I, Yu Uchiha, am devoted to cultivating immortality

Senju Tobirama recalled his experiences in the future, and he remembered more and more details.

He murmured: "Uchiha Obito controlled Nagato of the Akatsuki organization, the resurrected Uchiha Madara controlled Uchiha Obito, and finally Black Zetsu controlled Uchiha Madara..."

"And the resurrected Otsutsuki Kaguya was easily sealed. There were so many coincidences during this period that she couldn't hide her feeling of being plotted."

"The only person who can calculate the existence of the goddess of Mao..."

Qianju Tobirama's voice was loud and trembling at the same time: "It's possible, it's really possible."

"As soon as Otsutsuki Kaguya was resurrected, the Sage of Six Paths took action immediately."

"He silently helped Uzumaki Naruto and Uchiha Sasuke, making them become six-level powerhouses, and guided them to seal the goddess Uzumaki to save the world."

"And these two children are the reincarnations of the sons of the Sage of Six Paths."

"Haha, these are two reincarnations of the right age and status. They were accurately prepared 16 years in advance. I really don't know how much work and hard work went into such precision."

Uchiha Yu smiled and said, "Yeah, it's hard to imagine."

"Based on this result, it can be inferred that the Six Paths Sage's control of Black Zetsu and the situation in the ninja world are absolutely perfect!"

Senju Tobirama's emotion suddenly stopped, his eyes flashed with fear, and he looked at Uchiha Yu.

Uchiha Itachi raised his eyebrows and said with a smile: "Don't worry, we, the Sage of Six Paths in the ninja world, have lost control of the ninja world."

"In the past two years, I have changed a lot of things, killed a lot of people, and destroyed most of the Six Paths Sage's layout in the ninja world."

"I think he shouldn't have the energy to pay attention to people and things that have nothing to do with me."

Qian Shu Feijian said in surprise: "I see. No wonder you only stay in this secret realm of Loulan now, but this is too miserable."

Uchiha said leisurely: "I really have to hide in the Loulan Secret Realm so that I can 100% avoid the sight of the Immortal of Six Paths. It is really uncomfortable to stay in the Loulan Secret Realm."

Thousand Hands Tobirama: "You left the Loulan Secret Realm just now when you picked me up. It seems that it's okay to go out for a short time."

Uchiha Yu smiled: "Nidaime, how did you know it was me who picked you up?"

Senju Tobirama was no longer confident: "Shadow Clone Technique, no, Wood Clone Technique?"

Uchiha Yuu: "Wood Clone Technique."

Senju Tobirama: "I didn't realize it at all. You developed this technique so perfectly. It's incredible."

Uchiha Yuu: "Otherwise, how could we deceive the Sage of Six Paths?"

"Right."

Senju Tobirama continued to talk about his experience in the Fourth Ninja War.

Narrating that when four Hokage appeared on the battlefield at the same time, Senju Tobirama sighed: "That boy Orochimaru actually reincarnated the second generation Hokage of the future world into the Hokage."

"Seeing myself on the battlefield scared me."

"You told me that the Nine-Tailed Jinchuuriki from the future world came to our world, causing our Nine-Tailed Jinchuuriki to change accordingly."

"The two Nine-Tails Jinchūriki have problems even before they meet. If the two Senju Tobirama meet in the form of reincarnation, God knows what problems will arise."

“In the end, nothing happened, but it piqued my interest.”

"After careful comparison, I found that they are both reincarnations of the filthy earth of Senju Tobirama. His and mine have exactly the same soul fluctuations, but there is a huge difference in chakra, and the difference is determined by the sacrifice."

"It looks like two Senju Tobirama reincarnated from the dirty land, but they are actually two different sacrifices. There is no possibility of interfering with each other."

He went on to tell the story of the battle between the four Hokage and Uchiha Obito, as well as Uchiha Madara's domineering power after resurrecting and regaining the Rinnegan.

Senju Tobirama said disdainfully: "This is the first time I have seen Madara Uchiha like that, holding his brother's head on his chest and talking non-stop about Hashirama, Hashirama and Short."

"How disgusting!"

Uchiha Yu smiled and said: "Is Uchiha Madara great?"

Senju Tobirama was silent for a long time before sighing: "Awesome, Madara Uchiha gave me only despair, which is far more terrifying than Kaguya Otsutsuki who later used his body as a sacrifice to break free from the seal."

"That woman is more powerful, but she doesn't give me the feeling of any pressure. She is completely clumsy and doesn't know how to fight."

Uchiha Yuu's eyes sparkled with yearning: "If I have the chance, I really want to fight Madara who becomes the Ten-Tails Jinchuuriki. It will be fun."

But Senju Tobirama's story ends here. When Madara Uchiha cast the Infinite Tsukuyomi, he, like everyone else, was hypnotized and suspended.

By the time Senju Tobirama broke free from the shackles of the sacred tree, the Six Paths Sage had already channeled the five shadows of the past, summoning Team 7, the nine tailed beasts, and the dying Uchiha Madara from the enclosed space of the first ball.

It was at this time that the Immortal of Six Paths appeared in front of the crowd and saw Thousand Hands Tobirama.

"After seeing the reincarnation eye of Sage of Six Paths, I completely fell into a deep sleep. When I became conscious again, the only people I saw were you and Miwa Masato Sage."

As a reincarnated body of filthy soil, Qianju Tojian couldn't break out in a cold sweat, but the fear in his eyes almost turned into reality.

He said to Uchiha Yu: "The feeling brought to me by the Sage of Six Paths is terrible. I even feel that I am a lamb to be slaughtered and the Sage of Six Paths is the shepherd."

Uchiha Yu comforted: "You don't have to worry about the Six Paths Immortal in Loulan Secret Realm, and this feeling is most likely because you are a dead person, and the Six Paths Immortal is the Lord of the Pure Land."

"When I master the resurrection technique and the second generation comes back to life, I won't have to worry about the Sage of Six Paths."

After sending Senju Tobirama to rest, Uchiha Yu sat alone in front of the gate of the world.

He thought silently, comparing Senju Tobirama's narration with his own memory to check the differences between the two versions of the Fourth Ninja War.

Uchiha Yu concluded that there was no difference between the two. Even if there were slight differences in details, they were within a reasonable error range.

After all, there may be errors and inaccuracies in both my own memory and Qianju Feijian's memory.

Since there is no difference, it means that the major event that tore out a new parallel time and space occurred after Senju Tobirama was discovered by the Sage of Six Paths.

Because the specific time is unknown, Uchiha Yu cannot determine which era was specifically affected. It cannot be that the incombustible era has been changed.

Regardless of whether it was true or not, he couldn't make a judgment anymore, because after the Fourth Ninja War, nothing important happened in the ninja world.

In other words, this story has come to an end and entered a boring period of peace. Peaceful times are always step-by-step, and it is almost impossible to tear apart parallel time and space.

The possibility of causing that time shock from the future is really slim.

Either there was an accident in the battle at the Valley of the End, and one of Uzumaki Naruto or Uchiha Sasuke died, or even both of them died together, resulting in the loss of the deterrent power of Konoha Village, and long-term peace was not able to come.

Either the Otsutsuki clan from outside the world arrived early and started the interstellar war in advance.

Either the Six Paths Sage Otsutsuki Hagoromo changed his mind after learning about Uchiha Yuu's information and shifted his attention to parallel time and space.

Uchiha Yuu had the urge to go to the future to see for himself, and there was a story that happened there that he had no idea about.

But he soon gave up this unreliable idea and turned to thinking about the next time travel experiment.

Senju Tobirama gained a lot from this time travel. In addition to detailed information about the future, there is also the cause and effect of the future Six Paths Sage, and a large amount of time travel data.

With these data, Uchiha Yu has a more thorough understanding of time and a more accurate positioning of parallel time and space.

Part of the data related to time travel is the soul change data of Qianju Tojian, which is very critical.

Senju Tobirama said that he had studied his future self and believed that he and the future had no influence on each other, but he was wrong.

It is true that the body and chakra have no impact, but the entanglement in the soul is inevitable.

Senju Tobirama was unable to discover it simply because his level was too low and he lacked his own data before eating.

And Uchiha Yuu was strong enough and had complete data, so he easily discovered the changes in Senju Tobirama's soul.

Therefore, he deduced a soul traveling method that was less expensive and dangerous, and used the attraction of the same soul across time to achieve soul traveling at the minimum cost.

He found that he could complete two time-travels at the same time, one was the body's time-travel, and the other was the soul's time-travel.

The difference is that physical travel does not need to consider the state of the target time and space, while soul travel can only possess oneself in the opposite time and space and temporarily merge together.

This is a very restrictive way of traveling. It is not suitable for many people, and the data that can be harvested in one round trip is not much. However, the consumption is surprisingly small, and the price-performance ratio is very high.

The most important thing is that sending souls through time does not require the traveler to come to the Loulan Secret Realm.

Through the divine court meeting in the Purple Mansion world, or grabbing souls through causal connections, Uchiha Yu can pull anyone in the ninja world to the gate of the world and then send them out.

As for how the soul traveler returns...well, this is really a difficult problem that requires research and experimentation.

Uchiha Yu fell into deep thought.

[Who can I deceive and become the first experimental subject of soul time travel? 】

In fact, guinea pigs are not hard to find.

The new system of Konoha Village was very successful. The fourth generation Hokage Orochimaru gained benefits beyond imagination after kicking away the daimyo and nobles and leading Konoha ninjas to directly take over the Country of Fire.

A small portion of the new benefits came from the nobility and daimyo from taxes they had withheld in the past, amounting to about nine times the amount appropriated.

That's right, in the past, the ninjas and nobles of the Fire Country divided the tax money not 50-50, nor 30-70, 28-20, but 19-10.

The ninja village who controls violence gets one, and the noble who directly manages money gets nine.

Of course, the nobles and daimyo were talking about four or six points, and the Ninja Village took six, and used this as an excuse to make it more difficult for the Ninja Village to make additional payments.

The daimyo and the nobles of the five major countries have a tacit understanding, and they silently abide by the two sets of accounts, the actual one-nine points and the apparent four-six points, and deceive the five strongest Kage in the ninja world.

A weak person is like a shadow in the wind, and will be deducted even more until nothing is gained.

As strong as the Raikage, he can win at most 28 points, but he is promoted as a "cruel" and "monomaniac" who abuses the nobles and is a lunatic.

Of course, under the new system, taxes are just a small expense.

Now the majority of Konoha Village's income comes from industrial profits, which are the infrastructure completed by the ninjas, which has given a huge boost to the agricultural business of the Fire Country.

The amount of profits that Konoha Village derived from related industries increased by at least ten times compared to the total amount of taxes.

The benefits of directly controlling the country were so huge that every ninja village began to copy the gourd.

But not all ninja villages can solve the problem of nobles.

Yunyin Village was already strong, and Raikage directly killed all the nobles and monopolized the interests of the Country of Thunder.

Kirigakure and Sand Hidden Village were severely weakened, but there were no internal differences. They successfully resolved the nobles and completed the changes to the new system.

Only the unlucky Iwagakure Village turned into a self-division due to the serious infiltration of nobles, causing the entire country to collapse, and even attracted the covetousness of Konoha Village.

In short, in the second wave of reforms led by Konoha Village, most ninjas have gained huge benefits, but a small number of ninjas have also felt dissatisfied.

These ninjas are not dissatisfied with their income, but are dissatisfied with the increasingly peaceful living environment and boring construction tasks.

There are a very small number of people among humans who are born fighting madness, and the proportion of fighting madness among ninjas is much higher.

They want to fight powerful enemies, bathe in blood, and experience the thrill of killing.

These ninjas couldn't even hold back and threw themselves into the chaotic Earth Kingdom to enjoy the fun of fighting and killing.

What a perfect guinea pig.

As Konoha ninjas entered the Earth Kingdom on a large scale, there were countless such fighting madmen.

Ordinary ninja prisoners stay in prisoner-of-war camps, but these fighting maniacs and murderers cannot be imprisoned at will. Instead, they are transported thousands of miles to Konoha Village and imprisoned in special prisons.

These scum that are not suitable for the new era will be used as human experiment materials for the fourth generation Hokage Orochimaru, and contribute their final value to the ninja world.

It's just that Orochimaru is too busy right now and doesn't have much time to conduct experiments. He has actually accumulated a lot of experimental supplies.

These consumables are all murderous demons and unforgivable killers. They cannot be let go at all, but they are all ninjas who master chakra. Executing them directly is somewhat wasteful.

Orochimaru was very entangled, but Uchiha Yu happened to come over and asked Orochimaru for a test object to pay off his debt. He also specifically stated that the experiment was very dangerous and he wanted the damn test object.

The Fourth Hokage, who was in debt, was overjoyed and sent him two hundred.

Being able to exchange unrecoverable accounts for these consumables saved Uchiha Yuu a lot of time, and he was very satisfied with it.

There were too many experimental materials that could not be used up and could not be disposed of casually, but they could be used to offset debts. Orochimaru felt that he had made a lot of money.

It's a win-win this time.

Captured Ninja: You have made a profit, but we are miserable!

But these ninjas are not unjust, because times have changed.

The Leaf Village under the rule of the Fourth Hokage is the strongest and largest order system in the ninja world. In an ordered human society, some rules will become unbreakable iron laws.

Pay debts with money, kill with life.

When they wantonly kill ordinary people in the Earth Kingdom, they are destined to die a bad death. Being able to die from the experiment of traveling through time is an amazing experience.

No matter how vicious and angry these guys are, there is no room for resistance in Uchiha Yu's hands, they can only be "used" like little chickens.

When the experiment started, Uchiha Yuu was pleasantly surprised to find that the cost of soul travel was really small, not even one thousandth of that of physical travel, not to mention the impact of the huge chakra.

This cost advantage is so great that it can be said to be decisive.

Moreover, the return of the soul is more convenient and faster than the return of the physical body. The landing point will not be affected by the movement of time and space, and it can accurately return to the physical body.

The only problem is that the soul is fragile and may be destroyed at any time after being sent out.

There is no need for the big shock of the new parallel space-time tearing, even if there is a violent fluctuation of time and space, or if Uchiha Yuu's own hand trembles, the pure soul will disappear.

In order to protect fragile souls and increase the success rate of time travel, Yuu Uchiha collaborated with Tobirama Senju to develop dozens of sealing techniques for soul protection.

During this period, they also developed a new forbidden technique.

Forbidden Technique·Reincarnation in Dirty Land·Reincarnation

The function of this forbidden technique is very simple. Before the sacrifice used in the reincarnation of the dirty earth is completely damaged, the soul of the reincarnated earth can be replaced with a new body of the dirty earth.

In this way, Senju Tobirama successfully "extended his life" and was completely out of danger. Whatever backhand the Six Paths Sage left behind in the future ninja world would disappear with the destruction of the filthy earth body.

Senju Tobirama changed into a new body, just like Palu who was resurrected from the dead. He was back to his best condition, full of energy, and could continue to work overtime.

When two guys come together, one has endless whimsical ideas and the other has countless brain holes. The collision of ideas inspires countless inspirations.

Moreover, it was rare for Uchiha Yu to fall asleep, and Senju Tobijian had unlimited energy, so he could work non-stop, and the progress of his research was so fast.

They can carry out three to five versions every day, and each time they immediately verify it with experiments. After obtaining the results, they immediately summarize, either improve the seal, or start all over again.

The intensity of the experiment was really ridiculously high, and the bloody test items in his hands were quickly consumed. Uchiha Yu had to replenish them twice to get all Orochimaru's inventory.

As souls were kicked into the gate of the world one by one, Uchiha Yu's soul traveling technology steadily advanced, and the level of perfection quickly exceeded that of the earliest physical traveling.

In the summer of Konoha 48, Senju Tobirama and Uchiha Yuu carried out 100 consecutive soul travels in 11 days, all of which were successful.

A 100% success rate means that the development of soul time travel is completely successful and can be officially applied.

Uchiha Yu began to think about which unlucky person to choose for the official soul travel.

He must consider it carefully, because formal travelers must be given freedom and the right to know, so that they can gain as much intelligence as possible.

Therefore, the remaining experimental supplies are not enough. Their resistance is too strong and their hatred is too deep. After they are free, they will inevitably engage in crazy destruction.
