There are a total of 200 World-Class Items, but that refers to 200 different types, not 200 individual pieces.
World-Class Item [Caloric Stone].
It is a consumable World-Class Item that allows the user to submit requests or proposals to the game operators.
It can also be used as material for crafting items, weapons, or NPCs.
In addition, it can be embedded into equipment such as swords or armor, or used as the power core for a golem.
The [Caloric Stone] can be considered a counterpart to the [Ring of Ouroboros], though its actual power is far inferior.
The [Ring of Ouroboros] can force the developers to break the rules and grant special privileges, while the [Caloric Stone] can only submit requests that fall within the rules.
Although both are World-Class Items, the gap between them is quite large. However, the [Caloric Stone] has a very wide range of applications, an advantage the [Ring of Ouroboros] cannot match.
Furthermore, the [Caloric Stone] is not unique. As long as one knows the correct method, it can be obtained continuously.
That was exactly what Naohara had in mind. Sending the Quagoa to mine earlier had simply been a preparatory move.
"As expected. But Naohara, you should know that ordinary ore alone isn't enough to obtain Caloric Stones."
Momonga wasn't surprised by the answer. He had already suspected as much.
However, he didn't have much confidence in Naohara's plan.
Caloric Stones cannot be synthesized from ordinary ore. They require the precious Prismatic Ore.
In the game Yggdrasil, Prismatic Ore surpassed even Adamantite in both strength and rarity, and was regarded as an extremely valuable mineral.
In the past, The Great Tomb of Nazarick had accidentally synthesized a single Caloric Stone through a stroke of luck, which was later used up by Tabula Smaragdina.
Back then, The Great Tomb of Nazarick had attempted to synthesize a second Caloric Stone, but their efforts were discovered by a hostile guild.
The enemy guild even used one of the Twenty [Rings of Ouroboros] to forcibly seize Nazarick's mining area, leaving them unable to obtain another Caloric Stone ever again.
Seeing that Momonga lacked confidence, Naohara smiled slightly.
"Momonga, do you really think I would do something pointless?"
"Caloric Stones can indeed only be synthesized from Prismatic Ore, but that doesn't mean ordinary ore is useless."
"With the Super-Tier Magic [Wish Upon a Star], we can transform ordinary ore into Prismatic Ore."
Naohara explained.
Super-Tier Magic [Wish Upon a Star] might be rather useless in many situations, but converting ore was something it could definitely do.
Compared to creating something from nothing, conversion required fewer conditions and could produce a larger amount of Prismatic Ore.
That was the main reason Naohara had the Quagoa start mining in the first place.
However, even after hearing Naohara's explanation, Momonga still felt puzzled.
What Naohara said made sense, but even so, a single use of [Wish Upon a Star] could only convert a few thousand pieces of Prismatic Ore.
Yet synthesizing a [Caloric Stone] required tens of thousands, even hundreds of thousands, of additional ore.
Moreover, casting the Super-Tier Magic [Wish Upon a Star] required consuming experience equivalent to five levels.
Not to mention the cash item [Shooting Star Ring].
Even with the World-Class Item [Avarice and Generosity], which could store experience, obtaining five levels' worth of experience was extremely difficult in the New World because most people had relatively low levels.
Once spent, it was gone.
Unless they carried out a massive slaughter, there was no way to sustain such an enormous expenditure.
"This is giving me a headache. Stop beating around the bush, Naohara. Just tell me already."
Momonga's thoughts ran in circles, yet he still couldn't figure out how to deal with the experience cost of [Wish Upon a Star].
He looked at Naohara, who was leaning against the sofa, and let out a helpless sigh before asking directly.
"Momonga, the answer is actually far away and yet right in front of us."
"And I'm not planning to synthesize just one Caloric Stone. I'm planning to mass-produce them."
"The solution has been there all along. We simply never realized it."
Naohara slowly stood up and walked over to a crystal sphere.
Inside the sphere floated several strangely shaped items. Every single one of them was a World-Class Item.
Just like Naohara had done before, Herohero had also taken out all the World-Class Items he carried before undergoing fusion and handed them over to Momonga.
Muttering a short incantation, Naohara retrieved one of the items and placed it in front of Momonga.
"Well? As long as we combine this with [Avarice and Generosity], once Blackie wakes up, the three of us can cast the Super-Tier Magic [Wish Upon a Star] every day and continuously obtain Prismatic Ore."
A small door carved with demonic figures floated in midair. Momonga froze for a moment before immediately understanding.
[World-Class Item: Demon Gate]
"Activating this item continuously summons demons capable of flooding an entire world. Unless the holder stops the summoning, it will never cease."
"The summoned demons range from level 50 to level 90 and include every known species. All demons obey the summoner's commands."
"I see. I see! That could work. This might actually work!"
Momonga suddenly raised his head. The human disguise he had been using shattered instantly, revealing the terrifying undead magic caster beneath.
His passive ability [Despair Aura] activated uncontrollably, making it obvious how excited he was.
If not for the effect of the World-Class Item [Eternal Seal], his body would have already been glowing green.
"Naohara… I have to admit, you're a genius."
After quite some time, Momonga gradually calmed down. When he spoke again, his tone was complicated.
He had completely understood the plan.
[Demon Gate]
By using this World-Class Item to summon a large number of level 90 demons, the three of them could equip [Avarice and Generosity] and kill them, storing massive amounts of experience.
Then they could use that stored experience to cast the Super-Tier Magic [Wish Upon a Star], converting ordinary ore into Prismatic Ore without paying the experience cost themselves.
Although the three of them could only cast [Wish Upon a Star] twelve times per day in total, as long as they kept at it, mass-producing [Caloric Stone] would be entirely possible.
That was a World-Class Item.
The idea of mass-producing World-Class Items was something Momonga had never even dared to imagine.
"Don't rush, Momonga. Let's wait until Blackie wakes up before we start. We have plenty of time. Right now, the priority is dealing with the Argland Council State."
Naohara smiled as he looked at the impatient Momonga.
But in the next moment, a flash of green light appeared, forcing the smile off his face.
"My apologies. I got a little too excited."
Momonga suppressed the joy in his heart and canceled the effect of [Eternal Seal]. The green glow flashed once before his emotions finally settled.
Just as Naohara had said, they had plenty of time.
Everything could wait until Herohero woke up.
When that time came, they could share this joy together.
"Let's go. It's time to head to the Argland Council State!"
