Chapter 90: King of Heroes

"Now, just sign here, and everything will be done," I said with a smile.

"Why does this feel like I'm signing my soul over to the devil..." Rudra muttered as he signed the non-aggression treaty.

"Oh, I wouldn't need permission to take your soul, but that's beside the point." I looked at the new arrival in the Land of Repose. "Rimuru, your turn now."

"So you kidnaped me and made me sign a non-aggression treaty with the strongest nation? I was dealing with the problem in Raja." Rimuru said with a tone of disbelief, annoyance, and gratitude for my help.

"Raja..." I muttered to myself. I think there was something about that place. I then had a look of realization, "Oh! Ultima, didn't you say they made a deal with you before we met?"

"Huh?" She thought about it for a while, "Oh yeah! I completely forgot about them. If I remember correctly, we started a game... But what was it about..."

"The queen is dying due to a cure on her tiara," Rimuru said.

"Oh yeah, that's it! She would get enough power to protect her country, but her future children would be cursed."

"Umm... Could you undo it?" Rimuru asked Ultima.

"Ehh... I don't know..." Ultima looked at me.

"Go with Rimuru and help them with it,"

"Before I go, I should give you a helping hand," I said and put my hand on Rudra's shoulder, 'Do it, Persephone.'

Without having any Ultimate Skills, he would need to rely on Velgrynd. A Unique Skill holder wouldn't stand a chance against an Ultimate Skill holder.

I could quickly evolve his skill, bypassing all the requirements.

[The Unique Skill: [Chosen One] has been upgraded into Ultimate Skill: [King of Heroes]...]

She said with a hint of excitement about something. She seemed too excited for me to upgrade his skill.

Rudra looked at me flatly, "Since when was gaining Ultimate Skills that easy..." He asked.

"I used some of my magicules to force your skill to evolve." I lied, "I can't have a weak ruler. It will lead to more troubles, and I won't be able to laze around."

"..." All of them looked at me, but I wasn't bothered.

"Now then, I will leave Seris and Testarossa in the Empire with you so they can help you deal with the problems while I'm off to deal with a world-destroying dragon that isn't actually a dragon," I said and sent them back to the Eastern Empire and Rimuru with Ultima back to Raja.

"Now then, let's go and deal with Ivarage," I said and teleported myself to where the Spooky Palace was located.

The place where Ivarage is sealed is called the Spooky Palace... And here I thought my naming sense was terrible.

Spooky Palace sounds more like a kid's attraction than a place where a powerful entity is sealed.

Let's see if I can devour it with the whole seal using [Akasha].

I put my hand towards it, and after saying the skill name, it activated, "Return to the Root, [Akasha]." [Akasha] shot out of my hand and started devouring the Spooky Palace at high speed.

...

..

.

Ten hours... Ten hours was what it took for my skill to devour it.

I wiped the sweat from my forehead. 'That should be enough work for one day, don't you think, Persephone?'

[Yes, master, you have done so much today, so you need to rest now...]

'Is that sarcasm I'm hearing, Persephone?'

[No master, it's just your imagination.]

'That line is getting old...'

[Just like you master.]

But before that, I made a last stop to Arise all the dead enemies, and now my army expanded by a couple of million.

With the big problem out of my way, I think it's time to return home and relax.

The only person left to deal with would be Yuuki.

Persephone POV:

When my master returned to his castle, I didn't waste any time and started working on a new skill that would fit perfectly with Ultima, who uses poison magic.

Using the information from the seal my master just absorbed with her [Lord of Deathly Poison: Samael] and what makes the monarch out of [Shadow Monarch: Ashborn] to make a new skill.

It wasn't easy for me to separate the monarch part from that skill, but I did it in one hour and started working on the new skill.

It was a success, and a new Ultimate Skill was created, the Ultimate Skill: [Plague Monarch: Querehsha]. The only thing left is to get my master's permission to give the skill to Ultima.

...

..

.

After dealing with the problems in Raja, Ultima returned and was mad that a demon of her lineage made everything even more complicated.

Getting an upgrade to her Ultimate Skill helped her get over it, but at the same time, she didn't like that it would get even easier to win her fights.

Sigh... Why can't she be like my master, be happy when she gets stronger, and not complain about it?

I also calculated that the skill would influence her race from currently being a Shadow Demon into a Monarch Demon in a couple of hundred years.

This, coupled with the fact that she is a Primordial Demon, will surely be interesting to watch.

I could also do the same thing with Testarossa and her [Belial] and upgrade to a Monarch Type. I should prepare everything if my master ever asks me to make it.

Ultimate Skill: [White Flame Monarch: Baran] was created and safely stored for future use.

But the most important skill my master gained today is the Ultimate Skill: [King of Heroes]. The skill, as my master would describe it, is an absolute cheat and plot armor.

Of course, now that I have it, I can easily counter it if Rudra ever tries to do anything to my master.
