, it will be really dead.

After thinking about it for a moment, Lin Yun seemed to remember that he saw something at the undead auction last time. Lin Yun didn't know what was inside the box, but he remembered that there seemed to be a box with all the special symbols on the surface.

The meaning of that symbol is to seal the power of nightmare, similar to the effect of spiritual protection. I glanced at it last time and didn't care. Now when I think about the things about the Nightmare Kingdom, Lin Yun suddenly remembered that the symbol, I had seen it before, if nothing unexpected happens, the box contained the things left by the Nightmare Lord. The biggest possibility is the parts somewhere on the Nightmare Lord's body.

The bones and soul fragments of the Lord of Nightmare are combined to open the gate of the Nightmare Kingdom. With this key, you can get back after entering the Nightmare Kingdom, but this is just a possibility...

But more importantly, something else is needed.

The cursed person who lost his soul walked forward in the black nightmare, and the curse of eternal life could not sleep for a moment...

This is a sentence I have seen before. Lin Yun had a headache. If he wanted to come back, he had to use the power of others to lose his soul. The cursed person who lost his soul was the ancestor of the vampire.

Only the thirteen ancestors of vampires are creatures who have no souls but live well. Legend has it that their souls disappear because of the power of curses, and they can live eternally like lichs. But they will never get a moment of sleep.

According to legend, in the Kingdom of Gods and Demons of the Nightmare Lord, the servants who managed the kingdom were the thirteen vampires of that year, because they would not be affected by the power of the Nightmare Kingdom. In order to prevent everything in the Kingdom of Nightmare Lord from becoming desolate, someone must do some rough work that the Nightmare Lord is unwilling to do.

So he used his power to create the thirteen vampire ancestors.

This is just a legend, and no one is sure of the real situation, because the power of the Nightmare Lord itself is full of mystery. However, the vampire ancestor will not be affected by the power of the Nightmare Kingdom, this has been confirmed.

If there is a correct method and possess the key to the Nightmare Kingdom, the probability of the vampire ancestor coming out of the Nightmare Kingdom is the greatest. As long as you die completely in it without any accident, you will definitely escape.

After the future undead plane was conquered, all the Thirteen Vampire ancestors were caught, and they were put on the reins like hunting dogs, allowing them to assist in exploring the Nightmare Kingdom.

Those crazy mages have also developed a way to freely enter and exit the Nightmare Kingdom. Many mages even went to the Nightmare Kingdom to find inspiration...

The records left by these people are full of things specifically about the Nightmare Kingdom. Lin Yun knows how to get in and out and how to get there. But the most critical point now is how to catch a living vampire ancestor...

This living vampire ancestor is like a guide dog, or a mark. If you want to leave the Nightmare Kingdom, the best way is to use a living vampire ancestor as the coordinates...

It is not a particularly difficult problem to kill a vampire ancestor with a lower strength. Seven or eight vampire ancestors who ranked high have fallen. It is no problem to find news later to kill one. But those who want to catch the alive...

This is a big problem. Lin Yun kept scratching his head, and large pieces of sparks kept popping up on his skull.

"Forget it, let's go and see what's in the Undead Auction House first. Can you get a complete key before talking about it..."

When he arrived at the auction house carved from huge obsidian, Lin Yun transformed into a human appearance again, driving the power of the Start Chapter to wrap his body in a layer of black mist.

When I entered the auction house again, there were still many undead people in the auction. This time, the auction items were obviously not as good as the last time. After Lin Yun came in, the skeleton with a broken felt hat took the initiative to greet him and took Lin Yun to the upper level without saying a word.

When she saw Lilith again, she was lying on the table and writing something quickly. The Book of Forgotten floated in front of her. In addition to the Book of Forgotten, there were more than a dozen animal skin books floating in front of her. These books were constantly flipping, as if Lilith had encountered some difficulties.

When Lin Yun walked in, Lilith immediately split out a few thick octopus tentacles, carefully rolled up the books, and put them all in their original positions.

"Oh, my dear Lord Human, you are still alive. The plane of the undead has not been very calm recently. I thought you had fallen, and that was the most unfortunate news.

It’s so great to see you again. Our transaction can continue. Do you still have the Klingon spell? The Book of Forgotten has recently recorded a lot of things that you may be interested in. Do you want to take a look?"

When Lilith saw Lin Yun, she immediately expressed her enthusiasm with an aria, and even used a move to bring Lin Yun a huge seat that was more than three meters high.

Lin Yun's expression was a little strange. It took only a long time since we met, and Lilith was like taking the wrong potion...

"Ah, am I wrong? Aren't the strong people in humans called you? I have recently studied knowledge about humans. I have to say that many of human things are much stronger than the undead. I am terrible creativity that shocked me. It is a race favored by fate, although most humans are too fragile..."

Lilith still spoke in that minstrel-like aria, and Lin Yun sighed.

"Okay, Lilith, can we continue our previous transaction? All the remaining fragments have been found?"

Lilith pushed her single lens, stretched out a tentacle, raised her from the stone stand on the side, and took off a pitch-black stone box. The surface of the box was carved with a large number of strange patterns, full of magic patterns with the characteristics of the undead plane.

Lilith opened the stone box, and the incredible aura of light burst out from the stone box. The soft light power turned into a circle of faint halos, covering the stone box. As time passed, the halos slowly expanded. It seemed to be completely unsuppressed by this obsidian building.

Lin Yun glanced at the fragments in the stone box and nodded slowly. The fragments were placed in the box, but one of them was missing, and the shape was exactly the one I got last time.

Although it is broken, it doesn't matter as long as there is no lack. This thing is one of the components of the Book of Death. As long as there are specific methods, it can be easily recovered with all the fragments.

Moreover, the purest aura of light cannot be disguised. At least no one in the undead plane has such ability, especially the characteristics of not being suppressed by obsidian buildings, which further shows that this is the real thing.

Lin Yun threw out a space ring for Lilith.

"There is the arranged plane path inside. I made the plane path into a special magic weapon. No matter where the other party arranges the plane path, I just need to assemble it according to the method recorded in it. After the plane path is arranged, it will be completely stabilized and can no longer be moved.

According to our transaction, let the buyer determine this location by himself. I won’t know, okay?”

Lilith pushed her glasses, held the space ring and looked at it for a few seconds. She nodded decisively.

"No problem, Your Excellency Humans, you are more trustworthy than recorded humans. It seems that our transactions are very pleasant. We can continue to trade."

Lin Yun put away the box and nodded.

"Okay, Lilith, we can continue trading. I want things about the Lord of Nightmare, preferably the bones and soul fragments of the Lord of Nightmare. We can discuss the price of the transaction."

Lily Ribbon kept flipping the Book of Forgotten in front of her with a smile, and soon found what she wanted, but when she looked at Lin Yun, she seemed a little surprised.

"Your Excellency, do you want to go to the Kingdom of Nightmare? Entering the Kingdom of Nightmare will inevitably encounter permanent destruction. Even the King of the Undead is unwilling to enter that kind of place. According to the Book of Forgotten, no one can come out again except for a special creature.

If you want to save those humans who have fallen into the Nightmare Kingdom, I advise you to give up. Humans cannot enter the Nightmare Kingdom to save people..."

Lin Yun was not surprised that Lilith knew about this. The special function of the Book of Forgotten can make many people forget what they don’t want to know, and generally this kind of information can be used for transactions...

"Hey, sir, aren't you surprised why I knew it? Oh, it's boring. It turns out that you knew it a long time ago. However, as a fair deal, I must remind you that your thoughts are completely impossible. Even if you get what you want and can enter the Nightmare Kingdom, you will not be able to escape from it again. There is eternal destruction..."

Lin Yun nodded.

"I know these things, a Klingon spell, exchanging the bones and soul fragments of the Lord of Nightmare, can I trade them?"

Lilith covered her forehead, as if she was a little distressed.

"What a stubborn guy. Humans are really very stubborn. Well, I do have a bone and soul fragment of the Lord of Nightmare here, but you know.

The Nightmare Lord has a special body. He doesn’t have a few bones. The Nightmare Lord fell on the undead plane, and basically all his bones disappeared. The remaining part of this skull is the only piece we have obtained.

This is the most precious thing, sir, do you think a Klingon spell is enough? Our transaction is fair enough..."

Lin Yun shook his head gently.

The Lord of Nightmare is indeed quite special. This guy is the only guy among the gods and demons who have no fixed body. He is similar to a semi-ghost state, but he still has bones. If it weren't for this state, the Lord of Nightmare wouldn't have escaped to the undead plane when he was about to die.

Escape to the undead plane because he wanted to use the power of the undead plane to recover. It was not difficult for his body to transform into a undead creature. It was just a pity that the injuries he received were the broken souls of gods and demons, and it was useless to reach the undead plane...

The bones of the Lord of Nightmare are relatively rare, but if you want to say that only one piece is left, it is a bit exaggerated. Lin Yun remembers clearly that the Lord of Nightmare's skull is composed of seventeen bones, eleven of which are turned into ashes and dissipated. Six remaining pieces are all in the undead plane.

One of them turned into the Death Knight's mount nightmare, and the remaining five were left, and the person who kept his original appearance and could destroy the skull of the Lord of the Nightmare. It almost did not exist in the undead plane, at least none of them knew how to destroy the skull of the Lord of the Nightmare.

After all, it is the skull of gods and demons, something almost immortal. This undead auction house, Imir said, seems to be the industry of the greedy lord of the undead plane. This greedy lord Lin Yun has some impression. In the records, it can be regarded as the God of Wealth in the Undead plane. The ability to plunder wealth is definitely the first in the undead plane.

It seems that there is only a vague record. No one has seen what kind of creature this greedy lord is. What kind of appearance and strength, this guy has never participated in a war, and it seems that he has no territory. However, the undead lords all seem to know that this greedy lord is not easy to mess with.

If this greedy Lord only has a skull of the Nightmare Lord, Lin Yun really doesn't believe it at all.

The five keys made in the future all come from the undead plane, and it seems that it is not difficult to find these five skulls. The last skull turned into a nightmare war horse. I don’t know why it was not killed by those crazy mages.

As for the soul fragments of the Nightmare Lord, there are more. After all, he is a guy in a semi-ghost state, and the souls of gods and demons are broken and dead. The number of residual soul fragments is very large, far more than the number of skulls.

"A Klingon spell, exchange for a skull of the Lord of Nightmare. Soul fragments are fine if you are willing to trade with them, and it doesn't matter if you don't trade. After all, the Lord of Nightmare has a relatively large number of soul fragments. I only need to spend a little effort and it's easy to find them. For example, if I remember correctly, there seems to be a Ghost Canyon, and there seems to be a three-fork intersection of the Styx River..."

Lilith stared at Lin Yun tightly.

"The soul fragments in the Ghost Canyon have long disappeared. The three forks of the Styx River, terrible guy, how do you know where there will be the soul fragments of the Lord of Nightmare...

No, at least two Klingon spells can’t be missing anymore!”

Lin Yun continued to shake his head.

"Lilith, greed is the greatest original sin. I only have this last Klingon spell left. This is a very fair deal. I know where to get the skull of the Lord of Nightmare, but it's too troublesome. Trading with you is the most time-saving way.

In fact, if we hadn't traded quite happily, I would have found other devil clerks to trade, and I believe they would be very happy to trade two things that had no effect on themselves in exchange for a precious Klingon spell.

Besides, it really doesn't work. It's not impossible for me to trade with the Lord of Greedy, but I think it's definitely not particularly pleasant to trade with that guy, so do you understand?

What I want is not only you, but what you want is only I. This is unequal. According to value, I will give more than you!”

Behind Lilith, dozens of tentacles were dancing constantly. Lilith opened her eyes wide and stared at Lin Yun tightly. After more than ten seconds, she waved her hand dejectedly. A tentacle flew out and took off a pitch-black obsidian box from the top of the stone rack.

"Well, the greedy devil, damn, the most greedy devil I have ever seen, the most greedy devil, the most trading devil is not as good as you. You are such a terrible guy, I think you can definitely trick a devil into his territory from the hands of a devil.

A Klingon spell, the skull and soul fragments of the Nightmare Lord you want, are all here.

However, as a premise of trading, I still want to remind you that you have obtained this thing and entered the Nightmare Kingdom, and you have no way to escape. Although I am more capable of trading than the devil, I don’t want you to die in the Nightmare Kingdom…”

Lin Yun smiled and said nothing. He held a quill and quickly signed the transaction contract prepared by Lilith. After the contract was reached, Lin Yun wrote a Klingon spell on the Book of Forgotten.

After looking at the Klingon spell on the Book of Forgotten, a smile appeared on Lilith's face. The importance of the Klingon spell to her is equivalent to the wizard's understanding of the rules, and it is necessary to advance. Although a Klingon spell can only be used once, after using it, this Klingon spell will be completely scrapped.

But in this era, although there are not many Klingon spells that have not been used, there are also many. They are all unused Klingon spells that have been excavated in the future...

After all, only rare things are of higher value, and the undead will understand this truth...

After getting what he wanted, Lin Yun opened it and took a look. There was a bone that was only the size of a palm. It often seemed to have no characteristics, but when he stared at the bone, he felt that his spirit was a little dazed. The longer he stared at, the stronger the feeling would be, and even the soul began to be affected.
Chapter completed!
