Arknights' Lock of Heaven

The city's massive engine brings with it a vast living space.

Many important facilities are located underground.

It can prevent possible natural disasters, as well as more serious man-made disasters.

This includes some secret departments.

It's full of things that can't be brought to light.

Why is Xia Yu here? You'll have to ask Kal'tsit.

The so-called secret mission of Dr. Kal'tsit is not unfounded.

She asked Xia Yu to fetch a metal box.

It's not a mandatory task. Kal'tsit said before setting off that if there's enough time, we can consider completing this task.

But the priority is to rescue the doctor.

After getting rid of the Patriots, Xia Yu headed this way.

The map Kal'tsit provided was absolutely outrageous, with all sorts of facilities that should have been kept secret marked on it.

And it seems that she even placed the Doctor into the stone coffin herself...

At that time, there should still be people in Chernobog who remembered the former Director Kal'tsit, such as Sergei.

But she just swaggered in and let the doctor in.

Xia Yu couldn't even imagine how much she had infiltrated this city.

Xia Yu has already received the tin box she wanted, and the process was effortless.

To be honest, Merlin's Spirit Origin form is really useful...

Despite previous disdain, humans can't escape the "it's actually good" phenomenon.

The metal box in his hand had only a flimsy padlock, but he didn't intend to look inside.

This is called professional ethics.

Although they were underground, Xia Yu knew their location the moment Amiya sent out her signal.

Just kidding, how could such a specially made signal flare not have something added to it!

So—Xia Yu will arrive at the battlefield in three minutes.

32 natural disasters

The sky turned blood red, and boiling dark clouds surged amidst the flames.

A natural disaster is coming.

In this situation, even the Radiant Knights of Kazimierz fell silent in the face of such a scene.

A massive Originium plummeted from the sky, its head hanging low as it fell.

"Everyone—" Dobermann roared hoarsely, "Get cover..."

Rhodes Island's team is undoubtedly elite.

They have many veterans who survived the Kazdel Civil War, and powerful figures like the Radiant Knight Nearl...

However, even in the face of natural disasters, the ultimate calamities in the world, we are still powerless.

The distorted political system and the incredible technological advancements like mobile cities on this continent were forced out by natural disasters.

Why are there mobile cities?

Because they needed to avoid natural disasters.

Natural disasters could be a devastating earthquake, a cataclysmic thunderstorm, the eruption of dozens of volcanoes, sub-zero temperatures, or even meteorites and seas of fire falling from the sky.

They destroy cities and kill people; if a city is struck by a natural disaster, it is very likely that less than one-tenth of the people will survive.

The mobile city, a technology that seems extremely absurd to Earthlings, was forced out by the unique natural disasters on this planet.

Normally, it is a large city pieced together from dozens of districts. When it needs to move, it is broken down into dozens of districts of varying sizes and then pieced back together upon reaching its destination.

Moreover, the alloy needed to support such a massive city moving on land could be enough to build spaceships, right?

Of course, many of the technologies were simply unearthed from the ruins.

Natural disasters are an eternal problem for the world.

“So,” Xia Yu stood on the roof, looking thoughtfully at the giant Originium falling down.

"This thing, perhaps we can use it directly..."

Of course, now is not the time to think about this.

Amiya is still down there.

Little Amiya gripped the doctor's hand tightly, her ears perked up in tension.

She didn't know how many people on Rhodes Island would survive the natural disaster.

But it's too late now; held back by the Reunion Movement, they can't escape the reach of the natural disaster.

All we can do is pray.

Some things cannot be changed by human effort.

Amiya closed her eyes, huddled under the Doctor's arm, and nestled against a collapsed wall.

"Um, Amiya," the rumbling of the falling meteors continued, and the intense vibrations could be felt even through the ground.

The Doctor reached out and poked Amiya's cheek, his soft voice ringing in her ear, "Is this also a member of Rhodes Island?"

The voice was filled with confusion, but not with the fear of being caught in a natural disaster.

Amiya opened her eyes in confusion upon hearing this.

Before me was a dazzling screen of light.

The blazing sky covers seven rings!

In the Trojan War, which originated from Greek mythology, Ajax used a bronze shield covered with seven layers of cowhide to block Hector's javelin (it passed through six layers, leaving one layer unbroken).

After being elevated to a Noble Phantasm, its scope expands to include "conceptual weapons" that boast absolute defense against projectile weapons.

The defensive weapon that the Heroic Spirit Emiya excels at is shaped like flower petals, with seven petals in total, each of which is comparable to an ancient city wall.

It is clearly Ajax's Noble Phantasm, yet it has only ever appeared in the hands of Emiya Shirou.

Even now, Xia Yu still uses Emiya Shirou's Spirit Origin.

Ajax only exists in the description of this Noble Phantasm, how pathetic (laughs).

“It seems I’ve arrived just in time,” Xia Yu said, supporting herself with one hand on the Sevenfold Ring of Blazing Sky, and turned to smile slightly at Amiya.

Her long, flowing green hair danced in the wind, and her violet-like eyes were full of laughter.

Meteorites continued to fall from the sky, but when they struck the light screen held up by a single hand, they only created ripples.

"Leave the rest to me."

At this moment, the masked doctor clutched his chest and stared blankly at him.

so hot……

Amiya, oblivious to the Doctor's unusual behavior, nodded happily to Xia Yu and began arranging for medical operators to treat the wounded.

Although the Reunion Movement's siege caused great trouble for the Rhodes Island team, because they were all untrained thugs, Rhodes Island did not suffer any casualties under the protection of the battle-hardened veterans led by ACE.

However, many operators were still injured. Although the thugs were weak, there were simply too many of them.

"It's truly dazzling," Nearl exclaimed as he approached Xia Yu, carrying his warhammer and shield, looking at the light screen that almost covered the entire block.

She didn't know Xia Yu; she was on a mission when Xia Yu smashed through three decks of Rhodes Island.

Then, as soon as I got back, I was taken to Chernobog.

Dobermann and Amiya are checking on the operators' injuries.

"How much longer can we hold out?" ACE, this reliable warrior, didn't have much to say; he had to make all the remaining plans.

The doctor, no longer flustered, put his hands in his pockets and quietly observed the people who had stolen a moment of leisure amidst the natural disaster.

Having lost almost all her memories, she probably didn't fully believe Rhodes Island.

“I can drive this all day,” Xia Yu smiled slightly at ACE.

He had a very good impression of this older brother.

Originally, Chernobog's plan was for him to lead his squad to hold off Talulah, allowing the others to escape from Chernobog.

“I see,” ACE gave him a deep look, then relaxed a little from the tension caused by the battlefield atmosphere.

"That's good."

But this period of peace won't last long.

This minor natural disaster is almost over.

Yes, although the scene of the meteorite falling from the sky was spectacular, with buildings everywhere destroyed by the falling meteorite and crystal clusters tens of meters high standing on the ruins of Chern, it was ultimately a small natural disaster.
