Gucheng noticed that her small shoulders were trembling slightly.

Shame...... Or rather, timidity. Yukina is actually very scared, too. For the matter of giving his own blood to vampires, and about the unsuspecting exposure of his skin to the ancient city-

She is the Sword Witch of the Lion King's Agency. A demon attacker who was only sent here to monitor the ancient city.

Originally, vampires were just objects that should be eliminated for her.

But now, she plans to dedicate her body to the ancient city.

It's not so much for the protection of the people of Xianjin Island, but for the ancient city. In order not to let the ancient city regret his decision to use the power of the Fourth True Ancestor someday in the future.

"Learn, senior......?"

From the slender body of the slightly trembling girl, Gucheng felt her subtle warmth and comforting fragrance. Soft hair fragrance, and a slight body fragrance. And, the smell of blood-

The canine, no, the tooth hurts. The trigger that pulls the blood-sucking impulse is **. Vampires can only suck blood from attractive people of the opposite sex. And Yukina probably knew this, so she tried her best to tempt the ancient city in her own way. But

You really don't understand me, Gucheng thought.

"Ah, it hurts...... Learn...... Long ......"

Yukina doesn't understand how charming she is. And when he was with her, how much energy Gucheng spent trying to suppress his urge to suck blood.

The sharp teeth of the ancient city slowly bury into Yukina's body.

Yukina closed her eyes tightly and endured the pain. A faint breath leaked from Yukina's lips.

Gradually, his strength was lost from Yukina's body, which was held by the arms of the ancient city. And the red moon quietly shone on the figures of the two as if they had become one.

……

The place was built deep under the sea where no light could penetrate it, reminiscent of an eternal prison.

The lowest layer of the central stone gate is located in the bottom of the sea, about 220 meters below the surface of the sea.

The conical outer walls, built to withstand high water pressure, bear some resemblance to the mythical Babelta in atmosphere.

The role played by this class is somewhat similar to that used to curl the strings of the head of stringed instruments such as the violin. It can be conditioned by a steel wire extending from the four artificial base islands, thus controlling the vibration of the entire island, making it harmless.

The wires that lead through the door wall are all tied to the lowest pillars. The connecting wires formed by winding about 65,000 steel wires are about 1,650 millimeters in diameter. Exaggeratedly large winding machines control them with motors that rival the power of power plants.

The overwhelming quality of steel and the sense of pressure of the drive mechanism with explosive power. Add to that the intense water pressure that surrounds the entire building. These environmental factors convert the atmosphere that wafts in this class into a viscous and dense gas.

The airtight compartment that separates the lowest layer is making a mournful noise and is being pried open.

Tearing the seventy-centimeter-thick wall of armor through as easily as tin foil was a humanoid beast that shone with a rainbow light.

In the center of the beast's chest, the body of the host can be seen trapped inside.

It was a girl with long blue hair and pale blue eyes, an artificial lifeform Astarout.

Emerging from behind her was a muscular man wrapped in a robe.

Rotalingia's Annihilator Ludolulv? Oistaha was slowly looking at the bottom of the stone gate with emotion.

"The command is complete. Visually confirm the target. ”

Astarut told as if he was still in his own body.

The voice that had lacked modulation in the first place has now completely lost its feelings.

The Dependent Beast was originally a summoned beast from another world. In order to materialize it, the host must cut its lifespan. It also depends on the type of beast, but if you are a normal human, it is said that if you are summoned for a single moment, you will lose all your lifespan. The life of the host is nothing more than a mere sacrifice to the beast.

Even if the host is an artificial lifeform, there are no exceptions.

Astarout, who was adjusted to coexist with the beasts, was given a longer lifespan than ordinary humans. But even these are not many left. In order to attack the central stone gate, the power of the beast was used too much.

“……”

But Oistaha didn't even glance at such an Astarut, and just kept walking to the center of the lowest level.

That's the end of four steel wires that extends from the four bases of the artificial island.

The anchor blocks that hold all the headstock in place are small inverted pyramid-shaped metal cornerstones.

And a pillar that runs through the anchor like a stake holds it there.

It is about less than a meter in diameter. But that thing has to bear hundreds of tons of weight to connect to the island of the String God to this day.

It is a translucent pillar with a texture that resembles obsidian, the pivot stone.

"Oh...... Oooh......"

From Oistaha came a voice of lament and joy at the same time.

Trembling violently, he knelt on the spot. From the seriousness of looking up at the stone pillar, tears flowed endlessly. Eventually, his sorrow and joy turned into frantic laughter.

"Immortals usurped from the Sanctuary in Rotalingia...... I've been waiting for it to come back to us believers for a long time! Astarut! There is nothing standing in our way anymore. Pull out that hateful wedge for me and bring sanctions down on this island of decadence! ”

Oistaha let out a high-pitched laugh and gave a command to the Servant's artificial lifeform.

But Astarut did not move. It's just that it's still wrapped in the armor of the embodied beast, and he says in an emotionless voice,

"Command recognition. However, there is an error in the prerequisites, so I request that the command be re-selected. ”

"What?"

Gripping his massive battle axe, Oistaha stood up. Because he also sensed the reason for Astarout's refusal of orders. Who stands on the anchor block that is fixed as a pivot stone.

It was a teenager in a tattered uniform, and a girl with a silver spear.

"I'm sorry. Cancel the order for me, uncle. ”

The Fourth True Ancestor, Xiao Gucheng, was smiling with a tired expression.

"The remains of the saints of 'God' who served in the Church of Western Europe......"

The ancient city looked at the stone pillars known as the Central Stone with a look of pity.

In that translucent stone, someone's "arm" floated.

It was a withered, tiny arm like a mummy.

It bears terrible scars on its wrists as if it had been tortured. This is the body of a martyr who suffered for the sake of his faith and lost his life.

It is also the object on which the divine nature of God appears in this world, and therefore becomes the object of people's faith. It is said that the remains with a strong sense of sanctity will never ** and can cause all kinds of miracles.

And part of the body of such a saint is sealed in this stone pillar.

"It's called a relic. Sure enough, this guy is what you're for. ”

The ancient city said in a sighing voice.

The shallots broke through the strict defense procedures to investigate the secrets of the lowest layer of the island of the string gods. That is the existence of this holy relic. As a huge artificial city, the island of the god of the string is supported by the "miracle" caused by the holy relics.

"The city you call the island of the String God was designed about forty years ago."

Oistaha spoke in a low-key, majestic voice.

The tone of his voice has an air of majesty that is consistent with the teaching of a large number of believers.

"The spiritual veins - called dragon veins in the East, build an artificial floating island on the sea where they intersect to build a new city. This was an epoch-making plan at the time. Everyone thinks that the spiritual power flowing from the dragon veins will become the vitality of the citizens and lead the city to prosperity. But it was a challenge to build, because the power of the exposed dragon veins floating on the ocean was far beyond people's imagination. ”

To what he said, Gu Gu nodded silently.

The island of the string god was built on the grounds that I wanted to be far away from the mainland. That is the dragon vein, that is, the existence of the huge spiritual power meridian that flows on the surface of the earth.

The land built on the dragon vein will be filled with spiritual power. That alone can perform experiments on spiritual magic or magic that are more powerful than usual. This is a very ideal condition for the Demon Special Zone that conducts research on the Demon Race. The construction of the city on the dragon vein is necessary for the artificial island plan.

"The designer of the city, the string god is quite good. The artificial island, which is divided into four parts, east, west, north and south, is selected as the four gods in feng shui, and then organically combines them to control the dragon veins. However, there is a problem that cannot be solved even then. ”

"The strength of the pivot stone, is it ......?"

Oistaha nodded heavily in agreement to the murmur of the ancient city.

"As you say. According to the design of the string god Chira, a yellow dragon in the center of the island is needed as the head of the four gods, that is, the central stone that is the key to the connecting part. However, with the technology at the time, it was impossible to make building materials that could withstand such a load. So he broke the forbidden evil law. ”

"Sacrificial Building Materials ......"

This time it was Yukina who was moaning weakly.

But the dragon vein refers to the flow of qi in nature. The force of the storm will place an undue burden on the connectors of the artificial island. And if you want to be able to withstand the weight of the central stone, you can't do it with ordinary spells. It is necessary to have the power of a miracle that rivals God's. So

"The sacrifice he chose to sustain the city was the body of the noble saint who had been usurped from our church. As the base of the island where the demons are rampant, the act of trampling on our faith is absolutely not tolerable. ”

Oistaha silently declared in a voice that resounded from the bottom of his heart, and set up his tomahawk.

That's what it means when the words are finished. The purpose of the post-Euistaha was the recapture of the holy relic. There is no reason not to necessarily fight the ancient city them. That's why he answers the questions of the ancient city.

That is at the same time his justification - proof of his legitimacy.

For him now, any persuasion is useless. There is no way to overturn its resolve.

"Therefore, I will take back our holy relics with my strength. Please leave, Fourth True Ancestor. This is our holy war against this city. Even you can't get in the way—" (Markor )
