Simultaneous travel: invincible from the beginning of the anime!

Chapter 787 Seiya: He has both an older sister and a younger sister, and they're not blood relatives!

The emergence of artificial light sources signifies the potential for developing unmanned technologies (equipped with fully artificial intelligence), which will play a crucial role in societal development.

However, after observation, Kikuoka Seijiro discovered that the artificial divination devices they had deployed were too well-behaved, so he ultimately decided to have Seiya and Kirito guide them.

After all, the initial artificial light-wielding beings, due to prolonged contact with programmed NPCs, would gradually have their thoughts gravitate towards those of the NPCs, which is quite detrimental to becoming fully artificial intelligence.

The best way to enable artificial light to learn and grow quickly is naturally to let it be guided by real humans, which is also one of the main reasons why Seiya and Kirito went to the Underworld for infiltration.

Of course, if it's just about guidance, Seiya and Kirito's job isn't considered dangerous.

The crux of the matter is that Kikuoka Seijiro told them that the people who infiltrated "UW" this time were not just the two of them, but also ruthless mercenary organizations from Europe and America.

The "UW" was developed by a company called "Ras," and the existence of corporate espionage within this company led to the exposure of the Yaoguang system.

Criminals attempted to steal the development data of "Ras" artificial light source to manufacture unmanned weapons, so they hired some professional mercenaries to try to enter the UW to find the key.

Due to an internal traitor, several account information was lost in the Underworld, and Seijiro Kikuoka speculated that the mercenaries would use these accounts to sneak into the Underworld.

In other words, if you encounter these mercenaries in the game, they will definitely attack Seiya and Kirito.

And that's not the worst part, because in order to facilitate the completion of artificial intelligence, Seiya and Kirito's memories of the real world will be sealed when they go infiltrating.

Only by doing so can artificial light be encouraged to grow in a way that is not influenced by external factors.

"So, those mercenaries you mentioned, will their memories of the real world be sealed away like ours?"

Faced with Kirito's question, Kikuoka Seijiro remained silent for a moment, then finally adjusted his glasses and said somewhat guiltily, "Probably... there might be difficulties, or perhaps not..."

After all, they only wanted to obtain the development data for the artificial light source; they didn't care about its growth or what the Underworld would become.

Kirito: "(_; The opponent is a mercenary who kills without blinking an eye, and he also has memories of the real world."

"And if we sneak up, we'll just turn into natives! Isn't that just sending us to our deaths?!"

Upon realizing how daunting his and Seiya's mission was, Kirito immediately launched into a tirade of profanities.

He had been wondering why Kikuoka Seijiro had agreed so readily to their outrageous demands. Turns out, this request was incredibly difficult!

"Those mercenaries probably don't know who has the key to the artificial light, right?"

Upon hearing Seiya's question, Kikuoka Seijiro nodded and said, "Although there were spies within Ras, fortunately some core secrets were not lost."

Furthermore, sealing your memories of the real world while sneaking into the Underworld isn't entirely disadvantageous for you.

Because of this, in the eyes of those mercenaries, you would also be considered natives of UW.

Once you've assisted the artificial light in reaching the final stage of its development, I will be outside helping you regain your memories and wipe out those mercenaries!

Seiya also remembered some of the plot from Sword Art Online: Alicization.

However, based on what Seijiro Kikuoka has said, the plot seems to have changed somewhat from what he knew.

The mercenary attack on "Ras," as far as Seiya knew, happened a few days after Kirito's infiltration of Underworld.

But they haven't even infiltrated UW yet, and the mercenaries have already obtained UW stealth accounts through an inside spy? "Since we already agreed to your terms, it's not good to go back on our word now."

However, I expect that while Kirito and I are infiltrating, you must ensure the safety of "Ras".

I don't want to repeat the unexpected incident from SAO where someone's consciousness was trapped in the game.

The mercenaries had already obtained UW's account, but Seiya couldn't guarantee that they wouldn't attack "Ras" again, so he could only remind Kikuoka Seijiro.

After repeated assurances from the other party, Seiya and Kirito entered the dedicated game pod and began their stealth mission.

"Lincoln's big head (link begins) —!"

The flow of time in the Underworld is completely different from that in the real world.

Six hours in the real world is equivalent to a year in the Underworld.

Seiya and Kirito's mission is to help the artificial Fluctlight develop into a fully artificial intelligence before the mercenaries discover it.

In order to have more contact and communication with the artificial Fluctlight and promote its growth, Seiya and Kirito were naturally assigned identities in the Underworld that were close to each other.

Seiya has memories of the Alicization arc, but unfortunately his memories of the real world are sealed, which makes him no different from Kirito, and he becomes a native of the game.

Under World, Lulit Village.

"Seiya, if you keep dragging your feet, your older sister might leave you behind."

If we don't get to Kirito and Eugeo soon, the sandwich's "destiny" will be used up.

In the village chief's house in Lulit Village, a girl who looked about 11 years old and was extremely cute, wearing a blue dress and a white blouse, with long golden hair tied up on both sides of her head, was carrying a bamboo basket of food and urging a blond boy on the table.

The blond boy is about ten years old and his name is Seiya. Although the cute blond girl calls herself her older sister, the two are not actually siblings.

The village of Lulit, where they lived, was a remote little village near the end of the End Mountains, known as the "Dark Territory".

The Dark Realm is a taboo subject for the human realm of the Underworld.

Any resident of the Underworld who sets foot in the Dark Realm will violate the Axiom Church's "Taboo List" and be taken away and executed.

The lovely blonde girl, named Alice Ziberuk, is the daughter of the village chief of Lulit Village.

Seiya was an infant found by a hunter from Lulit Village while hunting in the End Mountains.

When the hunter brought Seiya back to the village, the village chief of Rulit Village, Casford, had always wanted a son, so he adopted Seiya.

His original daughter, Alice, became Seiya's older sister because she was a year older than him.

Besides the two of them, Alice also has a younger sister named Seruka in the Casford family. Seruka is younger than Seiya, so she also calls Seiya her older brother.

As for "Kirito" and "Eugeo" mentioned by Alice, they are also children of Rulid Village, and also Seiya and Alice's childhood friends.

Eugeo's parents were farmers, while Kirito was an orphan.
