Dark area.

The sound of killing in the cave gradually subsided, and the town under the mage tower was covered with corpses, paving from outside the city gate to the passage in four directions, and blood stained the mushrooms in the field red.

The souls of more than two thousand slaves were absorbed. Even though Rennes consumed a lot, they gradually rose to more than two thousand three hundred units.

At this time, Renne's mirror time came and turned into a bubble and disappeared.

The mirror of Resling lasted for three minutes longer, opening a series of free doors to allow his teammates to enter and reach the top hall of the Mage Tower.

It was not until this moment that they saw the true body of the Eye Demon Elder.

Barack turned around the Eye Demon's corpse, his face full of disgust, and he pinched his nose and said, "This thing looks so disgusting!"

Izt smiled and said, "The Eye Demon Elder is already better than the average Eye Demon. It has a layer of horny armor, which does not reveal greasy skin like the ordinary Eye Demon. It has a mouth full of venom, and the smell is not that smelly."

"Well……"

Barack was a few steps away, "But its strength is very strong, and it actually controls so many slaves. If I were the only one facing it and besieged by the slave army, I would probably have to escape."

"No matter how strong he is, he is easily killed by Rennes." Dawnsous exclaimed.

Asina looked at Reslin, her eyes full of concern.

She knew that Rennes had returned to Glamorgan, and the soul contract sensed that Rennes had just undergone a soul transformation, and was promoted to the legendary level, and his strength increased a lot.

Leslin nodded slightly at the female giant, saying that she would relieve her.

"What's the matter now?" asked Barack, "What are we going to do next?"

"Of course it's to control this mage tower."

Resling replied, walking to the console in the middle of the hall, reaching out to hold the crystal bead on it, injecting a trace of mana.

Suddenly, the control bead was activated and a stream of information was transmitted into the mind.

This information includes a large amount of content about the Mage Tower, including a tall tower log, written in the high elf text.

Resling took a quick look.

Sure enough, the creator of the Mage Tower was not an Eye Demon, but a Drown Mage called "Kevisasson" started to build more than 600 years ago. Kevisasson is a level 19 mage. He was stuck in a bottleneck for hundreds of years, but he couldn't even master the first Nine-ring spell, and there was no progress at all.

To be promoted to a great mage requires building three Nine-ring spell models, not even mastering one, let alone three.

This made Kvi Sasson very desperate for a while.

Later, he unexpectedly obtained an ancient book from the Third Era, which originated from the ruins of an elf city in the New World. It records a method that can build a spell model with the help of the mage tower, which not only improves efficiency, but also increases some success rate.

So Kvisason looked for the place to build the tower in the upper floor of the dark area, and finally chose this cave.

Building a mage tower is not easy, it requires countless resources and manpower.

The dark area has poor resources and endless struggles. Kevi Sassen fought alone again. He broadened the cave and took more than 60 years to collect enough resources to build the main structure of the Mage Tower bit by bit, and then spent another thirty years laying out rune magic arrays in the tower.

Kvisason named this wizard tower "Obsidae".

The scale of the Obsidian Tower is half shorter than that of the normal mage tower, only more than 130 meters high, and the internal space is only one-third of the normal mage tower.

Even so, it took Kvi Sassen more than 30 years to complete the magic array of the Mage Tower.

The biggest problem is the lack of alchemy materials.

Many materials are very scarce in dark areas, and even none are there. Kwissan had to go to the surface to collect them, or go to the human kingdom of the Old Continent to disguise himself as a purchase.

After nearly a hundred years of hard work, the rune array of Obsida Tower has only been completed about half.

Kvisason's tower log came to an abrupt end here.

The last message about him was to go out to collect a batch of important magical alloys, without saying where to go, and in short, he never came back.

Leslin couldn't help but sigh when he saw this.

The lines of the high tower log reveal Kwissan's desire to be promoted to a great wizard. This wizard is a lonely explorer on the path of magic. He acts without moral bottom line and is cruel in his way. He is merciless to both his enemies and his tribe members. He treats the slaves he controls as tools, without any kindness.

His actions only have one goal, that is, to be promoted to a great master.

But he failed.

Resling speculated that when Kvisason went out that time, he had an accident and was most likely dead. Otherwise, he would never have given up on the Obsida Tower, which he had devoted a hundred years of hard work.

After Kvisason disappeared, Obsida Tower was silent for more than 340 years.

Until decades ago, an ordinary eye demon broke into the cave and discovered the unfinished mage tower and took it for himself.

This Eye Demon uses the Obsida Tower to be promoted to the legend and becomes the Eye Demon Elder.

Then, like Kvisason, it enslaved underground creatures through the Mage Tower, built a large army of slaves, occupied territory, expanded its power, and allowed the slaves to collect resources and continue to improve the tower. However, the magic knowledge of the Eye Demon Elder was far inferior to that of the previous master, and his strength was several levels different. After decades of struggle, he only completed a very small number of rune magic arrays, and made little progress.

The Eye Demon left a large number of records in the Tower log, hundreds of times more than K Visason's content.

The majority of the division is that it praises itself and praises itself.

Leslin was speechless when he saw it, and deeply realized the narcissism of the Eye Demon, and jumped over and stopped looking.

In addition to the information of the two tower owners, the log also contains the magic array effects that the Obsidian Tower has been arranged, its protective barrier, the magic that can be cast, the functions of each floor of the tower, etc. As well, as long as you use the high elf runes to leave a spiritual mark in this crystal bead, you can become the new owner of the Obsidian Tower.

Resling was excited.

A mage tower is right in front of you, and there is no spellcaster in the world that will not be moved.

Even if Renn already has a mage tower, he would not think there are too many mage towers. What's more, the Obsidian Tower is specially built to assist in building the Nine-ring spell model. I don't know how effective it is yet, so it's worth a try!

Kvi Sasson never seemed to have thought that he would lose the Obsidian Tower. He left a rune magic array to assist in the promotion in the crystal bead.

This huge and complex rune magic array is very ancient at first glance, and comes from a high elves.

Reslin judged it based on his feelings only, and the magic circle is effective!

Kvisason was only half completed and had to be combined with the entire mage tower to activate. The remaining half of the alchemy materials needed were worth about four million gold shields.

This is an astronomical wealth for others, and many alchemy materials cannot be bought even if they have money.

But for Resling, it's just a little bit.

Ren said one sentence and could collect all the materials in less than two months, and arrange the rune array without help. Leslin himself could do it. He used mirroring once an hour, and twelve mirrors to work together, and his work efficiency increased several times. He could also use real mirroring once every seven days, and his efficiency was improved again.

Resling predicts that he should be able to complete the construction within half a year!

It is definitely worth it to use four million golden shields and half a year to improve the Obsidian Tower as long as it can speed up the efficiency of constructing three Nine-ring spells by yourself.

"Risling, is there any problem?"

Seeing that Resling was pressing his hand on the crystal bead and many people didn't say anything, Bellak couldn't help but ask a question.

"fine."

Leslin let go of his hand and briefly told his teammates about the origin of the mage tower, but did not disclose the rune array that assisted in the construction of the Nine-ring spell.

"Master Kvisason!" Izt exclaimed.

"Do you know him?" Leslin asked.

"Yes." Izt nodded slightly and said, "Master Kvisason, like me, was born in the city of Mosobrey, which is the largest city of the dark elves. He was once one of the most famous legendary mages of Mosobrey. He was highly capable and had extremely profound magic knowledge, no less than that of a great mage, but he disappeared hundreds of years ago and turned out to go to the upper level to build the mage tower."

The dark elf showed a little regret in his eyes, "The Obsidian Tower has been abandoned for so many years, which shows that Master Kvi Sasson has failed and has even died."

The teammates think so too.

The caster will never give up his mage tower, either because he lost his freedom or his life.

Resling said directly: "I want to control this mage tower."

Before his teammates responded, he proposed a method to allocate spoils, "The value of the mage tower is extremely high. If I control it, I will no longer participate in the distribution of other spoils. There is a batch of treasures in the middle warehouse of the Obsidian Tower, all of which are gold, alchemy materials and weapons and equipment collected by the Eye Demon through slaves. I am useful for alchemy materials. I convert it into an equivalent gold shield to distribute them equally to you. I don't want all magic equipment."

Izt, Bellack and Dawnsos looked at each other and vaguely guessed that Resling might have concealed some information.

But there is no more suitable person to master the Mage Tower except Resling.

Only the caster can control the mage tower, and they can only stare at it. Moreover, the main forces who broke through the mage tower this time were Rennes and Resling. They just killed the slave army. They could do it with the mirror image of Rennes and Resling, and there was no need for help at all.

Even if Reslin had occupied the Mage Tower without permission, they had nothing to say.

"Can."

Izt agreed immediately.

Barack and Dawnssus followed suit, and Asina would not have any objection.

Leslin didn't say much, and immediately pressed his hand on the crystal bead, condensed it into a line of high-level elves runes with his magic power, chanting spells in his mouth, and the bead immediately reacted and emitted a burst of strange magical light.

The entire Obsidian Tower trembled gently, and the rune magic array inside and outside the tower body flowed energy.

It lasted for half a minute.

When the tremor of the tower stopped, Resling had become its new owner.

He formed a connection with the crystal bead and knew the situation of the entire mage tower. When he was in the tower, he could mobilize the energy of the tower to cast spells and control it in all aspects with just one thought.

This crystal bead is not only the control core of Obsidian Tower, but also a superb magical item.

Through it, the tower owner can release the Nine-ring mind control technique to control the mind of the target being suppressed in the tower, making it his own slave. Of course, using the mind control technique to consume a large amount of energy from the tower, and the target's level must be lower than himself, and the number is not unlimited.

The stronger the Lord of Obsidian Tower is, the more slaves he can control.

Elder Eye Demon enslaved more than a dozen legendary early-level slaves and dozens of high-level extraordinary people with the help of the Mage Tower. Through these powerful slaves, it controlled more slaves and expanded its territory outward.
