Simulation: Starting from Under One Person

"So... do you think Leonardo da Vinci might do something? Like, change Olga Marie's body proportions?"

"Probably...not right?"

Roman hesitated. Da Vinci was usually very reliable, but sometimes... he wasn't so reliable.

After all, people who change their gender out of interest or curiosity have some issues in certain aspects.

Well, Olga Marie (male) has a pretty high chance of appearing!

Muttering to himself, Roman decided to go and check, just in case Leonardo da Vinci had a sudden whim and caused some trouble. After all, a genius's ideas can come on any time...

Roman then left the medical room, while Fang Rui continued reading books containing information about magic.

The magic knowledge gained from the clock tower is relatively traditional.

Chaldea's magical knowledge is far more advanced, and the two have significantly different research directions...

"In short, write it down first, and leave the integration and mastery to the clone."

Nothing particularly noteworthy happened afterward. Once the Chaldea maintenance work was completed, everyone began a full-scale search for the singularity.

A week later, a new singularity was discovered, and the group set off.

Based on the previous test, Fang Rui has confirmed that items from singularities can be brought back, but some special methods are required.

However, Fang Rui had no intention of going there personally. The first few singularities were relatively easy to handle, and his clone could manage them. He would take this opportunity to travel to other worlds to find what he needed...

………………

The Ninja World, Amegakure (Hidden Rain Village).

Due to a series of previous events, Amegakure's status has been elevated, and compared to the Five Great Ninja Villages, the only difference is its foundation.

Hashirama Senju and the others also shed their false bodies and took on real ones. Because their bodies were brand new, their strength decreased to varying degrees.

How is your daily life?

Upon finding Kaguya Otsutsuki, Fang Rui offered her words of concern, but his demeanor and tone were somewhat insincere, which was easily discernible.

"It's alright." However, Kaguya Otsutsuki's ability to read people was very low, so she didn't notice and answered with a cold expression.

"By the way, do you know how to create the Ten-Tails?" Upon hearing this, Fang Rui naturally changed the subject.

Black Zetsu: "…………"

“I don’t know.” Kaguya Otsutsuki slowly shook her head and explained, “Only a few people know the method to create the Ten-Tails.”

"Is that so..." Fang Rui nodded slightly to show that he understood. According to the information he had, each Otsutsuki responsible for planting the Divine Tree would have a Ten-Tails juvenile.

According to the conditions for planting the sacred tree, Otsutsuki usually work in pairs, one person is responsible for planting the tree and the other is responsible for serving as a sacrifice. In other words, two people per tree is the normal situation, and one person per tree is the abnormal situation.

Speaking of which, Fang Rui could vaguely guess why both Kaguya and Isshiki Otsutsuki possessed the Divine Tree...

The only difference was that after the last tree planting, their teammate was still in the resurrection loading bar, but the two of them had no intention of waiting, so they temporarily teamed up to go to other planets.

As for whether his guess was true, Fang Rui had no intention of verifying it; he was more concerned with something else...

"Kaguya, do you have a way to contact other Otsutsuki?"

"No!" Kaguya's tone was firm; even if there were something, she would never say it.

"Because you and Isshiki have been out of contact for a long time, the Otsutsuki clan will send people to investigate and retrieve the Ten-Tails in the near future, so..."

Upon hearing Fang Rui's explanation, Kaguya's expression darkened, but she still did not change her answer: "No."

After a pause, Kaguya explained, "You're also aware of the rules of the Otsutsuki clan, which is why the Otsutsuki usually don't communicate with each other, for fear that someone will try to steal their chakra fruits..."

"So, besides waiting, there's no other way?"

"Probably, anyway, there's nothing I can do."

Kaguya answered truthfully, then asked somewhat nervously, "How many Otsutsuki will come here?"

"If nothing unexpected happens, there should be three."

"Three..." Kaguya breathed a sigh of relief upon hearing this. Three Otsutsuki were still within the ninja world's tolerance. She could hold off one, her two sons should be able to take care of one together, and the remaining one should be no problem to leave to other ninjas...

After all, these ninjas were quite powerful.

Ignoring what Kaguya was thinking, Fang Rui turned his attention to another matter: "What do you know about dragon veins?"

Upon hearing Fang Rui's question, Kaguya thought for a moment, then shook her head and replied, "I don't know much about it. You should ask Hamura and Hagoromo about this..."

“That’s true.” Fang Rui nodded in agreement, then got up and left to find Hamura and Hagoromo.

"A dragon vein..."

"That is a mixture of natural energy and chakra. The original dragon vein was different from the current one. Its formation may be related to the divine tree."

Yu Cun explained his understanding of the dragon veins and answered Fang Rui's question: "As for your question about using the spacetime energy of the dragon veins to travel to the future, there is a chance of success, but the chance of failure is greater."

"And... even if you succeed, it might not be the time you want to go."

"Indeed." Fang Rui nodded slightly in agreement. Using dragon veins for time travel was indeed fraught with uncertainty.

Besides the dragon vein, there is another way to travel through time and space, which comes from the Otsutsuki clan's artifact, but Fang Rui doesn't know where that artifact is.

As for whether Kaguya Otsutsuki and the others knew about it, we would need to ask them.

After questioning, Kaguya Otsutsuki and the others were unaware of the existence of "Li". However, through divination, Fang Rui confirmed the location of "Li" and brought it to them.

"Future Travel - Anyone interested in participating, please sign up!"

Inside the meeting room, the people who had been summoned looked surprised, but after a brief moment of astonishment, they showed expressions of great interest.

Many people present were interested in the future; some wanted to know if they would end up with someone special, while others wanted to know if their hopes had been fulfilled...

For example, the pragmatic Orochimaru wanted to review his future experimental records, and he would simply abandon experiments that were impossible to carry out, as there was no need to waste time.

Therefore, quite a few people signed up.

However, the normal operation of the ninja village requires a considerable number of people, and not everyone can go together.

"There are video recorders that can record future visions. People who can't go can tell the people who can go if there's anything they care about, and have them watch it for them and bring it back on video."

After exchanging glances for a while, no one objected to the idea, and they quickly selected the person who would travel to the future.

"Should we invite the people from the other ninja villages?"

"no need!"

After saying that, the group set off, passing through the time tunnel constructed by the "Li" and arriving in the future world.

"This is... Konoha Village?"

Looking at the iconic Hokage Rock of Konoha Village, everyone guessed where it was located.

But why did it land in Konoha instead of Amegakure? Is there such a big difference?

"One, two... seven! There are seven Shadow Rocks... uh, Tsuna is the fifth generation! Ahahaha..."

"Big brother, be quiet!"

"Yes!"

"Minato, look! The seventh Shadow Rock is Naruto!"

"Yes, I saw it~"

"Huh? Is that... a train from the Land of Snow running on the tracks?"

Ignoring the voices of the people around him, Fang Rui cast his gaze upon Konoha Village, carefully examining it for a moment before turning his attention to Amegakure Village, surveying it from afar...

"I have bad news for you!"

"what?"

Upon hearing this, everyone turned their gazes toward him, their faces showing inquiry.

"We did arrive in the future, but... not the future we live in."

"What does that mean?" Some people didn't quite grasp it at first.

Others seemed thoughtful and had already made some guesses.

"Simply put, they are parallel worlds that are similar yet different."

"I don't understand." Many people shook their heads.

"It's okay if you don't understand. Simply put, it's about the future of us in other worlds, not the future of our current world."

"so?"

In response to everyone's questions, Fang Rui held up the "plow" and said, "Kaguya and I need to study it for a while, which should take some time. You are free to do as you please during this period. I will contact you before we leave."

The next second, a multitude of responses followed: "Understood.", "Got it.", "Anyone going shopping?", "Izakaya, yakiniku restaurant...", "Madara, let's go check out the Hokage Rock."...

Fang Rui and Kaguya left together, with Black Zetsu perched on Kaguya's shoulder in cat form.

"...Did this thing malfunction because it was soaked in water for too long?"

In Konoha's commercial street, Fang Rui and Kaguya walked side by side, their three pairs of eyes scrutinizing the tortoise-shaped "Li".

"How could such a treasure be damaged by water? It must be waterproof."

Black Zetsu spoke in a deep voice. In his opinion, even small gadgets made by ordinary people have waterproofing, so how could a top-tier treasure made by the Otsutsuki clan not have waterproofing?

Fang Rui raised an eyebrow slightly: "So... you think it's your mother who doesn't know how to use it?"

"I didn't say that!!!" Black Zetsu retorted excitedly.

"The treasure 'Li' is an intelligent item. It is very easy to use; just say it."

Kaguya said this, as she was quite familiar with the Noble Phantasm "Li".

"So, the reason the destination problem is that I didn't explain it clearly?"

After tilting his head and thinking for a while, Fang Rui gave up on dwelling on the matter and turned his attention to another thing: "Did you know that the treasure 'Li' can travel through worlds?"

“I don’t know,” Kaguya said. “The Noble Phantasm ‘Li’ is rarely used, and even if it is, no one cares whether it’s used to travel to another world; they only care whether the objective has been achieved.”

"Hmm." Fang Rui nodded slightly to indicate that he understood.

Fang Rui had finished asking his questions, and Kaguya voiced her doubts: "Why did you let them move around freely? They could have rested for a while before setting off."

"Just like you said before, no matter what the process is, as long as the ultimate goal is achieved, that's all that matters. Staying here will allow me to accomplish my objective."

"You mean... Otsutsuki?" Knowing what Fang Rui was planning, Kaguya quickly guessed what was about to happen.
