Setting up a camp up in the nearby hills of the capital, Shiro looked at the city through her orbs and couldn't help but furrow her brows.

As if it was a zombie apocalypse, all of the residents in the city have been turned into these monstrosities that roamed the streets.

The once bustling city was now quiet as the only sound they could hear was the occasional grunting from the monsters.

Located in the centre of the city, was a nest of sorts as there were hundreds upon thousands of tunnel entrances that lead deep underground.

Unfortunately for them, it seemed like the boss was located deep underground.

"So, how should we approach this?" Shiro asked while glancing towards Kuromi.

"Hm… I'd say we want to clear out a portion of the city first or else we might be surrounded should the boss call for them when we're fighting.

"However, if we did that, it'll take us several days to weeks for us to actually kill most of the monsters in the city." Kuromi frowned.

"Stealth is risky as well since we don't know where to look in order to find the boss." Shiro sighed.

'No wonder the Empress wanted us to make allies. Going through all of this alone would be quite tough especially since I don't have access to most of my skills. If I could use my Nanomancer class, I would have just bombed the entire city to the ground.' She thought to herself.

Shaking her head, she got rid of the thoughts before taking a closer look at the city.

"Do you think it's possible for us to flush the boss out instead of going in?" She asked as she glanced at all the tunnels.

"Oh? That could work but the amount of energy needed for that would be ridiculous." Kuromi replied.

"Indeed, rather than flooding the entire tunnel system, I was thinking that maybe we should just remove the top. It's kinda like taking the roof off a house." Shiro smiled.

"Hmm… how do you plan on doing that?"

"Remember the spell that the dragon and giant used in that fight? I still have the composition of it in my mind. If we make some edits, we'll be able to get some of the shadow guards to help construct that spell so that we can destroy the roof of that base. The scale would be smaller but it should be enough for what I want to do." Shiro explained.

"Alright, let's do that. We're short on manpower anyways so this is probably the best choice. We drag the boss out and fight in our turf." Kuromi smiled as she brought out her notebook.

"So, how do you think we should go about modifying a one person spell into one that requires multiple people?" Shiro asked.

"The same way we use our energy now. Using gateways. Each person here would act as a gateway, funnelling energy into a 'main', who would then construct the spell." Kuromi replied while drafting up a few prototypes for this method.

"Oh? Who's going to be the main then?" Shiro asked.

"I am. You sit out for this one since we'll be needing your full power in the actual boss fight. If anything, can you draw down the magic circle in this notebook so that I can memorise it?" Kuromi replied.

Handing Shiro a spare notebook, Kuromi walked over to the shadow guards and explained the situation.

As Kuromi was explaining the situation, Shiro started to draw a magic circle.

Seeing that the complexity was more than what a single page could contain, Shiro ripped out a few pages and connected them together.

Once she finished the drawing, she laid it out on the ground.

"Right then, the main thing about this magic circle is these two sections. If you mess these two up, the spell will not activate. The section on the left is for directions while the one on the right is amplification. You'll need to also keep these two in mind, especially the amplification section." Shiro said as she pointed at each of the spots.

"I see… alright, I've pretty much got a rough understanding of it now. The only concern I have is whether or not our practice would attract any attention since the surge of energy might be quite obvious." Kuromi furrowed her brows.

"Don't worry about that, I'll protect you lot while you do this. I'll be using the spear and shield in their base form to fight off the enemy so I won't be using up my energy." Shiro smiled before bringing out the weapons.

Even without funnelling energy into them, they were still amazing weapons that were far above the average standard.

"Ok, just remember that you should avoid coming into contact with their blood if possible. We still don't know what's causing their infection. If things get a bit dangerous, don't hesitate to use the Celestial Armour." Kuromi warned as Shiro nodded her head.

During the days of travel towards the capital, they had somewhat got an understanding of what each of the weapons do.

The spear could be charged to produce one extremely powerful throw while the shield could save your life three times every three days. As for the armour, all she could find out right now was that it could massively bolster her defence and resistances. The more energy she funnels into them, the stronger it becomes.

With the jewel also in her possession, each spell would require less energy so she could fight without worrying too much if sh*t hit the fan.

Grabbing one of the spare outfits in the carriage, she changed into one that covered most of her body so that she could avoid direct contact with the fluid.

"Alright, I'll keep the battle a little further from this place so that the bloodshed wouldn't affect you all just in case the parasite is airborne." Shiro smiled as Kuromi nodded her head.

Making a few more preparations, Kuromi had every guard stand in a specific location.

"Right then, this should be correct. Is everyone ready?" Kuromi asked as the guards nodded their heads.

Smiling at their response, she stomped down as a faint tether could be seen, connecting the guards to each other.

As this was happening, the surge of Celestial Energy seemed to have attracted the monsters in the surroundings since they all looked towards them at the same time.

"That's rather creepy." Shiro joked as she watched the monsters come closer.

Once they were within 200 meters away from them, she leapt into a sprint and readied her spear.

Twisting her body, she threw the spear towards the closest monster, sinking the spear tip deep into its body.

Grabbing the pommel of the spear, Shiro pushed it down before stomping it with her foot.

Splitting the monster in half, she quickly raised up her shield and pushed the blood aside.

Glancing around her, she saw that there were two monsters trying to flank her from both sides.

Quickly ducking down, Shiro grabbed the spear and spun it in a circle around her, slicing the legs of the monsters and forced them to fall over.

Slamming her shield against the monster's head, she crushed it as if it was an empty can before backing off.

In a single exchange, she was able to kill two monsters and incapacitate the other. However, there were still plenty of them charging towards her. Thankfully, there weren't any monsters behind the guards so she only had to worry about one direction.

"I suppose this is good practice for when I go against people who cancel out mana." She mused to herself as she readied her spear once more.

Grinning with battle intent, she dashed towards the horde.

As she continued to kill the enemies, Kuromi's spell neared completion as the array could be seen floating above the capital. At this point, all of the monsters had been aggroed to their location as Shiro was fighting with everything she got so that they would not disrupt the spell.

During this, she was forced to use a few spells since she would not have caught the monsters that rushed past her otherwise. But with this, Kuromi was able to charge her spell without any problems.

After a few moments, the magic circle floating above the capital solidified as intense heat could be felt even from this far out.

Without a second word, Kuromi activated the spell as a blinding pillar of fire descended onto the capital.
