After choosing to leave, they regretted it.

But anyway, the result is good.

In the dark red sky, a ray of light as thin as a hair emerged.

Then the second, third, fourth...

Countless rays of light extended from all directions, almost covering the sky. They gathered together and flowed towards the safe zone like a river.

"This is……"

Aize didn't understand magic, but just by looking at it with his naked eyes, he could understand the astonishing scale.

I couldn't help but frown.

Soon, the experiment ended, the magic circle returned to normal, and the light covering the space dissipated.

Villian stood there, her expression unusually serious.

Aize quickly ran forward:

"How's it going? Did you find anything?"

"Well, that ancient ritual doesn't involve transferring magic power, but extracting it."

"Extraction?"

"Ah."

The witch waved her hand, and the thread-like light that had dissipated reappeared in the air.

Some markings should have been made to facilitate investigation.

In short, the number of these threads is extremely astonishing, converging from all directions, but a small number of them extend from nearby buildings.

Following the silk thread into the building, we discovered that its source was actually the blood slaves who had stopped moving.

"Sure enough."

Such a scene made Violet sigh softly:

"Ordinary blood plague will only cause the blood slave's magic power to dissipate uncontrollably, but when combined with this technique, the blood slave's magic power will be steadily extracted and sent to a certain place."

The silk threads in the sky just now were the manifestation of the blood slaves of the entire royal city having their magic power drained away.

This result made Aize shudder, and he immediately asked:

"how many?"

"Um?"

"How much magic power has been drained from the outbreak of the blood plague until now?"

In the current royal capital, a conservative estimate is that there are still around 100,000 blood slaves active.

On such a huge scale, magic power has been continuously absorbed for a whole month. Common sense shows that the total amount gathered together is astonishing.

"I can't say the exact amount, but if calculated based on the average human level, um... it's probably about twenty times my total magic power."

Villian's answer confirmed Aize's guess.

It even pushed its severity to an unprecedented level.

As the great witch, Villian is undoubtedly the strongest magician in the world, if we don't take into account the self-propelled turret of Silver Star. There is almost no spell that she cannot use.

And now, Arthur has gathered twenty times more than that with the help of the blood plague.

It's totally impossible to imagine what he's trying to do.

But what is certain is that if we don’t stop him, something terrible will happen.

Aize quickly asked:

"Can you track the destination of the magic power transfer?"

"Hmm... From what I can tell, it's heading towards the safe zone. But the technique's detection range is limited, so we might need to investigate a few more times to find out exactly where it's headed. So, should we do it? If we do, I need them to prepare."

This kind of exploration requires a lot of manpower, material resources and preparation time. Just the huge magic circle will take several skilled magicians several hours.

It’s not that we can’t wait.

But making such a big commotion in the safe zone is hard to say whether it will cause a riot.

Not to mention that the participation of the vampires is required. If the public knew about it, it would be even more outrageous.

But it seems there is no other way...

"……Um?"

Suddenly, Aize remembered something.

"Don't rush into it yet, there's a place you need to check first!"

Chapter 112 The Inside of the Wall

Leaving the others to pick up the pieces on the spot, Aize and Villian returned to the safe zone first and headed straight towards the palace.

From a distance, Heidi, who stayed in the safe zone, was seen wandering restlessly at the gate, and even the expression on her face was visibly anxious.

As soon as he spotted the two, he hurried over and asked impatiently:

"How's it going? Did you gain anything?"

The situation in the royal capital was at a stalemate and there was no progress. Heidi was even more anxious than Aize, and naturally she was looking forward to the results of this experiment even more than he was.

But Aize did not rush to answer. He just looked at her and then looked up at the palace behind him.

asked:

"If I remember correctly, when this palace was first built hundreds of years ago, it utilized both human and witch technology, right?"

Heidi blinked, obviously not knowing why Aize suddenly said this.

But he nodded:

"Yes, what's wrong?"

"A large amount of strengthening and anti-magic materials are mixed into the building materials, making it extremely strong physically. It also has a large number of permanent defensive spells, controlled by magic circles and magic circuits engraved in the walls, right?"

In this world, fortifications have to consider not only wars between humans, but also attacks from more dangerous large monsters, invasions from demons, and so on.

Therefore, when humans in this world build fortifications, they often seem a little crazy or even overdo it.

This palace is a good example.

Magic, high-level monster materials, rare minerals, etc.

A series of investments made at all costs make it extremely difficult to break from the outside in a physical sense.

When it came to such details, even Heidi was a little confused.

"Uh...Is that so? I'm not sure."

"Alicia, tear down the wall."

"Ah?"

The sudden order made the pink-haired girl, Heidi and Violet all stand there in shock.

Aize sighed softly and patted the wall beside him:

"Lift the surface of this wall for me. Use moderate force, and don't let the palace collapse directly."

"Okay, leave it to me~"

Alicia didn't understand the purpose of this order.

But she never needed to understand, she just had to do whatever Aize told her to do.

Gray tentacles appeared from under the skirt almost immediately, then extended rapidly, tearing through the air at a speed that broke the sound barrier, and slammed into the wall.

Such force could easily tear a house apart under normal circumstances.

But now, there is only a medium-sized hole left on the wall of the palace.

"It's so hard, try this one!"

He retracted his tentacles and transformed his right hand into a giant claw of a bear-shaped monster, pounding the wall again and again with even greater force than before.

The walls slowly began to crumble.

This act, which was almost like demolition, left Heidi, the real estate owner, completely confused.

She knew that Aize would not do this for no reason, but it was her own home that was demolished after all, and she knew nothing about it, which was a bit difficult to bear.

Then he asked cautiously:

"Um, Aize, what on earth is this..."

"As expected, the defensive spell wasn't triggered, and there weren't any alarms... Um, what did you say?"

Aize, who was thinking seriously about something, didn't hear what she said at all.

Heidi could only sigh and admit defeat.

"No, it's nothing, please feel free."

As soon as he finished speaking, accompanied by a loud bang, the well-decorated part of the wall collapsed, revealing the gray stone behind it and the densely packed patterns engraved on it.

There was a faint light in it, as if some kind of liquid was flowing.

Aize turned his head and gave Villian a look:

"Val, check this out."

"Ok."

Alicia stepped aside, making room so Miss Witch could examine the lines up close.

"Hmm...it seems to be a mixture of mercury, earth vein crystals, and dragon blood. This stuff is not cheap. Isn't it a waste to use this to build a magic channel?"

"Can you confirm the situation of the magic inside?"

"Let me try."

Villian raised her hand, facing the lines with her palm, and emitted a faint light.

After a moment, she whistled softly, turned her head and said:

"I won the prize, Aize. The magic power flowing in here is exactly that extracted from the blood slaves!"

"really……"

Aize nodded solemnly.

As a result, Heidi became a complete outsider, and her eyes kept moving back and forth between Aize and Violet in embarrassment.

asked:

"Um... could you explain to me what's going on?"

"Oh, well..."

Aize briefly explained the ins and outs of the previous experiment and the conclusion that someone was extracting magic power.

Then he pointed to the glowing lines on the wall:

"Now we can confirm that all the magic power extracted from the blood slaves in various parts of the royal capital has been gathered into the magic circuit of the royal palace."

"Oh, um..."

Heidi still needs some time to sort out the information.

Villian walked over to Aize and patted his shoulder fiercely:

"How did you come to think there was something wrong with the palace? Even I didn't notice the existence of this magic."

Villian is very sensitive to magic, but the palace is generally made of high-grade anti-magic materials, so if the walls are not demolished, there is no way to sense it.

In response, Aize just shrugged:

"Because there is something that I have felt strange about before."

"what's up?"

"The palace's defenses are far too lax."

In the past few days, Charlotte, as a vampire, has been going in and out of the palace as she pleases without any hindrance.
