Mainly thanks to Arcnotech Device called Light Absorber, which absorbed Holy Power or energy-based attacks made from Holy Power for a short amount of time before it would break.
Thanks to that Device, tens of millions of devils could survive ambushed made by Pure Angels easily. Even in battle right now, many devils could make quick attacks and kill angels solely on Light Absorber Device.
While in the same Class, usually devils were superior in terms of destructive power, the elemental advantage of Pure Angels and Fallen Angels made it so that most direct fights Devil vs. Pure Angel ended up in devil being often killed if not careful.
But that was instantly changed with the invention of the Light Absorber Device, which allowed the devil just to absorb the attack of Pure Angel, as he attacked Angel and killed him easily.
"I thought that you would be harder to kill... Archangel Uriel."
I said as I saw the bloodied figure of the Archangel Uriel, as several of his wings we broken or just burned by the enormous heat released by Bararaq Saiqa.
"Let's dance."
I said as I started throwing spells at injured Archangel Uriel one after another, not leaving him an opportunity to retaliate.

Devil Army clashed with Armies of Fallen Angels at the other side of the battlefield, which were led by the strongest Cadre of the Grigori, Kokabiel.
Devil Army was slowly advancing further, with most eye-catching, being Legions of Berserkers under command of Hela that were clad in the finest armors, with finest runes and inscription and armed with best runic weapons that could be mass-produced in the Draconic Deus.
Hela was on speartip slaughtering Eight-Winged Ultimate-Class Fallen Angels with her Necroswords like they were cabbage, leaving only dread and fear after she was done with someone.
"Ragnar, take command of the Vanguard and push forward. I am going to try to kill that pest, my beloved told me."
Commanded Hela with a cold bloodthirsty voice as she looked at Kokabiel, as several Generals that commanded either Aesir or Devils bowed deeply to the madwoman, be it in respect or fear as she departed to fight Kokabiel.
Hela was famous in the Underworld as someone who did whatever she wanted and kill whomever she wanted. The only person she listened was her lover, Lord Zeoticus Lucifer.
As Hela commanded, General Ragner, who now reached early stages of the power comparable to Satan-Class, took command of the Vanguard, numbering around half a billion soldiers as they drove deeper into lines of Fallen Angels.
While Hela conjured several Necroswords and threw them at Kokabiel, who was flying in the air, issuing one command after another, as he sensed incoming danger and barely dodged the Necroswords. Still, one of two of his wings were severed in the sneak attack.
He quickly patched up as he coughed some blood and looked at Hela with shock and fear. She didn't give him any more time to recover, as she instantly rushed at him with two Necrswords in her hands that shone in malicious black power, as she was using Power of Death to enhance her attack, as she ferociously attacked Kokabiel.
Fortunately for him, Hela still had the physique of Intermediate Stage God and didn't manage to advance her physical body to the Great God Stage, too, as that would require too much time and resources.
Kokabiel was physically as strong as Hela and was even a bit faster even with his injury, as his flight was now rather clumsy.
"Stop where you are, you fucking pigeon."
Screamed Hela as she threw after his several Necroswords along with blasts of Power of Death as she used her enormous reserves of Divine Power and Magical Power to conjure large-scale attacks of Power of Death or to cast Forbidden-Tier Spells that her lover taught her.
Fortunately for Kokabiel, or unfortunately for Hela and other Fallen Angels, she missed as Kokabiel used his subordinates as meat shields in front of Hela's terrifying attacks that annihilated entire Legions of Fallen Angels in seconds.
Millions died like that.
Kokabiel barely managed to dodge those attacks and was injured by aftershocks of explosions or other side effects.
Hela knew that she lost when she saw him reaching for the teleportation artifact, she knew about it from Zeoticus, but when she wanted to do something, Kokabiel already teleported out, leaving there only enraged Hela, who to vent her anger started slaughtering nearby Fallen Angels, by tens of thousands each minute.
Meanwhile one could see from distance, that a large part of the Fallen Angels army, around 40% that were talons of the army started quietly retreating, not sending alert to their compatriots fighting on the front, as their commanding officer Cadre Baraqiel ordered retreat as Azazel decided that it was enough.
Strangely only when an army of Devils surrounded Kokabiel's forces and factions of his opposition, led by Berseker Aesir, General Rangar, who just now smashed the skull of some Cadre-Class Fallen Angel apart.
While Azazel seemed like a good, cheerful, and friendly guy, he was still the most cunning, scheming, and despicable Fallen Angel.
With this move, he practically decimated his opposition, and while Kokabiel survived as he escaped, his forces were gone, he still had one or two Legions somewhere, but that was only a tiny part of what it was. He won't be able to make any major moves for upcoming centuries, and even if he tried something then, he would be no enemy for him.
