At about two o'clock in the morning, Natsuki returned to the office, and there were no federal people on the way, and everything went well.

Glancing at the bedroom, Sosivia was still asleep, and he walked over softly and removed the message that had been in her mind.

After looking through the surveillance and checking the security system of the office, and confirming that there were no traces of intrusion, Xia Mu was relieved.

Then, he quickly turned on the computer, launched the fake IP program he had written, and started the invasion of the federal database.

Speaking of which, the level of defense of the federal database is actually quite high, but that is limited to the upper part of the city.

For those noble nobles in the upper city, the untouchables in the lower city are not worth the trouble to manage at all, let alone the data in the lower city, as long as there is one.

As a result, the database in the lower town is fairly easy for professional hackers like Natsuki and Timepiece to crack without fear of being tracked.

It will take some time...... The main thing is to clear the traces, but when it comes to replacing data, there will be no problem.

An hour later, Natsuki managed to break through the firewall of the database in the lower city and find the data of "Starry Night".

Then, he pulled out the brainwave collector and gene extractor hidden in the dark compartment of his desk, got up and walked towards the bedroom.

Since Sohivia is a witch, he must find out if her brainwaves and genetic sequences are different from those of humans in this world, and if so, he must find a way to disguise herself.

Fortunately, after some testing, he confirmed that there was nothing wrong with either of them, so he replaced the data.

When Natsuki had taken care of everything and cleared the traces of his visit, the sky was already slightly bright, and it was now six o'clock in the morning.

"Wow~"

He yawned, moved his body, got up, turned off his computer, and headed back to the bedroom.

"Huh? Are you awake? ”

Walking into the bedroom, Xia Mu was stunned for a moment, because he saw that the girl on the bed had sat up, and there was confusion in her eyes.

"Natsuki...... My lord?! ”

The girl saw Natsuki's eyes, which were as dark as night and twinkling with starlight, gradually widening to reveal an expression of disbelief.

"The previous ...... Isn't it a dream? ”

She muttered softly, and another mist appeared in her eyes, moistening her eyes, and tears began to roll.

Natsuki hurriedly stepped forward, smiled slightly, gently wiped away her tears, and then rubbed her head as before.

"Of course it's not a dream, Sosivia, it's really me...... You must have suffered a lot to come to me, right? Tell me, what the hell is going on? ”

This is the most important thing that Natsuki wants to figure out right now...... What the hell happened to Alkaya?

He remembered that everything was on track before he left, and Sosvia, as the Witch of Destiny, had her guidance that any danger or disaster should be removed before it arrived.

"I don't know...... My lord, I really don't know ......."

At the mention of this, Sohivia seemed to recall some kind of painful experience, and suddenly frowned, and her expression was very uncomfortable.

"At that time, Alcaya's fate was suddenly overshadowed, I couldn't see anything, and then ...... Darkness has fallen! ”

"Darkness?"

Natsuki sat down on the edge of the bed, thoughtful, and motioned for Sosylvia to continue.

"I don't know what it is, but it seems to erode everything and change it inside of it, distort it......

Humans, animals, witches...... Knowledge, will, memory...... Whether it is animate or inanimate, once contaminated, it will become terrifying and violent. ”

Sosivia spoke, her body trembling uncontrollably, until Natsuki gently took her hand and passed her temperature to her, she felt better, and then continued:

"The first to get her hands on this thing was Arya, and as you may recall, she loved to tinker with weird things and study ancient magic rituals, and perhaps in the process...... She summoned this thing. ”

"Arya? Hmmm......"

Natsuki nodded, thinking that this was indeed possible.

Arcia.

The most special of all witches.

Rather than a "witch", Natsuki prefers to call her a "scientist".

Arya is usually gloomy and socially phobic, and spends her days locking herself in the research room, holding some ancient books and nibbling there, while tinkering with some strange "ritual circles" or "magic devices".

From time to time, there would be all sorts of strange movements in her house, but whenever the movement was over, she would always come up with something new.

Moreover, almost everything of Arya's invention and the ancient rituals she has developed can come in handy.

It can be said that she contributed to the liberation of Arkaya, including the establishment of various magical facilities after the liberation.

"And after that?"

"After that, the darkness's encroachment on Arkaya deepened rapidly, and by the time we reacted, many people had already been tricked.

Moreover, the only pure crystalline vein that could purify the darkness was completely destroyed under Arya's leadership, and since then, we have no way to combat erosion. ”

"I see, that's why you came to me, because...... I have one last piece of pure crystal here? ”

Natsuki finally understood the reason why Soxivia had come to find him, no wonder, it turned out that the pure crystal vein had been destroyed.

"But no, I only have such a small piece of pure crystal here, I'm afraid it will be difficult to solve the problem of Alkaya......"

"Well, Natsuki-sama, I'm sorry, but we were actually ...... Fooled you. ”

At the mention of this, Sosvia's face suddenly stiffened a little, and at the same time showed an embarrassed smile.

"Huh?"

"Actually...... The piece you took away was not an ordinary Pure Crystal, but ...... [Pure Crystal Heart]"

"Pure Crystal Heart?!"

Xia Mu's eyes widened suddenly, and then he realized why his piece of pure crystal was so peculiar, and he could even separate "magic power" and "characteristics".

"Pure Crystal Heart"

It is the core of the entire pure crystal vein, and it can also be said to be the "soul" of the pure crystal vein.

In normal times, it is no different from ordinary pure crystals, but when pure crystals are wreaked havoc, its effects will be revealed.

When the other Pure Crystals are destroyed and lose their original power, all the lost Pure Crystal power will be gathered on the "Pure Crystal Heart".

And if the entire Pure Crystal Vein is completely destroyed, the "Pure Crystal Heart" will have the power of the entire Ore Vein, and at the same time turn into the "Crystal Ore Seed", becoming the seed of the vein's recovery.

"You're treating me as an insurance ......"

Natsuki's face showed a look of helplessness.

"No, my lord, it's not like that......"

But Sosivia shook her head firmly, and then explained:

"Long before you left Arcaya, fate told me that this Pure Crystal Heart would one day be the key to your destiny and your path to hope......

You need its help! ”
