Arknights' Lock of Heaven

Hearing this, Tianhuo and Provence looked at Xia Yu's relaxed figure and nodded in unison.

It's clear that they are indeed very strong.

Even such a mutant cannot be detected.

The three watched as Xia Yu walked into the depths of the cave. The rock wall, which had not yet been cleared by the Originium Bugs, rippled like water after he gently brushed it over, eventually forming a cave entrance as tall as a person.

He walked in casually.

"Is this also an illusion?" Upon seeing this, Skyfire couldn't help but turn to look at Eyjafjalla, the expert.

“I…I don’t know,” Eyjafjalla said, somewhat frustrated by her question, her eyes blank. “I can’t see even the slightest trace of Originium Arts…”

"What the hell..."

Unaware of the entanglement of the three people outside, Xia Yu quietly moved to a suitable position.

He wanted to arrange a ceremony.

The ritual is derived from the Fuyuki City Great Grail.

Let's completely drain this volcano.

297 The All-Powerful Magic Trick

Driving away the Originium Bugs can indeed delay the volcanic eruption, but it won't last long.

The current Siesta volcano is like a car with its brakes removed, speeding down a slope.

While Originium Bugs were the main factor causing this situation, they are no longer important now.

Because this car is about to reach its end.

Destroying a booster might stop the car from accelerating further, but it wouldn't actually have that much of an effect.

Of course, if Xia Yu weren't available, Rhodes Island would only have this one option.

The volcano, which was originally expected to erupt in two to four weeks, has been rescheduled to erupt in three to six weeks. This may give people more time to evacuate, but it is not enough.

That's not enough for Xia Yu.

Whether it's a holiday, this attempt, or accumulating technical skills for the future, it's far from enough.

So, Pompeii and the like are just appetizers; the real focus here is the ceremony.

As is widely known, the Greater Grail of Fuyuki City is powered by the ley lines managed by the Tohsaka family, and it can be fully recharged every sixty years.

This world is where the Holy Grail War begins.

There were only four wars, and because almost no one won and no one made a wish, most of the magic power was left behind. The fifth war began just over a decade later.

The Holy Grail can be powered by ley lines; the three founding families designed various techniques when they created it.

In the FGO timeline, the victorious former director also obtained these items.

He left this knowledge to Chaldea, and in order to deal with the increasingly complex situation, Leonardo da Vinci found these techniques and modified them.

The method of slowly absorbing mana was changed to violent extraction, and applied to various Master-specific Mystic Codes to deal with the perilous situation of spirit particle transfer.

Although doing so will have a significant impact on the land, it's a singularity, and everyone understands what will happen after it's repaired.

Besides, since the pan-human history is about to disappear, why bother with all that?

In the end, all these techniques benefited Xia Yu.

Yes, Terra doesn't have ley lines, but Originium is much more convenient than ley lines!

We still need to find various nodes in the ley lines, and what about Originium?

You can just go up to the mine and suck it up.

Several Heavenly Locks emerged from the golden ripples behind Xia Yu and began to carve on the ground.

Magic arrays are not to be taken lightly.

After finishing the inscription, Xia Yu took out the Holy Grail from her chest, watched the golden cup float above the magic circle, and then guided magic power into the magic circle.

In an instant, golden energy flowed along the patterns of the magic array, converging and dispersing until it completely illuminated the entire array.

Become!

This shouldn't take much time, since it's a method modified by Leonardo da Vinci for emergency use, and it shouldn't take a long time to activate.

From this moment forward, the Holy Grail will continuously absorb Originium particles and convert them into energy.

Seeing this, Xia Yu nodded in satisfaction, then set up dozens of traps next to the Holy Grail before turning and leaving.

He has other things to do.

A volcanic eruption is no mild natural disaster; the explosive energy it generates is enough to terrify any city.

The large-scale absorption of Originium particles seems feasible, but it also means that countless Originium particles scattered nearby due to natural disasters in previous years will be highly concentrated in this area until they are completely absorbed by the Holy Grail.

This could potentially trigger other chain reactions, since no one has ever actually done this before. Although some people in Terra have proposed using the elimination of Originium Particles to avert natural disasters, most scholars scoff at the idea.

I think this is a fairy tale.

So no one has seriously studied what will actually happen.

Will there be any chain reaction?

Of course, there won't be any major disturbances, nor will it directly cause a volcanic eruption, but some minor changes are inevitable.

For example, a small earthquake.

Too much of it can also cause panic.

Therefore, Xia Yu needed to plan ahead and set up another magic array.

To stabilize the surrounding environment.

Of course, this is also thanks to Chaldea.

To achieve spirit particle transfer, it is not only the technology itself that needs to be overcome.

What if the relocation site has an extremely harsh environment? What if it's completely unsuitable for human habitation?

Most magicians are not good people.

But magicians are also among the most knowledge-seeking people in the world.

Artificial atmospheres, artificial ecosystems, climate control technologies, environmental remediation technologies, and so on have all made significant progress.

It's just that none of them can become mainstream.

After all, magicians don't dream of the stars; they seek the root. The application of these techniques is mostly in certain alternate dimensions or extreme environments.

This also means that the scope of these technologies is not very large; at least, they cannot change the ecosystem of an entire planet.

The older you get, the more things you have to consider, and the more complicated things become.

However, it is still possible to create a small barrier to maintain the environment.

Research into things like inherent barriers has also driven the development of these technologies.

As a human rights protection organization, Chaldea would inevitably acquire these technologies as reserves when conducting spirit transfer.

So it naturally fell into Xia Yu's hands.

"You've finally come out..."

Seeing Xia Yu reappear, slowly walking back from the sea of ​​Originium Insects, the three people waiting outside breathed a sigh of relief.

"And now?" Tianhuo looked at Xia Yu curiously. "Consultant, has your magical spell taken effect?"

"No, do you think I'm a god?" Hearing this, Xia Yu rolled her eyes at her. "You think you can just wave your hand and be done with it?"

"Just wait patiently, the ceremony takes time."

Hearing this, the group nodded thoughtfully.

A ceremony...?

Eyjafjalla looked at Xia Yu.

The rituals... the ancient witchcraft of the Sarkaz...

"So what now?" Skyfire looked down at the sea of ​​Originium worms and shrugged. "Are we supposed to deal with these?"

“No,” Xia Yu shook her head unexpectedly, “Let’s wait until tomorrow.”

“Bring the people of Siesta, defeat Pompeii and its tribe in front of them, and then tell them that this can buy them at least three months of time.”

At this point, Xia Yu shrugged, "There aren't any experts on the Siesta side, and Ceylon is just a recent graduate. I'm sure you can fool them all."

"After all, we can't let too many people know what's inside."

"At least, now is not the time."

After all, this is a great gift that I have prepared for the world.

It won't look good if you open it up beforehand.

"Alright, alright, you're in charge. After all, you're the advisor," Tianhuo could only suppress his curiosity upon hearing this.

"But seriously, I'm really curious about what you did. Can't you tell me a little bit?"
