Kind of forgot about this. lol
Anyway, this is what the novel says: "All angels, attack! Hurry!" Every one of the Archangel Flames shot toward Ainz like bullets. "What a lively lot… Albedo, step back." Nigun could hear the cool, calm voice of someone who was being attacked by angels, but did not care. Ainz was surrounded by so many angels that nobody could even see him, but yet his voice did not carry even the slightest hint of worry. It looked like he would be impaled by countless blades — no, Ainz's spell took effect before that. "[Negative Burst]."' 'The air shuddered. A wave of black radiance erupted from Ainz, like the negative image of a camera flash. It only lasted for an instant, but it had an immediate and obvious effect. "Im-impossible…" Someone muttered those words, carried by the wind. They could not believe what was happening before their eyes. The angels, over 40 of them, had been annihilated by the black wave. Their opponent had not used dispel magic to neutralize the summons. The angels that were blown away by the black wave had taken damage. In other words, Ainz had used a powerful spell to wipe out all the angels in one fell swoop.'' Nigun could not help but tremble. He recalled the words of the Kingdom's strongest warrior, Gazef Stronoff. "...Hmph, you fool. In that village… is a man who is stronger than me. His power is unfathomable, but he could take you all out by himself… Trying to kill… the villagers he protects… is impossible for you." The scene before him proved the truth of those words. Nigun erased those words from his mind, trying desperately to bring himself over. Nigun knew that the members of the strongest special ops group, the Black Scripture, could also eliminate this many angels. In other words, all he had to do was treat Ainz as an opponent on their level. While he might be as strong as a member of the Black Scripture, he had the advantage of numbers on his side, so victory was still possible. However, could those members of the Black Scripture take care of all these angels with just one spell? Nigun shook his head to clear away his doubts. He could not think of that question. If he got his answer, then he would truly be done for. Therefore Nigun reached inside his coat, and touched the item within to give himself courage. He fervently believed that as long as he held it, everything would be fine. However, his subordinates did not have the same source of moral support that he did. "U-uwaaaah!" "What, what the hell!" "It's a monster!" Once they realized their angels were useless, they wailed and fell back upon the spells that they knew and trusted. "[Charm Person], [Iron Hammer of Righteousness], [Hold], [Fire Rain], [Emerald Sarcophagus], [Holy Ray], [Shockwave], [Confusion], [Charge of Stalagmite], [Open Wounds], [Poison], [Fear], [Word of Curse], [Blindness]..." All kinds of spells rained down on Ainz. Yet, even as the storm of magic lashed against him, Ainz was unmoved. "Well, all of these are familiar spells...who taught them to you? The Slaine Theocracy? Someone else? There are more and more things I want to ask you now." Not only could he slaughter all their summoned angels in one move, their spells were also incapable of harming him. Nigun felt like he was trapped in a nightmare. "Hyaaaaah—!" One of the men screamed wildly as he saw that his spells were ineffective. In desperation, he pulled out a sling and loaded it with a bullet. Although Nigun doubted the effectiveness of such a projectile when even an angel's sword was useless, he did not stop the man. The bullet that could easily shatter bone sped toward Ainz. It was followed by a sound. That sound was like an explosion. An instant. It had happened in an instant. Since they were in battle, they could not take their eyes off their target. However, Albedo — who should have been behind — had moved in a mysterious way in front of Ainz to defend him. The source of the apparent explosion was because she had violently kicked off the ground to get to where she was. With a speed that the eye could not even see, Albedo swung her bardiche, tracing a beautiful curve of the weapon's sickly green light in the air. After that, the man with the sling slowly collapsed to the ground. "...Huh?" Nobody knew what had happened. They were the ones who had launched the attack, yet the result was completely opposite — one of them had fallen instead. One of the men went over to inspect his dead comrade, and he shouted: "His, his head's been smashed in!" "...What? Smashed… don't tell me it's the sling bullet he threw!" Why had he been killed by his own projectile?" It doesn't say anything about her getting close to him again, so she was probably still out of the range of the Negative Burst.
