Stretching her body, Shiro looked at Nan Tian who stood opposite her.

Since they were resting for the day, Shiro decided to spar with Nan Tian for a bit since he had just recovered from his injuries.

As for the zones that she had captured, she distributed tasks to everyone to keep them busy. Plus, they're also helping with the defences of the zones so it was killing two birds with one stone.

"What's Misu up to? I haven't seen her today." Nan Tian asked as he created a few weapons of light and twirled them around.

"Misu? I had her organise her own group within the city. Since we're now in an alliance, it's good for her to build some influence in the city. I'm not sure about what kind of group she wants to make though since Silvia is already in charge of the healers. While she used to be healer, she is now a necromancer." Shiro shrugged her shoulders.

"I'm not sure she'll want to teach necromancy since it could be abused. Even if it was unlikely with the people in this city, you never know." Nan Tian said as Shiro nodded her head.

"True. I'll see what she's planning later anyways. I also need her to create an anchor here so that I can increase the power produced within this city. With more anchors, I'll be able to prepare better defences. That way, even if someone does discover this city and launch an attack, they'll be destroyed with ease."

"I'm sure that's already the case considering what we have for defences." Nan Tian chuckled.

Shrugging her shoulders, Shiro summoned a sword.

"Ready?"

"Of course. Start whenever you want."

The spar was simple, nothing intense. It was merely something to help them move around a little before the real test.

Since they were taking a day off, Shiro wanted to finally achieve the power of pausing time.

She has done it in a chamber, all that's left is to achieve it in combat.

"Helion's still making some adjustments for my sword so it'll take a while. But for now, I'll try to carve my own runes in this." Shiro smiled as she adjusted her grip.

Suddenly, golden runes flared against the blade edge.

Dashing forward, she inserted mana into the blade and tried to complete the spell in an instant.

Several tier 8 magic circles appeared on the surface as Shiro swung towards Nan Tian.

Trying to complete the calculations, she couldn't help but flinch when she felt the mana start going berserk.

Before her blade could even reach Nan Tian, it shattered apart as due to the failed spell.

Quickly taking a few steps back, she created a second sword to parry Nan Tian's counter strike.

"Well that went just swell didn't it?" Shiro forced a smile.

"Mn, perhaps you should try it without moving around first. It's already hard enough for you to do it in a large open space compared to a sealed room much less while you move."

Thinking about it for a moment, Shiro sighed, and agreed. This was something that even Chronos had a little trouble with considering the mana consumption so it was only natural that she wasn't going to achieve it in an instant.

If she was being honest, it was a miracle that she even achieved it for her chamber.

Creating another sword, she etched the runes along the surface once more. Closing her eyes, her mana flared as tier 8 magic circles appeared once more.

Now that she wasn't moving around, it was a little easier but it was still hard to keep things contained.

Furrowing her brows, sweat dripped down her face. One by one, the tier 8 magic circles sparked to life as they were completed.

'Right, one more and I sho-' Before she could even finish her thought, her sword transformed into a bomb from the mana that was gathered inside and threatened to explode.

Quickly throwing it in the air, she created a barrier around the two of them.

*BOOM!!!

Watching her sword explode and shake the entire training hall, Shiro identified the problem.

For the chamber, the power was spread evenly across a large sealed room so it wasn't 'difficult' to activate.

However, this time, she's trying to use something as small as a sword to delay time in a large open space.

Even with her nanobots, which are Demi god level, it was still difficult to contain the power required to pause time.

"Unless I reach tier 8, it'll be hard to create a sword that'll be s-"

Pausing for a moment, Shiro looked up at Nan Tian.

"Is something wrong?" Nan Tian asked but Shiro shook her head.

"Nope. Nothing is wrong, in fact, things couldn't be better." She grinned.

"You see, the problem I have now is I don't have a good 'container' for this power and I don't want to use my body as one since it'll definitely harm me. But as I am right now, my nanobots cannot contain this power in the form of a small sword. However, I have the best 'container' for this power." Shiro laughed.

"My indestructible rainbow grade sword that's under Helion's care right now. Since it's indestructible, I can load it with as much energy as I want without worrying that it'll blow up in my face. So even if Helion doesn't upgrade it, I should be able to cast the spell using that blade." She explained as they made their way towards Helion's office.

"Would you be able to handle the calculations then? We don't know what will happen if we have unstable energy within an indestructible container. If you fail at casting the spell, things will most likely go south. The moment a channel opens between you and the sword, that energy might lash out at you." Nan Tian asked as Shiro thought about it for a moment.

"I do have a few precautions regarding that but if it is like what you said, I can just open a channel outwards. Then it becomes an empowered attack no?" Shiro grinned as Nan Tian sighed.

"Hais, even though you're taking steps to avoid harming your body, you're still putting yourself in danger by trying things that should be impossible."

"Well… no pain no gain. I didn't get to where I am today without any risks after all." Shiro chuckled as Nan Tian had to admit that she was right. Without any risks, she wouldn't have achieved some of the feats they know her for.

Arriving outside of Helion's Office, Shiro knocked on the door and noticed that there was a barrier in place that sealed everything inside the room.

Raising an eyebrow, she couldn't help but wonder what he was doing inside for him to require something like this.

Just before she could even knock, the walls surrounding the office started to bulge.

"???????"

Both Shiro and Nan Tian looked at the now swelling walls in confusion.

"What the-"

*BOOM!!!!!

Before she could even curse, the wall exploded as Helion's figure flew past them, slamming against the walls.

Shattering the windows, he quickly jumped back on his feet.

"Alright you little sh*t. Just because you're a rainbow grade item doesn't mean you can rebel like this." He snapped. Storming back into the office, flames and mana continue to explode from the gap in the wall.

"The f*ck was that?" Shiro couldn't help but ask, seeing the hole in the tower.

"Seems like he's having some trouble with the sword?" Nan Tian raised an eyebrow.

Quickly fixing the walls, Shiro glanced into the office and saw Helion surround himself with golden flames and a giant hammer.

She watched as he started 'combat' with the sword on the table. Each swing of his hammer would cause sparks to fly in the sky.

Seeing the golden runes slowly being etched into the blade, Shiro couldn't help but raise an eyebrow.

However, just as he finished one rune, the force launched him outside of the barrier once more.

"F*ck!"

"Are you ok?" Shiro asked as Helion glanced up.

"Ah I didn't see you there. Sorry I'm just having a bit of trouble with the last few parts. It was fine earlier but it's getting harder now. I'll be honest, I don't think I can carve all the runes you wanted me to. Just two and it's already launched me away twice." Helion sighed.

"Upgrading a rainbow relic truly isn't easy. I think you can just take it now. I don't have the strength or capability to etch more on for now. Every rune I add on only increases its resistance."

Hearing this, Shiro waved her hand and summoned the sword to her side.

Seeing the description, she couldn't help but widen her eyes.

[Silvanis – Executioner Blade of the Goddess – Rainbow]

Upgrade in progress (3%)

Seeing the line beneath the title, Shiro didn't expect that he would actually upgrade it. When she wanted him to carve some runes it was just so that she could cast spells easier. But there's now a chance that Silvanis could become something stronger than just rainbow grade.

Blinking her eyes in surprise, she watched as Helion extinguished the flames before falling asleep on the sofa.
