However, just as Lin Li was walking towards the tower, he suddenly saw a street exit not far away.

"Master Sain, ...... are you" Lin Li looked at the powerhouse pillar of the Marfa family, and his embarrassed appearance made people a little unrecognizable. Looking at Seon's stray hair, stained magic robes, and the gems of the staff in his hand had dimmed, it looked as if he had just gone through a fierce battle, even more embarrassed than when he was besieged by the green dragon before. Could it be that the people of the Dark Blade can't wait to strike at him?

After seeing clearly that it was Lin Li who spoke, Sean let out a sigh of relief and said with a wry smile: "Magician Ferrey, when did you arrive, and didn't you encounter anything on the way?" ”

Lin Li was a little confused, he originally thought that Sein was attacked by the Dark Blade's people, but when he asked himself what he meant, it didn't seem to be the case. He looked at Sein's appearance and asked suspiciously, "What did you encounter?" Aren't you with anyone else? ”

The entire Sky City has become a dead city, since it is not for the Dark Blade and the elves to attack, with the strength of Thane, even if he touches the magic mechanism by mistake, he should not be forced to be so embarrassed. And looking at Sein like this, it was obviously not caused by some magic mechanism, judging from the chaotic magic fluctuations and the dim staff, it was obvious that there had been a difficult battle.

Sein looked around and found that there were only himself and Lin Li here, so he sorted out his image and said with palpitations: "I don't know what's wrong with that teleportation circle, I haven't seen anyone else since I teleported here." As for the way I look, you may not believe it when I say it, because I have encountered a group of resentful spirits. ”

"Wraiths?" Lin Li was indeed a little unconvinced. Wraiths are also one of the more common undead creatures, and although they are nearly immune to physical attacks, they are naturally afraid of light and magic. And Sean is a real legendary mage, if he encounters a group of resentful spirits, why would he be so embarrassed. Not to mention a legendary mage of the twenty-first level, it is an ordinary archmage, as long as he deals with it carefully, he will not be forced to be so embarrassed.

Sein shook his head and said helplessly: "Don't say you don't believe it, even I don't believe it now." I don't know who designed this castle in the sky, but I walked farther and farther along the streets, and I was just about to fly directly over those buildings when I was besieged by a group of resentful spirits. If it were an ordinary resentful spirit, it would naturally be easy to deal with, but among that group of resentful spirits, there were actually a few who already had entities! ”

Hearing Sain's words, Lin Li couldn't help but show surprise on his face while glad that he didn't fly around. The resentful spirit itself is formed by the condensation of a resentful qi, and its form is a kind of ethereal existence, and it is precisely because of this that it has the ability to be almost immune to physical attacks. But this insubstantial form, in addition to being an undead spirit will be restrained by the holy light with a purifying effect, the damage of magic to it is also extremely high, and even sunlight, flames, these environments that can be seen everywhere, will cause irreparable damage to the resentful spirits, in fact, many resentful spirits that have just condensed into shape, are the sunlight and flames that can be seen everywhere turned into ashes.

Resentful spirits, skeletons, these are the two lowest level of undead creatures, their advancement, and it is also the most difficult among the undead creatures, so the skeleton king of the Shadow Valley will shock the entire Anriel world when he is promoted, this is not just a matter of luck, to some extent, it can even be described as a miracle, with strong strength in life and a perfect growth environment after death, all kinds of factors are indispensable.

It is no exaggeration to say that the probability of a resentful spirit forming an entity is similar to that of being killed by a meteorite while walking down the street...... And now the situation of Sain is almost equivalent to walking on the street, but being hit by dozens of meteorites at the same time!

You must know that the resentful spirit forms an entity, which is almost close to the legendary level...... Lin Li was very sympathetic to Sain...... While replenishing the magic power of the staff in his hand, Sain said with palpitations: "It's really terrible, at least two of the group of resentful spirits besieging me have legendary strength, and the strength of the other resentful spirits is also quite terrifying, if I don't have a little luck, I'm afraid there will be big trouble this time......"

Hearing Sain's words, Lin Li couldn't help but show surprise on his face while glad that he didn't fly around. The resentful spirit itself is formed by the condensation of a resentful qi, and its form is a kind of ethereal existence, and it is precisely because of this that it has the ability to be almost immune to physical attacks. But nothing in this world is perfect, this form without substance, in addition to being an undead will be restrained by the purifying holy light, the damage of magic to it is also extremely high.

In this case, no matter whether the resentful spirit is level five, ten, or fifteen, it will not change in the slightest. Only when the strength of the resentful spirit is close to or even reaches the legendary level, it is possible to condense the resentment on the body into substance, and then the resistance to magic will also increase.

However, it is this void form of the wraiths that makes them have a huge chasm that is difficult to cross in terms of improving their strength. The most important source of power for undead creatures is the soul fire transformed by the soul after death, so there is a very quick way for undead creatures to increase their strength, which is to devour the soul fire of other undead creatures.

Resentful spirits condensed by resentment do not have soul fire of their own, and they cannot increase their strength by accumulating strength, nor can they strengthen themselves by devouring other soul fires. Even with the passage of time, the resentment on the resentful spirit will gradually dissipate, and its strength will only get weaker and weaker, how can it reach the legendary level and condense the entity.

Not to mention in the Anriel world, even when he was in the endless world, although Lin Li encountered a lot of resentful spirits, he really never encountered resentful spirits with entities.

"If the resentful spirit really has an entity, wouldn't its strength be close to the legendary level." Lin Li still said in disbelief.

While replenishing the magic power of the staff in his hand, Sean nodded and said, "Yes, among the group of resentful spirits besieging me, there are indeed two of them with legendary strength, and the strength of the other resentful spirits is far beyond that of ordinary resentful spirits. ”

Hearing Seon say that there really was a legendary-level resentful spirit, Lin Li had to feel sympathy for his plight. Resentful spirits below the legendary level, no matter what kind of strength, are quite easy for mages to deal with. However, the strength of the legendary wraith can be reflected more than a simple level.

The legendary wraith, whose body can switch between the virtual and the real at will, has no weakness of fear of magic, and can definitely be said to be one of the most difficult undead creatures in the world. Even in the legendary land of the dead, where there are many undead powerhouses, the legendary-level resentful spirits will basically be the undead monarchs who dominate one side.

There was a slight sympathy in Lin Li's eyes, and he naturally couldn't hide it from Sain, but what else could he say about his unlucky encounter. He glanced back at the street where he came out, and said with some joy in his tone: "The other resentful spirits are good to say, especially those two legendary resentful spirits, which are really difficult for me to deal with all my strength, and I don't know whether to say that they are unlucky or lucky, but fortunately they seem to be confined to one area, which gives me a chance to get rid of them." ”

Wraiths are confined to one area! Lin Li was suddenly shocked in his heart, in fact, since Sein said that he had encountered resentful spirits, he was thinking about the origin of these resentful spirits, and he had to know that legendary resentful spirits with entities were almost impossible under normal circumstances. What's more, Sky City has escaped into the rift of time and space for so long, and this more than 1,300 years is enough for any resentful spirit to dissipate over time, let alone grow into a legendary resentful spirit.

Originally, for the High Elves, they were born under the Tree of Eternity, and their souls would return to the Tree of Eternity after death, which made them almost fearless of life and death, and they would not even have the slightest resentment when they died, and it was impossible for them to become resentful spirits in any way.

However, with the High Elves losing their war at the end of the Dark Ages, not only did they lose their supremacy, but even the High Elf Empress was killed and the Tree of Eternity was destroyed. In this case, it is impossible for them to have no resentment when their souls have lost their home, and it is not surprising that resentful spirits will be born after death.

However, what does it mean that the Wraith is confined to a fixed area? In Lin Li's opinion, there was a great possibility that it was because those resentful spirits were one with some kind of setting in the Sky City. In other words, those powerful resentful spirits are part of this Sky City, and although the Conquest of the Demon Pattern has not been activated, they can still get power from the Sky City.

Many of the High Elves, who were already at the end of their rope, chose to turn their backs on their glory and instead study necromancy, which they once hated the most. Nophil's former owner, as well as the legendary Lich of Deathscar, are High Elves who stayed in the world of Anriel and secretly studied necromantic magic. Although they all made a secret study, either in the catacombs or deep in the mountains. But who knows if those High Elf leaders are actually studying necromancy like them.

The High Elves' magical talent is so high that even the various races that are brutally ruled by the High Elves are not allowed to admit that the High Elves are simply made for magic. Necromancy, like any other magic, is not difficult for the High Elves at all, the only difficulty is only the psychological cleanliness level.

Lin Li himself has come into contact with the High Elves who study undead magic, and those crazy people will do everything to the extreme if they don't do it, but they do have that ability. And those two High Elf Lichs are just ordinary High Elves who secretly study undead magic, so what about this city in the sky?

Now, in this sky city that has been missing for more than 1,300 years, there are resentful spirits, and they are still legendary resentful spirits, so Lin Li has to revise his original thoughts.

Originally, in Lin Li's opinion, although this sky city was built by the high elves with the strength of the whole clan, after all, after so many years, it was already a dead city. The so-called defensive force is probably only magic traps or traps and the like. Although the High Elves have reached the pinnacle level of that era in all aspects of their skills, they are not vegetarians themselves. With the strength of his own sect masters, it will not be too difficult to deal with those magic organs, not to mention that they can be captured.

In fact, from coming to Sky City through the teleportation circle, and then walking all the way to the central tower without incident, it proves that Lin Li's self-confidence is not arrogant. Along the way, all kinds of cleverly set up and even vicious magic mechanisms were completely hidden in front of him. Although this did not make him let his guard down, there was indeed a feeling in his heart that everything was under control.

But now, the appearance of the legendary resentful spirit has forced Lin Li to re-examine this dead city. Although he didn't encounter any powerful obstacles along the way, he was about to enter the central tower next, and what was waiting for him was probably not just a magic mechanism.

Seeing the thoughtful look on Lin Li's face, although Sein had already finished his business, he waited there quietly and did not say anything to disturb. Because he knew very well in his heart that the four forces that entered the Sky City seemed to be the strongest of the elven race, and the strength of the Dark Blade was not far from the elf race, but if he wanted to talk about the understanding of the sky city, I am afraid that no one could compare to the young man in front of him.

"Master Sein, what do those two legendary resentful spirits ......look like," Lin Li came back to his senses and asked Sein, who was waiting next to him.

"It seems to be the appearance of a high elf, and the bodies of the other wraiths are not very solid, so the appearance is also very blurry." After Sain answered, seeing that Lin Li just nodded, he hesitated and asked, "Magician Ferrey, I don't know what your next step is." This castle in the sky is designed like a huge labyrinth, and even if you have a map in your hand, you don't know if you will encounter anything. ”

Lin Li smiled when he heard this, it was obvious that Sein had suffered a lot from the legendary resentful spirit, and he had appreciated the danger of this sky city, but he was embarrassed to say that he would follow him directly. He raised his head and looked at the tower in the center of the square, and he didn't hide it, and said frankly: "Did Master Seon see that tower, according to my speculation, inside that tower, it should be the hub that controls the entire sky city." If you don't mind, why don't we go over and have a look. ”

Sain turned his head to see the huge tower in the center of the square, which naturally no one would ignore. Although he had no solid evidence, he could guess that the central tower should have played a very important role in the city in the sky based on its size and location. Therefore, after teleporting here, he also aimed at this tower, and even when he walked farther and farther through the labyrinthine streets, he wanted to jump directly over the blocking building and come directly to the tower.
