Simulation: Start with one person

"So... do you think Leonardo da Vinci would do something? For example, modify Olga Marie's body proportions?"

"Should... not?"

Roman was a little hesitant. Da Vinci is usually very reliable, but sometimes... not so reliable.

After all, it is out of interest, curiosity, etc. People who change their gender are somewhat problematic in some aspects.

How can I put it~ The probability of Olga Marie (male) appearing is quite high!

Muttering in his heart, Roman decided to take a look to prevent Da Vinci from having a sudden idea and causing trouble. After all, genius' ideas come as they come...

Roman then left the medical room, and Fang Rui was still reading a book recording magic knowledge.

The magic knowledge gained from the Clock Tower is relatively traditional.

Chaldea's magic knowledge is much more advanced, and there is a clear gap between the two research directions...

"Anyway, write it down first, and leave it to the clone to figure it out."

Nothing special happened in the following days. After the repair work in Chaldea was completed, all personnel began to search for the singularity with all their strength.

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

After the last test, Fang Rui has determined that items from the singularity can be brought back, but some special means are needed.

But Fang Rui has no intention of going there in person. The first few singularities are relatively easy to deal with and can be dealt with by his clones. He himself will take this opportunity to go to other worlds to find what he needs...

………………

Ninja world, Rain Hidden Village.

Due to a series of previous events, the status of Yuyin Village has been improved. Compared with the five great ninja villages, the only difference is its background.

Senju Hashirama and others also got rid of their false bodies and replaced them with real bodies. Because their bodies were brand new, their strength was reduced to varying degrees.

"How is daily life?"

When he found Kaguya Otsutsuki, Fang Rui greeted him with greetings, but unfortunately his demeanor and tone were a little false, which could be easily seen.

"It's okay." However, Otsutsuki Kaguya's perception level was very low, so he didn't notice it and answered coldly.

"By the way, do you know how to make the Ten Tails?" Hearing this, Fang Rui naturally changed the subject.

Heijue: "..."

"I don't know." Kaguya Otsutsuki slowly shook his head and explained, "Only a few people have mastered the method of making the Ten-Tails."

"Is that so..." Fang Rui nodded slightly to express his understanding. According to the information he had, every Otsutsuki responsible for planting the sacred tree would have a ten-tailed larvae.

According to the conditions for planting sacred trees, Otsutsuki usually teams up with two people, one person is responsible for planting the tree, and the other person is responsible for serving as a sacrifice. In other words, two people and one tree is a normal situation, and one person and one tree is an abnormal situation.

Speaking of which, Fang Rui can vaguely guess why Kaguya and Otsutsuki both have sacred trees...

It was just that after the two of them planted trees last time, their teammates were still in the process of resurrecting, but they had no intention of waiting and formed a temporary team to go to other planets.

As for whether his guess was true, Fang Rui had no intention of verifying it. He was more concerned about another thing...

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

"No!" Kaguya said firmly, even if there was, she would not be able to say it.

"Because you have lost contact with Ishiki for a long time, the Otsutsuki clan will send people to investigate and recover the Ten-Tails in the near future, so..."

After hearing Fang Rui's explanation, Huiye's face darkened, but she still answered unchanged: "No."

After a pause, Kaguya explained: "You also know the rules of the Otsutsuki clan, so the Otsutsukis usually do not have contact with each other, and they are worried that someone will come to steal the chakra fruit..."

"In other words, there is no other way but to wait?"

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

Kaguya answered truthfully, and then asked nervously: "How many Otsutsuki will be here?"

"If nothing else, it should be three."

"Three..." Kaguya breathed a sigh of relief after hearing this. The three Otsutsuki are still within the tolerance of the ninja world. She can stop one. Her two sons should be able to solve one by joining forces, and the remaining one will be given to other ninjas. It should be no problem to handle...

After all, the strength of these ninjas is really not low.

Not paying attention to what Kaguya was thinking, Fang Rui turned to think about another thing: "What do you know about dragon veins?"

Hearing Fang Rui's question, Kaguya thought for a while, then shook her head and replied, "I don't know much. You should ask Hamura and Hagoromo about this kind of thing..."

"Yes." Fang Rui nodded in agreement, then stood up and left to find Hamun and Yuyi.

"Dragon veins..."

"It was a mixture of natural energy and chakra. The original dragon vein was different from the current one. The reason for its formation may be related to the sacred tree."

Hamura talked about his understanding of dragon veins and answered Fang Rui's inquiry: "As for you saying that using the space-time energy of dragon veins to travel to the future, there is a probability of success, but the chance of failure is greater."

"And...even if it succeeds, it may not be at the time you want to do it."

'really. Fang Rui nodded slightly in agreement. Using dragon veins to travel through time and space is indeed full of uncertainty.

In addition to dragon veins, there is another way to travel through time and space, which is a prop from the Otsutsuki clan, but Fang Rui doesn't know where that prop is.

As for whether Otsutsuki Kaguya and others know, they need to ask.

After questioning, Otsutsuki Kaguya and others were not aware of the existence of the "Plough", but through divination, Fang Rui confirmed the location of the "Plough" and found it.

“Those who are interested in participating in future trips, please sign up!”

In the conference room, everyone who was called looked shocked. After a brief moment of shock, they turned into interested expressions.

Many people present are very interested in the future. Some people want to know whether they will be with someone in the future, and some people want to know whether their expectations have been realized...

For example, the pragmatic Orochimaru wants to check his own experimental records in the future. Some experiments that cannot be realized are simply abandoned. There is no need to waste time.

Therefore, many people signed up.

However, the normal operation of Ninja Village requires many people, and not everyone can go together.

"There is a video recorder that can record scenes from the future. For those who can't go with you, if you have anything you care about, tell the people who can go and ask them to watch it for you, and then bring the video back."

Everyone looked at each other for a while, without refuting this method, and quickly selected the person to go to the future.

"Do you need to invite the rest of the Ninja Village?"

"no need!"

After saying that, the group set off and passed through the time and space tunnel built by "Plow" to reach the future world.

"This is... Konoha Village?"

Everyone looked at the Hokage Rock, the iconic building of Konoha Village, and already guessed where it was.

But starting from Amegakure Village, why did we land in Konoha Village? Is there such a big error?

"One, two...seven! There are actually seven shadow rocks...uh, Tsuna is the fifth generation! Ahaha..."

"Brother, be quiet!"

"Yes!"

"Minato, look, the seventh shadow rock is Naruto!"

"Well, I saw it~"

"Huh? What's running on the track... is the train from the Land of Snow?"

Ignoring the voices of the people around him, Fang Rui turned his gaze to Konoha Village and looked at it carefully for a while, then turned his eyes to the direction of Yuyin Village, looking at Yuyin Village across thousands of miles...

"I have some bad news for you!"

"what?"

Hearing this, everyone looked at him with inquiring expressions.

"We have indeed arrived in the future, but... it is not the future we are in."

"What do you mean?" Some people's minds couldn't wrap their heads around it for a moment.

Others were thoughtful and already had some guesses.

"To put it simply, it is a parallel world that is similar but different."

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

"It's okay if you don't understand. To put it simply, it's the future of other worlds when we go to it, not the future of the world we live in."

"so?"

In response to everyone's inquiries, Fang Rui raised the "Plough" and said, "Kaguya and I will study it for a while. It should take some time. During this period, we can move around freely. I will contact you before departure."

The next second, many responses came one by one: "Understood.", "Understood.", "Is there anyone shopping?", "Izakaya, barbecue restaurant...", "Madara, let's go to Hokage Rock to have a look."... …

Fang Rui and Kaguya left together, and Black Zetsu lay on Kaguya's shoulders, in the form of a cat.

"...This thing has been soaked in water for a long time? So is it malfunctioning?"

In Konoha's commercial street, Fang Rui and Kaguya walked side by side, looking at the turtle-shaped "plow" with three pairs of eyes.

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

Black Zetsu said in a low voice. In his opinion, some gadgets made by ordinary people are waterproof. How could the top treasures made by the Otsutsuki clan not be waterproof.

Fang Rui raised his eyebrows slightly: "So... you think your mother doesn't know how to use it?"

"I didn't say that!!!" Hei Jue retorted excitedly.

"The Noble Phantasm 'Plough' is a smart item. Its use is very simple, just say it."

Kaguya said this, she is relatively familiar with the Noble Phantasm "Plough".

"Does that mean the reason for the problem at the destination is that I didn't make it clear?"

After tilting his head and thinking for a while, Fang Rui gave up worrying about this matter and turned to focus on another matter: "Do you know that the Noble Phantasm 'Plow' can travel across the world?"

"I don't know." Kaguya said, "The Noble Phantasm 'Plough' is rarely used. Even if it is used, no one will pay attention to whether it travels to another world. They will only pay attention to whether the goal is achieved."

"Yeah." Fang Rui nodded slightly to express understanding.

Fang Rui had finished asking the questions, and Kaguya asked the doubts in his heart: "Why do you let them move around freely? They can set off after taking a short rest."

"As you said before, no matter what the process is, as long as the final goal is achieved, I can accomplish my goal by staying here."

"You mean... Otsutsuki?" Kaguya, who knew what Fang Rui wanted to do, quickly guessed what was about to happen.
