When the necromancer in front of him dies, this castle has no defense.

After Du You finished summoning the Demon Flame Skeleton, he returned to this place, and the Demon Slayer Spirit had already traveled inside and out of the undead castle, all the traps had been found, and some special hidden locations had also been found.

"It seems that there are still some things left, let's go and clean them up, and if we find something valuable, we can transform them and bring them back. ”

Hearing Lin Yucha's words, Du You nodded, and found that other undead castles could not attack this position, so the three of them entered this castle. The character of a necromancer, how could he possibly trust anyone else. When building a castle, it is natural to build it outside the range of other castles, and it is still very far away.

Besides, if it was built directly in a very close place, let alone himself, the original owner of the castle would not allow it.

"It's all some, or something to do with undead creatures, it's useless. ”

Du You looked at the things around him, and through the panel identification, he found that the things here were basically useless. Especially for them, most of them are waste, and even if they take them back, it will be wasteful.

But when they reached the bottom floor, Du You's eyes narrowed.

Unexpectedly, this place is still a place to hide corpses. A large piece of the underground space has been hollowed out, and at a glance, there are corpses everywhere, both human and various animals, and many Du You can't recognize them.

It's not a question of how much you've seen, it's that a lot of the corpses have mutated. The corpses were piled up in this place, soaked in a special liquid that embalmed and penetrated the power of death.

With the passage of time, the corpses in this place become more and more special, and when they mutate to a certain extent, they will be transformed by necromancers using special means, and then directly summoned into powerful undead.

"The corpses at the top are all of the highest grade, and they are used to make high-level undead. The following ones are just used to provide death power. But in such a big pit, I don't know how many corpses there are, at least hundreds of thousands. ”

Du You nodded: "There must be, where did these guys get so many corpses." The northern mountains are so cold and snowy that there are simply not so many creatures for them to kill. "You don't have to think about it to know that this is definitely something they collected from the outside with special means.

"Don't waste it, we need a lot of Demon Flame Bones. Suddenly, Lin Yucha said.

Du You's eyes lit up: "Yes, we do need these things, you go out first, I'll summon here." "It's a terrible environment, and the air is filled with the smell of corpses and all sorts of other smells. If it were an ordinary person here, even if they weren't scared to death, they would probably be infected by all kinds of germs in the air and die.

The two sisters shook their heads, standing behind Du You, the master didn't leave, how could he leave because of a bad environment, this is not what a qualified servant should do.

Besides, Du You is also their lover, how can they leave their lover and run out to enjoy the fresh air.

Du You didn't say anything, he directly launched the summon, and the King of Bones was released one by one. Although there are many corpses, the actual range is not very large, after all, they are all piled up in this place. So soon, Du You's summoning was completed, but the magic power was consumed a lot. However, with the help of the dark spirits, the mana regained just as quickly.

It didn't take long for the corpses to be burned by the Soul Eater Demon Flame, and even the liquid was incinerated as well. The skeletons with the flames on their bodies stood up one by one, and there were many others below who couldn't stand up.

"Let's go, let's get out. Du You turned to leave, and the skeletons behind him were also following. A lot of skeletons are set together, but everyone is still moving forward. Big deal, just break a few bones.

When Du You and the three of them walked out, the castle was quickly occupied by a large number of demonic flame bones. A large number of demonic flame bones kept coming out, and those necromancers who saw this scene had a bad look.

"Bastard, they must have found the place where the corpses were hidden, can those corpses be used directly? ”

"We can't leave our hiding place to them, let's destroy it. ”

"Destroy, no kidding, is there still time or extra magic to do such a thing? ”

That's right, there are too many corpses in the hiding place, and because this place is so important, everyone has set up a lot of protection measures here, and no one wants to destroy this place at all, just to protect it.

As a result, even if they want to destroy this place, it will take a lot of time and consume a lot of mana. In this situation, who would spend their magic power to do such a thing, the gains outweigh the losses.

Besides, the number of enemies is already a lot, and how many can there be with these. They don't know the reality of the Demon Slayer. As the battle ensued, one castle after another was destroyed.

Every time a fifth-order necromancer appeared, they were wiped out one by one, and it didn't become a climate at all.

"Let's go over, that undead city over there is about to be destroyed. Lin Yushi pointed ahead and said.

But as soon as he finished saying this, the undead city suddenly exploded, and the cliff below trembled a few times, and finally collapsed. The stone shell and the large number of corpses inside fell downward, and the scene was extremely spectacular.

"It's better to be careful. Du You's eyes widened, and he looked at this madman-like necromancer in disbelief, how he would actually make his castle into a big bomb. If this guy holds out for a while and waits until the three of them pass, then they will be seriously injured if they don't die in this explosion.

That kind of explosion was not aimed at them, even if the sixth-order entered, it would definitely be affected.

Lin Yushi nodded: "Yes, I also think safety first." Lin Yushi directly forgot her previous words.

Soon, Du You came to the foot of the mountain and transformed the fallen corpses in front of everyone. A large number of demonic skeletons stood up. Those necromancers scolded their mothers in their hearts, who is this necromancer. Why is that guy who seems to be a dark attribute mage so much stronger than himself.

"No, we can't go on like this, let's join forces, or everyone will die. "They finally found out that it was not possible to go on like this, either unite or die here together.
