Millennium Witch.

Chapter 133-132- Online Invisibility
For Yvette, deploying ordinary AI models is meaningless; she's not trying to install a chat application in her head. So, in choosing a direction, her goal is specialized AI—in other words, professional AI with low versatility but excellent performance in specific vertical fields.

After all, it is common knowledge that the data information used to feed AI is more valuable than the algorithm itself, and these things are monopolized by super companies. There is no other way but to spend money.

After investigating and consulting with Firefly, Yvette identified her target as "Sage's Core," a research-grade AI model in the pharmaceutical field sold by Black Tower Pharmaceuticals. It comes with its own database and its main function is to assist in the detection and analysis of the pharmacology of various materials. It is an essential tool for making magic potions, rune elixirs, and even active rune sets.

Of course, she had mastered the knowledge of runic medicine a long time ago and was fully capable of manually concocting many magic potions and runic elixirs. However, she had no need for them, and she only mastered the high-end theoretical framework. She had little knowledge of the basics of magic potion materials science, such as which materials could be used to make which potions. These were things that required rote memorization.

This means that if she wants to concoct potions herself, she has to manually test the properties of the basic ingredients first. It's like a top architect starting to dig clay from a mine to build a skyscraper. It's not that it's impossible, but who can handle that?

Therefore, to this day, she remains in a state where she possesses knowledge of runic medicine, but faces numerous difficulties in putting it into practice.

Now that she has this, things are much easier, and she can finally refine and mix magic potions, even though she's still an unlicensed doctor.

……

In July, in a small county town near Fusi River, Yvette, Liana, and Firefly rented a small apartment and lived a low-key life for two months.

In the past two months, the attention given to the Fusijiang tragedy has waned considerably. Neither the Rusty Bone intranet nor the Black Tide Continent's international network has mentioned it anymore.

However, neither the Rustbone government nor the Holy Spirit Cult has ever relaxed its internal search efforts, especially in the small county town where Yvette lives. There used to be no surveillance cameras at intersections, but now shuttles are flying around the streets and alleys, and it's obvious who they're after.

But it's understandable. Who could accept a monster that can cause hundreds of thousands of casualties running rampant in their own country? Even if the Pope of the Holy Spirit Cult tolerated it, the Prime Minister and Cabinet of Rusty Bones certainly wouldn't.

So, in order not to provoke the Rustbone officials, Yvette kept a low profile here, like an ordinary apothecary, placing glass bottles containing various liquids in her room every day and familiarizing herself with the combinations of magical potions.

Of course, there was another reason for staying here: it was still very close to the Frost River, and Yvette was worried that if she continued to move further away, she would come into contact with the boundaries of the dream world.

Although Zero had mentioned that this was not a completely fake world, out of caution, she preferred to spend the rest of her time practicing potion-making here rather than taking any risky actions.

And so, autumn arrived.

With less than half a month left in the dream, the Rustbone authorities relaxed their pursuit of Yvette and her two companions, and the streets returned to normal, with the shuttle flashing red and blue lights nowhere to be seen.

At this point, Yvette finally decided to take Liana and Firefly away from here, cross the entire Rustbone, and head towards the east coast of Black Tide Continent. Her ultimate plan was to take a smuggling route to another continent.

The process went very smoothly.

Using hacking techniques to evade surveillance and deliberately choosing various rural dirt roads, the group got closer and closer to the East Coast.

Meanwhile, as the spatial distance from Fusjiang continued to increase, Yvette also confirmed one thing.

That is, the dream world is truly complete, not limited to the small area where you enter the dream; it seems to have no boundaries.

In other words, it's highly likely that it wasn't a dream, nor was it a fragment of memory left to her by Zero. Otherwise, how could you explain creating such a large, complete world with meticulous logic and order in every detail through your memories? The original owner wasn't an omniscient and omnipotent god.

But this led to another problem that puzzled Yvette.

Why are the people she sees different from others?
During her first dream, she noticed that the people in her eyes were somewhat blurry and semi-transparent, which led her to immediately conclude that she was not in the real world, but had entered a false dream.

Later, in the Blackwater District of Ish City, after entering the dream with Rosalyn, she discovered that Rosalyn's body had not become illusory. This further reinforced her belief that she possessed the ability to distinguish between a fake person and a real person at a glance, and that she could tell even if there was a second person entering the dream.

But now, the dream world is not just a dream. Zero looks like a mannequin, but he doesn't seem to be a native of the dream world.

Could it be that my strange vision isn't used to distinguish between real people and fake people?
Actually, there are no fake people, they are all real people?
With this thought in mind, one day, in a small town inn along the way, Yvette looked at the pedestrians on the street again. Then she saw, as if ripples were spreading before her eyes, the bodies of those pedestrians who were somewhat transparent and blurry suddenly became clear, as if she had returned to the real world.

Yvette was stunned. Several seconds later, with a thought, the bodies of the pedestrians became illusory and transparent again.

Yvette was even more surprised, thinking, "So this can be switched?"
Why wasn't this discovered before? Was it because we lacked awareness about it?

Immediately...

She thought of something and looked down at herself.

The next second, she saw her body begin to become illusory and transparent, just like the pedestrians on the roadside.

She turned to look around the room. Fireflies were charging themselves with magic wires in the corner, and Liana was reading a linguistics textbook on Emerald Language. As if sensing her gaze, Liana raised her clear eyes, blinked, and asked, "What's wrong, sister? Is there something on my face?"

Yvette said, "No... it's just that you're too beautiful, Liana."

Liana was still just a child and didn't know how to hide her feelings. Her fair face instantly flushed red, and she lowered her head shyly, her fingers unconsciously twisting the hem of her clothes. "N-no, you're the one who's prettier than me, sister..."

Yvette smiled, looked away, and thought to herself, "As expected, only I can see this visual effect..."

But soon, she thought of something else.

If she can use this method to disguise herself as a local in the dream world, then wouldn't Zero be able to do the same thing?
What is this, online invisibility in virtual reality games?
……

Ten days later, Yvette, Liana, and Firefly's cyber wanderings came to an end in a port city on the east coast of Black Tide Continent in the Rustbone Free State.

Since it was almost time to leave the dream, Yvette gave the two some instructions, left them enough money for living expenses, rented a house, and quietly waited for the time to end the dream.

As the scene before her dissolved, blurred, and was swallowed by the boundless darkness, before slowly gathering back into light, Yvette opened her eyes. What she saw was a rusty, moss-covered ceiling, and the cold, damp air she inhaled made her immediately certain that she had finally returned to the post-apocalyptic world, to the Water Tower Kingdom of the Machine Race.

Yes, my height has returned to normal, that's great.

She stood up and saw the remaining earthen wall she had magically created standing beside her. She tore it apart, gracefully soaring upwards through the air, emerging from the entrance to the underground ruins. Sunlight generously streamed down, illuminating the submerged city. The crystal-clear river reflected shimmering light, like schools of golden fish.

She let out a long breath, thinking that although the post-apocalyptic world was a savage world governed by the law of the jungle, it was still more suitable for her than the pre-apocalyptic world, at least it wasn't as oppressive.

Of course, it's possible that she felt oppressed because she was being hunted and had to wander around with Liana and Firefly. Ordinary people's lives were probably a little easier than hers... probably.

Then, remembering something, after leaving the underwater ruins, Yvette flew low along the flooded streets, quickly leaving the Water Tower Kingdom and entering the surrounding desolate area. She precisely arrived at several coordinates she had set in her memory and began to carefully dig downwards.

Each excavation was accompanied by the passage of time. After repeated attempts, yet still unable to find the time capsule buried in the dream, Yvette was finally certain.

Indeed, dreams are an independent world, and actions taken in dreams cannot affect reality or change the future.

Yvette, on the contrary, felt a sense of relief. She had no love or sense of belonging to the Origin Civilization; she simply needed their technology. If she had accidentally canceled the apocalypse and changed the future, her fate of meeting Rosalind and Dugrabi might have been altered, which was the last thing she wanted to see.

For now, she's content with maintaining the status quo.
