[Book 2] That time I got reincarnated as a slime,no, a DRAGON?

Ch-96

Rimuru's POV

"What?"

"You are protected by the God of Creation. If I sense correctly, you are from the Cardinal World. Since that works belonged to Azura Mazda, it makes sense you have his blessing. But why do you have a parasitic soul?"

"Parasitic soul?!"

"Ah! No need to worry. It didn't seem to be harmful to you. Atleast not yet. But a parasitic soul is so rare that even I have only ever seen two people have it in my entire life."

"What? What is a parasitic soul?"

"It's exactly what it's name suggests. It is a seperate soul that is like a parasite. It lives inside your soul. Of course, it is no seperate living entity. It is more like an Armor or a weapon. It can be used as a secondary soul to protect your main soul in case of attacks that directly attack the soul."

"Isn't that a good thing? Why is it called a parasite then?"

"Hmph. There is no such thing as free food in this world. The parasitic soul slowly eats on the soul of the host. At first it does nothing much, but as time passes, you start losing your memories, your feelings, your emotions, your experiences..... You start to lose sight of yourself.

A parasitic soul is a way to your doom. Only this who have willingness to give up everything, even their own soul use a parasitic soul to gain extra layer of protection for their soul and fulfill their aim."

"... Then can I remove it?" I ask. If it really is as dangerous as he is saying then I need to remove it. I have no need to lose my life. Atleast not again. But, to my question, Nihilanthian replied with a solemn expression.

"No. I cannot. It is too deeply rooted in you. I am surprised the parasitic soul hasn't taken over your soul already. It is as if the parasitic soul is in a dormant state. And you know what is the most surprising thing? Your soul isn't even injured. It is as if the parasitic soul has done nothing to you."

Hearing what he said, I tried to sense my soul. Even after looking over my soul, I couldn't find anything foreign. Everything seemed fine. Then what is he taking about?

"Why can't I see it?" I ask. Hearing my question, Nihilanthian shudders a little.

"... You can't see it? It's right in the middle of your soul." I once again check but find nothing.

"I can't see it...." What is happening? Is he messing with me? But why would he?

"Wait. You can use Nihilium a little, right? Try using it to analyse your soul."

Hmm? What would that do? Even though I had my doubts, I did what he said. I poured since nihilium into my eyes and looked at my soul, yet again. But this time, what I saw was completely different. Instead of the grey soul that I saw, I could only see random spots where nihilium was concentrated. Apart from the nihilium, I could also see another thing. A black red orb, sitting right in the centre of my soul.

As soon as I cut the nihilium supply to my eye, my soul returned back to being grey.

"Did you see it?"
"Yes. But why? Why couldn't I see it without Nihilium?"

"I am not sure either. But seeing how it isn't attacking your soul, it might not be a parasitic soul, but rather something similar."

"Something similar?"

"Yes. Something similar. Do you have any soul armor? Maybe it is a part of the soul armor."

"Soul armor? No. I don't have one. But I do have a soul weapon."

"Show it to me."

I did as he said and summoned my sword, Despair. Seeing the sword, his eyes widened. He quickly took the sword and started inspecting it as if he was trying to confirm something.

"Pass your mana through it." He told me, while not lifting his eyes from my sword. I did as he said and passed my magicules through it. Despair started shining with a black aura. After observing it for a few more seconds, he returned the sword back to me.

"Where did you get this sword?"
"Hmm... It is not from this world. I found it in my previous world."

"Where? Were there any graves nearby? Was there any signs of life nearby?"

"Umm... I don't really remember. It was completely barren. Rather, I am sure this sword was underground."

"Underground?"

"Yes. Well, the world which I belong to was quite technologically advanced. When we bombarded one of the planets, we unearthed this sword. Nobody was ever able to pull it out, until I came. I tried it as a joke, but...."

"It came out, huh? If that's the case, then it just acknowledged you."

"Well, I definitely know that swords such as Despair are rare and have their own will. But there is something special about this, isn't it?" I ask.

"That's right. This is one of the series that was created to kill us, the First Era Gods. It was a rare specimen of science, magic and craftsmanship. It has enough power to injure us seriously, and in the hands of the right person, it can even kill us."

"Then,... Isn't this quite powerful?"

"Well duh. In return for is strength, not just anyone can wield it. Only those that the weapon acknowledges can wield it."

"And I am one of them?"

"Yes. You do not have any idea how terrifying this weapon is. You are not even using it as a weapon till now. Till now, it was like using a sword as nothing more than a metal rod. There are lots of secret hidden inside that sword of yours. The power inside it is one of the strongest I had ever seen. Despair might not have the high power like Grief but it is highly adaptable and unpredictable. Combined with the fact that it can be used both defensively and offensively makes it a perfect for to your fighting style."

"... How do you know about my fighting style?"

"Don't worry about it. Just that one Slash that I saw you made me understand what type of swordsmanship you have. With Despair with you, I can confidently say that the parasitic soul is a part of the Despair. So it shouldn't hurt you."

"I see. So what should I do now?"

"30 days. I will give you 30 days. In these 30 days, I want you to improve your control over Nihilium and create a living being from it. Let me remind you. The creature that you create will be mindless. No matter how much you try to inject idea of self-consciousness into it. It might act, speak and look self-conscious, but it won't be. It will just be a puppet following your orders."

"Yeah.  I understand. What happens after that?"

"Hmph. Confident, aren't you? Well, I will give you my inheritance of you manage to do it. And you need not worry, no time will pass outside."

"Oh. That's really handy. Well then, let's begin, shall we?"
