Simulation: Starting from Under One Person

The plan to modify the Ten-Tails begins...

A barrier enveloped the area to prevent others from spying on it. The clone left the barrier and returned to Biyou Village to handle some trivial matters...

One of the things that's being pushed forward quite urgently is the "Academy of Extraordinary People".

"A floating island!"

Fang Rui rubbed his cheek, pondering what to do.

Manufacturing a standard-sized floating island is quite simple, but the problem is that it easily crumbles...

When flying over a city, if a few pieces of gravel fall into the city, it's not a big deal if they break streetlights or something, but if they hit a person...

"emmm..."

After careful consideration, I ruled out the standard type of floating island from the shortlist and started thinking about other types.

The "small floating island" type is also ruled out. Using it as a private residence is fine, but as for other uses...

Hmm, not really.

"...A magic weapon!"

After thinking it over carefully for a while, Fang Rui finally decided on how to create the floating island. Since it was a grand gesture, it naturally had to be a bit exaggerated.

and so……

The main body of the floating island is determined to be a magical artifact, a top-tier magical artifact specializing in defense.

"There's no specific requirement for the size of the island. We can expand the space using the Pot Heaven Technique, so whether it's bigger or smaller doesn't matter. But since it's about prestige..."

"Of course it has to be magnificent and spectacular!"

"A spectacle! It must be a spectacle!"

As he spoke, Fang Rui checked the inventory.

He's capable of crafting a top-tier magical artifact the size of an island; his inventory is quite impressive...

"Not enough!"

If it were to forge a top-tier magic weapon of average size, the existing materials would be enough to forge about ten, but a top-tier magic weapon the size of an island…

"My replica of the Swallow-Swallow Fruit can create some special metallic materials, but the 'Company' can provide the non-core materials!"

"As for levitation..."

"One type isn't good enough, let's get more..."

A single type of floating device means that there is only one way to break it. Once someone knows how to break it, the floating island is essentially held hostage, and whether it falls or not is in the hands of others.

To avoid this, we should have more devices and hide the matter.

This makes "how exactly the floating islands float in the air" a mystery.

"I currently possess five methods for making islands float: Devil Fruits from the world of navigation, magic and magical artifacts, some ninjutsu, and some special minerals."

"As for Devil Fruits, we'll need to travel to the world of navigation, but crafting the related devices is quite simple, so there's no rush. Magical artifacts will take time to refine, and as for the ores..."

"I need to go back to the Fox Spirit World! I wonder what stage of development it has reached..."

"We can also visit other worlds for a while and see if we can find other ways to float that can be replicated."

“During my absence, I can assign a task to the people at ‘the company,’ such as using the device that fuses the Swallow Fruit to create a special alloy.”

Fang Rui said it jokingly, then told Xu San about it via social media to prevent him from forgetting things after staying in other worlds for too long...

"So...should I leave now, or wait a while..."

Fang Rui thought about it carefully for a while. He stayed in Biyou Village to deal with various documents and trivial matters.

It's all work, with absolutely no rest time.

"Let me see if there are any plugins in the store that allow adjusting the flow of time between worlds."

"Assign tasks to the 'company' before leaving home, and return with the tasks completed—how wonderful!"

"Wow~ There really is one! That's great~"

After clicking to buy, there was very little money left, but fortunately, there was still a little bit left for the tickets.

"There's only one last thing to do with the preparations for leaving..."

A hair fell and transformed into "Fang Rui". The two looked at each other for a moment and nodded to each other.

Fang Rui left the room and went to other worlds.

………………

A bright moon hangs high in the sky, its gentle light spilling into the forest, where something seems to be hidden in the dark and quiet woods.

"The smell of blood..."

Having just emerged from his time-traveling state and before he could glean any insights from his previous experiences, Fang Rui smelled a stench of blood.

'Are they fighting beasts, or something else?'

With that thought in mind, Fang Rui headed toward the direction from which the smell of blood was coming from.

In the forest, pure white snow fluttered down, the cold wind howled, and a sound like weeping lingered in the air. Apart from that, there was no other sound—no howling of wild beasts, no rustling of branches and leaves…

A few minutes later, Fang Rui arrived at the source of the bloody smell: an ordinary, low-rise house.

The door was open, and the room was a bloody scene. Several corpses were scattered around, and a few spirits stood beside the only surviving girl, their faces full of anxiety.

"I see……"

Upon seeing this scene, Fang Rui immediately realized that he was in the time period when the plot was about to begin.

His gaze fell upon the earth, and through it, he saw something deeper, a relatively perfect underworld operating according to established rules.

"I need to discuss something."

Fang Rui, who communicates with the underworld through "spiritual connection," began to state his request: "I want to extend the lifespan of a few souls..."

Before the words had even faded, the underworld trembled slightly, as if rejecting Fang Rui's words.

"Don't want to?"

"Although it might offend some people to be frank, you can't stop me from resurrecting whoever I want."

Upon hearing this, the underworld trembled once more, as if it were saying something, appearing quite excited.

"What you say makes a lot of sense, but I have no interest in complying. If you don't agree to my demands, I'll beat you up!"

If it were a world of a higher level, Fang Rui wouldn't have such confidence. It's only because the Demon Slayer world isn't of a very high level that he dares to directly threaten the Underworld.

"And there won't be any problems with just a few people."

"How about it, give it a try?"

Fang Rui clenched his fist and gently rotated it a few times.

The Underworld: "…………" The threat was a bit too obvious.

After a moment of silence, the underworld trembled slightly, which could be considered a reluctant agreement to Fang Rui's proposal.

"Wise choice."

As he said this, Fang Rui turned his gaze into the room, meeting the eyes of several pairs of people.

"Yo~ Hello!" Fang Rui said calmly.

"Is he... greeting us?" Kamado Takekuma's gaze turned to his family.

"I guess... right!" Kamado Aoi's tone was somewhat uncertain.

While it's true that ghosts exist, it seems normal that there are people who can see spirits, but...

It's also possible that he's a pervert!

"Yes, I am talking to you."

Fang Rui affirmed their words, then beckoned them out: "Come out, I have something I'd like to discuss with you."

After exchanging glances for a while, the group left the room one after another and came to Fang Rui.

"Sir, what would you like to say to us?" Kamado Aoi asked.

"I can create a new body for you, so you will need to follow me."

'A new body!!!'

A seemingly ordinary sentence startled everyone, but the initial shock quickly dissipated. Kamado Hime calmly asked a crucial question.

"Why...why are you helping us?"

"Creating a physical body must be very difficult!"

Regarding Kamado Aoi's wariness, Fang Rui stated bluntly: "Creating bodies is very simple for me, as for why I should help you..."

“I believe good people should be rewarded, and you are good people in my eyes, so I want to help you. It’s that simple, there’s no other reason.”

What are your choices?

Kamado Aoi and the others exchanged glances for a moment, not immediately answering Fang Rui's question. Fang Rui's suggestion was very tempting to them, but...

Does money just fall from the sky?!

Even if Fang Rui says he doesn't seek any reward, can you accept that with peace of mind?

A debt of gratitude must be repaid!

But how can one repay the debt of gratitude for being given a new life?

Kawamoto Kuiji was torn, wanting to accept Fang Rui's kindness, yet also not wanting to accept it...

The reason they wanted to accept was that Takeo and the others were young and had not yet seen the vastness of the world; the reason they did not want to accept was that the debt of gratitude was as heavy as a mountain.

Perhaps sensing what Kamado Aoi was worried about, Fang Rui added, "After you are resurrected, come and work for me!"

Upon hearing this, Kamado Aoi finally made up her mind and agreed to Fang Rui's suggestion.

“Very good. Now follow me and leave this place to find the materials to create bodies.”

“But sister…” Takeo’s gaze fell on Nezuko Kamado lying on the floor, his face filled with worry, unwilling to leave.

"Don't worry, she'll be fine."
