After more than ten hours, Rennes explored the entire mage tower with Nomiya.
During this exploration process, Nomiya completely believed Rennes' words.
After all, this long-unmaintained giant mage tower couldn't be fake.
If Kael'thas was still alive, this mage tower would definitely not be in this state and they would definitely not be able to freely walk around inside the mage tower.
Rennes didn't pay attention to Nomiya's thoughts, because his attention was now focused on the silver door in front of him.
This door leads to the underground level of the giant mage tower.
He expected that behind the door should be the core power room of this floating city, the location of the Mithril Core.
After all, Rennes had already searched every other part of the floating city.
But found no trace of the core power room.
No need to say more, after confirming that he couldn't use spatial manipulation to directly pass through this door.
Rennes immediately raised the Sun God Sword in his hand and slashed towards the silver door, preparing to forcefully break in.
However, the defensive magic set up by the Great Arch mage Kael'thas in the core power room of the floating city was extremely powerful.
The radiant sword energy condensed by Rennes fell onto the door was instantly extinguished, without causing any ripples.
Seeing that force wouldn't work, Rennes immediately changed his mindset.
"I declare, anything that hinders my progress shall disappear."
The Mythical Talent: Law command was activated.
In the next second, a powerful and marvelous force appeared out of thin air.
It began to act on the silver gate in front of him.
At the same time, the power of the laws within Rennes' divine fire was also rapidly depleting.
After five minutes, due to insufficient energy supply, coupled with the lack of maintenance for tens of thousands of years, the powerful defensive magic attached to the silver gate ultimately failed to stop Rennes' Law command talent.
Under this force that modified reality, it directly dissipated.
And at this moment, the power of the laws within Rennes' divine fire was left with less than three hundred strands.
"I am still too weak."
Realizing this, Rennes also became aware of his own "weakness."
Perhaps there was no one on the Roland Continent who could be his opponent, he considered himself invincible.
But in the vast universe beyond the Roland Continent, he was far from being considered a strong individual.
Not to mention, the defensive magic left behind by the Great Arch mage Kael'thas tens of thousands of years ago almost rendered him helpless.
Such a huge gap, instantly made him lose all his arrogance and self-satisfaction of being invincible in the world.
However, Rennes did not underestimate himself.
He believed that he would eventually catch up to and even surpass Kael'thas. After all, he is a man with a golden finger.
No further time wasted. After dispelling the guarding magic, Rennes immediately pushed open the silver door.
Following the steps of the corridor, he walked down. Nomiya followed closely behind.
After about a minute of walking, Rennes and Nomiya arrived in a room full of energy pipelines.
And in the center of this room, there was a huge semicircular metal pedestal.
The pedestal was fixed with a large purple crystal with a diameter of twenty meters.
Obviously, this purple crystal is the legendary Mithril Core that possesses infinite energy.
One of the highest magical achievements of the Netherreth Empire.
However, this Mithril Core was obviously in a damaged state.
The surface of the crystal was covered with dense cracks, it looked like it could completely collapse at any time.
"Huh!"
Seeing this, Rennes couldn't help but sigh.
Although he was mentally prepared before, but seeing that the Mithril Core of this floating city was completely useless, he was still somewhat disappointed.
Because it meant that he needed to obtain a new Mithril Core himself in order to restart this floating city.
And he had no idea how to make a Mithril Core at all.
"It seems that I can only buy it from the family store."
Rennes thought to himself, the family store even sells complete Time Divine position.
Naturally, it is impossible for there to be no Mithril Core.
However, the price may be a bit expensive.
Rennes took a look, there are a total of five different models of Mithril Energy Cores sold in the family store: micro, small, medium, large, and extra-large.
Although all five models of Mithril Energy Cores have unlimited energy, their output power varies greatly. The larger the model, the higher the output power.
And this floating city of Kael'thas obviously requires an extra-large Mithril Energy Core to operate perfectly.
This highest-level Mithril Energy Core is extremely expensive.
It requires the equivalent of system points accumulated over twenty million years of cultivation to purchase.
"Forget it! Forget it!"
Seeing this price, Rennes instantly gave up the idea of buying.
This is too damn expensive, even if he sold all his belongings, he might not be able to afford it.
There's no way, Rennes can only choose the next best option.
Although the medium to large Mithril Energy Core may not have enough power to perfectly operate this floating city, it should still be able to unleash some of its power.
Checking the prices of the large and medium Mithril Energy Cores.
Large Mithril Energy Core, price: seven million.
Medium Mithril Energy Core, price: one million.
Still can't afford the large Mithril Energy Core, but the medium-sized one...
With some effort, it might work.
After all, he still has a divine Power Crystal worth over seven hundred thousand system currency.
"Exchanging these divine Power Crystals for a usable super floating city."
"It's definitely a huge profit."
Thinking of this, Rennes immediately made up his mind.
However, before he could collect the divine power crystal in his hand, Rennes seemed to think of something.
He walked towards the damaged super large-scale dense energy core.
He was prepared to retrieve it for the family store.
Although this thing was already useless, but no matter what, it was a top-notch item with a selling price of up to 20 million.
Even if it was sold as scrap, it would still be of considerable value.
Before retrieving it, Rennes specifically observed this damaged dense mithril energy core.
There were no traces of external damage on it. Instead, it seemed more like the output energy power was too great, causing it to overload and break.
"Perhaps when Kael'thas performed the divine ascension spell, he used this super large-scale dense energy core as the energy source to drive the spell."
Rennes silently speculated in his heart.
If not for this, he really couldn't figure out how Kael'thas could make this energy output powerfully huge dense energy core overload and break.
However, his speculation obviously could no longer be proven.
The truth of the matter had been completely buried in the river of history with Kael'thas' death.
Without dwelling on this matter any further, Rennes directly retrieved this broken super large-scale dense energy core for the family store.
In the next second, fifty-three thousand seven hundred system points appeared in his account.
"F#ck!"
Rennes exclaimed in his heart.
Although he already anticipated that this thing was valuable, but he never expected it to be valuable to this extent.
A completely scrapped waste can be sold for over five hundred thousand system points, this is equivalent to over five hundred thousand years of cultivation!
Sure enough!
Top-quality goods are top-quality goods no matter how damaged they are.
"I saved over five hundred divine power crystals with this move."
Coming back to his senses, Rennes was very happy in his heart.
Then, he recycled over four hundred and seventy divine power crystals.
After accumulating one million system points.
Without hesitation, he bought a medium-sized Mithril energy core from the system mall.
In the next second, a purple crystal about five meters high appeared in front of Rennes.
It was surging with substantial magical energy.
"A medium-sized energy core?"
Nomiya beside him was also stunned. A trace of shock couldn't help but appear in her eyes.
You should know that, only arcane masters powerful enough to rival gods can create dense energy cores of medium size or higher grades.
This thing is also a precious treasure in the most prosperous era of arcane masters, the Netherreth era.
She had always wanted to get one but couldn't, but who would have thought that Rennes would actually have an intact medium-sized energy core in his hand.
"Don't just stand there, come and help."
Seeing Nomiya standing still, Rennes couldn't help but shout.
Although he had an energy core, the base for fixing the super large energy core obviously couldn't match it.
Therefore, before embedding the dense energy core, the base must be modified.
"Oh, ok!"
Upon hearing this, Nomiya instinctively responded while walking towards Rennes.
The two of them then worked together.
It took more than ten days.
Finally, they successfully modified the pedestal of the core power chamber, then they placed the medium-sized energy core on it.
"Buzz! Buzz! Buzz!"
With the continuous output of energy from the magical core.
All the surrounding energy pipelines immediately lit up.
Obviously, the energy system of the floating city has been successfully restored.
However, to restart the entire floating city.
This is not enough, because the energy circuit central hub of the floating city is still in a damaged state.
Without the allocation of the energy circuit central hub, no matter how much energy the magical core produces, it cannot be accurately delivered to every corner of the floating city.
There is no other way, Rennes can only continue to work with Nomiya.
Fortunately, compared to the core power chamber.
Repairing the energy circuit central hub is relatively simple, it just requires more materials and time.
It requires a large amount of mithril, a rare magical metal with strong magical conductivity.
After more than a month, the mithril reserves in Rennes space ring were exhausted.
He also purchased more than a hundred tons by recycling over a hundred divine power crystals from the family's shopping mall.
Finally, Rennes and Nomiya completely repaired the energy circuit central hub.
Under the diversion of the central energy circuit, endless magical energy was being transported to every corner of the floating city.
Countless magic arrays are re-activated once again.
Under the effect of the giant cleansing magic array, the once heavily dust-covered floating city instantly becomes refreshed.
Next, Rennes began the final step of resurrecting and taking control of this super floating city.
Arriving at the central control room of the floating city, Rennes reconnected the core control console to the energy network for activation.
Then sets himself as the highest authority controller, and Nomiya as the secondary authority owner.
Due to the complete destruction of the tower control room, the original owner, Kael'thas, is also gone.
This floating city has become, in fact, ownerless.
Therefore, this process went very smoothly.
In less than an hour, Rennes succeeded.
"Floating city, take off!"
After obtaining the highest authority. Rennes, with an excited and anticipatory mood, gave instructions to the console.
"Charging the anti-gravity ring, it is estimated to be ready for takeoff in ten minutes..."
Ten minutes later, this massive floating city suddenly shook.
Then it started to rise bit by bit, gradually leaving the ground.
As time passed, the ascent speed of the floating city also became faster and faster.
It only stopped when it reached an altitude of tens of thousands of meters.
Above the pristine white clouds, a majestic and massive island city is freely soaring.
That scene, looks extremely awe-inspiring.
