I woke up in the Graveyard, where the damp floor greeted me as I helped myself up, and felt two heavy things on my back, tied to it as if they were magically attached limbs. I touched them, and felt a weird sword sheath.

"What are those things?" I said as I unsheathed the swords, and I realized what they were. "No way... you guys are exactly how I imagine you guys to look like..."

In my right hand, I held a thin sword that emitted a power that could almost consume light itself. In my left hand, a bright sword that emitted spirit energy beamed as their master noticed them for the first time.

"The Shadow Sword...and the Spirit Sword." I said in shock. Those two were no joke, they're the real deal. Two swords from the Ten Swords of Power, on equal rarity with Reinhard's Dragon Sword Reid, and Cecilus Segmunt's Fiend Sword Murasame and Dream Sword Masayume.

"Yup! Those two were weapons of my former contractors, so I assumed ownership of those swords after they died, making them my property. Master showed an aptitude for using those, so the swords chose you as their next wielder!" Bayanga popped out from next to me as a sleepy Cahya floated after her as she yawned.

"Ya, unlike me, who was faithful, Bayanga was hasty for a new master so she went off contracting people before her powers ran out... pff, a punishment befitting the disloyal..." Cahya smirked as Bayanga stomped her feet in the air in frustration.

"Hey! Who're you calling disloyal?" Bayanga yelled in anger as she floated over to Cahya to punch her, and the two spirits, just like yin and yang, began fighting again.

"Sigh... they still don't learn..." Alchemis said as he appeared next to me, and I yelped in surprise. Instead of the usual blue orb, Alchemis was a tiny devil who wore a mad scientist outfit that's the same colour as his blue flames.

"You obtained a corporeal form? How?" I asked.

"You don't sound so happy." Alchemis stayed, and I waved my hands in obvious denial. "Well, I don't really know either. But maybe it's because I finally came out of the Witch Factor of Deceit, and it just eventually manisfested."

I was going to ask another question, but a pink haired elf suddenly appeared at the entrance of the graveyard, staring at me with a straight expression as I looked tilted my head in confusion.

Before I could say anything, another two dozen of the same girl popped up, and I realized who they were. "Ryuzu Meyer's clones. Why are you guys gathered here?"

"Because there's a new Apostle of Greed, of course." The one that spoke stepped forward, and I recognized her as Ryuzu Bilma, one of the original four clones tasked with overseeing the Sanctuary. "We came here to greet you, Echidna's chosen, Y/N-bo."

"Ey? What do you mean, I'm the new Apostle of Greed?" I asked in surprise. I knew what it was, since Subaru has also filled that position for a short while as well. However, the clones never acted this way towards him, neither did they towards Garfiel, another temporary Apostle of Greed. It was said that the Apostle can control the Ryuzu clones, so why am I one?

"It's because you have the necklace, Y/N-bo. Echidna-san told us that in the future, if anyone appears with the necklace, we should be the ones to listen." Ryuzu Arma, another clone of the main four, emerged from the crowd as she led the others to kneel as I waved in panic.

"N-no need to kneel! I'm just a guy who has a few spirits and two weird swords... wait, did you say necklace?" I said as I took out the pendant from the tea party, pitch black as if it was made out of obsidian.

"Yes, Y/N-bo." Ryuzu Delma, another clone came up as she held the hand of another clone, who I recognized as the half-disabled Ryuzu Shima. "The fact that you can receive that black pendant, and the two swords on your back, is proof of the witch's approval. Now, we await your order."

"Um..." I looked to Alchemis for support, but he was shrugging at me as he went to mediate the dispute between Cahya and Bayanga, leaving me helpless for the time being. "You know what, everyone except four the main four and Shima, please stay here because I have special instructions. I'll relay them to the black cloaks at a later time. The black cloaks can go rest, and as for the white cloaks, please come with me."

The clones nodded, and just as I finished my task, I had a new plan in mind. However, before I could get to strategizing, a voice popped into my head, none other than the Witch of Greed.

Ara, did you have a fun time with that surprise?

Now you decide to show up. Couldn't you come earlier and help me a little? I puffed my cheeks in anger, and Echidna chuckled.

Well, I couldn't afford to miss enjoying this show, could I? Echidna laughed as I glared at her mentally.

Well, time to start the training with my new amassed 'army' of Ryuzu clones.

Timeskippu*

The thing I went with first, was physical exercise. No, I do not mean I want Ryuzu clones with giant muscles, but speedy ninja like girls that seem like shinobi who can leapt through trees easily. So, I created an obstacle course with wood and diamond, along with boron and aluminum, part of the new arsenal I obtained after entering Echidna's graveyard.

The process gave me a huge boost, which broke the barrier of unlocking elements. Now whenever a new element reaches level one mastery, 4 new elements unlock. This also meant that I didn't really need to use every single element, which is nice considering that I do use some more than most.

Among the new four, aluminum was the most practical. Aluminum is a malleable metal that can easily be bent into any shape, allowing slopes and different shapes for the Ryuzu clones to go through. Sodium can be used to set off some bombs in the water, and magnesium is for the same purpose. Silicon is great for making wafers, which means that when the time comes to implement future technology, it'll be very useful. However, for now, it just acts as crafting material.

While the clones did their thing, I turned to Echidna for help.

Hey, Echidna, can you teach me Al Shario? That spell seems insanely cool... you know, the one that you wiped out a bunch of wolves with?

Eh? Al Shario? That spell... NO WAY!

Huh? Why not? It isn't some secret technique that you can't pass down, right?

No... it's just that you have way to less mana inside you to ever cast that spell... so that's why I can't.

Oh... I see... HUH? I don't have enough mana? How much mana do you need to cast a freaking meteor spell then? I can even cast Absolute Zero with Alchemis' help, so why not? Unless... it really is in a different realm.

Y/N, instead of trying new things, shouldn't you start improving your current techniques? Your Goa series seems to be fine for now, but you should develop your yang and yin magic more, including the lightning magic series you created yourself. I'm aware that you cannot use that time freezing spell for too long, so let's start working on the others first.

Ah, I knew it was the right decision to contract with you. You sound like a very, very experienced game guide, you know? Well, I guess I'll get to it, then.

Game guide? Hold up, what do you mean?

Timeskippu*

After an hour of training, I was exhausted as I sat down on the floor after ordering the Ryuzu clones to do whatever they were supposed to do. They were fast learners, having their physical abilities drastically increased. I guess this is a good thing for now, but I haven't made any progress yet.

Perhaps I could be of assistance? Echidna suddenly said in my mind as I smiled.

Definitely, Chid-chan! Please teach me how to strengthen my spells... or whatever I was supposed to do...?

You're taking this the wrong way, Y/N. Think of what you want to achieve for every different spell. Let's take Akra, the strengthening spell for example. It's a yang magic spell that drains mana quickly, meaning that you can't use it for very long. So, what is the best way to use it in the little time you have?

Use it in one burst to achieve insane speeds? I guess that could work if my mana does not go up for now... by the way, how do you increase mana?

I don't know either... there might be a mana cap for people who use their own mana, but for spirit users like yourself, all you need to do is to let the atmosphere's mana flow into you. Imagine it, and let the magic do its work.

I tried Echidna's advice, and called Cahya out to support me. I gathered mana around as I detected them, the little white specks floating around in the space next to me. Now, to absorb them to use it for my spell. I felt the mana flow into me, and when it reached its brim, I unleashed it.

"Ul Akra!" I burst forward almost at the speed of sound, charging forward so fast that if it wasn't for the protective mana skin that forms, I would've felt the blood rush to the back of my head. I punched through as I landed, around 300 meters away from where I started.

To do that in just 1 second... is that power comparable to the Bowel Hunter's now?

The more amazing fact was that I still had mana left over. Quite a lot, actually. I think I could use around 7 more at max before having to recharge again.

That's great, Y/N! You're making progress. Another thing is your authority. Now, as I already have seen, you currently possesses two authorities: Deceit and Sloth. I don't know how Deceit works, since that is Frakine-chan's area of expertise, but I can do something about sloth, or even any other see, the sins hold power themselves. Why do think I was able to amass so much knowledge even after this? It was because I truly had desire for it. So when you use sloth, loosen your body. Don't try to move or exert yourself. Relax. Let the extensions to the work for you.

Okay then. I said as I unleashed the Imperceptible Extensions again, and the cold feeling purged my back as I saw the two hands emerge from my back, awaiting my order.

"Tear that tree apart." I said as I crushed my hands together in the direction of the tree, using as little effort as possible. This time, instead of their usual power, which was the same as mine, the hands bursted forward with speed as they charged the trunk, and crushed it to shreds as I gasped at the amount of power.

Surprised? You still have a lot to learn, Y/N. This world might seem familiar to you, but there are many hidden knowledge that even the author does not know. That's where I come in.

I know. That's also why I'm seriously glad that I formed a contract with you.

So I guess we both have something to learn, hm?

Ya... I guess. Thanks, Echidna, for helping me.

Of course. Now, is it my time to be indulged in knowledge?

Sure, coming right in.

With that said, I jumped into the Castle of Dreams as I muttered the six-lined keyword, leaving the material world behind as I entered the graveyard of souls, and faced my contractor as we began our fifth conversation.

Authority(ies):

Authority of Deceit (Commonly known as Authority of Elements):

-Vacuum Trigger: An innate ability stored within the tesseract-shaped Deceit Witch Factor, allowing the user to spring themselves from unconsciousness when the mana fluctuations around them changes drastically, as a built-in self-defence mechanism of the body.

-Critical Overload: A mysterious ability that protects the user of the Deceit Witch Factor, causing them to unlock their true potential while their actions are coordinated by ?, helping them avoid certain death. This ability only triggers when the user is about to die and has a 15 minute cooldown.

- Haywire Warp: A variation of Critical Overload that allows the user to warp the attack that will kill them, creating a tear in space-time to absorb the attack. Meanwhile, the abilities of the elements are unleashed and they will defy the chemical laws before the user decides to cancel their existence.

-Decagenso Rupture: A variation of Critical Overload that allows the user to combine ten elements into one attack, fusing them into a substance unable to be defined by chemical laws. Then, the substance explodes from the inside to spread parts of itself into the opponent's body, replacing their atoms with the substance itself.

-Pure Truth: Y/N's knowledge of the future. Although he claims that he can only know up to a certain amount, it is only a cover-up to avoid suspicion. This ability also allows him to lie without being detected (e.g. Crusch's divine protection), as long as it is part of his knowledge of this world's future.

-Veritas Oneiro Chunyu: The 'Truth Dream Injection'. A sub-ability of Pure Truth that allows the user to show others fragments of Pure Truth to get a better understanding of a situation or past. This ability cannot show the future.

-'Suitoru': A magic spell that allows the user to absorb a certain ? of the enemy, making it their own and can be stored for later usage.

-Partial Authority Immunity: Y/N is fully immune to some authorities, while some still have a diminished effect on him.

-Scindo: The ability to split the Deceit Witch Factor into pieces to implant them in others, but the pieces can only be taken back a year later. Current Percentages: Y/N L/N: 99.997%, Crusch Karsten: 0.003%

Authority of Sloth:

-Imperceptible Extensions: Y/N's authority also somehow manifested almost the same way as Betelgeuse's did. When activated, two invisible hands can be summoned to be moved around telekinetically. Penalty: If a person is not considered as Y/N's enemy, they will see the extensions. However, another holder of Sloth will also see the hands, regardless of the previous statement.
