FGO system of the moon world

The Oil King was struggling in his magic position, and some unusual sounds came in from outside.

'Roar ——————

'

Clank—————— rub ———— boom!

First there was a roaring sound, and then it was like a medieval battlefield in a TV series, and the business of handing over weapons and weapons was transmitted, as if he was pulled into the battlefield belonging to gods and demons from a long distance.

This made him hold his head in both hands and silently lower his head.

Siegfried at Caster is very weak.

No one knows this better than he does. However, even if this is the case, since it is a heroic spirit summoned in the Holy Grail War, it is natural that many people will have the means that they do not have.

So.

Siegfried actually had other treasures besides his helmet.

Whether such a treasure existed or did not exist in the original Siegfried, the oil king himself is not very clear.

But at least he knew.

This may be a treasure born from a legend that is very strong.

Maybe you'll die if you start it.

But... If you really see that treasure, you may die with peace of mind.

The oil king thought for a long time, and finally picked up the dragon's blood on the table and stood up.

"The enemy has already fought here, so Caster, come with me. "

"I see. "

......

With this side of the situation, the side of Einzberen has finally completed its preparations.

Both Emiya Kiritsugu and Alice Phil stood next to a summoning circle, looking at Illya, who was in the middle of the circle.

"Illya, are you ready?".

With Alice Phil's voice full of concern, Illya slowly closed her eyes and pointed one hand in front of her.

"Hmm... I'm ready. "

Her voice is very steady, and at this time it has a somewhat ethereal feeling.

It was with this feeling that the spell on her body lit up, and she herself slowly spoke.

"Come back, Berserker in the name of the Command!"

Emiya Kiritsugu looked at the crimson magic array that appeared on the ground, and directly contacted Emiya Shirou.

"Shirou, come back with Saber, our members, we've successfully withdrawn. "

......

Listening to Kiritsugu's voice, Emiya Shirou was actually very embarrassed.

After all, Mordred was already scuffling with Artoria at this time.

With his eyesight, it was difficult to catch the figures of the two of them, not to mention that Mordred at this moment was like a berserker, directly grabbing Artoria violently.

But just when he didn't know how to speak, a strange voice was heard.

'Tartar ——————

'

......

The Oil King stood at the top of the tall building where his magic position was located, looked at Siegfei who was obediently standing in the center of the magic circle in front of him, and directly sprinkled the dragon blood in his hand on Siegfei's back, and then directly raised his hand holding the spell.

"I command you with the first mantra to go beyond the limits of your position. "

"In the name of the Second Command, I command you, Siegfried, not to leave the arena until you have the Holy Grail. "

"I command you in the name of the Third Spell, Siegfried, Dragon!"

As the three spells disappeared one after another, Siegfei, who had closed his eyes in the magic array, opened his eyes again.

A golden light burned from his eyes, and a pair of black horns grew on his head, and his hair became even longer, and dragon scales gradually grew on his body.

Like the whisper of a demon god, Siegfried slowly murmured after the change began.

"Drink, ——————".

With a low roar, Siegfried's body swelled to a height of tens of meters. Then, the pitch-black wings covered the sky and the sun, and the proud head was directly raised, revealing the enormity of its own existence.

"The Legend of the Dragon, Valrhona ——————

".

With the full activation of the Noble Phantasm, Valrhona, who could no longer be called Siegfried at the moment, let out her own roar directly into the sky.

"Tartar ————————".

......

PS: The treasure here is my original, and the main root is the legend of Feige about dragonization.
