Astaroth’s bats now out of the way, I turned my attention back to the main battalion. The mutants had gotten closer to the wall while we wasted time on these bats.

“Hey, Lilliana! I like that cosmic vibe you’re bringing with your star-themed spells. I can’t use light magic but allow me to continue the trend! Black Hole!”

A black sphere the size of a fist appeared above the enemy infantry. The mutants looked up and stared at it, puzzled.

The black hole activated and began to absorb the nearby matter. It started with the surrounding air, then the weapons of the mutants were drawn in. Finally, when the black hole got large enough, it devoured the mutants themselves.

After a moment, the crimson light in the sky became distorted. The light itself was getting swallowed by the black hole, offsetting Lilliana’s spell.

Next to me, Élise was holding on for dear life on the battlements. Her light build was getting pulled into the black hole.

I decided to retract my spell.

The dark sphere, now the size of my house, vanished alongside thousands of mutants.

Trembling, Élise slouched to the ground. She had faced death twice in rapid successions, so it could be considered understandable. Yet, fearing death was disgraceful for a member of the Crown’s Overseers.

**Black Hole worked well. It proves that dark magic is effective against mutants.**

“And now…! Meteor shower!”

This spell was a mix of Earth, Air, and Gravity magic. Dust particles in the high atmosphere would meld together with the help of some physical matter produced from mana. Gravity magic would accelerate the fall of the amalgam, and Air magic would then reduce the friction from the air, accelerating them even further until the edge of the wall of sound.

The size of the amalgams depended on the caster. In my case, I loved big ones.

However, the collision of a gigantic boulder at the speed of sound would certainly destroy the nearby city I was supposed to protect.

So, I was forced to use these miniature balls of dirt instead. It felt more like a rain of bullets rather than a meteor shower.

Nonetheless, the mutants under the area affected by the spell were obliterated. The series of quick, consecutive impacts left modest craters in their wake. Needless to say, the result was bloody. Limbs were torn, and guts spread on the soil.

Élise, who just got over her fear of death, looked over the battlements, only to find this scene of ruthless carnage. She covered her eyes and crouched down once more, trying to hide from the harsh reality of the battlefield.

**I can’t help but bully her.**

“Oh, come on, Élise. Only now are you deciding to act like a woman? Stop being a wuss and get out of there, or I’ll make sure my next attack is bloody enough to drench these walls in crimson red!

“No! I’ve seen enough war! I want peace… Peace and Love!”

“What the hell are you trying to do with your character? You’re just confusing everyone!”

She lacked any sense of femininity and considering her kill count over her very long life was probably higher than mine, she shouldn’t be scared of blood. But there’s no point trying to understand her, so let’s just forget what she just said.

Albert came to the rescue. He grabbed her shoulders and forced her to stand up. Yeah, Albert was there too, even though he didn’t do anything so far.

“Stand and face your fears, elf! It is the only way to overcome them!”

“Shut up! Unlike you morons, I have a delicate maiden’s heart that I must protect from all these bloodsheds!”

“Delicate? Don’t make me laugh! The only things that are delicate about you are your noodle arms!”

I left these two to argue and turned my focus back to the battlefield.

“Well, I guess I must bring her back to her senses with some gore and violence. Hail of blades!”

Air currents merged, densified, and molded into sharp edges before flying toward the monstrous mass at high velocity.

The mutants were apparently all made from the same mold. They had similar heights along with many other characteristics.

This made things surprisingly easy. By making my wind blades at neck level, and then making them fly horizontally, I could slice up multiple heads in one go.

As expected, blood spattered in every direction. Unfortunately, it did not drench the walls in crimson. In fact, the range fell short by only a few paces before the rampart.

On the other hand, the grassy plain was soaked in this cloggy liquid. It had converted this once-fertile land into a reddened swamp haunted by thousands of despairing souls.

Still, nothing a little bit of mana couldn’t fix.

I scanned the battlefield. My last spells cleared most of the battalions in the center, in front of the main gate, which meant it would probably be safe for now. I even saw their ram laid on the ground next to countless corpses.

What worried me was the ladders they were carrying along.

While I concentrated my efforts on the middle, the troops on each side kept advancing toward the rampart. After a quick estimation, I realized I wouldn’t be able to wipe out all of them before they reached the walls. I wouldn’t have enough time to destroy the ladders either since they were split among the different battalions.

In any case, we wouldn’t lose the city. The king would bring some infantry on the walls and repel the mutants climbing on the ladders. Meanwhile, I would finish the mutants beyond the rampart, and we could win this battle with minimum casualties.

That’s right, with the current scenario, I couldn’t avoid casualties.

In my opinion, even one or two deaths were unacceptable. With my overwhelming power, I wanted an overwhelming victory.

Earlier, I realized that these monsters were weak to Dark magic, which makes sense, considering that Dark mana is rare. The creatures in the dense mana zones only adapted to the common types of mana.

Therefore, I would use the largest and deadliest spell in my dark magic repertoire.
