Dumbledore placed a mask on his face.
"Ariana, de-activate stealth mode."
"Yes, sir."
On the border of the Empire's territories, thousands of light-years away, an entire city suddenly appeared outside the star system. Dumbledore saw a man waiting for him.
He had black robes, a long scythe, and red markings across his left eye. He had grey skin, and a small portion of his mouth was rotten to the point of showing the bones.
"Lord Guzznad, do you want to fight here or in the Mirror Dimension?" Dumbledore asked calmly.
"No problem," replied the Death God, who knew a Tier 9 battle could destroy the entire Milky Way Galaxy if their strength were not probably controlled.
Dumbledore secretly sighed in relief. It would be nigh impossible to force or trick the opponent into the Mirror Dimension–even if it was just a clone. And Guzznad refused to acquiesce. Dumbledore would have to report to the Empire, forcing them to activate the Grand Arcane Shield, which linked all the mana and leylines of all the star systems in the Empire's territory to enact a shield that covered countless star systems.
The problem with this shield was how much money and resources were needed to activate it. And given that Guzznad was a Tier 9 God, the shield itself would not be enough, and an Aether Core of the same level as the Floating City would be required to provide additional energy.
Luckily, there was no need for trouble.
A portal appeared between these two, and Dumbledore followed through with the Floating City. And as soon as he entered the Mirror Dimension, he did not waste time.
He accessed the mana from the Aether Core/Philosopher's Stone to boost his strength.
"Let's go, Fawkes."
An enormous phoenix flew from the city, spreading its dozens of kilometers long wings. Guzznad was not surprised by this True Phoenix as this was not the first time he confronted his opponent.
"Ariana, remove all the limits of the Floating City. Bombard our enemy with all the canons–except for the Void one."
After giving the order, Dumbledore began his own attack. He felt the slight burden of the mana overflowing through his body. He had previously controlled the Floating City when he was Tier 6. And now, it was easier to do at Tier 7; it placed less burden on his body and soul.
Dumbledore used countless elemental spells to destroy Guzznad. On top of that, the floating city bombarded him nonstop. However, the latter only evaded or defended, never going on the offensive.
Undead Legion
Guzznad waved his scythe, and millions of undead materialized before him. He then ordered them to rush toward the Floating City's shield in suicide attacks; they did the same to Fawkes.
Fawkes's flames and the Floating City's shield instantly killed and purified the undead. However, there was no end to the number of them; no matter how many were killed, Guzznad would make more.
Dumbledore rushed as he knew his opponent was buying time.
"Ariana, send the Golem Legions."
Then, an army made of all types of golems: soil golems, rock golems, golems, and metal golems. They rushed towards the army of undead to destroy them. Although the golems lost regarding numbers, they won in strength.
Additionally, Dumbledore was not finished. His attacks destroyed many planets, stars, and solar systems. So, he used Transfiguration Magic to transform the debris into more soldiers to block.
With Guzznad's legion occupied, Dumbledore acted more aggressively. He took out a potion to drink before using a spell he created himself:
Arcane Rune Spell: The Phoenix's Last Song.
Fawkes turned into a phoenix the size of a galaxy before rushing to Guzznad to burn him into ashes. The latter erected a barrier made of black flames to protect itself.
Back in HQ:
Olivier watched the battle with a frown. She could tell Guzznad's clone won't last long, but the issue was how long was too long. She checked the monitor that displayed the situation in Omegon System.
She had mobilized a space fleet armored with Tier 9 Canons to annihilate the entire solar system. However, despite the constant bombardment, the protective shield of Omegon remained intact.
'Guzznad is way more powerful Tier 9 God that we gave him credit for.'
Tier 9 Galaxy level had a wide gap. A person who could destroy one galaxy with one attack is Tier 9, but so is a person who could destroy 1,000,000 galaxies with one attack. And the universe had trillions of galaxies.
'Should I use the Void Canon?'
That was the only solution to deal with the Death Shield on Omegon. However, she and the others have long decided not to use the Void Canon in this war.
The main reason for that is news leaks. Because of the Universe Web, a lot of information that the Empire wanted to keep a secret has already leaked, meaning the Tier 10 Gods in the Central Region has already noticed their existence.
If it were not for Guzznad blocking the entire Milky Way Galaxy somehow, the situation would have been worse.
Olivier decided not to be hasty. It has not reached the point where the Void Canon is needed. She looked at the screen where Rowena faced another clone of Guzznad.
Her situation was similar to Dumbledore's, as the enemy simply wanted to buy time. She looked at her opponent and sneered.
"Raven, prepare to enter Dimension-AlphaV."
"Yes, master," replied the Artificial Spirit.
"Oliver, activate the Grand Arcane Shield, even for a moment."
"Alright," she replied despite not knowing Rowena's plans. As for the massive loss of money, it can be recuperated.
Rowena controlled the Floating City to open a space-time channel out of the mirror dimension and fly out. Guzznad followed–despite the possibility this may be a trap.
However, he did not have a choice since he did not want the Floating City to reach the Omegon Star System. And after learning that from his main body, the Empire activated their Grand Arcane Shield, he knew this was the correct choice.
So, he used his Death Authority to mess with the space-time channel and prevent teleportation.
'Gotcha,' thought Rowena. She used the space-time disturbance created by Guzznad's intervening to teleport the two of them to Dimension AlphaV. When it comes to manipulating space-time, Rowena was confident that only Edward was above her.
And when it comes to certain aspects, even he could not compare to her.
Guzznad soon found himself in a dark gray place. He looked around, wondering what the opponent's plan was. But before seeing the surroundings properly, he began dissipating as if he had never existed.
"Where is this?" he asked Rowena floating above the Floating City, underneath the Void Shield. Of course, she did not respond. Dimension AlphaV was an empty and owner dimension the Empire discovered.
And she used it for her experiment by modifying it and filling it with Void Energy. The Floating City can survive here, but not Guzznad.
After Guzznad completely dissipated, Rowena suddenly did not feel good as the veins on her neck began to spread. So, she teleported to the Intensive Care Unit.
Before falling asleep, she ordered.
"Raven, enter Auto-Pilot Mode. Your mission is to go to Omegon and conduct an Exterminatus Order."
"Yes, master."
Raven controlled the Floating City to teleport to Omegon and immediately began to bombard the shield. After a few attacks, cracks appeared on the shield, but it would slowly heal.
It would take the city a few minutes to break it. Luckily, Dumbledore's Floating City appeared to aid. It took a few minutes to break the shield with the other present.
Then, Omegon Star System was annihilated with one shot, not leaving a single piece of matter or energy from the entire star system. Afterward, the Floating City purified the death energy remaining from the process of the undead building a base.
