Konoha, I have the Herrscher of the End core in my body.

"You're back, but it seems he didn't come back with you." In the Land of Hot Springs, looking at Sasuke, Zabuza, and Haku who came back together, Naruto immediately realized that their mission had failed.

"I only brought back this." Sasuke said as he placed a pair of strangely shaped long swords in front of Naruto, Raitoga. The task that Naruto had asked Sasuke and the other two to do before was to see if they could win over Kuroki Raiga.

Relying on the memories of his previous life and combining it with the information of this world, he knew that Kuroko Raiga, one of the Seven Ninja Swordsmen of the Mist Ninja, was wandering outside, but he didn't know exactly where he was. He only learned of his whereabouts from Kabuto Yakushi not long ago, and then he asked Sasuke to accompany Zabuza, the successor of the Seven Ninja Swordsmen, to see if he could win him over.

"Rai Toga, why don't you keep it?" Naruto picked up the Rai Toga in front of him and couldn't help but look at Sasuke curiously. With Sasuke's own chakra attributes, this sword is actually very suitable for him.

"I don't like using dual blades."

Sasuke directly stated the reason. Although Sasuke now has Wood Release and has learned the Rasengan and Flying Thunder God Technique, he still mainly uses Lightning Release when fighting the enemy in normal times. With the training method of Lightning Release in the Cloud Village provided by Naruto, his attainments in Lightning Release are now stronger than in the original work.

Normally, Sasuke usually uses a one-handed sword, and there is no change in this.

"It seems like I have to find Orochimaru to get the Kusanagi sword." Since Sasuke doesn't want the Raiga sword, Naruto can only find a way to get the Kusanagi sword that he had in the original work.

"As for this pair of Thunder Fang swords, I wonder if Shuiyue will like them."

As long as Zabuza is alive, Suigetsu naturally won't be able to get the beheading sword. Although Naruto can use the power of the Herrscher of Reason to create one, the Seven Ninja Swordsmen are meaningful only when they are unique. If they can be wholesaled, wouldn't it appear mediocre?

"Tell me what happened." Naruto asked Sasuke about the mission while holding the Raiga Swords in both hands and using Honkai energy to begin replicating them.

Naruto, who possesses the Herrscher of Lightning, can actually use the dual swords, but he doesn't need this little bit of amplification. He constructed them with the power of the Herrscher of Reason just to keep them as inventory. Of course, sometimes when he is free, he can construct them to play with, just like the beheading sword. If possible, he wants to copy all seven swords.

"Did you meet Kai and the others?"

After listening to Sasuke's narration, Naruto knew why they failed. Konoha also took on related tasks. Although Konoha lost a large number of tasks due to heavy losses, those were mainly tasks from foreign countries or wealthy people. They were still responsible for most of the tasks in the Fire Country.

Kurochu Raiga occupied a village and killed people at will in the village by pretending to hold a funeral. Finally, someone was unwilling to let this go on and ran to Konoha to issue a mission.

Although Raiga is very powerful, there is still some gap compared to Gai, not to mention that Gai has Neji, Rock Lee, and Tenten by his side. Although Raiga has a companion, he is not very strong.

Finally, when Sasuke and the others arrived, the battle was almost over, so Sasuke and the others took Raitouga away. Kai and the others did not try to stop them. Raitouga was indeed a good weapon, but it belonged to the Mist Village after all. If Konoha took it away, the most likely outcome would be to return the sword to the Mist Village through negotiations.

In the original work, after the Fourth Ninja World War, Killer Bee's sword Samehada was returned to the Mist Village, as well as Kakashi's beheading sword. The confrontation at the national level is completely different from that between individuals.

"Ranmaru, Red Eyes, never mind, one more bloodline limit is enough."

According to Sasuke's narration, Kuroko Raiga's companion is a young man with a unique bloodline limit, who has the ability to make the Byakugan ineffective and also has powerful perception abilities.

If it were anyone else who knew that someone possessed such a bloodline limit, they would definitely not let him go, but neither Gai Ban nor Zabuza took action against him and allowed the young man to stay in the mountain village.

For a moment Naruto wanted to ask someone to bring him back, but after thinking about it, he gave up. The other party chose to stay in the small mountain village on his own initiative. Both Gai and Haku had invited him, but he refused.

Bai saw his own shadow in him. Strictly speaking, the two of them were indeed somewhat similar. They were both hated by others because of their bloodline limits when they were young.

The power possessed by the bloodline limit is indeed somewhat monster-like to those mountain villagers who have hardly left the village and have little contact with the outside world.

"By the way, this is for you." After listening to Sasuke's narration, Naruto suddenly threw him a scroll.

"What is this?" Sasuke asked directly after taking the scroll.

"A method of practicing cell activation that can increase the potential of body cells and enhance the speed of chakra extraction and recovery."

The power of chakra comes from the cells in the human body. Enhancing the activity of cells in the body will naturally increase the chakra. Shennong's cell activation technique is very unique in this regard. This is of no use to Naruto, but it is very suitable for Sasuke, Bai and others.

"Take this to find Karin and ask her to take you to find Suigetsu Hozuki. He will be a member of your team in the future." Naruto then handed the Raitoga in his hand to Sasuke. In the original work, Suigetsu Hozuki was a member of Sasuke's Hawk Squad, so it would be better to let Sasuke talk to him himself.

Companions in the ninja world are very important. Even the younger brother that Itachi always calls stupid, Kisame is always by his side.

Among the five major countries, the Wind Kingdom has the largest land area, which is larger than the land areas of the Earth Kingdom and the Fire Kingdom combined. Unfortunately, most of it is desert area, and the number of cities and population it has are the lowest among the five major countries.

The desert area is very dangerous. If you get lost in it, even a senior ninja will be in great danger. This is probably why not many people go back to the Sand Village to commission missions. After all, unless it is necessary, most people probably don't want to cross the hot desert.

"Is this the legendary Loulan? I didn't expect to hear this name in the ninja world."

After separating from Sasuke and the others, Naruto immediately came to the Kingdom of Wind, and after some effort, he finally found the ruins of Loulan in the desert, which is where the dragon vein is located.

"It is indeed a sealing technique unique to the Uzumaki clan. The next step is to absorb the power of the dragon vein. I wonder if it will increase the time-related abilities in the Herrscher core."

As for the Herrschers, Naruto originally thought that there would be a Herrscher of Time among them, but it turned out that he was overthinking. There was no Herrscher of Time among the Herrschers of the End. The legendary Thirteenth Herrscher did not possess the power of time.

There is also no Herrscher in terms of souls. If the Ninja World had the power to control souls, it would not be difficult to resurrect a person. They could just resurrect the person through the Impure World Reincarnation, clone a body, and then stuff the soul into it. Although this method of resurrection is not as perfect as the Reincarnation Technique, it does not require much cost.

For some reason, the rules between the human world and the underworld in the ninja world are very weak. If it were in other worlds, it would not be so easy to pull a large number of dead people out of the underworld.

"Haha, Loulan, the dragon vein, I finally found it." Just as Naruto was carefully looking at the seal left by Minato Namikaze, suddenly a figure broke into the Loulan ruins.

"A traitor from the Sand Village?" Looking at the figure of Forehead-Sang wearing a Sand Village forehead protector with a horizontal stroke across it, Naruto immediately understood his identity. He was speechless about the unspoken rules of this traitor in the ninja world. Since leaving Konoha, he had no idea where he had thrown his forehead protector.

"What are you doing here, you little brat?" The skinny rebel ninja from the Sand Village was a little wary at first after seeing Naruto, but after realizing that he was just a teenager, his attitude immediately became arrogant.

"I should be the one asking you, what are you doing here as a rebel ninja?"

"Little devil, you are looking for death."

As the man spoke, he summoned a centipede-shaped puppet, and then controlled the centipede to fly towards Naruto. Seeing the Sand Ninja rebel in front of him taking action, Naruto was not polite and directly used several wind blades to destroy the centipede puppet controlled by him, and then a golden chain pierced through his body.

"The rebel ninja of Sand Village, Centipede, wants to devour the power of the dragon vein and take revenge on Sand Village. In this case, he should be the enemy of Naruto in the original work."

Naruto naturally remembered very clearly what happened on the dragon vein, but he could not quite remember who his enemies were there. To be more precise, he probably didn't care much.

"Speaking of which, the puppet-making technology of the Sand Village is very good, but it's a pity that they have taken the wrong path." With a wave of his hand, under the power of the wind, the fragments of the centipede puppet on the ground flew into Naruto's hands. Looking at the very delicately crafted parts, he couldn't help but shook his head slightly.

Among the five major ninja villages, the Sand Village is the weakest because most of its ninjas are puppeteers or wind-style ninjas. Wind-style ninjas are fine, but Naruto has a different opinion about puppeteers. In his opinion, the Sand Ninjas who use puppet strings to control puppets are inferior.

It is entirely possible to create powerful puppets that one can control inside the body. For example, Scorpion's Hiruko has already had a prototype in this regard. If one goes further, one can completely create a humanoid mecha. The strength of the Sand Ninja's puppeteer lies mainly in controlling the puppets. Their own strength is not strong. Once the enemy gets close to them, they will be in danger. But what if it is a humanoid mecha? If they can create a Gundam, then even facing Uchiha Madara and the first Hokage will not be a problem.

But after all, he is not a Sand Ninja, so there is naturally no need to tell them how to develop. Strictly speaking, only when the scientific ninja world develops can the Sand Village be the strongest. In the Boruto period, there was already a Gatling gun in the ninja world, which can be used to equip the puppets and build a huge turret.

"Uchiha Madara, times have changed." At this moment Naruto couldn't help but think of some spoof videos he had seen in his previous life. Although it was a spoof, it was also a direction of development. After all, the Ninja Gatling gun and drones appeared behind him.

"Come to think of it, the puppets controlled by the Ruler also seem to use strings."

"Okay, it's time to get down to business." After shaking his head to get rid of the strange ideas in his mind, Naruto directly killed the Centipede, his archenemy in the original work.

"Time, space, what is time after all."

After unlocking the seal of the dragon vein, when Naruto was absorbing the power of the dragon vein, doubts about time suddenly came to his mind. The word time sounds simple and many people understand its meaning, but if you look into it more deeply, you will find that it is very difficult to understand.

For example, the legendary grandmother paradox, which means that if you travel back in time and kill your grandmother, will you still exist? If you don’t exist, how can you go back in time to kill your grandmother? This is a question that has stumped many philosophers.

However, some people have a different view on this, that is, there is no such thing as grandmother paradox at all, because killing your grandmother is your future, not your past.

Simply put, what you think is traveling to the past is not the past at all, but your future.

"Damn, I almost got trapped. Existence is the truth." Naruto soon realized that something was wrong with him, and then restrained his thoughts. His wild thoughts just now caused the dragon vein to riot, but as he stopped his wild thoughts, the dragon gate slowly calmed down.

For Naruto, there are many things that cannot be explored in depth, like his traveling to the Ninja World, which seemed impossible in his previous life, not to mention the existence of a Herrscher Core. But the fact is that he does exist here, so there is no need to consider anything else.

The existence of the world and time will drive people crazy if you think about them carefully. Many scientists commit suicide because they think too much, such as whether the world is real.

It seems that the Immortal Emperor of a certain world collapsed and disappeared because of this problem.

If the Ninja World is fake, then who can guarantee that the real world is real, and not another story like the Ninja World? In the real world, there is a saying that the world was born five minutes ago.

“So, isn’t it arrogant to think about time with human thinking and think that changing the past will affect the future?”

Looking at the Herrscher in front of him and the town built around the oasis, Naruto suddenly laughed.

This is Loulan. The power of the dragon vein had surged before, and he followed the passage and came here.

"With this power, it seems that I can only stay here for six days at most. If I don't go back, I will never be able to go back. Although the time is a bit short, it is enough. Let's prove whether the changes here will affect the future or open another world line."

After a brief silence, Naruto immediately decided on his next course of action.

"I don't know what time it is now, Shadow Clone Jutsu."

Naruto then began to summon his shadow clones. He did not use the Multiple Shadow Clone Technique. Instead, he summoned one shadow clone first, then waited for it to recover before summoning another one.

Although the Multiple Shadow Clone Technique can summon a large number of physical clones at once, it will divide the power of the main body equally. If ten shadow clones are summoned, each clone will only have one-tenth of the power;

If one's own strength recovers quickly, one can summon a shadow clone at a time, so that one can summon several clones with half of one's own strength. This method is not very useful for ordinary people, but for Naruto, it is very meaningful.

The effect of a ninjutsu depends on the user.
