At about two o'clock in the morning, Xia Mu returned to the office. No one from the Federation was encountered on the way, and everything went smoothly.

Glancing at the bedroom, he saw that Sohivia was still sleeping soundly. He walked over gently and removed the message in her mind.

After checking the surveillance system and the office's security system, Xia Mu felt relieved after confirming that there were no signs of intrusion.

Then, he quickly turned on his computer, started the fake IP program he wrote, and started the intrusion into the federal database.

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

For those noble nobles in the upper city, the untouchables in the lower city are not worth the effort to manage, let alone the data in the lower city, as long as they are available.

Therefore, the database in Xiacheng District is quite easy for professional hackers like Xia Mu and Shiji to break into, and there is no need to worry about being tracked.

Although it will take some time... mainly to clear the traces, there will be no problem in replacing the data.

An hour later, Xia Mu successfully broke through the firewall of the Xiacheng District database and found the "Starry Night" data.

Then, he took out the brainwave collection device and gene extractor hidden in the secret compartment of his desk, got up and walked towards the bedroom.

Since Sohivia is a witch, he must confirm whether her brain waves and genetic sequence are different from those of humans in this world. If so, he must find a way to disguise her.

Fortunately, after some inspection, he confirmed that there was nothing wrong with both, and then replaced the data.

After Xia Mu had taken care of everything and cleared away all traces of his visit, the sky had brightened slightly, and it was now six o'clock in the morning.

"Wow~"

He yawned, moved his body, then stood up, closed the computer, and walked towards the bedroom again.

"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 already sat up, with confusion in her eyes.

"Natsuki...sir?!"

When the girl saw Xia Mu, her eyes were as dark as night and twinkling with starlight, and her eyes gradually widened with an expression of disbelief.

"The previous... wasn't a dream?"

She murmured softly, a mist appeared in her eyes again, her eyes were moist, and tears began to roll.

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

"Of course this is not a dream, Sohivia, it's really me... You must have suffered a lot to come to me, right? Tell me, what happened?"

This is what Natsuki wants to find out most right now...What happened to Alkaya?

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

"I don't know... Sir, I really don't know..."

Mentioning this, Sohivia seemed to recall some painful experience, and suddenly frowned with a very uncomfortable expression.

"At that time, Alkaya's fate was suddenly obscured. I couldn't see anything, and then... darkness fell!"

"dark?"

Xia Mu sat down by the bed, looking thoughtful, and motioned for Sohivia to continue.

"I don't know what it is, but it seems to corrode everything and change their inner being, making it distorted...

Humans, animals, witches...knowledge, will, memory...no matter whether they are living or inanimate things, once they are contaminated, they will become terrifying and violent."

As Sohivia spoke, her body began to tremble uncontrollably. It wasn't until Xia Mu gently held her hand and conveyed his warmth to her that she felt better, and then continued:

"The first person to be exposed to this thing was Arya. You should remember that she loved tinkering with weird things and studying ancient magic rituals. Perhaps it was during this process...she summoned this thing."

"Arya? Um..."

Xia Mu nodded, feeling that this was indeed possible.

[Witch of Secrets] Arya.

She is the most special of all witches.

Compared to "witch", Natsuki prefers to call her a "scientist".

Arya was usually gloomy and timid, so she locked herself in the research room all day long, reading some ancient books while tinkering with some weird "ritual circles" or "magic devices."

From time to time, various strange noises would come from her house, but whenever the noise stopped, she would always come up with something novel.

Moreover, Arya's inventions and ancient rituals can be put to great use in almost everything.

It can be said that she played an indispensable role in the liberation of Alkaya, including the establishment of various magic facilities after the liberation.

"What happens after that?"

"After that, the darkness's erosion of Alkaya deepened rapidly, and by the time we reacted, many people had already been infected.

Moreover, the only pure crystal vein that can purify darkness was completely destroyed under Arya's leadership. Since then, we have no way to fight against erosion."

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

Xia Mu finally understood the reason why Sohivia came to find him. No wonder, it turned out that the pure crystal veins had been destroyed.

"But that's not right. I only have such a small piece of pure crystal here. I'm afraid it will be difficult to solve Alkaya's problem..."

"Um, Sir Xiamu, I'm sorry. In fact, we... lied to you."

Mentioning this, Sohivia's face suddenly stiffened and she smiled awkwardly.

"ah?"

"Actually...the piece you took away is not an ordinary pure crystal, but...[Heart of Pure Crystal]"

"Heart of Pure Crystal?!"

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

"Heart of Pure Crystal"

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

Normally, it is no different from an ordinary pure crystal, but when the pure crystal is severely damaged, its effect will be revealed.

When other pure crystals are destroyed and lose their original power, all the lost pure crystal power will be gathered into the "Pure Crystal Heart".

And if the entire pure crystal mineral vein is completely destroyed, the "Pure Crystal Heart" will possess the power of the entire mineral vein, and at the same time turn into the "Crystal Mine Seed", becoming the seed for the mineral vein's recovery.

"You are treating me as an insurance policy..."

Xia Mu had a look of helplessness on her face.

"No, sir, that's not the case..."

But Sohivia shook her head firmly and then explained:

"Long before you left Alkaia, fate told me that this pure crystal heart would one day become the key for you to open the door of destiny and embark on the road of hope...
