Generally speaking, the Mage Tower is forbidden to ordinary people, and if they encounter a grumpy Mage Tower owner, they will even be attacked by spells without warning - on Mage Towers, there are usually solidified spells, and the magic of these solidified spells is usually provided by the elemental pool of the Mage Tower. As long as the elemental pool is not depleted and the Mage Tower is not destroyed, it will be difficult for any foreign enemy to enter.

The Mage Tower is a place where magicians study magic and live, and for mages, it is also a war fortress, and it is said that the mage towers of the saint-level powerhouses can fly - this is true, but Hathaway doesn't know that those mage towers are made of some special materials, and as long as you have the money and ability, you can get the corresponding materials, even if you are a low-level mage, you can have such a mage tower.

The legend of Perseus Castle has been around for at least a long time in the Ortigar Empire, and although the Quincy family hasn't had a magician for a long time, there are still others who have explored it. But without exception, these people have gone and never returned.

And now, these people are not seen in life, and there are no corpses in death.

What Hathaway killed just now was just the lowest-level undead, they should have been transformed by the servants of the castle, if only these low-level goods, how could this castle become famous?

Just when Hathaway's heart was full of doubts, a cold breath suddenly emanated from the mage tower, and her body subconsciously retreated, and a golden bucket ring suddenly appeared on her body, repelling that breath.

Almost at the same time, the heavens and the earth suddenly changed. Overhead, there was a faint thunder, and pale lightning fell from the sky, and in the dense lightning, shadowy human figures appeared, and a thick rancid smell came to the face.

"Avril, what's going on?" Hathaway's eyes narrowed. Although these figures were not very clear, she was able to conclude that these were all undead, and they were all mid- to high-level undead.

"It's the Eye of the Netherworld!" From Avril's mind. Able to feel palpable excitement.

"The Eye of the Nether? Is it a component of the Fairy Garden? Hathaway asked rhetorically.

"Yes."

"The building blocks of the fairy garden. How can it be an undead attribute? ”

"Uh...... This is a misunderstanding. The reason for this effect is that the cold energy emitted by the Eye of the Netherworld is suitable for the growth of this undead creature. ”

As the two of them spoke, the figures had rushed out of the range of lightning. Appears in Hathaway's field of vision.

Skeleton Warrior!

Bands of skeletal warriors rushed towards Hathaway. Compared to the dozens of undead creatures just now. It's just pediatric...... At this moment, the first thought that came to Hathaway's mind was to get out of here.

No way!

She shook her head vigorously.

Although the number of these guys is considerable. But they were only intermediate, and Hathaway didn't think they could pose any threat to her.

The skeleton warrior was getting closer and closer, and she couldn't think much about it, so she raised her hand and threw it out. Now that Hathaway is already a great magician, how much has her strength increased tenfold compared to when she first built a first-level spell?

Although the Holy Light Judgment is still a first-level magic, it is cast by mages of different ranks, and its power is also very different.

This holy light ruling fell on the skeleton warriors in front of them, and it immediately showed great power, and more than a dozen skeleton warriors were immediately purified in a burst of light, and the soul fire was all annihilated.

For the undead, any kind of light magic is an opposing energy, and even if it is a first-level magic, it is not something that these skeleton warriors can resist. Although the undead have no fear and are not afraid of death, the attribute restraint is still that the nearby skeleton warriors began to retreat...... The ones behind had to move forward, and the ones in front had to dodge, and the formation of these skeletons suddenly became chaotic, and these skeletons all gathered together.

"Earth Flood Furnace!"

Taking advantage of this chaos, Hathaway completed a release of a third-level magic.

The temperature around him rose instantly, and under the feet of those chaotic skeleton warriors, a piece of magma suddenly appeared, and the endless high temperature broke out instantly, and those skeleton warriors were quickly swallowed by the magma, but in an instant, all the skeleton warriors in the magma range were shattered, and none of them escaped. The entire spell lasted for about fifteen seconds, and at least two hundred or so skeleton warriors were engulfed in magma...... Later, the skeleton warriors, who were almost always unable to stop, rushed into the lava themselves.

However, this is just the beginning, around Hathaway, more undead creatures appeared, in addition to skeleton warriors, there were also skeleton archers, skeleton knights and other high-level undead creatures, there were thousands.

Hathaway's expression suddenly became solemn, although the rank of these undead creatures was not too high, but their number was enough to kill an ordinary powerhouse, and no one could survive this siege.

Fortunately, Hathaway prepared a lot of magic scrolls and magic gems, which were pulled apart and crushed one by one, and colorful magical light shone around her, and rows of skeletons turned to ashes. If it weren't for the fact that there were too many of these undead, this battle would be a pretty good opportunity for Hathaway.

"Bright Holy Tower!"

Hathaway unleashed a guardian spell, and almost at the same time, four or five lichs suddenly appeared in the skeleton warrior's body, and dozens of pale fireballs annihilated Hathaway like a raging storm.

"There are lichs!"

Hathaway was taken aback, and immediately performed a killer move.

"Roar~"

With an earth-shattering roar, a huge figure suddenly appeared out of thin air, and the already impatient Blue roared and pounced on the skeleton warriors, and a breath of dragon breath sprayed towards the few unprepared lichs.

Click! Click......

The body shape of the dark blue is already quite impressive, and when the body pounces, more than ten skeleton warriors have been crushed, and the tail is swept, and the bodies of seven or eight skeleton warriors have been swept to pieces.

Those lichs who were releasing magic to attack Hathaway did not expect Hathaway to summon an abyssal evil dragon to come out, and suddenly, the three-headed lich was sprayed by the dragon's breath because he couldn't dodge, and his body immediately began to melt and disappear like winter snow encountering boiling water.

The appearance of the blue has undoubtedly improved Hathaway's situation, and with its strong body, Hathaway can attack with confidence as if it has an extra meat shield.

"Yuanyang Collapse Fist!"

"Nine Shadows!"

"Liuhe Slash!"

"Thunder Slash!"

"Cut the clouds!"

"Cloak Slash!"

"Liangyi Slash!"

"Split Light Slash!"

A burst of sword light shot around her, and the whole battle entered the current rhythm, which can be regarded as a real sharpening of Hathaway, and when her fighting spirit and yuan power were exhausted, she continued to cast spells. With the replenishment of the Rainbow Spring in the Fairy Garden, restoring magic is a matter of seconds......

Outside the castle, Bruno. Will and the others were as anxious as ants on a hot pot, and when dark clouds and lightning appeared above the castle, they knew that something must have happened in the castle, but the terrible curse and Hathaway's stern orders made it impossible for them to cross the thunder pool for half a step, but fortunately Hathaway obeyed the lie and communicated with them every once in a while, otherwise the group would have rushed in. Rao is like this, the roar of the undead inside, the roar of the dragon, and the sound of the sword qi breaking through the air still make the people outside tremble, and the days are like years.

It took a full eighteen spells before the sound inside gradually subsided, and the dark clouds dispersed, and although there was still a light chill in the castle, there was finally no such terrifying aura.

In the castle, Hathaway gasped and stood in front of the mage tower with Youlan in mind, the broken bones around him were slowly disappearing, and the ground destroyed by magic and swordsmanship was also recovering, feeling like a dream.

"What's going on? Is it a fantasy? Hathaway asked, surprised.

"No, this is the Hell Realm of the Eye of the Netherworld." Avril replied.

"Hades?"

Hathaway felt that the name seemed a little evil, and she subconsciously raised her head to look at the sky...... The purple sun had just risen, and the sunlight was pouring into the castle, adding some warmth to it.

"This is the special realm of the Eye of the Netherworld, capable of transforming the war dead into undead, and in its realm, these undead creatures will be restored even if they die again." Avril explained.

"Isn't that too evil?" Hathaway was a little resistant.

"There is no absolute good or evil in power, the key is how to use it." Avril Lavigne's answer made Hathaway roll her eyes, she had been educated by this non-human.

"Will they come out then?" Hathaway asked as she regained her magic.

"Theoretically, not for the time being, every time these undead creatures are destroyed, they will have to go through a period of recovery." Avril replied.

"So, if I fuse the Eye of the Nether, I can also use these undead?" Hathaway asked.

"Of course, as long as you're not afraid of being regarded as an evil heretic by the Church of Nature." Avril seems to be familiar with the current religious structure of the Titan world.

Hathaway snorted, ignored her, her eyes fell on the door of the mage tower again, and after a slight groan, she stepped forward, raised her hands, and with a slight stroke of her right fingernail on her right index finger, a stream of blood shot out and splashed on the tower door.

Rumble~

The mage tower shook violently, and the blood submerged into the tower, and then the tower door flashed a red light and slowly opened.

As the door of the tower opened, the cold aura became more and more intense, and Hathaway cast a Yuan Force shield in front of him, and stepped into the mage tower.

On the first floor of the mage tower, it is arranged like a hall, on the ground, there is a huge magic array, and in the center of the magic array, there is a black spherical crystal the size of a human head placed there, and the cold breath is emitted from there. (To be continued......)
