During past days, I have been preparing for the upcoming confrontation with Satanael's Army of Fallen Angels. My work was going through the major cities and upgrading the protection spells, securing teleportation arrays, and many other things, that could be done only by a very skilled magician such as me.

Now entire Gremory Territory has entered war mode, and Martial Law came into force. All cities are under the protection of Wards and Barriers, nonstop, due to possible sneak attacks or ambushes. Small villages were all evacuated and cities were enlarged, to accommodate the growing population.

Magical Towers have set their output on maximum, and are scanning their surroundings every half an hour.

Grayfia has been handling the administrative works for the past few days and has been working non-stop without a pause. Thanks to her, we were able to evacuate all civilians from small villages that can't be protected from strategic reasons to bigger cities. She personally oversaw construction works on the cities and accommodation of around 30 million devils, Aesir and Vanir.

I need to buy her something nice for her work, as I am very grateful for her help.

On the other side, Venelana has quickly converted all of the factories and manufactures to produce military supplies, weapons, and armors, as they were the most desired commodity in the Underworld right now.

And right now, I was leading 10 million Arcane Mechanical Automatons, Hydralisks to the battle. Together with me were three Ultimate-Class Generals and Isla who was sleeping beside me, as I was sitting in the command center of the enormous Emperor-Class Battleship.

I also took with me half of my Voidfleet. 75 Lunar-Class Cruisers, 20 Avenger-Class Grand Cruisers, and 2 Destroyer-Class Battle Cruisers.

Soon enough, my Fleet has arrived at the place, where Hela decided it would be best to clash with Satanael's Army.

This area, had a lot of Arcanotech Towers that were built by me, as it was the border of the Demilitarized Zone. After my Fleet has landed down, Drones started running here and there, placing down 500 Anti-Matter Magicule Canon Batteries that would start firing at the incoming army.

After all, Hydralisks embarged out the entire Fleet has entered stealth mode and hidden from sight. They would be the second wave of the long-ranged attack on the incoming Satanael's Army.

Drones were working fast and soon enough everything was ready, now the only thing that remained was to wait for Satanael to come.

I cast concealment spells on myself and Isla, only leaving three Generals not hidden, so Satanael would see them as an easy target and would choose to attack the Mechanical Legion. Most Fallen Angels were even more true to their sins than Devils.

The reason was simple, while Devils had some sin they had dominance, Fallen Angels fell due to something and became Fallen Angels. Usually, these traits were even stronger in Fallen Angels than in devils.

And truth to be told, most Fallen were plainly stupid or didn't care about anything at all. Rather a similar trait to the Devils.

And exactly after two hours, the sky went black as millions of Fallen Angels clouded the sky. I stayed hidden in the as I watched the leading Fallen Angel approach. He was a tall man dressed in the usual fallen angel battlesuit as others, described as having brown hair, silver eyes, and masculine facial features.

"Wait when they are in the right distance."

I ordered.

"All Anti-Matter Magicule Canon Batteries start firing."

One must admit that seeing five hundred Anti-Matter Magicule Canon Batteries firing at the same time, looked magnificent. As they shot, with each explosion that occurred high there, hundreds of Fallen were killed, and more were injured.

"Voidfleet Fire!"

And now the second salvo, from the Voidfleet. Voidships had more firepower compared to the Anti-Matter Magicule Canon Batteries, as even the weakest model of the Voidship has firepower comparable to the Ultimate-Class. Not to mention stronger models, that had the firepower of Satan-Class, and Emperor-Class Battleship had the firepower of Super-Devil Class.

It was really wonderful spectacle. Just one shot from the main canon of the Emperor-Class Battleship has killed more than ten thousand Fallen Angels alone.

"Keep firing till they are in the distance. Then stop artillery and let Mechanical Legion engage them in close combat."

I ordered as I spread my wings and flew high in the air while casting the Ultra-Order Spell Dimensional Judgement, which had the destructiveness that of Super Devil already due to its special nature.

As the artillery was firing be it from the Anti-Matter Magicule Canon Batteries or Voidships, tens of thousands of Fallen Angels have been killed in a matter of minutes.

I released Ultra-Order Spell Dimensional Judgement which tore through space and alone killed thousands of Fallen Angels alone. Ultra-Order Tier magic was really terrifying, and I cannot wait how the Forbidden-Tier would be.

After quick you detection spells after I saw Fallen starting engaging the Mechanical Legion, around 4 million Fallen Angels were killed due to intense firepower of the Anti-Matter Magicule Canon Batteries and Voidships. This was an enormously high number being killed just with Arcanotech Artillery alone.

"Lucifeeeeer!!!"

I heard an anguished scream of the Satanael, who spread his ten pairs of wings and flew directly at me in absolute rage. He was plainly stupid rushing at the master magician like that; really some Fallen had probably shit instead of brain.

"Isla do your job."

I whispered as I petted my Wampus Cat over her head, as she lunged at the nearest Eight-Winged Ultimate-Class Fallen Angel and tore away his arm in one swift move. Then she used her hypnosis magic and bewitched other Eight-Winged Ultimate-Class Fallen Angel to attack his comrades, creating absolute chaos on the battlefield.

"Hello, pigeon."

I said, as I crated a protective barrier around me with Protego Spell, which was basically an instant barrier spell for all Tiers. Satanael's attack just scratched my shield, as I summoned my scythe Rosenkreutz and cast several Dark Light Spears that started bombarding Satanael with thunderous speed.
