How come the Ace of Cups isn't considered the Holy Grail?

Yuuto, who was halfway down the stairs, suddenly turned back and said to Rin Tohsaka, who was standing there in a daze.

"Remember to also prepare some of your blood and hair; this is very important!"

"Huh? Wait—"

Rin Tohsaka wanted to call out to Yuuto and get an explanation, but when she turned around, she only saw the tightly closed basement door.

After mentally ranting about Yuuto's riddle-like behavior, Rin Tohsaka turned around and went to find the blueprints for the Jewel Sword as he had instructed.

No matter how precious it is, it's just a design blueprint. Although she doesn't know where Youdu found out about its existence, she can't make it even if she has the blueprint, so it doesn't matter if she gives it to Youdu.

If the other party really does create a gem sword, or something of the same level, using alchemy and blueprints, it would be far more valuable than just a few blueprints!

Of course, she would make a copy as a backup before sending it over.

This can be achieved through both magic and technology, but she's not very good at technology, so she'll stick to magic!

But how can alchemy even use blueprints as materials?

It’s really amazing…

From this moment on, Rin Tohsaka's understanding of alchemy, under Yuuto's influence, began to veer towards a strange direction.

Neither the party that was affected nor the party that was affected discovered this matter, or even if they did discover it, it probably wouldn't have had any impact.

After all, this is what they consider alchemy to be.

Chapter Nineteen: Baoyu's First Appearance

"Hmm... let me see..."

In the basement, Rin Tohsaka had already taken down the materials that Yuuto needed. She even gritted her teeth and drew a vial of her own blood and hair, and cut off a section of hair from each of her twin tails and placed it on the table.

After she left, Yu Du's gaze swept past the ace gem and fell upon the other materials.

【Gemstone Pendant: A】

【AZOTH Sword: A-】

[Design drawing of the Jewel Sword: A-]

[Blood of the Five Elementalists: B-]

[Hair of the Five Elementalists: C]

[Gemstones imbued with magical power: B+ to C]

[These are gems that store several years' or even more than ten years' worth of magical energy in Rin Tohsaka. However, because these gems are all somewhat flawed in terms of quality or the amount of magical energy they store—for example, top-quality gems don't have much magical energy, and gems that store a lot of magical energy are of low quality—they have not become Rin Tohsaka's trump cards.]

Are almost all of them A- or A- grade materials?

Even the gems that Rin Tohsaka didn't take out at the beginning were all between B+ and C grade.

Yuto, who had never fought such a costly battle before, pondered briefly.

He had thought before that if he wanted to create a Jade Beast card, he would probably need a higher quality gem.

Now, with all sorts of high-quality gemstones laid out before him, perhaps his earlier guess can be confirmed.

"Then let's start by crafting a 3-star [Jade Beast Crimson Beast] to practice!"

Yu Du picked up a B-grade ruby ​​from the table and decided to use it as the main material.

Fun fact: Although the names of the Gem Beast cards all contain various kinds of 'jade', their actual prototypes are gemstones such as rubies, jade, and amethysts.

Therefore, to create the Ruby Beast card, he needs a high-quality ruby ​​as the main material, and as for the auxiliary materials...

Yu Du's eyes swept over the various materials on the table, pondering what to use as an auxiliary material for the refining process.

"Hmm... Ruby Beast is a LIGHT-attribute, Level 3 Fairy-Type monster, so there's no need to use overly high-level materials, otherwise it's easy to accidentally draw other higher-level monsters or some Spell/Trap Cards..."

So let's grind other low-quality rubies into powder and mix them with Rin Tohsaka's hair. But how do we deal with the angel race and the light attribute...?

Directly inject magic power?

If we categorize magic by its attributes, the four attributes of earth, water, wind, and fire can all be matched with the attributes of monsters in Yu-Gi-Oh! So, does the light attribute correspond to the void attribute, also known as 'ether'?

If that's the case, Rin Tohsaka's magic power, which has five attributes, and her hair should be able to provide enough ether, right?

There's really no good solution for the race issue for the time being, and he can't exactly find an angel to come down and pluck his feathers...

Having made up his mind, Youdu threw the chosen main ingredient, a B-grade ruby, into the vortex in the pot. Once it began to show signs of melting, he added pre-ground low-quality ruby ​​powder and three strands of C-grade hair from the five elemental masters for blending.

Low-star monster cards don't require overly complicated crafting methods; this is sufficient.

As the color of the vortex in the pot gradually turned crimson, yet within the crimson vortex were wisps of white, You Du quietly waited for the card to be extracted.

About 30 minutes later, Youdu saw a card float up from the vortex, revealing a reddish-brown edge.

It's an effects monster!

Tsk, he always gets this familiar feeling of opening a card pack at times like this.

You Du took out the card, subconsciously flicked off non-existent water droplets, and then looked at the card that had been created.

【Jade Beast and Red Jade Beast】

【☆☆☆】

[Angel Race/Light]

[Attack power: 300]

[Defense: 300]

really!

Looking at the red jade beast in his hand, which was still warm (not really) after being forged, You Du confirmed his earlier guess.

To create a Gem Beast card, you need higher quality gems as materials!

At present, a quality grade B should be sufficient. As for whether it can be replaced with a lower quality grade C gem... he doesn't know, and he doesn't plan to waste time experimenting for the time being.

The success of this [Jade Beast, Red Jade Beast] means that he still has a lot of work to do.

Following the previous steps, Youdu selected jadeite, sapphire, amethyst, amber, cobalt, and gem-quality citrine, which is commercially labeled with the transliterated English name 'topaz'.

He then went upstairs to the kitchen and got two pots to prepare the three cards together for refining.

Anyway, he has three fusion cards. Before, he didn't have enough materials, so there was no need to open more. But now that he has enough materials, he can open three with his A+++ level alchemy!

An hour later, using the same refining method, six more Jade Beast cards appeared on Yudu's table.

Jade turtle, amethyst cat, cobalt spinel eagle, topaz tiger, amber mammoth, and nephrite pegasus...

Including the first picture of the Red Jade Beast, there are a total of seven precious jade beasts, none of them are missing.

"The preliminary preparations are complete, so what's next..."

Yu Du turned his gaze to the design drawing of the gemstone sword.

[Design drawing of the Jewel Sword: A-]

[The design blueprints for a limited-edition Mystic Code inherited from the Tohsaka family by the Second Magician, Kyshua Zelrich Schbein'ogu, are known as the Jewel Sword because the blade resembles a faceted gem.]

Actually, he had planned to wait until the Holy Grail War was almost over before taking this thing out and using it.

After all, in the original Heaven's Feel route, when the Clock Tower was judging Rin Tohsaka because of the Greater Grail's descent and the Root Vortex appearing and disappearing instantly, the Jewel Mage intervened and saved Rin Tohsaka on the condition of exceptionally accepting three magician disciples.

Yuuto could be absolutely certain that old Deng was definitely spying on that parallel world where Heaven's Feel's ending was.

And he most likely noticed Rin Tohsaka when Shirou Emiya used the design blueprints of the Jewel Sword and the prototype of the Jewel Sword he had seen in his past memories to project the AZOTH Sword into the Jewel Sword.

And now, if we see him, who has never appeared in other timelines, also using the AZOTH sword as a vessel, and using the blueprints for the Jewel Sword, the seven ace jewels of Rin Tohsaka, and the jewel pendant as materials to forge a card...

Will the cards that are forged also attract the attention of the Gemstone Master?

If it attracts them...

A hint of disdain flashed in You Du's eyes.

The thought of an old man secretly watching him from another parallel world during the upcoming Holy Grail War made Yuto feel uneasy.

That's why he originally planned to use it towards the very end...

Tsk, isn't there any way to prevent the other party from spying on us?

Chapter Twenty [The Ultimate Gem, the Divine Rainbow Dragon]

Unfortunately, no.

Or perhaps it is possible, but Youdu doesn't know.

He shook his head and selected the materials he would use next.

First, there is the AZOTH sword, which serves as a carrier to bring all the materials together.

【AZOTH Sword: A-】

A short sword made of mercury, but not a weapon made for cutting and stabbing. It is a magical tool used to amplify the wielder's magic power and assist and enhance magic.

Originally, the AZOTH sword would only be rated B as raw material, but because it contained ten years' worth of Rin Tohsaka's magical energy, its quality was improved.

Secondly, there are gem pendants that provide immense magical power, used to increase the star rating cap of crafted cards.

【Gemstone Pendant: A】

[This is an artifact belonging to Tokiomi Tohsaka, the fifth head of the Tohsaka family. It contains the magical power of all the heads of the Tohsaka family since the first generation, and has now formed a vast magical power capable of bringing the dead back to life.]

Finally, seven A-grade ace gems of different colors are added as symbols, and a vial of blood from the five elements is added to define the attribute range of the card and reconcile any conflicts that may arise between the materials, thus enabling precise targeting.

The goal is to create high-star monster cards that simultaneously meet the following characteristics: gem, seven colors, and one of the attributes: earth, water, fire, wind, or light!

Forging—

Start!

Unlike the low-level monster cards and spell cards that Yuto previously crafted, the high-level monster cards contain a large number of materials, including many materials with conflicting properties and attributes.

Despite the presence of Rin Tohsaka's blood, which possesses transformative properties, as a harmonizing agent, accidents cannot be completely avoided, and Yuwatari must keep a close eye on things until the transmutation is complete.

He must intervene immediately if a conflict arises between the materials, using his own magic to absorb the excess portion of the material that is in a stronger position in the conflict and extract it as a card, in order to maintain the balance between the various materials in the process of alchemy.

It can be said that the process of forging a powerful card is also the process of forging multiple cards.

I just hope Rin Tohsaka still has enough magic power...

When Youdu put the ingredients into the alchemy cauldron one by one in order, the vortex in the cauldron was clearly divided into seven areas of different colors and sizes.

Well, it seems his work is about to begin!

Yuwatari reached into the red area with his palm. Perhaps because the [Gem Pendant: A] he had put in was also a ruby, this piece occupied the largest area. He then released his magic power, slowly guiding the excess ruby ​​material to be extracted and fused with his magic power.

Gradually, a green magic card materialized in his hand, which he then pulled out.

This is a spell card from the Jewel Beast deck, 【Jewel Contract】.

Baoyu's Contract

[Normal Magic]

You can target 1 "Crystal Beast" monster card in your Spell & Trap Zone; Special Summon that card.

The image shows a red gem floating on the ground; it's unclear whether it's related to the ruby ​​material analyzed in that document...

However, one card was not enough to extract all the excess materials, so Yuuto guided the extraction of excess materials again after drawing the card. This time, the extracted material was also a Spell Card from the Crystal Beast Deck, [Rare Value].

You Du didn't stop, constantly consuming magic power to extract excess materials to maintain balance, and gradually accumulating more cards on hand.

There are many cards related to Gem Beasts, as well as some cards related to Gem Knights, and some off-topic ones, such as the "Sage's Gem," which seems to be related to gems, but something just doesn't feel right.

The Sage's Gem

[Normal Magic]

[This effect can only be activated if you control "Dark Magician Girl". Special Summon 1 "Dark Magician" from your hand or Deck.]

The process of refining was unexpectedly long, lasting a full five hours before it was nearing its end.

Although he needed to intervene to maintain balance less and less as the process progressed, he still managed to obtain more than 30 cards during those five hours of training.

This was undoubtedly a huge drain on his magic power. If it weren't for his magic power rating being A+ and his Master Rin Tohsaka being an extremely skilled magician, he probably would have had to stop halfway through the process due to insufficient magic power.

Even without interruption, Yuwatari was still somewhat hesitant to think about Rin Tohsaka's current state.

Could he have been drained dry by now?

Yuto hesitated for a moment, but ultimately decided to look at the cards that had been refined first.
